TOTAL SYSTEM COVERAGE
A Multi-Layered Defence Against Winnipeg Weather

Shingles
Choose from Good, Better, or Best styles across CertainTeed's Landmark Series — dozens of colours and profiles to match any home.

Starter Shingles
Engineered to work in tandem with your shingles at the eaves and rakes — improving sealing performance exactly where wind and water hit hardest.

Waterproofing Underlayment
Self-adhering underlayment installed at your roof's most vulnerable areas — valleys, eaves, and penetrations. Your first line of defence against wind-driven rain and ice dams.

Water-Resistant Underlayment
A protective layer across the full roof deck that acts as a secondary barrier against leaks if shingles are ever lifted or damaged.

Ventilation
Ridge vents combined with intake vents keep air flowing under your roof deck year-round — cooler in summer, drier in winter, and significantly longer-lasting overall.

Hip & Ridge Caps
A clean, finished look at every peak and valley — and a watertight seal at the areas where two roof planes meet.

WATCH FOR THESE WARNING SIGNS
Signs Your Shingle Roof Needs Attention

Winnipeg’s climate is brutal on shingles. Your roof faces a constant cycle of extreme cold, ice dams, hailstorms, and intense UV exposure that accelerates wear and tear. While some damage is obvious after a storm, many shingle failures—like brittle granules, hidden seal failures, or slow-moving leaks—begin in areas you can't see from the driveway. Because Manitoba's extreme freeze-thaw cycles can force water under even the best shingles, minor aging can quickly escalate into major structural rot if your roof isn't professionally maintained.

Warning Signs Your Shingle Roof is Failing:

❌ Missing, cracked, or curling shingles
❌ Granule loss visible in gutters or downspouts after rain
❌ Daylight visible through attic boards when you look up inside
❌ Sagging or drooping roof sections
❌ Water stains on interior ceilings or walls
❌ Roof is 20+ years old — even if it looks okay from the ground
❌ Ice dam formation along eaves in winter
❌ Neighbourhood Roof Cycles: Most homes in a subdivision are built at the same time. If your neighbors are replacing their roofs, yours is likely reaching its natural expiration date

Not sure if you need a repair or a full replacement? We’ll provide a free, honest assessment of your roof’s condition. Often, a targeted repair can significantly extend your roof's life—we’ll give you a straight answer with zero pressure.
