How Old Should a Roof Be Before Replacing?

You might be asking yourself how old a roof should be before replacing it. The answer can be complicated, as different roofs last different lifetimes. If you have a slate roof, that can last hundreds of years. If you have a metal one, that can last your whole life. But most homes don’t have those kinds of roofs, most are made up of asphalt shingles.

The average life expectancy of asphalt shingle roofs varies between weather and states. Most of the time it’s between 10 to 30 years. That’s usually an average of 20 years. Once it starts creeping up above 30 years, even considering good condition, it might be a good idea to replace your roof. Fortunately for you, there are plenty of signs to look out for in an aging roof.

Water Damage – a Huge Sign

Water damage is probably the first thing to look out for in a roof that’s getting too old. If you’ve been wondering how to stop a roof leak in the rain, then your roof is probably too old and needs repairs. Keep an eye out for any discolored stains that are brown, gray, or yellow. Moisture marks and peeling paint could also indicate water damage. Though it’s on you to fix your roof if you find a roof leak in the rain, it might be best to consider that it’s above your pay grade and pass it off to professionals to fix. Roofing can seem deceptively easy, but it can also be tricky.

Other Signs Your Roof is Too Old

Water damage, while a huge and important sign, is not the only sign your roof is too old and needs replacement. Another keen sign is if your roof sags. If it does, it may be another sign of a type of water damage – moisture stuck and rotting away at the roof. Curling shingles are another sign that the damage is already done, your roof is getting old, and that you need to get a replacement. Because of the way shingles are made, they should not be curling up once set down and emblazoned by the sun, especially after years. Besides missing shingles being another clear and huge sign, you should also look out for moss, mold, or fungi. They can be the cause of the same problem – trapped moisture, which then ruins the roof even more.
