Why install MasterShield gutter guards over LeafGuard gutters

We know when you do your research - like we did - you'll come to the same conclusion: MasterShield is the only leafless gutter product on the market that is proven to work in the Pacific Northwest.

We went head-to-head with LeafGuard, one of the "best-selling” gutter protection systems on the market today. The results were shocking. Just see the pictures for yourself. These photos are were taken of real situations in which we installed LeafGuard gutters in Seattle.

These photos explain why LeafGuard doesn't give you a 100% Money Back Guarantee like MasterShield. The only "guarantee" they offer is to come back and "clean your gutters."

Issues with temperature and reverse curve gutter guards

Many of the most popular gutter guard products are made of vinyl. A major selling point is that they are better for the environment. While this might be true, vinyl is also prone to warping (and even melting) in direct sunlight.

Weather events like hail and extreme temperature differences, which are common here in the Pacific Northwest, wreak havoc on vinyl. Temperature changes cause expansion (when it’s hot or in direct sunlight) and contraction (at night and in the cold). This constant expansion and contraction ruins the plastic. Understand that these types of gutters and gutter protection will warp. A discrepancy as little as a 1/8 of an inch can cause damage to your home.

What about metal reverse curve gutters?

Reverse curve technology has been around since the 1900s. According to the U.S. Patent Office, George Cassen first patented this type of technology on June 23, 1908. Since then, more than 100 companies - including LeafGuard and LeafFilter - have modified this technology to make it "unique" to their company. The reality is that all of these brands are so similar that the only significant difference is the way each company markets their product. 

The science behind reverse curve gutters and why it's a problem

Reverse curve gutters work exceptionally well, but only in a controlled environment. These systems work on water tension and the capillary action of liquids. This is fine, as long as you don't break the surface tension. This only happens when you have a controlled (set amount) of water flowing into the gutter.

Here in the Seattle area, we get vastly different rates of rainfall. One day it's a drizzle; the next day it's a torrential downpour. This causes issues with reverse curve gutters, like LeafGuard. Increased rainfall means increased water flow, causing a break in surface tension and the water to simply pour over the gutters. Less rainfall means insufficient water flow to adequately remove the debris and worse, it causes the debris to just get hung up in the opening and block any and all water from passing inside. It's important to understand that other gutter guard companies do not consider water running over the system as a clog.



If you are considering LeafGuard or another gutter guard company that sells a similar product, ask them what would happen if you increased or decreased the rate of water. Then, ask them to show you using their demo product.

We will bet that one of two things will happen (or both):

A. They will invent an excuse as to why they can't do that with their product demo.

B. They will promise to come out and "clean" or "fix" your gutters if there is ever a problem.
