About Tridextor
A reference site focused on roof inspection, repair fundamentals, and snow load management for residential properties in Canada.
Last updated: May 2026
Purpose
Tridextor covers the intersection of roof maintenance and Canadian winter conditions. The content focuses on technical topics: how roofs fail under snow and ice loads, what inspection looks like in practice, and what structural and thermal factors lead to recurring problems like ice dams.
The site is organised around informational articles rather than promotional content. There are no product recommendations and no service listings. The material is drawn from publicly available engineering standards, government climate data, and building code documentation.
Scope
Coverage is limited to residential roofing in the Canadian context. This includes all major roof types found on houses and low-rise residential buildings: sloped asphalt shingle, metal, wood shake, flat EPDM and modified bitumen, and low-slope built-up systems. Provincial climate differences are addressed where they affect inspection approach or structural risk.
The site does not address commercial or industrial roofing, nor does it cover topics outside the residential maintenance domain such as new construction structural engineering or municipal building permit processes.
Content Standards
All articles reference publicly available sources. Where figures or thresholds are cited, the originating document is linked. Calculations and code requirements are taken from the National Building Code of Canada (NBC 2020) or from federal government agencies including Environment and Climate Change Canada and Natural Resources Canada.
The site does not publish statistics, research findings, or technical specifications without traceable public sources. Where uncertainty exists, content uses neutral language rather than precise figures.
Disclaimer
Information on this site is for general reference only. Specific roof conditions, structural assessments, and repair decisions should be evaluated by a licensed roofing contractor, structural engineer, or home inspector with direct knowledge of the property. The site does not substitute for professional advice and does not represent the official position of any standards body or government agency.
Contact
Questions and corrections can be submitted through the contact form on the home page. Factual corrections with cited sources are reviewed and addressed as promptly as possible.
Editorial Review
Articles are reviewed against cited source material before publication. Technical claims are checked against NBC 2020 and federal agency publications.
Update Cycle
Content is reviewed and updated on a semi-annual basis, or sooner when relevant code updates or major climate data revisions are issued.
