There are several types of roofing techniques including the pitched or gabled roof and the low sloped roof. The latter is frequently known as a flat roof, but this is a misnomer because a roof that is actually flat would not shed water properly. Low-sloped roofs are common on many commercial buildings because they can cover larger areas more easily than a steeply pitched roof. The typical method used for Commercial Roofing in Northern Virginia is BUR (built-up roofing) and is made with multiple layers of water resistant membrane and asphalt placed over the decking. BUR roofing is then covered with an aggregate such as gravel. The membrane is usually roofing felt, but other options are possible.
There are many benefits to the use of BUR. First, this method of roofing is budget friendly compared to most other options. Second, BUR is easy to repair because smaller issues can usually be patched while larger problems are often fixed by installing another layer. Of course, there is a limit to how many layers that a BUR system can have. This will depend on the supporting structure and the quality of the decking material. Most decking will be an engineered wood such as OSB (oriented strand board) or plywood, although some roofs may use steel. The support of these engineered materials varies by quality and thickness. Plywood is the preferred option because it survives exposure to moisture better than OSB.
Alternatives for Commercial Roofing in Northern Virginia include various membranes such as TPO (thermoplastic polyolefin) and EPDM (ethylene propylene diene terpolymer) or the use of steel panels. TPO is an excellent polymer for large roofs because it is placed in long strips. This application method makes it easier to secure the seams. TPO seams are joined using automated welding tools with small joints and roofing details being sealed by hand. EPDM is a synthetic rubber that works well for specific environments. This roofing membrane is often coated so it reflects sunlight, which can be useful in lowering indoor temperatures. EPDM will require an experienced installer because the material has been known to shrink, but correctly installing it should avoid any potential issues.
