Would you know the signs of a compromised commercial roof just by looking? Sometimes commercial roof issues show long before serious leaks start, but it often takes a trained eye to see what’s going wrong – especially if you rarely venture out onto a commercial roof to take a look yourself. So, what are some of the things we look for when carrying out a commercial roof inspection? Here are the key signs that something is going wrong.
Standing Water
Many commercial rooftops are low-slope, which means they are designed to look flat and carefully channel water off into drainage systems. However, when drainage systems get blocked by debris or something else goes wrong, water ends up lingering on the roof, sometimes for days after it rains. This is very bad for roofing materials and a sign that immediate action needs to be taken.
Discoloration
Discoloration on roof panels or strips is a sign that materials need a closer look. This can mean that panels are suffering weather damage and may be compromised, or that a leak may have gotten underneath a roof membrane. If that spot is letting in water, it needs to be quickly patched by an experienced roofer before the damage spreads.
Damaged Flashing
Flashing refers to the metal strips around roof edges and objects like vents or chimneys. Flashing isn’t as common on commercial roofs, but it does exist: If it starts rusting or warping, or the fasteners come loose, then that flashing can let leaks in underneath the roof. A good roof inspection always makes sure that any flashing is still properly secured and isn’t suffering any damage.
Vegetation
Moss and algae can form on rooftops, especially with the right climate or shade. This can damage your roof and cause severe problems over time. Vegetation issues are a sign that your roof needs special coatings or materials to prevent this from becoming an issue.
Cracks or Blisters
Cracks and blisters are signs that a roof membrane is reaching the end of its life or showing severe weather damage, and may be compromised by a leak. In this case, the cracked area needs to be removed and patched with a similar material to keep the roof secure.
Punctures
Commercial roof membranes can also be punctured. This tends to happen during a windstorm when heavier debris hits the roof, or can be caused by people walking on the roof when they shouldn’t be. Punctures are a direct route for water to leak into the roof and should be addressed immediately – but sometimes they can be hard to see at a glance. Patching the area usually takes care of the problem.
Interior Water Stains or Rust
A good roof inspection always includes an interior scan to look for any potential water stains or rust problems that could indicate the presence of a leak. A roofing professional will be able to pinpoint the source of the leak if any damage is apparent.
