Drip Edge Details - Double Drip Edge With Gutters


Anyone else struggling with the best solution for blocking ice dams when using gutters? Best practice has been recommending wrapping the Ice and Water Shield down over the fascia, while Manufacturer instructions and warranties want the Ice and Water installed on top of the drip edge. I think I have a solution and would like to share and hear your thoughts on it. For anyone that can’t see the photo I will describe it:

It’s an extra layer of flashing (gutter apron) before the starter strip. First, as usual, a drip edge, but custom made with an extended 3” leg to block ice. Then ice/water shield as usual. Then, before shingles go on, a second gutter apron with a 2” leg, then shingles. The gutter will get installed OVER the 3" leg of the drip edge and UNDER the 2" leg of the gutter apron. This will direct rain water into the gutter, it will allow the gutter to have up to 1.5" of pitch while staying behind the apron flashing, and it will block ice dams from the possibility of reaching wood.

Thoughts?

Looks good but I have never had a problem folding ice behind the gutter or over a new piece of aluminum. As long as you close the seam between sheathing and fascia.

Also now that lag hangers are the norm we don't seep through loose spikes.

I work with a roofer that uses the 3x4 bend instead of wrapping the i&w over the fascia,no one around here use a gutter apron,like Tom says I usually don't have a problem with wrapping the fascia with the i&w but often times it's sloppily done and short at hips and valleys

2 of the guys I sub for staple the I/w to the fascia and then cover it with a 3x4 piece of aluminum to help protect from uv rays or something
Everyone else just staples to fascia and I go right over it.

Thats even worse. Your directing the water into the soffit. Which we know is a problem if non perforated

Wouldn't it run behind the gutter and on top of the fascia either way ? The I/w still goes over the fascia which goes down first.

Re: Drip Edge Details - Double Drip Edge With Gutters


Yeah it stays over the fascia but most soffit is nailed to the underside so if its not vented it holds some water.

When I go right over I/w the gap between the fascia and roof is covered isn't the soffit protected? Won't the melting just run behind the gutter ?

Re: Drip Edge Details - Double Drip Edge With Gutters


I was looking for a way to maintain the GAF warranty by following their installation instructions, putting the ice guard over the drip edge. No one around here uses gutter apron either. Luckily I found some at Menards so didn't have to custom make it. The angle is better bent on the apron and it has a 2" front face to stay down in the gutter.

Also, I'll be using aluminum fascia over the wood sub-fascia board. they 3" x 3" metal drip allows be to run the aluminum fascia under the drip. Another benefit is melted ice drips out over the aluminum fascia.

I have found wet window headers from soffit water rolling behind gutters and inside soffits. It's not going through the upper gap but redirecting it. It's not the right way to do it.

Interesting. I must do 200 houses a year with the I/c this way. I always thought it was pretty much standard for my area. Glad I'm just the gutter guy

Re: Drip Edge Details - Double Drip Edge With Gutters


Right or wrong I am glad the roofers here don't wrap I/W over the sub fascia.With as tight as they put drip edge on it would be even more of a fight to get the metal fascia on with I/W to deal with. It is bad enough that framer leave the roof sheeting hang over and have to deal with that.

Re: Drip Edge Details - Double Drip Edge With Gutters


Don't have ice dams here but it we always install the gutter below and behind the drip edge so that all the water running off the drip edge would run into the gutter. If for some reason an ice dam built up above the gutter and behind the roof drip edge (not sure why this would happen) the amount of ice would be pretty small I think. Would be interested in hearing where my thoughts are flawed on this one!

Re: Drip Edge Details - Double Drip Edge With Gutters


Ice dams are caused by improper venting. The gutter has nothing to do with it.
