Unlike most residential roofing projects, repairing the roof of a commercial building can be an enormous task. It usually requires commercial roofing contractors Lynnwood WA, with the ability to handle hot materials and carrying them to fairly high buildings. This assumes that the roof is a flat or low-sloped roof which many commercial buildings are. This type of roof uses a membrane such as roofing felt or PVC (Polyvinyl Chloride) placed over the decking as the first layer of protection. The next is a layer of asphalt and then a layer of aggregate to keep things in place. This sort of roof is also known as BUR (Built-Up Roofing). One reason for this is the fact that the roof can have additional layers added as future repairs require it. The maximum will depend on the materials that hold the roof in place.
There are a few alternatives that are recommended by many commercial roofing contractors Lynnwood WA, such as North Creek Roofing. These include the TPO (Thermoplastic Polyolefin) roof, the PVC roof and a rubber based membrane known as EPDM (Ethylene Propylene Diene Terpolymer) which is often used for smaller buildings where shrinkage is not too much of a problem. TPO and PVC polymers are useful products when spanning large roofs because the material is welded together using robotic tools on site. This means a better fit and the capability of making adjustments where required. Benefits of these types of membranes include longer life between repairs and no need to refresh the asphalt like the BUR method requires.
Damage to a commercial roof can result in a lot of complications. For example, some buildings place a lot of critical wiring in the ceilings. If water is allowed to access these wires, it could result in short circuits, loss of vital data and other serious issues. Even if the business uses a smaller building, a damaged roof can create havoc. No business wants to expose customers to rain while they are inside the building. This is where expert service really pays off. A quick fix can often remedy the leak until a more serious effort can be made. In the case of BUR, the fix may be as simple as a little tar to seal off a crack. For more information, Visit Website here.
