Anatomy of a South Florida High-Velocity Metal Roof

A metal roof is an integrated building envelope defense system. Every layer from the structural framing to the custom-seamed ridge caps must perform under extreme atmospheric pressure.

LAYER 01 / STRUCTURAL SUB-DECK

CDX Structural Plywood & 8d Ring-Shanks

All rotted wood is excised and replaced with minimum 5/8-inch 4-ply CDX plywood. Re-nailed with 8d ring-shank fasteners at 6-inch perimeter centers and 6-inch field centers to meet HVHZ 175+ MPH uplift schedules.

LAYER 02 / SECONDARY WATER BARRIER

Polyglass Polystick XFR High-Temp SWR

Direct-to-deck self-adhering modified bitumen underlayment with a high-temperature rating of 265°F. Prevents thermal degradation beneath metal panels and guarantees 100% watertight protection even during Cat-5 hurricane wind-driven rain.

LAYER 03 / EXPANSION FASTENERS

Concealed Stainless Steel Thermal Clips

Zero exposed screw penetrations on the roof face. Panels are secured using concealed stainless steel floating clips that allow seamless thermal expansion and contraction during intense South Florida daily sun-to-rain thermal shocks.

LAYER 04 / SURFACE PANELS

24-Ga Galvalume or .032" Marine Aluminum

Continuous rolls custom-fabricated on our computerized roll-former to the exact millimeter dimensions of your eaves and ridges, eliminating horizontal lap seams and weak transition points.

LAYER 05 / FLASHING & EDGES

Hemmed Drip Edges & Soldered Scuppers

Heavy-gauge aluminum perimeter flashings with continuous cleat locking. All transitions, valley centers, and sidewalls are triple-sealed with butyl mastic tape and mechanical counter-flashings.

LAYER 06 / VENTILATION

Perforated Ridge Ventilation System

Engineered baffle-integrated ridge vents expel trapped attic moisture and superheated air while mechanically blocking hurricane-driven windward water intrusion.

Forensic Execution

Our 6-Phase Metal Roof Installation Protocol

Every metal roof replacement follows our rigorous Florida Building Code verified workflow from permit filing to municipal close-out.

01

Complete Tear-Off & Substrate Inspection

All existing tile, shingle, or modified bitumen layers are removed down to clean structural timber. Our master carpenter inspects rafters, trusses, and fascia for concealed dry rot or termite degradation.

02

HVHZ Deck Re-Nailing & City Inspection

We re-nail all plywood sheathing using 8d ring-shank nails placed every 6 inches along trusses. We host the official city building inspector on-site to sign off on the structural deck verification before underlayment installation.

03

Self-Adhering Secondary Water Barrier

We install direct-to-deck Polyglass Polystick XFR self-adhering membrane with 3-inch side laps and 6-inch end laps, sealed with asphalt mastic around all pipe vents, chimneys, and wall flashings.

04

CNC On-Site Panel Rollforming

Using portable computerized rollformers, panels are formed directly from 24-gauge Galvalume or .032" aluminum coils on your driveway. This guarantees zero shipping dents and continuous full-length panels from ridge to eave.

05

Concealed Clip Fastening & Mechanical Seam

Panels are secured with engineered clips and stainless steel fasteners. For mechanical lock profiles, our electric seamer folds each rib into a watertight 180-degree double-lock seam that cannot blow off in hurricane winds.

06

Final Municipal Sign-Off & Wind Mitigation

We accompany the municipal inspector for final permit closure and issue you an executed Form OIR-B1-1802 Wind Mitigation packet so you can immediately submit it to your insurance carrier for rate reductions.

Insurance & Economics

How a Metal Roof Slashes Your Florida Insurance Premiums

Florida homeowners face some of the highest property insurance rates in the nation. Installing a certified standing seam metal roof triggers the highest allowable discounts on your annual windstorm mitigation schedule.

A

Roof Covering Credit (FBC Equivalent)

Meets Section 1 of Form OIR-B1-1802 for 2001 or newer Florida Building Code compliance.

B

Roof Deck Attachment Credit (Level C)

8d ring-shank nails spaced at 6" along every framing rafter maximizes uplift resistance credits.

C

Secondary Water Resistance (SWR) Credit

Self-adhered peel-and-stick Polyglass underlayment direct-to-deck provides maximum water barrier qualification.

Estimated 20-Year Financial Comparison

Standard Shingle Roof (15-Yr Life) Total: $42,000+

Requires 2 replacements over 30 years + higher insurance premiums ($4,500/yr).

Smart Roofing Standing Seam Metal Net Savings: $28,500+

Single installation lasts 50+ years + 25% to 35% annual windstorm insurance reduction ($1,200/yr savings).

Quality Assurance

Common Metal Roofing Failure Modes (And How We Prevent Them)

Substandard metal roof installations frequently fail in South Florida due to thermal tension, cheap fasteners, and dissimilar metal reactions.

FAILURE MODE 01

Exposed Fastener Gasket Degradation

Cheaper 5V-crimp roofs use exposed screws with neoprene washers. Under relentless Florida UV radiation, rubber washers dry-rot and crack within 7–10 years, causing hundreds of screw-hole leaks.

Smart Solution: 100% Concealed Clip Systems
FAILURE MODE 02

Thermal Oil-Canning & Panel Buckling

Inexperienced installers over-tighten clips, locking the panels in place. When panels expand under 140°F afternoon sun, the trapped metal warps and buckles into unsightly waves ("oil-canning").

Smart Solution: Floating Thermal Expansion Clips
FAILURE MODE 03

Galvanic Metal Corrosion

When copper flashings or galvanized steel screws touch aluminum panels in moist, salty coastal air, rapid electrolytic corrosion destroys the metal sheet within months.

Smart Solution: Isolated Compatible Stainless Fasteners
