How we estimate gutters & downspouts
Gutter estimates are measured along eaves from the roof plan, with downspout lengths taken from building heights on the elevations. Corners, end caps, outlets and hangers are counted separately because they add up quickly on complex rooflines.
Where the drawings show downspouts tying into underground drainage, the connection points are listed so they can be coordinated with the site contractor.
