It’s time to replace your gutters and you’ve been hearing all these things about 6″ gutters; so, is it worth the money to expand the size of your gutters and downspouts? What are the benefits of that extra inch? What are the drawbacks?

In the past, residential homes have 5″ gutters and 2″x3″ downspouts and commercial buildings have 6″ gutters with 3″x4″ downspouts. Currently, we are seeing more residents expand their downspouts to 3″x4″ and some even install the complete 6″ gutter system.

Pro’s in having a 6″ gutter system:

  • Able to handle/carry more water
  • Less downspouts
  • Easier to clean
  • Debris passes through easier (not to be confused as self-cleaning- the openings are larger so debris has more room to be flushed through- 6″ gutters are not self-cleaning)

Con’s for installing a 6″gutter system:

  • Costs more to install
  • Fewer installers have the equipment necessary to install
  • Debris can still build up
  • Can be seen as an aesthetic drawback by being larger in size

Like with any home exterior product selection, you need to take in consideration your situation (surrounding trees, roof steepness, etc.), climate, and rainfall density. A 6″ gutter system is more durable against strong storms by being capable to carry more water but if you live in a fairly dry part of the country, water carrying capacity is not a priority of yours. If you don’t want to make the leap completely into 6″gutter system, or can’t find an installer capable, try 3″x4″ downspouts instead of your 2″x3″ downspouts.
