About WestGrove Home
WestGrove Home is a reference site focused on roof snow load awareness and ice dam prevention for residential properties in Canada. The content covers the physical mechanics of ice dam formation, safe snow removal approaches, and the role of attic ventilation in cold-climate roof performance.
What This Site Covers
The site addresses three interconnected topics that affect Canadian homeowners during winter months:
- Ice dam formation: How the temperature differential between the heated upper roof and the cold eave creates the conditions for melt-refreeze cycles and water infiltration.
- Snow load and removal: When accumulated roof snow may warrant intervention, how to assess load conditions from ground level, and which removal methods minimize risk to the roof structure and to personal safety.
- Attic ventilation: The role of soffit-to-ridge airflow in keeping roof deck temperatures close to outside air, and what the National Building Code of Canada specifies for residential attic ventilation ratios.
Scope and Limitations
The content on this site is educational in nature. It draws on publicly available guidance from sources including Natural Resources Canada, the National Research Council of Canada, and Environment and Climate Change Canada. It is not a substitute for professional assessment by a licensed contractor, structural engineer, or building scientist.
Roof and attic conditions vary significantly by building age, construction type, geographic location, and maintenance history. General information about ice dam mechanics or ventilation ratios may not apply to specific situations without professional review.
