Living under canopy: what Marlborough weather does to roofs
Marlborough roofs live under forest. Oak and pine canopy drops leaves, needles and small branches into valleys and gutters all year, and the debris holds water against the shingles long after a storm has passed. Shaded planes, especially those facing north or toward the lake, stay damp and grow moss that lifts shingle edges over time. The town sits on higher ground than the river towns, so snow lands heavier and lingers, and ice forms at the eaves of houses with uneven attic insulation. The open stretches along Route 2 are the exception: there the wind arrives unbroken and lifts tabs on exposed slopes.
