Should You Repair or Replace a Roof in Moon Township?

Local context, not a score

The median Moon township structure was built in 1980. A house from that period may already be on a second or third roof. Age alone is not a replacement trigger, but it is a reason to ask how much original decking and flashing remain.

Repair may make sense when

• Damage is isolated to one penetration, one valley, or a small shingle field.
• The roof otherwise has meaningful useful life remaining.
• The leak source can be clearly identified from the attic or a professional inspection.
• A matching product is still available so the repair will shed water correctly.

Replacement may make sense when

• Shingles are broadly deteriorating, curling, or losing granules across planes.
• Multiple areas are failing in the same season.
• Decking or structural problems are widespread.
• Repair costs are becoming repetitive.
• You are already planning a material change, such as asphalt to metal.

Questions that change the answer

• How many layers are on the roof now?
• Is the leak happening only during ice-dam thaws?
• Has ventilation or insulation been addressed, or only the shingles?
• Would the work stay “roof covering,” or become structural under Moon Township rules?
