New Roof and Solar Together in St. Petersburg: Cost, Permits

Replacing the roof and adding solar together in St. Petersburg costs $1.85 per watt installed for the solar through Fused Solar and Roofing, so a 20-panel, 8.8 kW system of JA Solar 440W panels is $16,280, plus the roof, which is quoted after measuring, and the two can be financed as one project over thirty years through Climate First Bank when the roof is no more than 45 percent of the total. Doing both at once means the panels go onto brand-new decking, underlayment, and flashing the same week the roof goes on, and the homeowner never pays to take them off for a re-roof later. St. Petersburg's 1920s bungalows and 1950s block ranches are on their third or fourth roof, and the bundle is how a homeowner gets the next one and the solar on it without paying for a detach and reinstall later. Fused Solar and Roofing is a licensed roofing (CCC1331058), electrical (EC13014750), and building contractor (CBC1252064), all three in-house.

1. Why St. Petersburg homeowners do the roof and the solar together

St. Petersburg has some of the oldest housing in Pinellas County, and many of its roofs were replaced in the wave after the 2004 storm season, which puts them at twenty years now. The city's flat and low-slope sections on older homes, and the salt air in the bayfront and beach-adjacent neighborhoods, wear a roof faster than inland, so a homeowner asking about solar is usually told the roof should go first, and the bundle is how both get done on one permit set and one loan.

A solar array lasts twenty-five years. A shingle roof in Florida lasts fifteen to twenty. Putting new panels on a roof with five or ten years left means a full detach and reinstall, with its own permit, partway through the system's life. Replacing the roof first, or at the same time, removes that cost and puts the attachments into new wood and new flashing.

🔑 Key Takeaway: In St. Petersburg the roof-and-solar question is mostly a roof-age question; if the roof is past fifteen years, the bundle is almost always the cheaper path over the life of the system.

2. What the bundle costs in St. Petersburg

The solar side is priced at a flat $1.85 per watt installed. A 20-panel, 8.8 kW system of JA Solar 440W panels is $16,280; a 26-panel, 11.44 kW system is $21,164. A Tesla Powerwall 3 adds $12,500. Two-story homes, steep pitches, and tile roofs carry priced adders shown as their own lines on the solar side; the roof price already accounts for height and pitch.

The roof is quoted after Fused measures it, because shingle, tile, and metal are different prices and so are the number of roof planes, the pitch, and the condition of the decking. Every Fused roofing job includes two sheets of replacement plywood at no charge, with additional decking billed only beyond that allowance. Flat or low-slope sections, which many older St. Petersburg homes have on a Florida room or a lanai, get a TPO membrane rather than metal.

💡 Pro Tip: Ask for the roof and the solar on one proposal with the two prices shown separately. The combined number is what the bank finances, but the split is what tells you whether the roof is within the 45 percent limit.

3. The roof Fused installs

Fused installs the GAF Timberline HDZ shingle system and, as a GAF Certified Plus contractor, registers an enhanced GAF warranty on it; every roof-and-solar bundle includes the GAF System Plus warranty so the roof coverage outlasts the thirty-year loan. Under the shingle, Fused installs a self-adhered leak barrier over the entire deck, not just the eaves and valleys, which is the detail that keeps a Florida roof dry when wind-driven rain gets under a shingle.

Tile and metal roofs are also installed, and Fused does a lot of tile work. On a tile re-roof the solar mounts are set to the deck under lifted tiles with flashed replacement tiles; on a standing-seam metal roof the mounts clamp to the seams with no penetration at all.

The homeowner's insurance adjuster can meet Fused at the roof when a claim is part of the project.

4. How the solar goes onto the new roof

Every panel is attached with K2 Systems hurricane-rated flashed mounts, lag-bolted into the rafters or trusses and flashed under the new shingle course so water sheds over the mount. Because the roofing crew and the solar crew work from one plan, the mounts go in the week the roof is finished, through new decking and the new leak barrier. Every solar roof penetration carries Fused's written 25-year no-leak guarantee, backed by the same company that holds the roofing license and installed the roof.

That is the practical difference between a bundle from one licensed company and a roofer plus a solar firm: there is no argument later about whose penetration leaked, because the same license covers both.

5. Financing the bundle, and when not to

A roof bundled with solar can be financed as one project over thirty years through Climate First Bank, with the bank's rule that the roof portion is no more than 45 percent of the total project cost. A roof on its own is financed through a separate fifteen-year program. Fused does not offer solar leases, because a lease makes a home harder to sell and its payments rise every year. Bank fees are set by the bank and depend on the homeowner's credit, so Fused does not advertise them; the bank discloses them with the approval.

Some homes should not bundle. A roof with fifteen years of life left does not need replacing, and Fused will say so and quote the solar alone. A roof where the solar portion is small enough that the roof would exceed 45 percent of the total is financed differently, and Fused shows both structures before the homeowner picks. Specific questions about a loan belong with the bank or the homeowner's own financial advisor.

⚠️ Warning: A bundle quote that shows one combined price with no roof-and-solar split cannot be checked against the bank's 45 percent rule, and it hides which part of the job is priced high. Ask for the two numbers.

6. Permits in St. Petersburg: two scopes, two permits

Inside the city, both permits come from St. Petersburg Construction Services at One 4th Street North, which runs applications and inspections through Click2Gov with plan review in ePlan. The solar side has its own Solar Permit Submittal Checklist: sealed attachment, flashing and structural details for the wind zone, equipment spec sheets, and a roof layout, and the city requires the permit to be pulled by a solar or electrical licensee. Plan review comments have to be answered within ten days or the application is denied, so Fused watches the ePlan queue daily. The roofing permit is separate, pulled under Fused's roofing license, and Click2Gov will not accept an application from a contractor whose license is not verified with the city, which Fused's is. A recorded Notice of Commencement is required on projects over $5,000.

7. Timeline and the utility

From signed contract to a producing system, a roof-and-solar bundle runs six to eight weeks. Permitting takes two to three weeks for both permits together. The roof goes on in one to two days and passes its inspection; the solar goes on in one to two days the same week or the next; the solar inspection follows; then the utility's approval and meter. The homeowner sees crews on site for about a week in total.

Duke Energy Florida serves St. Petersburg. After the solar inspection passes, Fused files the interconnection application with Duke, and the net meter is set after Duke approves it; the system stays off until the meter is in, and the timeline for that step is set by Duke rather than the installer.

Frequently Asked Questions

How much does a new roof and solar cost together in St. Petersburg?
The solar is $1.85 per watt installed through Fused Solar and Roofing, so a 20-panel, 8.8 kW system is $16,280 and a 26-panel, 11.44 kW system is $21,164. The roof is quoted after measuring because material, planes, pitch, and decking condition set the price. The two appear as separate lines on one proposal.

Can I finance the roof and the solar together?
Yes, over thirty years through Climate First Bank, as long as the roof portion is no more than 45 percent of the total project cost. A roof alone is financed through a separate fifteen-year program. Fused does not offer leases, and bank fees are set by the bank based on credit.

Do I need two permits for a roof and solar in St. Petersburg?
Yes. St. Petersburg Construction Services issues both through Click2Gov with ePlan review; the solar permit follows the city's Solar Permit Submittal Checklist and must be pulled by a solar or electrical licensee. Fused pulls both, the roof under CCC1331058 and the solar under EC13014750, and answers plan comments inside the city's ten-day window.

What roof does Fused install with solar?
The GAF Timberline HDZ shingle system over a self-adhered leak barrier covering the entire deck, with the GAF System Plus warranty included in every bundle; tile and standing-seam metal are also installed. Two sheets of replacement plywood are included on every roofing job.

How long does a roof-and-solar bundle take in St. Petersburg?
Six to eight weeks from signed contract to a producing system. The roof goes on in one to two days and the solar in one to two days the same week or the next; the rest is permitting, two inspections, and the utility's approval.

Should I bundle if my roof is only ten years old?
Usually not. A roof with fifteen years of life left does not need replacing, and Fused will quote the solar alone. The bundle makes sense when the roof is past fifteen years, so the array and the roof start their lives together and no detach and reinstall is needed later.
