Smile How to fix Gutter that outlets onto porch roof


I have two gutter outlets discharging onto the porch roof. This is causing moss growth and damaging the asphalt shingles on the porch roof.

Here is a pic:

Can anyone suggest a remedy? Can I extend the outlets to the main gutter collection point.

if you can post a little more info it would really help? how long is the main gutter that you would like to connect to? how long is the problem gutter? if your getting mold it could be because of leaves or pollen from trees over head, or water just sitting[ do to not enough pitch for water flow] an easy fix if it is possible ?is to install a new gutter on top of the porch[directly to the house] so that the porch only has to handle the water that falls in it?

You definitely do want to get that discharge off the roof, see the picture of the roof here:

Roof damaged by water from roof above - Paragon Inspections Chicago / Skokie Ill

for an example of what eventually happens when water from one area of a roof is directed onto another below in a concentrated manner.

Normally, the method used to redirect the water from the upper roof surface is to extend the downspout(s) to the gutter below and terminate them down into the lower downspout with an elbow. If there is sufficient water form the surface above you may need to install oversized gutters and/or additional downspouts at the roof below.

Nice site Thomas. Hard to read with such a smallish content area. Maybe you should widen the content area to accomadate larger print. Lots of wasted space on the sides.
