1. Curling or Clawing Shingle
Curling or clawing shingles are a sure sign that your roof has aged and succumbed to excessive heat. Curled or clawing shingles are highly susceptible to high wind uplift and ice damage. Shingles will become rigid and break easily and lose edges.
- Missing Granules and Bare Spots
Poorly placed downspouts, lack of eaves trough and poorly designed valley drainage on second storey roofs can cause a waterfall effect that washes away the shingles granules over time. Aging and physical damage can also cause bare spots and loss of granules to your shingle. When the protective granules of a shingle are worn out the shingle then hardens under the exposure to heat and sun. Once this happens your shingle losses life expectancy and can become an entry point for water to get through.
- Broken or Missing Shingles
Broken or missing shingles weaken your roofs ability to shed water, thus leaving it vulnerable to water leaks.
- Buckling Shingles
Buckling shingles are waved distortions that run up a vertically up a roof slope and are easily visible to the human eye. Buckled shingles can easily be torn off under conditions of high winds and susceptible to water and ice damage.
- Damaged Flashings
Flashing can be found around skylights, valleys, eaves, rakes, wall details, stacks, and chimneys. All of which are subject to separation, lifting and dried out caulking. General expansion and contraction can cause these flashing details to lift and separate, causing the fasteners to become lose and the bottom- flashing to lift thus causing an entry point for water.
If you notice any of these signs to your roofing system you will need to get in touch with your certified roofing contractor to discuss what need to be done to protect your investment. As a leak in your roof doesn’t always have visible signs to the interior house; it can first cause insulation and structural damage.
