When your commercial flat roof functions properly, it's easy to think it needs no maintenance or tune-up. However, you should plan for commercial roof inspections on a regular basis to avoid the consequences of developing problems. A-Plus Roofing Co. can help you when these five signs calling for flat roof maintenance present themselves.

 

1.      Frequent Leaks
When one leak leads to another, it's time to call A-Plus Roofing Co. Once leaks start, they indicate that the roof system has reached an age where components need some shoring up. Often, leaks can be prevented before they start. Using advanced infrared technology, A-Plus Roofing Co. can find where moisture has penetrated under the cap sheet or bitumen (tar) build-up, waiting for an opportunity to pour into your facility.

2.      Separating Membrane Seams
If your building enjoys the protection of a membrane system, the seams could develop weak spots and "fish mouths." A fish mouth break in a seam presents an obvious problem. While there may still be some adherence to the membrane sheet overlaps, it will likely open completely in the near future. One loosened seal reveals the need to probe the rest. A-Plus Roofing Co. employs installation and repair experts skilled to trouble-shoot every type of membrane roofing system.

3.      Cracking Tar
As tar and gravel roofs age, the tar shrinks which, in time, produces cracks. As it pulls away from walls, protrusions, expansion joints, and even from itself, the Minnesota freeze-thaw cycle begins to widen separations until leaks break through. A-Plus Roofing Co. can seal over those cracks with a modified bitumen membrane to forestall the need for a roof replacement for another few years.

4.      Loose Flashing Metal
Protrusions, HVAC curbs, and parapet walls — anywhere metal flashing contributes to a watertight seal at the edges — need regular check-ups. As the fasteners, either nails or screws, begin to work their way out of the substrate, the flashings become vulnerable to wind and water penetration. A thorough inspection by A-Plus Roofing Co. will find loose metal flashings, and our knowledgeable, professional crew will re-secure them before they become more costly repairs. Also, our crew will hunt for shrinking liquid-applied seals and replace them where needed.
