Commercial Roofing 101

Updated: May 31, 2023

Commercial roofing is an important part of protecting the assets of your business, but it can be difficult to choose which type of roofing works best for your business. Each commercial roofing type has its own strengths and weaknesses, so this article will help you understand what makes each type different from the others and how to decide which one would be best for your business’s specific needs.

Commercial Roof Materials

There are several different types of commercial roof materials, including clay tile, concrete tile, rubberized membrane, metal, single-ply membrane, double-ply membrane and shingle. The most common choice is asphalt shingles due to their low price point. However, for long-term use or high-traffic areas of your building—such as near loading docks or entrances—metal roofs may be a better option.

While asphalt shingles are affordable, they don’t last nearly as long as metal roofs. Asphalt shingles have a lifespan of only 15 to 20 years. Metal roofs are able to withstand up to 110 mph winds, which makes them ideal for areas where high winds occur frequently. They typically come with a 30-year warranty on materials and installation.

Commercial Roof Cost

The cost of commercial roof installations can vary greatly based on your roof’s construction, complexity, your location, labor costs and a variety of other factors. You will need to factor in replacement materials and repairs down the road. To help offset these expenses over time, it is usually best to choose a high-quality roof that will last for many years without needing extensive repairs or replacements.

Regular Commercial Roof Maintenance

Taking care of your commercial roof is critical to its longevity. Think about it, roofs are one of a building’s most important structural components, not to mention that they’re also meant to provide protection from unpredictable weather. But without proper maintenance, your roof can quickly become damaged and run into major issues. If you want to keep your building in top shape throughout its lifetime, regular maintenance is crucial!

If you are ever unsure if you need maintenance ask yourself: Is there any damage or wear? Are there any leaks? What kind of repairs need to be made? Once you have all these answers, you can take action and make sure your roof stays protected for years to come.
