Common Commercial Roof Issues We Fix
Roofs don’t fail overnight, but when they do, the damage can escalate fast. Our commercial building roof repair job is to catch those problems early or act fast when the damage is already done. We specialize in identifying and resolving the most common commercial roofing repair problems, including:
- Roof Leaks – The most common complaint in commercial buildings. From worn flashings, punctures to cracked seams, we work on the source and seal it on a prior basis.
- Membrane Damage – The durability of TPO, PVC, and EPDM membranes can be affected by factors such as UV exposure, ponding water, and foot traffic, leading to premature deterioration.
- Flashing Failures – Poorly installed or aged flashing allows water to sneak in around roof edges, vents, or HVAC units. We repair or replace flashings with precision.
- Ponding Water – Standing water on flat roofs is a red flag. Improper drainage systems can cause structural issues and membrane rot. Our commercial roof leak repair addresses both the symptom and the cause.
- Blistering & Cracks –These are signs of trapped moisture or thermal stress. If left unchecked, they will shorten the lifespan of your roof significantly.
- Seam Separation –When seams split or lift, water gets in. Our commercial roofing repair team seals or patches vulnerable areas with long-term durability in mind.
- Metal Roof Corrosion – For commercial metal roof repair, we address rust, worn fasteners, and surface damage to restore weather-tightness.
