Roof Eave Length

Measure the length of the gutter where you want to stretch the cable then figure out how far to the nearest foot the eave extends beyond the exterior wall of the home.

Roof eave length.

It is the length of this portion of the rafter. Roof overhangs are the amount that the roof hangs over the top of the siding in residential home construction. The rafter member will be longer. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12.

If you plan to have overhang etc. By gibraltar building products 17 95. An eave is the edge of the roof that overhangs the face of a wall and normally projects beyond the side of a building. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.

The eaves may terminate in a fascia a board running the length of the eaves under the tiles or roof sheets to cap off and protect the exposed rafter ends and to provide grounds on which to fix gutters. 29 gauge galvalume gr2 gable rake flashing in gray. Overhangs are common in most house designs providing protection against both wind and rain. Pitch is the incline of the roof represented as the ratio of rise to the span twice the run.

It is often compared to slope but is not exactly the same. The roof overhang length must be properly engineered to resist wind uplift. In the united states a run of 12 inches 1 foot is used and pitch is measured as the rise of the roof over 12 inches. The length of the overhang depends primarily on the climate.

For example if the roof rises 4 feet and the span is 16 feet twice the run then the pitch is 4 16 or 1 4. Multiply the gutter length by four if the eave is roughly one foot by five for a two foot eave and by six for a three foot eave. Roof base length width how roof pitch is calculated. Calculate the length of a rafter from the roof slope ratio of inches per foot and a building width measurement.

If you add an eaves overhang dimension then the amount the rafter sticks passed the wall will be added to the rafter length.
