Home › Recent Projects › Roof Replacement in Bothell, WA (Landmark PRO, New Skylight, Barge Boards)
Squatch Roofing replaced the roof on a two-story home in Bothell, WA 98021 in August 2026 with CertainTeed Landmark PRO shingles and brown metal flashing. The job added a new 2×3 skylight, re-flashed the skylights into the new roof, replaced damaged decking, and replaced the barge boards along the rakes at no charge after the crew found rot at a rake end. The July 15 inspection documented worn shingles and weathered ridge caps with exposed nail heads. The crew was on site August 26 to 28, and a follow-up check on September 1 covered the roof and the attic.

What Squatch Found on the Inspection
The inspection on July 15, 2026 started in the attic and then put a drone over the roof.
- Ridge and hip caps: the cap shingles were weathered, with nail heads sitting exposed on top of the caps and dark wear along their edges.
- Shingle surface: up close, the laminate shingles showed dark patches where the granule surface had thinned.
- Vents: plastic box vents spread across several slopes.
- Skylights: the drone photos show skylights in the roof, framed by flashing that would have to come out with the old shingles.
- Attic: the inspector photographed the underside of the OSB deck and the framing from inside.
What We Recommended
Squatch recommended a full tear-off and a CertainTeed Landmark PRO roof with brown flashing, and the homeowner approved it. Because the skylights sit in the field of the roof, the scope included re-flashing them into the new shingles, and it added one new 2×3 skylight. The decking line covered wood found damaged once the old roof came off. The barge boards along the rakes were added to the job at no charge.
What We Installed
- Shingle: CertainTeed Landmark PRO with matching ridge cap. The job file records the color as espresso; the photos show a dark shingle.
- Flashing: brown metal flashing at the skylights, pipe flashings, and vents, as written on the job.
- Underlayment: CertainTeed RoofRunner synthetic underlayment over the full deck, with a black membrane run up the valleys and along the walls first.
- Decking: new plywood cut into the OSB deck where sheets were replaced, and new OSB over the trusses on the section that came off entirely.
- Skylights: a new 2×3 black-frame fixed skylight, and the skylights re-flashed into the new roof.
- Trim: new barge boards along the rakes.
- Ventilation: a ridge vent under the ridge cap, with box vents on the slopes.

How the Project Went, Day by Day
August 26: the crew tarped the planting beds, set plywood against the house where the dump trailer parked, hung a screen across the front of the house, held a safety meeting, and started the tear-off. Under the old shingles was an OSB deck. Several spots got new plywood, cut in around a hip and along the slopes, and one OSB sheet was dark-stained. By evening the black membrane was in the valleys and along the walls, new pipe flashing was set, and RoofRunner covered the roof.
August 27: shingling started at the eaves and worked up the slopes. The crew photographed the skylight frames as the new courses reached them. By evening most of the slopes were shingled.
August 28: when the old roofing was pulled back at one rake, the end of the barge board was rotted through. The crew also opened one roof section down to the trusses and re-sheathed it with new OSB, cutting openings for the vents. The new skylight arrived in its box, a black-frame fixed unit. The completion photos that evening show the finished slopes, the skylights in brown flashing, and new barge boards on the rakes.
September 1: a follow-up check. In the attic, a line of daylight runs along the peak where the ridge vent opening is cut. On the roof, shingle edges were lifted at the pipe flashings, the vent flashings, and the skylight flashing to photograph the flashing and sealant underneath, and the ridge vent was photographed under the cap.
The Finished Roof
The house now carries Landmark PRO over RoofRunner, with brown flashing at the skylights and penetrations, a new 2×3 skylight, a ridge vent under the cap, and new barge boards along the rakes. The new boards went up unpainted in the completion photos.
What This Roof Replacement Cost
Project investment range: $27,200 to $42,700. This range reflects the scope of this completed project and is not a current quote. It is anchored on the final invoice total, which includes Washington sales tax.
Three things shaped this price beyond the shingles: the skylight work (a new 2×3 unit plus re-flashing the existing skylights), the decking replaced after tear-off, and a roof broken up by hips, valleys, and walls that each needed flashing. The barge board replacement was done at no charge, so it did not add to the total.
What Homeowners With Similar Roofs Should Know
Skylights get flashed with the roof. On this house, re-flashing the skylights into the new shingles was its own line on the job. If you have skylights, ask whether re-flashing is in the quote.
Rake trim can hide rot. The barge board rot was not visible from the drone photos. It showed up when the roofing at the rake was pulled back on day three.
Decking is decided on tear-off day. Most of this deck stayed, with new plywood cut in where needed, but one section came off down to the trusses. The file records a decking line, not a sheet count.
