The coastal weather in the Pacific Northwest is really quite a special challenge for any Bellingham roofer who is charged with keeping the buildings firm and safe. As average annual rainfall is more than 36 inches and there is consistent maritime humidity, the residential and commercial properties in the region are very often exposed to the deterioration caused by moisture. This kind of situation calls for deep expertise in moisture control to stay away from such problems as moss being deposited, wood decay, and the wearing down of the shingles locally.

A certified Bellingham roofer usually opts for top, tier materials that are able to last even when exposed to very humid conditions. Commonly chosen for their harmony between price and capacity to stand up to the wind are asphalt shingles with algae, resistant granules and those of architectural grade durability. However, metal roofing has been the favorite in terms of longevity and robustness because of its strength to deal with heavy rain and snow effectively and at the same time, it is very resistant to the kind of corrosion that is typical of the salt, air environments near the bay.

Besides the choice of materials, the importance of proper ventilation and drainage systems cannot be overemphasized. Local folks highlight how vitally important it is to keep gutters in line and have proper flashing in place so as to be able to repel rain which has been blown by the wind and also prevent the formation of ice dams during the winter freeze, thaw cycles. The weather, specific installation techniques are a great way for the owners to make sure their roofs can stand the peculiar atmospheric pressures of the Bellingham area.
