It's independence Day in Wisconsin 🇺🇸
Cookouts 🍔
Brats 🌭
Sparklers 🎆
And an unspoken contest to see who can light up the neighborhood sky. 🧨
But while you're looking up, your roof is taking the brunt of what comes down. And that can mean unexpected damage. Here’s what homeowners and commercial property owners should know about roof fire safety during the July 4th holiday.
Why Your Roof is at Risk from Fireworks
Fireworks are festive, but they’re also unpredictable. Embers, sparks, or whole firework shells can land on rooftops and ignite roofing materials, debris, or gutters. Flat roofs and low-slope roofs are especially vulnerable. Unlike pitched roofs that shed debris, flat surfaces tend to collect it. Including fire hazards.
In Wisconsin, it’s common to see flat or low-slope roofs on homes that have:
Sunrooms
Covered porches
Attached garages or carports
Mid-century modern vibes
Even a small ember sitting on the right patch of dry material can do real damage.
Firework Roof Safety Tips for Homeowners
Before festivities begin, prep your roof. Most firework-related roof damage isn’t caused by a direct hit. Rather, it’s the result of embers landing on flammable debris that’s already there. A little prevention goes a long way.
Clear roof debris before celebrations. Especially around low-slope roof lines and gutters. Think dry leaves, pine needles, even bird nests, all of which can catch fire.
Clean your gutters before the holiday (dry material + fireworks = risk).
Know the wind direction before lighting any fireworks. Be even more cautious in high or inconsistent wind situations.
Keep a safe distance from your own roof when lighting.

Fireworks and Flat Commercial Roofs: What Property Managers Should Know
Commercial roofs don’t get holiday breaks. If you manage a flat-roofed building in southern Wisconsin, especially near neighborhoods, parks, or public event spaces, there’s a good chance it’ll catch some fallout from fireworks on the 4th.
Unlike pitched roofs, flat commercial roofs tend to trap debris. Add synthetic roofing materials, HVAC equipment, and a few stray embers, and you’ve got a recipe for damage that might not be discovered until days later. Especially if the building sits empty over the holiday weekend.
Even a small scorch mark or blistered membrane can lead to leaks or void your warranty down the line.
Firework Roof Safety Tips for Business Owners
Flat commercial roofs are giant landing pads for spent and smoldering fireworks and flammable debris. Don’t give stray fireworks an open runway.
Inspect your flat roof or have a pro do it before the 4th.
Secure rooftop signage or equipment that might attract fireworks or blow embers across the roof.
Talk to neighboring businesses if you suspect firework activity nearby, especially if your building will be closed.
How to Spot Roof Damage After July 4th Fireworks
On July 5th, after the smoke clears, walk the perimeter of your property. Look (and smell) for anything unusual. Not all damage is obvious from the ground. Here’s what to watch for:
Scorch marks or melted areas on shingles or membranes
Charred debris on the roof or in valleys
Smoke stains near attic vents or skylights
Curling shingles or deformed flashing
Gutters clogged with shells, ash, or dry leaves
Minor discolorations
Unfamiliar smells
If you notice anything suspicious, get a free inspection from a roofing pro, rather than climbing up yourself. Rooftop damage may be tricky to spot and risky to inspect alone.
Class A Fire-Rated Shingles vs. Fireworks: What You Need to Know
Many asphalt shingles, including those from CertainTeed, our preferred manufacturer, carry a Class A fire rating, the highest level of fire resistance for roofing materials. That’s good news for your home. But even Class A shingles can’t prevent damage if debris ignites or sits smoldering on the surface. Especially when combined with summer heat and dry conditions. It’s still smart to prepare and inspect.
Are Solar Panels or Solar Roofs at Risk from Fireworks?
If your property has traditional rack-mounted solar panels, it's worth knowing that exposed wiring or junction boxes could, in rare cases, be affected by firework debris. You should never attempt to inspect or touch solar components yourself. When in doubt, call your installer.
Sun Vault Roofing's solar-integrated roofing systems use low-profile shingles with no external racking or wiring on the roof surface, which means fewer points of vulnerability. It’s just one more reason solar roofing can be a smart, safe upgrade.
Is Firework Damage to Your Roof Covered by Insurance?
Most policies cover fire damage, but double-check. If you end up needing to file a claim, having a recent inspection and photos can help.
Don’t Want to Worry? Watch a Public Display Instead
Lighting your own fireworks can be fun, but if you’d rather leave the sparks to the pros (and spare your gutters), here are some local shows worth checking out:
Enjoy the show, support your community, and protect your property all at once.
