Calgary homeowners, make sure your winter roof is prepared to protect your property from heavy snow, ice, and freezing temperatures.
Which, without proper maintenance, puts your roof in jeopardy for leaks, ice dams, and expensive repairs.
From inspecting shingles to cleaning gutters, here are key steps to fortify weak spots before winter hits.
Superior Roofing has you covered with peace of mind during Alberta’s harsh, cold season.
Assess Your Roof’s Health
Winterizing your roof for Calgary’s weather starts with a quality health check. As snow, ice, and temperature changes will only make problems worse, catching them early is essential. Follow these steps to ensure your roof is ready for the season ahead:
- Examine shingles or tiles. Check shingles, metal panels, or slate tiles for cracked, curling, or missing damage. Asphalt shingles, typical in Calgary, are especially susceptible to degeneration from UV rays and freeze-thaw cycles. Even small problems — a single torn shingle — can result in leaks or water damage as snow melts. Deal with these right away, or you’ll be looking at major repairs.
- Ventilation Check. Needless to say, proper roof ventilation is crucial for keeping air flowing and preventing moisture accumulation in your attic. Inadequate ventilation spells ice dam– with water backing up beneath shingles and leaking. Make sure your roof vents are free of debris and operating properly. This control stabilizes indoor temperatures to lower your heating bill.
- Inspect Your Insulation. Inspect your attic insulation — make sure that it’s adequate and evenly distributed. Holes or thin areas cause heat to leak, resulting in inconsistent roof temperatures and ice dams. Insulation – step up the insulation if necessary to provide a uniform thermal barrier for winter.
- Scan for structural problems. Look for sagging, cracks, or loose sections. Winter storms cause a lot of extra weight on your roof, so the structure is key. Don’t wait! Sagging is a disaster waiting to happen, and the worst snow loads only get heavier with time.
- Check up after the snow! Schedule a mid-winter inspection following any heavy snow to identify fresh problems such as ice dams, leaks, or stress points. Routine inspections minimize hazards and enable proactive patch-ups before issues escalate.
The Pre-Winter Cleanup
Prepping your roof for Calgary’s brutal winter begins with the annual pre-winter cleanup. It’s part of the pre-winter cleanup that will set your roof, gutters, and attic up to battle snow, ice, and winds. Forgetting this process can cause expensive repairs or damage later in the season.
Key Tasks for a Pre-Winter Cleanup
- Clear Rooftop Snow and Moss: Use a roof rake to gently remove any early snow buildup or moss on your roof. Snow or moss moisture can penetrate shingles and lead to extended damage. Don’t hurt those shingles!
- Trim Overhanging Branches: Tree branches hanging over your roof can be a hazard during winter storms. Strong winds or snow can send weak branches down onto shingles, gutters, or even the roof. Pruning these branches diminishes the risk greatly.
- Inspect and Clean Gutters and Downspouts: Clogged gutters are a common cause of ice dams, which can lead to water pooling and leaking into your home. Blow out leaves, dirt, and debris from gutters and clear downspouts. This drains water properly, avoiding winter water damage.
- Examine Shingles and Roof Valleys: Check for missing, damaged, or improperly installed shingles, as well as granule loss. Roof valleys, the areas where two slopes come together, are especially susceptible to deterioration and moisture accumulation. Make certain they’re free of debris and in good repair.
- Check the Attic: Inspect for signs of animals, as they can damage insulation or create entry points for water. Now is a good time to add insulation to your attic and provide ventilation to avoid ice dams and help keep your home warm.
Doing so doesn’t just safeguard your roof, it sidesteps typical winter roofing issues.
Fortify Against Ice Dams
Ice dams are a common winter headache in Calgary when melting snow refreezes at the edges of roofs. To prevent them, you need to fortify your roof and home with the right insulation, sealing, and protective materials.
Attic insulation is your first line of defense. Poor insulation lets heat escape to warm your roof, melting snow, which then refreezes around the edges. Target R-38 at a minimum, with R-49 or better being optimal for Calgary’s brutal winters. Improving insulation reduces ice dam potential and can save up to 15% on energy bills, too.
Sealing gaps and cracks is just as important. If you’ve got warm air leaking through your roof, it can speed up snowmelt at an alarming rate. Inspect for leaks around vents, chimneys, and other penetrations and seal with caulking or spray foam. This step keeps attic temperatures consistent, a vital aspect in preventing ice dams.
Waterproofing or underlayment provides an additional safety net. Ice and water shield membranes, installed beneath shingles at roof edges and valleys, provide a barrier to prevent leaks if ice dams form. Though these materials can add to initial expenses, their longevity and efficacy make them well worth the investment, particularly in a freeze-thaw climate such as Calgary.
Here’s a quick comparison of methods to combat ice dams:
| Method | Pros | Cons |
| Attic Insulation | Energy savings reduce ice dams | Requires upfront investment |
| Sealing Roof Gaps | Improves efficiency, affordable | Time-consuming to inspect |
| Waterproofing Materials | Prevents leaks, long-lasting protection | Higher upfront cost |
Other precautions are to clean gutters twice a year for good drainage, check flashings for deterioration, and carefully shovel snow if it’s more than six inches deep. Properly cared for shingles reduce ice dam hazards by 50%.
Brace for Calgary Snow Damage
Calgary’s brutal winters, with massive snowfalls and unexpected storms, can devastate roofs without the right precautions. Getting your roof in shape early and shoring it up against damage is key to safeguarding your home and your wallet.
Tips to Strengthen Your Roof
- Inspect Insulation and Ventilation: Poor insulation and inadequate ventilation lead to heat buildup, increasing the risk of ice dams. Test for water damage in insulation and allow for proper airflow to avoid these.
- Clean Gutters Thoroughly: Blocked gutters trap water, which freezes and forms ice dams. Clear debris and check for wear to ensure proper drainage.
- Upgrade to Winter-Resistant Materials: Consider durable options like asphalt shingles, metal roofs, or high-quality membranes. These materials are better suited to Calgary’s heavy snow and freezing temperatures.
- Schedule Roof Inspections: A professional inspection in early fall can identify weak spots, ensuring repairs are made before the first snowfall.
- Prompt Snow Removal: Snow accumulation exceeding 30 cm (about 1 foot) creates significant strain. Clear your roof as soon as snow accumulates, especially before new snowfall.
Unbearable weight can cause structural stress or roof collapse. A roof rake or professional help ensures safe snow removal without damage.
Fortify your roof with storm-resistant materials and annual maintenance, and save yourself from down-the-line disasters.
The Chinook Effect on Roofing
It’s a sort of weather phenomenon unique to Calgary and other regions near the Rockies – sudden, dramatic temperature increases during winter. Though this warm wind breathes sweet relief from the cold, it is a curse to roofs. Chinooks and fast temperature changes can cause damage, and homeowners should stay on top of it.
- Thermal Shock Damage: Chinooks cause roofing materials to expand and contract quickly due to temperature swings, which can lead to thermal shock. Asphalt shingles, especially, can become brittle and crack, thereby reducing their lifespan. Homeowners should check for signs of cracking or curling shingles.
- Freeze-Thaw Cycles: The frequent melting and refreezing of snow during Chinooks can create ice dams along roof edges and valleys. Ice dams don’t just prevent proper drainage; they can cause water to seep beneath shingles. Check these for wear, like dislodged granules or water stains, and make sure gutters are clear as well, so they don’t add any extra strain to the roof.
- Material Selection: Choosing resilient roofing materials is crucial in Chinook-prone areas. Fiberglass-reinforced asphalt shingles or synthetic alternatives can better withstand temperature fluctuations. Metal roofing, which is notably strong and resistant to expansion and contraction, is another great option for Calgary homeowners experiencing Chinooks.
- Adhesive Bonding: Rapid temperature changes can weaken roofing adhesives, causing shingle layers to lift or separate. Once winter inspections, inspect for any loose or misaligned shingles. Get on top of these before they cause any more damage.
- Professional Inspections: Given the unique challenges posed by Chinooks, roofs in Calgary require more frequent inspections. An experienced professional can spot weak points, suggest suitable materials, and make sure installations are properly sealed to resist these forces.
