Around Snohomish County right now, most full asphalt roof replacements land between $14,000 and $28,000, which works out to roughly $450 to $700 per roofing square installed. A square is 100 square feet of roof. Steep, cut-up roofs and hidden rot push past that. Those are market ranges, not a bid. Here is what actually sets your number.
How much do size and pitch matter?
A roof is priced by the area, but a steep pitch and a lot of valleys, dormers, and hips add labor and flashing. A simple gable roof is quick. A cut-up roof with lots of angles takes longer and needs more detail work to stay watertight.
What does tear-off add to the cost?
Roofing over the old layer is cheaper on paper and a mistake here, because it hides rot and voids most warranties. A proper tear-off to the deck can turn up soft sheathing from years of wet winters, which we price up front so the number doesn't jump mid-job.
How much does the material change the price?
Architectural shingle lasts decades and costs less. Cedar shake and metal cost more and each asks for its own detailing. The pick changes the price and the lifespan, so we walk you through what fits the house and the weather it takes.
Where should a roof quote never cut?
The cheap bid reuses old flashing and shoots nails high. New flashing in every valley and around every vent is what keeps the next wet winter out. It's a small line on the quote and the reason a roof stays dry, so it's not the place to cut.
Common questions
The ranges above are the market. We measure the pitch, count the valleys, and look for soft decking before writing anything, so the number you get is built from your roof, not a county average. The walkthrough is free.
