Common Causes Of Flat Roof Leaks

Unlike slanted or sloped roofs, flat roofs don't have the ability to drain standing water. That means rainfall and any amount of water that occurs will sit on the roof for a longer period of time, resulting in eventual damage.1. Pooling Water

Unlike slanted or sloped roofs, flat roofs don’t have the ability to drain standing water. That means rainfall and any amount of water that occurs will sit on the roof for a longer period of time, resulting in eventual damage. Unfortunately, if the water is left standing for longer than 12 hours, it leads to seepage into the membranes of the rooftop that results in direct damage quickly as a result.

By staying proactive, you can effectively eliminate pooling water. It’s also crucial to unblock drains by removing debris or blockages that may prevent water flow.

2. A Shallow Slope

If your roof has a very shallow slope, the trajectory of wind can damage or remove shingles. This means rainwater can now enter your property. The ratio of a slope is properly measured by placing the vertical rise distance number over the horizontal distance.

If your roof slopes between a ratio of 2:12 or 4:12, you will need to add additional materials to the roof for protection. It’s crucial to ensure that your roofing is installed by professional contractors and the material is appropriate for the pitch of the roof.

3. Blistering Damage

Blistering is when air pockets are trapped under the shingle membranes, leading to undue damage. The problem significantly worsens during warmer days when the sun heats up the roof and causes an expansion within the air pockets.

It’s important to constantly check your roof for blistering and repair the damage before it becomes severe enough to impact the membrane. Contact the experts for bay window roof repair. Blistered materials need to get removed at least five inches above the edge of the damage.

4. Debris

Once again, allowing debris such as pine needles, decaying leaves, and other organic matter to remain on the roof can cause damage to the membranes. It’s also possible for this buildup to cause the gutters and drains to develop a clog, furthering the potential for leakage.

5. Alligatoring

This terminology refers to the surface of the bitumen cracking. The crackling pattern creates skin reminiscent of that of an alligator’s back, hence the term. Debris, water, and direct sunlight are all contributing factors that can cause this type of damage. Without adequate and timely repairs, the cracking quickly spreads.

Coating the affected areas is one way to prevent damage. It’s also a possibility to coat the entire roof, but do make sure to remove any debris buildup first! The application of a primer is also recommended to ensure that the coating uniformly sticks to the surface.

6. Temperature Fluctuations

Temperature fluctuations can cause the expansion and contraction of the roofing materials. This is, unfortunately, a normal occurrence that does lead to natural damage eventually. Thermal movement is another name for this phenomena that can cause the flashing to pull away from the edges of your roof line. As such, water and moisture will seep beneath the surface of the roof.

Good quality roofing materials and proper flashing installation can help prolong the life of the roof. Maintenance is also a key factor in ensuring that damage is prevented! This means that regularly repairing and maintaining your roof are crucial.

7. Missing Shingles

Strong winds and inclement weather can cause shingles to fall off of your roof. These exposed areas can once again cause rainwater to enter the roof’s foundation and cause a leak. The best course of action to take when you notice missing shingles is to simply make the necessary repairs and replacement the following day.

8. Plumbing Problems

Not all leaks are directly caused by the roofing materials. In fact, leaky plumbing pipes that are on the roof along with water tanks can also contribute to the problem. Loose joints or missing sealing thread can also contribute to plumbing leaks that worsen with time. Not only will this cause extensive leaking within the roof itself, but also causes the leaking to affect the walls of the building as well.

When you notice any amount of leaking inside of your property, make sure to find the source of the problem in a timely manner to avoid costly damage. If the problem is directly related to a plumbing issue, make sure to have it addressed by a professional as soon as you can. Perhaps the easiest way of dealing with any amount of trouble is to simply call a trusted local roofing contractor and have them look over your roof to assess damage.
