Understanding Hurricane Ratings for Skylights: What Coastal Homeowners Need to Know
Hurricane ratings for skylights aren’t just technical jargon—they’re your home’s first line of defense during severe coastal storms. When evaluating hurricane-rated skylights, you need to understand several critical factors that determine their ability to withstand extreme weather conditions.
Design Pressure (DP) Ratings
Design Pressure ratings measure how much wind force a skylight can withstand before failing. For coastal homes, look for skylights with DP ratings of +50/-50 or higher. These higher ratings indicate the skylight can resist both positive pressure (wind pushing against the skylight) and negative pressure (wind pulling the skylight outward) during hurricane conditions.
Impact Resistance Testing
Hurricane-rated skylights undergo rigorous missile impact testing where heavy objects are propelled at the glass at high speeds. Level D testing (the most stringent) simulates debris traveling at 50 feet per second—approximately 34 mph. Look for skylights that have passed large and small missile impact tests, ensuring they won’t shatter when struck by wind-borne debris.
Wind Zone Classifications
Coastal areas are typically categorized into wind zones based on their hurricane risk:
- Wind Zone 1: 130 mph
- Wind Zone 2: 140 mph
- Wind Zone 3: 150+ mph
Your location’s wind zone determines the minimum rating your skylights should have. Many coastal Florida counties, for example, require products rated for Wind Zone 3, while areas further inland might only require Wind Zone 1 ratings.
Water Infiltration Resistance
Beyond wind, hurricane-rated skylights must prevent water intrusion during driving rain conditions. Look for products tested for water infiltration at pressures of at least 15 pounds per square foot (psf), which simulates rain driven by hurricane-force winds.
Miami-Dade County Approval
Products with Miami-Dade County Notice of Acceptance (NOA) have met the strictest hurricane resistance standards in the country. This certification requires passing tests for wind resistance, impact protection, and water infiltration. For coastal homes in high-risk areas, Miami-Dade approved skylights provide exceptional peace of mind.

Frequently Asked Questions
What makes skylights vulnerable during hurricanes?
Standard skylights are often weak points during hurricanes because they lack impact resistance and proper sealing. During severe storms, they can crack or shatter from flying debris, allowing water to enter and cause significant structural damage. Their frames may also fail under extreme wind pressure, compromising your home’s protective envelope when you need it most.
What is a Design Pressure (DP) rating for skylights?
A Design Pressure rating indicates how much wind force a skylight can withstand. For coastal homes in hurricane-prone areas, experts recommend skylights with DP ratings of +50/-50 or higher. This measurement represents the skylight’s resistance to both positive pressure (wind pushing against the surface) and negative pressure (wind pulling away from the surface).
How are hurricane-rated skylights tested?
Hurricane-rated skylights undergo rigorous missile impact tests where projectiles are launched at high speeds to simulate flying debris. They must also pass cyclic pressure tests that mimic hurricane wind conditions and water infiltration testing. The most stringent testing follows Miami-Dade County protocols, which require skylights to withstand impacts without creating openings in the building envelope.
What makes VELUX skylights hurricane-resistant?
VELUX hurricane-resistant skylights feature laminated glass that remains intact even when shattered, reinforced frames with extra fastening points, and specialized flashing kits. They withstand winds up to 140 mph and have passed Miami-Dade County missile impact tests. Their patented step-flashing method prevents water infiltration during heavy rains, providing comprehensive storm protection.
Do hurricane-rated skylights offer energy efficiency benefits?
Yes, many hurricane-rated skylights like Fakro’s models offer significant energy efficiency benefits. They typically feature Low-E coatings and argon gas fills that block 99.9% of UV rays and reduce heat transfer. Models with a Solar Heat Gain Coefficient (SHGC) of around 0.30 balance natural light with heat rejection, potentially lowering cooling costs by up to 25% in tropical climates.
Are acrylic dome skylights hurricane-resistant?
Yes, specially designed acrylic dome skylights like Wasco’s hurricane-rated models can withstand hurricane conditions. They feature extruded aluminum frames with reinforced corners, multi-point locking systems to prevent air infiltration, and acrylic domes designed to flex rather than shatter upon impact. Quality models can withstand winds up to 130 mph when properly installed.
What are tubular skylights and are they hurricane-safe?
Tubular skylights are compact daylighting solutions that channel sunlight through a reflective tube from roof to ceiling. Models like Solatube’s impact-resistant versions are specifically designed for hurricane conditions with low-profile domes that minimize wind resistance. They offer equivalent storm protection to traditional skylights but typically cost 30-40% less and can be installed where conventional skylights won’t fit.
How important is professional installation for hurricane-rated skylights?
Professional installation is critical for hurricane-rated skylights. It ensures proper integration with your roof system using specialized flashing kits, hurricane-grade sealants, and manufacturer-specified techniques. Even the highest-rated skylight will fail during a storm if improperly installed. Many manufacturers require professional installation to maintain warranty coverage in hurricane-prone regions.
