Roof Replacement Cost Factors

Many things go into the cost of a new roof, including roof size, roofing material, additional services, labor costs and more. We break down some of the most common cost factors so you can budget accurately for this project.

Roof Size

Unsurprisingly, roof size is one of the most important factors when it comes to determining roof replacement costs. The average roof size in Seattle is around 1,800 square feet—keep in mind that your home’s square footage isn’t the only thing contributing to roof size. Pitch, slope, eave width, and roofing over garages and porches can all affect roof size.

Size (Sq. Ft.)Average Cost
1,000$3,450–$11,100
1,500$5,200–$16,650
2,000$6,900–$22,200
2,500$8,650–$27,750
3,000$10,350–$33,300

Roof Material

The type of roofing material your roof is made of will also affect the cost. Metal and slate roofs are well-suited for Seattle’s rainy climate, but they’re among the pricier options for roofing materials. Materials like asphalt shingles, rubber, and wood shingles won’t break the bank, but they’re more prone to water-related damage and may not last as long.

MaterialAverage Cost per Sq. Ft.
Asphalt shingle$3–$11
Metal$5–$22
Slate$10–$30
Rubber$3–$13
Wood shingle$6–$18

Roof Complexity

The type of roof also matters. More complex roof styles like hip roofs and Dutch gable roofs will use more material and take longer to install than simple roof styles like classic gable roofs and flat roofs. If your roof has architectural features like dormers, towers, or gables, installation will be more difficult and more expensive.

Roof Removal

Before installing a new roof, you’ll need to remove and dispose of old roofing materials. Roof removal costs an average of $1 to $5 per square foot and is usually included in your roofing quote. 

After your roofer removes the old roof, they’ll assess the underlying parts of the roof to confirm everything is in good condition and able to support the new roof. In some cases, you may need to repair or replace parts of the underlying roofing structure, like the sheathing, which can add $2 to $7 per square foot to the total project cost.

Warranties

A warranty against manufacturer defects and other roof problems is a good way to protect this major investment. Many installers and manufacturers include a limited warranty in the purchase price, but you can add an extended warranty for $500 to $5,000, depending on the coverage.

Roof Replacement Pro Costs

Hire a local roofer to install your new Seattle roof. Not only can DIY installation lead to water damage and potential structural issues, but it may void any warranties and put your homeowners insurance coverage in jeopardy. 

Roofer Costs

Labor costs for a Seattle roofing pro will make up about 40% to 60% of your total project cost. When hiring a roofer, be sure the quote has a detailed breakdown of all costs, any common roofing terms you don’t understand are clearly explained, and you know when payments are due and how much they’ll be.

Permits and Fees

You don’t need a permit to replace your roof in Seattle for a one- or two-family home unless you’re making structural changes or replacing your roof sheathing. Surrounding King County cities may have different permit regulations, though, so confirm the requirements and ensure you have the appropriate permits and have paid any necessary fees before starting work. 

Pro Tip

A good indicator that the roof needs to be replaced and done by a professional is evidence of missing shingles or other materials. If the roof is beginning to lose shingles during major storms, then it is likely time to have it replaced rather than making repairs.

Does Roof Replacement Increase Home Value?

A new roof can add significant value to your Seattle home, offering a 50% to 60% return on investment (ROI). How much your home’s value will be affected depends on the roofing material, expected lifespan, and more. When it comes time to sell your home, having a new roof can be a big draw for potential buyers—knowing roof replacement costs won’t crop up in the near future can put buyers’ minds at ease.
