Over time, commercial roofs endure significant wear and tear. As they age, various problems can develop that require attention. Early detection and resolution of these issues can save money on costly repairs and extend the life of your roof. Below are seven common issues with aging commercial roofs and the importance of hiring a qualified roof contractor in Corvallis, Oregon, for expert roofing services.

Leaks and Water Damage

Leaks are one of the most common issues with aging commercial roofs. Left unaddressed, they can cause severe water damage, including compromised insulation, electrical systems, and internal components. Common causes include cracked shingles, deteriorating flashing, and weakened seals around roof penetrations like vents and chimneys.

Routine inspections and timely repairs by a Corvallis roof contractor can identify and address leaks before they escalate, protecting your building from costly damage.

Ponding Water

Flat or low-slope commercial roofs are prone to ponding water due to poor drainage. Prolonged water accumulation can speed up the deterioration of roofing materials, lead to leaks, and create an environment for mold and algae growth.

Professional roofing services can improve your drainage systems, add extra drains, or adjust the roof's slope to prevent water from pooling.

Membrane Shrinkage

Single-ply roofing membranes, such as EPDM or TPO, can shrink over time due to UV exposure and temperature fluctuations. This shrinkage can cause the membrane to pull away from parapet walls, creating gaps that allow water to enter.

A Corvallis roof contractor can inspect your roof for signs of shrinkage and recommend appropriate repairs or replacements to maintain the membrane's integrity.

Blistering and Cracking

Blisters and cracks are common on aging roofs, especially those with built-up roofing (BUR) or modified bitumen systems. Blisters form when moisture or air becomes trapped between layers of roofing material, while cracks occur due to thermal expansion, foot traffic, or material degradation.

Routine maintenance can identify and repair these issues, preserving the roof's ability to keep out moisture.

Loss of Reflectivity

Many commercial roofs feature reflective coatings that reduce heat absorption and improve energy efficiency. Over time, UV exposure, weather, and pollution can degrade these coatings, decreasing their effectiveness.

Regular maintenance and reapplications of reflective coatings by a professional roofing contractor can restore your roof's performance and help manage cooling costs.

Damage from HVAC Systems

HVAC units are commonly placed on commercial roofs, but they can cause damage over time. Improper installation or maintenance of these systems can lead to punctures, membrane damage, or stress points on the roof.

Roofing Services can work with HVAC specialists to ensure that units are properly installed and maintained to minimize roof damage.

Structural Deterioration

The decking, joists, and supports of a commercial roof can deteriorate over time due to age, moisture, and weather conditions. Structural deterioration can compromise the roof's integrity and pose safety risks.

Regular inspections by a Corvallis roof contractor can identify structural problems early and recommend necessary reinforcements or repairs to keep the roof in safe working condition.

Conclusion

Aging commercial roofs face several challenges, including leaks, ponding water, membrane shrinkage, blistering, loss of reflectivity, HVAC damage, and structural deterioration. Recognizing these issues and addressing them promptly with the help of a qualified roof contractor in Corvallis, OR, can prolong the life of your roof, prevent costly repairs, and ensure your property remains protected.

Investing in professional roofing services and regular maintenance ensures your roof remains in optimal condition, safeguarding your property for years to come.
