Cost of flat roof decks
Why roof decks leak?
Most roof decks in existence today, use a flat roofing material that were created over a century ago and were not designed for use as roofing for residential homes and living area. Another reason is original design flaw implemented by architects and/or builders, who were not qualified in flat roofing and did not have appropriate roofing technology to use.
Ponding Water leaks:
Very often you can find ponding water accumulating on these deck roofs. Majority of flat roofing system existing today cannot sustain constant ponding water and as a result water enters your house, and destroys your possessions and property.
Wood Deck and Railing leaks:
Often there is a wood deck installed on top of a flat roof or some sort of a railing system. To make these railings securely attached to the roof, builders often create roof penetration for every railing post on the roof. The only way to “seal” these penetrations for most builders, is to use roof cement or pitch-pockets – both of these methods are considered unacceptable by the National Roofing Contractors Association (NRCA). Yet most builders don’t have the appropriate products, expertise and many times, don’t care enough to make these penetrations water-tight.
This, results in more leaks – usually these leaks don’t appear inside your home for years, but the hidden damages can cost thousands of dollars to fix. Water slowly enters your home and rots the beams and studs. While unnoticed for a long period of time, such leaks my sometimes result in partial or complete re-framing of your roof and/or support walls.

Details of roof deck construction using IB Membranes and DeckShield
IB DeckShield roof / deck assembly and installation:
DeckShield is easiest to use in new construction, however it can be easily adopted for retrofit use on existing homes. IB Deck Shield is installed as a fully-adhered application on top of Dens Deck – a fiber-cement type board that is 1/4 of an inch thick, or over plywood.
The surface for installing IB DeckShield must be clean, smooth and flat. That is why in some retrofit applications use of DeckShield may be difficult or impossible. When you have an uneven surface it is best to use the regular IB Roofing Membrane with a wooden deck over it. If you still want to use Deck Shield for a retrofit roof deck project, expect the additional costs of making your roof surface even.
DeckShield can be used for a small balcony as well as a large roof deck, and for everything in between. Hot-air welded seams make IB DeckShield a long-lasting waterproofing solution that is both eye-pleasing and safe to walk on when it is wet. Expect many compliments from your family and friends when they get to see your new roof patio with IB DeckShield.
DeckShield colors and texture:
DeckShield has a look and texture of tiny pebbles – something similar to a floor in a swimming pool. You can choose between two distinct colors – Tan and Grey – both look great and will compliment your home.
Since IB DeckShield is made from the same material as other IB membranes, it is easy to accommodate for any roof penetrations such as Railing System and Roof-Wall detail. This will ensure that your roof will be water-tight and you can take full advantage of your deck or patio once again and will not have to worry about leaks. Invite your friends and family for a cookout, enjoy a cocktail or watch the stars.

Hi Kieth,
Unfortunately we do not work in CA – we are located in Massachusetts. Otherwise I would be able to help you directly.
There are many IB contractors in Cali. You best bet is to call IB Roofs directly and they will put you in touch with local roofing contractors specializing in IB Roof installations. Call them – 800-426-1626.
Best of luck
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.
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 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.
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’m very interested in your product but reside in Texas.
Do you have contractors somewhere in Texas? If not what
would you advice? Need to finish flat deck ASAP.
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?
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.
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..
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.
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.
