Full Roof Replacement in Jacksonville, FL

A full roof replacement in Jacksonville means tearing off everything down to the decking and installing a new roofing system: new underlayment, new flashing, new drip edge, and new shingles or metal.

When You Need Full Roof Replacement

Not every problem calls for a full replacement. A small leak around a pipe boot or a few missing shingles can often be repaired for a few hundred dollars. But there’s a point where patching stops making sense, and in Jacksonville that point comes earlier than most homeowners expect. Here’s what tells us a home is ready for full replacement:

• Granule loss you can see from the ground. Shingles shed their mineral coating over time. If your gutters collect piles of granules after every rain, the shingles are aging out. In Jacksonville’s sun, asphalt shingles rarely make it past 15 to 18 years even when installed correctly.
• Curling or lifting shingle edges. Heat and humidity work on shingles from both sides. When edges curl upward, water finds its way underneath. Once that starts happening across multiple slopes, replacing individual shingles becomes a losing game.
• Water stains on ceilings or in the attic. By the time water shows up inside the house, it has already passed through the shingles and often the decking. A single stain might be a flashing issue, but stains in multiple rooms usually mean the system is failing.
• Sagging sections you can spot from the street. A roof line that dips between rafters signals decking damage. That’s not a repair situation. That’s a structural problem that requires removing the roof to fix.
• Storm damage from Jacksonville’s summer season. After a tropical system or a bad afternoon thunderstorm, we regularly find lifted shingles, torn flashing, and water intrusion that isn’t visible from the ground. If a storm ripped through Mandarin or Arlington and you’re seeing neighbors get roofs replaced, your roof likely took the same hit.
• Your roof is over 15 years old and you’re planning to sell. Buyers in Jacksonville increasingly ask for roof condition as part of the inspection. An aged roof can stall a sale or knock thousands off the price. Some homeowners choose replacement before listing to avoid that negotiation entirely.

The common thread: none of these conditions improve with time. Jacksonville’s climate doesn’t let a roof coast. Heat expands materials, humidity keeps them damp, and storm season hammers them. If two or more of the signs above are present, a full replacement is usually the honest answer.

Our Full Roof Replacement Process

We run every replacement the same way, using The Garrison Standard. That means the same steps, the same documentation, and the same accountability on every job, whether it’s a 1,200-square-foot ranch off Atlantic Boulevard or a two-story home in Ortega. Here’s how it goes:

1. Inspection and honest assessment. We walk the roof, check the attic, and document what we find. You get a straight answer: repair, partial replacement, or full replacement. We don’t sell a full replacement when a repair is the right call. If it’s a full replacement, we tell you why in plain terms.
2. Written price before any work starts. After the assessment, we put the full scope and the full price on paper. That number covers materials, labor, tear-off, disposal, and everything else. It does not move at the door. No exceptions.
3. Tear-off down to the decking. A proper full replacement removes every layer of old shingles. We don’t layer new shingles over old ones, and we don’t leave damaged decking in place. If we find rotted decking after tear-off, we show you before replacing it and the cost is handled the way it’s spelled out in your written estimate, not sprung on you as a surprise.
4. New underlayment, flashing, and drip edge. The shingles are only the top layer. Underneath, we install new synthetic underlayment which acts as a water barrier, new flashing around chimneys, vents, and valleys which are the joints where leaks start, and new drip edge along the eaves to keep water moving off the roof.
5. New shingles installed to manufacturer spec. We install materials from manufacturer lines including GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. Travis Oakley walks you through the real differences between options: cost per square, wind rating, impact resistance, and how each handles Jacksonville’s climate. You choose with the facts in front of you.
6. Cleanup and final walkthrough. We run a magnetic sweep for nails, clean the yard, and walk the property with you before we leave. You see the finished roof and we answer any questions on the spot. Your 365-Day Done Right Promise is delivered in writing at that walkthrough.

Every technician on your roof is background-checked and arrives in uniform. You know exactly who is on your property, and the office phone is answered by a live person around the clock. No voicemail, no callback queue, no automated system.

Full Roof Replacement Pricing in Jacksonville

Here are honest ranges for full roof replacement in Jacksonville as of 2025. These are ballpark figures for a standard single-family home with moderate pitch and straightforward access:

• Architectural asphalt shingles, 1,200 – 1,800 sq ft home: $8,500 – $13,000
• Architectural asphalt shingles, 1,800 – 2,800 sq ft home: $11,500 – $16,500
• Steep-pitch roof or two-story complexity: add $1,500 – $4,000
• Standing seam metal replacement: $18,000 – $35,000 depending on gauge, panel profile, and home size
• Decking replacement (if existing decking is rotted): $55 – $90 per sheet, used only where needed
• Full tear-off and disposal of existing layers: generally included in the replacement price; we tear off all layers rather than leaving old roof material underneath new shingles

What moves the number: roof size in squares, pitch and number of stories, how many layers we’re tearing off, the shingle line you choose, and whether the decking underneath is sound. Homes in Riverside and Avondale with older decking and tighter access often run higher than newer construction in Bartram Park or Nocatee where the decking is still solid.

FAQs – Full Roof Replacement

How long does a full roof replacement take in Jacksonville?

Most single-family homes in Jacksonville are done in 1 to 3 days from tear-off to final cleanup. Larger homes, steep-pitch roofs, and jobs that require decking replacement can run 4 to 5 days. Weather is a factor, especially during summer storm season, and we’ll tell you up front what the schedule looks like for your specific roof. Call (904) 719-6346 and we’ll give you a timeline with your written estimate.

Is it cheaper to repair or replace a roof in Jacksonville?

Repair is cheaper in the moment, usually $350 to $900 for a typical shingle or flashing fix. But if your roof is past 15 years old in Jacksonville’s climate, repairs become a recurring bill. Homeowners who patch repeatedly often spend more over 2 to 3 years than a full replacement would have cost. We’ll tell you honestly which one makes sense for your roof, and the answer is in writing either way.

What’s the best roofing material for full roof replacement in Jacksonville?

Architectural asphalt shingles are the most common choice for Jacksonville homes, balancing cost, wind rating, and heat performance. Most full replacements we do use architectural shingles rated for 130 mph winds or higher, which meets or exceeds local building code. For homeowners who want higher impact resistance against hail and flying debris, we install options from IKO, Atlas, and Tamko lines that carry Class 3 or Class 4 impact ratings. The honest answer depends on your budget and your specific roof geometry, and we walk you through the trade-offs before you commit.

Do you offer financing or payment plans for full roof replacement in Jacksonville?

We don’t offer in-house financing, but we work with homeowners on scheduling and we’ll never rush a decision. The price you’re quoted is the price you pay, in writing, before any work starts. If that’s the kind of arrangement you can plan around, call (904) 719-6346 for a free estimate and we’ll show you exactly what your roof will cost.

Is it safe for me to be home during a full roof replacement?

Yes, but expect noise and vibration for the duration of the job. Tear-off is loud, and nail guns run most of the day. Keep vehicles clear of the driveway and work areas clear of kids and pets. We use tarps to protect landscaping and run a magnetic sweep for nails before we leave. If you’re home during the job, you’ll see the same discipline: uniformed, background-checked technicians doing the work.

What does the 365-Day Done Right Promise cover on a full roof replacement?

Every full replacement from Brennan Roofing Co Jacksonville is guaranteed in writing for one full year. If something fails within that period and it’s covered under the guarantee, we come back and make it right at no charge. That’s the whole premise of The Garrison Standard: the promise is on paper, it names a specific time period, and it means exactly what it says. Call (904) 719-6346 and we’ll explain the guarantee terms before you sign anything.
