For most roofing contractors, any sign of rot is an indication of a compromised commercial roof. In addition to being unsightly, this problem can put the health of everyone in the property at risk. Rot breaks down roofing materials, exposing the roof decking to the elements. If not detected and addressed right away, it can grow rapidly, leading to leaks and other issues.
What Causes Flat Roof Rot?
Too much moisture is the primary cause of rot in flat roofing systems. It can have several causes, but this is usually a result of the attic’s lack of ventilation, which then leads to high humidity. When this happens, the roof’s wooden components begin to feel damp to the touch. Moisture levels of up to 20% are enough for rot to spread to the rest of the roof parts, sending microscopic strands of the wood-eating fungus into surrounding fibers.
Ponding problems can also result from an inadequate or compromised slope, as well as poor drainage due to clogs or defective gutter systems. Signs of roof membrane damage allow water to penetrate, increasing the likelihood of rot.
What Are the Signs to Look For?
In addition to water stains and streaks on the ceiling and interior walls, one sign that a commercial flat roof has rot is sagging. This could mean that the roof is starting to or has already set in. The slightest strain can put it at risk of collapsing, so it’s best to call a roof repair professional to inspect and perform the necessary fixes.
Cracked seals are another indicator of rot. This problem can be found around chimneys, vent pipes and other structures standing on the roof surface. A discolored fascia is also a tell-tale sign and must be addressed right away.
How to Prevent Flat Roof Rot
Following certain preventive measures can help you avoid serious roof rot damage. These include:
-
Ensuring the attic temperature is regulated with proper insulation and ventilation
-
Scheduling professional inspections at least twice a year.
-
Cleaning the roof periodically so the drainage can work as intended.
