    Default Granules missing on just a few shingles???

    Hi all,

    Granules missing on a few shingles. Is this possibly a manufacturing defect?

    If not what would cause this?

    I would say bad shingles, most likely a flaw from the factory, but the onus is on the roofer to toss those aside. Always a big rush to stay ahead of the nailgun.

    Craze cracking. Kenton Shepard has written extensively about tree tab and composition shingles.
    Likely manufacturing defect.

    I should have believed you....

    Craze-cracking- ....
    - seldom turns into splitting- which is considered functional damage.

    .....

    Eventually, cracks propagate through the mat to form splits. The roof is then at or near the end of its useful life.
    So which is it?

    Craze-cracking seldom causes leaks, because cracks are in the surface layer only. In addition, underneath each craze-cracked shingle is another shingle, usually in much better shape since it hasn't been exposed to weather. (emphasis mine)

    Obvious on what regard?
    Kenton Shepard has written very informative articles for the inspection industry.
    So please inform the members. Who here has written inspection articles on:
    legal issues;
    report formats;
    HG template with his narratives
    data-gathering methods (including mobile reporting);
    reporting software (choosing and using);
    report content;
    report writing time;
    report length;
    narrative writing and library organization; and more!

    Don't put a political spin on this.

    Craze cracking is singular term implying a thermal reaction.

    By an insurance company:
    Craze Cracks (Thermal) ? Craze Cracks are a result of the mat of the asphalt shingle drying out over time, which causes the mat to shrink and results in surface cracking. Shingles that exhibit this within a few years of being installed may indicate a manufacturer defect with the shingle. Prevention: Craze cracks occur due to normal age and wear, so they are difficult to prevent. Treatment: Craze cracks are very common on roofing shingles and are usually harmless. When shingles exhibit craze cracks, they don?t necessarily need to be treated or replaced.

    Nothing "political" Robert, at least from me. The article was a waste of my time.

    1. Writing does not make someone an authority or even correct.
    2. Contradictory statements in the document that you posted earlier makes it worthless.

    Follow an age time line. It makes perfect sense when you think perfectly Jerry. That would be without bias to the association many love to hate.

    Robert,

    In my opinion, the better way to state the above is like that: 'the association that does what it can to make many hate it'

    No need to rehash the years of arguments.

    "It makes perfect sense when you think perfectly Jerry."

    That makes no sense when thinking reasonably, let alone when thinking perfectly. It apparently looks good enough to some, though.

    What does "graze cracking" have to do with a question about granual loss on asphault shingles? Absolutly nothing.

    Seriously Robert, would you NOT call out the condition of those shingles in the pic included in that article?
    Not call them out because you were afraid of making a client unhappy, because you were performing a computent inspection with their best interest at heart?
    This has nothing to do with association politics. Its about drinking the cool-aid blindly without thinking for yourself. It's about believing someone, not because of their expierience in the field or lab, but because they wrote something for an association you believe in.

    I don't give a dang who it was who wrote that, or where it originated from, if that surface cracking is considered a "normal" condition and should not be mentioned...but yet it mosly happens at the end of the life of the roof. Why write anything about it at all?

    Please let me know Robert.

    Elizabeth, I see you have little reference to performing a home inspection.
    As explained by Carson Dunlop. A home inspection is a professional consulting service that determines the present condition of the home's major systems, based on a visual inspection of accessible features. ... Inspections are often performed during a real estate transaction but may be done anytime.
    As too present condition, I inform my clients on condition. The state of something 'with regards to' its imitate appearance, quality and/or present working order. IE: Good or adverse.

    My opinion of your posts. Some one that has very little credible knowledge of the industry.

    My I recommend. Post reference metal to back up a claim.

    Please Jerry, or any one on this thread. Please, provide InspectionNews a personal/professional article written by yourself. ... aimed at the home inspection industry in general. Not a scholarly article please. Just a reference article for other home inspectors or the public.
    Thank you for you cooperation.

    The OP posted a manufacturing defect. "Granules missing on just a few shingles???" I posted another.

    Robert,

    You said to Elizabeth "My opinion of your posts. Some one that has very little credible knowledge of the industry."

    My opinion of your posts is of someone who 'has not spent time learning about inspecting for the benefit of one's client', instead, one has been concentrating on avoiding tough calls, falling back to SOMEONE ELSE'S training guide FOR NEW inspectors.

    And "My opinion of your posts. Some one that has very little credible knowledge of the industry." applies to you - quite well stated, actually, thank you.

    One must learn to grow a set (figuratively speaking) and stand up for their client's interests, NOT acquiesce to real estate agent pressure to not make correct, but tough, calls.

    Calling someone out, who is new and learning to do things the right way for their clients, while apparently acquiescing to marketing pressure is quite unbecoming to one who promotes themselves as being a 'knowledgeable professional', and especially if one promotes themselves as being a master of the profession (which I recall you said you were - please correct me if I am not remembering that correctly).

    Robert,

    You have something against professional articles?

    And you would rather read articles written that require no thinking on your part?
