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.

Sherman General Contracting LLC installs new roofs for homes across Whatcom County, WA.
Expert Roof installation in Whatcom County, WA
Roof installation in Whatcom County means building for a climate that rarely lets up. The county sits in a marine environment where driving rain arrives sideways off the water, damp air lingers between storms, and a moss season that runs from fall through spring puts near-constant pressure on any roofing system. A roof that handles generic conditions will wear faster here than one built with those local realities in mind. At Sherman General Contracting LLC, we approach every installation with the integrity and craftsmanship that our company was founded on. We inspect the roof deck before anything new goes down, checking for soft spots, rot, or moisture damage that a previous roof may have hidden. Underlayment, flashing, and ventilation all get the attention they need for this specific climate. We serve homeowners across Whatcom County and take pride in building roofs that hold up through what this region actually throws at them. Contact us to get started.

FAQ
Roof installation FAQ
Common questions about roof installation in Whatcom County, WA.
A full replacement is the right call when repairs are no longer keeping up with leaks or when the deck itself has taken on moisture damage. Homes across Whatcom County with aging roofs often have hidden deck issues that only show up once the old roofing is removed.
Moss thrives here because the county's mild temperatures, persistent shade from conifers, and long wet season give it nearly ideal conditions for most of the year. Once established, moss holds moisture against the roofing surface and can lift shingle edges over time.
Rain in Whatcom County frequently arrives sideways, pushed by wind off the water, so flashing and underlayment details matter more here than in drier inland areas. Ventilation planning also needs to account for the sustained dampness that keeps attics from drying out between storms.
Yes, we serve homeowners throughout Whatcom County, WA. Reach out to us to discuss your project and get the process started.
We inspect the deck before any new material goes down, looking for soft spots, delamination, or rot that slow leaks may have caused over time. Any damaged sections get replaced so the new roof has a solid, dry surface to sit on.
Yes, salt-laden air moves well inland from the coast on prevailing westerlies and accelerates corrosion on exposed metal fasteners and flashing components. Accounting for that during installation helps the roof system hold up through Whatcom County's long wet season.
