From hot desert locations to beachfront communities, regional weather directly affects all roofing materials. When Chesapeake roofers evaluate a property for shingle replacement, they cannot use a universal product for all clients. They must analyze both the property and yearly weather patterns to select certain materials that stand the test of time.

A specific shingle feature that contractors must analyze is wind resistance. Certain areas, especially along coastlines, have strong winds throughout the year. Some of these winds can gust more than 50 miles per hour. To avoid any extreme damage across the rooftop, contractors use shingles rated for the average wind gusts in the region. These shingles are designed and tested for their rating range and must pass all standard evaluations before being sold to contractors.

Although contractors select shingles based on the proper wind resistance values, tab lifting can still be an issue. For areas with volatile winds, roofers often use adhesives to secure shingle tabs even further. They'll add roofing cement to tab edges and press them down as each row or course is created. It would take considerable force to lift any shingles up and cause moisture damage in the home. Only a major weather event could lift or pull these shingles from the surface.

Underneath those strong shingles is underlayment.

Reputable contractors suggest underlayment for all roofing installations, but it must be added correctly. For windy and rainy areas, underlayment should have several inches of overlap to protect the roof decking below. Contractors who butt underlayment edges against each other are creating seams prone to moisture seepage. Although shingles are the first line of defense against moisture problems, underlayment is a second, critical layer that must be overlapped precisely.

With underlayment laid out and shingles about to be installed, there's another feature besides wind resistance that must be examined. Fire resistance is inherent to material construction. Organic or wood mat shingles are prone to catching fire. If an area has fire potential, contractors normally suggest fiberglass replacement shingles. These shingles can ward off some heat and sparks, allowing the structure to stand tall when fire threat is near. No roofing material is completely fire resistant, however.

If homeowners hear contractors discussing class rating designations, material selections are being carefully analyzed. Only reputable and knowledgeable contractors take the time to look at all material features, including ratings based on extreme conditions. With the right class rating chosen for a property, homeowners can be confident that the material is properly matched to the structure.
