The answer to 'when to replace roof inspection' is that most roofs need to be inspected and potentially replaced every 20-25 years. This timeframe can vary depending on the type of roof material, the climate, and the overall condition of the roof. Regular inspections are important to identify any damage or wear and tear that may require repairs or a full roof replacement.
During a roof inspection, a professional roofer will check for issues like missing or damaged shingles, cracks, leaks, and other signs of deterioration. They can then provide recommendations on whether the roof needs to be repaired or completely replaced. Replacing a roof is a significant investment, so it's best to have a professional assess the condition and provide guidance on the best course of action.
