It’s not easy to decide what type of flat roof installation is best for your commercial or residential building, but Rooging101 can navigate you through the process. Some flat roofing treatments are equally suitable for new construction or re-roofing applications, while others are not. Some flat roofing materials offer advantages in large-scale commercial projects but cause problems with smaller residential roofs. Energy performance, maintenance requirements, and installation costs are all factors to consider when choosing a flat roofing material. Roofing101 can help you choose the flat roof option that’s right for you!
Flat Roof Installation
- Built-Up Roofing (BUR). This “old-school” flat roof installation involves the application of roofing felt (tar paper) and asphalt-based roofing tar, often in multiple layers. A top layer of gravel or a reflective coating is required to cut down on heat gain and improve durability. Maintenance and repair work usually call for more felt and coating layers to be applied.
- Modified Bitumen. This flat roof installation option works well on residential & small-scale commercial flat roofs. Because it comes in 3-ft.wide rolls, modified bitumen roofing is easy to handle and apply. The roof surface gets a reflective coating for durability and reduced heat absorption.
- EPDM Roofing. Despite its exotic chemical derivation, ethylene propylene diene monomer has the look and feel of an everyday rubber inner tube. An EPDM roof can easily last 20 years with minimal maintenance, but its dark tone absorbs a tremendous amount of heat. To prolong the life of this single-ply roof and reduce cooling costs, a reflective top coating is essential.
- PVC Roofing. This single-ply roofing material is made from polyvinyl chloride, the same high-performance plastic used in plumbing pipes. Like EPDM, PVC is most frequently used on larger commercial roofing jobs. PVC roofing is naturally white, giving it excellent heat-reflective qualities without any coating or extra treatment.
- TPO Roofing. TPO is short for thermo-plastic olephine, the chemical composition of this fabric-like roofing material. The material comes in rolls of different sizes, making it suitable for a variety of flat roof projects. TPO usually costs less than EPDM or PVC, it doesn’t yet have the same track record of proven performance.
- Spray Polyurethane Foam (SPF). This option combines roofing, flashing & insulation. Instead of tearing off an old flat roof, SPF technology enables a contractor to spray on a continuous layer of high-density foam that seals leaks and bridges gaps to form a waterproof barrier, even around roof penetrations like vent stacks. The cured foam layer has good insulation value, helping to reduce heating and cooling costs.
