The answer to 'why is my flat roof cracked' is that flat roofs are prone to cracking due to a variety of factors, including age, weathering, and improper installation. Cracks in a flat roof can allow water to seep in, leading to leaks, water damage, and even structural issues if left unaddressed.
Some common causes of flat roof cracking include exposure to UV radiation, thermal expansion and contraction, and poor drainage that allows water to pool on the roof. Over time, the roofing material can become brittle and start to crack, especially in areas with high foot traffic or where the roof has been patched or repaired previously.
