Roof repairs for leaks from cracked roof tiles?. If you can hear water dripping inside your roof from a roof leak, or its starting to drip from a nail in the plaster ceiling, or if a roof leak stain is starting to form on your ceiling it’s really important to drill a hole in your ceiling to let the water through especially if there is a heavy rainstorm. You can do this easily with a screwdriver or an implement from your kitchen but be careful! This stops the roof leak water from spreading across the top of the plaster ceiling to other areas and just might stop your electric lights from fusing. Roof leak water from a tiled roof is usually a dirty brown colour so its easy to see if it’s a roof problem or another type of plumbing issue. Roof leaks can start from cracked tiles but also roof skylights and roof flashings that might be corroded have started to leak.
