Wind speeds up to 90 km/h were clocked in that October storm, but speeds even half of that begin causing damage. The biggest problem is wind getting under the flashing or edges of a roof. From there it starts lifting the roofing material, allowing water to get into the underlying structure. If the roof is older or has not been well-maintained, wind inevitably gets under tears or deteriorated sections. Signs of wrinkling or bubbling mean the integrity of the roofing system has been compromised. It is crucial to have this fixed as soon as possible to avoid roofing failure and higher repair bills or replacements costs.
But, not all signs of damage are immediately visible. Strong wind can actually remove the gravel on built-up roof (BUR) systems. This drastically reduces the life of the roof, resulting in more frequent repairs or an entire roof replacement if the problem is ignored long enough.
We recommend having a flat commercial roof contractor out to inspect your building’s roof periodically throughout the year, and especially after severe weather events like windstorms.
