Roof waterproofing can effectively prevent rainwater and moisture from penetrating into the interior of the building, ensuring that the indoor space is dry and comfortable. This not only helps protect furniture, electrical appliances and decorative materials from water damage and prolongs their service life, but also prevents the growth of mold and bacteria, maintains indoor air quality and protects the health of residents. In addition, good waterproofing performance can also improve the overall structural stability of the building, avoiding structural damage and repair costs caused by water leakage.
