How To Choose A Roofing Contractor

A roof is more than just a covering for a building; it protects against weather and provides structural support. Depending on the material and its location, it may also add beauty to a home or enhance its value. The roof is usually the least accessible part of a house for maintenance, but its condition has a significant impact on how well a structure functions and looks. Whether a new roof is being constructed or an old one repaired, there are a variety of materials from which to choose.

Traditionally, Nashville Roofer have been made from wood or shingles. These materials can still be found, but homeowners now have more options, including metal and clay tile roofing. These materials cost more than shingles, but they typically last longer and can help lower energy bills.

Before hiring a roofer, ask to see examples of his work. Also, check for insurance and workers’ compensation. Make sure the contractor is licensed and insured for general liability, as well as any specific types of roof work. It’s especially important to hire an experienced roofer if you’re working with a unique roofing material, such as standing seam metal or slate.

A roof’s surface is protected by underlayment, a water-resistant paper that goes over the plywood sheathing. It’s then covered by a waterproof membrane and a vapor barrier, which prevents the buildup of moisture that can damage the roof. The vapor barrier can be made from plastic sheeting, or it can be a thick layer of foam insulation called high-density spray polyurethane foam (SPF).

Other roofing materials include corrugated galvanized metal, EPDM rubber, TPO, tin, copper, and slate. Some of these materials require a steep pitch to be effective; others can be used on flat or low-sloped roofs and provide adequate protection in dry climates without the need for a sloping roof.

Many roof problems are caused by poorly installed flashing, which is pieces of metal or other material that seal the joints where the roof meets walls, chimneys, and plumbing vents. Look for rust, cracks, or missing or pulled nails that can let water in. If the flashing is damaged, a roofer can repair or replace it.

Solar roofing options are gaining popularity as a way to save money on electricity while reducing carbon emissions. Many manufacturers have adapted traditional asphalt shingle styles to incorporate photovoltaic cells, and there are now federal tax credits for solar roofing that can offset installation costs. Check with your state and local governments for details.
