As a homeowner, you need to be aware of signs that you need a new roof, and not wait until you notice a leak in your bedroom ceiling. Regular inspections will help you stay on top of your roof's condition.
To know when you need to repair or replace your roof, look for these signs:
1. Roof age
Do you have an asphalt shingle roof? If so, experts agree that your roof has a 20-25 year lifespan. It is helpful to know if you only have one layer of shingles, if the roof has been replaced before, and if your roof has proper ventilation. If your current roof was installed over another layer or layers of roof, and if it is more than 20 years old, you need a new roof.
2. Shingles curling, buckling, or missing
If you stand back and look at your roof slopes in direct sunlight, and see shingles curling, buckling, or have blown away in a Calgary chinook, or you are finding roof granules on your sidewalk, your shingles aredue for replacement. Or you may need a new roof.
3. Roof valleys
Roof valleys are also an important sign of your roof's health. If you notice that there are shingles in this area which are falling apart or missing, you definitely need a new roof. Because rain and snow flow through the valleys into your gutters, any places that are damaged could lead to roof leaks.
5. Chimney flashing
Chimney flashing is extremely important to the integrity of your chimney and the rest of your roof. Most flashing consists of roof cement or tar, and these wear out over time and need to be replaced. You should consider replacing the flashing with a durable, water-tight, metal flashing system.
6. Shingle granules in the gutters
A roof problem can become a gutter problem. Check your gutters for piles of shingle granules. Roof shingles shed more granules when they are aging out. You might also see dark spots on your roof which might indicate that patches of granules have worn away, and it is time to replace your roof.
7. Take a walk on your roof
You can't really tell what is going on with your roof without taking a walk on it. If any part of your roof feels spongy or bouncy as you walk, chances are underlying water damage has weakened the decking. You should also go into your attic to look for daylight, and to check your insulation for moisture.
