    Default Unfamiliar Wear and Tear?

    Has anyone seen this type of deterioration before?

    Is it "normal" or maybe a product defect?

    Randy,

    Fiberglass mat roll roofing intended to be used (originally) as BUR with flood coat of hot asphalt over it to protect it from the sun.

    Later used as exposed roll roofing (no flood coat).

    Without that flood coat of hot asphalt, you will just what you see there - seen it many times.

    Time to replace that roof.

    How wide between laps. Typically that stuff was put down at 3-ply, sometimes 5-ply, and, yes, sometimes at single-ply (which makes it doubly bad).

    I think they forgot to finish the roof.

    And they installed it "Chicago Style" with vertical rows instead of lap style.

    Why the BUR for a sloped roof?

    Dom,

    I think it is a flat roof (low-slope roof), it's just an optical illusion of the slope.

    See that narrow strip? That is the 'ridge'.

    At least that what what I thought.

    Jerry,

    You may be right about the optical illusion. It looks like a 4 or 5/12 pitch in that 3rd photo.

    Thanks Jerry and Dom.

    Its crazy, but the roof is actually sloped more than enough for shingles.

    Don't know why they chose this product. . . especially the vertical row installation!

    It's a publicly funded home. Maybe a commentary on the wisdom of our government.

    You were right.

    Dang, to install that vertically like that, that means (there are cases in which you can install stuff vertically, just the laps change, not sure that stuff is allowed to be installed vertically, though) the the bottom lap of 2" is non-existent (sheets run top to bottom) and that the side lap of 6" applies to those sides all the friggin' way up from the bottom to the top, every single vertical row.

    What a waste.

    Plus, those 6" side laps are based on not more than 36" material before overlapping another sheet where the water can get out. Installed vertically like that, even fully lapped, there is no way to get the equivalent lap.

    "Don't know why they chose this product. . . "

    Cheap and fast. That roof job is one step up from a blue tarp.

    "It's a publicly funded home. Maybe a commentary on the wisdom of our government."

    I bet if you did some digging you'd find that roof covering and installation method was not in the specs for that home.
