Finding a roof leak and determining its causes

“Roof leak” is the most dangerous and threatening word for a homeowner because it is really very difficult to track down. Repairing a roof leak is never as tedious as finding the actual location in the roof. Once you find out the true origin, you can easily fix it.

If you ever find water stains on your ceiling or water stains on the walls, it is most likely a roof leak. Water must have seeped away from somewhere and spread over the entire roof. The next step is to find out this leak so it can be repaired immediately. Well-known companies like Roofers Ann Arbor Michiganetc. can be of great help in this regard. Here we have also worked out a guideline for you on how to find a leak in the roof.

How to find a roof leak

When you start tracking a leak, always look uphill from the stains to the roof. The most important thing is to look for penetrations on the roof. The most common source of leakage is objects, particularly water, entering through the penetrations. If the shingles are not broken, leaks will rarely develop, no matter how old the roof is. There are several types of penetrations in a roof, including plumbing, roof vents, chimneys, dormers, or anything else that protrudes through the roof. In addition, the leaks can be several feet above, to the right, or to the left of the penetrations.

Fortunately, if you have attic access, your best bet is to bring a flashlight and look for evidence. You will find some water marks, black spots, or mold around the problem area. If you don’t have attic access or you have a vaulted ceiling, don’t worry.

Now all you have to do is go up to the roof to investigate the suspects. If the leak is not detected this way, take your garden hose with you on the roof. Start soaking the suspicious areas one at a time for a sufficient amount of time to allow a drop to drip down the ceiling.

It can take about an hour to locate the leak this way. So you have to be patient enough. Have someone around the house where the leak occurs and ask them to tell you about the drop. If this trick doesn’t work either, remove the shingles in the suspicious area. This is where you need to find the evidence of a leak and get to the source by tracking down the evidence.

Technical causes of roof leaks

There can be several causes of roof leakage, but the main ones are the following.

Lightning is a waterproof barrier in the form of thin pieces of metal that are attached under shingles and at the roof joints. These lightning bolts can remain hidden or exposed. When they are hidden they have a rubberized coating over them. When exposed, they take the form of long metal runs. The metal parts of the moldings are often sealed with tar by roofers, and these parts can corrode over time. Over time, rain and wind have a very strong effect on the lightning bolts and they become broken and cracked.

Since shingles are the outer layer of the roof, they are really very easy to spot. You can identify missing shingles by observing different colored stains on your roof. Storms, strong winds, heavy rains and storms cause the shingles to collapse. They can pollute your garden after the heavy storm.

  • Valleys may not be properly sealed

A valley is an area where two levels of a roof come together. Rainwater can enter through the sloping valleys if they are not properly sealed. The leakage problem of this type can be identified by searching the wet spots along the roof seams. The main reason for this is the poor cover from the beginning or the erosion caused by excess rain or ice.

There are left roof vents like small pipes that protrude from the roof and are designed to drain excess moisture from the inside. If something leaks from here, corresponding dark spots are created or left behind. Roof vents are often sealed by placing lightning bolts around the opening. In addition, a sturdy rubber boot is slipped over the point where the pipe protrudes from the roof. These lightning bolts can break or the roof can deteriorate over the months.

  • Building an ice dam

An ice ridge often forms at the edge of the roof, preventing the melting ice from flowing off. The roof is damaged by the combined weight of the ice and the water already sitting there. When the snow melts, the water flows between the roof surface and the snow and freezes into ice when it settles on the outside edge of the roof.

Your roof’s drainage system is designed to drain the rainwater. When the gutter is clogged, this drainage stops. The rainwater collects in the form of a small basin and begins to seep through cracks and become a leak.

The area around the top of the chimney often shows signs of wear along the mud cap. A cracked chimney can create holes in the mortar joints that connect the chimney to the roof. Mortar, a thick mixture of water, sand, and cement, erodes easily in acute weather conditions.

  • Skylights not installed properly

At the time of installation of the skylights, gaps or penetrations may be left on their sides. Improper measurement and installation of the skylights will leave these gaps. In addition, the insulation on the skylight edges will deteriorate over the years and there will be leaks.

These are some of the technical causes of roof leakage that need to be shared with others for better awareness and recovery.
