Knowing when the last time your roof was replaced and knowing the warning signs of a failing roof is extremely important.
1. Curled or buckled shingles
Shingles can curl in two ways: cupping and clawing. When your shingles cup, the edge of the shingle turn upward and when your shingles claw, the edges stay flat and the middle starts to come up. Both types of curling are signs of weathering and indicate a problem, including leaks, are going to be in the near future.
When your shingles buckle, it's because of moisture in the attic space of a home forcing nails to push up and out of the roof's decking.
2. Missing shingles
Missing shingles are an open pathway for water to enter your home. Most people will opt to have these spots patched but over time, as the issue persists, your roof will begin to look like a checker board. At this point, many homeowners decide to replace the entire roof.
3. Attic temperature is differs from the outdoor temperature
The outdoor temperature and the temperature in an attic should be consistent from your ventilation system circulating the air in and out of your attic. This ventilation is necessary to prevent ice dams along your roof. Other signs would be the paint on your exterior of your home blistering and peeling as a result of poor ventilation.
4. Leaky chimneys
When your roof and chimney are installed, they should be flashed properly to stop any outdoor elements from coming inside of your home. If you notice water leaking in through your chimney it's because it was not flashed properly
5. Moisture and mold
When an attic isn't ventilated properly, the warm, moist air rises and gets trapped. This causes condensation to develop on the underside of the roof and eventually, the nails will get rusty and mold will grow. Overtime, the plywood will rot out and your roof will need to be replaced.
This can happen in new homes and old homes, depending on both the ventilation and from over-insulating - which can cause the vents to be blocked.
6. Missing granules
If you've recently had your roof repaired and you're finding excess granules in your gutters, there's no need to worry, those are just the loose, extra ones.
If your roof is 10-15 years old and you're finding a build up of granules in your gutters, it's a sign your halfway through the lifespan of your roof. Granules help keep the sun off your shingles and without the proper protection, they deteriorate quickly.
7. The entire roof is sagging
When your roof is sagging, it's typically an indication of a structural issue that needs attention. When you notice your roof is sagging, it's important to call a professional as soon as possible to address the next steps.
