Roger cook evaluates a couple alternatives for moving rainwater effectively.
How to divert water from roof valley.
How to redirect rain off a roof.
Score the surface of the drip edge with 80 grit sandpaper.
I don t know if you can buy them our guys just made them from scrap pieces of gutter.
It is screwed to the outer lip of the gutter.
Turn it upside down so the lip edge faces upwards.
Slide one end of the diverter tight to the bottom of the shingle tabs and leave a 1 in.
Place a piece of standard metal drip edge onto a table or between a pair of sawhorses.
Use flat pry bar to loosen stuck roof.
This is done to give the paint a better surface to adhere.
Thick bead of clear silicone caulk on the underside of the drip edge lift the shingle tabs up slightly and slide the diverter under the tabs.
The diverter solves this problem by collecting and redistributing water to the gutter system.
Spray paint bottom surface and up turned edge of flashing to match color of roof.
The way to reduce this is to use a diverter which is vertical piece of metal bent into a l shape with the bottom section about 3 4 wide and the vertical part about 4 wide.
Exposure at the other end to create a drainage pitch.
During rain all the water from large roof area is funneled into the valley overwhelming very small section of the gutter and causing overflow onto the surfaces below.
