CORNWALL · EASTERN ONTARIO

Roof preservation in Cornwall.

NanoGuard Solutions serves Cornwall homeowners and the surrounding townships, plus commercial and industrial building owners in eastern Ontario. Eastern Ontario roof checks are handled by our regional partner based in Ottawa.

Cornwall homeowners can book a free roof check with our crew. We assess the roof on site, show you the photos and give you a clear recommendation and price.

Fortify protects sound asphalt shingles. Revive restores flexibility to weathered shingles. Both start with the condition of the roof you already have, not an assumption that it needs replacing.

HOMES IN CORNWALL

Condition decides, not postcode.

Cornwall has older homes near the downtown and river, post-war neighbourhoods and newer subdivisions to the north. Older homes may have layered roofing or past repairs worth mentioning before the roof check.

QUESTIONS WE HEAR

Is Cornwall too far for a free roof check?: No. Cornwall is in our service area and the roof check is free.
What if my roof isn't a candidate?: We tell you plainly. If replacement is the right call, you'll hear it at the roof check.

A PRACTICAL ROOF CHECK

What to look for from the ground.

Granules collecting in eavestroughs or at downspouts.
Curling, cupping or cracked shingles, especially on sun-facing slopes.
Ice-dam marks or staining at the eaves after winter.
Moss, algae streaks or lifted tabs after strong wind.
Attic signs: damp insulation, daylight or stains on the underside.

Stay off the roof. These are prompts for an assessment, not a diagnosis. Read the full guide.
