Cedar shakes and asphalt shingles compared for a wet Northwest climate: looks, upkeep, moss, fire safety and cost, so you can pick the right roof.
Two classic Northwest roofs
Walk through older Seattle neighborhoods and you will see plenty of cedar roofs next to asphalt shingles. Both can work well here. They just ask different things of you, especially in a climate with this much rain, shade and moss.
Here is how they compare on the things that matter most to Puget Sound homeowners.
Looks
Cedar has a natural, textured look that weathers to a silver-gray over time. It suits Craftsman, cabin and older Northwest homes. Shakes are split and thicker, with a rough surface. Cedar shingles are sawn, thinner and more uniform.
Asphalt shingles come in many colors and styles. Architectural (dimensional) shingles have a layered look that can echo the shadow lines of wood at a lower cost.
Upkeep in a wet climate
This is the biggest difference. Cedar needs regular care in the Northwest: cleaning off needles and debris, treating moss, replacing split or cupped shakes and making sure the roof can dry out between storms. A shaded cedar roof that stays wet can rot and wear out early.
Asphalt shingles need less attention, but they are not maintenance-free. Moss still grows on them in shady spots, and gutters still clog. Our guide to roof moss removal covers both.
Fire safety
Untreated cedar burns more easily than asphalt shingles, which commonly carry a Class A fire rating. Fire-retardant-treated cedar is available and can reach higher fire ratings when installed as a tested system. If you live near woods or open land, ask about fire ratings, and check local codes and HOA rules before choosing cedar.
Cost and lifespan
Cedar usually costs more to buy and install than asphalt, and its long-term cost depends on how well it is maintained. A well-kept cedar roof in a sunny spot can last a long time. A neglected one in deep shade may not.
Asphalt costs less up front and is easy to repair and replace. For a ballpark on your home, try our roof cost calculator.
What about metal?
Standing-seam metal is worth a look if you want something long-lasting. It sheds rain quickly, gives moss little to hold on to and handles wind well when it is installed right. It costs more up front than asphalt, and some HOAs limit it, so ask first.
How to choose
- Choose cedar if you love the look, your roof gets decent sun and you are ready for regular upkeep.
- Choose asphalt if you want a lower price, easy repairs and less maintenance.
- Consider metal if you plan to stay a long time and want the least upkeep.
Whatever you choose, installation quality counts as much as the material: good underlayment, flashing and ventilation are what keep water out in a Northwest winter.
