Rubber Roofing (EPDM) – Pros and Cons of using rubber flat roofs.
Rubber roofing (EPDM single ply membranes) it the most common flat roofing system in New England (MA, CT, NH, RI, etc.) and the rest of US flat roofing marker – most people refer to a flat roof as “rubber roof”. The main reason for such popularity of rubber roofs is the lower initial roof price. However, rubber roofs have many inherent problems, which cannot be solved by technology, because of the rubber roof’s design, as well as issues with unprofessional roofing contractors claiming to be “rubber roofing pros“.
What you need to know about Rubber Roofing:
There is much confusion about rubber roofing, as well as misunderstanding of its benefits and limitations. In this article we will try to clear up the confusion and show you that rubber roofing is NOT the best flat roofing material, and there are better and cheaper alternatives to rubber.
If you have a leaking rubber roof in Massachusetts, Connecticut or Rhode Island we can give you a roofing price quote to replace your rubber roof with our flat roofing material of choice – a new, lifetime PVC Flat roof manufactured by IB Roof Systems. We can also repair your rubber roof at a relatively low cost, using only the best materials that rubber systems have, and extend the life of your rubber roof by a few years. One example of such materials are peel-and-stick flashing and seam tapes. We do not use black rubber glue as it is outdated, and leaks much faster.

EPDM Rubber roofing and flat roof homes.
Homeowners with flat roof homes often find themselves in a situation where their roof starts to leak rather unexpectedly – i.e. only after a few years since the roof was installed. This for the most part happens to homes that have a rubber roof on them. While most flat roofs will only last 10-15 years, older systems such as Tar & Gravel, Bur and in some cases Modified bitumen roofs are usually installed by roofing contractors that are somewhat specialized in their scope of work – these are “the old-timers” or former union guys that decided to try their luck working for themselves, and they actually went through special training and have years of experience. The problem is that roofing systems they install do not last long for many reasons outside the scope of this article.
Homes that have a rubber roof begin to leak well before their minimal life expectancy is reached because in many cases they are roofed by your typical shingle roofing contractor that is so confident in his/her abilities, and a rubber roof is merely a roof with a low slope.
Why rubber roofs are so popular?
The truth is, rubber roofs (EPDM) are the most used flat roofing products in the US / Canadian commercial roofing market. Rubber roofs we first put in service over 40 years ago, and since gained popularity among roofing contractors and their customers. The reason for such success lyes in the condition of the flat roofing market at that time and the available alternatives.
Back in 1960′s oil was still very cheap, it was more than a decade before the oil crisis of the 70′s and there wasn’t that much demand for oil. The oil refining process was far from being efficient and the industry was looking to get rid of many by-products of the oil refining process.
At the same time, the flat roofing industry was the same as at the turn of the 19th century, and the most common product to use on a flat roof was either a BUR (built-up roofing, using multiple layers of tar paper, saturated in hot tar or hot asphalt) or Tar & Gravel roofing, which was essentially a BUR roof with gravel added for additional protection. Flat roofing technology has not changed for 100 years and contractors needed a new, easier to install and cleaner product, hence, the EPDM was born.
EPDM consists mainly of oil (carbo-hydrate) based by-products with some modifiers and stabilizers added to extend its service life. Rubber roofing was cheap to produce, easier to install than conventional (BUR) roofs, did not require any special equipment to put it down and the membrane could potentially last for decades, as it was UV stable and did not break down when exposed to the weather.
Because rubber roofing was cheap, quick to install, and offered a potentially long service life, and with lack of any opposition from better roofing products, it quickly became the king of flat roofing and the pioneer of the single-ply flat roofing market.

So this really isn’t about the pros and cons of the roofing system itself but more of a soapbox platform for UNIONS?

Nathan,
I’m confused about your comment. The article is aimed to show people the negative sides of rubber roofing – EPDM – and not ot promote some soapbox platform that you are referring to or UNIONS. In fact I’m for the most part against unions and we are not a union roofer, and in no way does this article promote or even refers to unions.
Basically I have no idea what you are talking about.

I have installed almost every imaginable roofing system available, both residential & commercial.
There is nothing wrong with EPDM rubber roofs. Yes they must be installed correctly.
The training from Carlisle, Goodyear/Versico and other I have experienced were more than 1/5 hrs long and covered much more. Also, every person that attended performed the procedures taught right there on the “test board”. NO, any roofer CANNOT just pick up some EPDM supplies at the local supply house and install it with a warranty from the manufacturer. Any of the GOOD EPDM manufacturers require the installers to be certified! The before the warranty is awarded, the roof & all details etc, MUST be inspected by an inspector via the manufacturer or an independent inspector approved by that company. The upper class manufacturers even offer incentives for so many excellent passing inspections. If anything fails, the smaller things if any can be repaired right then and reinspected. Larger problems must be corrected and reinspected.
SO you sir are full of crap! And merely trying to sell you so called “System”. That if was as truly as great as you say, would be more popular and a standard rather than a fly on the wall, OBSCURE system, like so many before it. I can bet this gets taken off the site here, and if it does, I will post on forums everywhere.
PVC? Are you kidding me? Ive installed those also, heat welded failures. The PVC breaks down and leaks 10x faster than any EPDM or even modified bitumen roof. Your a complete line of BS, and any fool that pays you to put a roof on their house or business without doing their own research will regret every cent.
If that is a photo of you 2 twenty something no nothings, you never were a “roofer” and never will be.
What is you vast years of experience, jobs you have done & scope of the work you performed. Seems like a business course college failure selling BS on the internet.
You’re a snake oil salesman, and like most the rest, prey on consumers lack of knowledge, misinformation and fears. I hope karma comes back to you 10 fold just as you deserve it. Your no roofer, but you slept at a Holiday Inn last night. SCAMMMMM ALERT~!!!!!!!!!!!!!!!!!!!!
PVC LMAO!!!!!!!!!!!!!!! Oh and the “Green” friendly roof system. Explain to your customers about the PVC itself and what is in it and how it is made, then how it is disposed of and where that goes? And also explain the chemicals involved in the washes & caulks etc. Pathetic. You aren’t roofers, your internet marketing kids, selling BS. Good luck with that PVC. I look forward to watching you flop!

Fact of the matter is, no roofing system goes without it’s flaws.
Given the experience of almost all the systems out there. And being around long enough to see the pluses & minuses of each system. I have seen how each has typical failures. Whether breaking down and becoming brittle as PVC does, especially in more extreme climates very hot to very cold seasons etc. The attempts to reactivate the product once it cures etc. in cases of needed repairs additions with tie-ins etc. And I have seen less than experienced folks overheat, under heat the welds etc.
EPDM field membrane is infinite. The adhesive in the seams, uncured/neoprene flashings etc, will start to fail as early as ten years, sometimes they will last 15 or 20. I have also seen inexperienced folks not mix the adhesive properly, not apply the proper thickness or coverage of adhesive, and over work/stretch the flashings to the point where they are paper thin. Or not cleaned enough and not properly adhered.
Both are more prone to penetrations, but once complete, really should not have the opportunity to be penetrated other than when maintenance on roof units/ AC etc are performed. Some mechanics are just don’t care, what happens to the roof, or will purposely oops to make the roofer’s life miserable on purpose.
Modified is an ok system, but needs more maintenance and if not properly/periodically coated. They will fail in 10 years or less. And as any other system, the installing mechanic needs to know what he is doing and have experience when it is being installed. This is the torch down system. The cold applied is pure garbage.
PVC is PVC, in time, and exposure to the sun, air pollution & the enviornment, it will break down, become brittle, and I have personally seen how it delaminates as it breaks down. The old Gates system was notorious for this. As well as becoming completely unable to be reactivated once cured.
There is nothing wrong with trying to sell your product that you may believe in, or maybe that is the one you can sell and warrant without being certified to install and obtain warranty for from the manufacturer. That is business. I wonder what your real roof time & roofing/installation experience is? How many systems have you put on? I would put money on the fact that I was on a roof laying rubber, torching modified, heat welding PVC, and slopping down hot tar before you were even born, or damn near close.
No one on a roof should be wearing a white shirt. If you are you don’t belong up there. Or your an architect that is scratching his head, cause “it worked out on paper and the drawings”. But in real life, it ain’t even close.
Good luck to you. But downplaying one time proven, widely acceptable, specified and respected product, to sell your own, first off eliminates a product you may want to sell in the future. And especially when preying on consumers lack of knowledge & fears, always come bask to bite you in the you know what.
But down playing another product as inferior as the “one” you sell, is just plain BS. And praying on the consumer’s fears to sell your product.
My name is Rob Leonard btw, and I live in Berwick, PA. And have nothing to hide, and no one to hide from.
And yes, I am a real roofer. Not a carpenter, not a drywall installer, not a jack of all trades, master of none.
I am and a damn good sheet metal mechanic also.

All “flat” (i.e. low-slope) membrane-type roofing products are problematic from an environmental and performance perspective.
In terms of lowest environmental impact and highest performance, the best choice would be to design buildings to use “pitched” roof systems, e.g. shingles, slates, tiles (i.e., 3:12 slope or greater) or use sheet metal roofing systems (50+ years).
That being said, in terms of environmental impact (in terms of both manufacture and disposal), PVC-based systems (and other chlorinated synthetic membranes) are the absolute worst.
PVC-based products in general (roofing, windows, gutters/downspouts, piping, etc) are very environmentally problematic and present significant toxic and occupational health issues (e.g. contain hormone disrupters) They should not be used and should be phased out of manufacture entirely as soon as possible.
Though I am not an enthusiastic EPDM supporter, as far as low-slope roofing systems go, EPDM has a relatively low environmental impact and presents no issues regarding human toxicity. Furthermore, test data demonstrates that EPDM membranes are the most durable over a range of temperatures, whereas, reinforced PVC, CPE and CSM sheets show lower low-temperature durability.
The key to the long-term performance of EPDM roofs (any roof for that matter) is proper design and quality installation (20-25 years).

Is it OK to clean rubber roofs by power washing? Or is that likely to compromise the sealed seams? Can I paint it with any reflective paint? Or is there a particular type?
Judith Zawojewski
10 Sep 10 at 8:47 am
Hello Judith,
You can probably do it if you are extra careful not to point the nozzle of the power washer at the seams or any flashing, as the hi pressure water will pop those seams open.
If it was me I would not do it unless there was a specific reason – like the reflective paint application to make your rubber roof cooler.
If you will be power washing it, do not rush through the process, point the power washer in the direction of the seams – not against them. This way you should not damage your seams. When it comes to penetration flashing, again do not point the flow at the seam, as to not pop it open.
As far as reflective paint – I would actually recommend using an acrylic or a urethane coating, instead of simple silver paint from the home depot. The acrylic or urethane (preferred) coating will actually extend the life of your roof, by about 10 years, as it will create an additional waterproofing layer, as well as make your roof cool.
Silver paint is a gimmick – it does make your roof cooler, but not as cool as white coating. Silver paint is not a waterproofing layer. It will also become a problem later, when you need to repair your roof – it will prevent the flashing from sticking to the rubber. I recommend you not use the silver coating.
Best of luck.

[...] Most popular type of flat roofing materials is the Rubber Roofing (though it’s quickly loosing ground to the newer creation of commercial roofing world – TPO roofs). As is the case with asphalt shingles, rubber roofing is rather easy to install, cheap and therefore is more popular today than other types of flat roofs. At the same time it attracts many hack roofing contractors, so we recommend you use caution when considering installation of a rubber roof. [...]

I am in need of replacing my rubber roof on top of my restaurant and was wondering if you are aware of any “how to” books. I have read your entire website, and aware of certain ups and downs. I will be searching for other knowledge also. I have a friend who is very handy and does great quality work, and his brother installed a rubber roof more than 5 years ago (no leaks yet). So, as I said I’m just researching as of now. Any help on this would be greatly appreciated.

Hi,
I have two quotes and would like your opinion. We are replacing a flat roof (2200 sq ft) on a commercial buildings in northern NJ. One quote is to install rubber coat with torches on entire roof and then the entire roof will receive a top coating of aluminum roof coating for $9500.00. The other proposal is for installation of insulation and Firestone or GFA TPO roof for $14,995.00. Both include removing 1/3 the roof down to the plywood and replacing the plywood, sealing all seems, removing all debris. Which material is better? Which material will last longer? Is it worth paying the higher price? thanks for any help or feedback.
Joe
24 Feb 11 at 10:16 am
Hi Joe,
I’m a little confused about the first option – if you rephrased the material name, then let me know what it is called on the quote. If that’s what the quote says then the roofer has no idea what he is talking about. In any case I suspect the first quote is a smooth surface modified bitumen (which should actually be at least a 2-3 ply system) … Also aluminum coating is pretty useless – it’s only good for sun reflection…
As far as TPO – I’m not a big fan of that junk at all. Besides – in NJ you can get PVC for almost the same price, and it will work so much better for you.
Look at it this way – TPO will last – actually no one knows how long it will last, not even the manufacturers, as the keep changing the product to keep up with failures… PVC is known to last 25-30+ years easily.
Is it worth paying more – I think so… the outdated mod. bit. usually lasts 12-15 years, and if you have ponding water, it will leak.
Read about the PVC roofing that we install.
Good luck… let me know what you decide to do.

we live in the hillsides in southern california and have a badly leaking flat roof; it’s already water-stained our new kitchen wood paneling as well as our ceilings throughout the house
so, it’s time to bite the bullet;
our current roof was installed about 30 years ago, then repaired and patched many times on top of the original; so we’ve got a multi-layer leaking roof
i believe it’s tar paper, with lots of hot mopping tar on top, in multiple layers, as mentioned
while our roof is flat, it’s also at least two different levels, oddly; we’ve got a raised 3 foot wide border all around the periphery, on one side; on the other side of the house, the 3 foot wide periphery is lower than the main interior portion of the roof; all flat surfaced.
we wish a roof that will last us, without leaks; we get very, very heavy torrential rains in winter
any advice will be much appreciated; thanks in advance

Hi, I’ve just been going through your site with great interest. with regards to your undoubted bias and savaging of Rubber Roofing, I have to totally disagree with you. Here in New Zealand I have been a membrane Installer of all types ( modified bitumen, PVC,TPO, Butyl, EPDM ) for over 30 years, and I can say your blistering criticism of Rubber Roofing has absolutely nothing to do with the weatherproofing characteristics of the membrane, but the absolutely appalling workmanship of the roofs you have looked at. When I look at your videos and pictures I have to agree with you, but only as far as the application of the product. Such roofs would never have been accepted or passed here, let alone paid for! I have many pictures of what a properly installed Rubber Roof should look like and will gladly upload them to you so you can see for yourself what an aesthetically pleasing product it is when Installed by Approved Applicators. In our high Ultra Violet and Infra Red climate, Rubber Roofs,Butyl and EPDM perform exceptional well as a single ply system. As in most things preparation is the key. Down here in new Zealand we lay rubber in Residential Applications to Plywood substrates and for concrete and over asphalt shingles or bitumen, we use a Felt backed Rubber to separate the two different materials. We also tend to fully adhere the rubber to the substrate with specially formulated contact adhesives, which are specific to the program. All laps have their own solvent wash and lap primer program along with super seal bonding tapes which are laboratory certified waterproof adhesives, so water does not break down the contact area. We always roll out the rubber and allow it to relax for 20 to 30 mins before installing to allow it to lose any tension. However as it is generally a fine day and warm, we are aware the rubber is already in a expanded state when we lay, so when we detail, ( up parapet walls, outside corners, etc ) we also allow ease into the target area. This is so when the membrane cools and shrinks as the temperature drops, the ease is taken up and stops the membrane from pulling allow away from the corner. Rubber membranes in this country are the only membranes which have a 20 year unlimited warranty, the others including PVC have only a 10 year warranty or the occasional 15 year limited warranty. Any product to be used on a building and be accepted by a Territorial Authority must be approved by our Regulatory Authority which is known as BRANZ, Here is the BRANZ link for EPDM where the serviceable expectancy is 20 years. Listed under Durability, Serviceable Life, Section 9.1

As you can see, we don’t make wildly exaggerated claims down here, but like to be more conservative. Rubber Roofing is rated higher than its plastic cousins for one reason, it’s proven itself to hold its characteristics longer. Period. Like I said at the beginning, the workmanship of the membrane Installers in America are obviously of an appalling standard, not the membrane itself, and in no way would be acceptable down here. Even the quality of some of your installed PVC roofs would not pass here. Attention to detail, and pleasing to the eye, as well as good waterproofing application practices, are applicable to any membrane type for the supplier to be able to deliver a SUPERIOR SERVICE to his customer. Thats is how we work down here.

hi,
looking at replacing a commercial flat roof and not sure what material to use after reading your info…by the way thought that it was very informative. It’s leaking and needs to be replaced but confused was told rubber was good but after seeing the pictures hesitant to use it. Is tar and gravel out of date or could you recommend a product/ procedure to install on flat roof.
Thank you

Ray
25 Aug 11 at 2:39 pm
Ray,
I think you need to learn how to spell “scum bag”. Also it’s bad manners to post profanities on someone else’s site. I approved you comment to make a point. Here it is:
Rubber roof is junk!
Besides the fact that seams will break apart and roof will leak, there is way too much roof for installation error with all the seam tapes / cover tapes, flashing contraction, bad adhesion, etc.
However, my biggest issue with rubber roofing is the fact that TOO many hack contractors (like you
) can easily install it rather cheaply (and that is the only way you can get the job – by offering low price), and then homeowner / business owner is stuck with crappy roof that needs hundreds or even thousands of dollars in repairs. Because you can buy rubber anywhere (now even Home Depot sells it) and do not need to invest more than $200 in installation tools, rubber attracts so many “real roofers” (not saying that Real Roofer guy from the comments above is a hack) who have no idea what they are doing, and screw the consumer, who buys into lower price tag deal.
And once a rubber roof is installed, and starts leaking – roof owner has no real remedy to force a hack roofer to fix it, so they have to hire professionals to repair their roof. And way too often the roof is beyond repair.
Here is a video of a commercial roof on a condo building which is ONLY 6 years old and is a complete FUBAR – hack roofers just had a field day with this one:
Bottom line – no one is immune from crappy installation. However, with rubber roof, your chance of getting a hack roofer is SO much higher that with PVC roof, which requires substantial investment in installation equipment, which hack roofer will never do. So your chances are much slimmer with premium roofing materials, and PVC roof will outlast Rubber roof any day!
Ray – I recommend you stick with asphalt shingles and leave flat roofs to professionals ( us
). Also, unless your comments are polite, they will go to spam!

@ Real Roofer
Rob – I never had a chance to properly reply to either of your comments.
First of all, I do not doubt your roofing abilities, but as you have read – I find it common place practice that roofers with ZERO flat roofing experience install rubber roofs (because it’s the cheapest and easiest to slap together product) left and right, and then we go out and repair or replace these fairly new roofs – often 1 – 5 years old. For me – rubber roof is a combination of problems – bad seams / flashing and TOO many hack roofers installing it.
That said, here is my response to you second comment:
We are a certified IB Roof installer. IB Roofs does not sell it’s products through distribution – only to licensed contractors.
It is much more difficult to sell IB roof vs. rubber roof / TPO and other cheaper products, mainly because people are cost conscious. And yes, we like IB Roof because of it’s lifetime warranty on residential flat roofs.
All PVC roofs are different. IB roof does not cure, and remains weldable after 30+ years. So are some other PVC roofs. Here is a PVC Roof Repair article that I wrote a while back about Trocal and Sarnafil PVC roof repair.
Additionally, here is a video demonstrating a 30 years old sample of IB PVC roof, and as you can see it is not cured, and is VERY flexible.
I will make another video very soon to demonstrate how it welds together, and to the new IB material (stay tuned).
I think the only reason why rubber is “time proven, widely acceptable, specified and respected product”, is because it cost’s a lot less than PVC roofs in general. Hence it is specified and chosen by roof owners.
As far as preying on consumer’s lack of knowledge – I think I explain it an all the details I can include, to show that why I believe rubber roof is a waste of money. Yest it will work on straight roofs with no penetrations, but once you get into complicated stuff, flashing on rubber roof fails (and so does the Mod. Bit). I actually believe that I inform the consumers of more than likely outcome of installing a rubber roof – especially a residential rubber roof, because that is where most of bad installs take place.
As far as wearing a white shirt – that picture is from a dance competition taken in 2006 (i could not wear a dirty roofing shirt
). And I am a real roofer too – not a college kid as you say. A roofer with college degree in computers and business management. And I’ve been roofing for more than 7 years, and all that time (except for 3 months training) as a roofing business-owner – not a grunt who gets paid $12 / hr, and only cares about going home at 5 pm.
All my roofs are installed with one basic premise – the roof MUST NOT LEAK – I do not want to make free-to-me trips to fix my bad work, and have a pi$$ed off customer. I want happy customers, who will give me good references! So I do the best work I can and go above an beyond.
The night before I start a new roofing job, I only get 3 hours of sleep, because I keep thinking about the details of tomorrow’s job, and how to make the flashing work, and how to make sure roof does not leak if it rains overnight, and cannot for asleep.
You think a $12/hr grunt thinks about that? I don’t think so.
Yes, I’m not an old timer, and do not have 30 years experience, but I’m only 29. However, about of roofing knowledge and hand-on experience that I have, and research on roofing that I do, is more than many old-timers will ever have. I only know how to install torch-down mod. bit. or hot-mop tar and gravel roof in theory – merely because I do not want to install them and never will. I don’t need to know those systems because they are outdated and inferior in my opinion. But I know how to install PVC / TPO / Rubber roof / Metal Roofing (Standing seam / copper / zinc / metal shingles / stone coated steel tiles / roof coatings ) well, because we install them (except for tpo / rubber), I honestly believe that I’m better at it than most roof mechanics (not all) – mainly because I do care about end product.
Well… I think this is enough rambling
I appreciate your input, and I find your first comment, most hilarious that I’ve had on this website ! That’s why I approved it without editing.

It’s funny that you blast everyone of these guys that criticize you for their typos. Have you read your own work?
I have installed many EPDM roofs over the years. I have replaced systems installed by hacks as well as systems installed by large, unionized commercial contractors. I’ve also replaced my own work a time or two (no one is perfect). EPDM does have inherent problems, yes, but it still has a place in the market. EPDM survives because it is cheap and accessible, and when properly installed works just fine. Personally, I recommend SPF roofs to anyone that can afford one, but a lot of customers balk at the price. Those customers are looking for the cheap alternative and usually end up hiring cheap hacks to install EPDM. That doesn’t just happen in EPDM, but siding, concrete, windows, and everything else. The customer looking for the cheapest contractor usually gets the worst work. Your claim that no one other than a large commercial company can properly install EPDM is preposterous.

Hi Bob,
Can you please elaborate on the “Wish I knew this earlier” part? Did you have a hack rubber roof installed?

I am a carpenter. Really I know almost nothing about flat roofs, except when I go to purchase a property that has one, to avoid it. I always tell people you don’t need to fully understand something to make a correct choice. Common sense goes a LONG way. I guess at 29 (like 16 or any young age) you think you know it all. That really comes across on your site. I agree with “Real Roofer” (except for the “good marketing” comment).
Before a few hours ago, I had never heard of EPDM,but when I watch your video and read your comments, I knew you where one of those people who will say anything to push your own products. How about some stats on how many rubber roofs are installed each year (properly) and how many of those fail. All you did is find the worst examples of poor roof installs, and combined them together in your video. No doubt, to scare people as other suggest. Too bad…

I’ve only been in the Boston area for 6 months but have noticed the amount of EPDM or as I hear them called “rubbah” roofs. The main problem is the failing seams when the glues give way. And it is going to inherently happen because glues fail. PVC is permentently bonded by heating and melting the two overlaps of two membranes. Impenetrable. The PVC failures being referred to are with regards to un-reinforced membranes from the early years of single-ply manufacture (Trocal was one). Nowadays re-inforced membranes like IB’s PVC membranes have non-wicking scrim sandwiched between virgin PVC on both sides, with an acrylic top coat that keeps it cleaner and more reflective. White PVC should be installed over every single square foot of black roofing period, whether it is rubber or tar. White membranes lessen the heat island effect caused by dark roofs in cities. Facts are facts. Rubber is a temporary roof and is going to fail. PVC is going to last 4 or 5 decades. You’ll buy 3-5 rubber roofs in the lifespan of one 80 mil PVC roof. Just my opinion but I’ve never met a rubber membrane I wanted to put on anything.
