My concern is why this damage on only certain spots of the roof and not the whole roof.


Attic has blown in 10" of insulation. The defective side has air traps installed to let air flow from the soffit vents to the attic. The side that is ok, doesn’t have these air vents, just the soffet vents, that look to be covered with insulation inhibiting the air flow.


Any ideas on why the damage only in spots. ?

Give the wear pattern, my guess would be several defective bundles of shingles, probably as a result of storage conditions. But exactly what that defect would be, I don’t know.

I would recommend the a qualified,licensed, and insured roofing contractor further evaluate the apparent defect. Just document and advise on a course of action.

There is no need for "evaluation" here. The material is no longer functional. Replace it.

I wonder how long they sat at an outside storage facility in the sun and rain, maybe snow, before sold and shipped to the site. looks too spetratic to be any kind of vent issue. icon_cool.gif

Thanks for the feedback - You all confirmed what I thought - Being 10 years old - do you think they have a chance on going back to the manufacturer?

usualy 3 tabs were sold as 15 or 20 yr. shingles. with all the right paperwork and mayby a good lawer, they might stand a chance. icon_cool.gif

And if they get replaced after all the right paperwork and a good lawyer, the owner will still have to pay for installation.


Their best bet (and probably cheapest) is just get it fixed. It will need replaced long before any lawsuit will be over anyway.

I think most shingle manufacturers know this.

This looks like a “Long ago roof repair”.


The shingles that look better have been replaced.

Yes, the whole roof should be considered for replacement.

How old the roofing is, is irrelevant at this point.

The roof condition has exceeded it's life cycle and needs to be replaced.Further evaluation by a Roofing Contractor is recommended.

I agree.

What are we evaluating?

Everything else that is part of the re-roofing process, related items such as flashing, boot condition at vents stacks, chimney flashing, stripping, ice& watershield extent, underlayment felt,and more.
There is more to just saying a roofing is at it's end, a lot of other components fall into play and final evaluation of the extent of repair is born by the Professional not us. It is one thing to point out the roofing needs to be replaced, but another, to say to what extent.
If anything else, the Roofing Contractor will most likely agree with the condition of the roofing, from that point on, you are out of the picture and on to something new.
