Common Winter Roof Repairs: Addressing Issues Specific to Metal Roofing

Winter in Ottawa can be a challenging season for homeowners, especially regarding roofing. While metal roofing is known for its durability and long lifespan, they are not immune to cold weather’s challenges. 

As experts in metal roofing, we at Stewart Roofing understand the importance of protecting your home during winter. Here, we’ll explore some of the most common winter roof repairs specific to metal roofing and how we can help you address them efficiently and effectively.

Ice Dams and Snow Build-Up

One of the primary issues we see with metal roofs during winter is ice dams and snow accumulation. Metal roofing is excellent at shedding snow, but improper installation or insufficient insulation can lead to ice dams, which occur when snow melts and refreezes near the roof edges. This can cause water to back up under the roofing material, leading to leaks and potential structural damage.

How We Help:

• Inspections: We offer thorough inspections to identify vulnerable areas where ice dams will likely form.
• Solutions: We can mitigate this problem by installing snow guards, improving ventilation, and upgrading insulation.

Thermal Expansion and Contraction

Metal roofing naturally expands and contracts with temperature changes. During Ottawa’s frigid winters, this process can loosen fasteners, create gaps in seams, and even cause noise issues.

How We Help:

• Routine Maintenance: During regular inspections, we check for loose fasteners and tighten them as needed.
• Seam Repairs: Our team ensures that seams and panels are secured to prevent gaps that could lead to leaks.

Condensation Problems

In winter, warm indoor air can rise and meet the cold surface of your metal roofing, causing condensation. If not addressed, this moisture can lead to mould, mildew, and even structural rot.

How We Help:

• Ventilation Upgrades: Proper attic ventilation is crucial for reducing condensation, and we specialize in installing systems that keep air flowing efficiently.
• Barrier Installation: We can add vapour barriers to prevent moisture from seeping into the roof structure.

Corrosion and Rust Spots

Although modern metal roofs are coated to resist rust, prolonged exposure to snow and ice can wear down this protective layer, leading to corrosion over time. Salt used for de-icing can also accelerate rusting if it comes into contact with your roof.

How We Help:

• Protective Coatings: Our team can apply specialized coatings to reinforce the existing protection on your metal roof.
• Corrosion Repairs: We remove rust spots and treat affected areas to prevent further damage.

Loose or Missing Flashing

Flashing seals joints and edges and can become loose during the winter due to wind, snow, and ice. When flashing is compromised, water can seep into your home, causing leaks and interior damage.

How We Help:

• Inspection and Replacement: We inspect all flashing around chimneys, vents, and skylights and replace any that show signs of wear.
• Reinforcement: We use high-quality materials that withstand Ottawa’s harsh winter conditions to ensure durability.

Clogged Gutters

Even with metal roofing, clogged gutters can lead to significant problems. Snowmelt can refreeze in clogged gutters, creating ice dams and adding unnecessary weight that strains your roof.

How We Help:

• Gutter Cleaning Services: We clean out gutters to ensure smooth drainage.
• Gutter Guards: Installing guards prevents debris from accumulating, reducing maintenance needs.

Wind Damage

Ottawa’s winter storms can bring strong winds that may loosen panels or fasteners on metal roofing. This can leave sections of your roof exposed to further damage.

How We Help:

• Fastener Inspection: We inspect and replace damaged or missing fasteners.
• Storm-Ready Reinforcements: Our team ensures your roof is secured against future storms.

Snow Slide Hazards

Metal roofs are great for shedding snow, but they can sometimes do so too quickly, creating hazards for people, pets, and property below. A sudden snow slide can also damage gutters and lower roof structures.

How We Help:

• Snow Guards: We install snow guards to control snow flow off your roof.
• Customized Solutions: Depending on the slope and layout of your roof, we offer tailored solutions to manage snow effectively.

Preventative Measures for Metal Roofs

The best way to handle winter roofing issues is to prevent them before they start. Here’s what we recommend:

• Schedule Pre-Winter Inspections: Let us inspect your roof before the snow arrives to catch potential problems early.
• Regular Maintenance: Routine check-ups ensure your metal roof stays in peak condition year-round.
• Invest in Quality Materials: If you’re considering a new roof, choosing high-quality metal and proper coatings will save you trouble in the long run.
