It is important to consider the following factors when determining if you need to replace your roof or only a roof repair:
- The age and condition of your shingles
- The local climate
- Your budget
- Your plans for the house
The Lifespan of Your Shingles
The laminated, self-sealing asphalt shingles have a lifespan of 25 plus years, with warranties varying from 30 to 50 years. The traditional 3-tab shingles last between 15 to 25 years, with warranties ranging from 20 to 30 years. Thus, if your last roof replacement happened more than two decades ago, there is a good chance that you may need to replace it once again.
Signs of Weathering and Damage to Your Shingles
Weathering leaves visible shingle damage such as curling, clawing, cracking, splitting, algae growth, and blistering. Sun exposure, high winds, hail, and humidity all contribute to weathering, causing the shingles to age prematurely. The most common problem is overexposure to harsh ultraviolet rays. Since prairies cities like Calgary and Edmonton receive over 2,300 hours of sunlight annually, this can cause significant damage to asphalt shingles.
On old roofs, the sides facing the sun typically have more notable damage than the shaded sides. This damage can manifest as many cracked and curled shingles, while more severe cases can reveal rot, shrinkage, and the loss of the protective outer shingle coating. If such a state is observed, a roof replacement is required.
Roof leaks can be caused by:
- Missing or damaged shingles
- Improper installation (Including improper installation of flashings and vents)
- Pooling water
- Lack of roof maintenance
- Ice damming
Roof leaks do not necessarily mean a roof replacement; An inspection shall be done to gauge the extent of the damage.
