Permanent treatment method for roof leakage

What are the permanent treatment methods for roof leakage? What are the good solutions for roof leakage

1. If there are small cracks on the roof, cement mortar or sealant can be used to repair the gaps. After the repaired area is dry, waterproof coating can be applied to prevent water leakage.

2. If there are large gaps on the roof, first clean the cracks and then repair them. It is necessary to choose high-quality polyurethane waterproof coating for painting, and the width must exceed 20 centimeters when painting. This can make the waterproof and roof adhere more firmly. It should be noted that it should not be soaked or rained within 12 hours after painting.

3. Waterproof membrane can also be used to repair leaks on the roof, such as polyester tire waterproof membrane, which has better repair effect and is relatively affordable, and most people can accept it. Firstly, clean the base surface of the roof, then apply base treatment agent, and finally lay the roll material. The thickness of the laying should comply with relevant regulations, and the construction should be standardized. The laying should be carried out in multiple layers, and the joint positions should be staggered. Use a spray gun to continuously heat the connection between the base layer of the roof and the waterproofing membrane. When the heating position melts, you can roll the membrane while heating. When the roll is laid to the edge, it is necessary to seal the edge. Heat the joint of the roll with a spray gun to make it firmly bonded, and use visible asphalt to seal the edge position.

If the roof has a large area of water leakage, it needs to be re waterproofed. First, clean the base surface of the roof and level it. For areas such as the roof drain and corners, special treatment with mesh cloth is required. The next step is to apply base course treatment agent or waterproof coating. The waterproof coating can be exposed asphalt. This waterproof material is processed by multiple processes, with a thickness of 3-5mm. It has good waterproof effect, anti-aging, strong adhesion and other characteristics, and can be closely bonded with the roof. It is a very good waterproof material.
