Metal Roof Installation Options in Hollywood
A typical job replaces an existing roof that isn't metal, and the first decision is what has to come off.
Converting a Shingle Roof to Metal
This is the simpler of the two conversions. Asphalt shingles come off quickly, and once they're gone the installer can see the plywood, find the soft spots and renail the deck to the pattern the approved system requires. That last part matters more than the panel you pick, because a metal roof is only as secure as the deck its clips and screws go into.
We'd steer you away from any installer who wants to leave the shingles on to save a day. The code does allow one recover in limited cases, but the deck stays hidden and the approved system has to permit it. On a Hollywood house facing hurricane-force wind, that saving isn't worth much.
See metal roof replacement if the roof you have now is already metal.
Converting a Concrete Tile Roof to Metal
Tile to metal is a bigger job. Concrete tile is heavy and slow to remove, it's set in mortar or foam adhesive that has to be scraped off, and the underlayment beneath it is often old enough to have failed. The code doesn't let a new roof go over tile at all, so a full tear-off is the only route. Expect new flashing throughout as well, since the wall, valley and chimney details made for tile rarely fit a metal panel.
What owners like about this conversion is the weight coming off the framing and the end of cracked tiles after every storm. If your HOA wants a tile look, stone-coated steel pressed into a barrel profile keeps it. See stone-coated steel roofing.
Metal Roofs on New Construction and Additions
On a new house or an addition the roof is designed with the rest of the building, so the deck, the framing and the roof-to-wall connections can be planned around the metal system from the start. Every roofing permit in the hurricane zone includes wind load calculations under Chapter 16 of the Building Code, unless the roof falls below the height and pressure thresholds the applicable protocols allow.
Additions bring one extra job: tying the new roof into the old one. If the existing roof isn't metal, the joint between the two is where leaks start, and the installer should show you on paper how that flashing works.
Choosing the Panel System
Standing seam uses concealed clips, so no screws pass through the flat of the panel; mechanically seamed panels hold better in high wind than snap-lock. 5V crimp is screwed through the face, costs less and needs its fasteners looked after. Stone-coated steel and metal shingles suit complicated roofs and owners who don't want visible seams. Near salt water, the choice between aluminum and coated steel usually decides more than the profile does.

What an HVHZ Metal Roof Installation Includes
Broward County is part of Florida's High-Velocity Hurricane Zone, so an installation here follows Sections 1512 to 1525 of the Florida Building Code rather than the lighter rules used in most of the state. In practice that shapes the job at every layer.
Deck attachment
After tear-off, loose sheathing gets renailed and damaged sheets replaced. The approved system assumes a sound deck of a certain type.Underlayment
Section 1518.9 requires approval for the complete metal system, underlayment and accessories included. The underlayment is chosen from the approval, not from what's on the truck.Panel minimums
Steel panels need a G-90 coating and at least 26 gage; aluminum needs at least 0.025 inch. Many installers offer heavier material, which is worth pricing.Clips and fasteners
Spacing tightens at the eaves, rakes and corners, where wind uplift is highest. The approval sets the pattern.Flashing and trim
Drip edge, valleys, wall flashing and ridge closures in a metal compatible with the panels. Aluminum panels with steel screws is a mistake you pay for later near the Intracoastal.Product approval
A Miami-Dade Notice of Acceptance or a Florida Product Approval listed for HVHZ use, named in your contract by number.Permit and inspections
The code requires a uniform roofing permit application signed by a licensed contractor (or the owner under an owner-builder permit), inspections by the building official during the work, and a final inspection when it's done. Hollywood takes permit applications through its Accela Citizen Access portal.
How Long a Metal Roof Installation Takes
We won't quote a number of days, because it depends on things nobody can see from the driveway. The main ones:
What comes off
One layer of shingles is quick. Concrete tile, with its mortar or adhesive, takes much longer.Deck condition
Rotten sheathing is found only after tear-off, and replacing it adds time.Roof shape
Hips, valleys, dormers and skylights each add cutting and trim.The system
Exposed-fastener 5V goes on faster than mechanically seamed standing seam.Panel lead time
Custom colors and site-formed panels have to be ordered and made.Permit and inspections
The job can't close until the city's inspections pass.Weather
Summer afternoon storms and hurricane season, June through November, stop work on an open roof.
Ask the installer for a start date and a finish window in writing, and ask what happens to the schedule if they find deck damage.
Questions to Ask Metal Roof Installers
Ask these before you sign, and get the answers in the written quote rather than on the phone.
We ask the contractor to put these answers in the written estimate, and you should expect them from anyone you're comparing:
Is your licence active?
Look it up on myfloridalicense.com. A certified roofing contractor holds a statewide licence; a registered one can work only in the area where they qualified.What's the product approval number?
Then look it up yourself and check it's listed for HVHZ use.What metal and what gage?
Steel or aluminum, the exact thickness, and the finish.Which underlayment?
It should match the one named in the approval.Tear-off or recover?
If it's a recover, ask why and ask to see the approval allowing it.Who pulls the permit?
It should be the contractor, under their licence.What's the price per sheet of replaced decking?
That way a surprise under the old roof has a known cost.Who does the work?
The contractor's own crew or a subcontractor, and who you call if there's a problem.
