I live in Texas. I’m having to replace the entire roof of my mother’s 60 year-old house, which has a flat-roofed addition that is almost that old. Two roofing contractors just said they would replace the ‘modified bitumen roof’ on the flat part. But the third quoted the following:
“Remove flat roof and replace with new BlueSkin base and new modified roll roofing top coat” and said he would be saving me money by not ‘hotmopping’ it. Does this seem to be a reasonable use of the BlueSkin product? I had never heard of BlueSkip before.

Hi..

HELP! I have a 12 year old flat roof deck with posts/railings that penetrate the membrane. When it was installed, the roofer ran the membrane up the posts for a few inches. It has seperated and the water has come inbetween the posts and the membrane and ruined the sub flooring.

I saw where you solved this problem by cutting holes for the posts in the membrane and then fitting a sleeve over the post and welding it.

I still cannot see how the membrane sleeve is attached to the post to prevent water leaking between the two.

How would you vent a sun room addition with this kind of roofing material when the roof pitch is 1/12 and all the rafters run perpendicular to the existing wall? A vented soffit would allow cold air to vent in, but it would cause condensation inside the room if that air wasn’t vented out once it hit the warmth of the interior wall. Don’t see how this would be handled with this kind of roof…We don’t want to spray foam insulation on the underside of the roof, but will be using baffles and R38 before installing T&G ceiling board. Any suggestions that help would be appreciated!

Hi Bill,

The IB DeckShield can be fully adhered, which is a typical installation type for it. I am unsure as to the surface that you have so your best bet would be to install 1/2 inch DensDeck (moisture resistant substrate for IB DeckShield) over the urethane/acrylic surface and install DeckShield over it.

You should start by locating local IB rep and also talking to Bryan in IB’s tech department – call IB Roofs at 800-426-1626 and there you can get a few local contractors and technical information.

Good luck.

Hi,We are planning to replace our flat roof using pvc/cpa 80 mil membrane.
We also have two decks 4ft by 16ft adjacent to the roof and maybe two inches above, that drain onto the roof through scuppers.

The decks, we have been told were originally coated with urethane and over the next 30 years acrylic, or maybe latex. We dont at this time suspect any rot in the plywood .

What I really want to know is :Can we get someone to fully adhere IB DECK textured PVC decking material to these decks? It seems to me that it would be good to do the decks and roof at the same time.Whqat surface preparation is needed?

Do you have a recomendation for suppliers or installers in the Seattle Wa Area 98103?

For Assembly Type 2: How are the compopsition boards attached? I’m concerned about penetrations into the IB system causing leaks into the room below.

I have a deck that is located over a bedroom. On occasion after a heavy snow or rain it will leak. Can you put me on to someone here in Philadlephia, Pennslyvania who can install IB DECK SHIELD.

Hi Enrique,

Yes, you can install IB Roof over Blue Skin – you will need a separation barrier thought. You can use 1/2 insulation, which we often use for our roof installations, or a Poly separation sheet. This way, if Blue Skin contains any asphalt-based products, it will not destroy the IB Membrane.

I recently added and addition to my house and added a flat deck over the kitchen, the deck was a last minute decision so it has no slope on it. The contractor recommended Blue skin, after reading about IB product I was wondering can I still use the IB product over the blue skin. I am hesitant on installing the sheet rock because I’m afraid the deck will leak. Any suggestions.
Please advice.
Enrique.
