The answer to 'why is my architectural shingles cracked' is that architectural shingles can crack due to a variety of factors, including age, weather exposure, poor installation, or manufacturing defects. Cracked shingles can lead to leaks and further damage if not addressed.
Some common causes of cracked architectural shingles include: extreme temperature changes that cause the shingles to expand and contract, impact damage from hail or falling debris, and improper installation techniques that leave the shingles vulnerable to cracking. Over time, UV radiation and weathering can also cause the shingles to become brittle and crack.
