Is a drip edge necessary on a metal roof.

In other words it is the metal flashing located at the edge of a roof. The drip edge also gives us a nice straight edge with which to align roof shingles slates or other roofing material. It will stop the water from running back under the steel and dropping on the facia where it could cause damage. A metal roof may or may not need a drip edge.

Let s start with a definition. A drip edge is essentially a metal sheet that is shaped like an l. If the pitch of the roof is low then a drip edge might be a good idea. Why drip edge is a necessity.

A drip edge is a metal usually aluminum strip which extends beyond other parts of a roof and directs rainwater off the roof away from the fascia and into the gutter. The edges of a roof that receive the most moisture particularly those of irregular or steep sloped homes require the most protection and any shingles that extend beyond a certain point are going to eventually bend and fracture along the edges which means if the drip edge is missing or has been eliminated from an installation water can get under the shingles and cause staining and deterioration of the lower roof deck area and the band under the roof edge. A drip edge is a non staining and non corroding material applied on a roof s edge to give water the ability to filter out of the roof system.

This metal sheet is installed on the edge of the roof and directs water away from the fascia and toward the gutter. Drip edge is a vital component of a building s roof. There are several details that should not be missed during the installation. 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.

Without a drip edge water may end up beneath the shingles and may cause damage to various parts of the home. Drip edges are crucial in many cases because they protect important architectural elements from wind driven rain.
