        Q:Will this adapt to any size gutter
        by|Jul 3, 2019

        Answer This Question

        A:  This guard will work with most residential gutters, though I recommend buying just one and seeing how it fits in your application. They are cheap enough. Note on effectiveness: If you have long needle pine trees (like white pines), or black birch trees, they both produce debris which get stuck in the guards and will require manual removal by using your hands and a brush. A strong gas powered blower will not remove these type of debris which get very well stuck in the grate holes. Also, in the fall after the leaves have fallen (we are in CT), you will, unfortunately, still need to clean off the tops of these guards (clear all the stuck leaves) if you want water to get into the gutters over the winter. There is no guard on the market which eliminates gutter maintenance, not even the expensive systems advertised on TV. They all eventually allow the gutters to fill up with debris over time, or otherwise become ineffective needing maintenance. I've experienced them all over the years being in the home maintenance business and also responsible for running a condo complex (30+ years). All this said, these guards are better than many on the market, inexpensive enough, and fairly easy to install if you are handy, so probably worth trying. Hope this helps.

          A:  I was able to use the gutter guard on all of my gutters which are mostly a standard size. They function great and stay in place. I couldn't be happier with this item.

              Q:could I use these on gutters with roof straps?

              A:  The gutter guards go partly under the shingles. From what little I know about roof straps, I imagine each roof strap would have to be removed in turn, the respective gutter guard installed, and the roof strap reinstalled over the gutter guard and shingles.

                A:  Not exactly sure what roof straps are but the way these gutter guards work the molded edge fits against the inside of the front of the gutter and the flat edge fits up underneath the roofing material - cutting required to get a good fit. This creates a sloped roof of sorts that goes from the shingles over the rain catching part of the gutter. Water can go through the metal grate but leaves and other debris stays on top of the grate and eventually falls off to the ground. This is not a perfect system as a little bit of leaf debris still finds its way into the gutter somehow. I have large maple trees in my yard and with these on I could use the garden hose to rinse out my gutters through the grate instead of pulling out handfuls of rotten leaves and then rinsing with the garden hose. hope this helps.

                  A:  I’m gutter roof straps are under the Shingles. They work great Easy to install some cutting involved. If your straps are secured on top the shingles you probably would have to cut around them or But them up to the straps. They’re heavy duty and strong. And not like the cheap ones that get push down After the First season. That do you more harm than good. This is my second year and you still look like the day I put them in.

                    A:  Dear Leafhater: I purchased two sets of these Gutter Guards and am VERY satisfied with them! As far as I can tell, The "straight" edge fits under the shingles and the "curved" edge connects over the lip of the gutter. So, the Guard goes OVER the straps. Hope this helps

                      A:  Hi, if you mean by roof straps, straps attached to roof under first coarse of shingles to support the gutter, them yes. You carefully lift shingles and slide these under, pull them toward front gutter flange and snap in. I also used some small stainless screws, pre-drilled the holes to make a snug fit.

                          A:  I would think you could with a little extra work to notch the front of the guards to fit around the straps as necessary. On the roof side, the guard should just slide on top of the strap and under the shingle, as normal.

                            A:  My guess is you can but you may have to cut a slit in the guard at that point. That's assuming the straps are exterior to the gutter. It is a lot easier without exterior straps because you can slide the guard into the previous guard. It's doable but more work, my guess.

                                A:  I would think so as long as you can slide the "roof" side under the edge of the metal roof. We are very satisfied with ours.

                                by|Jun 11, 2018

                                  A:  The guards have to be slipped under the asphalt shingles, then clipped to the gutter. I would think your metal roof has flashing in front of the overhang and would prevent you from sliding it under it. Not totally sure. Good Luck.

                                    A:  Hi Kim, first I would like to say that I think you should do your own research on this question and also get some advise from someone who installs metal roofs. With that being said, I installed this product on my 5" gutters with an asphalt shingle roof. I was able to carefully lift the shingles and slide the guards underneath then back down and out to be able to snap them into the gutters top channel. You will need a pair of metal snips and good leather gloves to trim/cut the end sections. They have worked better then I thought and look like a professional install. Also with zero cleaning that is still needed with a gutter guard/shield system that still allows some small twigs and leaves into the gutter and will still have to be cleaned not to mention the crazy cost of those products and still having to deal with the clean outs. As a note, I used a few small, (1/2") stainless screws installed thru this guard and the front top lip of the gutter. The screws are not seen as the gutter channel hides them. Also, I used small UV outdoor cable ties to join the sections. Good luck.

                                              A:  Don’t know. I used them with an asphalt shingle roof. They are a little tricky to install and you need a pair of tin snips to trim them to fit. They worked really well to keep leaves from clogging our gutters. They are also strong enough that they don’t fly off in a wind storm like my neighbors did (different brand).

                                                    Bought a pack of five of these gutter guards on a look-see basis before I plunked down some serious coin to cover all our gutters. . . FIRST IMPRESSION . I could find no fault with the quality, and the product looks nice and is sturdy. . . . UNFORTUNATELY... . Unfortunately, the product was sent with all pieces loose, and in a way-oversized box, without ANY packaging; leaving the fives pieces to rattle around and crash into each other during shipping. This resulted in distorting (bending) a couple of the gutter guards in the area where the guard locks onto the top-front inside edge of the gutter. The powder-coated finish was unscathed, so, that says something about the toughness of the finish. With the help of a wood dowel, the damaged gutter guards were bent back into shape, and from the ground you cannot tell which guards were repaired. Yay me!!! But no packaging? Really?! . . . INSTALLATION TOOLS . 2" wide Scraper Putty Knife; to aid in the insertion of product under shingles and when overlapping guards. Use with care so as not to damage shingles nor gutter guard. . Pair of metal-snips/aviation-cutters; to cut guards, to accommodate gutter end caps and gutters that go around corners. . Combination Square -or- Roofers Square; to mark a 45° line for cutting gutter guards when accommodating gutters that go around corners. . Pair of leather work gloves; to be worn while snipping is a good idea. If not gloves, consider a first-aid kit, as cut steel of the expanded wire mesh can slice and puncture skin. . Two 8-or-16d nails; to be inserted into expanded metal mesh of gutter guards for final positioning of gutter. (see photo) The slick finish of gutter guards makes repositioning by hand a challenge. Consider applying a wrap of electrical tape around the nail shank to protect the powder-coating finish of the gutter guard. The installation instructions suggest using a "flathead screwdriver." If you go this route, consider using a phillips head screwdriver, as this type of screwdriver does not have a flare at the working end of the driver that could damage the powder-coated finish of the guard. . . . INSTALLATION . After I knew what I was doing and what tools I needed to do it, installation was fast and easy, and almost fun. Each guard took less than a minute to install. . . . FUNCTIONALITY OF PURPOSE . This is the weak area of my review, as the guards were installed during the tail end of winter...so, no falling leaves. However, my confidence is high, and I will be ordering and installing these guards for the gutters of the main house, the workshop, and one of our large outbuildings. I am not certain if an update to this review is possible, but if it is, look for my comments come this (2017) fall. .

                                                      first note that the holes in the invisa-flow are smaller than the 5" lock-on. That is a good thing, I got a few from the store- the lock-on, for a test. They work better than the plastic ones. I then ordered on line and got the invisaflow, the smaller holes are better, they dont trap stems and leaf edges near as much as the others. Super easy to install, well for me...the first few I was trying to force under the metal, but since I just put on a metal roof "ah-ha" I tuck the gutter guard under the metal and then screw down the end = trapping the guard in. As for the ends, cutting is easy with snips, I cut into - but not across, then trimmed off to fit, bending the trimmed part down. Thus creating a barrier to keep birds and critters out. Corners would be very easy too, place- mark- trim- pop in place. Very few leaves stay stuck for more than a day, wind blows them off eventually. I have not been on the roof in a month, and have not cleaned the gutter guards at all. What you see in the "after 30 days" is the result. Sort of a self cleaning kind of deal. Highly recommend these. (been over 6 weeks now, late fall. awesome)

                                                        I installed these to catch the oak tree catkins and leaves. So far the catkins collect on the top but can be swept off pretty easily. The first time it rained before I swept them, the rain shot over the top of the gutter. Still less messy than scooping the muck out of the gutters.

                                                        I bought these last year for one section of the roof to see how they performed--They worked well so I bought another section--As I installed these I got better and better with the installation--The final section took me half the time of the other two--I used a wide putty knife to get under the last row of shingles, then inserted the section of gutter guard under the shingles, bent the section, a little at a time until all the lip was in place--Make sure you can slide the entire section at least 4 or 5 inches horizontally--This will insure that you will be able to overlap the sections--When I got to the end of the gutter, I measured for the last piece (you never make it exactly with the 3 foot sections) and cut it to fit using wire cutters--I have included pictures which show the huge amount of leaves that have already fallen on the ground this year and sections of the gutter guard in place--Leaves will fall, some stay on the gutter until the wind or rain take them off the roof--Even if some leaves stick on the gutter, the rain flows, the gutters are never clogged because there are no leaves in them--I've had them on for my second fall season and have provided minimum maintenance--In areas where sticks and twigs form a little dam on the gutter, a little brush off will clear in no time--P.S. Wear gloves for installation
