Being able to locate a roof leak on your own is a great way to handle small problems without any professional help. Here are three steps to help you locate the area where the patch needs to be placed:
Use a Flashlight: The first thing you want to do is use a flashlight. Don't use your smartphone light since this doesn't provide enough light. After all, you don't want to spend too much time up on the roof. With the flashlight, climb onto your roof (with the right footwear to prevent a slip and a spotter). From here, you want to check the surface of the roof with the light. This is going to help you spot any hidden holes in the roof's surface. Obviously, all areas where there are holes or tears will need to be sealed.
Get Into the Attic: It can still be difficult to find a leak in the roof just by checking the surface alone, and this is because most leaks are so small that they don't even show on the surface of the roof, but instead underneath it. The best bet at this point is to check the attic. If you notice water build up in one area of the attic, chances are that the leak is located right above that.
Use Water: Obviously you will need to wait for dry weather to get up onto the roof of your home. If you are still unable to locate the leak from here or the attic, then you want to use water. Pour water over the roof and see where it flows. You might notice right away that it is flowing to a certain area of the roof and not making its way down the roof as it should. This is where the leak is occurring. The best way to do this is to use the garden hose to get as much water as possible over the roof. Just cover small areas of the surface at a time to more easily discover where the leak is.
If you don't feel comfortable on the roof of your home or you are still having trouble finding the source of the leak, call in the professionals. They will have the right tools and equipment to patch up the roof in no time at all, so the next time it rains you don't have to fear about water damage in your home.
