Roof Decks Leak Problems and Solutions – Many homes have an outside deck / patio over a living space, and so far, the solution to waterproof them was to install a rubber membrane roof and a wooden deck on slippers over the rubber. On some older roofs, instead of a rubber roof, a Tar / Built-up roofing material is used for waterproofing. The main problem with this assembly is leaks, which often occur within a few years of the roof deck’s installation.
Often the seams on the roofing membrane pop open, or water starts to pool under the deck, and the only way for this water to drain is into your home. If you need to repair such a roof deck, you will have to take it apart completely to seal the seams or to redo the roof flashing, and then put everything back together.
Another issue is the cost of such a roof deck (even without the high costs associated with roof repairs) – the rubber roof by itself is somewhat inexpensive, but when you add the cost of a pressure treated wood deck (a fiber decking, mahogany or some other premium deck is rather rare, and most people do choose to go with PT wood), your deck ends up costing a small fortune. Then, you also have to install and seal the railing posts.

Why you should not use rubber roof (EPDM) for roof decks:
On a rubber roof, pieces of uncured flashing must be glued to the rubber roof and the post to make the post penetration watertight, and on a Tar / BUR roof, liquid tar or roof cement is used to seal around the post. Both rubber roof flashing and tar flashing around the post will begin to fail after 5-7 years, so once again to stop the leaks, you will have to disassemble the deck and repair the flashing.
IB Deck Shield – the long lasting, beautiful and cost effective solution for roof decks
IB Roof Systems recognized the need for a long-lasting waterproofing membrane for roof decks, patios and balconies, and based on their excellent PVC roofing membrane, created a Deck Roofing product, which will last for decades, is easy to repair (if such need arises), and has a special, slip-resistant, beautiful surface. This makes it possible to walk on this surface, eliminating the need for a wooden deck over the membrane, and making the whole roof seamless and watertight.
IB Deck Shield was created based on IB Roofs’ proven PVC roofing membrane, designed for flat roofs, and featuring hot air welded seams, which make membrane overlaps sealed permanently, ensuring a long-lasting watertight roof. An IB roofing membrane can withstand ponding water, and is an excellent choice for any flat roof. IB roofs also have a complete line of flashing accessories – inside and outside corner flashings, pipe flashing ranging in size from 1/4″ to over 12 inches, for extra wide exhaust pipes and furnace stacks. Because of fast and easy installation in all tight spots, any roof penetration can be flashed quickly and any installation defects are eliminated.
IB took it’s existing PVC roof product (IB Flat Roof), and added a special surface to it, making it slip resistant, even when wet, and added a beautiful texture, which resembles small pebbles, often used as a swimming pool deck. All components of IB Deck Shield roof are color matching and will produce a uniform, great-looking final product.
IB Deck Shield roof installation:
Because an IB Deck Shield is exposed to constant foot traffic, deck furniture, outside BBQ grills, etc., it must withstand all this abuse and last for many years without any leaks. To be able to do so, an IB deck Shield is installed over a dense, moisture resistant substrate – DensDeck, which is attached to the roof deck.
Once DensDeck substrate is installed, all seams are taped and “plastered” with a special joint compound to provide a universal, smooth surface, to which the Deck Shield membrane is glued using either a water-based or solvent based adhesive (we use water based glue, as it is environmentally “safer” than a solvent based product).
When a a joint compound cures, we apply a layer of IB water-based adhesive and lay down the IB Deck Shield membrane, which was previously aligned to be wrinkle free and to have exactly a 2″ overlap with the previous sheet of membrane. Once adhesive is applied and membrane is laid down, it is mechanically fastened at all roof to wall connections, but never in field.
After a few minutes, when adhesive cures, all seams are welded and it’s time to install roof to wall flashing, as well as all pre-fabbed inside / outside corners, and all post penetrations. IB Roof manufactures special post flashings, which can either be pre-welded or split, and it is the choice of a contractor which one to use.
We prefer to use split post flashings – although the split post flashing requires more welding, it is actually easier to install than a welded flashing, because when we order them, we specify the post size – usually 3 5/8″ x 3 5/8″ (a standard 4×4′ railing post). By contrast, a welded flashing sits pretty tight around the post, so it is rather difficult to pull it all the way down.
Durability of IB DeckShield
Once all DensDeck is installed, all DeckShield is glued down, seams welded and all flashings are installed, the roof is complete, and now you have a durable, completely water-tight roof deck, where you can spend nice summer days, invite your friends over for BBQ, and not worry about roof leaks any more. IB DeckShield is VERY durable, and very resistant to puncture damage. Because it is glued to the DensDeck substrate, the surface under it is very hard and most sharp objects that fall on this roof will bounce off leaving very little or no damage – we accidentally dropped sharp tin snips; they just bounced off and did not cause any damage.
Of course you want to be careful with your new roof and not drop any sharp objects purposely, but small accidents do happen, and you can be confident that IB DeckShield will withstand all normal wear and tear – foot traffic and most accidental drops, which would usually puncture a flat roof such as rubber roofs.
Damages and Repairs
If your roof is damaged – in most cases it should be leaking for a long time, as the membrane is glued to the substrate and even if some water gets in, it won’t be able to spread and leak inside your home. It is also very easy to repair an IB Deck Shield roof – a small patch of color-matching membrane will be welded over the damaged area, making the repair virtually invisible, unless looked at from close distance. An IB DeckShield roof will remain weldable for decades, just like other IB Flat roofing products.
How Much Does IB DeckShield Cost to Install?
IB DeckShield is a premium flat roofing product and it is rather expensive by itself. However, when you consider the alternative of a rubber roof with a PT wooden deck over it, IB DeckShield will usually be less expensive, as PT wood deck will add a significant amount to the total roof deck cost.
Because IB DeckShield installation is rather complicated and involved, it will cost more than the flat roof prices provided by our roofing calculator. IB Deck Shield takes considerably longer to install than regular IB flat roofs, and costs a lot more than a standard 50-mil or even 80-mil IB roofing membrane. Therefore installation prices per sq. ft. of your roof deck will be higher than those of an 80 mil roof deck option (eg. flat roof deck in Wellesley, MA)
Price of IB Deck Shield installation will also depend or roof difficulty, number of roof penetrations and whether the existing roof needs to be removed. In case of a roof removal, the roof deck must be installed in sections, and sealed at the end of each work day, to prevent roof leaks from overnight rains.
IB Roof Deck Prices
A basic price to install IB DeckShield starts at $13-14 per sq. ft. (assuming that your roof deck is approximately 200-300 sq. ft., which is a typical size), and includes a 1/4″ DensDeck Substrate, with all joints sealed using joint compound, and up to 5 post flashing penetrations. All other flashing and penetration details will be priced, taking into account other aspects of your roof, and the project as a whole.
Roof tear-off will be priced in the range of $300+ per 100 sq. ft. of roof area, plus cost of the dumpster. The reason for this price structure is as follows: Roof decks are usually rather small, but the tear off greatly intensifies the installation difficulty and slows down the overall process. Also, we separate dumpster fees, as on a small roof we would still need the smallest (10 or 15 yards) dumpster, which costs about $300.
To give you an example – it took us about 5 days to complete the roof in the first picture on this page, with 4-5 guys working 8-10 hours per day. The roof size there is approximately 1200 sq. ft. So assume that 4-5 guys removed and installed about 240 sq. ft. of roof in 1 day.
The pricing above is approximate and reflects a general price structure that we use for deck roofs installation in Massachusetts and the rest of New England states (Roofs in CT, RI, NH, ME and VT).
We will price each roof deck separately, but this will provide you with pretty accurate pricing guidelines, so you would know how much to expect to pay for an IB DeckShield roof.
As a comparison, a rubber roof would cost you $8-10 per sq. ft. plus the cost of PT wooden deck, which can range from $13-20 per sq. ft., often without the material costs.

I had your product last October installed/adhered just over plywood decking.
I noticed that your website article recommends 1/4″ dens deck substrate over the plywood with joints plastered and filled with joint compound before even adhering the deck shield.
They didnt fill the joints or screw holes on the plywood, I have noticed some screw heads protruding on surface of the deck shield, and where the deck shield is welded to metal edge cap there is area behind it that isn’t fully adhered
My concern is will the protruding heads loose areas or other problems arise over time cause any leaks and if it should of had the densdeck put down first
This is my front porch over a room down stairs so don’t need any problems down the road

Any recommendations in Cleveland, OH? I am building a new house and I have a flat roof/balcony right off of the 2 master bedrooms on the 2nd floor.

We are using a 30 year membrane, but heard I need to have 4 plys. I like the Bison deck products that sits on top of round plastic so the wood does not sit right on top of the membrane, but the deck is already built and it is flush with the sliding glass doors off the master bedrooms, so I do not think I can use the Bison products.

Can this material be sold to home owner directly and installed by home owner?
Installed by homeowner – possibly, although without experience, its 99% likelihood you would botch it up pretty badly – no offence, it’s just a very tricky product to work with, and one needs to be very careful and there are so many nuances.
Sold to homeowners directly – no. IB roofs only sells to approved contractors. They want to see contractor’s work with other similar products, have experience, and demonstrate excellent workmanship, before approving anyone. Reason is rather selfish – they don’t want to ruin great product reputation by bad roofers… They don’t sell to homeowners, and this is my guess, because they don’t want to deal with customer service issues, when pretty much every homeowner would have a roof leak or “burned” seams or some other critical problem …
Bottom line – these product are complicated – it took me a long time to get good with it, and every roofer i trained on it, would take weeks to get decent to the point where I did not have to supervise and recheck ALL of their work.
PS … what i referred to about is concerning simple solid IB PVC roofing material, which my itself is much simpler than IB DeckShield…
Can you put terra cotta tiles over this product?
You could in theory, but it gets very technical … if your don’t consider following items, you may run into many trouble.
First, you would need to have separation between tiles and roof membrane (usually plastic “pedestals” are used). It is also important to consider placement of pedestals in regards to roof fasteners (you don’t want to put pedestal over a screw, because eventually that screw will poke a hole in a roof.
Second, roof insulation or substrate is an important factor. If substrate is soft, pedestal would compress it too much, and may cut the roof. Ideal is to have 1/2″ or even 5/8″ DensDeck installed over insulation to provide rigid surface for pedestals and not have any screws holding down the DensDeck.
You could have insulation screwed down, and DensDeck glued to insulation with two-part adhesives.
Third, you really need to consider the weight of terra-cotta tiles as well as snow load, and have a structural engineer tell you if your roof can support all that weight. Tiles could easily weight 10-20 lbs per sq. ft. or even more!
Hope this helps.

Can this be installed on an upper deck that is pressure treated wood to waterproof a below deck or is this for only actual existing roofs? Will this withstand snow and snow removal with a plastic shovel? Is this something my contractor can purchase and install?
1) You can install this over or under pressure treated wood
2) It will withstand snow / ice and you can clean it with plastic shovel.
3) You contractor must be approved by IB to buy and install this product … so most likely he CANNOT buy / install it now (IB is pretty picky about who they approve)
I’m looking to install a flat roof on a section that is a right triangular shape (10’x26′ = 130SF). The residence is in Rochester, NY. Looks like you are just in New England. If correct, can I install your system myself? I am the residence owner, fairly experienced with renovations and new construction (journeyman level skills), including work as a roofer while in college.
Also wonder about mounting the railing posts on the sides of the deck structure, thus avoiding any penetrations to the surface material. Pls comment on that idea.
Were you able to do this project? I too reside in Rochester, NY and I want to replace the flat section of my roof with an IB roof. I just have not been able to find any companies locally that work with this material. If you have any additional information, could you send it this way?

Good luck, Leo
Sorry for late reply, but I hope this helps.
You can install this product yourself with some practice first. BUT … you can’t buy it as a homeowners. So your options are to go to local roofing supply and buying other PVC material … most likely you will find Carlisle or Versico that you as homeowner (or contractor friend, or pretend to be contractor) will help you buy.
RAILINGS: Putting railing on the sides is wise. Waterproofing penetrations without proper skill and proper flashing accessories can be a nightmare – the fewer penetrations, the better.
You can do mechanically attached system – just make sure you mark your deck rafters and place all screws BETWEEN those marked lines, not under.
Also, here is local IB Roof rep’s info – he will connect you with local approved contractors if you decide to hire a roofer instead of DIY.
