A roof is the most important element of the home—if it has leaks or old, mildewing material, it’s going to eventually make the entire structure vulnerable to extensive damage. Therefore, it’s imperative to inspect the roof and surrounding materials, such as flashing and attic space, on a regular basis. This way, you can detect when simple repairs are required as the years go by, or when you have to budget for a major roof replacement.

First, you need to differentiate a re-roof versus a roof replacement. Basically, a re-roof entails layering new shingles (or other roofing material) over old existing ones that are still in good shape. Minor repairs should be done beforehand. A re-roof lays overtop the old one and should only be performed once. 

A roof replacement entails removal of all existing roof covering. Then repairs can be made to the substrate. A new roof installation completely addresses all the roof issues, including leaks.

Although you may save money with a re-roof, and it may be suitable only when there are minor roofing issues. But if the roof is ready to give out, replacement is the only option.

Additionally, extreme weather can cause damage to several types of roofing material. Then, how can you be sure, barring a roof inspection, if you need a re-roof or an entire roof replacement? There are a few methods of detecting the answer.

YOU MAY REQUIRE A ROOF REPLACEMENT IF:

• The existing roof looks in poor condition, with numerous shingles missing. Furthermore, if the roofing material has become uneven and significantly damaged, laying a re-roof flat on top would be impractical.
• You don’t know the age of the current roof and it may be past its lifespan.
• The roof has been re-roofed before and has too many layers of shingles. 
• After checking local building codes, you discover a re-roof is the only viable option.
• You discover warped or rotting wood and too much damage that requires replacement.
• The roof structure reveals signs of sagging or leaks.
• You desire newer, lower-maintenance roofing material.

Alternately, if the existing shingles lay flat and the decking is in good condition, then a re-roof will suffice, and also save money. When you have the option of leaving the old layer underneath, it negates old shingle removal, disposal, and recycle fees.
