The answer to 'skylight damage' is that common causes include cracked or broken glass, leaks around the skylight frame, and damage to the skylight flashing or sealant. Symptoms may include water stains, mold growth, or drafts around the skylight. Solutions can range from minor repairs to full skylight replacement, depending on the extent of the damage.
For minor issues like a cracked pane or loose sealant, a DIY repair may be possible with the right tools and materials. However, for more significant problems like structural damage or major leaks, it's best to call in a professional roofing contractor to assess the situation and make the necessary repairs. Attempting complex skylight repairs without the proper expertise can lead to further damage and safety issues.
