They will be able to identify the extent of your roof leak and provide repair estimates. If you don't see any signs of moisture, use the flashlight and look for dark or bright spots, which are sometimes more visible under a flashlight. Then turn off the flashlight and any other lights in the attic for a moment and look for bright spots from the sun outside. If you can see any light coming through the roof (other than light coming through the roof vents), that space could be the source of the leak.
In most cases, you find out about a roof leak when you see a water stain on the ceiling. To locate the source of the problem, go up to your attic and try to overcome the stain on the ceiling. One way to check for leaks is to run the garden hose through the roof and see if drops enter the interior. If you have an attic, the easiest way to detect the leak is to go up there on a rainy day.
The water will reflect the light, so bring a flashlight. Once you locate the source of the water, mark the area. On a good day, ask an assistant to touch the mark while you're on the roof. After determining the location on the outside of the roof, apply new roofing cement or shingles as needed.
Therefore, you need to find the leaking roof area and repair it quickly before even more damage occurs to your property. However, if you are not comfortable on the ceiling or if the leak seems extensive, do not hesitate to contact a professional. Water usually enters through worn, broken, or missing shingles; where nails have loosened; or through corroded or poorly sealed roof flashings around vents, skylights, or chimneys or along intersections of the Looking over the roof leak is a good start, but also you'll want to check near common areas where water can collect on the roof, such as corners, where roof joints meet, or near roof features, such as skylights, valleys, and chimneys. Once water passes through the ceiling, it flows along the siding, ceiling beams, or the top of the ceilings until it finds a place to inevitably drip onto your favorite piece of furniture.
Roofing experts will advise you to “think like water” when looking for the source of a roof leak; know that water usually enters through broken or overgrown shingles, missing tiles, poorly sealed or corroded flashings around chimneys, skylights, ventilation grilles, or along the intersection of different planes or points where the nails are loose or missing. If you can't find the source of your roof leak, but you still see evidence of a roof leak and water ingress, or if you don't feel comfortable looking for or fixing the leak yourself, it's time to call a roofing contractor. After all, water travels downhill from the point where it enters the roof, so the actual hole or leak could be much higher in the ceiling plane. You may also want to review your roof warranty and also consider your insurance coverage and how the policy is worded with respect to repairs you can perform yourself rather than repairs done by a professional.
A roof leak can be difficult to find, difficult to fix, and even scary for homeowners and property owners, as physical condition can jeopardize the livability of their property. Infrared cameras can show you evidence of the ceiling leak, but they may not tell you what caused the leak. You know that the roof is bad if tiles are missing or obviously damaged, or when water stains the ceiling or walls. If you can't find the cause of a leak in the attic or by visual inspection of the roof surface, wait for dry weather to arrive and ask a friend to help you do a water test.
If the leak isn't caused by premature roof failure, your roofing contractor can make repairs to give your roof more life. .
