Why Roofing Maintenance?

There’s an old saying heard often in the roofing industry:

“A roof accounts for only 10% of the total cost of constructing a building, but 90% of its problems down the road.”

What “wears out” a roof?


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

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 the roofing system

What can cause immediate problems?

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

Unintended Abuse…

Vandalism or accidental damage…even a small hole can let in a large amount of water into the roofing system

Costs of NOT performing routine maintenance?

  • Costs of damage to building interiors (furnishings & fixtures)
  • Costs of damage to merchandise and inventory
  • Costs of damage to equipment (computers, electrical, HVAC, etc.)
  • Costs from lost use of space
  • Costs and exposure to issues of air quality and work environment
  • Costs of legal claims (“slip & fall” accidents)
  • Costs of water damage clean-up
  • Costs of energy loss through wet and damp roof insulation in both the heating and cooling seasons
  • Costs of business interruption
  • Costs associated with higher insurance premiums due to more frequent claims arising from water damage
  • Costs of premature roof replacement
