Many roofing companies provide a number of services, including roof repair and installation. They also offer maintenance services like roof cleaning and re-coating. These are great options for homeowners who want to protect their homes from weather damage and improve their curb appeal.

A good roofing company has a clear project plan and a reasonable timeline for the work. They should also have a strong commitment to safety.

Roofing material

The roofing of a building is the first layer that protects it from sunlight, rain and snow. As such, the material used to cover the roof is subjected to constant exposure and must be durable. The type of roofing material that is selected can make a huge difference in the lifespan and performance of a roof. The most popular roofing materials are asphalt shingles and metal. Other types of roofing include rolled roofing, membrane roofing and flat roofing.

Rolled roofing consists of large rolls of asphalt material topped with mineral granules. It is affordable and is well-suited for low-incline roofs. However, it should not be hammered onto flat roofs, as this may cause water leaks.

Membrane roofing is another affordable option that can be applied to low-slope roofs. It is available in a variety of waterproof materials including EPDM, rubber or thermo-polyolefin (TPO). These materials are also durable and can withstand ozone and ultraviolet radiation. They can be loose laid or fully adhered to nailable or nonnailable decks. The seams are welded or heat-sealed.

Roofing installation

Whether you are building a new home or re-roofing your existing one, a roof installation is a complex job. It requires a lot of heavy lifting and climbing ladders. It’s also a dangerous undertaking and you should be fit enough to handle it. Most of the expense of roofing comes from labor and materials. During the roofing process, the contractor installs an underlayment, an adhesive starter strip, and a drip edge to defend against water intrusion. They may also install ridge vents to ventilate the attic space and exhaust hot air. They may also install other types of roof or gable vents, like sewer ventilation and curve vents for kitchen or bathroom spaces.
