        Have you by any chance had the opportunity to review a newcomer to the field, the only one recommended by one of our local gutter companies: One Gutter Guard

        I just went to their website. I've not tested it. I can tell you that based upon their interactive graphic it appears to install FLAT.

        If you install any gutter guard FLAT, it will fail. Debris will collect on top of it.

    Hi Tim,
    Thank you for your valuable insights into gutter guards. What do you think of GutterDome? This product seems similar to GutterShield? Can you give me an idea of what the total cost would be to install 90ft of GutterShield? I live in Ohio. Your help is much appreciated.

    I keep reading abut how well gutter guards keep debris out of the gutters but I also really need a product that will withstand the weight and damaging effects of heavy wet snow sliding off my metal roof! I don't have a problem with ice dams or icicles but the snow comes rushing down like a freight train!

    Hey Tim. Like so many others - thank you for doing such throurough research into the topics you cover. I had a question about the mesh gutter covers. One quote that I've recieved uses "Versa Guard". It's fairly expensive, and from the pictures I can see on their website, the slope is both a 2-3 inches lower than the shingles, and not as steeply pitched. They also look a bit like the ones that didn't work so well on your house. Wondering if you have any thoughts on the Versa Guard product.

    Thanks again for all you do!

      My thoughts are simple. Read all of my Gutter Guard columns and watch all my videos. It's crystal clear what to do.

    Based on your recommendation, we had MasterSheild gutter guards installed on our house about 3 years ago--120 feet at 3 different levels. We've visually inspected with binoculars on a regular basis to make sure debris didn't collect on top. However, we now have significant drip lines under all of them. This is so different from what we expected. Before I call the installer, do you have any advice?

    Thank you,

      Drip lines on the face of the gutter are to be expected. That's dirt and diesel engine soot washing down each time it rains.

    I live in Minnesota and would like to know how the gutterglove pro performs in climates that get a lot of snow. I am concerned about snow not melting fast enough on the mesh screen and creating ice dams. I know the company offers a heated version, but I don't want to pay extra as they can be quite expensive.

    With such a fine mesh screen, how does MasterShield perform in a heavy downpour? Does enough water actually get into the gutter?

    • Tim Carter
      May 14, 2014

      Once the first rain drops fall on the mesh, the surface tension of the water combined with gravity PULLS the water through the mesh.

      You have to see it to believe it. Rest assured the water doesn't flood over the mesh.

    Hi. A little distressed here. Had a handyman put up some gutter guards two days ago, and he left a few for me to do. So I was copying what he was doing. But within one minute I thought something was wrong, so I read the label on each guard. The handyman had jimmied up all the shingles around my mothers house she build with her own hands, about three inches worth up the shingle which to me as an uneducated fool, thought yeah that would compromise and expose the roof the the weather. Now what, and now that I have reviewed your site, I know the guards for 260 dollars were a waste of money, they clip on and have a concave shape that flip on top of the shingles. I had to sit down on the roof and cry out my 60 year old eyes that my roof was damaged, and I am not that endowed financially.

      Sorry to hear about this. The mistake you made, in my opinion, was NOT doing your research first before hiring this man. Had you come to my website in your research, you would have discovered those clip on flip gutter guards are decroted pieces of crap.

    Yep saw that, and I had already bought the guards, and this man was a friend of someone I trusted. I usually do my own work but been bed ridden for two decades and now have to rely on anyone who has mercy. Thanks anyway. I put the last of the crap pieces on the roof by myself, and I did notice they were indeed crap. Blessings

    Hi....I'm looking to install a gutter guard on my grandparents house but need one with minimal maintenance, for obvious reasons. I've seen ur video which is very informative. I did, however, hear of, I think they are called Rhino Gutter Guard, if I spelled that correctly, but not sure how good they really are. Have u come across this type of gutter guard and If so, what do u think of it? I'm seeking all the info I can possibly get to be able to make an informed decision. Ur help will be greatly appreciated.

    Did you test LeafsOut Micro Mesh gutter guard? Some of us are looking for a more reasonably priced, but effective, gutter guard as an alternative to MasterShield. I searched for the product in your archives but didn't find it. Thank you.

    Hi Tim, do you also endorse Klean Gutter, there is no Master Shield dealer/installer in my area. They told me this was a sister product and their website asks if I heard about from you? A google search did not find me an article where you discuss that product

    • Tim Carter
      June 24, 2014

      Who is "they"? Why don't you buy the DIY version of Mastershield and either install it yourself or have a handyman put it in for you? CLICK HERE and once at that page click the link next to the STOP sign at the top of the page.

    Tim, I just found your website, wish I had seen it a few weeks ago. We just installed a Leaf Filter System gutter guard for our entire home (3 bedroom colonial with gutters on first floor near the garage and kitchen, and then on the 2nd floor near all the bedrooms. We had our first rainfall the other day and I have to say I think the system performed horribly. Water repelled right over the top of the gutters as opposed to in the gutters themselves. I walked out of the sliding door in the back of my house and was doused with water! Can anything be done from a service and repair system, or should I get my money back and go to the Master Shield system? I spent over $2K and feel it was the worst purchase I have ever made. Your thoughts and advice are very welcome here. Thanks.

    Concerning those stains on the face of the gutter - I would surmise that since the gutters have to be installed at the same slope as the roof (thus the front edge is lower than the roof edge), that the diesel soot and other dirt has actually washed off the roof, over the gutter guard, and then down the front edge of the gutter. I may be a small percentage, not noticible in the rain, but enough over time for the grime buildup. I have never had any dirt and stain problems with any of my gutters (which went 10 years between painting). They have no guards (I have a single-story house, so gutter cleaning is no big chore). Sounds like the gutter guards may have solved one problem (having to climb a ladder to clean out the gutters) and created another (having to climb a ladder to clean the face of the gutters).

      It is very common to get "tiger striping" on gutters even without guards. There is a product called "Gutter Magic No. 9" that was created to clean the outside of your gutters long before guards existed. As an installer, I have experienced the fact that homeonwers do not pay attention to their gutters until they have been worked on. You just didn't pay attention if you didn't see the staining because it is very very common.

    was looking for an unbiased comparison of gutter guards but I see that you are paid a commission so concerned that this is less than a fairy valuation of all of those gutter guards available.

    • Tim Carter
      May 1, 2015


      This review is unbiased. At the time of the review and the TEST, I wasn't getting a penny from the winner. In fact, I don't get paid a penny to say what I've said in the above columns or video.

      That all happened BEFORE I decided to make an affiliate deal with the clear winner.

      If you think this is a biased review, then tell me what you think about the advice you get from:

      real estate brokers
      mortgage brokers
      a saleswoman at any store
      magazine reviews (trust me, editorial *is* influenced by big advertisers)

      If a BETTER gutter guard comes along, I'd tell you about it and try to make the same arrangement with them for a tiny commission.

      What I'm confused about is why you're upset about me getting a small amount of money for all the work I put in to be able to advise you as to the best gutter guard.

      All this information at is for free. How am I supposed to pay my bills and invest in my company if I don't get revenue somehow?

      I've got Amazon affiliate links on many pages for the BEST tools that I use. Is that wrong?

      Would you rather I put an ad on this page that says:

      "I tested all the gutter guards out there. I KNOW which one is the BEST and have the video footage to PROVE it.

      If you want to see the video and the TEST RESULTS, you have to PAY for them. It costs you just $19.95."

      Sharon, would you pay me the $19.95 or would you mumble, "Idiot, that information is free at other websites....."

      Do the other websites DISCLOSE the arrangement they have and are they as TRANSPARENT as I am?

    I just called the MasterShield company to investigate the addition of their gutter guards. While the product may work well, it is cheaper to pay someone to clean my gutters annually for 25 years (the length of their warranty) compared to installing their gutter guards. There are no options for hiring your own contractor or self installing to reduce the price. So, based on my research, this product is not cost effective.

      Really? The average gutter cleaning seems to be around $100-$200 per cleaning. Some homes may need to have that done two or more times a year. To be conservative lets say $150 x 1.5 = $225 x 25years=$5625 and that's a conservative figure for someone with large trees over their home. Now, how many times are your gutters going to be clogged with water running behind them, soaking and rotting your fascia board before the next cleaning? How many times are you going to have who knows who trampling over your old shingles? How many times are you going to wait around for the cleaners to show up? Are they insured? Have you checked with their insurance co to se if their premium's up to date? If they aren't and they fall.. Really? Cheaper?

    What do you think abut Leafguard and MyGutterPro?

  21. Anita

    We have a unique problem because our roof has a Mansard or Dutch Colonial design in the front and back and the roof shingles are practically vertical when they come in contact with the gutters (which are between the first and second floor). You state that "the manufacturer insists that the gutter guard be installed in the same plane as the roof". That is impossible. I know that the gutters would need to be lowered, but the plane will never be the same at the roof shingles. Would you still recommend using your favorite gutter "filter" under these circumstances? PS: I can send you a picture if you can't visualize what I am talking about.
    Thanks for your help.

    Tim, I do give you a lot of credit for disclosing that you get some compensation from Masterguard. And you are absolutely correct in replying to Sharon that there is bias in all sorts of recommendations including editorials. And you are fully justified in feeling that you should be compensated for giving advice. And I agree that not taking advertisements or commissions from products that you are reviewing prior to recommending one of them helps shields you from being biased in favor of one of them (unless it is known that one company is likely to compensate those that recommend their product).

    While I think it is very likely that you are sincere in stating that you are unbiased, I think it is unlikely that you remain unbiased in your promotion of Masterguard after being paid by them. And you are not likely unbiased in terms of whether to recommend no leaf guard product at all with there being no chance of remuneration.

    I am considering whether to get a gutter cover and if I do, which one to get. I am concerned about how many years (months?) of filtering the fine mesh screen on Masterguard and Gutter Glove have before they fail to work as well as in your videos. The Masterguard warranty is good against the "INTERIOR of the gutter" becoming clogged; NOT the cover failing to allow water through it-instead cascading over it onto the side of the house. Your recommendation not withstanding, I am going to stick with my plan to have no cover or one based on surface tension that Consumers Reports rates as being excellent at preventing buildup.

    My answer to Sharon would be to go to to get truly unbiased information. She would probably have to pay a subscription fee. It would be worth it. READ TIM CARTER'S RESPONSE TO THIS COMMENT JUST BELOW.

      Billy Bow Legs,

      Are you talking about the Consumer Reports magazine that failed, for over six years, to include synthetic-resin deck sealers in their annual deck stain study?

      Is it the same Consumer Reports magazine that FAILED to include MasterShield gutter guard - the product that passed my tests - in their study?

      Is it the same Consumer Reports magazine who's head editor refused to answer my questions about why they overlooked the sythetic-resin deck sealers?

      You give this publication far too much credit and faith my friend.

      As for my *bias*, my testing and report were done BEFORE I decided to make an arrangement to capitalize on the knowledge I discovered.

      It's no different from the hundreds of affiliate links I have here on my website that connect to FANTASTIC products at that I own and use in my own home.

      If you continue to follow the advice you get from Consumer Reports, I'm afraid at some point, you're going to get burned. But what do I know?

    Because of all your testing I too went with Mastershield and I can tell you I'm very disappointed in the product. Yes, the dripping that occurs during the rain, which we get a lot of in Vancouver, Wa. across the river from Portland, Or. get me wet every time I go out any of my 4 doors. I expected the neighbors maple leaves and seedlings to not accumulate ontop of the gutters and they did in many areas. I'm 74 and can't get up on ladders to brush them off.
    Also last week we had a snow storm that left the entire area with about 15" of snow. I'm the only one in the neighborhood who has icicle along my gutters that range from 4" to 29" and above my heat pump were the bigger ones along with about 3-4" of solid ice on top of the gutters.
    Any suggestions?

    • Tim Carter
      January 18, 2017


      Several questions: Did you take photos of the installation and send them to the owner of Mastershield? It's POSSIBLE the local installer didn't put them in the same plane as the roof. That's a must.

      Did you watch all the Mastershield installation videos before the workers showed up? You need to do that with *any* product to make sure the workers do the job right. You can't HOPE workers will do it right.

      As for icicles, you'd have that with or without gutter guards. Read my past column about that!

    Thanks for the research. I am interested in DIY installation of Mastershield but find no place on the link you supplied to purchase them. Only request for a quote to install.

    • Tim Carter
      February 6, 2017

      That's because Mastershield is dealer-installed. Call them up and ask for Karen. Tell her what you want. Be SURE to mention my name. It's the secret password to get what you desire.
