If your commercial building has a flat roof, the day will come when you need the services of a flat roof repair contractor. In selecting a contractor, it’s important to choose one that has expertise in the type of roof you have. Hiring a shingle roofer who mainly services homes can be disastrous, as roofing a commercial building is a completely different ballgame.
Types of Flat Roofs
Flat commercial roofs are a popular choice for commercial and residential buildings, and there are various types of flat roof systems to choose from.
One of the most common types of flat roofs is built-up roofing, or BUR. For a BUR system, the finished membrane generally consists of alternating layers of bitumen (usually asphalt, coal tar or cold-applied adhesive) and reinforcing fabrics. Surfacings used include aggregate like gravel, slag or mineral granules; mineral-surfaced or glass-fiber cap sheets; hot asphalt mopped over the roof surface; elastomeric coatings; or aluminum coatings. Asphalt BUR is the most common type and is made up of multiple layers of asphalt and reinforcing plies, forming a redundancy of waterproofing layers.
Single-ply membranes are another common flat roof type. They are factory manufactured and usually classified as either thermoset (EPDM) or thermoplastic (TPO or PVC). The main difference is thermoset materials become irreversibly solidified following heating, while thermoplastic materials can be repeatedly softened and hardened through heating and cooling.
Modified bitumen is also a common choice for flat roofing. It features polymer-modified membranes that are composed of reinforcing fabrics that serve as carriers for hot polymer-modified bitumen while it is transformed into a roll material. Similar to BUR membranes, the membrane of a modified bitumen roof is composed of multiple layers. This type of roof system is generally installed as a two-ply system, and it is almost always fully adhered. The surfacings of modified bitumen membranes include aggregate surfacing, metal foil-laminate surfacing, mineral surfacing and smooth liquid-applied surfacing.
