🔑 What to Look For in a Roof Replacement

🧱 1. Quality of Shingles

Not all shingles are created equal:

📉 3-Tab Shingles → budget-friendly, shorter lifespan

📈 Architectural Shingles → more durable, better curb appeal, 25–40 yr warranties

🌟 Premium Shingles → algae-resistant, impact-resistant, enhanced colour options

👉 The right choice balances budget, appearance, and longevity.

🛡️ 2. Underlayments & Waterproofing

Shingles are only the top layer. A strong roof system includes:

🧊 Ice & Water Shield (mandatory along eaves & valleys in Ontario)

🪶 Synthetic Underlayment (longer lasting than felt)

💧 Drip Edge & Flashing (directs water away from fascia & siding)

These hidden layers = leak prevention + peace of mind.

👷 3. Contractor Credentials

Roofing is dangerous — hire only insured & trained professionals:

📋 Liability insurance & WSIB coverage (protects you if accidents happen)

🧗 Working at Heights training (required by Ontario law)

🔧 Proper harnesses, tools & equipment

🏆 Certified installers (to keep manufacturer warranties valid)

⚠️ A “cheap” crew without these protections can cost you much more in the long run.

🌬️ 4. Ventilation & Finishing Details

A roof isn’t just about shingles — it has to breathe:

🌬️ Attic ventilation (ridge vents, soffit vents, or upgraded systems)

🔨 Correct flashing around chimneys, vents & skylights

🎯 Ridge caps for a clean, watertight finish

These details extend roof life by years.
