Top 5 Signs You Might Need A New Shingle Roof
- Age: depending on the type of shingle used and the original installation techniques, if your roof is over 10 years old, you should be looking at new replacement options. Another good indication is if your roof was installed the same time as your neighbours and they’re replacing theirs, you should consider getting yours replaced as well
- Lifted Shingles: if possible, inspect your roof visually for signs of cupping or curling as this is an indication of an old, worn out shingle that should be replaced
- Missing Shingles: as a shingle ages, it becomes more brittle and loses its adhesion to adjacent shingles making it more susceptible to wind damage.
- Missing Granules: if you happen to notice an excessive number of granules in your eavestrough or in your downspout discharge, this is a sign that the UV rays have broken down the asphalt bonding the granules to the shingles leaving your shingles bare and vulnerable
- Roof Leaks: if you’re experiencing leaks, it may be an indication that your shingles have failed and broken down to the point where they are no longer watertight and should be replaced

- Age: depending on your current roofing material, if your roof is over 10 – 20 years old, it’s a good time to replace
- Membrane Failure: if you are experiencing roof leaks, it may be a sign that your membrane has reached its life expectancy and is deteriorating
- Uneven Roofing Surfaces: blisters and ridges are a sign that your roof is getting old or was incorrectly installed. These are caused by trapped moisture within the roof membrane and are an indication that the membrane and insulation is unstable
- Ponding Water: ponding water is often a sign of collapsed roofing insulation and collects debris which in turn clogs roof drains and roof drain strainers.
- Bare Patches or Exposed Membrane or Cracking (for mod-bit roofs): as the membrane wears, the harmful and damaging UV rays break down the asphalt causing the flood coat on top of the membrane to deteriorate which exposes and weakens the membranes and causes a modified bitumen roof to become brittle and crack
