Roofing Contractors In Delaware

One of the most important professionals in construction is the roofing contractor. In addition to consultation, they're also responsible for roofing installation and repair. Roofing contractors recommend area-specific roofing systems. Roofing contractors who work on commercial buildings use tar, gravel and rubber-based materials. Those who work residentially use asphalt and metal materials. Some climates also allow the use of cedar shank roofing. Waterproofing and winterizing roofs are also part of a roofing contractor's job description.

Licensing

In the state of Delaware, roofing contractors who bid for jobs over $50,000 must obtain a license. The license must be renewed annually and obtained from the Delaware Division of Revenue.
