Granule Loss in Gutters

Finally got around to looking in our gutters on our new house, and I found 3/8-1/2" of granules and "dirt" at the bottom of the gutters. The roofing shingles seem to look like they have a lot of granules remaining, so should I be concerned about the amount in the gutters?

Do the granules/dirt affect water flow in the gutters? If so, what's the best way to remove the crud (e.g., use a shopvac, scrape it out, etc.)?

That amount of granules on a new roof sounds normal. Every time you clean your gutters you will see granules. It depends on where your gutters empty as to if you shopvac them or just flush them with a hose. If it could plug up the outlet then vacuum them if not wash the dirt out of the gutters. It will affect the waterflow some if the dirt and granules cannot be washed out by rain. As you may see on some houses that are never cleaning their gutters this buildup will even grow small weeds and trees. You can buy a gutter cleaning wand that looks like a big cane to wash out the gutters from the ground. No ladder needed.

Gutter Cleaning

When I clean my gutters of granules, I use the water hose.

Wash the granules and dirt away from the downspout. When it piles up, remove with a scoop or by hand. After the bulk of the debris is removed in this manner, then wash the remaining toward the downspout to get the gutter clean.

Granual shedding is normal for a new roof.

If I have leaves or other light debris in the gutter, I use the leaf blower.

Good luck with your project.

I do the same thing, hose it to one side and scoop.

>> "Granual shedding is normal for a new roof."

How long does it tend to "shed?"

On a side note, I see a neighbor on an adjacent road up on his with a pressure washer, talk about shedding, no telling how many years he is taking off his roof.

Good question because I was going to ask the same thing! I just cleaned my gutters the other day and noticed the same thing.

Apparently my roof is only about 5-6 yrs old and still has plenty of those granules on.
