Your roof will give you clues when it’s time to change, like a few missing shingles here or a rising energy bill there. You need to pay attention to these seven signs to invest in a new roof at the right time.
We’ll explain what each one means and how to tell whether you’re looking at a repair or a full roof replacement.
How Long Does a Roof Last in Florida?
Manufacturers will tell you 25 to 30 years. In Florida, that number doesn’t hold up. Between the UV intensity, the humidity, and the summer storm cycle we get on the Space Coast, asphalt shingle roofs in this state typically last 15 to 20 years.
That gap is the difference between planning ahead and finding out the hard way, usually when your insurance company sends a non-renewal letter (more on that below). If your roof was installed before 2011, it’s worth getting it looked at, even if it “looks fine” from the driveway.
The 7 Signs You Need a New Roof
1. Your Roof Is 15-20+ Years Old
This is the biggest red flag, and it’s the one homeowners argue with most, because the roof usually still looks fine from the ground, even when the wood underneath is already rotting. Years of Florida sun and heat wear the material down on their own – you don’t need a bad storm for that.
If your roof is close to 20 years old, get someone out to look at it now, before it starts leaking. A lot of Space Coast roofs put on after the big hurricane years (2004-2005, 2017, 2022) are hitting that 15-20-year mark right now.
2. Curling, Cracking, or Missing Shingles
Curling edges, cracks down the middle, missing shingles altogether – that’s your roof telling you the material is done. It happens because heat and moisture cycling make shingles lose their flexibility, and once that happens, wind gets underneath them and tears them loose.
You don’t need a named hurricane for this either; regular tropical-storm-force winds do it too. A handful of missing shingles after one storm is usually just a repair. But if you’re seeing curling across large sections or shingles coming off in moderate wind, that’s the whole roof system failing, not one bad spot.
3. Granule Loss in Your Gutters
Those coarse, sandy granules on asphalt shingles are the roof’s UV shield, not decoration. When they’re piling up in your gutters or at the base of your downspouts, that shield is wearing off – and because Florida gets hit with more intense UV than most of the country, this happens faster here than up north.
Some granule loss in year one on a new roof is normal. On a roof over 10 years old, heavy buildup means the asphalt underneath is exposed and breaking down, and a repair won’t fix that.
4. Daylight Through the Roof Boards
Head into your attic on a sunny afternoon, kill the lights, and look up. If you can see daylight coming through the boards, water is already finding its way in, whether or not you’ve spotted a stain on the ceiling yet. This is structural.
Call a roofer right away instead of waiting for a leak to confirm what you already saw.
5. Sagging or Soft Roof Deck
Stand across the street and look at your roofline – it should be straight. Dips, waves, or soft spots mean the plywood or OSB decking underneath has already rotted from trapped moisture, or in worse cases, the rafters themselves are compromised. This isn’t something you patch. It needs attention now, and it can be a genuine safety issue heading into hurricane season.
6. Widespread Moss, Algae, or Tar Streaking
Dark streaks or green/blue growth on shingles are common, given Florida’s humidity, and on their own they’re mostly cosmetic – algae and moss just thrive in the moisture our climate provides, especially on shaded or north-facing sections of roof.
Light staining is a maintenance issue, nothing more. But once moss gets thick and widespread, it traps moisture directly against the shingle surface and speeds up decay underneath. At that point, it’s not just an eyesore; it’s actively contributing to the roof failing.
7. Rising Energy Bills
This is the weakest sign on the list, and worth saying plainly: energy bills climb for plenty of reasons that have nothing to do with your roof – an aging AC unit, poor attic insulation, a door someone keeps leaving open. A compromised roof creates gaps in ventilation and insulation, making your HVAC work harder.
But treat it as supporting evidence, not proof. If you’ve ruled out the mechanical stuff and your cooling bills are still climbing, stack it on top of any of the other six signs above – that combination is what means something.
The Florida-Specific Sign Nobody Talks About: Your Insurance Won’t Renew
If you own a home in Florida, there’s an eighth warning sign that matters just as much as roof damage, and it has nothing to do with how your roof looks.
Citizens Property Insurance and most private Florida insurers are now refusing to renew policies – or demanding a full roof replacement – on roofs 15 to 20 years old, no matter what condition they’re in. This isn’t just happening in coastal high-risk zones. It’s happening right now across the Space Coast.
Here’s what that usually looks like:
- 4-Point Inspections: If your roof is over 15 years old, most carriers will require one of these before renewing or writing a new policy. It checks your roof, electrical, plumbing, and HVAC – and a bad roof is the number one reason people get denied.
- Wind Mitigation Requirements: Live in a High-Velocity Hurricane Zone, or just want a lower premium? Your roof’s age and how it was installed will directly affect your rate.
- Non-Renewal Letters: Sometimes the first sign your roof needs work isn’t a leak – it’s a letter saying your policy is getting canceled unless you fix it.
If you’ve already gotten a 4-point inspection request or a non-renewal notice, don’t sit on it. Roofers get slammed during peak season, and that can push your timeline back further than you’d expect.

What to Do If You’re Seeing These Signs
- Document what you’re seeing. Photos and dates matter, especially for insurance claims.
- Pull your records. Roof age, past repairs, and any warranty paperwork will speed up your inspection.
- Get a professional inspection. A licensed roofing contractor who will physically get on the roof.
- Get a written estimate before agreeing to anything, and don’t be afraid to compare it against a second licensed opinion.
If you’re in Melbourne, Palm Bay, or anywhere along the Space Coast, Florida Roofing & Renovations Inc. offers free inspections for exactly this reason, so you know whether you’re looking at a repair or a replacement before you spend a dollar.

Frequently Asked Questions
How Much Does a Roof Replacement Cost in Florida?
Depends on your roof’s size, pitch, and material. For a typical single-family home, asphalt shingles usually run $8,000 to $15,000. Metal will cost more upfront. The best way to get a real number is a written estimate for your specific house.
Will Homeowners’ Insurance Cover My Roof Replacement?
It depends on the cause. Storm, wind, or hail damage is typically covered minus your deductible. Wear from age is not. That’s on the homeowner, which is part of why insurers are pushing proactive replacement on older roofs.
How Do I Know If It’s Storm Damage or Normal Wear?
Damage from storms occurs quickly and is localized – missing tiles as a result of wind, and hail dents appearing out of nowhere. Ordinary wear occurs over time and involves all the elements of the roof at once: tile curving, loss of granules, and fade.
What’s the Best Time of Year to Replace a Roof in Florida?
Late fall through spring, before hurricane season starts in June. But if your roof is already leaking or failing, don’t wait for good timing – a roof that fails in a summer storm costs far more than replacing it now.
How Long Does a Roof Replacement Take?
One to three days for most homes in Melbourne and Palm Bay. It depends on the roof’s size, pitch, and whether the decking needs replacing.
What Does a Bad Roof Look Like?
From outside: sagging spots, curling or missing shingles, dark streaks or moss where moisture’s collecting. Inside: water stains on the ceiling, flaking paint, daylight through the attic boards. One of these might mean a repair. A few at once means replacement.
What Roofing Material Lasts Longest in Florida’s Climate?
If you are building a house or rebuilding a roof in Florida, then metal is the optimal option. Such a material will withstand our intense sun and hurricanes for decades. Metal roofing will serve 40+ years easily, much longer than usual asphalt tiles. In particular, on the Gulf Coast of Florida, it does not have equal competitors.
