How Far Should Gutter Extend From Drip Edge

Gutters should be hung where a straight edge laying on your roof shingles can easily extend over the front lip of the gutter this is the proper installment location for the high point of the gutter.

How far should gutter extend from drip edge.

Omitting the spacing between the fascia and the drip edge is a common mistake that contractors often make. While the vertical leg should be placed 1 4 1 2 away from the fascia. The correct placement of the drip edge is the top of the roof directly between the shingles and the fascia board. How far should a drip edge be from fascia.

A typical metal roof overhang may be 2 to 4 inches or even less. The back edge of the gutter should tuck up behind the dripedge if you have it otherwise the edge of the shingles should extend well over the back half of the gutter so the drips cannot get behind it and rot the fascia board. The lower edge of a roof should extend beyond the fascia board by about 3 4 inch so that runoff drains into the gutters. The roof leg should extend a minimum of 2 back onto the roof sheathing.

Some slight overhang is recommended in conjunction with a drip edge flashing to prevent water from getting under the roofing and onto underlying wood. Metal is usually installed on rafters or strip sheathing rather than the solid decking used under other materials. If this slight overhang is too short water will drip behind the gutters leading to rotted roof sheathing and fascia stained siding and even soil erosion and a flooded basement. It should be a minimum extension of two inch from the fascia board on the roof.

A normal gutter will have about 1 2 3 4 of its width sticking out beyond the shingles to catch the runoff.
