The answer to 'skylight damaged' is that a damaged skylight can have several common causes, including broken or cracked glass, leaks around the skylight frame, and damage to the flashing or sealant. Symptoms may include water leaks, condensation, 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 cracked glass or loose sealant, a DIY repair may be possible with the right tools and materials. However, for more significant damage or leaks, it's best to call in a professional roofing contractor. They can properly diagnose the problem, make the necessary repairs, and ensure the skylight is properly sealed and integrated with the roofing system to prevent future issues.
