Your roof is a system where every component works together. We install and service all roofing components: decking, underlayment, flashing, vents, skylights, ice shields, and more. Integrated systems that protect Ottawa homes.
Many homeowners think of their roof as just the shingles. In reality, your roof is an integrated system where each component plays a critical role. When components work together properly, your home stays dry and protected for decades.
| Layer | Function |
|---|---|
| Roof Decking | Structural base for entire system |
| Underlayment | Secondary moisture barrier |
| Ice & Water Shield | Extra protection at eaves and valleys |
| Flashing | Directs water around penetrations |
| Roof Vents | Exhausts moisture from attic |
| Drip Edge | Guides water to gutters properly |
| Primary Roofing | Sheds water from above |
Roof Decking: The structural base layer that supports entire roof system and home structure

Your roof deck (typically plywood or OSB) is the structural foundation. It must be properly ventilated and protected from moisture. Poor deck leads to structural failure of entire roof.
If shingles leak (which they will eventually), underlayment is your second line of defense. Without it, water goes directly into your attic.
Ottawa's freeze-thaw cycles create ice dams. Water backs up under shingles at the eaves. Ice & water shield catches this water and directs it down and out, preventing interior damage.
Anywhere pipes, vents, or chimneys go through your roof, water can get in if flashing is improper. Proper flashing is critical at these penetration points.
Your attic needs both intake ventilation (through soffit vents) and exhaust ventilation (through roof vents). Proper ventilation prevents ice dams, removes moisture that causes mold, extends roof life, and improves energy efficiency.
Water running down your shingles needs to go into gutters, not behind them. Drip edge ensures this happens.
Ottawa's harsh climate demands proper component integration for reliable roof protection.
Ottawa's temperature swings and heavy snow create ice dam conditions. Without proper component integration, ice dams cause interior water damage every winter.
Water enters the smallest cracks and expands when frozen. This accelerates damage. Proper underlayment and ice shields catch water before it can do damage.
Ottawa snow can exceed 200 pounds per square foot. Your roof deck must be properly sized and supported. Poor decking under heavy snow causes structural failure.
Materials expand and contract dramatically from -30°C to +30°C. Flashing, drip edge, and vent installations must allow for this movement.
You need roof ventilation working year-round. Vents help in winter (prevents ice dams) and summer (exhausts heat from attic).
Summer humidity and spring melt create moisture that accumulates in attic if ventilation is inadequate. Proper venting and underlayment prevent this.
| Component | Lifespan | Signs of Failure |
|---|---|---|
| Roof Decking | 20-60 years | Soft spots, water stains, visible rot |
| Underlayment | 20-50 years | Water leaking through, visible deterioration |
| Ice & Water Shield | 20-30 years | Ice dam water entering interior |
| Flashing | 20-40 years | Water leaking around vents/chimneys/skylights |
| Roof Vents | 20-30 years | Visible deterioration, not drawing air |
| Drip Edge | 20-40 years | Water running behind gutters, deterioration |
| Asphalt Shingles | 15-25 years | Missing shingles, curling, granule loss |
Cause: Sealant failure, corrosion, improper installation
Solution: Resealing or replacement of flashing
Cause: Inadequate ice shield, poor ventilation
Solution: Upgrade ice shield, improve ventilation
Cause: Poor installation, age, wrong location
Solution: Verify location and airflow, replace if needed
Cause: Missing drip edge, improper installation
Solution: Install drip edge, verify gutter alignment
Cause: Poor ventilation, moisture accumulation
Solution: Improve ventilation, remove mold, address moisture
Cause: Age, water exposure, poor ventilation
Solution: Replace with quality underlayment when re-roofing
