Exposure
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 – i.e., if a small problem is not repaired, then a large amount of insulation can be damaged

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 the roofing system
