7 Roof Repair Tips: Find and Fix a Leaking


Roof leaks are one of the common occurrences especially in older houses and in environments prone to water damage. Some homeowners may not realise this problem exists until it is too late and everything has been damaged up there. If you see water stains extending across ceilings or running down walls, chances are you are having a roof leak.

The hardest part with roof leaks is how to track them down. Once you succeed in this, repairing them is not as difficult. Below are some 12 tips on how you can find and repair roof leaks in your home.

Finding Roof Leaks

If you suspect a roof leak, you should first identify any roof penetrations. There are several items that can penetrate roofs and these are classified as the major causes of leaks. Penetrations in this case may include roof vents, dormers, chimneys, and any other items that project through the roof. If your house has attic access, simply climb up with a flashlight and check for any evidence such as mould, black marks, and water stains.

Difficult to Find Leaks

If your leaks are hard to find, a roof repair Perth professional can go up the roof, soak the area above the leak and wait for the drip to appear. You can also run a garden hose for a few minutes to check which areas of your roof are dripping.

Identifying Small Leaks

Sometimes, water drips far away from the spot where the leak is actually is. This mostly happens in ceilings with a plastic vapour barrier between the attic insulation and the drywall. Pushing this aside and checking for any flow stains on the plastic can help you locate even the tiniest leaks.

Plumbing Vent Boots

Depending on the materials used during your home construction, your plumbing vents boots may be made of plastic, metal, or a combination of both. The plastic bases may at times crack and the metal seams may open up or break. Examine the rubber boot around your pipe and where they seem own out, broken, or cracked, replace them immediately.

Fixing Roof Vents

When your metal or plastic roof vents are cracked, the only option is to replace the damaged vents. While there, check for any missing or pulled nails and replace them with screws. If you can remove the nails without interfering with the shingles, the better.

Fixing Walls and Dormers

Instead of coming in at the shingled surface, rain may come in from above the roof particularly if it is wind driven. Areas of entry may include cracks in siding, windows, and in between corner boards. Also, dormer walls may provide entry points for water to dribble down and penetrate the roof.

The best way is to dig around using a knife and check if the area is properly sealed. Any caulk you suspect should be replaced with new siliconized latex caulk and any cracked sidings overlapped by new pieces.

Fixing Step Flashing

In most constructions, step flashing is used on walls intersecting the roof. Every section of flashing helps in channeling water downhill over the shingle. With time, flashing may rust or loosen thus making water to run behind it into your house. Any rusted flashing should be immediately replaced.

Remember you can stop roof leaks yourself, you only need to know how to do it right.
