How is firestone modified bitumen roofing applied in asphalt or bitumen modification processes?

Firestone modified bitumen roofing is applied through a multi-step process. First, the surface is prepared by cleaning and priming. The modified bitumen sheets are then rolled out, overlapping edges for a secure seal. Heat is applied using a torch or hot air welder to activate the adhesive properties of the bitumen. This ensures a strong bond to the substrate. Finally, the seams are thoroughly sealed to enhance waterproofing and durability, providing long-lasting protection against the elements.
