How do I stop my roof from leaking in heavy rain?

You can use sealant, POP, and other roof leak and damage restoration materials to stop the leak during the rain. You must remember that you will have to apply these materials to the roof surface present inside your home. However, you can put plastic over the roof where there is a leak because sealants and POP will not be effective during the rain when you will apply them over the roof leaking area.
