Over the years, your roof may have developed some leaks. For a shingle roof, leaks may be caused by cracked or missing shingles or shakes. For flat roofs, the leak may be caused by a blistered or cracked area. Locating the cause of the leak is what the tricky part is. If the damage is not evident, a roof repair professional should be called in. When doing repair work yourself you should take some necessary precautions to prevent injury:
- Do the work on a sunny day as the roof would be completely dry and not slippery from rainfall
- Use safety ropes and rubber-soled safety shoes with good traction
- For steep roofs, use a ladder framework
- Avoid handling, touching the power lines while on the roof
When investigating the marked leak point, look out for any damaged, curled or missing shingles. Look for breaks in the flashing or caulking. Check at the place where two surfaces meet and around the chimney or vent. If you are unable to detect any damage, call in a professional roofer. Torn, rotten or missing shingles should be replaced. If a whole area of shingles is damaged or missing the whole roof may need to be re-roofed. A variety of materials like natural slates, tiles, Eternit and pan tiles are commonly used for roof repair cost.
Traditionally shingles were made of wood, but can also be made of materials like asbestos-cement, bitumen-soaked paper covered with aggregate (asphalt shingle), composite or ceramic. Wood shingles and paper based asphalt shingles are less commonly used as they present a fire hazard, and fibreglass-based asphalt shingles have taken their place. Tiles can be made of ceramic material. Being hard and brittle they break easily when tree limbs or other falling objects damage the roof, but they are not subject to deterioration from rotting.
In some instances your roof may be fine but you could experience something like leaks.
Ice Dam leaks block the natural flow of the water down a roof, the water then begins to back up under flashings, shingles, tar paper etc. The water may drip into the house for days. The only precaution against t his condition is to install membranes under the roofing. This will help stopping the water leaks.
Wind is often the cause for leaks as it may drive water up and under your roofing materials. Roofing cement under the shingles may arrest the leaks. Another reason for freak leaks is attic condensation from high humidity. Get a professional to assess your roofing. Residents can consult trained professionals for their specific needs.
