"Please read carefully. Because this is not only a glowing 5star plus review for CNY Complete Contractors (CNYCC) but what to expect from the competition. I looked first at two advertised roofing companies. The first you see all over. M Quick to quote but definitely inexperienced as the quote included roofing a plastic Rubbermaid shed. (Seriously) Thank you Adam owner of CNYCC for pointing that out. The second on was also higher priced and charged too much for plywood (like double for the same size. Adam was recommended by my best friend who had CNY put on a brown roof which looks great on his house. CNYCC came over explaining the job and looking closely at details such as my outdoor porch. They stood in communication with me. (Text are sent only after they have your permission. So the one bad reviewer needs a lesson on spam texting and the proper use of email and communication ) Give them time to get to you in the spring and summer. We had them come out in the winter. It’s definitely worth the wait. They also saved up money over those other two companies. This is family friendly and run business. Paige, Adams wife was wonderful. She kept me informed help me through the financing process, and her communication was outstanding. She told me exactly when they would be coming out to do my roof and they showed up that morning to the exact time she said. Adam gave me an explanation of what they did and how they would proceed that day, which was another reassurance of our previous conversation, so I was completely comfortable. He said one day to take off my old roof and replace any plywood. I didn’t believe it. But came 5pm and my wife coming home from work that night and we had a completely new roof with new plywood in places we didn’t see at first were bad until Adam showed us on our home. Thank you so much! His crew was so professional. Any nails were picked up with a magnetic roller. I didn’t see any in the lawn for my tractor to puncture a tire, which was incredible. Thank you again!! I only saw a few come out of the gutter (that is too be expected). I had my house washed a week after and really have to say the Biscayne Blue on our house has had neighbors complimenting as they noticed an immediate difference. We are so pleased and have complete peace of mind knowing that the investment we made has a warranty we can pass down to our children and labor covered for longer than any other company and is covered even if CNYCC is not available. Ask Adam to explain. He also helped to make our porch, which is our pride and joy, look so much better doing some finishing work after the new plywood was put on per our conversation which in our opinion was going way above and beyond. He definitely knows his craft. John his foreman helped too to make it happen. If he only did landscaping, and about another dozen projects. Thank you again CNYCC!"

"Erie Home Basement Solutions was a pleasure to work with. Everyone was on time, and always polite and courteous throughout this process. This is extremely hard work and they continued to always have a smile on their face and answer any questions I had. They worked diligently to complete the project on time and fulfilled all aspects of the contract. Actually, they went above and beyond to make sure I was pleased with their service, which is unusual in todayâ s work culture. I would highly recommend this company for your basement waterproofing needs."

Roofing FAQs, answered by experts

A chimney cap costs about $300 on average to install, with prices ranging from $75 to $1,000. The final cost depends on several factors, including the professional you hire, the accessibility of your chimney, the cap's material and size, whether any repairs are needed, and if it requires custom fabrication. Chimney caps are usually made from galvanized steel, stainless steel, or copper. Copper caps are the most expensive, followed by stainless steel and then galvanized steel. Excluding labor, average material costs are around $100 for galvanized steel, $250 for stainless steel, and $600 for copper. You may also face additional costs, such as hiring a chimney sweep to clean the chimney before the cap is installed.

The number of snow guards you’ll need on your roof depends on factors like the type of roof you have, its slope, the orientation of your home, and the snow load in your area. A local roofing professional or the snow guard manufacturer can help you determine the ideal amount.

The common formula for measuring a roof is length x width equals square footage. Professional roofers measure the length and width of your roof, including dormers, and determine its pitch and rafter sizes. If a roof surface is a triangle, they’ll divide that square footage by two, then add up the square footage of each surface to get the total for the roof.

Depending on the type of damage your roof shingles have, you may be able to simply repair them without having to replace them. However, if there are more than a few to repair, replacement is likely the easier option. You may only need to replace a few of them. Repair shingles by applying roofing sealant directly under the shingle's damage and then directly over it. 

Yes, copper roof strips can help prevent shingle damage and are an alternative to algae-resistant shingles. They work in a similar way: they release copper ions that interfere with algae, moss, and other plant growth. Algae feeds on limestone in your roof shingles, and moss can uplift shingles and increase the risk of leaks. If you have issues with algae or moss on your roof, copper roof strips can help avoid damage.
