Common Types of Commercial Roof Repairs

Commercial roofs are built to be durable and withstand a variety of weather conditions, but over time, even the most resilient roofing systems will require repairs. Regular maintenance and timely repairs are essential to extend the life of a commercial roofing and prevent costly issues down the line. Here are some of the most common types of commercial roof repairs that business owners may encounter.

1. Leak Repairs

One of the most common and potentially damaging problems for commercial roofs is leaks. Water infiltration can occur for various reasons, such as punctures, damaged flashing, or deteriorating seals. If left unattended, leaks can lead to mold growth, water damage, and compromised structural integrity. Identifying and repairing leaks early is crucial to maintaining the health of your roof. Regular inspections can help spot leaks before they cause major problems.

2. Ponding Water

Flat and low-slope commercial roofs often experience ponding water, which occurs when water pools on the roof after heavy rain or snow. While commercial roofs are designed to drain water efficiently, debris buildup or poor drainage systems can lead to water retention. Over time, ponding water can weaken the roofing material, causing leaks, sagging, or even roof collapse. Addressing drainage issues and ensuring the roof is properly sloped can help prevent this issue.

3. Blistering and Bubbling

Blistering and bubbling can occur on commercial roofs when moisture or air gets trapped between layers of roofing material. This is particularly common with membranes such as EPDM, TPO, or modified bitumen. Blisters may appear as raised areas on the surface of the roof and can eventually lead to cracks or leaks. Repairing blisters involves removing the affected area and reapplying a new section of the roofing membrane.

4. Damaged Flashing

Flashing is the material that seals edges, corners, and roof penetrations like chimneys, skylights, and vents. Over time, flashing can deteriorate due to weather exposure, causing it to crack, lift, or pull away from the roof. Damaged flashing can allow water to seep into the building, leading to leaks and other structural issues. Repairing or replacing damaged flashing is a common and necessary part of commercial roof maintenance.

5. Roof Punctures

Foot traffic, falling debris, or weather events such as hailstorms can cause punctures or tears in the roofing membrane. While small punctures may not seem like a major issue, they can allow moisture to enter the roof system, leading to larger problems. Punctures should be repaired promptly to prevent further damage.

Regular maintenance and timely repairs are essential for preserving the longevity of your commercial roof. Addressing issues like leaks, ponding water, and damaged flashing early can help avoid more extensive damage and costly repairs in the future.
