When it comes to flat roofs, or roofs with minimal pitch, torch down roofing is the one more commonly used. Torch Down roofing is a rolled roofing product consisting of a non-woven polyester mat and a membrane embedded in a thick asphalt layer. The material is strong, durable, and weighs less than two pounds per square foot. It also comes in two different types of sheets: smooth and granulated. The granulated sheets come in different colors that reflect the sun’s rays, keeping your home cooler and reducing your energy bills.
