It’s always a good idea to evaluate your roof periodically to make sure everything is in top shape. Roofs are incredibly important to your home’s structure, and you want to make sure yours is up to the task of protecting you and your family. Here’s what you need to know about when to examine your roof.

First, know how old your roof is. If you didn’t install it and you’re not sure, check the inspection report from when you purchased your home. You can also ask a roofing company or building inspector to look at the roof and estimate its age and condition. Generally, most roofs last between 20 and 25 years, so if yours is older than that, it’s a good idea to get it looked at and possibly replaced.

You should spot-check your roof twice a year, once in spring, once in fall. If safe, use a ladder to access it and look for trouble spots, but also check your attic for damage. You’ll want to be on the lookout for signs of water damage, like wet spots, mold, and discoloration. Look for broken or missing shingles, and check for any gaps between the roof and chimney or other areas. Not feeling up to it? Reaching out to a professional roofing contractor for help inspecting is always the best option.

It’s also a good idea to watch the homes around you — they experience the same weather yours does and were likely built around the same time. If your neighbors are getting new roofs, do a roof inspection to see if your home needs one too.

Finally, after a significant weather event, like heavy winds or a hail storm, check for exterior damage as soon as it’s safe. Look for broken or missing shingles, debris, or any other signs of damage. If you find any, contact your insurance company to report it, and then reach out to a professional roofer for help.

Taking the time to periodically examine your roof will help keep your home safe and keep repair costs down. Don’t forget to check it twice a year, and if you ever notice any damage, get it fixed right away.
