What should be checked around an old satellite-dish or antenna roof penetration?
Keep, remove or investigate a nearby leak
If the mount will remain, ask the roofer to evaluate its condition and how each penetration is protected. The assessment should distinguish equipment stability from water shedding. Neither a solid-looking bracket nor a recent sealant coating establishes that the hidden connection is sound.
If the equipment is to be removed, obtain a scope for restoring the openings and any disturbed shingles, flashing or underlayment. The quote should identify who removes the equipment and who accepts responsibility for the resulting roof work.
If a leak is nearby, ask the investigator to trace the water path rather than assume the old dish is the cause. Include other roof penetrations and intersections in the area. A stain’s position is useful context but cannot establish a single entry point.
