A GAF Certified Maintenance Professional (CMP) is your very best choice for your commercial roofing maintenance program

A commercial roof is a huge investment for a building owner, so dont install a new one and forget about it. If you want something to perform well, you have to maintain it. If you don't, you're putting your property at risk of damage from leaks, not to mention the risk of your guarantee coverage being jeopardized.

Either long-term exposure to the elements (sun, water, freeze-thaw) or shorter-term exposure to damaging air pollutants and chemicals

Structural Movement

Such as building settlement or expansion/contraction not accommodated by the roofing system

Biological Growth

Such as vegetation in areas of standing water or algae

Not Fixing Problems Promptly

These can add up to a much shorter roof life e.g., if a small problem is not repaired, then a large amount of insulation can be damaged


Extreme Weather

Lightning, high winds, hail, drenching rains that overflow the flashing heights

Equipment Additions

Improperly added equipment or other items improperly added on the roof (items added by tenants are a very common source of roofing problems)

Trade Damage

Punctures, holes, etc. caused by trades other than your roofing contractor
