How Far Should Metal Roof Hangover

However the suggested width of an overhang is between 12 and 18 for eaves and no more than 8 for rakes.

How far should metal roof hangover.

Hi folks just a couple questions before i screw something up majorly on my roof. Though most overhang regardless because of discrepancies of the facia being straight so they run metal past to let it appear straight. That said overhangs can extend as far as 2 without the need for external supports. Too little can allow water to seep into rake or fascia boards.

Some slight overhang is recommended in conjunction with a drip edge flashing to prevent water from getting under the roofing and onto underlying wood. I m a little unsure where to start. This will protect a roof from most types of damage. Two feet is the general maximum length for a typical roof overhang.

A brow roof is a narrow roof attached to the wall at the level of the first floor ceiling. Metal is usually installed on rafters or strip sheathing rather than the solid decking used under other materials. There is a thing called wicking that if on a low enough slope will run up the underside of roofing and possible go up enough to get behind facia so usually without drip edge at least 2 with drip edge even. Overhangs can vary from a few inches to a few feet depending on preference.

Also i have a porch with a different pitch. Brow roofs are found on multi storey homes. Roof overhangs can extend farther than 2 feet but beyond this length they begin to lose structural integrity and require external supports. Should i start from one side.

I am in the process of installing a metal roof on top of my existing roof. Lengths of drip vary but typically it s sold in ten foot lengths 120. It can be made of metal. Drip edge varies in dimensions but typically the flange that nails to the roof surface is about 2 5 wide and the vertical edge that directs roof runoff down and away is about 1 5 in depth.

Gable end overhangs also known as rake overhangs extend all the way to the peak of the roof. I currently have put 1x4 s on the existing roof for the metal to sit on. A typical metal roof overhang may be 2 to 4 inches or even less. The edge of the shingles should hang over a roof between an inch and an inch and a half or between a half inch and three quarters of an inch if drip edge flashing is installed.
