If you live in Seattle or the surrounding area, you know that we live in a pretty unique climate.
Here are the top five things about our environment that impact roofs:
1.) The humidity: Humidity in the Seattle area drives up the dew point, making moisture collecting on your roof a more prevalent issue. This can also impact how easily condensation forms inside your attic during the cooler fall and winter months. Moisture build-up in the attic can lead to rotting wood and mold.

2.) Lots of rainfall throughout the year: If you have an asphalt shingle roof, then it is suffering in the rain. If it stays wet for long periods of time, then it can start to deteriorate faster than normal. Even roofs that are more water-resistant, like steel standing seam roofs, can potentially grow algae if it's consistently damp. Some roofs handle water better than others, but a lot of them are impacted in one way or another due to the large quantities of rain that we get here in the Seattle area.
3.) Proximity to the ocean: The salty ocean air is hard on your roofing materials and can cause them to deteriorate faster than usual. You especially have to be cautious when installing a metal roof near the ocean because some types are naturally prone to rusting in ocean air.
4.) Windstorms in the fall and winter: In Seattle and the surrounding areas, it is common to get windstorms with severe gusts during the rainy season. These storms can tear shingles off the roof, and even cause trees or branches to fall on your roof. This level of damage can become a huge headache, especially if your insurance company needs to get involved.
5.) Excessive debris falling from trees: Leaves, pine needles, sap, and other debris can easily shed onto your roof if you have trees on your property or hanging over your roof. Pine needles can fall off at any time of the year, so you have to worry about debris collecting at all times. This debris sits on the roof and gets wet when it rains. Then, it retains that moisture and prevents the roof from drying, which can lead to premature failure, granule loss, and leaks.
For many homeowners in Seattle and the surrounding areas, asphalt shingles are the default because they are the most affordable option.
If cost is your biggest deciding factor, then you'll probably gravitate toward asphalt shingles. As long as you hire a quality roofer, your asphalt shingles should provide great protection for your roof.
Typically, asphalt shingles last 15-25 years in Seattle's climate. Buying thicker shingles and keeping up with regular maintenance can help your roof to last longer.
There are four main types of shingles:
Asphalt shingles are a good option if you want quality coverage for a good price. In most cases, they are a good fit.
However, they are not recommended if you:
Both scenarios will lead to leaks and extreme rot. We've seen it happen a ton in the last 15 years.
If you have a lot of trees on your property, you'll need to be vigilant about removing debris from your roof. When wet debris (from the rain) sits on the roof, it prevents it from drying out and causes the asphalt shingles to deteriorate faster.
If you're considering a roof replacement in the Seattle area, metal roofing is the second most popular roofing option. It lasts for decades, stands up to harsh weather, and gives homes a distinctive appearance. But it's not the right fit for every home or every homeowner.
The best roofing material depends on your budget, long-term plans, the style of your home, and how much maintenance you're willing to take on. Here's what Seattle-area homeowners should know about metal roofing before deciding if it's the right investment.
One of the biggest reasons homeowners choose metal roofing is its longevity. While asphalt shingles typically require replacement sooner, a properly installed metal roof can protect your home for many decades.
For homeowners planning to stay in their home long-term, that durability can offset the higher upfront investment. Instead of planning for another roof replacement in the future, many homeowners see metal roofing as a "buy it once" solution.
Seattle's climate presents challenges that roofing materials must withstand year after year:
We recommend metal roofs because they shed water efficiently and are naturally resistant to moss growth. Unlike rougher roofing materials, metal's smooth surface doesn't provide an ideal environment for moss to establish itself.
For homeowners living near Puget Sound or the coast, metal can also be an excellent choice because many systems offer strong resistance to moisture and corrosion when paired with the appropriate coatings.
Every roof requires inspections and occasional maintenance, but metal roofs generally require less routine upkeep than materials like cedar shake.
Because they resist moss growth and don't absorb moisture like asohalt shingles do, maintenance is much quicker and easier.
Debris won't harm the roof, so you can leave it there without worrying.
The only downside for maintenance is that metal roofs can be very slippery, so proceed with caution when it's wet.
Not all metal roofs look alike. Understanding the differences helps homeowners choose the right appearance for their home.
Standing seam is the premium option and one of the most popular metal roofing systems in the Seattle area.
Its concealed fasteners help protect against water intrusion while creating the clean, modern appearance many homeowners want.
Standing seam is often a great fit for:
You can choose between the following materials:
Steel (most common)
Each one varies in terms of cost, longevity, and corrosion resistance.
Standing seam and aluminum are the least expensive, while copper has the highest cost.
Steel requires special coatings to avoid corrosion, whereas the other materials don't need additional protection.
Exposed fastener systems use visible screws to secure the panels.
While they typically cost less initially, they generally require more maintenance over time because the exposed fasteners can eventually need replacement as washers age and weather.
For many residential homes, standing seam remains the preferred long-term option.
If you've started researching metal roofing, you've probably heard about 24-gauge and 26-gauge steel.
While both are used in residential roofing, thicker steel (24-gauge) generally offers greater resistance to denting and oil canning, particularly in areas with heavy tree coverage or weather exposure.
The best choice depends on your home's needs, budget, and the specific roofing system being installed.
Many homeowners focus on the steel but overlook the finish protecting it.
Metal roofing commonly uses three coating systems:
While each has its place, they differ significantly in color retention, chalk resistance, fade resistance, and long-term appearance.
For homeowners planning to keep their roof for decades, understanding these differences is just as important as selecting the roofing panel itself.
Metal roofing is one of the more expensive residential roofing materials.
However, homeowners should compare more than just installation cost.
When evaluating value, consider:
For homeowners planning to stay in their home for many years, metal roofing often becomes more cost-effective over time than replacing lower-cost materials multiple times.
Despite its advantages, metal roofing isn't ideal for everyone.
It may not be the right fit if:
Like every roofing material, metal involves trade-offs. The key is deciding whether its durability, longevity, and low maintenance justify the higher initial investment.
For many Seattle-area homeowners, cedar offers a classic look that complements any home's architecture. However, it also requires more maintenance than many alternative roofing materials, making it a better fit for some homeowners than others.
The biggest reason homeowners choose cedar is its timeless aesthetic.
Natural cedar creates warmth, texture, and character that manufactured roofing materials often try to replicate. It's especially popular on:
If maintaining an authentic wood appearance is important to you, cedar remains one of the most distinctive roofing options available.
Not all cedar shakes are created equal.
Cedar roofing is available in different grades, each affecting durability, appearance, and price.
Higher-grade cedar products use better portions of the tree with fewer imperfections, providing a more consistent appearance and longer performance.
Choosing the right grade can significantly impact how your roof ages over time.
Seattle's climate is beautiful for trees, but it's also ideal for moss.
Unlike metal roofing, cedar naturally requires more maintenance because moisture and organic debris can encourage moss and algae growth if left unmanaged.
Not to mention that it collects debris (especially small pine needles) pretty easily and that it needs to be retreated every 5 years.
Homeowners considering cedar should expect to do regular maintenance to preserve both appearance and longevity.
For many homeowners, the maintenance is worth it because of cedar's natural beauty.
Cedar is often the right roofing material if you:
If your priority is minimizing maintenance, then you may want to compare cedar with today's synthetic alternatives.
Synthetic roofing is becoming an increasingly popular premium roofing category because it combines the appearance of natural materials with lower maintenance requirements.
For many Seattle homeowners, synthetic shake and slate provide an appealing middle ground between natural cedar and metal roofing.
Many homeowners love cedar, but not the maintenance that comes with it.
Synthetic shake and slate roofing products are designed to mimic the appearance of cedar shake or natural slate for a lower cost and without the maintenance concerns.
For homeowners who want curb appeal with less upkeep, synthetic roofing deserves serious consideration.
RoofSmart compares several leading manufacturers because each offers different strengths.
Among the most common options are:
Each of their synthetic roofing products differ in appearance, material composition, impact resistance, and installation considerations.
Rather than asking which manufacturer is "best," homeowners should determine which product aligns best with their priorities.
Euroshield differs from many other synthetic roofing products because it's manufactured from recycled rubber.
That construction provides characteristics that appeal to homeowners looking for durability while also considering sustainability.
Depending on the product selected, homeowners may also appreciate its ability to absorb impacts differently than more rigid roofing materials.
Synthetic roofing can be an excellent option if you:
Although the upfront investment is significant, many homeowners find the combination of aesthetics and reduced maintenance worth the additional cost.
Concrete and clay tile roofs are known for their distinctive appearance. While they aren't as common as asphalt or metal roofing in the Seattle area due to their high installation cost, they can be an excellent choice for certain homes.
Tile roofing works best when it complements the architecture of the home.
It's commonly found on:
The weight and appearance of tile make it a material that should be selected intentionally rather than simply replacing another roof type.
One reason homeowners invest in tile roofing is its long service life.
However, even though the tiles themselves often last a very long time, individual tiles can crack or become damaged over the years.
Knowing when to repair versus replace becomes an important part of owning a tile roof.

Clay tile resists moisture, insects, and rot, making it a durable roofing material.
For homeowners near the coast, clay tile is a great option for homes exposed to salt air.
However, concrete tile can absorb moisture, making it a prime growth spot for moss and algae. It can also crack if it has absorbed too much moisture and then gets cold.
Concrete tile costs less than clay tile, but it is also less durable.
Because tile roofing is significantly heavier than many other materials, homeowners should understand that switching to tile often involves additional structural considerations.
This is one reason tile replacements frequently make more sense than converting from another roofing material.
Not every roof is steep enough for shingles, shake, or tile.
If your home has a flat or low-slope roof, you'll need a roofing system specifically designed to manage standing water and slower drainage.
Traditional shingles are designed to shed water on moderate to high slopes.
On flat or low-slope roofs, water drains much more slowly, so specialized membrane systems are required to provide long-term waterproof protection.
Several common options include:
Each offers different advantages depending on your home's design, budget, and long-term goals.
For many homeowners replacing a flat roof, one of the biggest decisions is choosing between PVC and torch down.
These systems differ in:
PVC is more durable and handles standing water better than torch down, which is why it's the more expensive option.
For flat roofs, choosing the right insulation can affect both energy performance and long-term roof performance.
Condensation is a huge issue for flat roofs and rooftop decks in the Seattle area that don't get the right type and amount of insulation.
Your flat roof needs a warm roof setup, which layers foam insulation against the rooftop deck to prevent condensation.
Some homeowners love the appearance of metal roofing but have low-slope roof sections.
Metal can be used on low-slope roofs, but not completely flat roofs. Getting your metal roof mechanically seamed gives it the extra leak protection it needs to work on lower slopes.
Homeowners choose metal for their low-slope roof because it has better curb appeal and lasts longer than the other flat roof material options.
