If you live in rainy Oregon, you know the importance of a high-quality roof. Your roof keeps rain and wind out while enhancing your home’s appearance. With the high rainfall in the area, any sign that your roof may be aging or failing must be responded to immediately to prevent serious issues like water damage, wood rot, and mold. Many materials are popular for roofs in Oregon, impacting the project cost.
The state average cost range to replace your Oregon roof is $8,000 to $15,000, with most homeowners spending $11,500 for a 2,000 sq.ft. roof replacement using architectural shingles on a cross-gable roof. This project’s low cost is $3,750 for basic 3-tab asphalt shingles installed on a 1,500 sq.ft. gable roof. The high cost is $54,000 for a 3,000 sq.ft. roof replacement using a composite tile that looks like cedar shakes on a cross-gable roof.

Homes in Oregon range from below average to well above, meaning your roof size varies. Many popular roof shapes in Oregon are also more complex or larger than average, requiring more covering material.
The total cost range per square foot for a roof replacement in Oregon is $2.50 to $43 per sq.ft., depending on the material, with basic 3-tab shingles 1 being the least costly and reclaimed slate 2 tiles costing the most. Many homeowners pay around $5 to $8 per sq.ft. for their new roofs. Below are the average costs of a roof replacement in Oregon based on the roof size and the national average costs for the same size.
|Roof Size||Replacement Cost (Oregon)||Replacement Cost (National Average)|
|1,000 sq.ft.||$2,500 - $43,000||$4,750 - $10,000|
|1,200 sq.ft.||$3,000 - $51,600||$5,700 - $12,000|
|1,350 sq.ft.||$3,375 - $58,050||$6,413 - $13,500|
|1,500 sq.ft.||$3,750 - $64,500||$7,125 - $15,000|
|2,000 sq.ft.||$5,000 - $86,000||$9,500 - $20,000|

|4,500 sq.ft.||$11,250 - $193,500||$21,375 - $45,000|
Many roof shapes are popular in Oregon, leading to a range of pitched roofs. The pitch refers to the roof’s angle or how steep it is. With the amount of rain the state sees, most homes have a conventional pitch, but many gambrel and mansard homes with steep slopes 3 are in the area. Steep roofs and complex roofs have higher costs per square foot than conventionally pitched roofs due to the extra work. Flat roofs are less common in Oregon due to the rainfall, but some modern homes feature them. Flat roofs use different materials than other roofs, so they have different costs. You may have a low-slope roof, which may use conventional or flat-roof materials, depending on its style and placement. Below are the average costs of roof replacement in Oregon based on the roof pitch and the national average costs.
|Roof Pitch||Cost per Sq.Ft. (Oregon)||Cost per Sq.Ft. (National Average)|
|Conventional Slope||$2.50 - $43||$4.75 - $10|
|Low Slope||$2.50 - $43||$4 - $10|
|Flat||$3 - $9||$4 - $10|
|Steep Slope||$4 - $35||$8.85 - $15.25|
Many popular materials may be used on roofs in Oregon. Generally, most prefer materials better suited to rain because of the heavy rainfall. This includes asphalt 4 shingles and architectural shingles, particularly algae-resistant architectural shingles. Metal and composite roofs 5 are also popular because both materials come in a range of styles, are long-lasting, and not impacted by moisture. Another popular material for its longevity is slate tiles, with many people opting for reclaimed slate tiles as the more sustainable option. While not as durable, clay tiles and cedar shakes get a fair amount of use. Each material has a cost and installation difficulty, impacting labor costs. Below are the average costs per square foot for installing each material in Oregon and the national average costs.
|Material||Cost per Sq.Ft. (Oregon)||Cost per Sq.Ft. (National Average)|
|Asphalt Shingles||$2.50 - $4||$3 - $15|
|Architectural Shingles||$5 - $10||$6 - $15|
|Metal||$8 - $16||$4.50 - $40|
|Composite||$8 - $18||$7.50 - $13|
|Cedar||$10 - $14||$6 - $18|
|Clay||$10 - $15||$10 - $25|
|Reclaimed Slate||$22 - $43||$15 - $25|
Oregon homes range from traditional to extremely modern and so do the roofs. While gable and hipped roofs are two of the most popular, you can also find many gambrel and mansard roofs and modern homes with butterfly roofs. The more complex the roof, the higher its cost to replace. Gambrels and mansards have much higher costs than other roof types. Cross-gable, Dutch-gable, and hipped roofs require more material than a standard gable roof, even though their costs per square foot are the same. Below are the average costs per square foot for roofs of different shapes in Oregon and the national costs.
|Shape||Cost per Sq.Ft. (Oregon)||Cost per Sq.Ft. (National Average)|
|Gable||$2.50 - $43||$4.75 - $10|
|Hipped||$2.50 - $43||$4.75 - $10|
|Dutch||$2.50 - $43||$4.75 - $10|
|Butterfly||$2.50 - $43||$4.75 - $10|
|Gambrel||$4.50 - $37||$5 - $25|
|Mansard||$7.50 - $37||$11 - $21|
While your Oregon roof may have various shapes or materials, most roof replacements proceed the same. They include a tear-off and new material installation. Most roof replacements can be broken down by cost into the tear-off, material, and final installation. The tear-off is not always required, saving costs on some installations. Below is the average cost breakdown for a roof replacement in Oregon.
|Project Area||Cost per Sq.Ft|
|Tear-Off (Optional)||$1 - $5|
|Material||$0.50 - $20|
|Installation||$1 - $18|
If you have an existing asphalt roof, you may have the option of putting another layer of roofing on top rather than tearing it off. This is called roofing over and is less expensive than a full roof replacement. However, this is not recommended in Oregon, even though it is legal to have up to two roofing layers.
With the heavy rainfall in Oregon, your existing shingles and roof deck may contain moisture, shortening your roof’s lifespan. Moss is a big problem with shingles in Oregon, and moss under a new roof could cause the new roof to deteriorate faster. You may have moisture problems or wood rot on your roof deck that are not seen unless the existing shingles are removed. While a roof over is less costly, a full roof replacement is the recommended route in Oregon for most homes.
If you have a skylight in your roof, a roof replacement is also a good time to replace the skylight. During a skylight replacement, the surrounding roof material must be removed. This makes a skylight replacement faster and easier when done during a full roof replacement. The average cost of skylight replacement is $1,300 to $3,000.
If your home’s deck has suffered moisture damage, sags, or is compromised, you may need to replace it when you replace the roof. The average cost for a 2,000 sq.ft. roof is around $4,300 and $6,600.
This depends on your roof’s material. Asphalt roofs should be replaced every 15 to 20 years, but some materials like slate last much longer.
Most metal roofs last around 50 years in Oregon, but some last longer.
This depends on your roof’s material. Asphalt roofs last 15 to 20 years, newer architectural shingle roofs last up to 50, and slate roofs can last up to 200.
This depends on your roof’s material and complexity. Expect costs of between $1 and $14 per sq.ft.
