Gutter Guard | Aluminum Gutter Guard | Micro-Mesh Gutter Guard

A gutter guard is a screen or cover that sits over the gutter so rain gets in and leaves do not. The right one keeps water moving off the roof, away from the fascia and clear of the foundation, and cuts the ladder trips from every month to once or twice a year. This guide explains what the words on a product page mean, how to match a guard to your gutters, and what separates an aluminum guard from a stainless micro-mesh one, so you can choose once and leave it up for years.

Why clogged gutters matter

A gutter full of leaves does not drain. In a storm it overflows at the front, soaking the siding and splashing mud onto the walls, or at the back, where water runs behind the fascia and into the roof edge. In winter the trapped water freezes, and the weight pulls the hangers loose. Over a few seasons the result is rotten fascia boards, a damp basement and a gutter that has to be replaced. A guard keeps the trough empty, so none of that starts.

The second reason is the ladder. Cleaning gutters is the household job most often done from the top rung, in fall, on wet ground. A guard does not remove inspection altogether, but it turns a regular climb into an occasional one, and the cleaning tools on this site do most of the rest from the ground.

Aluminum or stainless steel micro-mesh

Perforated aluminum is the workhorse. It comes in rolls and in snap-in panels, with holes or slots that let water through and hold broad leaves on top. It is light, easy to cut with tin snips, will not rust, and handles the ordinary oak, ash and sycamore leaf fall over most of the country. It is the lower-cost choice for a straight run.

Stainless steel micro-mesh uses a woven screen with openings far smaller than a leaf, bonded to a metal frame. It stops pine needles, fir needles, maple helicopters, shingle grit and the fine debris that slips through perforations and builds up into a mat. It costs more per foot and takes a little longer to fit, but under conifers or maples it is the only type that stays clear. Every product page on this site states the material and the mesh or perforation type, as the manufacturer publishes it.

Width: the number that matters most

Gutter guards are made to a gutter width, and the wrong width either will not seat or leaves a gap at the back. Measure across the top opening of the gutter, from the front lip to the fascia. 5 inch K-style is standard on most American homes. 6 inch is common on larger roofs, newer builds in wet regions and commercial buildings. Some kits also cover 7 inch. Every product page on this site lists the width the guard fits, and if yours measures between sizes, ask us before you order.

Coverage and how much to buy

Walk the house and add up the length of every gutter run, including the short returns at the ends. Add roughly 10 percent for cuts, corners and overlaps. A typical single-story home needs 100 to 150 feet; a larger two-story home can need 200 or more. Rolls on this site come in 50 and 100 foot lengths and panel kits in 48, 52, 104, 120 and 208 foot coverage, so you can buy to your total rather than to a guess. Buying one size up is cheaper than a second delivery.

How guards fix on

Rolls slide under the first course of shingles and either clip to the front lip of the gutter or screw to it. Snap-in and lock-in panels hook over the front lip and tuck under the shingles or rest on the back wall of the gutter. Micro-mesh kits screw to the front lip with the screws supplied, which gives the firmest hold in wind. Whatever the method, the guard should slope slightly toward the front so water does not pool at the back. The fixing method is stated on each product page.

Downspouts need protecting too

The outlet where the gutter meets the downspout is the first place to clog. A downspout strainer, leaf gate or external filter stops leaves and twigs entering the pipe, and a rodent guard keeps mice and squirrels out over winter. A splash block or flexible extension at the bottom moves the water three or four feet away from the foundation. These are inexpensive and take minutes to fit, and we recommend one at every downspout whether or not you guard the gutters.

Tools for the twice-a-year check

Even with guards, plan a look each spring and fall. A telescopic pole with a gutter cleaning head or scoop clears the top of the guard from the ground. A wet and dry vac attachment or a pressure washer wand clears the trough and the downspout outlet. A gutter cleaner removes the black streaks that form on the front face. For the jobs that still need a ladder, a ladder stabilizer rests the ladder on the roof instead of crushing the gutter.

Looking after a gutter guard

Brush or blow leaves off the top after the main fall drop. Check that the front edge still sits flat and the screws or clips are tight after a storm. Clear the downspout outlets. Aluminum and stainless need no coating or paint, and both come in finishes that weather to match the gutter. Treated this way, a metal guard stays up and working for many years.

Your buying checklist

Measure the gutter width: 5 inch or 6 inch. Note what falls on your roof: broad leaves point to aluminum, needles and seeds point to micro-mesh. Add up the run length and add 10 percent. Choose roll or panel by how your gutter is hung and how long the runs are. Add a strainer or filter for every downspout. Then order, knowing you have 14 days to change your mind before you cut.

The short version

Broad leaves, straight runs: aluminum roll or panels. Pine, fir or maple overhead: stainless micro-mesh. Measure the width twice. Buy coverage to your total plus 10 percent. Protect every downspout. Everything we sell lists the specs.
