Spring inspection (April–May): Walk the roof to identify winter damage, membrane cracks, opened seams, displaced flashings, and ice dam residue near drains. Clear all drains before spring rainfall season. Fall inspection (October): Inspect for summer UV damage and ensure drains are clear before freeze-up. Address any issues before the first hard freeze makes them worse.
What a Professional Flat Roof Inspection Covers
A Cossette professional inspection goes beyond a visual walkover. The roofer assesses: membrane condition across the entire surface and at seams; flashing integrity at all penetrations, walls, and perimeter edges; drain function and flow; deck condition where accessible; ponding patterns from prior rainfall; and any areas showing blistering, cracking, or granule loss. A written report is provided.
When Early Replacement Is Warranted in Gatineau
Replace sooner than the 30–35 year expected lifespan when: the same area has been repaired twice or more; soft deck sections are found during inspection; a new addition or renovation is being attached to the existing roof; or the homeowner is planning a sale and the roof condition will affect negotiations. A failing flat roof is one of the most common deficiencies discovered during home inspections in the Gatineau area.
DIY vs. Professional Inspection for Gatineau Flat Roofs
Homeowners can perform basic visual checks from a ladder, looking for obvious splits, ponding areas, or debris around drains. But a professional inspection from Cossette provides access to the full roof surface, trained assessment of seam and flashing conditions, and a written report that documents the roof’s condition for insurance or resale purposes. A professional inspection is particularly valuable for roofs over 15 years old.
Frequently Asked Questions
How much does a flat roof inspection cost in Gatineau?
Cossette provides free flat roof inspections as part of an estimate for any repair or replacement work. Standalone inspection pricing varies — contact Cossette at 819-777-7177 for current rates.
Can I walk on my flat roof in Gatineau for inspection?
A flat roof can generally support careful foot traffic on sound membrane sections. Avoid walking on areas with visible blistering or soft spots, which may indicate saturated insulation below. Always use appropriate footwear (soft-soled) and avoid sharp tools that could puncture the membrane.
What should I do after a major hailstorm to check my flat roof in Ottawa?
After a significant hailstorm, visually inspect drains for granule accumulation (sign of cap sheet damage) and check for any new water stains inside. Contact Cossette for a professional post-storm inspection if you suspect impact damage — hail can crack the cap sheet in ways that are not immediately visible from the ground.
