If you’re the kind of person who notices details and pays attention to small things, then you’ll probably see when it’s time for a new roof. Plenty of smaller signs can indicate when your roof needs replacing before it fails completely. However, if you don’t pay attention to detail as much as you think, there are some bigger indicators that it might be time to replace your roof.

Rot and Mold

These are two signs that indicate a decaying or rotting roof. If you see mold or rot on the eaves of your house, it could be a sign that the shingles are rotting from the inside out. The same goes for other areas of your roof that are exposed to water, like the valleys or parapets. Rotting shingles can be a real fire hazard, so watching for signs of decay is important. Mold can also become hard to get rid of if you let it spread. You can also check for missing shingle tabs. If you see that some of your tabs are missing, you may have an issue with rot under your shingles. If you do notice these issues, reach out to local professionals like Ketchum Roofing & Windows. Experts can inspect the situation and give suggestions on whether it needs repair or replacement.

Sagging Timbers

The roof framing supports the roof and keeps your house safe from rain and snow. If you notice that the roof timbers are sagging, it may be a sign that they can’t support the weight of your roof anymore. A sagging roof might also signify structural issues, such as termite damage. It’s best to have your roof inspected by a professional if you notice any sagging. 

Loose Joints and Corrugated Sheeting

Loose joints are a sign of shoddy or improper installation. If your roof’s joints are loose, it might be time to replace your roof. Corrugated sheeting, the material used on most metal roofs, is generally very sturdy, so it doesn’t break down as easily as shingles. However, if you notice that the corrugated sheeting is loose, it may be a sign that the nails or screws holding the sheeting are rusty, which could lead to leaks.


It’s important to watch for signs of wear and tear on your roof, especially if you live in an area where you get a lot of snow or rain. If you see that your shingles are worn or broken, or if you notice any other signs that your roof may need to be replaced, it’s a good idea to have it inspected by a professional. When your roof is inspected, the inspector will let you know what repairs are needed, if you need a new roof, and how much the whole thing will cost.
