Working in Lake Oswego

What's it like to renovate a Lake Oswego home?

Lake Oswego homes tend to share two things: real architectural ambition, and a lot of trees. Mature fir and maple canopy keeps roofs and siding shaded and damp, which accelerates moss growth and wears finishes faster than almost anywhere else in the metro. Materials here have to be chosen for that reality, not just for the brochure photo.

This is also a community that notices details. Designer shingle profiles, factory-finished Hardie siding, true divided-light windows, hardwood decking: when the standard is 'looks right from the street and up close,' the installation has to be as considered as the product. That kind of finish work is exactly where our crews spend their days.

We start every Lake Oswego project with a free consultation and a detailed proposal, and we back the work with manufacturer warranties and our own written workmanship guarantee.

Questions from Lake Oswego homeowners.

Do I need a permit to remove a tree in Lake Oswego?+
Yes, for any tree six inches or more in diameter measured at breast height. Lake Oswego's tree code runs through the Planning Department, and tree protection or removal applications go in alongside building permits. It matters for exterior work because the canopy that makes the city beautiful is also what keeps roofs damp and growing moss.
What does all the shade do to my roof?+
Mature fir and maple canopy keeps roof surfaces damp long after the rain stops, which accelerates moss growth and wears finishes faster than almost anywhere else in the metro. We spec algae-resistant shingles, zinc or copper strips at the ridge, and a straight answer on whether tree trimming belongs in the plan.
Who issues building permits in Lake Oswego?+
The City of Lake Oswego's Building Division. Oregon's statewide rule applies here: a like-for-like reroof usually needs no building permit, while structural work does, and when it does we pull it under our CCB number.
