Your typical asphalt shingled roof has a lifespan of close to 25 years before it should need any repairs or replacements, barring no damage, of course. If you do not know the initial installation date of your home’s roof, there are a few signs to look for in determining how old a roof may be and if you may need a new one.
Over time, those granules that make up the surface of your roof start to come off. Things like rain showers over the years, or melting snow if you get that in your area, are weather issues that can beat up your roof. If you have a two-story home, your gutter placements are a great place to look. In the areas where your gutters direct water runoff, how do the shingles look? If they are a little dark and smooth, chances are the granules have started to wash off. During your routine roof care, check inside your gutters while you are up on the ladder. If you see little tiny stones in the bottom of your gutter, those are the granules washing off your asphalt shingles, and it is probably a sign that your roof has hit old age.
Flashing is the stuff you see around any opening on your roof. Think around the chimney, skylights, vents, etc. As flashing ages, it can start to rust, causing holes when left untreated. It can also bend, warp, or crack, leaving your roof exposed to leaks. With routine roof care, most flashing is now meant to last quite a long time, so if you see this starting to happen on your home, it may be time for a new roof.
When looking at a new roof, one thing you will notice (if installed correctly) is a nice, flat roofline. The shingles are straight, lying flat, and ready to guard your home. If you’re trying to determine the age of your roof, look for curling or buckling shingles. Over time, with exposure to heat and the elements, shingles start to shrink and warp. It can also be a sign that you may have leaking underneath your shingles. Routine roof care is definitely a top priority to making sure your shingles last their full lifespan.
A definite sign of an old roof can actually be determined by the inside of the home. Head into your attic or crawl space during the day and keep the lights out. If you see daylight through slats in the roof, it is most definitely a sign that your home has just about had it, and it’s time for a new roof. The only daylight you should ever see is a little around the eaves of the roof. While you’re up there, you should also look for signs of moisture. A well-cared-for roof should not allow any water into your home.
With a proper roof care regimen and checklist, you might not be able to determine an exact birthdate for your roof, but you can at least determine if it has any years left.
