8 Common Commercial Roofing Concerns

Maintaining a commercial roof is crucial for the longevity and functionality of your business facility. A well-maintained roof not only safeguards your property but also ensures the safety and comfort of your employees and customers. In this informative piece, we’ll delve into some of the most prevalent commercial roofing issues that property owners and facility managers in Lake George should be vigilant about. Identifying and addressing these concerns can prevent costly damage and preserve the structural integrity of your roof.

1) Roof Leaks

Roof leaks are a frequent and troublesome issue for commercial property owners. They can lead to water damage, mold growth, and costly repairs. Typically, they result from damaged or deteriorating roofing materials like cracked or missing shingles, damaged flashing, or worn-out seals around roof penetrations. Regular inspections and prompt repairs are essential to prevent further damage.

2) Ponding Water

Ponding water occurs when water accumulates on a flat or low-slope roof and fails to drain correctly. This issue can lead to roof deterioration, structural weakening, and even leaks. To combat ponding water, ensure your roof has proper slope and drainage systems in place to redirect water away from the surface.

3) Roofing Material Deterioration

Commercial roofs endure harsh weather conditions, including extreme heat, cold, and UV radiation. Over time, roofing materials can deteriorate, resulting in cracks, blistering, and curling. Regular inspections help identify signs of material deterioration, allowing for timely repairs or replacements to extend the roof’s lifespan.

4) Punctures and Tears

Commercial roofs are vulnerable to punctures and tears from various sources, including foot traffic, falling debris, and severe weather. These openings can compromise the roof’s integrity and lead to leaks. Implementing safety measures, such as walkway systems and routine roof inspections, can minimize the risk of punctures and tears.

5) Roofing Membrane Damage

Single-ply roofing membranes like TPO, PVC, and EPDM are popular choices for commercial roofs due to their durability and cost-effectiveness. However, these membranes can still be damaged by hail, sharp objects, or prolonged exposure to UV rays. Inspections should include an assessment of the membrane’s condition, with damaged areas promptly repaired or replaced.

6) Poor Installation

Improper installation of roofing materials or subpar workmanship can result in various roof problems down the line. It’s crucial to select a reputable roofing contractor experienced in commercial roof installation. A well-installed roof will encounter fewer issues and enjoy a longer lifespan.

7) Clogged Drains and Gutters

Clogged drains and gutters can obstruct proper water drainage, leading to ponding water and potential leaks. Regular cleaning and maintenance of these drainage systems are vital to ensure they function correctly, especially after storms or heavy rainfall.

8) Roof Penetrations

Roof penetrations, such as vents, HVAC units, and skylights, can create weak points in the roof’s structure if not adequately sealed and maintained. Regular inspections and resealing of penetrations are necessary to prevent leaks and maintain the roof’s integrity.

Do I need a roof repair or full replacement?
