Protecting Your Home with Northwestern Ontario’s ONLY GAF Master Elite Contractor
Your roof is the most important component of your home's thermal envelope. In Thunder Bay, it isn’t just about aesthetics; it’s about resilience against heavy snow loads, rapid freeze-thaw cycles, and high-velocity winds. At JM Northshore Roofing, we provide residential roofing solutions built on 35 years of family-run expertise and the gold standard of industry certification.
The JM Northshore Material Advantage
We don’t believe in "one-size-fits-all." We select products engineered to survive the unique Northern Ontario climate.
Premium Asphalt Shingles
We prioritize asphalt shingles that offer high-performance lamination and wind resistance. Unlike budget-grade options, these provide:
-
Dimensional Durability: Multi-layered construction for better protection against impact and weather. -
Algae Resistance: Advanced coatings that prevent the streaking common in damp, northern environments.
-
Superior Warranty: As GAF Master Elite contractors, we provide the Golden Pledge warranty that covers the shingles, the entire roofing system, and workmanship for 25-30 years.
Classic Cedar Shakes
For homeowners who value timeless aesthetics, we offer premium cedar shakes. These are not merely decorative; when installed correctly with our signature ventilation techniques, they offer:
-
Natural Insulation: Superior thermal performance, which is critical during Thunder Bay winters.
-
Structural Longevity: Resistance to natural decay when properly maintained and vented.
-
Custom Craftsmanship: Our father-son team brings decades of experience to the precise, labor-intensive process of installing cedar, ensuring a water-tight, breath-taking result.
Our 5-Step Precision Roofing Process
- Comprehensive Inspection: We look beyond the surface. We assess your attic ventilation, structural decking, and flashing points to identify existing issues before they become emergencies.
- Tailored Material Strategy: Based on your home’s architecture and your goals, we recommend the specific product line, whether premium asphalt or cedar, that provides the best value.
- Site Protection & Preparation: We treat your property with respect. We manage the worksite to protect your landscaping, driveway, and home exterior, ensuring a clean and safe environment.
- GAF Master Elite Installation: We install the entire roofing system. This includes proper underlayment, starter strips, and ridge caps. Most importantly, we focus on proper ventilation, the key to preventing ice dams in our region.
- Final Quality Assurance: Our leadership team performs a rigorous final inspection, reviewing flashing, shingle alignment, and debris removal to ensure your 100% satisfaction.
Why Ventilation is the Key to Northern Roofing
One of the most common reasons roofs fail in Northwestern Ontario is poor attic ventilation. Without proper airflow, heat trapped in your attic melts snow on the roof surface, which then refreezes at the eaves, creating ice dams.
Our installation process prioritizes a balanced intake-and-exhaust ventilation system. This keeps your roof deck at the same temperature as the outside air, preventing ice buildup and significantly extending the life of your roofing materials.
Frequently Asked Questions (FAQ)
We perform an objective audit. If your roof is past its service life (20+ years for many asphalt roofs) or has structural damage, replacement is the safest route. If the damage is isolated (e.g., wind damage, small leaks), we will provide a repair plan that buys you more time.
Only the top 3% of roofers in North America achieve this. It confirms we are factory-certified, properly insured, and financially stable. It also allows us to offer the GAF Golden Pledge Warranty, which covers our workmanship for 25-30 years depending on your choice of shingles – the GAF Timberline HDZ or GAF Timberline UHDZ.
We are local experts. We will assess the condition and put forth the best decision to ensure longevity for your roof.
For most Thunder Bay homes, a full roof replacement is a multi-day process. We focus on quality over speed, ensuring that no step of the system is skipped, even if it adds time to the project.
