Wind-driven Rain
Wind-driven Rain | Roofing | Mulberry
Brutal summer squalls and surprise afternoon downpours are a way of life in Mulberry, and when those winds start pushing rain sideways your roof needs more than ordinary protection. HEP’s wind-driven rain system is engineered for the Gulf Coast’s fiercest weather, sealing vulnerable seams, valleys, and edges so moisture can’t creep beneath the shingles. By combining advanced water-shedding membranes with hurricane-rated fasteners, we create a fortress overhead that keeps attics dry, energy bills steady, and peace of mind intact—even when the radar turns red.
From the first free inspection to the final cleanup, our local crews bring craftsmanship, clear communication, and a respect for your property that’s every bit as important as technical skill. We navigate insurance claims, offer flexible financing, and back each installation with iron-clad warranties, because we believe every neighbor deserves confidence in their roofing. When the next storm barrels across Polk County, you’ll be ready to watch the rain—not worry about it.
FAQs
What exactly is wind-driven rain and why is it a concern for Mulberry homeowners?
Wind-driven rain occurs when strong winds push rainfall horizontally or at a steep angle, forcing water under shingles, flashing, siding, and other building joints that would normally shed vertically falling rain. Mulberry’s location in Central Florida exposes roofs to frequent summer thunderstorms, tropical storms, and occasional hurricanes with gusts that easily exceed 60–100 mph. In these conditions, water can be blown upward under roof coverings or through small gaps, leading to leaks, deck rot, mold, and premature roof failure if the assembly is not specifically designed to resist it.
How can wind-driven rain damage my roof and home if it looks perfectly fine from street level?
Because wind can push water uphill, it can infiltrate areas that are hidden to the naked eye: under shingle laps, along the roof edge, through ridge vents, around plumbing boots, and behind wall-to-roof transitions. Once inside, moisture saturates underlayment and sheathing, causing plywood delamination, rusted nails, wet insulation, ceiling stains, and eventually structural decay. The damage may remain concealed until you notice interior leaks or sagging drywall, at which point repairs can be extensive. That is why a roof specifically rated and detailed for wind-driven rain resistance is critical in Mulberry’s storm-prone climate.
What signs should I look for that suggest wind-driven rain has already compromised my roof?
Common indicators include: (1) dark spots or streaks on interior ceilings or walls after a storm; (2) damp or rotted wood in the attic, especially near ridges, hips, and eaves; (3) lifted or creased shingles along roof edges; (4) water stains around skylights, chimneys, or dormers; (5) granule loss in specific patterns rather than evenly across the roof; and (6) musty odors in attic insulation. If you observe any of these, schedule a professional inspection promptly, because small wind-driven rain intrusions can expand quickly during the next heavy squall.
How does your wind-driven rain roofing system protect homes in Mulberry?
We combine multiple defenses that meet or exceed the Florida Building Code for Polk County’s 120-mph basic wind speed zone: • Self-adhering waterproof membrane (peel-and-stick) at all eaves, valleys, and penetrations to seal nail holes. • Synthetic underlayment with high tear strength for secondary moisture protection. • Shingles and accessories tested to ASTM D7158/D3161 Class F or a metal roof panel system with UL 580 Class 90 uplift ratings. • Enhanced nailing patterns (6-nails per shingle) and ring-shank nails to resist uplift. • Closed-cut or woven valleys, storm-lock starter strips, and oversized drip edge that blocks wind-lift at the perimeter. • Properly baffled ridge vents and sealed sidewall flashings that prevent wind-blown water entry while maintaining attic ventilation. Together, these features create a continuous weather-tight barrier proven to withstand driving rain in hurricane-force winds.
Do I need special permits or inspections in Mulberry for a wind-driven rain-resistant roof?
Yes. Polk County enforces the Florida Building Code (FBC), which requires roofing permits for any reroof over 500 sq ft or structural repairs. Permit drawings must reference products with Florida Product Approval or Miami-Dade NOA numbers that document wind-driven rain resistance. After installation, a county inspector verifies deck nailing, underlayment placement, flashing details, and final covering. Hiring a licensed roofing contractor familiar with FBC High-Velocity Hurricane Zone guidelines ensures your roof passes inspection and remains eligible for manufacturer warranties and insurance coverage.
How much does a wind-driven rain-resistant roof cost in Mulberry, and will my insurance help?
Pricing depends on roof size, pitch, material, and the level of reinforcement. On average, asphalt shingle systems designed for wind-driven rain run $4.75–$6.50 per sq ft, while standing-seam metal ranges $8–$12 per sq ft. Upgrades such as peel-and-stick membranes or stainless steel fasteners add roughly 5–10 % to a standard reroof but pay for themselves by preventing costly water damage. Many insurers offer discounts of 5–15 % for FBC-compliant wind mitigation features, and some will cover a portion of the replacement cost if your current roof was storm-damaged. We provide free inspections, written estimates, and assistance with the Uniform Mitigation Verification form (OIR-B1-1802) to maximize any available savings.
