The 7 Most Common DIY Gutter Installation Mistakes

These days, there are plenty of resources for do-it-yourselfers if they want advice on how to complete a home improvement project. Many of them, like cable TV shows and online videos, give the illusion that every type of DIY job is very simple.

But in reality, most do-it-yourself projects are more difficult than they look. This is especially true of installing new gutters on your home. Here are the seven most frequently-seen mistakes in gutter installations:

  1. Improper pitch. Even though they look level from a distance, gutters should be pitched slightly from one end to the other. If the pitch is too gentle, water will just fill up in the gutters until it overflows, and a too-sharp pitch isn’t aesthetically pleasing. Gutters should slope an inch or two for every 40 feet.
  2. Forward tilt. That said, gutters need to be completely level from front to back, or water could spill over either edge. It’s not uncommon for homeowners to hang the gutters so that the front edge is slumping forward too much. Use a level when installing gutters and make sure all fasteners are tightly affixed.
  3. Wrongly positioned. Just hang the gutters on the roof’s edge, right? Incorrect. The guttering should run a few inches lower than your roofline. Gutters that are too high can enable runoff water to drip down their back side, which in turn can cause deteriorating fascia boards and stains on siding.
  4. Incorrect hanger spacing. You might try to slope your gutters correctly, but improperly-positioned gutter hangers can foil those plans and cause your gutters to sag in the middle. Make sure that there is no more than three feet of space between any of your gutter hangers.
  5. Too many seams. Like the weakest link in a chain, your guttering’s seams are the spots that tend to accumulate the most damage. Sometimes, gutter sections will even separate entirely. That’s why it’s vital to keep the number of seams to a minimum (or have seamless gutters made for you).
  6. Damage during installation. If you’re hanging aluminum gutters, you have to be extra careful during the installation process. All it takes is one hard blow from an errant ladder or a long fall to the ground from a roof and they can be bent or dented. Then you may have to replace the section altogether.
  7. Injuries during installation. Everybody feels safe and secure while they’re up on a ladder — until they’re not. Tends of thousands of people visit emergency rooms each year because of injuries sustained by falling off a ladder. So work with a helper, make sure your ladder is on solid ground, and never lean out too far while on the ladder.

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.
