How Do You Find A Roof Leak

Your Valleys Arent Properly Sealed


What Does It Look Like: An area where two planes of roof come together. Since, these areas of the roof are usually sloped, if the valleys are not sealed together properly, rainwater can get inside as it runs down the roof. You can detect a problem by searching for wet spots that run along the seams of your roof.

Why It Happens: A variety of reasons the sealing may not have been done properly in the first place, it may have cracked when being stepped on, or an excess of rain and ice may have caused it to erode over time.

How To Fix It: This is one of those things that needs to be done by a professional because of its complexity and we do not recommend attempting it on your own. However, your roofer will likely fix the problem by laying a new leak barrier along the valley and shingling overtop.

Collar Failure Around A Gas Vent

A gas vent is a metal pipe with a cap on it that comes through the roof. These are incredibly important because they make sure any carbon monoxide coming from gas appliances vents out through the roof.

Most of the time these vents are installed by HVAC workers after the roof has been completed. However, they arent trained properly on roofing techniques. Theyll slide a collar over an unsealed pipe and flange thinking it will shed the rain right off of it.

Under normal circumstances, this works. But with a torrential downpour, water can splash under the collar and lead to water running down the pipe.

Use A Hose To Pinpoint The Leak

Roofing – How to find a roof leak

Some leaks may be so small that its hard to see them with the naked eye. To find those leaks, you may have to simulate rain.

Ask a friend to stay in one of the rooms closest to your homes roof. Now, run a garden hose up the ladder carefully. Now that youre on the roof with the hose, ask another friend to turn the water on. Keep it to a low flow because you dont need that much.

You can now start soaking specific spots along the roof with water. Soak each spot for about a minute or two then ask your friend in the room if water is dripping. If no water drips through, move to another spot and continue what youre doing.

Eventually, water will fall through the roof and thats where you need to check for the leak. You can mark that spot and continue with what youre doing if you suspect that there are other leaks. After finding the leak, you can patch it up if the damage is minor. More serious damage will probably require the services of a roofer so just cover up that spot for now.

What Do You Need to Know About Finding And Fixing A Roof Leak?

As with any project, there are steps to be completed. Lets explore the best ways to find a leak in a roof without an attic:

  • Check for water stains on your ceiling
  • If you have tall ceilings, check for stains at the highest point.
  • Locate the stains in terms of the slope. Smaller stains that are higher up the slope than the bigger stains are usually where the water penetrates through the roof. This shows water has entered and travelled down the slope creating a pooling and larger stain towards the bottom.

  • Always wear rubber-soled shoes that are nonskid.
  • Find the area where you suspect is the leak location.
  • Check your flashing on the vents and chimney for damage.
  • Check your shingles in the suspected area for moss and if they are loose.
  • Use your pry bar to lift up your shingles. This allows you to check the roof decking underneath.
  • You will see rotting wood and damaged tar paper if there is a leak.
  • If nothing is discovered, use your garden hose to soak the shingles in small areas.
  • Have someone inside the home to see if any water stains or dampness shows up on the ceiling.
  • Make sure you dont flood the roof. Complete this task in small areas until you are sure to have located the leak.
