Winter Roof Protection and Maintenance: Guide for Calgary Homeowners

Canadian winters, especially in Calgary, can be extreme and pose unique challenges for homeowners. With the frequent frost/freeze Chinook cycles, your roof is particularly vulnerable to damage.

This comprehensive guide will help you understand common winter roof issues, how to avoid them, and the importance of timely maintenance and repairs.

1. Common Winter Roof Issues:

a) Condensation:

• Caused by improper ventilation
• Can lead to mold and mildew growth
• Health hazard if left unchecked

b) Ice Damming:

• Occurs when snow freezes and blocks eaves
• Causes water pooling and potential leaks
• Can damage gutters and eavestroughs

c) Icicles:

• Result of clogged gutters and ice damming
• Pose safety risks to people and pets
• Can cause gutter damage due to excess weight

d) Leaking Flashings:

• Metal pieces around roof joints, vents, and chimneys
• Can weaken due to ice and snow buildup
• Lead to roof leaks if compromised

e) Heavy Snow and Ice Buildup:

• Weakens roof joints
• Causes leaks
• Risk of roof collapse in extreme cases

f) Wind Damage:

• Can tear off loose or damaged shingles
• May damage gutters and eavestroughs

g) Animal Intrusions:

• Pests seeking warm shelter in winter
• Can cause damage to roof and attic

2. Preventive Measures:

a) Proper Attic Insulation:

• Helps regulate home temperature
• Creates an air-tight seal

b) Attic Ventilation:

• Regulates airflow
• Prevents moisture problems

c) Regular Inspections:

• Identify vulnerable spots
• Prevent minor issues from becoming major problems

d) Gutter Maintenance:

• Regular cleaning to prevent ice damming
• Consider installing heated gutter cables or snow-prevention netting

e) Tree Maintenance:

• Trim branches near the roof to prevent damage during storms

f) Professional Snow Removal:

• Consider hiring a service for heavy snowfall

3. Signs of Roof Stress:

• Doors becoming difficult to open or close
• Creaking and popping sounds from the roof
• Formation of cracks and leaks

4. Importance of Timely Repairs:

As emphasized by Mike Holmes, a renowned home improvement expert:

• Address roofing issues before winter sets in
• Avoid rushed jobs in cold weather
• Prevent further damage and costly repairs

5. Re-Roofing Considerations:

a) Asphalt Shingles:

• Most common and cost-effective option
• Not ideal for winter installation (become brittle in cold)
• Signs of wear: granule loss, bare spots, torn or missing shingles, buckling or curling

b) Metal Roofing:

• Longer lifespan (about 50 years)
• Environmentally friendly and fire-resistant
• Higher upfront cost but more cost-effective long-term

6. Installation Tips:

• Remove old shingles before installing new ones
• Use high-quality underlayment (self-adhering ice and water shield)
• Ensure proper installation for warranty validity
