Roof Leaks In Heavy Rain

Imagine sitting at home on the couch and you are in the middle of your favorite tv series. While watching the series you start to notice a few water spots on your ceiling and realize that you have a leak during the rainstorm. Heavy rainfall can often overrun your gutters. The gutters could be clogging or just not allowing the flow of rain quick enough. When this happens the water will sit on the roof and potentially seep through the shingles. This exposes the weak spots of the roof.

Are you wondering what to do when the roof leaks in heavy rain? Locate and identify the leak, assemble the materials needed, and install the replacement pieces. However, it is always best to call a certified professional. This is because climbing on the roof is dangerous and you also want to make sure the repairs are done correctly.

What To Do If The Roof Leaks In Heavy Rain

The rain has started to come down and you notice dripping from your ceiling. Your first thought is, what do I do now? Panic is the last thing you should do. Although this is a minor inconvenience due to the fact that your roof is assumed to be in good condition, your biggest concern should be to minimize the water damage.

Taking Care of the Roof Leak During the Storm

  • Add a tarp– if you know where the water is coming in, add a tarp on the outside of the roof to cover the area. You will have to weigh down the tarp with cinderblocks or bricks.
  • Grab a bucket – put a bucket under the leak and cover up the furniture. If you can, move items out of the way. Use a towel or a mop to dry up the floor and warn family members of the water.
  • Try to find the rain leak – look around to see where the water is coming in. You may want to take a picture of where the leak is so you can let a roofer know. You also want to take pictures of the damage for insurance.
  • Go in the attic – take a look around the attic for drips or issues and you may be able to find the source. If you can fix it from the inside, that is great! If not, contain the water and contact a roofer as soon as possible to fix it.

Finding the location of the leak during a rainstorm can help you minimize the damage. It is not suggested to get onto the roof during heavy rain, but if you can find the location on the roof that has the problem, you can substantially reduce the damage.

Why A Roof Leaks

Let’s consider that there are a variety of reasons why your roof leaks in heavy rain. You might consider the following:

  • Chimney – there could be a leak in the counter flashing that you want to have checked out.
  • Plumbing – there can be pipe bellies and cracks in the pipes.
  • Skylights – there is a seal around the skylight that might need replacing, dirt in the track, or high humidity.
  • Metal Corrosion – reduces water flow through the supply lines
  • Degraded Shingles – sometimes shingles will start to deteriorate and if this happens, they need replacing. Maybe you covered your shingles with metal and the material underneath is leaking. It will be important to have the area inspected.
  • Condensation – attics are not always the best ventilators and condensation can collect on pipes that go through the attic. When the attic is having difficulty taking the hot air out and bringing the cool air in, an attic ventilation fan may be needed.
