Living in South Florida means preparing your home for hurricane season — every year. Most homeowners focus on windows, doors, and roof. But one critical system gets overlooked until it's too late: your gutters.
A failed gutter system during a hurricane isn't a leak problem. It's a wall-water-intrusion problem, a fascia-rot problem, and a foundation-erosion problem. Proper preparation now turns a $4,000 water-damage repair into a $0 non-event.
Here's the contractor-written checklist we run on our own homes before June 1st.
The 8-point pre-hurricane checklist
1. Full clean-out
Every downspout, every elbow, every outlet. Palm thatch is the biggest culprit in Miami — it accumulates fast and forms a near-impermeable mat at downspout openings. Clean by hand, then flush with a hose at full pressure. If water doesn't run clean through every outlet, something is still clogged.
2. Tighten or replace hangers
Walk every linear foot. Push gently on the gutter — any flex means a loose or rusted hanger. Modern hidden hangers should be every 24 inches. If you've got spike-and-ferrule hangers from 2005, this is the year to upgrade.
3. Reseal every joint
Every corner, every outlet, every end cap. Use a high-quality polyurethane sealant rated for UV and constant moisture. Silicone caulk is not good enough — it dries out and cracks in South Florida sun.
4. Check pitch
Every run should slope toward its downspout — about ¼ inch per 10 feet. Standing water in a gutter is a sign of bad pitch (or a sagging hanger), and it'll dump straight over the lip in a storm.
5. Inspect the fascia
Look for soft spots, peeling paint, daylight visible between the fascia and the gutter. Rotted fascia can't hold a gutter under hurricane load. If you find rot, fix it before the storm.
6. Confirm downspout count
Rule of thumb: one downspout per 30–40 linear feet of roofline, plus one at every termination. If you've got a 200-foot home with only 3 downspouts, you're guaranteed to overflow in any major storm.
7. Extend downspouts away from the foundation
Downspouts should discharge at least 4–6 feet from your foundation, into a splash block, drainage extension, or buried PVC. In a hurricane, foundation water is the slow-motion damage you don't see until 6 months later.
8. Document everything (photos)
Before the storm, photograph every gutter and downspout. If you do need to file an insurance claim, you'll have a baseline showing what they looked like before.
What to actually do during the storm
Counterintuitive answer: nothing. Once the storm is within 24 hours, stay off the roof. Gutters are designed to fail safely — losing a gutter is acceptable; falling off your roof is not.
What to check after the storm
- Walk every gutter run from the ground, looking for: separated joints, dented sections, missing end caps, detached downspouts
- Look at the soil under every downspout for major erosion
- Check the fascia and soffit for water staining
- If anything looks off, call a professional before the next storm rolls in (which, in South Florida, can be days)
When to upgrade vs. when to repair
If your current gutter system is:
- 10+ years old and made of .027 builder-grade aluminum → consider full replacement in heavy-gauge .032 seamless
- Sectional with sealed joints → strong replacement candidate (see Seamless vs Sectional)
- Built before Miami-Dade Hurricane Code revisions (pre-2007) → audit the hangers; many won't meet current wind-load specs
We do free pre-hurricane inspections every May. If you want one, call (786) 646-7684 or request online.
The Del Toro hurricane standard
Every install we do is built to ride out Category 3+ wind:
- .032 heavy-gauge aluminum
- Hidden hangers every 24 inches
- Polyurethane sealant on every joint
- Pitch verified with a digital level
- Downspouts secured with stainless straps every 6 feet
- Written workmanship warranty
If you're heading into hurricane season unsure about your gutters, get them looked at before June. The peace of mind is worth the call.
