Roof Length From Edge House

Think of how a roof extends beyond the siding and then think about how a hard rain may roll down the roof and onto the ground away from the structure.

Roof length from edge house.

When you install the drip edge over this strip it keeps the lower flange further from the home s siding which helps to keep water further from the home. Centuries ago the eavesdrop was that indentation line made around a structure when the rain fell off the edge of the roof onto the ground. Anyone standing that close to the house on the. If this isn t practical then perform the same measurement on the underside of the roof.

The total run is the distance from the peak to the edge of the roof which in this case is the total width divided in half which is equal to 10 feet or 120 inches. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. Also known as a fascia. The space under the roof.

The run is the distance from the outside edge of a perimeter stud wall to the center of the house. Since pitch is the rise over a 12 inch run divide the run by 12 to get the multiplier in this case 120 12 10. Conventional slope roof range between 4 in 12 and 8 in 12. The rise is the distance from the top of a stud wall to the peak of the roof.

A low slope roof is anywhere from 2 in 12 to 4 in 12. The following tools estimate the area of a roof as well as the amount of materials necessary to construct a roof of a given area. Roof pitches are described in terms of rise and run. We included a roof pitch chart below the 7 12 example image and the calculator below that.

A furring edge is a strip of one by two wood you install on the vertical surface of the house just beneath the roof s edge. The house base area is the area of land that the house covers and for more complex shapes can be estimated using the area calculator. A roof s pitch is determined by how much it rises for every foot it runs. Drip edge vents are a two in one installation that promote water shedding at the eaves and rakes of a roof while also allowing for ventilation into the attic.

A drip edge vent is made of a corrosive resistant material that sticks out about three inches back from the roof edge and then bends downward over them. What should the minimum length of a piece of drip edge be. The attic must be ventilated to protect the roofing system against excessive heat in summer and warm moist air generated by the house in winter.
