Having regular maintenance done on your existing roof is important to ensure it lasts as long as possible. You might hear that the average lifespan of a residential or commercial property roof is between 10 and 20 years. The estimates vary greatly and will depend on several factors.

The most important factor that affects how long your roof will last is, without a doubt, how well you maintain it.

Roof maintenance includes:

  • replacing damaged metal roofs
  • touching up paint
  • keeping the roof watertight
  • repairing any damage caused by bad weather

Looking after these issues before they become more serious will help ensure that your roof remains in great condition all year round.
