In February we had this snow storm and while the ice was melting another snow storm happened than I realized the leak coming on my roof was due to ice damning, which prompt me to call several estimates to have my roof redone as it has been over twelve years and the original roofer did not install an additional layer under the shingles to protect my roof from the ice damning situation. City 1 Roof gave me the best price and quality of work for what I was seeking for, which is the extra underlayment to protect me from the ice damning. Danny came over to provide me the estimate and explained about the materials he would be using so, I was sold on Diamondeck system. The men did an excellent job on the flat roof, the shingles and skylight all done in two days and after the job done they clean all the debris on the deck and disposed all the old shingles on their truck and carried away. I recommend their job without a blink.
