South Florida Roof Replacement Guide

Roof replacement in South Florida is governed by the Florida Building Code, which requires HVHZ-rated systems in Miami-Dade and Broward counties — and that means every layer of the assembly must be code-approved, not just the top surface. The job starts with a full tear-off. Every layer of old material comes off, down to the deck. We do not roof over existing shingles or tile. Florida Building Code prohibits it on most re-roof jobs, and for good reason. Trapped moisture under old material causes deck rot that no top coat can fix.

Once the deck is bare, our crew does a board-by-board inspection. Damaged or soft plywood gets replaced before any new material goes down. This step separates a real replacement from a patch job. Skipping it saves a few hundred dollars now but guarantees callbacks and leaks later. Haven's warranty callback rate is under 3% — that number reflects the work that happens before the first new shingle or tile is ever nailed.

After the deck is solid, we install an approved underlayment system. In HVHZ, that usually means a self-adhered modified bitumen base sheet — not the standard felt that works fine in Atlanta or Orlando. The self-adhered sheet bonds directly to the deck and seals around every fastener. It is the last line of defense if the top surface takes a hit in a storm. Then comes the finish layer — shingle roofing, tile roof replacement systems, or metal roofing depending on your budget and home style.

Haven pulls more than 1,500 building permits per year. Every single one represents a project the company touched. We do not do off-permit work — not because it is illegal, but because an unpermitted roof replacement voids your manufacturer warranty, puts your insurance coverage at risk, and can block a future home sale.

In Miami-Dade and Broward, the permit process for a roof replacement also triggers an HVHZ product review. The inspector verifies that the system installed — underlayment, fasteners, top course, and all flashing details — matches the approved NOA assembly. A deviation as small as the wrong fastener spacing can fail an inspection. Our crews train to each approved assembly and carry the NOA documentation on every job site.

Wind mitigation is the financial payoff for doing the job right. Florida's My Safe Florida Home program and most private insurers reward homeowners who have a new, code-compliant roof. After Haven closes your permit, we help you schedule a Uniform Mitigation Verification Inspection (OIR-B1-1802 form). That report goes to your insurer and can lock in lower premiums for the life of the roof. Homeowners near the coast — in areas like Miami Beach, Aventura, and Doral — often see the biggest premium drops because their base rates start higher.

South Florida's climate narrows your material choices in a good way — only proven systems survive here. Architectural shingles from GAF, Owens Corning, and CertainTeed all make HVHZ-rated lines tested to 150+ mph winds. These are not the same shingles sold at a big-box store. They carry Miami-Dade NOA numbers and are tested under TAS 110 (impact) and TAS 100 (wind-driven rain). For a deeper look at shingle options, see our shingle roof replacement page.

Concrete and clay tile are common in historic areas like Coral Gables and older Miami neighborhoods. Tile is heavy — a full concrete tile system runs 9 to 12 pounds per square foot — so the deck and frame must support the load. We assess frame capacity before every tile job. Clay tile costs more but lasts longer and holds color better in UV. Concrete tile offers more profile options at a lower price point. See our tile roof replacement page for a full breakdown.

Metal panels — standing seam in particular — are the fastest-growing choice in South Florida. A standing seam system can hit 180+ mph wind ratings when installed to spec. It is also the lightest option and the best performer against salt air on the coast. Metal roofing costs more up front but carries a 50-year material warranty. For homes in Hialeah, Kendall, and North Miami, where insurance costs are climbing, the premium savings from a metal roof often close the gap within 8 to 10 years.

Not every roof problem calls for a full tear-off. If your system is under 15 years old and the deck is solid, a targeted roof repair may be the right move. Missing shingles after a wind event, a failed pipe boot, or a cracked ridge cap are all repair-level issues. We will tell you honestly which path makes sense. If repair buys you 5 or more good years, we say repair. If the system is past its life or the deck shows widespread rot, we recommend replacement.

The key question is deck condition. A roof replacement that skips a thorough deck inspection is not a replacement — it is a cover-up. Our crew pulls back suspect areas during every estimate so you have a real picture of what is underneath before you sign anything. That transparency is why our warranty callback rate stays under 3% even across 1,200+ projects per year.
