Here in Louisiana, the summer sun is not just uncomfortable for the people working in your building. It is actively breaking down your commercial roof.
Flat roof surfaces can reach 150 degrees or higher under direct summer sun. That heat, combined with Louisiana's UV intensity and humidity, accelerates the deterioration of roofing membranes, seams, and pe*******on seals faster than most climates in the country.
The tricky part is that the damage builds slowly and stays hidden. By the time you notice a ceiling stain or a leak, the damage inside the roof assembly is usually far more extensive than the entry point suggests.
We put together a guide breaking down exactly how heat and UV damage flat commercial roofs in Louisiana and what building owners and property managers can do to get ahead of it.
The photo is from a real commercial roof we inspected recently in Shreveport. That surface weathering is a textbook example of what years of Louisiana sun does to an aging roof membrane.
Louisiana's heat and UV exposure accelerates flat roof deterioration faster than most climates. Learn exactly what's happening to your commercial roof and how to prevent it.
