Aside from protecting your home against the elements, such as wind, heat, rain and debris, your roofing system should also be able to handle strong pressure that’s forced on it from all directions. There are some roofs that handle loads better than others. In today’s blog post, the top roof replacement and asphalt shingles installation expert, Dior Construction, shares three different kinds of roofing loads and how it affects your roof.
When a temporary weight is added onto your roof, this is what’s referred to as a “live load”. A few examples of what can be considered as a live load is the roofing crew, their equipment, and the materials that they bring with them. Any roofing system should be able to support both dead and live load at any point in time. Additionally, not only should it be able to support its own weight, but an expected live load as well.
When strong gusts of wind hit the side of a home or building, the wind exerts pressure along the wall. After it hits your wall, the wind also blows upward towards your roof. Your residential roofing contractor would tell you that your roofing system should be able to withstand this load, especially if you live in an area with high winds. Thankfully, most of the uplift load can be negated as long as your roof has enough dead load to counter it.
The dead load refers to the actual weight of your roofing structure, along with the support structure and other permanent components of the property. This also includes the weight of the construction materials, such as the shingles. All residential roofs are designed to support their own weight. The roof load is measured using pounds per square foot. To put this into perspective, the dead load of a typical asphalt shingle roof with wood frames is normally around 15 pounds per square foot.
