Leaking roof should do this!

First find the reason
1. There is a problem with the floor structure. It may be due to age, and more likely to be due to quality. The roof leak caused problems during the use of the floor, thus causing water leakage.
2. The house is old, the residential house is too long and the maintenance and maintenance measures are not well done, and the roof waterproof layer material of the house is aging or damaged, then the house leakage is also a normal cause.
3. There are reasons for roof leakage caused by pipes. As each floor has to be connected with pipes, perhaps because the pipes and the floor touch area are not closed sufficiently, the roof leaks.
4. There are many small cracks. Roof leaks are basically caused by cracks in the roof. Small cracks are the most common in roof cracks. They are also the most common and main reason for roof leakage.

Next choose materials
1. The material has good weather resistance (can withstand the test of weather), and has certain endurance to light, heat, ozone, etc.
2. The material is resistant to water penetration and acid and alkali.
3. It has a certain degree of adaptability to external temperature and external forces. The material has a high tensile strength and can withstand temperature changes and deformation caused by various external forces and expansion and cracking of the base layer.
4. Good integrity, which can not only maintain its own cohesiveness, but also firmly bond with the base layer to form a stable and impermeable whole.

Last look at the steps
1. Primary treatment
Check the quality and dryness of the leveling layer and clean it, and apply the base treatment agent after meeting the requirements to ensure that the size of the painted area can meet the construction needs of the day. Coiled material can be applied 4 hours after painting.
2. Construction process
Cleaning and repairing the surface of the base layer → brushing the base treatment agent → additional enhancement treatment at the node → positioning, elastic line, trial laying → laying of coiled material → closing treatment, node sealing → cleaning, inspection, trimming → protective layer construction.
3. Construction sequence
4. During the construction of the waterproof layer, the joints, additional layers and roof drainage areas should be treated first, and then the construction should be upward from the lowest elevation of the roof. When laying gutter and cornice roll materials, it is advisable to follow the gutter and cornice direction to reduce overlap. During the construction, the construction shall be carried out according to the principle of first high and then low, first far and near.
