Siding Contractor Software in Washington

Washington's roofing and siding law names siding in its title, so a siding contract here is written to a statute. It is in writing, with a copy to the homeowner at signing. It carries an itemized list of the work, the grade, quality, or brand name of the siding, the price, the contractor's registration number, the salesperson's name and address, and a statement of whether any of the work will be subcontracted. If the homeowner is financing the job, a three-day right to cancel goes in the contract in capital letters, and no work starts until it has run. Any sale made in the home carries three business days to cancel. Before a residential job of $1,000 or more starts, the customer also signs the state's disclosure statement about registration, bonds, and liens, and the contractor keeps it for three years or gives up the right to a lien.

The registration itself is with the Department of Labor and Industries, with a $15,000 bond for a specialty contractor and $30,000 for a general, plus $200,000 in liability coverage and $50,000 in property damage coverage. Working without it costs $1,200 to $10,000 for each day.

Rain is the siding market west of the Cascades. Seattle gets under 40 inches a year and Forks gets more than 100. Water gets behind anything, so the trade here is rainscreen, flashing, and housewrap as much as it is the siding itself. The 2021 residential code has applied in every city and county since March 15, 2024, and the inspector looks at the weather barrier. Cedar is the native material and still the look people want. Fiber cement has most of the replacement market because it takes the wet without rotting, and vinyl is the price option. On June 28, 2021, Sea-Tac hit 108 degrees, and a wall that faces the afternoon sun matters when the material is chosen.

The houses are not old. The median Washington house was built in 1985 and fewer than one in ten date from before 1940. The work is the 1980s and 1990s subdivisions in Kent, Federal Way, Marysville, and Spokane Valley, where the first hardboard and the first vinyl are finished. Wind puts siding on claims. On November 19, 2024, a storm put more than 600,000 homes in the dark, and on December 14, 2006, the Hanukkah Eve storm cut power to 1.5 million people. Washington has no deductible statute of its own. The state added 61,200 people in the year to April 1, 2026, with Seattle, Tacoma, Pasco, Vancouver, and Kennewick at the top of the list.
