West Palm Beach FL roof replacement permit rules
West Palm Beach Building Services requires a building permit for full roof replacements. Apply at wpb.org. Florida certified roofing contractor required (myfloridalicense.com). Call (561) 805-6700 for documentation requirements. The building inspector will verify nail pattern, secondary water barrier installation, starter strip installation, and hip/ridge cap method — all high-wind critical details.
Florida Building Code requires wind-rated roof installation for Palm Beach County's approximately 140 mph (3-second gust) design wind speed. This means: a specific nail pattern (typically 6 nails per shingle rather than 4), correct exposure (nail placement within the manufacturer's specified zone), starter strips at all eaves and rakes, and proper hip and ridge cap installation. These are not optional enhancements — they are code-required for the wind zone. A contractor who doesn't proactively discuss FBC wind installation requirements in a West Palm Beach roof quote hasn't done enough South Florida work.
The Florida Building Code requires a secondary water barrier on all reroofs — a peel-and-stick or self-adhering underlayment applied over the roof deck before shingles. This product protects the home against water infiltration if shingles are lost or lifted in a tropical storm or hurricane. It serves the same protective purpose as ice and water shield in northern climates, but addresses storm-driven rain rather than ice dams. Verify that the secondary water barrier is explicitly included in any contractor's quoted scope — it's common for contractors to omit this on cost-competitive bids.
West Palm Beach's CBS construction means many homes have flat or low-slope roof sections — the main dwelling may be low-slope modified bitumen or EPDM, with the entrance or garage having a separate pitched section. Flat roof replacement is a different scope from shingle reroof: flat roofing typically uses modified bitumen, EPDM, or TPO systems. Confirm that the contractor has specific flat-roof experience and appropriate licensing for the flat-roof scope.

Common questions about West Palm Beach, FL roof replacement permits
What is the Florida secondary water barrier requirement for roofing?
Florida Building Code requires a secondary water barrier — a peel-and-stick or self-adhering underlayment applied to the roof deck before shingles — on all reroofs. This product protects the home against water infiltration if shingles are lost or lifted during a tropical storm or hurricane. It's the Florida equivalent of ice and water shield, but protecting against storm-driven rain rather than ice dams. Verify it's explicitly in any contractor's scope before signing.

These are code-required, not optional upgrades. The building inspector verifies these details at inspection.
