Do Hurricane Screens Keep Water Out?

Last Updated: March 2026
Hurricane screens significantly reduce water intrusion during a storm, but they do not create a watertight seal. Their primary job is stopping windborne debris from breaching your windows and doors. That is the most important function, because a broken window during a hurricane allows massive amounts of wind-driven rain into your home in seconds. Screens prevent that breach. They also significantly reduce wind velocity, which dramatically cuts the force driving rain into and around your openings.

However, fabric hurricane screens are permeable by design. Water can pass through the weave, and some moisture will reach the window or door surface behind the screen. For most homeowners, this is the right trade-off. A small amount of moisture on an intact window is a manageable nuisance. A shattered window with unrestricted wind and rain entering your home is a catastrophe.

Below you will find answers to additional frequently asked questions about hurricane screens, water, and storm protection.

How Do Hurricane Screens Protect Against Wind-Driven Rain?

To understand what screens do for water, you need to understand how water enters homes during hurricanes. The Insurance Institute for Business and Home Safety (IBHS) researches wind-driven rain entry as a major cause of hurricane damage. Their findings show that water intrusion during hurricanes comes from multiple pathways, not just through windows.

Hurricane screens address the two most damaging pathways:

Pathway 1 – Debris breach (catastrophic): A broken window or door creates an open hole in your building envelope. Wind drives rain directly into living spaces. Interior damage is immediate and severe. This is the most expensive form of water damage during a hurricane. Screens prevent it entirely by absorbing debris impact.

Pathway 2 – Wind pressure forcing water through gaps (significant): Even with intact windows, extreme wind pressure can push water through seals, tracks, and weatherstripping. The American Architectural Manufacturers Association (AAMA) notes that hurricane conditions can exceed a window’s rated water penetration resistance. Screens significantly reduce the wind speed hitting the window surface. Lower wind speed means lower pressure. Lower pressure means significantly less water forced through gaps.

Pathway 3 – Moisture through the screen weave (minor): Some rain will pass through the fabric and reach your windows. This is the trade-off for maintaining visibility and airflow. The amount is small compared to what would hit the glass without a screen, because the screen breaks up the rain’s velocity and direction.

Here is how that compares across protection types:

Protection Type	Stops Debris?	Reduces Wind at Window?	Water Barrier	Visibility When Deployed
Hurricane Screens	Yes (code-tested)	Significantly reduces wind speed at window surface	Partial – reduces rain reaching glass, does not seal	Filtered (can see out)
Accordion Shutters	Yes (code-tested)	Near 100%	Good – solid barrier, minor leakage at track joints possible	None (total blackout)
Roll Down Shutters	Yes (code-tested)	Near 100%	Good – tighter seal than accordion, small gaps at edges	None (total blackout)
Storm Panels	Yes (code-tested)	Near 100% (metal) / Partial (clear)	Moderate – gaps between panel edges can admit water	None (metal) / Good (clear polycarbonate)
Impact Windows	Yes (code-tested)	N/A (no exterior barrier)	Best – sealed unit with tested water penetration resistance	Full (clear glass)

No hurricane protection product is 100% waterproof during a major hurricane. Even impact windows have rated water penetration limits that extreme storms can exceed. Even solid metal shutters can admit water at track joints and edge seals. The AAMA’s white paper on storm-driven rain penetration confirms that hurricane conditions frequently exceed the water penetration resistance ratings of products that otherwise performed well structurally.

Can Hurricane Screens Stop Flying Debris from Causing Water Damage?

This is the question that matters most. The majority of serious water damage during hurricanes comes not from rain passing through a shutter or screen, but from breached openings. One broken window or shattered sliding glass door exposes your entire interior to the storm.

Consider the math. IBHS research found that an unsealed roof deck allows up to 60% of the rain hitting a damaged roof to enter the attic. A sealed roof deck reduces that by up to 95%. The same principle applies to windows. An intact, covered window lets almost no water into your home. A broken window lets wind and rain pour in with no restriction.

Storm Smart’s Storm Catcher® screens are tested under ASTM E1886 and E1996 protocols. That means they have absorbed a 9-pound 2×4 lumber missile fired at 50 feet per second and then survived 9,000+ cycles of positive and negative pressure. If the screen holds, your window stays intact. If your window stays intact, the catastrophic water entry path is closed.

The debris protection function of hurricane screens prevents more water damage than any water-sealing feature ever could.

How Do Hurricane Screens Reduce Interior Wind Pressure?

When a window breaks during a hurricane, wind enters the building and pressurizes the interior. This internal pressure pushes outward on the roof and walls from inside, while hurricane winds push inward from outside. The combined force can lift the roof off the structure.

Hurricane screens prevent this by keeping the building envelope sealed. The screen absorbs wind and debris energy outside the window plane. Your windows and doors remain intact. Internal pressure stays balanced. The structure holds.

This pressure stabilization also matters for water intrusion. Wind-driven rain enters buildings through gaps in proportion to the pressure differential across the building envelope. Higher pressure differential means more water pushed through every small gap, seal, and joint. 

By significantly reducing wind speed at the window surface, screens dramatically cut that pressure differential. Less pressure means less water forced through your windows’ weatherstripping and seals, even without a watertight barrier. 

What Makes Hurricane Screens Different from Solid Shutters for Water Protection?

The honest answer: if your top priority is keeping every drop of water away from your window glass, solid metal shutters or impact windows will outperform fabric screens. This is a genuine trade-off.

Here is what you gain with screens that solid shutters cannot provide:

Visibility. Solid shutters create total darkness inside your home. During a storm that can last 6-12 hours (or longer, as when Hurricanes Helene and Milton hit Florida weeks apart in 2024), you cannot see outside. You cannot assess conditions. You cannot tell if the storm has passed or if you are in the eye. Screens maintain filtered visibility throughout the event.

Ventilation after the storm. Once the storm passes, screens allow airflow while still providing security. Solid shutters must be fully opened or remain fully closed. In the hours after a hurricane, when debris is still settling and conditions are uncertain, screens give you a middle ground.

Coverage of large openings. Lanais, oversized sliders, and irregular openings are difficult and expensive to cover with rigid shutters. Screens are designed for exactly these applications. A screened lanai opening that is difficult or prohibitively expensive to cover with Accordion Shutters can often be protected effectively with Storm Catcher® Hurricane Screens.

Rapid deployment. If you are sheltering in place and conditions deteriorate faster than expected, screens deploy in minutes from ground level without tools. Solid panel systems require more time and effort.

The trade-off is clear: screens give you debris protection, pressure reduction, and significant water reduction with visibility and convenience. Solid shutters give you slightly better water sealing with zero visibility and more complex deployment. Many homeowners use both: Hurricane Screens on the lanai and large openings, Accordion Shutters on standard windows.
