The answer to 'what is roof replacement' is the process of completely removing and replacing an existing roof on a home or building. This typically involves tearing off the old roofing materials, making any necessary repairs to the underlying roof structure, and then installing a brand new roof system from the ground up.
Roof replacement is a major home improvement project that is often necessary when an older roof has reached the end of its lifespan and can no longer effectively protect the home. It is an important investment that can improve the appearance, energy efficiency, and overall value of a property.
