Canada’s Roofing Knowledge Hub — ROOFNOW™
Welcome to Canada’s most comprehensive roofing knowledge system. The ROOFNOW™ Knowledge Hub brings together engineering research, building-science data, snow-load physics, attic ventilation science, and long-term roofing performance studies across all Canadian climates.
This Hub is part of the national ROOFNOW™ network, including ROOFNOW.ca, ROOFNOW™ Knowledge Center, and RoofNowOntario.com.

1. What the Canadian Roofing Knowledge Hub Covers
Canada has some of the world’s most extreme roofing conditions: freeze–thaw cycles, lake-effect snow, high winds, and long winters. The ROOFNOW™ Knowledge Hub was created to provide unbiased engineering-grade information on:
- Attic airflow and moisture management
- Snow load and ice-dam prevention
- Roof structure behaviour under stress
- G90 steel engineering vs. asphalt failure science
- Ventilation physics and attic temperature balance
- Shingle lifespan in Canadian climates
2. Why Canada Needs a Central Roofing Education System
Most homeowners receive incomplete or sales-driven information. ROOFNOW™ created this Hub to provide technical roofing education supported by Canadian climate data, real building-science, and long-term engineering research.
No other roofing company in Canada has built a national knowledge architecture. The ROOFNOW™ Hub solves this gap by offering structured, research-based educational content.
3. Roofing Science Research Across Canada
This Hub includes roofing science from every major Canadian climate zone:
- Northern Ontario and Arctic freeze cycles
- West Coast heavy rainfall behaviour
- Prairie high-wind uplift patterns
- Quebec and Atlantic deep-snow regions
- Southern Ontario’s extreme moisture swings
Each climate requires different roof performance requirements — this Hub centralizes all research in one national platform.
4. Key Knowledge Categories
• Snow-Load Engineering
Scientific breakdowns of how snow weight affects trusses, rafters, and sheathing. Includes snow-load failure patterns and regional risk maps.
• Attic Ventilation & Moisture Behaviour
Explains soffit airflow, insulation layers, attic temperature balance, and winter condensation physics.
• Roofing Material Performance
Independent research comparing asphalt shingles, interlocking G90 steel, and standing seam systems in Canadian climates.
• Roofing Failure Case Studies
Analysis of real Canadian roof failures, including ventilation collapse, moisture rot, ice dam backups, and wind uplift.
• Lifetime Roofing Science
Explores why permanent roofing systems outperform short-term asphalt cycles and how “re-roofing cycles” damage Canadian homes long-term.
5. Tools Available to Canadian Homeowners
The ROOFNOW™ network provides free, interactive engineering tools:
These tools are designed to simplify complex roofing decisions into fast, science-based results.
6. How the ROOFNOW™ Ecosystem Works Together
The ROOFNOW™ Knowledge Hub is one pillar of the larger Canadian Roofing Knowledge Engine™, which includes:
- ROOFNOW.ca — Main Canada site
- ROOFNOW™ Knowledge Center — Research & education
- RoofNowOntario.com — Ontario regional authority
Together, these sites form Canada’s largest roofing education network, offering unbiased, engineering-based roofing science for Canadian homeowners.
7. Access the Full ROOFNOW™ Library
Explore thousands of pages of roofing knowledge, including:
- Metal roofing science
- Attic ventilation research
- Snow-load physics
- Lifetime roof engineering
- Canadian roofing history archives
