This home in Knoxville, TN with leaks is in need of a new roof. This is a dimensional shingle roof that is about twenty years old. The customer has had various leaks throughout the home. There have been many leaks in the garage. There is a ridge over the garage where it is obvious that water has been getting in under the shingles. Many of these nails are showing rust. The chimney flashing on this home will need to be redone and there will be a section of wood that will need to be replaced at the bottom of the chimney. The wall over the garage also only has partial flashing so this most likely the cause of many of the leaks in the garage as well.

Various Leaks Throughout The Home

  1. 1
    Missing Flashing At This Wall

    This wall is right over the garage and it definitely has flashing missing which could definitely be the cause of leaks. It appears that only the top five shingles have step flashing while the rest do not. It is important to have step flashing at every shingle to prevent leaks.

    Nail Pops And Old Repair Attempts

    When you pull up the shingles, many of them have rusty nails underneath. There is water getting through under the shingles and causing leaks inside the home. The roof also has various nail pops that are easy points for water to enter. It looks like there has been attempts at repairing the roof with roofing cement but it is no longer sealing the shingles.

    Chimney Flashing Needs Work

    The chimney flashing on this roof needs work on both the upper and lower portions of the roof. The top portion of the roof has shingles bunched together. With these shingles bunched together like that, the shingles are not sealing correctly and allowing water to get in under the shingles. At the bottom of the chimney, the nails under the shingles are rusty and the wood underneath feels soft. This section of woof will need to be replaced.
