How much do 30-year shingles cost?
For an average-sized roof in the Seattle area (around 2,000 square feet), it costs about $30,000 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.
What are the benefits of 30-year shingles?
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.
Here are the benefits of standard shingles:
- Lowest cost roof material
- Lasts 15 to 25 years: The life expectancy is a little bit lower in the Seattle area because the rain and constant moisture are hard on shingles.
- Good wind resistance
- Good water and leak resistance (when installed properly): Asphalt shingles will do a good job of protecting your roof from Seattle rain. However, if they’re not installed properly, then this can lead to leaks or premature roof failure.
How much do 50-year shingles cost?
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 to install 50-year shingles.
What are the benefits of 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.
Here are the benefits of standard shingles:
- Much lower cost than other premium roofing materials: Premium materials include metal, Cedar shake, or Euroshield. These items are durable and elevate the look of the roof, but they’re much more expensive than asphalt shingles.
- Lasts 30+ years: Just like 30-year shingles, the 50-year shingles have a lower life expectancy in the Seattle area. They’re expected to last 30 to 40 years.
- Thicker and more durable: 50-year shingles have a lot more asphalt than standard shingles. It takes longer for them to wear out.
- Good water and leak resistance (when installed properly): Asphalt shingles will do a good job of protecting your roof from Seattle rain. However, if they’re not installed properly, then this can lead to leaks or premature roof failure. This is the same for any kind of asphalt shingle, no matter if it’s a 30-year or 50-year shingle.
- Elevated design increases curb appeal: 50-year shingles are considered a designer shingle. They have a different lay pattern than 30-year shingles, so they have an elevated feel to them.
What are the cons of 30 and 50-year shingles?
Asphalt shingles are a great option if you’re looking for good coverage on your roof at an affordable price. However, there are some disadvantages to choosing asphalt shingles.
- Low impact resistance: If something falls on or hits the shingles, they can scuff or dent. 50-year shingles are a bit more durable, but it can still happen to them.
- Algae and moss growth: Constant moisture on the roof can lead to the growth of algae and moss. This looks bad and can cause the shingles to deteriorate faster. Moss can even destroy shingles if it gets bad enough.
- You need to clean off debris: If leaves or pine needles get wet and sit on the roof for too long, then they’ll trap in moisture on the shingles and cause them to deteriorate faster. This can lead to leaks and ultimately means you’ll need to repair or replace your roof sooner. This is a major issue for homeowners who live in the Seattle area.
What are the factors that impact the cost of the roofing job?
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.
For example, you’ll also need
- Hip and ridge cap
- Flashing
- Underlayment
- Vents
- Pipe flashing
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.
