Commercial Roofing in Covina, California

The flat roofs on the Covina businesses take the most abuse. The sun bakes the membrane, and the winter rain ponds on the low spots. Commercial roofing in Covina means the roof system that protects the building and the business inside.

Signs Your Covina Commercial Roof Needs Attention

• Ponding water on the flat roof — the water that sits for days after the rain
• Blisters or bubbles in the membrane — the moisture got under the surface
• Cracked or splitting seams — the sun dried out the membrane
• Leaks in the warehouse or the office — the water found the weak points
• Granule or coating loss on the surface — the UV has aged the roof

Why Covina Commercial Roofs Need Care

The heat is the main cause. The San Gabriel Valley sun bakes the flat membrane all summer, and the UV breaks down the surface. The seams that were sealed in the spring are cracked by the fall.

The winter rain is the test. The flat roofs pond the water, and the standing water finds the weak seams. The leaks show up in the warehouse and the office, and the water damage interrupts the business. The regular inspections catch the damage before the rain does.
