A new roof is only as good as the tear-off that came before it. Roof demolition (the removal of your old roofing down to the bare deck) is where hidden damage gets found, where code requirements kick in, and where most safety risks live. Done right, it sets up a roof that lasts. Done carelessly, it can mean water damage inside your home, failed inspections, or injuries on the job.
Here’s how a safe, code-compliant tear-off actually works, step by step, and what to look for when you’re comparing contractors.
Step 1: Confirm the Scope and Pull the Permit
Before anyone climbs a ladder, the job needs a permit. In Florida, a re-roof typically requires a permit from your local building department, and fees for a residential re-roof commonly run from roughly $150 to $500.1 The permit application usually includes the scope of work and product approval numbers for the materials going on.
It’s also worth knowing that Florida limits how many layers of roofing can sit on a structure. Generally that’s two total, and if your roof already has two layers, a full tear-off to the deck is required.1 Even when a second layer is technically allowed, tearing off is usually the smarter move, because it’s the only way to see what’s happening underneath.
If you’re in an HOA, check on architectural approval early. That’s separate from county permitting and can add time.
Step 2: Check for Hazards Before Demolition Starts
Older roofs can hide surprises. If your home is decades old, some roofing products and underlayments from earlier eras may contain asbestos, and disturbing them without testing first puts both crews and your family at risk. When there’s any doubt, testing before tear-off is a small cost compared with the cost of a contaminated job site.
This is also the moment to walk the property and note anything that could get damaged or in the way:
- Landscaping, AC units, and pool equipment near the roofline
- Satellite dishes, solar panels, and attic-mounted equipment
- Power lines and service drops close to the eaves
- Driveway and yard areas where the dumpster and debris chute will sit
Step 3: Set Up Fall Protection and Site Safety
Roofing is one of the highest-risk trades in construction, and fall protection isn’t optional. Under OSHA’s residential construction rules, workers exposed to a fall of six feet or more need proper protection, such as guardrails, safety nets, or personal fall arrest systems.
A safe setup includes:
- Harnesses and anchor points installed before crews step on the roof
- Secure ladders extending well past the roofline
- Marked-off ground zones so no one walks under active tear-off areas
- A plan for pets, kids, and vehicles while debris is falling
If a contractor is working on your roof with no visible fall protection, treat it as a red flag about how the rest of the job will be run.
Step 4: Protect Your Property
Tear-off is messy by nature: nails, granules, old felt, and chunks of decking. Good crews plan around that from the start.
- Tarps or plywood over landscaping, patios, and pool cages
- Windows and doors protected from falling debris
- A dumpster or debris trailer positioned as close to the work as possible
- Magnetic sweepers used through the job, not just at the end
That last one matters more than most homeowners realize. Stray nails in a driveway are one of the most common complaints after a re-roof, and it’s entirely preventable.
Step 5: Strip the Old Roofing Down to the Deck
Now the tear-off begins. Crews work in sections, removing shingles, underlayment, flashing, and old fasteners, then getting debris into the dumpster efficiently rather than letting it pile up.
The key discipline here is working in sections you can dry in the same day. Florida weather changes fast, and a stripped roof with no cover is one afternoon storm away from interior water damage. Responsible crews check the forecast, stage their materials, and never open more roof than they can protect before the day ends.
Step 6: Inspect and Repair the Roof Deck
This is the step that makes tear-off worth it. With the old roof gone, the decking is fully exposed and any problems are visible: rot, water staining, soft spots, delamination, or old fastener damage.
Damaged sheathing gets replaced, and in Florida the deck attachment matters just as much as the material on top of it. When an existing roof is removed down to the sheathing, code generally requires the deck to be re-nailed, with 8d ring-shank nails as the standard called out for that work, and homes built before roughly 2002 are the ones most likely to need it.2,3 That re-nailing is one of the biggest hurricane-performance upgrades that happens during a replacement, and it’s invisible once the new roof is on.
Step 7: Dry-In and Inspection
Once the deck is repaired and fastened, the roof gets “dried in” with new underlayment, ideally a sealed, self-adhering secondary water barrier, plus flashing at edges, valleys, and penetrations. Most Florida jurisdictions require a dry-in inspection before the final roof covering goes on, and work can’t move forward until it passes.1
Many building departments also want photos of each roof plane showing the bare, re-nailed decking with the permit number visible, so keep that in mind when you ask a contractor how they document their work.3
Step 8: Cleanup and Final Walkthrough
A good tear-off doesn’t end when the last shingle goes down. Debris gets hauled off, magnets get run across the yard, driveway, and flower beds, and the crew does a walkthrough with you. The dumpster leaving the property is usually part of what the county needs before it will sign off on the final inspection.
From Our Experience: What We Wish More Homeowners Knew
After years of tearing off roofs across Southwest Florida, one pattern comes up again and again: the surprises are almost never on top. A roof can look fine from the driveway, and then the deck comes up and we find soft plywood around a vent stack, old nail heads that never held, or water staining that’s been quietly spreading for years.
We’d much rather tell a homeowner about that on day one of the tear-off than have it show up as a ceiling stain after the new roof is on. It’s also why we walk every homeowner through the exposed deck (photos included) before we cover it back up. Seeing it for yourself makes the repair conversation a lot simpler, and it builds the kind of trust a quote alone never will.
When the Job Goes Beyond a Roof
Most residential tear-offs are straightforward, but occasionally a roofing project turns into something bigger: a structure that’s beyond saving, an addition being removed, or a property that needs full demolition and site cleanup before rebuilding. In the Tampa area, we point homeowners to the team at Mako Services Tampa, who handle demolition, concrete, and remediation work well beyond what a roofing crew is set up for.
