Gutter Downspout Pouring Onto Roof

I have also honestly not had a chance to see how the lower gutter systems on the houses with the extended upper downspouts perform when all that water channeled off the upper roof is dumped.

Gutter downspout pouring onto roof.

Is it alright for a gutter downspout from an upper roof to empty onto a lower roof. So it s a matter of what the home inspector or contractor considers acceptable. But instead of the water being led away from your home altogether the downspout leads the water directly onto another part of the roof. Sometimes gutters get installed so that they drain water away from one section onto the roof.

Gutter talk lets talk roof gutters and downspouts. When gutters and downspouts from an upper roof spill out onto a lower roof damage can occur to fiberglass asphalt shingles. Will concentrated water flow push the gutter off the roof. Whether it s curved and tweaked so water exiting it flows across the roof pretty smoothly or splashes onto it with some force will also make a difference.

Will the areas where you have upper downspouts pouring water into the gutters need to be secured with more gutter hangers or they should be good with the current hangers. Erosion might be visible in 1 2 years or less or potentially be less severe all depending on the amount. Your goals are to get water off the roofs and away from the house as fast as possible. The shingle grit on a shingle s surface can erode under a gutter outlet or downspout.

It depends on who you ask this question. To empty onto the roof surface. There is no building code citation that forbids a gutter from draining onto a lower roof.
