Irongate is not a typical Bellingham neighborhood. The area off Hannegan Road and Bakerview is a working district of shops, warehouses, contractor yards, and a scattering of homes on its edges, which means the roofs here range from steep-pitch composition on residences to big low-slope membranes over commercial bays. Alpine Exteriors handles both, and after 25 years of roofing in Whatcom County we know exactly what this corner of town asks of a roof.
Wind Off the Fraser Valley Hits Irongate First
When cold northeast outflow pours down the Fraser Valley in winter, the flat, open ground around Hannegan and East Bakerview gives it a clear run. Those windstorms peel poorly nailed shingles, lift membrane edges, and drive rain sideways into any flashing detail that was done casually. We build for it: six-nail shingle patterns, upgraded starter and ridge products, and mechanically fastened perimeter details on low-slope work rather than relying on adhesive alone.
The other local enemy is ponding. Many of the district's older commercial roofs were built nearly dead flat, and decades of settling leave low spots where water sits for weeks in a Bellingham winter. We correct slope with tapered insulation during re-roofs instead of just installing new material over an old drainage problem.
