A leaking skylight can cause homeowners a big headache and expense. Let’s take a look at what causes a skylight to leak when it rains and what DIY steps you can take to prevent this issue.
Common Causes Of Skylights Leaking When It Rains
Below are five common causes of skylights leaking during or after heavy rainfall.
Damaged Flashings Or Frames
Flashings and frames can ultimately become damaged or corroded. Improper installation is typically to blame here, especially when the skylight begins to leak.
These issues can result in cracks that allow water to seep through. This can result in potential water damage and compromised integrity of the structure.
Improper Installation
Poor installation is the biggest culprit when it comes to skylights leaking. Improper installation, including use of the wrong fasteners or failing to secure the roofing material properly, can result in problems.
Try using high-quality fasteners to significantly reduce the risk of leakage. You’ll want to ensure a secure and watertight connection between the skylight and metal roofing.
Excess Condensation
Condensation can build up and drip, making homeowners believe there may be some leakage. The weather conditions, of course, will play a significant role in creating condensation.
Damaged Roofing
Damaged roofing and the surrounding areas can sometimes direct the water to the skylight’s location. This will eventually lead to the skylight leaking when it rains.
Cracked Or Worn Seals/Sealants
While outdoor seals and sealants are specifically designed to withstand even the harshest elements, they are still considered consumables. Both will gradually degrade and crack as time goes. This will eventually lead to some minor leakage.
How To Prevent Skylight Leaks
Here are a few quick tips to prevent any future leaks coming from your skylights:
- Ensure any installation is done professionally and properly.
- Fix any existing damage to the frames or flashings as soon as it is noticed.
- Inspect your roof regularly for any potential dangers.
- Weep gutters and holes should also be inspected regularly, as well as cleaned thoroughly.
- Replace any broken skylights.
- Improve the insulation and circulation with the addition of ventilation holes.
- Reapply the sealant and replace the seals at the first indication of leakage.
