Task category
Gutters and downspouts
Plan the actual gutter runs and downspout routes around your house. Move from measured footage to quantities, drainage comparisons and clearly scoped costs. Length, slope, fittings, half-round sizing, capacity, installation, cleaning and rain collection. Use the conditions and limitations on each detail page.

Measurement and routes
Gutter lengthAdd measured gutter runs around the house. Gutter sectionsRound a measured run up to stock section length. Gutter slope dropConvert a run and slope into the fall across the gutter. Downspout count by spacingRound gutter length up to a maximum served length. Downspout lengthAdd vertical and horizontal route segments and stock pieces. Gutter service lengthEstimate served lengths from a selected maximum per route. Downspout extensionAdd route segments and round up to stock extension pieces.
Supports and fittings
Gutter hangersEstimate hanger count from run length and spacing. Gutter hanger spacingEstimate supports using a tighter selected spacing. Gutter end capsCount two end caps for each open-ended run. Gutter outletsMatch planned downspouts to outlet count. Downspout elbowsMultiply route groups by fittings per route. Gutter cornersAdd inside and outside corners from the measured perimeter. Gutter parts takeoffEstimate sections, spacing-only hangers, downspouts and outlets. Splash block quantityMatch selected surface-discharge outlets to splash blocks.
Size, capacity and collection
Gutter size selectorCompare listed half-round sizes against a rainfall and capacity condition. Gutter capacityCompare runoff demand with a candidate gutter capacity. Downspout capacity countEstimate how many downspouts a runoff rate requires. Maximum roof area for gutter capacityConvert candidate capacity and rainfall intensity into plan area. Gutter to barrel yieldEstimate rainwater volume available to a collection point. Roof runoff rateConvert plan area and rainfall intensity into cubic feet per second and gallons per minute.
