Single Ply Roof Question
Hi,
We are trying to decide on roofing materials to have our roof
re-roofed. There is quite a bit of information on the pros and cons
of tar & gravel vs. foam in the archives, but there is not much out there
about single ply systems. These systems go by a variety of names,
such as IB, Duralast, and pvc coatings. (Duralast is a different
material than Durafoam. This is a PVC product- not a foam product.)
If any one has any experience, positive or negative with this type of
roof, I would love to hear about it. Also, I would like to know
companies that you used, and how long ago you had it installed. Please e-mail me directly at

Thanks for any information.

I am also looking for the answer.
Seems the most popular flat roof here is form roof.
any single ply roof owner here can post some comment and suggestion?
hi,
we actually had an ib roof installed in september of 2008. i am happy with it although we don't get the passive solar heat- but our house is soooooo much wamer than it was before that i am not complaining. (also, the roofer had recommended 2" of insulation, and my husband insisted on 3"- i am still curious how 2" would do.)
the roof has a lifetime warrenty for as long as we live in the house, and we were still able to hear the rain this winter, which is something i really wanted. you can find roofers from the ib roof website- they are in oregon. (just google ib roof.) otherwise, I have the name of two roofers - the one we used, and another that i heard about following hiring ours.
anyway, please let me know if you have any other questions.
cheers,
helen
I have a duralast and it's bulletproof, meaning it won't leak. Duralast claims to have never had a residential roof leak in their 30 years. white material reflects sun away, cooling your inside during the summer. probably need to clean it every other year with hose and mop.
Tar & gravel look the best, work great, and cost the least. light colored rocks work best for reflectivity. when my warranty expires on my duralast, I plan to install a tar and gravel roof. It's what was original.
I went with a TPO roof. Sierra Roofing did the install with 2'' of rigid foam insulation. The process wasn't 'easy' but the end result so far has been leak free. For this type of roof, they have to weld all seams together, which leaves the opportunity for tiny leaks. There is no way to check for this, other than to closely monitor the roof to make sure there are no leaks.
