Noticed last night that the flat roof on the garage has developed a leak. It's about 3m x 4m, and the classic layered-felt construction.
Now my opinion is that there are 2 types of flat roofs : those that leak, and those that are going to leak.
I notice there are a few places on line selling DIY rubberising kits ... has anyone any experience ? Or would I be better off just re- laying some felt with some bitumen ?
