Question: Tell us about your experience in accounts payable. Answer: Accounts Payable is mainly concerned with effective management of creditors.

That's somewhat optimistic, according to the Metal Roofing Alliance, which says a metal roof lasts 40 to 60 years while the average life span of an asphalt roof is 12 to 20 years.. Your shingles might defy predictions one way or the other.
Average three-tab roofs last about 17 â 20 years. Architectural asphalt shingles have additional asphalt making them more durable than three-tab. Warranties range from 20 â 50 years with an actual life expectancy of 30 â 50 years. Metal roofs are extremely durable, often lasting up to 50 years.
