What “Wears Out” Roofs?

Exposure

Either long-term exposure to the elements (sun, water, freeze-thaw) or short-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

Forgetting About Maintenance

This is perhaps the single biggest cause of premature roof failure.

Change in the Use of the Building

e.g., an increase in the interior relative humidity of a building can cause severe condensation problems within a roofing system
