When it’s time to buy a new roof, a lot needs to be considered. It is a huge investment, after all. When discussing a job with roofing contractors in Louisville KY area, many things should be kept in mind. What exactly do you need to know about roofing? What components make up a quality, lasting roofing system? Most common steep slope roofs have several key components.

Most people think about the actual roof covering. This can come in the form of shingles, or even tile or metal. It is placed over the top of an underlayment and acts to keep the sheathing dry. Sheathing is simply the boards or metal which are used to cover the rafters of building’s roof. The roof itself is made of structures called rafters which are connected by angular trusses.

The most common roof covering in the United States are asphalt shingle. The asphalt is mixed with either fiberglass or organic materials for reinforcement. The fiberglass option is the most popular of the two, although organic wood felt asphalt shingles have been around for a long time. These consist of the felt layer that is then soaked in asphalt. Mineral bits coat the top of the shingles. One of the reasons that fiberglass is preferred is due to fire rating, which is Class A-;the most fire resistant. Organic shingles are rated at a C-;the least fire resistant.

Wood shingles made of roughhewn cedar or southern pine, offer great rustic appeal. However, some building codes discourage or prohibit their use due to fire resistance concerns. Most rank at C or have no rating at all. Slate, on the other hand, is incredibly protective and long-lasting. Yet this comes a much steeper price than other options.

Flashing can cause issues if it is missing or incorrectly installed. This consists of metal or plastic that is placed at joints on a roof in order to prevent water from seeping under and damaging the roof’s structure. A roof needs to be designed to allow for water to properly drain away. Gutters are actually an important part of the roofing system that many people don’t consider as such. roofing contractors services can help one decide what options are the best.
