Not Sure If Your Roof Needs Repairing or Replacing?
Fewer things in life can be more frustrating than listening to the slow and constant drip of water emanating from the roof. In these cases, there is obviously some sort of roof damage, but finding the source of the leak needs a lot of deductive reasoning powers. Before you contact a roofing contractor, it is a good idea to check the flashing on your roof. This is sometimes where some leaks occur, and should this be the case, the roofing repair can be quite easy. New flashing can be screwed or glued in place, but the seals could need to be taken off, and new caulk or cement put down first.
The flashing is found at intersecting points on the roof, in places like the peaks and valleys where water will collect and pool. It can be made from galvanized steel, aluminium, copper and vinyl. You can also locate it under shingles running across the peak of a roof, and also chimneys, vent pipes, and even skylights. Flashing is usually used on any point the roof has a dramatic angle change. When installed correctly, it stops any leaks coming from these areas, however, age, time, or the weather could damage it.
The first thing to do is find the flashing, lifting some shingles if needed to see if any of the nails keeping it in place have come away and left a gap. If this is the case, the material can be re-anchored, but hammering in new nails is not the best repair. A better way is to screw flashing down, matching any screws to the same material the flashing is made from . Cover the screws with a silicon seal, thus making it waterproof.
Flashing that is found around chimneys and vents is another story altogether. If it has pulled away, it is because the seals holding it down have rotted or have been broken. Chip away all the old seals, thoroughly clean and remove any debris, and use either caulk or cement as required. Reinstall the flashing and hold it in place until the sealant has cured. However, any other roofing repair jobs that need done are best left to a professional roofing contractor.
