I reside in a 15-year-old flat. The roof covering is 1400 sq.ft. of my house. It is a black rubber membrane.It has never been kept up with so there are some cracking and leaking. I already went up and repaired the spots with fibered roof cement, but now that it is getting warm and I want to coat the whole thing to seal it all off. What particular kind of coating should I use? I have decided to go for a professional roof repairing service
. Could anyone here suggest me some methods that you are following to avoid cracking and leaking of the roof? I am really fed up.
