The most common areas a roof leaks, and how to repair them.
Any visible evidence of rook leakage, such as water stains on the ceiling, is an immediate concern for the home owner. Above the water stain, you are likely to find mold, rotted framing and damaged insulation among other problems. This is why experts recommend routine inspections of the roof and attic once a year and after extreme weather events. Whether you spot a leak early or late, knowledge of the common areas leaks develop and how to repair these will save you time and money.
There is no need to inspect every inch of your Miami roofing system during the search for a leak. Start with the part of the roof above the damage. Keep in mind that leaks can develop on open areas of shingles or other materials, but this is far less common than another type of leak. Water penetration is most likely to occur where the roof is already penetrated, such as chimneys, vents, plumbing, dormers and other items.
Other common areas include anywhere the roof meets a flat wall, the roof changes direction creating a “valley,” or flashing is visible. Most leaks can be positively identified with a garden hose and inside helper. Start at the lowest point of the suspected leak area, and slowly work your way up until the helper sees water penetration.
Leaks can result from damaged flashing or other roof materials, poor flashing installation, exposed shingle nails and/or poorly trimmed shingles in a roof valley. The problem needs to be corrected immediately, and quick fixes are generally not a good idea. If you happen to see roof membrane used for repairs, caulking, or roof cement during a visual inspection, you’re looking at potential leaks. The owner should be prepared to remove and replace damaged parts, including any already existing water damage. Minor repairs can be often be handled by the property owner, however if the problem is severe and continues to persists, it is always best to contact a professional contractor such as Miami Roof-Tech to resolve the issue for you.
