How Far Should Metal Roof Hangover

Also i have a porch with a different pitch.

How far should metal roof hangover.

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. They are essentially mini roofs designed to protect each storey of the home individually. Metal is usually installed on rafters or strip sheathing rather than the solid decking used under other materials. I currently have put 1x4 s on the existing roof for the metal to sit on.

I m a little unsure where to start. 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. This will protect a roof from most types of damage. Overhangs can vary from a few inches to a few feet depending on preference.

Should i start from one side. Two feet is the general maximum length for a typical roof overhang. A typical metal roof overhang may be 2 to 4 inches or even less. Roof overhangs can extend farther than 2 feet but beyond this length they begin to lose structural integrity and require external supports.

Though most overhang regardless because of discrepancies of the facia being straight so they run metal past to let it appear straight. Brow roofs are found on multi storey homes. A brow roof is a narrow roof attached to the wall at the level of the first floor ceiling. It can be made of metal.

That said overhangs can extend as far as 2 without the need for external supports. Too much overhang and the shingles could blow off in high winds. Some slight overhang is recommended in conjunction with a drip edge flashing to prevent water from getting under the roofing and onto underlying wood. Lengths of drip vary but typically it s sold in ten foot lengths 120.

I am in the process of installing a metal roof on top of my existing roof. However the suggested width of an overhang is between 12 and 18 for eaves and no more than 8 for rakes. 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.
