The answer to 'shingles cracked' is that cracked or damaged shingles are a common roofing problem that can have several underlying causes. Shingles may crack due to age, weather exposure, improper installation, or impact damage. Symptoms include visible cracks, curling, or missing granules on the shingles. Solutions can range from repairing or replacing individual shingles to a full roof replacement, depending on the extent of the damage.
In general, repairing a few cracked shingles is a manageable DIY project for homeowners with some roofing experience. However, more extensive damage or a full roof replacement should be handled by a professional roofing contractor to ensure the job is done properly and safely. Attempting major roofing work without the right skills and equipment can lead to further damage or safety hazards.
