Here is the short version. Asphalt shingle wins on up-front cost and is the right pick for most Whatcom County homes. Metal wins on lifespan and on shedding moss and water, and it makes the most sense if you plan to stay put for decades or you have a low-slope or hard-to-reach roof. Both are good roofs when they are installed right for our climate. The choice comes down to how long you will own the house and how much you want to spend now versus later.
Let me lay out the real differences so you can see where your home lands instead of going off a sales pitch.
Cost, side by side.
This is the first thing everyone asks, so here are the 2026 Whatcom County ranges for a full tear-off and replacement on a typical home.
| Roof type | 2026 range, typical home | Rated lifespan |
|---|---|---|
| Architectural asphalt shingle | $9,500 to $22,000 | 20 to 30 years |
| Standing-seam metal | $18,000 to $45,000 | 40 to 60 years |
Metal costs roughly two to three times more up front. That is real money. But spread it over the life of the roof and the math gets closer. If an asphalt roof lasts 25 years and a metal roof lasts 50, you would buy two asphalt roofs in the time one metal roof serves you. Metal still tends to cost more over the long run, but the gap is smaller than the sticker price suggests, and you skip the disruption of a second tear-off.
Lifespan in our climate.
Rated lifespan is one thing. Lifespan in Bellingham's 35 inches of rain a year and long wet seasons is what actually matters. Asphalt shingle does well here when it is installed with proper ventilation and good flashing, and a quality architectural shingle from GAF, Owens Corning, CertainTeed, or Malarkey will give you its full rated life if you keep moss off it. The thing that shortens asphalt life here is moss, which we cover in why roof moss kills roofs early.
Metal shrugs off our weather better than anything. Water sheets off a standing-seam roof fast, moss struggles to get a grip on smooth metal, and there are no granules to wash away. On the shaded north slopes all over South Hill and the tree-covered lots in Sudden Valley, that moss resistance is a genuine advantage. Metal is also the better answer on low-slope sections where water moves slow.
Noise, looks, and the things people worry about.
Is metal loud in the rain?
This is the number one worry, and it is mostly a myth for modern roofs. A standing-seam metal roof installed over solid decking and underlayment is not much louder than asphalt inside the house. The drumming people remember is from bare metal over open framing on an old barn, not a properly built home roof.
What about looks?
Asphalt shingle looks like a normal roof, which is what most Bellingham neighborhoods expect, and it comes in plenty of colors. Metal has a cleaner, more modern line that suits some homes beautifully and looks out of place on others. On a historic Victorian in Fairhaven, a standing-seam roof can be a striking fit or a clash depending on the home. We will tell you straight which way it leans for your house.
Hail, wind, and fire
Metal handles wind-driven rain and the occasional windstorm very well, and it will not catch a stray ember. Asphalt is no slouch on wind when it is nailed correctly, but heavy hail can bruise it. We do not get a lot of hail here, so that is a minor factor in Whatcom County compared to the rain.
The best roof is not the most expensive material. It is the right material for your home and how long you will own it, installed correctly for our rain. A perfectly installed asphalt roof beats a sloppy metal one every day of the week.
So which wins for you?
Choose asphalt shingle if you want the lower up-front cost, you might move in the next 10 to 15 years, or you want the classic neighborhood look. It is the right call for the majority of homes we re-roof, and our asphalt shingle roofing page walks through how we install it for our climate.
Choose metal if this is your forever home, you want the longest life with the least moss trouble, you have a low-slope roof, or you just love the look and the do-it-once approach. Our metal roofing page covers standing-seam and what it takes to do it right here.
