9 Signs Your Roof Needs Kornerstone!

Preserving the integrity of your commercial roof is crucial for the long-term performance of your business facility. A well-maintained roof not only protects 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 common commercial roofing issues that property owners and facility managers in Ballston Spa should keep an eye on. Identifying and addressing these concerns can help prevent costly damage and maintain your roof’s structural integrity.

1) Leaky Roof

Roof leaks are a frequent challenge for owners of commercial properties. They can lead to water damage, mold growth, and costly repairs. Typically, these leaks result from damaged or deteriorating roofing materials, such as 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) Pooling Water

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

3) Roofing Material Wear & Tear

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

5) 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 your 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.

6) 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.

7) Poor Installation

Improper installation of roofing materials or subpar workmanship can result in various roof problems over time. 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.

8) Clogged Drains and Gutters

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

9) Vents and HVAC

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

Frequently Asked Questions

Do I need a roof repair or full replacement?

If your shingle roof is under 15 years old and the damage is in an isolated area, you likely only need a repair. However, if the damage covers a significant portion of your roof or your roof is nearing the end of its life, then it could be time for a roof replacement.
