Roof leaks can be cause by missing shingles, gaps in the metal flashing around chimneys and vent pipes, or small holes in the roofing. The source of a leak often isnt obvious on the roof itself, and it can be hard to pinpoint, since the water may run down the roof decking and rafters before dripping onto the ceiling below.

To locate a hard to find roof leak:

  • Go in the attic with a flashlight, during or shortly after a heavy rain, being careful not to step through the ceiling. In the absence of rain, use a garden hose to thoroughly wet down the roof to create a manmade leak.
  • Examine the roof decking and rafters in the attic above the spot where the ceiling is wet.
  • Follow any water stains or wet spots up the rafters or roof decking to their highest point.
  • Measure down from the roof peak to the highest point of the leak and over from a gable end to the leak.
  • When the roof is dry, go on the roof, and transfer the measurements to the roof, allowing for any overhang on the end of the roof.*
  • Examine the roofing closely for signs of the leak at the location you measured.
  • If you cant see the source of the leak, continue to look higher up on the roof, since water can run down behind the shingles before emerging in the attic decking or rafters.
  • *NOTE: Take all safety precautions when positioning ladders and climbing on a roof, and do not attempt to go up on a steep roof.

    How To Spot Early Signs Of A Roof Leak

    These early signs of a leak should help you find both the source and the severity of a roof leak or potential roof leak. Here are some of the tell-tale early signs of a leaking roof.

  • Water stains on your ceilings. As water leaks into your attic, it can saturate through your insulation and attic floor to the point of reaching your upper floor ceilings. These stains can occur very quickly, depending on the severity of the leak or slowly over time. Either way, if you spot any wet spots or stains in the corners or along the edges of your ceilings, chances are you have a roof leak. It can also be poor ventilation that causes moisture build-up in the attic, but it shouldnt be ignored either way. Note: Water stains around chimneys can mean the roofs flashing has lost its integrity and needs to be replaced.
  • Rotted beams and moldy insulation in the attic. These are obvious signs of a leaking roof and can be detrimental to your homes integrity and health. Rotted wood becomes a structural issue then and requires a much more expensive and extensive repair. So checking your attic before you see those interior signs of a leak can save you the pain of such damage.
  • Look For Warping And Discoloration

    How to find RAIN water leaks behind your walls….

    If you wait until water is actually dripping into your home, the leak in the attic will have progressed to a point that requires serious repairs. So, instead of waiting for that to happen, periodically check for any warping or paint discoloration on your ceiling. Dripping water will cause white paint to turn to a yellowish brown color, or may even cause the paint to bubble up.

    As soon as you notice any changes to the paint on your ceiling, get up in the attic and search for the leak. Youll still have some repairs to do, but theyll be much more less expensive than they could have been if youd waited for the water to seep through the ceiling.

    Check The Attic Regularly

    Of course, its even better to catch the leak before the warping and discoloration begins to occur. The best way to do this is to get up into your attic on a regular basis and look for any leaks. While it may not be pleasant to climb up into your attic, it doesnt have to be done very frequently. Simply examining the space with a flashlight twice a year should help you to spot any water that may be coming inside.

    Its best to do this during or immediately after a rainstorm, since its much easier to spot an active leak than to find traces of dried-up water in your attic.
