Both gutter aprons and drip edges should be strong enough to bear uv rays and moisture at the same time.
Gutters should my drip edge overlap my gutter.
Other causes of the water running behind the gutter if properly installed are roofing not extended 3 8 past drip edge improper overlap of drip edge ice and water membrane placed beneath drip edge.
Nail high up on the drip edge so that the shingles will cover the nails.
The correct placement of the drip edge is the top of the roof directly between the shingles and the fascia board.
In most cases you ll notice the problem as soon as you get a close look in your gutters.
If the overlap is too short fix it by placing drip edge under the first row of roof shingles and be sure that the exterior edge is reaching over the gutter.
The bracket screws should not be screwed through the drip edge.
If the gutter is lower than the bottom edge of the drip edge install flashing behind the drip edge and over the back edge of the gutter to remove the gap.
A drip edge is designed to take advantage of those forces and along with gravity direct water into the gutter.
Direct water away from fascia.
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.
The end with the flange or flare should point down and away from the roof.
Drip edges have two key purposes.
Clogs also generally manifest themselves in the same way by causing the water to back up and pour out over the sides and edges of the gutter instead of out the downspout.
The drip edge should be installed over a furring strip so that it tails off the fascia board.
It should be a minimum extension of two inch from the fascia board on the roof.
Due to cohesion surface tension and other forces water droplets tend to stick to one another and to the surfaces they are on albeit slightly.
In almost every instance gutter installers take the path of least resistance and shove the gutter right underneath the roof shingles instead.
Use roofing nails to secure the drip edge.
A gutter apron is of no use if not installed properly because you will have to consider other options for your roofing.
