Complete Attic Insulation & Roof Ventilation Solutions
At Chouinard Bros, we treat roof insulation and ventilation as one complete system. Proper insulation keeps heat where it belongs, while balanced ventilation allows moisture and excess heat to escape. When these systems work together, they protect your roof, lower energy costs, and improve comfort throughout your home.
Many roofing issues we see in Aurora homes—ice damming, condensation, mold, and premature roof failure—can be traced back to poor insulation, outdated ventilation, or both. Our job is to identify those weak points and correct them properly, not just mask the symptoms.
Whether your home is decades old or relatively new, we inspect your attic, calculate airflow requirements, and bring everything up to current Ontario Building Code standards.
Why Insulation and Ventilation Must Work Together
Insulation and ventilation are often misunderstood as separate upgrades. In reality, they rely on each other.
- Insulation slows heat loss and prevents warm air from entering the atti
- Ventilation removes moisture and regulates attic temperature year-round
- Together, they reduce ice damming, condensation, and structural stress
- Balanced systems protect roof decking, shingles, and attic framing
A well-designed system keeps your attic temperature close to the outdoor temperature in winter and prevents extreme heat buildup in summer.
50+ Years of Roofing and Building Science Experience
We’ve been serving homeowners across Aurora and the GTA for over 50 years. Over that time, insulation and ventilation standards have changed dramatically. Homes that once had 6 inches of insulation may now require 30 inches or more to meet modern code.
We’ve adapted through every change in materials, codes, and best practices. That experience allows us to spot problems quickly, explain them clearly, and install solutions that last.
Installation, Upgrades & Repairs
Not every home needs a full overhaul. We tailor our approach based on what your attic actually needs.
Our insulation and ventilation services include:
- Adding attic insulation to meet current code requirements
- Replacing contaminated or damaged insulation
- Correcting heat loss and moisture problem areas
- Installing or upgrading intake and exhaust roof vents
- Balancing airflow to prevent ice damming and condensation
- Fixing issues flagged by home inspectors or insurance providers
If pests, moisture, or settling insulation are present, we address those issues before installing new materials.
Code-Compliant and Warranty-Protected
Every insulation and ventilation install we complete is done according to Ontario Building Code and manufacturer specifications. This is critical not only for performance, but also for maintaining roofing and material warranties.
Our work is backed by a 10-year workmanship warranty, and we only use insulation and ventilation products that carry strong manufacturer warranties.
You get peace of mind knowing the system protecting your roof is built to last.

Our crews are fully trained, certified, and insured. We don’t subcontract critical work without oversight, and every project is inspected to ensure it meets our standards before completion.
- Certified installation protects your warranties
