Importance of Downspouts

By far one of the most common observations in regards to the roof system during a home inspection is the lack of downspout extensions. Unfortunately, current building codes do not require builders to install ideal downspout arrangements, therefore resulting in accelerated shingle wear and deterioration.

So what can you do to help improve drainage off the roof and prevent accelerated shingle wear? Your home inspector will likely recommend a simple improvement such as extending downspouts directly into gutters. In two storey homes or homes with various roof levels, drainage from up high can be discharged onto a lower roof such as the garage or front porch roof. Simple downspout extensions here can save you from increased localized wear and premature leakage.

One other important aspect to downspouts is ensuring they discharge far enough away from the foundation to prevent potential basement leakage. Every home is a little different, but in general if downspouts are extended at least three to four feet away from the foundation, you can greatly reduce the risk of having a wet basement problem.

Also, ensuring the downspouts are in proper working condition helps prevent leakage onto exterior surfaces which can cause unsightly staining all the way to brick spalling.

Chances are if you’ve had a home inspection your home inspector has probably made some sort of comment or recommendation about improving downspouts and roof drainage. Most improvements can be done by homeowners themselves with very little cost and will help them save money in the long run.
