If water is dripping behind your gutter it s probably because it was installed without any flashing over the back of the gutter.
Second story rain gutters drain.
If this is the case you may need to add a small section of downspout that connects your second story gutters directly into your first story gutters.
The gutter apron will prevent the dripping.
These will help provide a natural solution to your drainage problems.
Turn your problem into an advantage by creating a rain garden to manage water runoff.
This will eliminate all of the water from the second story getting dumped on the roof of your first story and it will instead run the water directly into the gutters.
Using gutters to remove water from upper story and lower story roof areas extends the life of your roofing material and diminishes the chances of leaks through walls and the foundation.
Home centers sell a gutter apron in 10 ft.
A gutter apron is a bent piece of flashing that tucks up under the shingles and over the gutter.
After snow melts it drips down from the roof onto the deck and freezes making an icy deck.
The gutter system you describe is problematic yes water from the clogged second floor gutters overflows onto the lower roof and the clean gutters and downspouts at the lower level transport the water away from the foundation a good thing but some of 5he water that overflows 5he upper level gutters wicks into the plywood or osb roofing the fascia boards and the structural framing supporting them causing hidden deterioration and encouraging insect infestation mold and other.
I m looking for a maintenance free solution to the icy.
Gutters should be replaced every 25 30 years or so.
