Commercial roofs differ significantly from residential roofs. Therefore, if you have a commercial building, you should know a few things about commercial roofing St Louis before you repair or install a new roof.
Roof Size
Commercial roofs are typically much larger than residential roofs, producing greater risks of leaks and damage. Due to the expense of a larger roof, many may seek out cheaper materials, but this can be a big mistake. You want a roof that is durable and will last a long time, not one that covers the roof decking and is easier on your pocket book.
Materials
Commercial roofs are typically composed of asphalt , metal or green roofing materials, such as plants. In addition, your roof may have a membrane system. These systems are common on flat roofs because they are durable and save energy. In addition, your roof may have a single-ply or build-up roofing membrane, and if the building has been added to over the years, it may have a combination of materials. Before any repairs or replacements can be made, you need to determine your roof’s composition.
Longevity
Even if two buildings are roofed with the same materials, their lifespans may differ significantly based on the building’s location and roof characteristics. Roofing typically lasts 10-50 years based on their materials. For example, single-ply roofs typically last 15-30 years. Climate and weather also affect a roof’s lifespan. Seasonal maintenance can increase the lifespan of your commercial roof.
Damages
Commercial roofs are most commonly damaged by the sun.
