Melanie from Minnesota:
Would anyone happen to know what type/brand of shingles I have on my roof? My new roof was installed Dec 2021. I contracted to have IKO Dual Black installed (documented on the contract) and with in the first year my roof starting to bow and buckle with shingles swelling and curling upwards, they had a look of wet cardboard. One of the shingles (shown in the picture) lost some of the asphalt leaving behind an exposed thick woven type of Jute fabric, the asphalt seems to sit on top of it not embedded into it like all of the shingles I have researched (I know very little about roofs and shingles but something didn't seem right). I reached out to IKO and they said it's similar in looks to Cambridge but the tooth sections are too big and that they had never seen anything like it (the fabric). This came from two different members from IKO trying to help me identify my shingles. One spoke to several colleagues and they couldn't identify it either. A family member who also recently had their roof redone with IKO Cambridge had a few sheets of shingles left over along with some smaller cut off pieces, so they tried to replicate ours by picking off some of the top part and they couldn't. They were able to break off a small section and the fiberglass was fully embedded into the shingle and not a solid woven fabric. The fabric itself doesn't look or feel like fiberglass, it's looks/feels more organic like Jute or Burlap. I have the contractor saying they are Cambridge and I have the shingle manufacture telling me they aren't. Please help! My roof is falling apart only 15 months after install. I do have a lot more photos I can share. Thank you
Here is what John Kenney from Cotney Consulting Group said:
This one is bizarre. I am not sure who manufactured this shingle. I agree with IKO that it is not one of their products. If it was Cambridge, it would have fiberglass reinforcing matt.
My opinion: this is some sort of organic mat that I have not seen. Most organic mats are saturated with asphalt during manufacturing which this one has no asphalt saturation. I am not even positive if this shingle was manufactured in the US or Canada. No major manufacturer I have researched has a shingle and organic mat like this.
