Customer Questions & Answers

What is the best placement of the back of the gutter guard?

The directions say to place the back side of this gutter guard against the "back lip of gutter." I'm wondering if the back of the gutter guard can alternatively be place under the shingles without voiding the shingle warranty? The under-the-shingles approach would be an improvement, it seems to me, because then debris will be less likely to be captured between the back of the gutter guard and the shingles.
Asked by: Bobby
We live in the woods with massive amounts of 30ft+ trees all over, including several within 8ft of the house (been here almost 15yrs now). Used to have to completely clean out the gutters & downspouts every 3 weeks. I slid mine up under the shingles, between the shingles and the drip edge. Then pull them forward till they lock/snap into the front of the aluminum gutter. Everywhere two meet (end to end) I overlapped them just enough to get a brown gutter screw in through both (using a drill to make a pilot hole in the aluminum gutter). Been 2 yrs now. No damage to the shingles or roof...and no plugged gutters! Wish I'd have done this YEARS ago.

Is the 441-503br the right gutter guard for a 5" k type with a metal roof?

I need a gutter guard for my 5" K Type gutters. I have a metal roof on my house and want a good guard. I called your company and was told that the number 441-503 BR is what i need. Is this true?
Asked by: Oldman
Mine is 5" k type. But depending the roof type, mine is S tile, I put under the tile as tile is hanging over gutter. The guard would be tug under tile and above the gutter with tension against the front of gutter.

3 ft. Brown Lock-On Gutter Guard is rated 4.4 out of 5 by 19.

It is flexible enough to tug one side under tile and the felt paper. The material seems to be long lasting when comparing to plastic or other galvanize steel. In my case, it is quite easy to install without using any nail and bracket. I put up over 90 pcs on my gutter in two days.

Rated 5 out of 5 by from Great product Easy instal, good quality, lets lots of water thru and seems to stop the leaves. Good quality powder coat. Really nice. Needed about 300' for my house about $2,000 less than the gutter company quoted me for an instal of their guards on my roof.

Rated 3 out of 5 by from Could be better Pros: Sturdy metal construction. Easy to install. They fasten easily and really stay in place (not worried about winds blowing them off). I haven't used them in the winter yet, but I think they'll be fine. Cons: The mesh is just large enough to keep out leaves and twigs but not small enough to keep out maple seeds. They stick straight up and look terrible. I have to vacuum hundreds of them and eventually glue down a finer mesh over top to keep them out. It will be another project. (Ironically the mesh I will be gluing down is coming from the old Amerimax plastic gutter guards that wore out. Why they didn't apply the finer mesh to these new metal ones is a mystery.)

Rated 5 out of 5 by from I just installed 215 ft of this, very happy so far My rancher has 215' of gutters. It's mostly rectangular, but there's one portion that protrudes out further (I don't know the architectural term). So I have 8 90-degree corners in the gutters, 6 are convex and 2 are concave. The roof has a low angle (not steep), so I was able to sit near the edge of the roof and install these from above without needing to move the ladder at all. The installation was nice and easy. I lightly lifted the asphalt shingles and the metal drip ring and inserted the gaurd. Then I'd slightly bend the guards upwards and push the clip end into the rim of the gutter. Some went in pretty easily, others took a small amount of wrangling. After the clip was on the rim of the gutter, I used needle nose pliers to grab the back of the guard (the part opposite the clip on the rim of the gutter) and pull the guard upward to snap it onto the top of the gutter. This worked surprisingly well. The clip part of the guard has a notch that makes it easy to over lap about 1/2 inch of the guard next to it. Sometimes one guard was higher than its neighbor and I'll probably use some metal twist ties to close this gap so small leaves can't get blown in. Tin snips are pretty much essential to cut the guards at the corners. The job was done in about 5.5 man-hours for 215 feet of gutter. I'd recommend picking up some gutter hangers to pull some sagging gutters closer to the house ( If the gutters are slightly bent away from the house, then guards will not snap into place well. All done for a little over $225! It's hard to tell these are installed on my house, even when standing on my driveway thats slightly higher than grade level. NOTE! While researching gutter guards, I did read that guards with openings this wide may not effective against pine needles. I only have deciduous trees around my house, so it wasn't a concern for me.

Rated 4 out of 5 by from affordable solution After doing my homework, I opted for this solution to my gutter cleaning problem. Professionally installed gutter covers can cost thousands of dollars and don't always prevent water from spilling over near your foundation during heavy rainfall. I have a long long run of gutters and lots of maple trees around the house too. These cost me less than $300 (I needed 97 to go all the way around my house) and I was able to install them myself (57 yr old female) in just a few hours without tools (except the tin snips to cut pieces to fit at the end of each run), since the guards clip right on to the back edge of the gutter . There are less expensive plastic ones, but some of the reviews said they don't hold up well in the sun. These weren't much more, but they are coated metal. The openings are bigger than the plastic ones with screens, so some leaves get caught in the mesh, but the important thing is the water still runs into the gutter and down the spouts unimpeded. The leaves that get caught in the mesh have been minimal and any that aren't cleaned off in the wind, I can brush off easily from the ground. These are made very well, so that they fit together easily with a built in 1/2" overlap (I had to go back and buy a couple more because I forgot to figure in those overlaps, which added up to almost 50" for the length of gutter I had to cover!). They also cut very easily with a pair of tin snips to fit at the end of a run. They fit my gutters perfectly. The only problem I had during installation was in a couple places where the gutters had been nailed in too much, narrowing the width of the gutter, but I was able to fix that as I went along. I used the brown color to match my shingles rather than the white, which I thought might look dingy after they had a chance to get dirty, but you really don't see them from the ground anyway. I think these will do the job well and saved me a lot of time and money. The only reason I gave these a 4 instead of a 5 is that some leaves do get caught in the mesh, and because they are new, I haven't been able to assess how they will hold up over time. I will try to update my review after a year of use.

Rated 4 out of 5 by from Good quality product I bought these because of the powder coating (no rust I hope) and the sturdiness of them as opposed to the plastic ones that look like they couldn't withstand much of a snow load without collapsing into the gutter. Despite the directions for installation, I reversed mine so they locked onto the lip of the gutter in the back not the front. I tried installing the way they suggest and the back of the guard would slip into the gutter with very little effort. I also did not want to rest the edge on the roof because I have had issues with ice backup and this would definitely contribute to that. By reversing them I was able to flex them and have them lock into the front of the gutter nicely while the back with the lip on it locked into the lip of the gutter at the back. Made for a nice tight fit with a slight bow to it. Still not visible from the ground. Easy installation for a 61 year old female. Time will tell how well they hold up.
