No one’s eager to do it. But sometimes roof replacement is necessary. But how can you tell if it’ss time for roof replacement?
There are some signs you can look for to determine whether roof replacement is in order.
Age of the roof
Asphalt shingle roofs last 20 to 25 years or more. But all things come to an end and asphalt shingles are no exception.
The length of time can depend upon how many layers of shingles are in place, as well as proper ventilation, among other factors. “If you’ve lived there for many years and don’t know when the roof was last replaced, consider having a roof inspection,” according to Angie’s List.
What to look for
Before you check out the roof itself, look in the attic for beams of light, stains and streaks that could indicate leaks.
When eyeballing the roof, check to make sure shingle lines are straight and look for sagging or other irregularities. Sagging could indicate rot. When you clean gutters, check for asphalt granules, an indication that shingles could be breaking down.
“Shingles should lie flat against the roof; if you find patches that are cracked, damaged, or buckling, then repairs are in order. While you’re at it, check the gutters and downspouts for shingle granules—a roof that is losing a lot of granules may be at the end of its useful life,” according to Bob Vila.
Also look for vegetation on the roof.
As Bob Vila points out, “Moss can look great in a shady corner of your yard but on a roof, it spells trouble. Moss (and likewise mold and fungi) indicate there may be trapped moisture, which can ruin a roof. To do away with moss that collects in shaded corners of your roof, use a stiff brush but be careful to address any underlying problems.”
