The Proper Downspout Installation

We see it time and time again. Downspouts pouring out on to a lower roof which completely ruins the shingles. By doing this you essentially run a garden hose in one location of your roof every time it rains, accelerating the wear process of your roof. This problem is most commonly seen in newer subdivisions with cookie cutter homes. The eavestrough installer is getting paid a flat rate per house so they use as little material as possible, and get the job done as fast as they can. Cutting a corner like this can end up costing you, the homeowner, a lot of money in the long run. The water from the upper roof should never be allowed to pour out on to a lower roof. The only time you may consider it is if it is a small dormer or piece of eavestrough that will only collect a minimal amount of water. Below are pictures showing what I mean in regards to the downspout. If you ever have an upper eavestrough that drains down to a lower one, it must be ran all the way there in a downspout. By letting this water run across the shingles in one location with a much higher concentration than a normal rain you will wear out your shingles about five times faster. I have seen shingles have to be replaced in 5 years in this situation. I have also seen shingles with absolutely no grit left on them when the rest of the shingles on the house are fine.
