Question: Tell us about your experience in accounts payable. Answer: Accounts Payable is mainly concerned with effective management of creditors. Effective management of creditors calls for correct booking of invoice under right accounting heads and making timely payments so that maximum available credit limit and discount is taken.
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.
The life expectancy of such a roof is 20 years. The complexities arise when doing repair or replacement, or addressing poorly done past repairs. Homes that are 30 to 50 years old will certainly have had some roof work done. In many cases, multiple generations of tar and gravel will have been applied.
