Common questions
How many downspouts does a house need?
It depends on roof area, rainfall, gutter size and valleys. Our estimator uses a planning allowance, while the local professional confirms the final layout.
Where should downspouts discharge?
They should release water away from foundations, entries and erosion-prone areas, subject to local drainage rules and site conditions.
