Screens are the most inexpensive option for gutter guards available today. These guards are either made up of plastic or wire and are installed to block the leaves from entering the gutter. You do not even require any tool to install this. But one of the major drawbacks of these guards is that they can get damaged and detached very easily, leaving the gutter system uncovered once again.
A Micro Mesh gutter guard works in a similar way to a screen. But the difference is that these guards are much more durable than the screen as they are made up of plastic and stainless steel. Micro mesh does not just block leaves but also fine grains of sand from entering the gutter system. Though these are permanent solutions, regular cleaning through scrubbing is required to remove the fine debris that gets attached to the hole of the mesh.
A reverse curve is much more efficient than a micro-mesh or a screen. It is manufactured of lightweight metal and can be also used in houses that are surrounded by yards of leafy trees. You need to install a reverse curve in a proper manner, otherwise, you will face the problem of water running over the edge and pests entering through the gap. Also, a reverse curve is more expensive than a screen and a micro mesh.
These are guards that can be easily installed inside the gutter system and are mostly inexpensive. This is the reason why many homeowners prefer to get this option as a DIY method. But it has been found that sometimes, leaves build up behind the bristles that are projecting from the guard. Hence, most experts do not consider using and suggesting this gutter guard for even residential purposes.
This particular gutter guard is made up of polyurethane and you need to insert this foam guard inside the gutter. This guard is one of the most efficient options because the foam just lets water enter the gutter, leaving other debris out. But the foam quality may start getting deteriorating much faster in areas such as Portland where the amount of rainfall is much higher. So, either you have to replace the foam guard every year or you may have to consider some other options.
