***AWFUL FROM START TO FINISH. This may be a long read, but please learn from my mistakes whether you choose Omega or another vendor. Please note I gave Omega over a month to address my concerns before posting any negative reviews. I sent Omega detailed pictures of every concern to ensure my claims could not be disputed otherwise. Unfortunately, only a few concerns were addressed, and Omega failed to bring out an inspector on two (2) occasions to address my other concerns. Basically no major resolution occurred and therefore I decided to post a negative review. The entire process from the sales to installation was unacceptable. If I had not kept an eye on the installation, I would have been the average unsuspecting consumer not knowing how poorly the install was. My detailed complaints are below in chronological order: Incorrect Shingle Selection - The salesman told me shingle selections came from a catalog solely based on COLOR only. That is incorrect! I reached out to the shingles vendor [i.e. Owens Corning] myself, where they confirmed my suspicion. In actuality, the salesman was very misleading as he should have stated all shingles have different quality, prices, patterns, construction, etc.. NOT JUST COLOR! After the install and physically seeing samples, I quickly realized I would’ve installed something else. Bummer! $50 Shingle Samples - The salesman denied me a sample of the shingle I selected. Finally, he agreed to provide a sample at a whooping cost of $50!! Therefore, I did not want to pay that additional charge and “trusted” the salesman to proceed with the sale. A great error on my end! When I spoke with Owens Corning, they told me samples are free. Also, speaking with Omega after the install, Omega said they have plenty of samples around their office and could not explain why the salesman wanted $50. Shingle Delivery During Heavy Rain - I told the salesman not to deliver the shingles as heavy rain was coming. The salesman was very rude and snappy. He proceeded to have the materials delivered, and the materials were not protected from weather elements (i.e. covered with a rain tarp). It rained and the workers installed wet products. Anyone knows wet materials should not be used for installation. Who knows what that will inevitably do to shorten the longevity of my roof! Moss Growing on Shingles - I told Omega the shingles were wet. I sent pictures of moss growing on the shingles. Not only should wet shingles not be used for installation, but GROWING MOSS on the shingles?! When the wet shingles were placed on my roof, you could see water flowing down into my gutters. I asked the workers and they said it was perfectly fine and continued. Ran out of Material During Install - One of the materials (i.e. underlayment) clearly ran out. Underlayment is a water resistant and waterproof barrier installed directly on the roof deck for weather protection. When I saw this problem, I confronted the installers and they just simply stated “we ran out of material”. Then they proceeded and continued on. Unacceptable! Furthermore, underlayment has to be installed and smoothened out without wrinkles. For my roof, there were areas where the underlayment was wrinkled during the install, but they never went to smoothen it out either. Quickly Disposed Any Remaining Shingles - Based on my roof size, there were approximately 3 extra bags of shingles purchased. After the install, I asked to keep a few shingles from those extra bags and the workers told me they were immediately thrown away! I paid for those extra bags as part of my contract, and there were no shingles left for me to keep as a sample after the fact? That is unbelievable and seems VERY VERY SUSPICIOUS. Whether you proceed with Omega or another contractor, please learn from my mistakes and even feel empowered to stop your contractors if things are going very wrong! Good luck!
