We talk about “having a roof over our heads”. But what happens when the roof over our heads is no good as a roof anymore? How do we know the signs that your roof needs replacement?
Usually, homeowners decide to change their roof once they find a leak… but by that time the damage can be extensive, and sometimes a roof needs to be replaced even though it’s not leaking.
Signs that your roof needs replacement.
1. Shingles are missing
Once shingles start peeling and falling off your roof, it’s time to get it replaced. Damaged shingles usually come off after strong winds or a storm, so make sure to have a look whenever that happens.
2. Your roof is 20-25 years old
No matter its current condition, the useful lifetime of a roof is about 20 to 25 years old. By then, you will start to see problems, such as the ones mentioned in this post. Other things that influence the lifetime of a roof include ventilation and if the current roof was installed from scratch or over the old shingles.
3. You catch shingle granules in the gutter
Some granule falloff is typical, especially after hard rains, but when you start finding more and more granules in your gutter, it’s a sign to have an expert look at your roof. It might be time to replace it.
Worn shingles with eroded granules usually appear darker than the surrounding roof.
4. Shingles are curling
Another visual sign related to shingles: once they start curling and buckling, it’s time to plan a roof change. Curling and buckling shingles may lead to water infiltrating your roof, and mold and rot attacking the structure.
5. Energy bills are increasing
When a roof is damaged, it doesn’t retain heat (or cool air, in the summer) as well as it used to. Your heater/air conditioner has to work harder to maintain the same temperature, which uses more electricity.
An increasing power bill can be a sign that the roof needs changing. While you’re at it, you should also have a look at your windows!
6. Algae is growing on your roof
No, it’s not a sign of “good old age” when green algae is growing on your roof. Algae spores are transported by the wind and take hold wherever they can. And they grow fast, damaging the surface they’re growing on.
If you see algae on your roof, it’s definitely one of the signs that your roof needs replacement. It won’t take long before the algae does worse damage and reaches the interior of your roof structure.
7. Your ceiling is leaking
One of the most obvious signs that your roof needs replacement is a failing one, but also one of the last. By the time there’s a leak in your ceiling, the damage is probably extensive and you might need to have a look at the roof structure as well.
8. There is sunlight through the roof
Once in a while, visit your attic during a sunny day and look for sunlight. If light makes it through your roof, it means that the underlayment is damaged. Daylight through the boards might look quaint, but it’s actually a sign that your roof needs to be replaced.
9. The paint is peeling
If you have painted shingles or boards, the paint peeling is one of the signs that your roof needs replacement. Although only small repairs may be required at this point, once the paint starts peeling, keep an eye out for more extensive damage.
