I can't find a clear answer so far for this:
Is 3' wide peel and seal suitable as a long term finish flat roof material?
The roof is about a 10x10 front porch. The work is neat and all that, but I know I've used it before and it does not always fill the bill as it were. It was also used as a flashing in that area. Overlaid of course.

Jeff, not sure what product your looking at but most of the peel and seal products are designed as an under lament and will not hold up well over time.

These products are usually thinner than a permanent roof covering. Do you have any picture's?

I've been told that if it has a granular coating, it's suitable for exposure as a roof material.

Is the membrane possibly GenFlex TPO, white in color?

Most peel n stick membranes are designed for waterproofing under a tile or concrete type roof. They have a 3-5 days max UV exposure limit before needing to be covered. This inc brands like Protectowrap etc.

The only way to know for sure is to know the manufacturer, have the installation instructions, and it product approval - if those things say yes it is okay for an exposed roof covering, then it is, however, if they do not say that, then no it is not.

It may also have moderate term UV exposure limits (up to 6 months) or short term UV exposure limits (I haven't seen any which state 3-5 days, but there may be some).
