Drip Edge Flashing, Coming of Age in Georgia

Drip Edge Flashing

Coming of Age in Georgia


As of January 1st 2014 roofing installations required the use of drip edge flashing.  Prior to this roofing shingles were extended a longer distance over the edge of the roof in an effort to direct rain run off away from the fascia and building surface.  At the eaves or soffit end, the shingles extend over the top edge of the gutter to direct rain water directly into the gutter.  One of the problems with this, is that shingles extended over the rake edge often crack over time.  Also when, wind driven rain raises the edge of the shingle, the edge of the roof decking and the fascia board are left exposed to water damage.

Drip edge flashing is designed to go on both the gable (rake) edge and the soffit (eaves) edge of roof.  One of the most common shapes for drip edge is the D-style. The D-style has the benefit of the wider lip that goes over the roof surface, a shorter lip to support shingles and catch water and the lower flange bent outwardly to kick dripping water away from surface of the fascia board.

When drip edge flashing is installed at the rake edge the long top flange extends over the surface of the tar paper underlayment. In this way any rain that finds its way under the shingles is directed to the surface of the tar paper protecting the roof deck.  At the eves or soffit edge, the tar paper underlayment is lain over the upper surface of the drip edge. In this way any water that has made it to the surface of the underlayment will be directed over the surface of the drip edge and in the gutter.

Homes built in 2014 -2017 should have drip edge flashing installed.  During home inspections in Newnan, Fayette county, Henry county and Clayton county, Powerworks Inspections has found builders or roofers not keeping current code and installing drip edge flashing. Instead of installing proper drip edge, they are trying to get by with bending the top lip of the aluminum fascia out at a 90’ angle.

 While the 90’ bend does help support the shingle  it does not protect your roof deck by lapping back over the roof felt and does not stop wind driven rain from getting to fascia boards and roof decking.

When the shingle edge is lifted you see multiple wood surfaces exposed the potential wind driven rain. Drip Edge flashing would protect these wood surfaces and direct any wind driven rain, onto the surface of the felt underlayment.

Often during home inspections we find when this type of aluminum fascia is used instead of drip edge flashing we are left with exposed wood at the returns or at best the up 90’angle lip is directing water into the return instead of shedding water.

Drip Edge Flashing Review. Powerworks Inspections

I have discovered during home inspections of new homes built in 2016 and 2017 in Newnan, Henry county and Clayton county, that a number of builders or roofers are still not installing the drip edge flashing, but are installing only aluminum fascia bent out at a 90’.  This is not an acceptable practice and does not fully protect your roof. Make sure the home inspector you hire inspects your roof completely.
