Mature trees on large lots
The nineteenth-century plan gave every property a large lot, and a century and a half later those lots carry substantial mature trees, frequently close to the houses. That produces the inland problem set in a concentrated form.
- Heavy leaf and needle load in gutters and valleys
- Limbs directly overhanging roof surfaces
- Slopes that stay shaded and damp for long periods
- Moss and algae on north-facing aspects
- Whole-tree risk in severe storms
