Roof To Gutter Overhang
I have the same problem but in my case the roof sticks out 18 so i simply drilled small holes at the end of the roof and attached wire loops to hold the gutter in place.
Roof to gutter overhang. The gutter apron will prevent the dripping. Metal is usually installed on rafters or strip sheathing rather than the solid decking used under other materials. Hopefully the photo will illustrate the problem. Some slight overhang is recommended in conjunction with a drip edge flashing to prevent water from getting under the roofing and onto underlying wood.
Home centers sell a gutter apron in 10 ft. If the overhanging gutters have been in place for over 20 years then the owner may have acquired a prescriptive right for them to be there. In almost every instance gutter installers take the path of least resistance and shove the gutter right underneath the roof shingles instead. Since there is only about 3 4 of vertical material to anchor gutters clips are there any specialty hardware or other techniques to hang gutters along this facia.
If water is dripping behind your gutter it s probably because it was installed without any flashing over the back of the gutter. I have a roof that only has a sort of moulding that transitions from roofing to the walls. The bottom tile or slate of the roof covering should project at least half way into the gutter the ideal distance is between half way and two thirds of the way over. The deeds to the house may specifically provide a right for them to be there.
A typical metal roof overhang may be 2 to 4 inches or even less. A gutter apron is a bent piece of flashing that tucks up under the shingles and over the gutter. 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. If you can get or make brackets long enough yes screw them to the wall.
