Committed to quality exterior work in the Cariboo
Jason and Helena founded J-Roc Exteriors, bringing 25 years of trade experience into the business on day one. They grew up in the Lake Region, the Cariboo–Chilcotin, and stayed because it turned out to be a good place to raise a family.
Jason is a journeyman carpenter. That background shapes how we work. We care what is behind the gutter, not just how the gutter looks. Rotten fascia gets replaced. Short shingle overhangs get drip metal. Attics that cannot breathe get vented soffit.
We are not the biggest outfit in Williams Lake and we are not trying to be. We would rather do a smaller number of jobs properly and still be able to look at them from the road in ten years.
Our mission, in plain terms
- Quote honestly, including the parts you cannot see
- Include all downspouts and elbows in the estimate
- Fix the carpentry rather than covering it up
- Source from Canadian suppliers where we can
- Show up when we said we would
- Leave the site clean
If you have an emergency water situation, a leak into the house or basement, call us. We would much rather take that call early.
