Unauthorized modification of the roof caused water leakage, and the property was still in charge.

Hello, generally, the property will not be responsible for the maintenance of the house caused by this private reform. Because part of your house has a sloping roof, you can only suggest waterproofing if you want to solve it. Slope waterproof construction is difficult, with emphasis on construction safety and construction technology, and the tiger window in the middle also needs to be treated. As long as the platform is connected with the sloping roof, it is suggested to treat it with slotted drainage slope to reduce the cost.

There are several calculation expenses: the cost of laying coiled material on sloping roof+waterproof and closed construction of skylight+slotting and drainage construction. Among them, the calculation of sloping roof area generally needs to multiply the plane area by the slope coefficient.
