WHY CONNECT UPPER GUTTERS TO LOWER GUTTERS

The idea of gutters is to collect and contain the rain water and then re-direct it away from the home. Otherwise the water would come off of the roof and wear a trench around the home and flood the home. Gutters collect the water from the top of the home where the downspouts carry it below. If there is a roof below and the downspout let’s the water go on the roof it usually will cause problems. Especially if the upper roof is big and there is a lot of water coming down the pipe.

WATER DAMAGE TO ROOF OR SHINGLES

One of the most important reasons to connect the gutters with downspout extensions, is water damage to the roof. When all the water from the Upper roof gets collected in the gutters and comes down the downspout, it has built up a little speed and force. That water washes away shingle grit and eventually damages shingles to the point that they will curl up. Once this happens the shingles become ineffective and your roof is now vulnerable to rot, leaks, mold, moss growth, etc…

Excessive water pouring onto the roof will cut the life of your roof in half or maybe more. For example, a 30 year roof is going to be lucky to last 15 years under these conditions. Check out these example photos below of shingle damage caused by downspout run off.
