How can roll roofing be attached to the surface of the roof?

Roll roofing can be effectively attached to the surface of the roof using either a nailed or torched down method. When employing the nailed method, the rolls are secured directly to the roof deck with roofing nails, which helps prevent wind uplift and provides a secure bond. The torched down method involves using a torch to melt the granulated surface of the roll roofing, allowing it to adhere to the roofing substrate effectively. This method creates a strong bond, making it particularly useful for low-slope roofs.

The nailed and torched down techniques provide versatility and strength, accommodating various roofing conditions and ensuring a durable installation. These methods are widely accepted in roofing practices, making them reliable choices for securing roll roofing in place.
