A friend of mine gave me a gallon of the Liquid Rubber he had left over after I complained to him about a chronic leak on my roof. Although my roofer did some patch work, I still had water coming in when the rain was heavy. Well I tried the Liquid Rubber in the area where the water was coming from.
That was six months ago. Today, all is dry. I have to thank my friend for introducing me to this great product.
