Roofing in Lynden
What north Whatcom weather does to a Lynden roof.
Lynden sits on open, flat ground close to the Canadian border, so roofs here take more wind and cold than homes tucked into the hills around Bellingham.
Lynden homes
From farmhouses to newer neighborhoods.
Older homes and farmhouses around Lynden often have layers of old roofing, cedar underneath, or decking that has been patched over the years. We tear off to the deck, replace what is soft, and give you a clean, watertight roof.
Many newer Lynden neighborhoods are reaching the age where the original builder-grade shingles are wearing out. A GAF system with proper ventilation and new flashing is usually a big step up from what went on the first time.

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.
