MasterShield Gutter Guard Review (With Photos)

This MasterShield Gutter Guard review details the replacement of my old 5 inch rain gutters with new 6 inch wide gutters and the installation of MasterShield Gutter Protection.

Clogged and Poorly Installed Rain Gutters

The 5 inch wide rain gutters on my house were the original “builder grade” gutters that had several problems:

  • Improperly pitched (or sloped) gutters that wouldn’t drain properly and hold water.
    Matts of algae grow quickly in standing water and breed mosquitoes.
  • Poorly placed downspouts that made the water to run the full length of the house and around a corner to reach a downspout.
    The gutter would overflow at the head-end during heavy rains.
  • 2nd story downspouts that drained onto the roof instead of being piped into a 1st story gutter.
  • Sagging Gutters: For a gutter on the 3 story side of the house with difficult access, the lazy home builder spaced the gutter spikes over 10 feet apart causing the gutter to sag. Gutter spikes should be spaced not more than 4 feet apart and 2 foot spacing is recommended.
  • Gutter spikes that worked out over time due to flexing of the gutter.
    Spikes (which resemble very large nails) lack the holding power of gutter screws.

Removing the old 5 inch gutters and installing new 6 inch gutters with redesigned downspouts, proper drainage pitch and hidden hangers spaced 2 feet apart remedied the above gutter problems.

Do It Yourself Gutter Covers

My home is surrounded by a variety of Oak, Hickory, Sweet Gum and Tulip Poplar trees which shed twigs, leaves, “helicopter” seeds, flower petals, catkins, nuts and vast amounts of pollen. The roof also gets wind blown pine needles from trees over 100 yards away. The oak catkins are probably the worst, forming large tangled clumps and mats in the Spring.

I’ve tried several of the Do-It-Yourself gutter guards with mixed results.

  • The bullnose style gutter covers that wick rain water by surface tension while shedding debris kept out the worst part of the leaves, but seeds and smaller items still made it into the gutter, only delaying the gutter cleaning by a two or three seasons. During heavy downpours, the surface tension isn’t strong enough to wick the water into the gutter causing the water to overshoot the gutter.
  • The hinged wire mesh clip-on screens do a decent job and are cheap and easy to install, but don’t fit well on corners and cause leaves to pile up on the roof along the screen until it eventually rots away (in theory). I also had many problems this winter with gray squirrels running inside the gutter and flipping open the screens as they try to find a way into the attic (the drip edge flashing now prevents that!). I’d get on the ladder with a long pole and flip the screen back over. However, once the screen is flipped open, the clip moves and the screen won’t lay flat against the roof allowing leaves to slip under. This is a particular problem with high areas where my 24 foot ladder won’t reach the gutter.

Here’s the original 5 inch gutters with the clip on wire mesh screens:

Leaves and debris tend to accumulate on the flip-up wire screens. I run the leaf blower during the Fall season on the more accessible parts of the roof, otherwise the leaves would be a lot worse here:

This three-story high section of the old 5 inch gutter is reachable only with a 40 foot ladder. As noted in the photo, a squirrel has knocked open a the inexpensive clip-on gutter screen. The workman discovered the gutter was full of water and sagging because the lazy home builder skipped 10 feet between the gutter spikes. The gutter was punctured to drain the water before removing it from the house. I had noticed rain water would overflow the gutter and now I know why.

This is what was inside that high section old 5 inch gutter once it was on the ground. The wet matted leaves in the bottom were compressed like cardboard.

Clip-on wire mesh gutter screens and bullnose gutter covers are far better than nothing; it’s a tradeoff between appearance, cost, maintenance and effectiveness.

Why I Don’t Hire Gutter Cleaners

When I first bought the house, the gutters did not have any type of gutter covers and the former homeowner’s would hire a gutter cleaning company for around $250 to do the job. A rope team would climb the steep 10/12 pitch roof to blow the leaves out of the gutters. I hired gutter cleaners for couple of seasons, until I happened to be home one day and watched the gutter cleaning company at work on a neighbor’s home. The problems were:

  • The rope team would surf down the roof, damaging shingles and shedding showers of granules.
  • The ropes would snag on the roof vents; the gutter cleaners didn’t seem to care as they tugged and pulled on the ropes.
    I had a box vent broken this way.
  • If the leaf blower didn’t do the job because a twig, kid’s toy or matted leaves were stuck in the gutter, the crew couldn’t be bothered to reach a hand into the gutter to dislodge the debris.
  • At the time, I didn’t have drip edge flashing and the leaf blower would send a good deal of debris through the carpenter’s gap into the soffit.

A homeowner usually can’t inspect the high inaccessible gutters or see what’s happening on the roof, so there’s rarely any penalty if the gutter cleaner company fails to use due care or does a poor job.

Why Choose MasterShield Gutter Protection?

There are a huge variety of gutter covers on the market in almost every conceivable configuration including brushes, foam filters, bullnose style surface tension and screens. How to did I choose MasterShield Gutter Guards? I made my decision by studying numerous online reviews, manufacturer product and warranty specifications:

Ultimately, I choose MasterShield Gutter Guards because:

The MasterShield Gutter Guard is composed of interlocking sections about 47 inches in length and is available in a variety of colors to match your home:

MasterShield is about 9-1/4 inches wide. The left side slides under the shingles and over the roofing felt. The stainless steel micro-mesh allows rain water through while keeping out debris and shingle granules. The break on the far right is a drip edge to keep water from streaking/staining the gutter.

Mastershield Atlanta – KTL Home Improvement

MasterShield Gutter Protection is professionally installed by authorized dealers. A great product won’t make up for a poor quality installation. After contacting MasterShield for a quote, I received great service and quality workmanship from MasterShield Atlanta – KTL Home Improvement, the MasterShield authored dealer for the Atlanta, GA area.

Kevin Bowers, Owner & General Manager for Mastershield Atlanta – KTL Home Improvement, was very helpful in a review of my home’s existing gutter system and recommending design changes to fix the home builder’s gutter problems as noted at the beginning of the article. He explained that the old 5 inch gutters would need to be lowered to match the steep roof slope for optimal MasterShield Gutter Guard performance. The clincher was the quote for installing new 6 inch gutters was only about 10% more than just the MasterShield alone. He explained it’s almost easier to start fresh and install new gutters compared to lowering and adjusting the old gutters. It was a deal I couldn’t refuse knowing the problems with the old gutters.

Kevin and his crew arrived on time and completed the job at the quoted price, which included the replacement of a rotted section of fascia board with rot-proof PVC fascia board at a reasonable extra cost. I spoke with Kevin’s crew and watched as they worked. It was clear they had a well-practiced system and were meticulous in their work.

MasterShield Gutter Guard Protection Cost

The MasterShield installation on my home required 2 days and consisted of:

  1. Remove the old 5 inch gutters.
  2. Caulk the old gutter spike holes in the fascia board with Geocel sealant.
  3. Replace a 12 foot section of 1 inch by 8 inch rotted fascia board with PVC fascia (at my request).
  4. 256 feet of new 6 inch gutters with hidden hangers spaced 2 feet apart.
  5. 24 feet of new downspouts tied into the lower gutters.
  6. 256 feet of MasterShield Gutter Guards.
  7. Big Mouth Valley Blocks at the inside corner roof valleys for high flow areas.
  8. 1/4 inch wire mesh screen on all open elbows to keep out the critters.

I also received a MasterShield Limited Lifetime Product Warranty and 25 year KTL Home Improvement dealer workmanship warranty.

The cost for the MasterShield Gutter Guard was comparable to the other high-end professionally installed gutter guards. Your cost will depend on the total feet of material, complexity of your roof (my roof is high/steep with many ridges, valleys and cornice returns), new gutters and/or downspouts and any trim repairs.

The MasterShield Gutter Guard has a low profile when viewed from the street and blends with the gutters. The new 6 inch gutters cover most of the fascia board which means protection from the weather and less painting.

Big Mouth Valley Block

A challenge for gutter guards are handling high water flows on inside corners at the bottom of roof valleys. MasterShield Atlanta – KTL Home Improvement installed the patented Big Mouth Valley Block by Guilford’s to solve the problem. The Big Mouth Valley Block provides a large screened area to capture the high volume of rain water.

Gutter Downspout Improvement

The old gutter downspouts were positioned on the sides of the house for the longest possible distance for the water to travel. KTL Home Improvement recommended moving the downspouts to the front corners with the new 6 inch gutters, with tie-ins the gutters on the 1st story as shown:

I requested the new 6 inch gutters stop short of the roof valley on the back of house to allow the huge amount leaves and debris to fall past. This side of the house faces the backyard so appearance aren’t critical.

The old downspouts emptied onto the roof corresponding the inset of the above photo. Oak tree catkins, helicopter seeds and leaves are funneled to this roof valley. At times, I’ve observed a mound of debris much much larger than this hanging over the gutter. This photo was taken a couple of years ago before the roof was replaced.

MasterShield Gutter Guard Drip Edge

The MasterShield Gutter Guard features a drip edge that extends beyond the front of the gutter to shed water and avoid rain streaks on the gutter. The ends of the gutter are covered with aluminum plates to keep out squirrels, birds and other critters. The workmanship by MasterShield Atlanta – KTL Home Improvement is excellent!

The MasterShield slides underneath the first row of shingles, but over the shingle starter strip, drip edge flashing and roofing felt. This follows the recommended practice in the GAF Technical Advisory Bulletin for Gutter Covers.

How Well Do MasterShield Gutter Guards Perform?

After 1 month on the house, the MasterShield Gutter Guards have performed exceptionally well during late winter heavy rain storms. The rain water soaks through within the 1st inch of micro-mesh with no overruns. The Big Mouth Valley Blocks easily handles large water flows at the roof valleys.

I talked more on the performance in the following articles:

Update: Will MasterShield Keep the Gutters Clean?

Fast forward over 2 years since I wrote this review and I’m having a gable roof and screened porch built over the wood deck. The gutter is removed and the eave cut back for the new home addition:

The construction crew stacked the gutter and MasterShield gutter guards at the far end of the deck. There’s a thin film of yellow tree pollen and dirt inside the gutter but no leaves, seeds or twigs:

The next photo is a closeup looking inside the gutter. Very admirable performance after 2 years and 3 months of service! The minor amount of shingle gravel and debris in the gutter is due to disassembly and lying open a couple of days. The narrow rubber self-stick gasket on the right edge of the gutter prevents rain water from wicking under the MasterShield gutter guards and streaking the gutter face:
