Slate restoration, copper valleys and a rebuilt eaves detail.

A 1920s stone-and-shingle house where the field of the slate was sound and everything around it had failed — valleys, step flashing, the eaves return and eighty feet of fascia behind the gutters. The honest scope was a restoration, not a re-roof, and it cost roughly a third of what a replacement would have.

Scope

Selective slate replacement in matched stock, new copper valleys and step flashing, fascia and soffit rebuild, half-round copper gutters and leaders.

Why it mattered

Two previous contractors had quoted full replacement. The field slate had another forty years in it.

A closer look

Homes in this county are worth doing properly

Steep slate and cedar, deep valleys, chimneys in inconvenient places, and trim details that a stock product will never match. That is the housing stock we work in, and it is why we specify to the house.

Every job, not just the photographed ones

What every client gets.

Most of our work is unglamorous and never photographed — a chimney reflashed, a rotten sill spliced, a downspout repiped to daylight. It runs the same way.

How we run a job

A written scope

Named materials, stated quantities, listed exclusions and photographs attached — so a second quote is a real comparison.

Photographs of what we find

Before it is covered up, whether or not it changes the price. You keep them.

One project manager

Reachable directly for the whole job, not a call center and a scheduling app.

Registered warranties

Manufacturer registration filed for you at close-out, with the confirmation sent on.
