When choosing roofing materials, there seems to be an endless stream of choices on the market: asphalt, composites, metal, wood slats, rubber, and MSR laminated roofs. The roof pitch is one factor that determines which material to use, and a roof pitch calculator can help. Other factors also determine which type of roofing material you can use.

What is the Significance of the Roof Slope?

In short, roof slope is a measure of roof angle or slope, determined with the help of a roof pitch calculator. Since it is a crucial element of roof safety, there are good reasons to understand its use. The roof pitch (expressed as a ratio) is how many inches the roof rises for every 12 inches of width. Therefore, suppose the roof rises by 6 inches for every 12 inches of width. The roof slope can be expressed as a 6:12 slope.

Best Roof Spacing

The main reason for roof slope is to divert water. This is an important factor in ensuring proper drainage from the roof. You can try a roof slope calculator that helps determine the types of materials to be used in the roof system. The roof material is specially customized according to the roof slope. In addition, the roof slope determined by the roof pitch calculator affects the permeability of the roof, which is very important when you need to maintain the roof. The two main types of roof slope are low slope and high slope roofs. Before starting any roof construction, it is important to consider these factors.

Other Factors

Of course, roof slope is not the only factor in choosing a roofing material. The weight of the roof is another important factor. For example, green roofs and roofs with ballast can put considerable pressure on load-bearing components. Similarly, insulating the subfloor and roof can eliminate the need for certain roofing materials. Issues such as construction noise, fire hazards, smoke generation, and building passages are also very important.

Asphalt Shingles

For pitched roofs and ordinary roofs (starting from 4/12), asphalt shingles are an attractive choice. Asphalt is inexpensive. Asphalt shingles ensure that the roof is durable and has low maintenance costs. Synthetic wood and slate are strong and durable, and look the same as the natural materials they imitate. But for steep and ordinary roofs, shingles are best. They have been used for roofs for hundreds of years and are still an excellent choice for traditional roof slopes.

As for weight of the roofing material, every 100 square feet of material weighs at least 250 pounds. There are many grades of asphalt roof shingles, and the expected service life is 20 to 50 years, depending on the price.
