Roofing/IKO Shingles


Laura Butler wrote at 2007-06-15 18:20:09
I just heard that there was a class action suit against IKO so I googled and found this site.  We put IKO shingles on our indoor riding arena in the spring of 1990.  We got the info from IKO to make a claim but found out that we didn't have the receipt anymore or couldn't pursue it.  

Our arena is 60' x 136' and has 10 of the vents that twirl at the top and with venting on the side, under the roof line. The shingles were almost all gone.  All the roofers had to do was roll the tar paper up and the remaining shingles came off.

I have a 14 year old house with 30 year shingles made by IKO - they are totally gone!  I have ben told by numerous contractors it is 'shingle failure' but nothing will be done because IKO will claim something was wrong with the ventilation, or we don't have the necessary documentation.  We are the original owners of the house but we do not have a receipt from the builder for the shingles - only a cancelled check, which IKO won't accept.  

IKO shingles are inferior and I suspect there are a lot of us out there who are having the same experience! I have an estimate to replace the roof of $25,000!

All the product manufacturers including IKO have specific ventilation requirements, and your roofing contractor should be aware of those as well as the FHA guidelines, international building codes, and so forth. These are not mysterious or overly complex formulas, they are pretty basic. You need 1 square foot of attic ventilation for every 300 square feet of attic floor space minimum, and a 1/150 ration where less than a 60/40 balance of intake to exhaust ventilation. These are all terms and calculations that a reputable roofing contractor will be familiar with. "There was no ridge vents or any other ventilation on the roof." This is an oversight on the part of your contractor, and the shingle manufacture is not at fault.

I have failed IKO shingles on my house and it ventilated with a continuous drip edge vent all around.  In addition to this there is a full ridge vent.  The issue is with the organic shingles that IKO produced and that is why they are being sued and why they have a claim form on their website.  For SuperRoofer to write that it is not the fault of the manufacture that it is the installer is Total BS!

All aspects of residential Roofing. This includes shingles and flat (low slope) roofs. I have knowledge in the installation as well as the design of roofs from an engineering standpoint.


I have been doing roofing for 40 years. This was my father's business and I took it over in 1980.

I have written responses to artcles that I felt needed a response to and those responses have been published in roofing trade magazines.
