What technical requirements define modified bitumen roof repair for asphalt or bitumen modification?
Modified bitumen roof repair requires specific technical requirements to ensure durability and effectiveness. The surface must be clean and dry, free from debris and contaminants. The repair material should match the existing membrane’s type, either APP or SBS modified bitumen. Proper adhesion is critical, necessitating the use of compatible primers and adhesives. Additionally, repairs should be applied at appropriate temperatures to ensure optimal bonding and flexibility. Finally, all seams and edges must be sealed to prevent water infiltration.
