Here is an after photo of MicroGuard Screen installed. MicroGuard Screen is manufactured from heavy guage 032 aluminimun. This durable leaf protection filter features over 2,000 micro-perforations per foot allowing water in but keeping even the smallest debris out of the gutter. It is available in 3 different configurations; traditional, reverse bend and flat. Quick and easy installation on almost any 5 to 6 inch gutter. The Micro-filter system will not penetrate roof shingles and therefore won’t void roof warranties. Best of all, it is virtually invisible from the curb!
