    Locating The Leak For A Flat Roof Leak Repair

    Discovering the source of a leak in a flat roof is usually easier than finding one on a sloped roof or a shingled roof. That said, roof leaks of any kind can be more complicated than they initially seem especially if youre an amateur trying to DIY roof repairs.

    There are many reasons for this, starting with the fact that the spot where you initially notice water entering your interior rooms might not actually be where the leak itself is, since water that penetrates the membrane of your roof can travel across the roof until it reaches a seam in the sheathing/roof deck, skylight or electrical, HVAC or plumbing penetration and then manages to drip or seep through to the inside.

    Nonetheless, there are steps you can definitely follow to determine the source of the leak , whether or not it is easy to find or readily evident when you first notice the water entering your interior.

    I Need Help With Leaking Porch Roof

    I hope someone can give me some guidance. My back porch is leaking quite badly. The roof appears to be made of metal, with wood placed on top .

    Ive included pictures of what the porch looks like from the inside, and what it looks like from the outside. The major leaks are where the tape is — during heavy rain, I have to place receptacles there to catch the rain. The leaking is toward the front end of the porch, away from the house. At the point where the porch attaches to the house, it is completely dry, with no leaking.

    At one point the house was vacant and the porch was covered with overgrown vines. From an old picture, I can see that some of the vines may have come through the ceiling. However, I cant see from the photo whether the vines actually broke through ceiling or entered from the sides .

    Someone suggested to me that it is likely that the wood on top of the porch roof has allowed debris to collect underneath forming a dam. He thinks that when it rains water dams up and works up around the joints in the metal ceiling. He said that without the wood on top most gunk on the roof would naturally wash away with heavy rain.

    I need some advice on how to address this. I dont know whether it is possible that the vines broke through the joints of the metal roof and, if so, whether that could be repaired or re-sealed somehow.

    Use Roof Flashing To Temporarily Cover The Leaking Area Of The Roof

    Roof flashing is a flimsy metal material that can be caulked under shingles over leaking areas. The flashing allows water to run over the area without being able to get into the house.

    All you have to do is apply caulk around the location of the leak, tuck the flashing under the row of shingles, and press it against the caulk, which will seal it from leaking.

    Flashing can be very effective at stopping leaks around the base of the chimney or in parts of the roof where the most water will drain to. Professional contractors will usually install flashing when the roof is originally built in order to ensure the longevity of the roof.
