The answer to 'signs of skylight damage' is that there are several common signs that a skylight may be damaged and in need of repair or replacement. These include leaks, cracks or holes in the skylight glass or frame, excessive condensation buildup, and visible damage to the sealant or flashing around the skylight.
Leaks are one of the most obvious signs of skylight damage, as water stains or drips around the skylight can indicate a problem with the seal or frame. Cracks or holes in the glass can also allow water to enter the home, while condensation buildup may signal issues with the skylight's insulation or ventilation. Damaged sealant or flashing can also contribute to leaks and should be inspected regularly.
