The answer to 'why is my shingles cracked' is that cracked shingles are usually caused by age, weathering, or physical damage. Over time, shingles can become brittle and crack due to exposure to sunlight, rain, and temperature changes. Physical damage from falling tree branches, hail, or other impacts can also cause shingles to crack.
Cracked shingles can lead to leaks and further damage to your roof if not addressed. Symptoms of cracked shingles include visible cracks, curling or warping of the shingle, and leaks in your home. To fix cracked shingles, you may be able to DIY by replacing individual shingles, but for more extensive roof damage, it's best to call a professional roofing contractor to inspect and repair your roof.
