How Hurricanes Expose Hidden Leak Points in Buildings
When we think about hurricane damage, the immediate images that come to mind are often of uprooted trees, shattered windows, and flooded streets. However, the real danger for many buildings lies in the unseen areas that are particularly vulnerable to leaks during such severe weather events. The powerful winds and torrential rains of a hurricane can force water into places it wouldn’t normally reach during regular rainstorms. In this blog post, we’ll explore some of these hidden vulnerabilities we have seen during our years of waterproofing work.
Glazing Joints in Windows

Glazing joints, the seals between the glass and the window frame, are critical for maintaining a watertight seal. Over time, these joints can degrade due to exposure to the elements, UV radiation, and thermal expansion and contraction, which can be extreme in our Florida weather. During a hurricane, the intense wind-driven rain can exploit any weaknesses in these joints, forcing water into the building. Regular inspection and maintenance of glazing joints are essential to ensure they remain intact and effective in keeping out water.
Perimeter Joints of Windows

Similar to glazing joints, the perimeter joints around windows are another vulnerable area. These joints, where the window frame meets the wall, can deteriorate due to aging, poor installation, or thermal movement. In normal conditions, minor issues might not pose a significant problem, but under hurricane conditions, these weak points can become pathways for water intrusion. Sealing and caulking around window perimeters should be part of regular building maintenance to prevent potential leaks during severe storms.
Mortar Joints in Brick and Block

Brick and block walls are generally robust, but the mortar joints that hold them together can be a weak link. Mortar can crack and erode over time, creating gaps that can allow water to seep through. During a hurricane, wind-driven rain can penetrate these small openings, leading to water damage inside the building. Regular inspection and repointing of mortar joints can help maintain the integrity of brick and block walls, preventing water ingress during extreme weather. Tuck pointing is an art, so make sure you use a team with the proper skill set and tools to complete quality work for you.
Roof Scuppers

Roof scuppers are drainage devices that help direct water off flat or low-slope roofs. If these scuppers become clogged with debris, they can cause water to back up, leading to ponding on the roof. Prolonged ponding can find new entry points into the building, exacerbating water damage. It’s crucial to ensure that roof scuppers are clear and functioning correctly, especially before the hurricane season. Regular maintenance and cleaning of roof scuppers will help make sure water flows properly through your drainage system and away from your building.
Preventative Measures and Maintenance
To safeguard your building against the hidden leak points exposed during hurricanes, it’s essential to adopt a proactive approach to maintenance. Here are some tips:
- Regular Inspections: Conduct thorough inspections of glazing joints, window perimeters, mortar joints, and roof scuppers at least twice a year and after any major storm. We are happy to help you with these inspections.
- Prompt Repairs: Address any signs of wear and tear, such as cracked mortar, degraded sealant, or clogged scuppers, immediately to prevent further deterioration. Make sure you use a team who understands the building and the substrates, so they complete the proper prep and use the best materials for each project.
- Professional Assessments: Engage a professional company, like Remediation Specialists to assess and repair any vulnerabilities, ensuring that your building is as storm-proof as possible.
- Preparation: Before hurricane season, take the time to clear gutters and roof scuppers, check all seals, and reinforce any weak points. Check out our Hurricane Prep Checklist to help with this task.
By understanding and addressing these unseen vulnerabilities, you can better protect your building from the severe water damage that hurricanes can cause. Regular maintenance and timely repairs are your best defenses against the powerful forces of nature, ensuring your building remains safe and dry through the storm.
