A common culprit is roof vents. One frequent mistake occurs during installation: new vents often have a mould release agent on the plastic from manufacturing. If this isn’t removed, sealant won’t bond properly, leading to leaks.

How to fix it:
Lightly sand the plastic surfaces that will sit against the roof using fine-grit sandpaper. This helps the sealant adhere properly. After sanding, clean the area thoroughly with warm water and mild dish soap to remove any residue. Ensure it is completely dry before applying sealant and installing the vent.

Taking this extra step during installation can prevent future leaks and costly water damage.
