Florence occupies a unique position on the Oregon Coast where the Siuslaw River estuary creates a microclimate all its own. The town sits in Lane County just south of the Siuslaw National Forest, surrounded by sand dunes that channel wind off the Pacific directly into residential neighborhoods along the harbor, Old Town, and the Rhododendron Drive corridor.
Annual rainfall in Florence averages around 65 to 70 inches, with the heaviest months running from November through March. Winter storms regularly push sustained winds above 40 mph, and gusts of 60 to 80 mph are not uncommon during Pineapple Express events. The salt-laden air from Heceta Head and the open coastline corrodes metal flashing, degrades shingle adhesive strips, and accelerates moss and lichen colonization on north-facing roof planes.
Homes in the Florentine Estates, Greentrees, and Sandpines neighborhoods face particular exposure to wind-driven rain due to the flat terrain and proximity to the dunes. Properties along Bay Street and the harbor are subject to additional salt spray from the river mouth. Meanwhile, homes tucked into the forest canopy along North Fork Siuslaw Road contend with persistent shade that promotes moss growth and debris accumulation in gutters and valleys.
Tru-North crews travel south from Newport via Highway 101, roughly a one-hour drive along the coast. We know this stretch of the Oregon Coast intimately and spec materials rated for the exposure conditions Florence roofs actually face — not what a generic contractor from Eugene would assume.
