Commercial Roof Leak Repair Guide
After a heavy rain or snow storm, the last thing on your mind as a commercial building owner is whether or not your roof is leaking. But one visible drip, puddle, or streak is enough to strike fear as they all are signs that water has infiltrated your commercial roof.
When you notice a leak, what should you do? Our guide provides you with everything you need to know about your commercial roof leak, from identifying its source to what you can expect from a professional roofing contractor when they visit.
No matter how small your commercial roof leak is, it’s important to take care of it sooner than later to avoid potentially expensive and dangerous consequences.
How Will I Know if My Commercial Roof Has a Leak?
Identifying a leak in your commercial roof isn’t always as easy as seeing a puddle in the middle of your floor. Depending on the type of leak you have, there are various signs to look for that will help you know whether or not your roof is leaking.
Indoor Signs of a Commercial Roof Leak
From water stains to puddles, you’re far more likely to notice a roof leak inside your commercial building than outside. After rain and snow storms, it’s best practice to look around your building for any signs of a leak, as even the slightest drip can lead to severe issues.
Water Stains and Discoloration
Yellow or brown water stains on ceilings, walls, or around light fixtures indicate a commercial roof leak. These stains are hard to ignore, even though they vary in size and shape.
Dripping Water or Puddles
The most obvious sign of a commercial roof leak is dripping water or puddles on the floor. If you find any puddles, look up at your ceiling to determine where the water is coming from. You may notice signs of a more significant leak.
Dripping water and puddles are signs of a potentially dangerous problem, and you must reach out to a commercial roofing professional as soon as possible.
The growth of mold and mildew often result from accumulated moisture inside the walls of your building. If you notice a musty smell, there is the possibility that water has leaked in from your roof and is creating life-threatening mold spores.
Sagging Ceilings or Walls
Once water infiltration leads to structural damage, you and your commercial roof are in danger. Too much water leakage causes ceilings or walls to sag or bow, and you must reach out to a commercial roofing professional immediately.
Outdoor Signs of a Commercial Roof Leak
When checking your commercial roof for leakage outdoors, look at the materials themselves. Missing shingles, torn roof membranes, and clogged gutters lead to potentially expensive repairs.
Damaged or Missing Roofing Materials
Cracked, blistered, or missing shingles, tiles, or roofing membranes expose your commercial roof to leaks. Call a commercial roofing professional for repairs and maintenance at the first sign of any visible damage.
Clogged or Damaged Gutters and Downspouts
Pools of water on your roof weaken the structure of your commercial roof, which is why unclogged gutters and downspouts are so important. Without a way for the water to move off the roof, the water overflows, leading to leaks and damage along the building’s exterior walls.
Water Pooling on the Roof
Always check the roof for any signs of water pooling after a rainstorm. The longer water stays on the roof, the integrity of the materials will weaken, leading to possible leaks.
Identifying the Source of a Commercial Roof Leak
Ridgeworth Roofing utilizes various proven methods from our decades of experience working with commercial roofs to help identify and fix leak-related issues. Our trained experts have helped thousands of commercial building owners in the Chicagoland area repair their roofs.
A comprehensive roof inspection allows roofers to carefully inspect your entire roofing system, including the membrane, flashings, seams, gutters, downspouts, vents, skylights, and other roof penetrations. We recommend only allowing trained commercial roofing experts as it’s easy to slip, fall, or injure yourself performing a self-inspection.
Like how mechanics identify leaks in tires, roofers will simulate rainfall by spraying water over specific roof areas. They’re looking for signs of leakage inside the building while narrowing down the potential areas of concern.
Moisture Detection Technology
For trickier leaks, commercial roofers use moisture detection technology, such as infrared thermography or moisture meters, to identify areas of trapped moisture or hidden leaks beneath the roof surface. These tools allow them to detect temperature variations or moisture levels that indicate the presence of leaks.
Tracing Stains and Water Pathways
The simplest way to identify the source of a leak is to trace the paths of water stains or water penetration from the interior back to the roof’s exterior. This involves analyzing the pattern of water stains on interior surfaces and determining how water might have traveled from the roof’s entry point.
What Options are There for Fixing My Commercial Roof?
Before immediately suggesting a complete commercial roof replacement, other repair methods are cost-effective and extend the lifespan of your building’s roof.
Patching and Sealants
When it comes to minor leaks, we often use patching and sealants. First, we determine where the water is coming from; then, our team applies sealants or patches to prevent further water intrusion. This method works best for small punctures, cracks, or gaps in the roofing material.
Many commercial roofs have a membrane, such as TPO, PVC, or EPDM, which serves as a waterproof barrier. Membrane damage due to tears, punctures, or seams coming apart can sometimes be fixed by roofers applying patches or adhesives to secure the damaged sections.
Flashing is the material used to seal and protect vulnerable areas, such as vents, skylights, and chimneys. If flashing is damaged, improperly installed, or deteriorated, replace them as soon as possible to avoid serious short-term damage.
Do I Need a Commercial Roof Replacement?
Depending on the size of the leak, you may need a complete commercial roof replacement.
Roof replacement offers a comprehensive solution that addresses serious leakage issues that roofers cannot fix through repairs and maintenance. A benefit is that a roof replacement allows you to have more modern, advanced materials that extend the lifespan of your roof, improve insulation, and lower energy costs.
The only definite way to know if you need a commercial roof replacement is a consultation with a roofing contractor, as they can provide you with the safest and most cost-effective options for fixing your leaky roof.
