Importance of Coverage: Ensuring Adequate Roof Protection

When planning a roofing project, calculating the total coverage needed is crucial for ensuring your roof is adequately protected. This calculation hinges on the weight per square of the shingles, which represents the weight per 100 square feet of coverage.

Why Coverage Matters:

A properly covered roof is essential for protecting your home from the elements. Insufficient coverage can leave gaps or weak spots, compromising the roof’s integrity and exposing it to water damage, wind damage, and other hazards. By accurately calculating the coverage, you can ensure that every inch of your roof is shielded from the elements.

Determining Coverage:

To calculate the coverage, you need to know the area of your roof in square feet. This can be determined by measuring the length and width of each roof section and multiplying the values to find the individual areas. Summing up these individual areas will give you the total roof area.

Once you have the total roof area, you can determine the number of squares of shingles needed by dividing the total area by 100. For example, if your roof area is 2,500 square feet, you will need 25 squares of shingles (2,500 ÷ 100 = 25).

Using Weight per Square:

The weight per square of the shingles is crucial in determining the total coverage. Heavier shingles cover more area per square than lighter shingles. Therefore, if you choose heavier shingles, you will need fewer squares to cover the same area. Conversely, lighter shingles will require more squares to achieve adequate coverage.

By considering the weight per square, you can accurately estimate the number of squares needed to cover your roof and ensure optimal protection against the elements.

Types of Roofing Materials and Their Impact on Weight

When it comes to selecting the perfect roofing material for your home, weight is an important factor to consider.
