The typical roof on a commercial structure uses the BUR (Built-Up Roofing) method to protect the building. This budget roofing is fine for certain types of roofs, but it isn’t the only type of Roof Installation available. For instance, a commercial roof can be covered with several types of membranes. The first is the PVC (Polyvinyl Chloride) membrane. This covering is reasonably easy to install and provides excellent coverage. The material is placed so that a robotic welder can seal the seams quickly and accurately. This reduces the chances of roof failure in heavy winds.A similar product is TPO, which stands for Thermoplastic Polyolefin. This membrane is also welded together for durable seams. The difference is in the way the plastics handle the elements. TPO may function better in areas where PVC degrades too quickly. Alternately, the roof may be covered with EPDM (ethylene propylene diene terpolymer), a synthetic rubber membrane. One benefit of this roofing option is a tight membrane as the rubber is stretched over the frame.The other type of commercial roof uses the pitched or gabled style of roofing. That is, the roof is angled so that rain, snow or ice can easily slide off. Pitched roofs can be made from sheets of steel or they may be covered in the typical asphalt shingles. The downside to many pitched roofs is the low-quality materials that are available. The use of budget shingles may seem attractive until the roof fails and the repair must be done again. In this case, a new Roof Installation may be called for.Replacing a roof can be a challenging task. The contractor must first remove any old material that might be in the way. Old asphalt can be difficult to clean up after the fact, so it is important that the contractor keeps the work area clean. To properly remove the old roof, the contractor will need to pull off both shingles and roll roofing. The latter is an asphalt coated felt or paper used for additional protection. This should expose any decking for inspection or repair. If the roof is beginning to leak or happens to show signs of age, contact the experts at and learn what options are available.
