Have you been diligent about keeping your roof in tip-top shape, but still noticing signs of moisture in your home? If this has you confused, your bay windows may be the culprit. If you have water stains, increased condensation, or outright leaking from your bay windows, do not fret. The right roofing professional can find the source of the leak and make the needed repairs before more damage is done to your home. Here’s why bay windows leak and what you can do to mitigate any harm to your home.

Your Home’s Material

If you’ve found leaks by your bay window, your siding material may be to blame. If your home is covered with vinyl or wood siding and is leaking, the contractor may not have used the appropriate step flashing and/or apron flashing. These types of materials require an apron flashing that overlaps the corners of your bay window. If your home’s contractor cut corners, you may start seeing signs of leaking from a lack of apron flashings or even faulty installation. The best way to remedy this is to contact a trusted roofing company for repair. This is not a job for a DIYer. Every bay window is different and a pro will know how to install the correct material to direct the water away.

Window Casings

Another reason you may see leaks near your bay window is that the window casings are not sealed properly. If you notice signs of discoloration or water running down your windows, the casings need to be reapplied. According to Home Guides, silicone caulk on the exterior of the window is the best sealant choice. The sides of the window frames that are attached to the house may also be the source of leaks and should be properly caulked for optimal sealing ability. Sealing and resealing the windows, frames, panes, and other areas connected directly to siding provides the highest level of water protection. At RoofPRO, we can provide a full inspection of your bay window to determine if it is the casings, siding, or windows themselves that are causing your leaks. Our roofing team can reseal your windows in a timely manner and apply caulk as necessary.

The RoofPRO Difference

Not only do we protect your home’s roof, we provide bay window leaking services for maximum defense against water damage. During our inspection of bay windows, we will check all flashings behind the siding for proper installation. If your home is brick, we do a full examination of the caulk around the bay window edge. We also check for missing flashing, cracking in your siding, and test the soundness of the windows themselves. If problems are found during the inspection, our roofing pros can address those right on the spot.

To guarantee that we have addressed all leaking areas on your home, we can also perform a water test by spraying water on the bay windows. This allows us to watch for leaks in real time. We always want to confirm that all steps have been taken to prevent the recurrence of moisture in your home.
