The immediate benefits of having a flat roof system are its cost efficient use of available space. With a traditional roof, the angular slope means a great deal of unusable space goes between the ceiling and the surface of the roof. This is what we typically call the attic. On a flat roof you make the maximum use of space below the roof. Also because the roof is flat, you can use the space on top of the roof as well. Recreational roof gardens and other such things are common uses for the newfound space. It also makes the installation of solar panels much easier.

Flat roof systems are roofs that are built so that they are nearly flat. They are not completely flat; otherwise water would build up on the roof and would eventually start to get inside the building. Flat roofs are built with a slight incline. They are required to have at least a one-eighth-inch difference in height over each foot of the roof. There are five main types of flat roof systems. The best flat-roofing solutions will be Modified Bitumen.

A modified bitumen roof is a multiple-ply roof that is made with modified bituminous membranes, which are made out of a blend of asphalt and a polymer. This allows the asphalt to take on characteristics of the polymer, which is similar to materials used in single-ply roofs.

On residential low-slopes we use Mule Hide SBS Modified Self Adhered over new ply wood decking for small jobs. Other than that its cold process adhered modified all the way! We do small built up roofs using asphalt and coal tar at times when needed.

We Don't Do Many Commercial Jobs - But Roofed Residential

Flintlastic with Full Coverage Grace Ice & Water Shield?

Use of CertainTeed's Flintlastic SA NailBase in a self-adhering system permits complete mechanical attachment to nailable substrates, preserving the integrity of the substrate for future tear-offs and adding additional waterproofing performance capabilities to the overall system. Flintlastic SA NailBase also adds to the fire resistance of the roof system, enabling UL Listing of the roof system.

We use on flat shed dormers & porches, ect...

Outstanding Warranty Options

CertainTeed backs its commercial roofing systems with the confidence of three warranty choices!

Flintlastic is no good in the cold weather and not very good if you have a lot of flashing details. Its only advantage is it can be installed by shinglers for small stuff. Its basicly glorified roll roofing that is only intended to last 10 years max, although PolyGlass who invented the modified SA's has a whopping 15 year warranty.
Better to go with a nice one piece single ply.

Singly Ply - Rubber is the best for slow pitch we all know THAT!

The question is, when completing residential homes is the Single ply rubber roof installation an option for all roofing contractors?

As long as the budget is large enough we provide the fully adhered single ply 060 rubber roof application, as stated you cannot put the rubber down in the cold, so up in Maine we offer torch down, and Flintlastic as an option because you can use a torch to help activate the adhesive for the rolled roofing material. :thumbup:


Awesome.... Love The Roofing Convesations!

Massachusetts "Cape Cod area" is just as cold and windy as Maine and we install single ply ,EPDM rubber and PVC, IB Roof System's all year long. Of course there are tricks of the trade when working in any weather but why put a 10 year roofs with seams with is Timberline roof that should last at least 30 years ? IB Roof systems is the only one to offer the custumer a written lifetime residential warranty or a 25 year commercial warranty. They even have colored membrane. http://www.ibroof.com/IBinfo/res_types.html

A Certainteed 3-ply flintlastic SA system is warranted for either 15 or 20 years. I forget off the top of my head because it was for sure 15 years on the 3-ply, but I heard rumor they upped it to 20 years in 2010.

I do agree it's better for small stuff. I also agree that single ply is my preferred membrane on typical larger roofs. I also agree it's not good in cold weather requiring at least 40 degrees farenheit or more. This means it can only be install 6-8 months out of the year around here.

It sucks on residential most single ply manufacturers don't want to get involved. I'd have set up an IB account long ago, but due to logistics we're just not a good match for their company. In other words, my other suppliers have cranes on their trucks, IB doesn't over here so for each job I'd have to rent a crane to get the materials on the roof.

hey Grumpy, you should give IB a chance. They deliver to my shop or to the job and I have it all craned up with the ISO board. I have to buy that seperate. Bradco or Beacan or maybee ABC would have no problem with this typicly. another option on small jobs is to put the rolls of IB up with a power ladder.

There are a few old school roofers on here that like BUR roofing systems. I am also one of them, 4ply capsheet is standard but we install as many plies as needed cap it off with aggragate, SBS, Cool roof caps, ect. The key to this system is a great hot crew that works as a finely oiled machine From the Firstman down to the kettle man. We are the goto Co. when when it comes to BUR systems Around here everyone else does single ply. BUR to me is still the best system.
