Hello people of I REPAIR, I have the roof of my house with leaks, 20 years ago that the aluminum membrane is placed, I would like recommendations of what to do not to have to change it, I know that there are paintings but I do not know if they give results. From already thank you very much

Hello, you should remove the entire membrane placed. Surely it is stuck on the edges but in the middle it is loose and that is a safe path for water. Once the membrane is removed, clean everything with muriatic acid lowered in water. 30 of acid 70 of water. That removes all fungus or verdin from the ground and together. If you can remove everything after the acid, with the pressure washer clean deep. Let dry very well. It also tries to do everything in an emanate of good weather. If it makes warm or not, it is indistinct. The issue is that it does not rain and there is wind. Then look at the grooves and cracks. Fill them with melted pitch and spread with a spatula. The best option is high traffic asphalt paint. There are different colors. I recommend the one that is red. It gives greater contrast to the places that need to be applied. Two hands is enough. Remember that you don't have to add anything to the paint and apply it with a roller.
