10 Signs You Need a New Roof

A new roof can be an overwhelming undertaking for a homeowner, so before you replace your roof, make sure you really need one. Some problems just require a repair, but other times a seemingly benign issue is actually a serious one.

Dark spots

Dark spots on your roof may be a sign of airborne algae invading and deteriorating the shingles and wood of your roof. Check in the attic, under the eaves, and on top of your roof for telltale streaks. Keep an eye on them over a period of rainy weather, and if they get worse, call a professional. This is a sign of an active leak.


Obviously, a leak in the roof can be a sign of a serious problem. A leak in and of itself is not necessarily a sign that your whole roof needs replacing, but don’t hesitate to call a professional if you notice it.


Rooftop gardening may be something you’ve always wanted to try, but moss growing in the roof itself and between the shingles can be a bad sign that the structure of the roof itself might be compromised. Try a mixture of half bleach and half water and see if that helps keep the moss down to a manageable level.

Warped shingles

Cupped shingles with the corners pointing up, or clawing shingles with the corners pointing down and the middle rising up, can often be a sign that your roof needs replacing.

Torn shingles

Wind and wear can tear or crack your shingles. Often, it’s more than one shingle that is torn, so many that just replacing the torn shingles isn’t the wisest option.

Spongy feeling underfoot

A spongy or sinking feeling underfoot when you walk on the roof is a sign of serious water damage. Call a professional immediately before more damage is done. A waterlogged roof is in serious danger of falling in.


Roof nears the end of its useful life at around 20-25 years, so if your roof is nearing that point, it’s probably time to have it replaced. Check your house’s improvement record, or check if others in your neighborhood are getting their roofs replaced. If all the houses in your neighborhood are around the same age, then it’s probably time to get yours replaced too.

Missing shingles

It can be difficult to find new shingles in the same color as the one on your roof, especially if your roof is getting up in years. You can find a few shingles close enough in color, but if you’re missing too many to replace subtly, it might be time to replace your roof anyway.


A sagging roof is a sad, old or waterlogged roof. Sagging roofs are dangerously close to falling in, and should be replaced as soon as possible.


If you can see sunlight through your roof, do not hesitate to call a professional. It’s probably time to replace or repair your old one.


A new roof can seem like a daunting expense, but it’s worth it to preserve the structural integrity of your whole home. We hope these tips above will help you decide if you can get by with a repair or if it’s time for a full replacement.
