Extera Works

Ospreys had been nesting on a Cape roof. Extera Works custom-fabricated copper chimney caps to stop them, kept the owner posted with drone footage as the work went on, and came in on time and on budget. That is the range here: shingles on the wall, and metal work most siding crews will not touch. Extera Works is a two-partner outfit — Vlad and Dzmitry, who work on site with their crew — based on Cape Cod and covering the Cape and the South Shore. Its site is plain about the scope: exterior installation and custom copper, meaning gutters, flashing and copper pans. Cedar is the bulk of it. Natural white cedar shingles, painted white cedar, Alaskan yellow cedar, CBS double-coat shingles, fiber cement on a new build. Pool houses on summer properties, the exterior of a new build, a single gable and its rotten trim replaced in a tight space with a white fence right in the way, a rental house finished before summer arrived. Customers keep pointing at the same small things: the corners, the trim details around a garage and a front entry, the lines staying straight a year on. Copper is the other half. In February, half-round seamless copper profiles on a Cape-style house and copper gutters finishing a painted white cedar job; this spring, zinc-coated copper gutters on a new pool house; in June, a roof replaced with copper fabrication. Two things to know before calling. The written history is brand new — all 23 reviews on file were posted in 2026, every one of them five-star. And this is a specialist rather than a general contractor: siding, trim, windows and copper are the job list, so a wider renovation means lining up the other trades yourself. One customer with an addition said the tie-in to the existing house was the part they were most nervous about, and it turned out to be the part that came out best. For a cedar-shingle or fiber-cement exterior on the Cape or the South Shore — especially one where copper gutters, flashing or a fabricated cap belongs in the picture — this is a narrow, owner-run crew that does exactly that work. Ask for the shingle grade and the copper details to be written into the quote, since both move the price.
