The type of guards is what matters most, which leads us to the next topic of what’s available. The industry standard right now is Alluminum guards, do not settle for less. There are cheaper options out there like foam or plastic mesh, but never once have we visited a customers property with these products and thought man, what a great investment. 9/10 times, when customers call us with blockage issues or a general eaves clean while having these products installed, you tend to find that these were the reasons why the customer was having issues in the first place. But to emphasize, this is here in Canada this may work for you elsewhere if you are in rural areas. But at that point, take a second thought on investing into these where it might not even be needed at all.
