Did You Know?
1. Rolled roofs, also known as mineral surfaced rolls, were initially developed in the early 1900s as a more affordable roofing option for low-slope buildings.
2. One of the key components of a rolled roof is the granule surface layer, which provides durability and protection from the sun’s UV rays. These granules are made of crushed rock, ceramic-coated minerals, or even colored glass.
3. Rolled roofs are primarily used on structures with low-slope or flat roofs, such as sheds, garages, or mobile homes. They are less commonly found on residential houses with steeper roofs.
4. While traditional rolled roofs are typically made of asphalt or bitumen, there are variants available that use synthetic materials like rubber or thermoplastic, offering enhanced performance and longevity.
5. Rolled roofs can be installed with a torch-down method, where the rolls are adhered to the roof using a propane torch, or using a cold adhesive method, which avoids the use of open flames and can be a safer option.
