Roof Eave Length

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.

Roof eave length.

Includes result for hip valley factor slope factor and the roof slope in degrees. The length of the overhang depends primarily on the climate. 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.

Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. Overhangs are common in most house designs providing protection against both wind and rain. 29 gauge galvalume ef3 eave flashing in white. If you add an eaves overhang dimension then the amount the rafter sticks passed the wall will be added to the rafter 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 base length width how roof pitch is calculated. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12.

The roof overhang length must be properly engineered to resist wind uplift. It is the length of this portion of the rafter. 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. Calculate the length of a rafter from the roof slope ratio of inches per foot and a building width measurement.

The rafter member will be longer. This is particularly true in geographical regions where high winds are a common issue. To accurately calculate the area of your roof you must first determine its slope or pitch. 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. 29 gauge galvalume gr2 gable rake flashing in gray. The siding underneath the overhang is known as the soffit. Drip edge flashing.

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.
