CONTAMINATED ROOF MEMBRANE
FIRE HAZARD CONSIDERATIONS The National Fire Protection Association requires roofs to be protected from fire hazards. Scheduled maintenance is an essential factor that promotes roof system longevity and protects the roof system from possible fire exposure. Chemical and animal fat contaminated areas should be restored to serviceability and a regularly scheduled preventive maintenance plan contracted to eliminate membrane failure and elements that cause roof fires. T&R Roofing Specialist Restores Roof Contamination | ||
All roofing systems unless specifically manufactured are susceptible to contamination. The typical contaminants are grease (animal fat content), refrigerant, and solvent based material. Membrane that has been subjected to prolonged exposure to contaminated material will gradually degrade until the membrane completely deteriorates. If the problem is identified in the early stages, membrane replacement will eliminate the problem. The cost to restore the damaged area can significantly increase if the contamination develops into a leak source. Once the membrane completely degrades the insulation and substrate can be affected, and all materials must be replaced to obtain a serviceable condition. Restorations must include bagging all materials that have come in contact with the contaminated material and removed from the roof for proper disposal. The roof must be cut out around the affected area and all material properly disposed of. The perimeters of the area must be cleaned thoroughly or primed whichever is specified. An overlay of membrane and reinforcement will eliminate projected problems. T&R Roofing Specialist promotes installation of a Grease Guard surround system to eliminate future exposure to contamination.
