Maintenance tips

  • Have your roof inspected for cracks, breaks, and loose or missing shingles. Shingle roofs generally last 20 years depending on weather conditions and materials. Steel and metal roofs can last up to 50 years while slate can last up to 75 years.
  • Look for blockages, leaks and holes in rain gutters, downspouts and extensions.
  • Clear gutters and downspouts of debris such as leaves and dirt.
  • Make sure your downspouts are directed away from your home.
  • Make sure screw heads and fasteners are properly covered.
  • Inspect and seal chimneys, vents and skylights.

Outside walls, doors and windows

What causes water damage?

  • Weather-generated water, such as rain, or melting snow or ice, that seeps through walls and around openings.
  • Poor maintenance or failure of water-proofing of external walls.

Maintenance tips

  • Assess glazing, weather-stripping, door and window seals, and other exterior elements for damage.
  • Look for water stains around windows and doors, and repair or replace weather barriers, if necessary. This crucial point of water access is often poorly installed during home construction.
  • Repair or replace caulking around windows and doors to make water-tight.
  • Check that exterior siding is not missing screws, which can create openings for water.
  • Keep any source of water, such as snow, away from your home’s exterior walls.
  • Shut off exterior water faucets during the winter to prevent it from freezing.
