Gutter guards are worth fitting on most South Florida properties with trees near the roof. They are not the maintenance-free promise some of the advertising makes them, and a company that tells you that you will never go up a ladder again is selling you something.
Here is the honest version: what they do, what they do not, and which types are worth the money here.
What they do
- Keep leaves, twigs and seed pods out of the trough. This is the main job and a decent guard does it well.
- Stretch the interval between cleanings. A property that needed clearing three times a year typically goes to once.
- Stop the trough from becoming a nursery. Mosquitoes breed in standing water held by debris. Less debris, less standing water.
- Keep birds and rodents out. An open gutter packed with dry material is a nesting site. A screened one is not.
- Reduce the weight the hangers carry. Wet, packed debris is heavy, and that weight is what pulls runs out of line.
What they do not
- They do not eliminate maintenance. Fine material still gets through a mesh, and whatever lands on top of a guard has to be brushed off or it mats and sheds water over the edge.
- They do not fix a gutter that is the wrong size. If the run overflows because it is undersized or short of outlets, a guard changes nothing — and a badly chosen one makes it worse by narrowing the opening.
- They do not fix fall. Standing water from a sagging run stays standing under a guard, and you can no longer see it.
- They do not stop pollen, shingle grit or the fine black sediment that builds into a sludge in the bottom of the trough.
- They do not survive being walked on. Anyone who puts a ladder against a guarded gutter without knowing what they are doing will deform it.
The types, and which work here
Aluminium or stainless mesh. A perforated or woven screen over the trough. Good balance of cost and performance, and the type we fit most often. Stainless outlasts aluminium near salt air, which matters on the coast.
Micro-mesh. A much finer screen, usually stainless on a frame. It stops the small material the standard mesh passes, and it is the best option under pines or anything that drops needles. It costs more and it needs the top brushed off occasionally, because fine mesh is exactly what pollen and dust mat onto.
Reverse curve, or surface tension. A solid cover with a lip, relying on water clinging around the curve and into a slot while debris falls past. It works in moderate rain. In a two-inch-an-hour storm, a volume of water that is moving fast does not cling to anything — it carries straight over the lip and onto the ground. We do not recommend them here for that reason.
Foam inserts. A block of foam filling the trough. Cheap, easy, and they degrade in UV, hold moisture against the metal, and eventually grow things. They are a short-term fix sold as a permanent one.
Brush inserts. A large bottle brush laid in the gutter. Debris collects in the bristles rather than in the trough, which means you still have to pull the brush out to clean it. Marginally better than nothing.
The South Florida specifics
Royal palms shed fronds and seed pods that no guard will handle gracefully — a frond lands on top and sits there. If you have palms over the roof, plan on brushing the guards rather than clearing the gutters, and fit 3×4 downspouts so that anything which does get through keeps moving.
Near the ocean, salt air eats cheap aluminium screen and the steel fasteners holding it. Stainless costs more at fitting and less over ten years.
And whatever you fit, it has to be installed without lifting the roof edge. Guards that slide up under the first course of shingles or tiles can break the water seal at the eave, which trades a gutter problem for a roof problem. We fit to the gutter, not to the roof.
Is it worth it
Run the arithmetic on your own property. If you are paying for three clearings a year, guards typically pay for themselves in two to four years and remove the part of the job you dislike most — the ladder.
If you have no trees near the roof and you clear the gutters once a year without much trouble, you probably do not need them, and we will tell you that.
