ROOF
EXPANSION &
CONTRACTION
ONTARIO
Ontario roofs constantly expand and contract through heat, cold, snow, ice, and freeze-thaw cycles. Over time, this movement can crack shingles, loosen flashing, create leaks, and weaken aging roofing systems.

Why roof expansion and contraction damages Ontario homes.
Ontario weather creates constant roofing movement. Hot summers, freezing winters, rapid spring thaws, and fall temperature swings force roofing materials to expand and contract repeatedly. Over time, this movement weakens shingles, flashing, valleys, fasteners, and roof edges.
Cracked Shingles
Repeated temperature movement can make aging asphalt shingles brittle, cracked, curled, and vulnerable to leaks.
Flashing Separation
Expansion and contraction can slowly loosen flashing around chimneys, vents, skylights, and roof transitions.
Hidden Leak Paths
Small roof openings caused by movement can allow snow melt, rain, and moisture to penetrate the roofing system.
Built for Ontario freeze-thaw cycles and weather extremes.
ROOFNOW™ specializes in permanent interlocking metal roofing systems designed for Ontario homeowners looking for stronger long-term protection against roof movement, temperature swings, snow loads, moisture, and repeated asphalt roof failure.
