What is your favorite flat roofing system? and why?
my favorite to install is tpo,and pvc. they're clean and easy to install. gaf freedom tpo is my fave. no glue, but i'm skeptical of it's longevity. of course coal tar pitch is the best, but as said cost, and lack of good installers has hurt this proven product. ive seen pitch roofs on chicago public schools that were 80+ years old and still in descent shape. now thats getting your moneys worth.:thumbup:
from an installers standpoint i like the s/a tpo, but personally would'nt put it on my house or busniess if i had one. i'd use something with a longer/ proven track record. they do install very fast though, but one thing that kinda slowed us was we were doing 2 layer iso w/ olybond. which can take awhile to rise if not in direct sunlight. plus crickets and saddles. did 1000's of sq. of these cookie cutter jobs for a national fitness center chain. the other PITA was they run all conduit for the building under the roof systems so 1st layer iso had alot of cuts. dont know the price difference between s/a and smooth back, but probably could make up for it in labor costs. i agree verisco glue is nice a little thinner, easier to spread.
At least that is what they say. :whistling:Duro- Last
