Roof Valley Repair Techniques

Roof is the second sky for us. Roof valley repair techniques fix problems in this critical seam area. A roof valley is where two roof surfaces come together, such as in the inside corner of a roof on an L shaped building. With asphalt shingles, this area can be covered by interweaving the shingles at this juncture, but this is somewhat complicated, so many roofers use a metal valley which is a wide v-shaped piece of flashing. Installed correctly, roofing felt is interwoven across the valley, then a sheet of ice and water shield runs down the valley. This product seals against nail punctures. The metal valley is put down after this and before the shingles. Installing roof valley is tricky and this is the most common area for leakages. You need time to time repairing of the roof valley or it can cause a great damage to your roof.
Most roofing materials are installed starting from the bottom edge of the roof and the next layer goes on top, moving all the way up to the ridge. This way water drains off the first top piece and flows down onto the next one, down to the gutters. On an inside corner, twice the volume of water is coming down. During large rainstorms, water from one roof can run under the shingles of the other roof.
One of the things that make you think you need to repair the valley could be caused by buildup of plant life. People rarely look up at their roofs, but inspecting it personally, in the spring and fall, and especially after storms is a good idea. If you havent cleaned your gutters out and have maple trees by your house, you could have a mini garden growing in your gutters. In a valley, this can cause a mini dam to build and water behind it will go beyond the width of the valley and work its way under shingles. So be aware of it and regularly check your roof. Roof valley repair techniques are best left to professionals, but gutter cleaning can minimize your difficulties.

    Can anyone tell me the names of the materials that are needed for a flat roof repair job?
    I need to repair a flat roof but I don’t know the names of the materials I need. If anyone does can you please tell me. It is a tar roof. Thanks

    • ANSWER:
      Actually this is a far too complicated question for this format.
      The question is simple enough,but the background isn’t.
      We don’t know what the problem is (most likely leakage),
      but without more detail it’s hard to give proper advice.
      I could tell you use EPDM ,which is a rubber membrane,
      but that may not be what you need.
      The material used depends a lot on your local climate.
      Sun or snow 🙂
      Local,State and Federal offices have info about the proper construction for a flat roof.
      Tar,while still being used is not an ideal material
      and is superceded by synthetic rubber materials.
      Regardless,your finish coat should always be a white UV resistant and waterproof coating,no matter what is underneath.

      Your best bet is to get familiarized with the process by doing a search – Google or Yahoo etc
      for “flat roof” or “flat roof repair” or similar.
      The next thing is to find an interactive DIY forum,
      such as
      Again do a search for DIY forums.
      This way you have more interaction with the forum members
      and you can accurately describe the location,size and other details of the roof.

    What percentage of a roof repair estimate is for labor vs materials?
    What is the average amount for labor costs?

    • ANSWER:
      There is no average. Too many variables.
