Why You Need to Skip (or Ditch) Those Gutter Guards

Gutters play a vital role in protecting your roof. Without them, or when they are clogged, water will damage fascia boards over time and can get back up under shingles. Beyond your roof, proper water drainage is important to protect the rest of your home:

  • The soil around the house is stabilized
  • Foundation problems can be avoided
  • Flooding under houses and in basements can be prevented
  • Erosion can be prevented and this preserves landscaping and turf
  • Water damage to siding can be prevented
  • Water staining on brick and stone masonry can be prevented
  • Settling and cracking of sidewalks, patios, and driveways can be lessened
  • Exterior doors and garage overhead doors can be preserved

In an effort to have their gutters cleaned less often, many homeowners opt to install gutter guards. These, however, don’t usually solve the need to clean your gutters and, when they do need to be cleaned, make it more difficult.


The problem with gutter guards

In the Pacific Northwest with all of our tree species, we get a mix of broadleaf varieties and fir trees. That means plenty of leaf and tree litter which can easily get through the gutter guards or screens and more than can completely cover them so water cannot get through.

While there are varieties of guards which will help prevent leaves from covering them by using a curved design, that design creates a different problem. Small twigs and other debris can create a dam by building up against the raised portion of the guard.

Even if the gutter guards work as intended, there is still the issue of moss and algae growth. As long as a small amount of leaf material makes its way into the gutters, it creates the perfect growing environment for lichen and moss. Left unchecked, it will continue to grow. As it does, it can block downspouts or break free and clogged them.


You are still going to need your gutters cleaned, even if less often.

There is no way to prevent it. That is where the second big issue arises – gutter guards make it difficult to clean your gutters!

As good as they can be at keeping leaf and other debris out, they do a better job at keeping us out. In some cases, we may not be able to remove the screens at all. In this case, the choice to flush them out with pressure and get what we can or they will need to be replaced. If the brand you choose to install can be removed in sections, cleaning your gutters will be far easier, though far more time consuming as well. You may need to have them cleaned less often, but it will likely cost much more.

The best guards are the hinged ones. They are easy to ‘open’ to allow cleaning so not likely an added cost for the time. We still wouldn’t recommend these as they open away from the roof. That makes it difficult to clean your gutters from a ladder.


Gutter guards are not a great investment.

  • The best ones worth installing are expensive.
  • They can cause your gutters to be blocked even if they keep them free from debris.
  • Gutter guards will not prevent everything from getting in so they don’t prevent the need to clean your gutters.
  • They can make it more costly to clean your gutters when necessary.

Our professional advice is to skip (or ditch) those guards and set up a maintenance schedule to have your gutters cleaned twice per year. You’ll find it more effective and less expensive over time

    Leaf Filter does not attach to the roof, keeps all debris out, even shingle grit, does not prevent proper water flow into the gutter, and never has to be cleaned off, because the debris doesnt block the water flow. I can’t sell it to you or anyone else through commenting here. I am commenting because your article is incorrect, because that is true of every other type of gutter guard, but Leaf Filter actually works. Our customers go from cleaning their gutters twice a month in the fall to never cleaning them again. I havent touched mine in two years. No more ladder climbing or roof walking.

      There is an exception to many rules. In general, the information is correct. The other consideration is location. We have seen products work well for customers who have property in other areas yet the same ones did not here. With broad leaves and pine needles prevalent, we’ve seen issues with every brand, though some worse than others. The other concern in our area is the amount of rainfall and heavy at times. Anything that limits the amount of water which can get into the gutter itself is a potential issue. That includes products covering the gutters to keep leaves and debris out. As such, we do not recommend these products.

      Since the vast majority of our experience is that gutter guards are ineffective, we do not recommend them.
