In most cases, a residential roof and a commercial one will vary in style and construction techniques. For example, the residential roof will typically be made from asphalt shingles placed over a membrane such as roofing felt which is lain over wooden decking. Commercial structures often have flat or low-sloped roofs covered in one of several possible options. The most common method used by commercial Roofers in Grove City Ohio is BUR or built up roofing. BUR is multiple layers of bitumen and membrane that is topped with a layer of aggregate such as gravel. It can be as thin as three layers and is easily repaired by installing new layers. However, BUR may need a lot of maintenance so alternatives such as polymer sheets exist.
One polymer option is TPO (thermoplastic polyolefin) and is applied in long sheets. Each sheet is rolled into place and pulled tight. Seams between the sheets are then sealed with the robotic tool to provide a strong, durable seal. TPO is easy to patch when damage occurs and a great choice for the replacement of BUR. Alternately, a PVC (polyvinyl chloride) sheet may be used, but TPO tends to be preferred solution. Another possible roofing solution is EPDM (ethylene propylene diene monomer) which is a synthetic rubber. Like TPO, it is applied in sheets, but it requires different methods for repair.
Roofers in Grove City Ohio may also recommend the use of a modified bitumen covering. This membrane comes in rolls and is an altered form of asphalt. That is, the asphalt flux has an additive that provides additional properties. There are three common types and they come in one, two or three ply systems. The first uses APP or Atactic Polypropylene as the modifier. The second uses Styrene Butadiene Styrene (SBS) and the third uses coal tar. The modifiers are introduced into the asphalt to add plasticity to the roofing materials and this improves their reliability. The actual type in use will depend on the building, its size and various other factors. APP products have a polyester mat for structure while SBS variants can use polyester, fiberglass or both.
