Are you trying to decide between 30-year and 50-year shingles, but you’re unsure if the higher cost is actually worth it? Do you feel frustrated by how hard it is to get a straight answer about what these shingles really cost (and how long they last) in Seattle’s wet climate?
At RoofSmart, we understand that choosing a roof can be overwhelming and difficult. That’s why we recommend roofing options to each individual customer based on their needs, preferences, and budget. We help hundreds of customers each year weigh their options and find the best roof for their home.

You’ll also learn which hidden factors impact your final roofing bill, and how to decide which option is right for your budget and long-term goals.
For an average-sized roof in the Seattle area (around 2,000 square feet), it costs about $30,000 (around $10 to $15 per square foot) to install standard 30-year asphalt shingles. This price includes the cost of materials and labor to install it.
Note: the square footage of your home is not a good way to approximate your roof size because overhangs, unheated space (like a garage or overhangs), or stacked areas (like a 2 or 3-story area) aren’t included in the square footage of your living space. Remember that the size of your roof and the size of your home are different.
30-year shingles are the classic go-to option for most homeowners in the Seattle area (and across the U.S.) because they are the most affordable roofing option.

If you’re looking at just material costs, 50-year shingles cost about 50% more than standard 30-year shingles. But the cost of a roofing project includes more than just the roofing material, so it’s important to account for all the costs.
In terms of total job costs, installing 50-year shingles only costs about 10% to 15% more than 30-year asphalt shingles. So, this means that if the 30-year shingles cost $32,000, then it would cost around $35,000 ($11 to $14 per square foot) to install 50-year shingles.
50-year shingles are a good alternative to standard 30-year shingles because they are stronger and more durable. They’re considered a designer product because they have a more elegant look than the standard shingles.

The total cost of the roofing project can vary depending on many factors. No matter what type of shingle you choose, the labor costs to tear off the old roof, dispose of it, and then install the new roof will all be the same.
One factor to consider that can change the total price of the job is the cost of the other materials you’ll need for your roof.

With all of these items, you have the option to choose cheap, lower-quality options. Or, you can invest in longer-lasting options that are of better quality.
It can be tempting to choose cheaper options to help keep costs down, but remember that the higher quality options will last longer and do a better job of preventing leaks. This can help you avoid spending extra money on repairs later down the road.
Now that you understand the differences in cost and performance between 30-year and 50-year shingles, you're better equipped to choose the right roofing material for your home and budget.
