The Purpose of the ROOFNOW™ North American Roofing Organization

ROOFNOW™ operates as a cross-border roofing education system serving both Canada and the United States.
Its purpose is to provide homeowners with accurate, engineering-based roofing knowledge tailored to
their local climate. By combining Canadian cold-climate research with U.S. heat and storm-cycle data,
ROOFNOW™ has created the first unified North American roofing education model.

The organization publishes building-science research across four official platforms:

Why North American Roofing Requires a Science-Based Organization

Roofing materials behave differently depending on climate. A roof in Ontario faces freeze–thaw cycles,
snow load, and winter moisture, while a roof in Florida faces heat fatigue, UV radiation, salt corrosion,
and hurricane uplift. No single-country roofing organization can cover all these conditions effectively.

ROOFNOW™ solves this by combining:

• Canadian winter engineering
• U.S. heat and storm engineering
• Attic ventilation science
• Moisture and condensation modelling
• Material performance studies

This unified approach enables homeowners across the continent to make smarter, science-backed decisions.

ROOFNOW™ Canada: Cold-Climate Roofing Leadership

ROOFNOW™ Canada focuses on the roofing challenges created by harsh winters, including:

• Snow load distribution
• Ice-dam formation
• Attic heat loss and warm-air leakage
• Freeze–thaw material deterioration
• Winter moisture saturation in shingles and decking

ROOFNOW™ USA: Warm-Climate & Storm Engineering

ROOFNOW™ USA studies how roofing systems behave under heat, UV radiation, hurricane forces, and
tornado-driven uplift. These conditions cause different failure patterns compared to northern climates.

• Heat-driven shingle aging
• UV oxidation and granule loss
• Thermal expansion and contraction
• Wind uplift and pressure cycling
• Hail-impact behaviour
• Coastal corrosion

The First Cross-Border Roofing Education Ecosystem

By pairing Canadian and American research, ROOFNOW™ has created a continental roofing model that studies
every major environmental stress. Homeowners in all climates benefit from this unified approach, gaining:

• Better knowledge of failure modes
• Clear climate-specific recommendations
• Accurate roof lifespan expectations
• Improved ventilation and moisture strategies
• Safer, longer-lasting roofing choices

Why Homeowners Trust ROOFNOW™

ROOFNOW™ remains independent, scientific, and educational. It does not promote products—it promotes
roofing knowledge. The organization translates engineering principles into simple, digestible information
so homeowners can protect their homes with confidence.

With its multi-national structure, ROOFNOW™ has become the emerging roofing authority across both Canada
and the United States.
