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.

Fraser Valley outflow windsIn winter, cold northeast winds pour out of the Fraser Valley across north Whatcom County. Shingles need the full nailing pattern and sealed edges to stay put.
Freeze and thawCold snaps after long rainy stretches let water freeze in gutters and at the eaves. Ice and water leak barrier at the edges keeps that water out of the house.
Rain and mossLong wet seasons grow moss on north-facing slopes and shaded roofs. Moss lifts shingle edges and holds water against the roof.

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.

Shingle roof replacement by Topside Roofing & Siding

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.
