Skylights are a beautiful addition to any home, offering natural light and expansive views. However, they are also exposed to the elements and can suffer from weather-related damage. Understanding how different weather conditions can affect skylights and the available repair options is essential for homeowners looking to maintain their integrity and beauty. Here’s a comprehensive overview.
Types of Weather Damage to Skylights
1. Rain and Moisture Damage
Excessive rain can lead to leaks if water penetrates the seals or flashing around the skylight. Moist environments can also cause mold and mildew to develop, particularly in poorly ventilated areas.
2. Snow and Ice Accumulation
Heavy snow or ice can put significant stress on skylights, especially on flat roofs. The weight of the snow can lead to structural damage, while melting and refreezing can create ice dams that block drainage paths.
3. UV Damage
While skylights allow sunlight in, prolonged exposure to UV rays can degrade materials over time. This is particularly evident in plastic or acrylic skylights, where discoloration and brittleness can occur.
4. Hail Damage
In areas prone to severe storms, hail can cause immediate physical damage to skylights. Cracks or breaks in the glass can occur, significantly compromising their integrity.
5. High Winds
Strong winds can cause debris to strike skylights, leading to cracks or damage to the frame. Wind-driven rain can also exploit any existing vulnerabilities, leading to leaks.
Identifying Weather-Related Damage
Inspecting Skylights
Regular inspections are crucial for identifying weather-related damage early. Key areas to inspect include:
- Seals and Flashing: Look for cracks or gaps that may allow water to seep in.
- Glass Condition: Check for any visible cracks, chips, or signs of wear on the glass.
- Interior Signs: Water stains, mold, or discoloration on walls or ceilings can indicate a leak.
When to Perform Inspections
Conduct these inspections following severe weather events or seasonally—preferably at the start of fall and spring—to proactively address any issues before they worsen.
Repair Options for Weather Damage
1. Resealing and Caulking
If seals have degraded or cracked, resealing or recaulking the skylight can help restore its integrity. This is often a quick and cost-effective skylight repair.
Steps:
- Remove old caulk with a putty knife.
- Clean the surfaces thoroughly.
- Apply new exterior-grade silicone sealant evenly along the seams.
2. Flashing Replacement
Damaged or poorly installed flashing can lead to leaks. Replacing the flashing can create a better barrier against water infiltration.
Steps:
- Remove existing flashing.
- Inspect the roof for any damage or rot before installation.
- Install new flashing, ensuring it overlaps properly with roofing material.
3. Glass Replacement
If your skylight has suffered from hail damage or severe cracking, replacing the glass is often the best option.
Steps:
- Remove the skylight frame carefully.
- Measure for precise glass replacement.
- Install new glass and secure it with appropriate frames and seals.
4. Insulation Improvement
In areas prone to cold temperatures, improving insulation around the skylight can help prevent condensation and ice buildup.
Steps:
- Check the attic or ceiling insulation near the skylight.
- Install additional insulation if necessary, ensuring a tight fit to minimize heat loss.
5. Professional Maintenance
Sometimes, weather damage may require professional help. Consult a roofing expert for a thorough assessment and repairs beyond basic sealing or glass replacement.
Preventing Weather Damage
1. Quality Installation
Ensuring your skylight is installed correctly the first time is key to preventing many weather-related problems.
2. Regular Maintenance
Routine check-ups and maintenance can help catch issues early, preventing them from escalating.
3. Consider Upgrading
If your skylight is older and prone to issues, consider upgrading to modern, energy-efficient models designed to withstand severe weather.
Conclusion
Weather damage can significantly impact the functionality and aesthetics of skylights. By understanding the types of damage that can occur, how to identify issues, and the corresponding repair options, homeowners can take proactive steps to protect their investment. Regular inspections, timely repairs, and preventative maintenance will ensure that skylights continue to bring warmth and light into your home for years to come.
