Two feet is the general maximum length for a typical roof overhang.

How far should metal roof hangover.

Overhangs can vary from a few inches to a few feet depending on preference. Should i start from one side. Hi folks just a couple questions before i screw something up majorly on my roof. I am in the process of installing a metal roof on top of my existing roof.

That said overhangs can extend as far as 2 without the need for external supports. I currently have put 1x4 s on the existing roof for the metal to sit on. It can be made of metal. 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. Too much overhang and the shingles could blow off in high winds. Lengths of drip vary but typically it s sold in ten foot lengths 120. However the suggested width of an overhang is between 12 and 18 for eaves and no more than 8 for rakes.

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. Also i have a porch with a different pitch. 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. Some slight overhang is recommended in conjunction with a drip edge flashing to prevent water from getting under the roofing and onto underlying wood.

Gable end overhangs also known as rake overhangs extend all the way to the peak of the roof. Too little can allow water to seep into rake or fascia boards. Though most overhang regardless because of discrepancies of the facia being straight so they run metal past to let it appear straight. This will protect a roof from most types of damage.

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. A typical metal roof overhang may be 2 to 4 inches or even less. A brow roof is a narrow roof attached to the wall at the level of the first floor ceiling. I m a little unsure where to start.
