The answer to 'skylight damage' is that there are several common causes, including leaks, cracks, and seal failure. Symptoms may include water stains, mold growth, and drafts. Solutions can range from minor repairs to full skylight replacement, depending on the severity of the damage.
If the damage is minor, such as a cracked seal or small leak, homeowners may be able to perform DIY repairs. However, for more extensive damage or if you are unsure of the root cause, it is best to call a professional roofing contractor. They can properly diagnose the issue and provide the appropriate repair or replacement solution.
