Flat roof replacement gravel tar or membrane ?

Post by phantomvs » Fri Feb 08, 2019 4:50 am

Hi guys !
My flat roof which is presently tar and gravel started leaking.
I am not sure when it was done exactly but it's over 13 yrs old that's when I bought the house.
I plan on replacing it and not sure if I should go with tar and gravel or a membrane like TPO or EPDM ?
Any experience with these type of roofs in a cold climate ?
Thanks !

My experience with flat roofs is beyond out of date, sorry.

I also am not really in the flat roof loop. I would contact companies in the different fields you mentioned and get some quotes and opinions.

I live in Arizona and would definitely recommend a membrane roof over tar and gravel. Most membrane systems here require either a white or tan reflective coating every 5 years or so. If you go with this method, make sure that you reseal all of the roof penetrations with an approved mastic and I get best results if I put down something like Laticrete Waterproofing Membrane Fabric as extra security.
Good luck!

I know that EPDM roofs are used here in Saskatchewan but I do not know the specifics of them. We are cold climate though!
