Does 2009 IRC require drip edge?

The IRC now requires a drip edge for all asphalt roof installations and provides direction for its proper installation. Underlayment must lap over the drip edge at the eaves.

Is drip edge flashing required?

It helps direct rainwater off of the roof, either into a gutter or onto the ground. Without the flashing, rainwater could adhere to the edges of the roof and saturate important structural components. Drip edge flashing helps protect the roof decking, wood soffits, and wood trim from rot.

Do you need a drip edge if you have gutters?

If drip edges were installed, rainwater would instead be diverted to your gutters. Now, you may be thinking, ‘If drip edges can do all of this, how come I only come across it a few times?” That’s because the installation of drip edges isn’t required, except for shingle roofs.

How far should drip edge be from fascia?

Drip edge height: 1 5/8″ Drip edge lip extension: 1/2″ Recommended drainage gap: 1/4″ (approx) spaced off of the fascia board.

Where should drip edge be installed?

Drip edge is installed around the whole perimeter of the roof. It is used to hold the underlayments down and create a watertight seal around the edge of the roof. Only the face of the metal is seen and is usually just white one to one and half inch stripe located right under the shingles and above the fascia.

Can drip edge be installed after gutters?

However, the drip edge can be installed at any time. The materials involved include: a ladder, a flat pry bar, a hammer, tin snips, eave stripping, and galvanized roofing nails. Something else to consider is the drip edge eave strip, which is often made of galvanized metal.

Do all roofs need drip edge?

The 2012 International Building Code (IBC) requires drip edges for that type of roof. Regardless of the kind of roof you have, we highly recommend installing drip edges. Keep in mind that improper installation of any roofing component can create gaps, rendering any waterproofing solution useless.

Should drip edge be tight against fascia?

A vertical drip edge lip extends down roughly 1 5/8″ and as Steve points out, should not be set tight against the fascia board or water may run behind the gutter and down the fascia, inviting leaks and rot.

What goes on first fascia or drip edge?

The correct placement of a roof drip edge is on top of the roof’s exterior cover directly between the sheathing and the fascia board, which forms a drainage gap between the drip edge and the fascia board. As a result, the drainage improves water flow and protects the roof from potential water damage.

What is the IRC rule for drip edge on a roof?

Section R905.2.8.5, Drip Edge, in the IRC spells out what the IRC requires: “A drip edge shall be provided at eaves and rake edges of shingle roofs. Adjacent segments of drip edge shall be overlapped not less than 2 inches.

What is drip edge and why does it matter?

From product selection to installation details, drip edge often takes a back seat to the shingles or to eaves flashing (see “ Drip Edge and Ice-Barrier Membrane ,” Mar/18). And that’s too bad, because drip edge has a large impact on how water-resistant the eaves and rake edges are and how well the water drains over the fascia.

Are metal drip edges required by code?

The International Residential Code (IRC) did not require metal drip edges along eaves and rake edges until the 2012 edition (See Code Requirements for Drip Edge, above). So depending on where you work and what code prevails in that area of the country, metal drip edges still may not be required by code.

Should you choose an extended-style drip edge for your roof?

The extended-style drip edge would probably be a better choice along the eaves edge of a low-slope roof so the water drips off the edge away from the fascia. Mike Guertin is a builder and remodeler in East Greenwich, R.I., and frequent presenter at JLC Live and DeckExpo.
