All about Gutters

Gutters are not something that you typically think of until they are malfunctioning.  They are very important though because when they are not working properly this can cause damage to your foundation or water intrusion in your basement.

What is the Standard gutter size?

 The standard K-Style gutter size for a residential house is five-inch.  You can also get this style gutter in six-inch size.  

In most cases five-inch should be sufficient, however, if you are having overflow problems six-inch may be a better option to move more water.

What are Splash Guards used for?

Splash guards are typically installed on inside corners of gutters or in an area where water is coming from an upper roofline.  These will help prevent water from spilling over the gutter in areas of high water flow.

What size downspout should you use?

We offer downspouts that are 2×3 inch in size and 3×4 inch in size.  If six-inch gutters are installed, 3×4 inch downspouts must be used.  You can also install the larger 3×4 inch downspouts on your 5-inch gutters.  It would be beneficial to use the larger 3×4 inch downspouts in all situations, these can handle more water flow. 

For proper drainage, a downspout she be placed about every 40 linear feet.

Should you have Leaf Protection installed?

Some benefits to using Leaf Protection are that you are guaranteed you will not have a downspout clog and that it is easier to clean your gutters with Leaf Protection. 

A common misconception about Leaf Protection is that it will make your gutters maintenance free.  Even when you have Leaf Protection installed, there will still be some maintenance.  They will need to be wiped off periodically.  Just keep this in mind when deciding if Leaf Protection is for you. 

At Carlson Exteriors, we use Shur FloX Leaf Protection. This is a product that is put on top of your gutter, it does not go underneath shingles.  It will not void any roof warranty you may have. 

Shur FloX only attaches to the gutter – not the roof.

When Should You Replace Your Gutters?

After a roof replacement – The best rule of thumb is to replace your gutters right after your roof has been replaced. When your old gutters are removed all the seals are broken. It’s hard to reseal old gutters once that’s been broken. If you keep up with the pattern of replacing your gutters everytime your roof has been replaced, you should not have any problems with your gutters.

Large Quantity of Rust Spots or Holes – Sometimes this can be repaired by sealant or a new section of gutters. But if rust or holes are consistent on every run of gutter, replacing your gutters will be better a choice to spend money on.

Sagging gutters are caused from improper pitch on gutters.

Sagging or Bowed Out Gutters – Sagging and bowing is caused by improperly pitched gutters. Water begins to pool and be held at sections of gutters; without being able to drain out the gutter sags at the weight of water over time. Once a couple sections are sagging, it’s best just to replace your gutters and make sure all runs have proper pitch to allow for drainage.

Flooded Basement – What a nightmare! And an expensive nightmare if you have a furnished basement. If your gutters are old and just aren’t making the cut your basement can flood. When your gutters aren’t channeling water away from your home’s perimeter, all that water seeps into your basement. Over time this can cause foundation damages too!

Wrong Size Gutters This can be hard for the average homeowner to decipher, but any contractor should be able to stop by (at no charge) to verify if your home has the proper sized gutters. Most homes come with the standard 5” gutter; however, if your home has a really steep pitch the water flow can amplify and overwhelm the 5” gutter system.

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.
