Common questions
How long does torch down last
A two ply torch down roof installed well gives fifteen to twenty five years in Los Angeles.
Can I coat a wet flat roof
No. A coating over trapped water blisters and peels. The wet layer has to come out first.
Is TPO better than torch down
TPO runs cooler and weighs less. Torch down handles foot traffic and heavy patio use better. The right pick depends on how the roof gets used.
