We removed the old roof system, modified bitumen, down to the original deck substrate. Rotted wood and comprised framework underneath, preparing the decking was the most difficult aspect to the new roof system. Once all repairs were made to the deck, a layer of vapor barrier was install over the entire substrate. We then install a tapered roof insulation system to the entire roof. The drainage flows top to bottom, so the top of the roof has 8" thick insulation tapering down to .5" at the bottom. Positive drainage is vital to the longevity and water shedding ability of any roof system. Next, a layer of .60 mil GAF EverGuard TPO membrane was installed over the entire roof. All seams were heat wielded and probed afterwards to check for wield quality.
