There's a leak in your roof. Or maybe it just looks worn. Whatever the reason, you're starting to wonder if it's time for a replacement. The decision to replace your roof isn't always easy. If there are obvious issues, such as a gaping hole in the middle, you clearly know a replacement is in order - pronto. But other signs that you need a new roof may seem subtle.

No one expects you to understand the complexities of your roofing system - leave that to the pros. But knowing when to call in the roofing experts can save you time, money and aggravation. If you suspect that your roof is nearing its end, take a look at some of the signs that you need to replace it.

While seeing one sign may not be enough to replace your roof, it is an indication that you need to call a roofing professional and have them evaluate what's going on.

Strange Shingles

Those formerly flat asphalt shingles suddenly look curved. When your shingles start curving upwards or buckling, it may be time to replace the entire roof. Keep in mind, one or two odd-looking shingles typically isn't a symptom of a larger problem. A bird may have pecked its way across a shingle or a squirrel could have pulled an end up. But when the problem is clearly visible across most of your roof, a pro needs to take a look.

Your roofing contractor can assess the shingles and help you decide based on the facts. It's possible there's only some slight damage, and that the roofer can replace an area or just a few shingles. In some cases, strange shingles are a result of damage (again, from animals or from the weather). This type of problem doesn't require an entirely new roof.

Missing Shingles

There are bare spots on your roof where shingles used to be. Like curving, missing shingles may indicate that it's time for a full replacement. It may also mean that there is a spot of storm damage. In either case, you need to replace the missing shingles at the bare minimum. Missing shingles allow water to get in, which can damage your attic, walls or anything underneath the roof.

Water Leaks

You don't see missing shingle or any holes in your roof. But water is still coming in every time it rains. This could indicate a number of different issues. Sometimes small cracks, breaks and holes are enough to cause major water damage inside. That said, you'll also find plenty of other reasons that explain what seems like a leaky roof.

Condensation from an unvented attic can cause wet spots inside. The same goes for flashing that has passed its prime. When the flashing around your chimney or other places on your roof breaks, wears out or leaves gaps, water can get in.

Sometimes a leak from above doesn't even indicate a real problem. In other words, something might not have broken. An open attic window or an uncapped chimney can let water in too.


If you have leaks, curled shingles or some other issue, and your roof is decades old, it's probably time for a replacement. The average residential roof can last for roughly 20 years. That doesn't mean that every roof will last this long or that some can't last longer. Your roof's ability to stand the test of time depends on what it is made from, the climate, the weather and other factors, such as tree branches that regularly hang onto the shingles.
