The comparison is rather striking between these two products. The mesh support for the Gutterglove product is a solid extruded and anodized aluminum structure. We have seen photos of a car driving over a piece of Gutterglove positioned on edge and it did not buckle. We tried it ourselves with the same results. We are not certain what the support material is for the LeafFliter mesh. It is recycled plastic, vinyl or PVC. We have spoken with LeafFilter customers and found discoloration (apparently from UV rays), buckling and warping of the product. Several LeafFilter systems had the stainless steel mesh completely detached.
The difference between the stainless steel mesh for the two systems is that of the alloy. 304 SS vs. 316L SS. The 316L SS mesh, which is specified by Gutterglove, is appreciably more expensive due to its increased chromium and nickel content and the addition of 2-3% molybdenum. The reasons for choosing 316L SS are that of increased corrosion resistance, especially in marine environments. The reason for choosing the low carbon grade of 316 SS is that it maintains its malleability even after the weaving process. 304 SS, the choice of LeafFilter, is more susceptible to pitting and corrosion in marine environments. This can hit home even for those living inland from coastal regions. If icy conditions exist in the winter, streets are heavily sprayed with salt. This can become airborne and is tracked into neighborhoods. Chlorides are present everywhere.
LeafFilter is placed on the gutter in a position horizontal to the ground creating a tray effect. This holds debris and allows it to pile up. Gutterglove is normally placed on a home with a 10 to 15 degree pitch which allows debris to slide off of the micromesh in a downpour or by the wind. We found it refreshing that Gutterglove says there is no totally maintenance free system. They supply each of their customers a telescoping brush with the bristles reversed to knock off any debris that might accumulate on inside corners. We have not found any gutter protection system that has eliminated inside corners buildup.
There are some reverse-curve systems that are nailed or screwed into the roof decking underneath the shingles. This would affect the roof warranty. Neither Gutterglove nor LeafFilter affect roof warranty status. It was mentioned, by some LeafFilter and Gutterglove customers that LeafFilter claims that by placing Gutterglove under the first row of shingles on the drip edge, the roof warranty would become invalid. This is blatantly untrue. We have checked with builders, roofers and insurance companies and they all state that the installation of Gutterglove is perfectly acceptable. Rumors and untruths in our industry give it a bad name. We are trying to set the record straight.
We have no indication that clogging in either the Gutterglove or the LeafFilter systems is a concern. Debris buildup on the LeafFilter system due to its instillation orientation is a negative. Neither system prevents buildup from occurring on an inside corner at the base of a roof valley. Again, we have not found any system that prevents buildup on an inside corner.
Lastly, we address the question concerning dissimilar metals. Gutterglove anodizes the extruded aluminum support. The main reason for this is that they do a considerable number of K-style and half-round copper gutters. They even use brass screws when working with copper gutter systems. This is to eliminate the galvanic reaction between copper and aluminum. It has been verified, by a consulting metallurgist, that any galvanic reaction between 316L SS and aluminum wouldn’t be a concern for well over 50 years.
