Architectural (dimensional) asphalt shingles are the value roof in Bellingham: a 25 to 50 year product life and algae-resistant options that hold up against our moss.
Architectural asphalt shingles are the most common roof we install in Bellingham, and for good reason: they are the best balance of cost and life for our climate. The right line carries a 25 to 50 year product rating, and algae-resistant versions stand up to the moss and the constant damp on north-facing and shaded slopes far better than old 3-tab roofs.
The shingle is only half the job. We install over a proper synthetic underlayment with ice-and-water at the eaves and valleys, not just felt and hope. We fix the ventilation so the deck does not sweat and rot from the inside, and we flash every penetration properly. Done that way, an asphalt roof here lasts the way it is supposed to.

Frequently asked questions.
How much does an asphalt shingle roof cost in Bellingham?
A new architectural asphalt shingle roof on a typical Bellingham home runs $9,500 to $22,000 in 2026. The range depends on roof size and pitch, the shingle line you pick, how many old layers come off, and any decking or ventilation work. We quote it line by line after we inspect.
How long do asphalt shingles last in Bellingham?
Architectural asphalt shingles here generally last 25 to 35 years, sometimes longer with algae-resistant lines and good ventilation. Moss and heavy shade shorten that, which is why we treat ventilation and moss as part of the job rather than an afterthought.
What shingle brands do you install?
We install lines we trust for this climate, including GAF, Owens Corning, CertainTeed, and Malarkey, in algae-resistant architectural styles. We will only spec a product we actually install and stand behind, and we put the exact line in your written quote.
