    Oh, no. Imagine it, applying cement all over your roof? Did you see the can
    he used – how rusted the top was – did he leave it our all winter? If so,
    it’s useless. People – don’t do this. Just don’t! I’ve found skylights that
    were patched like this. Do you know, all the cement ruined their skylight?
    We had to remove and replace one – along with a significant portion of
    their roof decking – it was…a…nightmare. Doing a repair like this will
    only cost you more in the long run. Call an expert, please? You want your
    family to be safe, don’t you?

    The best thing to do is always hire a professional roofer to repair your
    roof or you will be doing ridiculous things in an attempt to make an
    improvement and you will create a repair that will not last and that will
    create water traps such as illustrated in this attempt at repairing a roof.
    Also if the shingles are so old that they are cracking all over you should
    be considering a new roof because you have more leaks than that one that
    will only lead to further “preventible” damage such as wood rot in the
    areas you are unaware of the leaks. Always protect your investments and
    hire a licensed contractor for whatever the trade is.

    That house is in trouble. Those vertical rips are the direct result of an
    un or under ventilated attic. Rip it off and do proper ventilation or this
    roof will look like that in short order while growing mold and mildew
    inside the house..

    A repair is usually a temporary fix. We no longer repair with asphalt but
    replace the damaged area with new material.

    There are 2 ways to find a leak, 1 is to use a garden hose and have someone
    inside to let you know when the leak is located.
    The 2nd way and the best, is to get into the “attic” and look for water
    stains.
    I hope this helps (etheromlet) who asked this question.

    That’s exactly how you don’t suppose to a repair,
    What u did was a “patch”
    A repair consist on removing carefully existing damaged shingles and
    install new ones

    The idea is sound but using your HAND instead of a trowel is hilarious! All
    you end up doing is wasting product, ruining your gloves and you lose
    product consistency throughout the patch. ALWAYS use a TROWEL!! It also
    looks a hell of a lot more professional after you’re done..

    When it’s cold (35 degrees) the cement is very hard to apply to the roof
    with a trowel. I couldn’t get it to adhere to the roof well until I worked
    it in with my hands. I made sure to warm up the cement before working with
    it, but I still had a hard time with the trowel. As for the gloves, make
    sure you use disposable/cheap ones that you can throw away afterward. I use
    a old pair of brown cottons. If you can pick a warm day then use a trowel
    otherwise I recommend using a old pair of gloves.

    I used fiberglass roof fabric made by Gardner, It came in a 6” by 50′
    roll. Ask for roof patching fabric at Home Depot. They should know what you
    are talking about. By the way I also used Gardner Wet-R-Dri roof cement.

    how the heck do you find the leak? I have a leak in my living room. its a
    vaulted ceiling with a small leak between two of the wood boards. Ive been
    on the roof and it all looks the same! I cant see any abnormalities on the
    roof.
