Your roof is your home’s first line of defense against the elements—but over time, the weather it shields you from can also become its biggest threat. Rain, wind, snow, sun, and even temperature changes can all take a toll on your roofing system.
Understanding how different weather conditions affect your roofing services calgary can help you take preventative steps and schedule timely maintenance, saving you money and stress in the long run.
☀️ Heat and Sun
What Happens:
Prolonged exposure to UV rays can cause roofing materials—especially asphalt shingles—to dry out, fade, crack, and become brittle over time. Extreme heat can also warp or curl shingles and accelerate the aging process.
What to Watch For:
Faded or discolored shingles
Cracked or brittle shingles
Peeling sealants or flashing
Pro Tips:
Choose UV-resistant roofing materials in sunny climates
Ensure proper attic ventilation to minimize heat buildup
Schedule inspections before and after peak summer months
?️ Rain and Moisture
What Happens:
Heavy or consistent rain can reveal vulnerabilities in your roof’s sealing. Poor drainage or damaged flashing can lead to leaks, rot, and mold growth—both on your roof and inside your home.
What to Watch For:
Leaks or water stains on ceilings
Moss or algae on the roof
Gutter clogs or overflowing water
Pro Tips:
Clean gutters regularly
Inspect flashing and sealant around chimneys and vents
Trim nearby trees to reduce moisture buildup
?️ Snow and Ice
What Happens:
Snow accumulation adds weight, and freezing/thawing cycles can cause ice dams—ridges of ice that block melting snow from draining. This can force water under your shingles and into your home.
What to Watch For:
Icicles hanging from the roofline
Ice dams on eaves and gutters
Attic frost or condensation
Pro Tips:
Improve attic insulation and ventilation
Use a roof rake to remove snow after storms
Install ice and water shields in vulnerable areas
? Wind
What Happens:
High winds can lift or tear off shingles, damage flashing, and loosen gutters. Wind-driven debris can also puncture or scrape roofing materials, compromising their integrity.
What to Watch For:
Missing or misaligned shingles
Debris on your roof or in your yard
Damage to soffits, fascia, or gutters
Pro Tips:
Use roofing materials rated for high winds
Secure loose shingles or flashing
Schedule post-storm inspections
?️ Temperature Fluctuations
What Happens:
Rapid temperature changes cause materials to expand and contract. Over time, this weakens the roofing system, leading to cracks and premature wear—especially in climates with large day-to-night temperature swings.
What to Watch For:
Small cracks in shingles or flashing
Separated seams or joints
Curling or buckling shingles
Pro Tips:
Choose flexible, durable roofing materials
Seal all joints and seams properly
Monitor older roofs closely for signs of fatigue
