Some flat roof replacement options include built-up roofing, single-layer membrane roofing and modified bitumen roofing. These materials are ideal for flat and low-slope roofs in both commercial and residential settings.Continue Reading
Single-layer membrane roofing is one of the more popular options for flat roofs, working well for residential and commercial buildings. Single-layer membrane roofing is usually done with EPDM, which is a synthetic rubber. However, there are also other materials, including neoprene, PVC, polymer-modified bitumens and chlorinated polyethylene with chlorosulfonated polyethylene sheets.
Built-up roofing is one of the oldest types of flat roofing materials, though it is still seen on some homes and businesses. It works for flat and low pitch roofs that can’t handle shingles or other materials. There are multiple layers of material in this type of roof, which are applied with a hot mop. It typically includes either coal tar pitch blends or hot applied asphalt with roof felt.
Modified bitumen roofing is typically used more often than built-up roofing, as it was originally created to replace it. It is similar to built-up roofing, but it has extra polymer-reinforced layers to provide more stability and a longer-lasting flat roof. There are different methods of installation, including self-adhered, hot applied, cold applied and torch applied.Learn more about Home Maintenance
