This twenty year old Modified Bitumen Roof is over a wood processing plant so as you might imagine a leaking roof is not only inconvenient, its also costly due to down time and ruined product. The first thing we did was power-wash the entire surface with over 3,000 psi to ensure the roofing system would adhere to the aged roofing material.
At that point the waterproofing stage began. We then addressed every seam and penetration with a polyester fabric and a silicone sealant. We sprayed an initial layer of silicone sealer onto each seam, then laid fabric into the silicone coating, and finally sprayed another layer of silicone to ensure a seamless seal. The same process was done around each penetration on the roof. The next step was to apply the fabric and silicone roof sealer to larger areas in the field of the roof since this particular roof had aged to the point where leaks were throughout the entire surface.
After the fabric was installed in all the areas of concern, the entire roof was sprayed with two more coats of liquid applied silicone to form a seamless elastomeric membrane over the entire roof area.
