How to determine the proper gutter size for your home or business

How many of you know if you have the proper size gutter? SERVPRO of Pottstown/Souderton put together this handy guide on gutters.

5 inch K-style gutters or 6-inch half-rounds, are able to handle the rainfall on most houses in most parts of the country.

But houses with big, steep roofs or those located in heavy rainfall areas with heavy downpours may need wider gutters and extra downspouts to keep rainwater from overflowing.

First, you'll need to calculate the square footage of the gutter's drainage area. For a gable-end roof, you'll only need to make 2 calculations, one for each slope. Intersecting roofs have multiple facets. For those you'll need to add up the area (length x width) of each surface within a drainage area to get the total square footage. Contact a home improvement expert to offer help and advice so you don't have water damage. Always make sure down spouts are directed far enough away from the foundation to prevent water damage
