When people talk about roofs, they usually refer to the shingles or the materials that cover the whole structure. This is because they’re the only visible parts of the roof. However, a roofing system actually consists of several components that must work together to provide the necessary protection to your home.

Each of these components is important and any weakness or damage to any of them could affect the whole structure. If you want the your roof to hold out for as long as it can, you must make sure that each part of the system is in excellent condition. Otherwise, your roof may not be able to withstand the adverse effects of harsh weather conditions.

Among the most important components of a roofing system are the roof deck and rafters. The roof deck is directly under the outermost layer of the roof, while the rafters serve as the foundation for the roofing materials and support the roof deck. They must be solid, stable, and free from moisture damage and mold formation.

Next comes the underlayment or the sub-roof system, which is consisted of materials used to protect the underlying wood from rotting ...
... and keeping water and other elements from backing up under the shingles. These are installed under the shingles and on top of the roof deck. A roofing system must also have a ventilation to regulate the proper balance of intake and exhaust to work efficiently.

Other important roofing components include the fascia, downpipe, soffit, and gutters NJ contractors install in the system. A fascia is a trim used to cover the rafter end of eaves and gables, while a downpipe is a conduit to carry water from the gutters. A soffit covers the area between the end of the eaves and the house, while gutters are channels which collect and divert water from the roof.

New Jersey roofers or contractors also provide flashings for the roof system they install. They are designed to prevent the water from seeping into intersections in the roof like vent pipes, chimneys, valleys and joints at vertical walls. These include roof edge flashings, step flashings, counter flashings, wall flashing and stack flashings, each having specific functions to protect the roofing system.

The most visible parts of the roofing system are shingles. They come in various types of materials which any roofer NJ clients prefer can provide their customers. However, you should remember that the materials and roofing system is only as good as the people who install them. Hence, you must be careful when hiring contractors.
