Roofs – helpful tips

Inspect your roof at least twice a year, in wet and dry weather.

• In a storm, does rainwater overflow gutters? Is debris clogging them?
• Are downspouts directing water away from building?
• Are there leaks or damp spots in the attic?
• After the storm is over, do pools of water remain?
• Are there loose shingles or signs of damage?
• Are tree branches rubbing and damaging the roof?

Temporary repairs are better than doing nothing.

• Patching can prevent further damage to the building.
• Repair only the problems: don’t replace intact, functional roofs.

Replacement roofs should match the original material, colour and design.

• If matching is impossible, review other options carefully.
• Consider compression/expansion potential, longevity, compatibility, and price.
• Consult municipal planners if building is designated or in a Heritage Conservation District.

Heritage roofs need to breathe – don’t over-insulate.

• Improper insulation can damage roof materials.
• Look for uniform build-up of snow.
• Irregular snow melting, icicles and ice dams suggest insulation problems.
• Check the Region of Waterloo Practical Guide to Insulation [PDF].
