Are you considering pine trim or fascia for your roof but worried it might rot in Seattle’s constant rain? Does the lower cost of pine sound appealing, but you’re concerned it could lead to bigger problems (and expenses) down the road?
At RoofSmart, we’ve worked on hundreds of Seattle-area homes where pine looked great at first but started rotting, leaking, or falling apart within just a few years. And when that happens, it’s rarely just the trim that needs replacing.
Since pine wood is such a popular option in the Seattle area, we wanted to give you an honest review of how it performs based on what we’ve seen (and had to repair) on our customers’ roofs over the years.
In this article, we’ll walk you through the pros and cons of pine wood for roofing trim, how it holds up in our climate, and when it makes sense (or doesn’t) for your specific needs.
We’ll also cover long-term costs, real-life damage examples, and how to decide between pine and more durable alternatives like cedar.
What are the benefits of using pine wood on your roof?
Pine wood is a popular choice for homeowners and contractors everywhere because of its many benefits:
- Affordability: Pine wood is much cheaper than the alternative option (cedar), which is the biggest reason why it is used so frequently across the country. This also makes it an appealing choice for Seattle area homeowners because roofing costs here are already so high.
- Wide range of uses: Pine can be used for pretty much anything. Often, we see it used as window trim or as a fascia board. It is known for its versatility.
- Strength: Although pine is a lightweight softwood, it is still strong enough to be used as framing or decking.
- Aesthetic appeal: Pine’s natural grain already looks good, making it a good option for use on the outside of your home. Plus, it can easily be stained or painted to match your home’s color scheme.
What problems can pine wood cause on your Seattle home?
Although pine has many great benefits, it is important to consider the potential drawbacks that it has.
At RoofSmart, we visit at least one home every week in the Seattle area where pine was used as window trim or a fascia board and has completely rotted after about three years.
Here’s an example of some pretty bad rot from a recent customer:
Because pine is a softwood, it is more likely to rot and be damaged by water than hardwood.
Here are some factors that impact how likely pine is to rot:
- Is it treated or sealed? Untreated pine usually only lasts 3 to 10 years outside before it rots and must be replaced. We typically see pine used on the outside of the house rotting in just a few years. If it’s sealed or treated, it might last a little longer.
- What’s the climate like? If you live in the Seattle area, then you’re out of luck when it comes to using pine on the outside of your home. The Seattle climate is very humid, and it rains a lot for most of the year. Pine wood is eventually going to rot with all of that exposure to moisture because softwoods soak up water easily.
Most homeowners choose pine wood because it is cheaper. However, because it is very susceptible to leaking in the Seattle rain and humidity, you might end up having to replace your pine fascia boards or trim after only a few years.
In the long run, this will cost you more money. Plus, if the pine is left to rot for too long, the water damage and rot can begin to spread to the surrounding wood, causing a much bigger and more expensive problem.
When is pine wood a good option for my home?
If you’re looking to stick to a strict budget for your roofing project, then pine is probably the best option for your fascia and trim boards. Affordability is the biggest reason why homeowners choose pine. It performs well for the price it’s set at, until it has to face moisture.
It’s also a good option if you’re looking for a quick, cheap fix because you’re moving. You probably don’t want to spend a ton of money on a house that you’re not going to live in.
If you do choose pine, make sure that it’s treated, or at least sealed. This will help protect it from moisture.
If you trust your roofing contractor to do a good job installing your roof so that there are no leaks around the fascia board or areas with trim, then you’ll probably be good with pine.
How do I know if pine wood is not the right fit for my home?
If you live in a rainy, humid area like Seattle, then pine is not a good option for you, even if it’s treated (however, it’s ultimately your decision what goes on your house, no matter what your roofer recommends).
If you’re looking for the longest-lasting and most durable material for fascia or trim board, then pine is not a good fit. Instead, we recommend choosing cedar because it is more resistant to water damage and will hold out longer in the rainy, damp Seattle weather.
If you’re looking for a wood option that has good long-term value, then pine might not be a good fit for your Seattle home. Sure, pine is about 3 times cheaper than cedar. But what about when it rots after a few years and you have to pay your roofer to come back and fix it?
And what if the water damage has spread to other parts of the roof by then as well? In the long run, it can easily end up costing you the same amount or more than if you had just installed cedar to begin with.
How Can You Be Sure Your Roofing Contractor Is Qualified to Recommend the Right Materials?
Now that you understand the pros and cons of using pine for roof trim, especially in Seattle’s wet, unforgiving climate, it’s clear that choosing the right material is only part of the equation. The other part? Making sure your roofer actually knows what they’re talking about.
Because even the best material won’t last if it’s installed by someone who cuts corners or doesn’t understand what works in your local environment.
