Roofing is one of the most critical elements in building construction, both aesthetic and practical. A roof protects a structure from the elements while also serving various functional and aesthetic purposes. A roof is essentially the highest covering of a structure, consisting of all structures and materials needed to support it on top of the ground or uprights. Thus, a roof is often part of the architectural design, as well. This is why it is necessary to hire a reputable Roofing Company Metairie to ensure quality roof installation and maintenance.
The roof covering can either be a single layer or multi-layered. Single-layer roofs are typically corrugated fiberglass, with a foam backing that protects the corrugated fiberglass from moisture and the elements. Single-layered roofs are more stable but more expensive and time-consuming to install, as there are more layers to the roofing material. Multi-layer roofs, in comparison, are made of recycled or reclaimed lumber products, with wood shingles or shakes applied as the second layer. The final layer is a sealant or protective coating that protects the final layer from weathering, abrasion, and moisture.
Before discussing the function of each layer, we need to understand how the roofing system works. Underneath the roofing membrane (the first line of defense), there are support beams and rafters. The beams and rafters provide the foundation for the roofing system, holding everything together and helping to keep it in place. The first line of defense also includes flashings and downspouts, which channel debris away from home and towards the ground.
There are many different types of roofs. The most common form is flat or pitched roofs, which are typically used to conserve space and protect the home from direct sunlight. There are two slopes within the pitched roof: pitch roof and sloped roofs. The pitched roof has a single slope, whereas the sloped roof has two slopes with one pitch.
Another roofing underlayment option is a moisture barrier. Moisture is detrimental to the health of people, especially children. Therefore, a moisture barrier is essential. A moisture barrier consists of an extra layer of asphalt shingles or metal flashing. This additional layer helps to reduce moisture absorption and condensation by stopping the transfer of water vapor from the soil. It also helps to stop rainwater from running off the roof into the home.
In addition to moisture barriers, another roofing material used to safeguard the home is asphalt shingles. These asphalt shingles are fabricated in thin sheets to provide maximum protection from UV rays while adding visual appeal to the home. Traditionally, asphalt shingles were made from black volcanic ash. Today, however, they can be made from various materials, including slate and ceramic tiles. If you choose slate or ceramic tiles, they can also be installed on metal flashing and built into the roofing materials themselves.
On a related note, if your roof is not constructed from a solid material (such as slate), you may want to consider using synthetic underlayment. A synthetic underlayment layer can help protect the layers of asphalt or slate underneath it from wear and tear. In addition, when properly installed, the synthetic underlayment will help keep water away from these layers, which protects them from the elements (especially the hot sun). Without a synthetic layer, water would seep between the roofing shingles and the sub-base materials.
If your roof does not contain any of these materials, it would be wise to add them during construction. They will provide an additional barrier of protection that will help to keep out the weather. Some standard options include fireproofing tape, and roofing felt paper, and a variety of synthetic paints. Some companies even offer a full range of roofing materials, which will allow you to create a truly custom look that’s sure to please.
