We loved working with Sam and having him build this wheelchair ramp! He came in under other bids in time frame and cost. Great communicating when he would be on site and when different materials would be available. Respectful of our home and cleaned up really well at the end of the job. Sherman contracting is our new go-to for any contracting job.

Roof repair in Whatcom County, WA
Sherman General Contracting LLC provides roof repair for homeowners across Whatcom County, WA.
Expert Roof repair in Whatcom County, WA
Roof repair in Whatcom County, WA means working with conditions that most roofing guides never account for. Wind-driven rain off Pacific storm systems pushes water sideways and up under shingle edges, flashing joints, and vent boots that would stay dry in a calmer climate. Moss is a near year-round pressure here. Whatcom County's long wet season keeps shaded and north-facing roof sections damp for extended stretches, giving moss the moisture and time it needs to lift shingle edges, trap debris, and hold water against the roof deck. Left unaddressed, that moisture works into the decking below and turns a small repair into a much larger one. At Sherman General Contracting LLC, we approach every roof repair with the integrity and craftsmanship our company was built on. We look at the full picture — flashing, decking condition, moss coverage, and penetrations — not just the spot where water is showing up inside. We serve homeowners across Whatcom County and the surrounding region. If your roof is showing signs of damage, contact us to get the repair done right.

FAQ
Roof repair FAQ
Common questions about roof repair in Whatcom County, WA.
A targeted repair is often the right call when damage is localized, such as a failed flashing run, a moss-damaged section, or a few storm-lifted shingles. If moisture damage has spread across multiple roof planes or the decking is compromised in several areas, a full replacement conversation makes more sense.
Most leaks in Whatcom County start at transitions and penetrations — flashing, vent boots, chimneys, and valleys — rather than in the open field of shingles. Wind-driven rain pushes water sideways and upward into gaps that would never leak under a straight-down rain.
Moss causes real structural damage over time in Whatcom County. It lifts shingle edges, holds moisture against the roof deck, and traps debris that accelerates material breakdown well before a roof reaches the end of its expected life.
Yes, we serve homeowners throughout Whatcom County, WA, as well as Skagit County, Snohomish County, and San Juan County. Contact us to discuss your repair needs regardless of where in the county you are located.
The combination of driving rain, persistent moisture, and a long moss season can cause localized issues — like a lifted shingle or a failing seal around a vent — well before a roof reaches the end of its expected life. Whatcom County's climate is genuinely harder on roofing systems than drier inland areas.
A post-storm inspection is a practical step even without visible leaks, since wind can lift shingle tabs or separate flashing edges in ways that are not obvious from the ground. Catching those issues before the next storm prevents a minor fix from becoming a major repair.
