When to Replace Your Roof Before Installing Solar
Removing and reinstalling a solar array to fix a roof underneath costs thousands. Here is how to decide before you sign a solar contract.

Should I Replace My Roof Before Installing Solar Panels?
If your roof has fewer than 10 years of expected life left, replace it first. A remove-and-reset to service a roof under an existing array typically costs $3,000 to $6,000, so it is cheaper to re-roof before panels go up than after. Coastal Energy installs metal and tile roofs only.
- Decision threshold
- 10 years
- Remaining roof life before it's worth re-roofing first
- Remove and reset cost
- $3,000 - $6,000
- To pull panels, repair roof, reinstall array
- Metal roof lifespan
- 40 - 60 years
- Standing seam or metal shake, Florida climate
- Tile roof lifespan
- 30 - 50 years
- Concrete or clay tile, underlayment often fails first

The Math Behind Roof-First Sequencing
A solar array is designed to last 25 years or more. Very few Florida roofs installed more than 10 to 12 years ago will still be watertight for another 25 years. If you install solar on a roof that needs replacement in year 6 or 8, you will pay a licensed crew to remove the panels, replace the roofing underneath, and reinstall the array, which runs $3,000 to $6,000 depending on system size and roof pitch.
That cost is avoidable. Because Coastal Energy holds both a roofing license (CCC1335978) and an electrical license (EC13013993), we evaluate roof condition as part of every solar site survey, not as an afterthought, and can quote a re-roof and solar install as one coordinated project when it makes sense.
Our position
Why We Only Install Metal and Tile Roofs
Coastal Energy installs metal and tile roofs only. We do not install new shingle roofs, and we do not price shingle replacement. Metal outlasts shingle in Florida's sun, salt air and hurricane wind by a wide margin, and a shingle roof reliably fails long before a well-built solar array does. If we re-roof a home before installing solar, that roof goes on as metal or tile, sized to outlast the panel warranty rather than needing a second replacement mid-array.
Metal runs $12 per square foot (a square is 100 sq ft) for a standard mil finish, plus $1.50 per square foot if you want a Kynar color finish. On a typical 2,000 sq ft roof, that works out to roughly $24,000 to $27,000 installed. Tile is quoted per project, since tile work is highly variable by profile, pitch and existing structure. Roofing work carries a separate 5 year workmanship warranty, while eligible new solar installations include 30 year Solar Insure parts and labor protection.
Decision table
Roof Age and Material vs. Solar Readiness
Use your roof's age and material as a starting point, then confirm with a physical inspection.
| Roof type | Typical lifespan | Re-roof before solar if age is | Notes |
|---|---|---|---|
| Concrete or clay tile | 30 - 50 years | 20+ years old | Tiles often outlast the underlayment beneath them, which fails around year 20 - 25 |
| Metal standing seam or metal shake | 40 - 60 years | Rarely needs replacement first | Panels can often mount with clamps that do not penetrate the roof |
| Existing asphalt shingle | 15 - 25 years | 10+ years old, or before solar goes on | We replace aging shingle roofs with metal or tile before solar; we do not install new shingle roofs |
Ranges are general industry figures for Florida's heat and UV exposure. Your roof's actual condition matters more than age alone.
What we check
What a Roof Inspection for Solar Readiness Actually Covers
Every Coastal Energy site survey includes a roof condition assessment before we finalize a solar design. We are looking at more than just visible wear, because the goal is a roof that outlasts the panel warranty without interruption.
If the inspection turns up problems on an existing shingle roof, we present metal or tile replacement options rather than patching a material we do not install new. If the existing roof is already metal or tile and sound, a partial repair to the specific planes where panels will mount is often enough.
- Cracked or slipped tiles and underlayment condition on tile roofs
- Seam, fastener and coating condition on metal roofs
- Flashing and penetration points around vents, chimneys and skylights
- Decking condition, since soft or rotted decking must be replaced regardless of roof age
- Existing leaks or water staining in the attic
Process
How a Combined Re-Roof and Solar Project Runs
01
Roof and Solar Site Survey Together
One visit evaluates roof condition, attic framing, electrical panel and solar production potential, so you get one honest recommendation.
02
Re-Roof Scope and Solar Design Finalized
We choose metal or tile, color and finish to pair with your planned array, and finalize panel layout for the new roof.
03
Roofing Installed First
Our roofing division tears off and replaces the roof under license CCC1335978, including new underlayment and flashing at every future panel attachment point.
04
Solar Installed on the New Roof
Panels go on a roof with a fresh warranty clock, avoiding any future remove-and-reset cost for the life of the array.
05
Permitting and Inspection for Both Scopes
Roofing permit and solar/electrical permit are coordinated through the same building department timeline where possible.
Cost comparison
Sequencing Cost: Roof First vs. Roof Later
A simplified comparison for a mid-size Florida home replacing an aging roof with metal, on a 2,000 sq ft roof.
| Approach | Roof cost | Solar cost | Remove and reset | Total |
|---|---|---|---|---|
| Re-roof (metal), then solar | $24,000 - $27,000 | $25,000 - $27,000 | $0 | $49,000 - $54,000 |
| Solar now, re-roof (metal) in 6 years | $24,000 - $27,000 (future dollars) | $25,000 - $27,000 | $3,000 - $6,000 | $52,000 - $60,000 |
Figures are illustrative Florida ranges, not a quote. Metal pricing is $12 per square foot plus $1.50 per square foot for a Kynar finish. Tile is quoted per project because it varies too much to estimate here.
Exceptions
When It Is Fine to Install Solar Without Re-Roofing First
Not every home needs a new roof before solar. Metal standing seam roofs often accept clamp-mounted racking that does not penetrate the roofing material at all, which sidesteps most of the remove-and-reset concern. A tile roof installed within the last 8 to 10 years, in good visible condition with no leak history, is also generally a reasonable candidate for solar as-is.
The honest answer depends on a physical inspection, not a rule of thumb alone. That is why we build roof evaluation into every solar proposal rather than charging separately for it.
