Roofing in Bellingham
What Bellingham weather does to a roof.
Bellingham roofs see long wet winters, wind coming in off the bay and shade from big trees in many neighborhoods.
Bellingham homes
From historic homes to newer neighborhoods.
Older homes in Sehome, the Lettered Streets and Columbia often have past roof layers, cedar boards underneath or patched decking. We tear off to the deck, replace anything soft and install a complete GAF roofing system.
In newer areas like Cordata, Barkley and King Mountain, we see first-generation roofs reaching the end of their life. We check ventilation and flashing so the new roof lasts.

What's included
Every Topside roof replacement includes:
Full tear-off to the deck
No roofing over old roofing. We remove everything so the deck can be checked.
Decking repair
Soft or rotted plywood is replaced before the new roof goes on.
Underlayment and leak barrier
Synthetic underlayment, plus ice and water leak barrier in valleys and at eaves.
New flashing
Walls, chimneys, skylights and vents get new flashing, not reused metal.
Ventilation check
Ridge and intake venting sized so the attic can dry out in our damp months.
Cleanup and walkthrough
Magnet sweep for nails, all debris hauled away, and a final review with you.

Bellingham roofing questions
Do you serve all of Bellingham?
Yes. Topside is based in Bellingham and works in every neighborhood, from Fairhaven and Edgemoor to Cordata, Barkley and King Mountain.
Do you do roof repairs too, or only replacements?
Both. If the roof is in good shape and the problem is in one area, a repair may be all you need. See our roof repair page.
How much does a new roof cost in Bellingham?
It depends on roof size, pitch, layers, material and what we find under the old roof. We give a free written estimate, and monthly payments are available through our financing partners.
What about moss on my roof?
Moss holds water against the shingles and lifts their edges. We can clean and treat a roof that still has life left, or talk through replacement if the shingles are worn out. See roof maintenance.
Is Topside local?
Yes. Topside is a family-owned roofing company based in Bellingham that has been roofing Northwest Washington since 1989.
