Skylights can brighten up a space and add a touch of elegance to your home, but when they start to leak, they can quickly turn into a homeowner’s nightmare. Identifying the root cause of the leak is the first step toward a proper fix. In this blog, we’ll explore five common reasons skylights leak and how to address them effectively.
Understanding Hillsboro, OR Weather and Its Impact on Skylights
Hillsboro, OR, experiences a diverse range of weather conditions that can exacerbate skylight issues. The city’s climate includes wet winters, mild summers, and occasional heavy storms. These factors contribute to wear and tear on skylights, increasing the likelihood of leaks. Here’s how local weather impacts skylights:
- Heavy Rainfall: Hillsboro receives an average of 40 inches of rain annually, mostly concentrated in the fall and winter months. Prolonged exposure to moisture can weaken seals and flashing around skylights.
- Temperature Fluctuations: The shift between cool, damp winters and warm summers causes expansion and contraction in skylight materials, which may lead to cracks or seal failure.
- Storm Damage: High winds and storms can dislodge flashing, crack glass, or introduce debris that damages the skylight structure.
Understanding these conditions is crucial for identifying and preventing skylight leaks in Hillsboro and similar climates.
1. Improper Installation
A poorly installed skylight is one of the most common reasons for leaks. If the unit isn’t seated correctly or the flashing isn’t installed properly, water can seep through the gaps.
Fix:
- Remove the skylight and inspect the opening for irregularities.
- Reinstall the skylight, ensuring a snug fit.
- Use high-quality flashing and follow the manufacturer’s installation guidelines.
Pro Tip: Always hire a certified professional if you’re unsure about installation procedures.
2. Damaged Flashing
Flashing is the metal or rubber seal that surrounds the skylight, directing water away from the edges. Over time, flashing can crack, corrode, or become loose, leading to leaks.
Fix:
- Inspect the flashing for visible signs of wear or damage.
- Replace old or damaged flashing with a new, weather-resistant material.
- Apply a waterproof sealant to ensure tight protection around the edges.
Pro Tip: Regularly check the flashing after severe weather to catch early signs of wear.
3. Worn-Out or Cracked Seals
The seals around your skylight can deteriorate due to age, UV exposure, or fluctuating temperatures, causing gaps where water can enter.
Fix:
- Remove old sealant or gasket material using a putty knife.
- Clean the area thoroughly to remove dirt and debris.
- Apply a fresh layer of high-quality silicone or rubberized sealant around the perimeter.
Pro Tip: Opt for UV-resistant sealants to prolong the life of your skylight seals.
4. Condensation Buildup
While condensation itself isn’t a leak, excessive moisture can mimic one by dripping into your home. Poor ventilation often contributes to this issue.
Fix:
- Improve ventilation in the room by installing exhaust fans or opening windows.
- Insulate the skylight to reduce temperature fluctuations.
- Check for any cracks or gaps that might be exacerbating the condensation problem.
Pro Tip: Consider installing double-pane or low-E glass skylights to minimize condensation.
5. Cracked or Broken Glass
Physical damage to the skylight glass, whether from hail, tree branches, or accidents, can create direct paths for water to enter your home.
Fix:
- Assess the extent of the damage to determine if the glass can be repaired or needs replacing.
- Use a temporary waterproof patch for small cracks until professional repairs can be made.
- Replace the glass panel entirely if the damage is significant.
Pro Tip: Installing impact-resistant skylights can prevent future damage from severe weather.

- Remove Debris After Storms: Check your roof and skylight for debris after heavy storms to avoid damage.
- Schedule Professional Maintenance: Hire a roofing specialist to inspect and maintain your skylights annually, especially before winter.
