Our rubber roof system utilizes a Mulehide EPDM rubber membrane installed using the total-adhered application method. First, a 1/2" dense insulation board is screwed onto the roof deck. Next, the rubber is layed out and put into place. Then the membrane is folded back, and both the roof and membrane are glued 100%. Finally, the units and stacks are flashed around and the edge is secured. Throughout the whole process we use certified Mulehide products done in accordance with Mulehide specifications.
