Depending on what kind of commercial roof you have, it can last ten to forty years before it needs replacement. However, if you’ve taken ownership of the property midway through its life span, you might not know how many years are left before it needs to be updated. The guide below looks at common signs it is time to call a roofing contractor for a new installation.

How to Know You Need New Commercial Roofing

1. Water Problems

While small roofing leaks can be repaired, often these issues are not spotted until they grow large enough to damage attic insulation, walls, and ceilings. Mold might also start to develop due to moisture intrusion.

Large or widespread water damage often requires a roofing replacement since the wooden support structures, known as the decking, are also likely damaged. Leaving it as is could result in sagging or potential collapse.

2. Exterior Blistering

Water damage can lead to blistering on the exterior of the roof. When water from a leak gets trapped in insulation inside your building, the resin in the roofing materials begins to deteriorate, which releases trapped water vapor and gas bubbles. Those gases then cause the outer shell to expand. This expansion leads to a blister that will eventually crack.

3. Membrane Issues

Many commercial buildings have a flat roofing membrane made from synthetic rubber, thermoplastic, or bitumen. If this material has bald spots where the membrane is missing, worn away, or lifted or if there are open laps where the adhesive is failing, your seal is compromised and your facility is at risk for water damage. Always check your membrane after a major storm.

4. Shingle Damage

Some commercial roofs have shingles, and just like with residential systems, once shingles begin to curl, split, or go missing, call your roofing contractor. While a damaged shingle or two is easy to replace, it is more cost-effective to install a new roof when large sections are affected.
