The answer to 'flashing curling shingles' is that curling shingles are a common roofing problem often caused by improper installation, age, or weather exposure. Curling shingles can lead to leaks, water damage, and other serious issues if not addressed. The most common causes are poor ventilation, improper nailing, and normal wear and tear over time.
In many cases, curling shingles can be repaired or replaced by a skilled DIY homeowner. However, if the problem is widespread or the roof is older, it's best to consult a professional roofing contractor who can properly assess the situation and provide the best solution. Attempting major roof repairs without the right experience can lead to further damage and safety hazards.
