Not all roofs are created equal, and this is especially true when comparing commercial flat roofs to the type of sloped or pitched roofs found in residential roofing. Flat roofs are the most common roofs found in industrial and commercial buildings. Even if you know everything there is to know about how a sloped residential roof works, a flat roof is fundamentally different and has completely different needs. Rather than asphalt shingles, flat roofs typically use either tar and gravel or protective membranes to prevent water and air infiltration.
Our commercial roof repair contractors at A-Plus Roofing in Burnsville specialize in installing and maintaining commercial flat roof membranes. In this post, we’ll discuss some of the most common causes of commercial roof damage, and how we can help protect your roof when they occur.
1. Inadequate Maintenance
The main reason for commercial roof damage is perhaps the most predictable. When it’s maintained adequately, a commercial flat roof can be practically indestructible. This is especially true when a commercial business schedules regular seasonal inspections and maintenance.
However, one of the most common causes of commercial flat roof damage is lack of maintenance. This is especially common with gravel roofs where the roofing materials are often displaced due to the elements and unable to protect the roofing material below.
2. Impact Damage
Strong winds and summer storms can hit hard in Minnesota. The impact of falling trees and debris can take a toll on a commercial flat roof over time. Using our infrared inspection, we can identify areas of concern where water or air infiltration might occur due to previous impacts.
3. Weak Spots Around the Chimney and Exhaust
The pipes and vents on a commercial flat roof serve an important function in maintaining a building’s exhaust and plumbing. However, they also represent weak spots in a roof. For commercial flat roofs that use tar sealant rather than a membrane, they need to be checked each year.
4. Natural Aging
When flat roofs have a protective membrane such as TPO covering them, they’re practically indestructible. However, flat gravel roofs are subject to the natural aging process. If your roof has an aging tar and gravel roof, it might be time to upgrade to a durable membrane option.
