Which Gutters Are Best for Heavy Rainfall?

Rain fall.
Does your area experience heavy rainfall? What kind of gutters might be most suitable?

It’s raining, and it’s raining some more. If the area where you live receives a lot of heavy rainfall, you may need to take a close look at your gutters. What do you need to do to make sure that your gutters don’t overflow during heavy rain? Getting the right gutter guards, downspouts, and gutters for heavy rainfall can make all of the difference.

What Is Heavy Rainfall?

How much rain is heavy rain? In certain parts of the country, it rains a lot. According to the US Geological Survey, heavy rain occurs when rainfall “greater than 4 mm per hour” falls in your area. Heavy rainfall is not even the top category for rainfall; your rain could even be greater than 50 mm per hour. That’s called a “violent shower.”

The Implications of Heavy Rainfall

What happens when it rains heavily on your home? For one thing, the areas around your home might flood, whether this is your yard or a local river.

However, even if the rainfall close to your home is less severe, your home can experience consequences if you don’t have a drainage system that’s well-sized for the job. If your downspouts or gutters are the wrong sizes, water will spill over the edges and run down your siding to your foundation, where it can cause the soil to shift. Shifting soil around the foundation will ultimately lead to concerns about cracks in the foundation. Your landscaping also suffers if you have water that consistently falls from your home to the ground.

No matter how much rain you receive, clogged gutters will cause problems for your foundation and landscaping.

What Gutters Are Best for Heavy Rainfall?

There are a few aspects to consider when thinking about what gutters to choose.

The amount of rain that you receive in a short time is key. It’s all right if it rains consistently but at a slow pace. However, if your area experiences sudden downpours, that’s when your gutters could overflow. One element to consider is the size of your gutter. Many homes have 5-inch gutters. If you get a lot of rain all at once, you may need 6-inch, 7-inch, or even larger gutters.

You also need to think about the pitch of your roof when you ask for an estimate. A roof with a steep pitch will send water shooting down the roof into your gutters. This means that even if there is not a lot of rainfall, your gutters could have problems. Consider this as you plan for the size of your gutters.

Additional Protection Against Water Damage

Protecting your home against gutter problems isn’t only about choosing the right size of gutter. It’s also about choosing the right products to go with your gutter. As you meet with your gutter company, ask them:

  • How many downspouts will you put in, and where will they be located? This will help move water down to the ground.
  • Do you install gutter covers? Adding the right gutter cover to your gutters can prevent them from becoming clogged. This, in turn, prevents them from overflowing onto the ground.
  • The Family Handyman suggests that you “add a splash guard at the bottom of roof valleys to prevent gutter overflows during heavy rainstorms.” What other tricks does your installer suggest to prevent gutters from overflowing?
  • What is your warranty? Just in case something goes wrong with the installation, make sure that you have protection against gutter leaks.

I have had Gutter Helmets for 20 years. In all that time I've never had a problem until recently a bird's nest found its way into one of my gutters. The installer who came to replace the product was the same installer from 20 years earlier. Now that's impressive. Everyone at Gutter Helmet inclusive of the office staff were professional and a pleasure to work with.

Gutter Helmet by Harry Helmet just replaced our roof and we could not be more satisfied. The crew showed up early, worked all day and stayed late, were professional and caring regarding the project and the surrounding impact it had on our property and home. They completed the roof quickly and it looks simply amazing!

VERY happy with our entire experience adding Gutter Helmet by Harry Helmet to our house. Installing this was a great value for us. The gutters are working perfectly in heavy downpours and with year-long leaves and debris coming down from our river birches. Terrific customer service and a first class product.

We needed our roof repaired due to wind damage. After several quotes, Gutter Helmet was the only company that went into our attic to look and see if more damage had occurred. If it wasn't for them taking the extra time to look at everything, we would have had rotting wood under our new roof. They were very professional and gave a fair quote.
