Calgary Roof Repair | Common Roofing Problems in Calgary and How to Fix Them

Calgary Roof Repair | Calgary’s unique weather conditions, ranging from harsh winters to stormy summers, can take a toll on the roofs of homes and businesses. Understanding common roofing problems and how to address them can help homeowners maintain their roofs and extend their lifespan. In this blog, we’ll explore some typical roofing issues faced by Calgarians and provide practical solutions for each.

1. Ice Dams

Problem: Ice dams form when the snow on a roof melts and refreezes at the edges, creating a barrier that prevents proper drainage. This can lead to water seepage into the home, causing damage to walls, ceilings, and insulation.

Solution: To prevent ice dams, ensure your attic is well-insulated and ventilated to keep the roof temperature consistent. Installing ice and water shields along the roof edges can also provide extra protection. Regularly removing snow from your roof can further reduce the risk.

2. Shingle Damage

Problem: Shingles can be damaged by high winds, hail, and UV exposure, leading to cracks, curling, or complete detachment. Damaged shingles expose the roof to leaks and other issues.

Solution: Regular roof inspections can help identify damaged shingles early. Replace any missing or damaged shingles promptly. Consider using high-quality, weather-resistant shingles designed to withstand Calgary’s climate.

3. Roof Leaks

Problem: Leaks are one of the most common roofing issues and can be caused by various factors, including damaged shingles, flashing, or skylights. Leaks can lead to significant water damage if not addressed promptly.

Solution: Locate the source of the leak by inspecting the attic and roof. Repair or replace damaged roofing materials and ensure proper sealing around roof penetrations such as chimneys and vents. Using a professional roofing service can ensure a thorough and effective repair.

4. Flashing Failures

Problem: Flashing, the material used to seal joints and prevent water intrusion, can deteriorate over time. Poor installation or weathering can lead to flashing failures, resulting in leaks.

Solution: Regularly inspect flashing around chimneys, skylights, and valleys for signs of damage or wear. Re-seal or replace faulty flashing as needed. Using high-quality materials and proper installation techniques can prevent future issues.

5. Gutter Problems

Problem: Clogged or damaged gutters can prevent proper water drainage from the roof, leading to water pooling and potential roof damage. Gutters can also be damaged by ice, wind, or debris.

Solution: Clean gutters regularly to remove leaves, twigs, and other debris. Repair any damaged sections and ensure gutters are securely fastened to the roof. Installing gutter guards can reduce the frequency of cleaning.

6. Moss and Algae Growth

Problem: Moss and algae growth, especially on shaded roofs, can retain moisture and cause shingle deterioration. This can lead to leaks and reduced roof lifespan.

Solution: Remove existing moss and algae using a specialized cleaning solution and a gentle brush. Trim overhanging branches to reduce shade and improve air circulation. Consider installing zinc or copper strips along the roof ridge to prevent future growth.

7. Poor Ventilation

Problem: Inadequate roof ventilation can lead to moisture buildup in the attic, causing mould growth and increased temperatures. This can affect the roof’s structural integrity and energy efficiency.

Solution: Ensure your attic has proper ventilation, including soffit vents, ridge vents, and gable vents. Proper ventilation helps regulate temperature and moisture levels, extending the roof’s life and improving home comfort.

8. Tree Damage

Problem: Overhanging branches can scrape against the roof, dislodging shingles and creating entry points for water. Fallen branches can cause significant damage during storms.

Solution: Regularly trim trees near your home to prevent branches from touching the roof. Remove any dead or weak branches that could fall during a storm. Maintaining a safe distance between trees and the roof can minimize the risk of damage.

9. Hail Damage

Problem: Hailstones can cause significant damage to roofing materials, leading to dents, cracks, and holes. This damage can compromise the roof’s ability to protect your home from water and weather elements.

Solution: After a hailstorm, inspect your roof for signs of damage. Look for dents in metal roofing, cracked shingles, and bruising. Contact a professional roofing contractor to assess and repair any hail damage to ensure your roof remains watertight.

10. Aging Roof

Problem: All roofs have a finite lifespan, and over time, they will naturally degrade and lose their effectiveness. An aging roof may show signs of wear such as granule loss, curling shingles, and general brittleness.

Solution: Regular maintenance can extend the life of an aging roof, but eventually, replacement will be necessary. Schedule a professional inspection to determine the roof’s condition and plan for replacement before significant issues arise.


Maintaining a roof in Calgary requires vigilance and proactive care due to the region’s challenging weather conditions.
