"From start to finish, Positive Results Roofing was excellent. Quick response on the estimate as well as to any questions I had. Very hard-working and highly skilled with a price that fit my budget. My new roof and gutters look great! If you need a new roof, this is the place to call."

Customers say: Terrific value

"It was a pleasure to work with IM Roofing. Mike was responsive, and professional. Licensed and insured. I ended up with a great roof. More details: I contacted several roofers, and joined them on the roof of my house looking at various details that needed addressing. I have a mixed roof, with some shingled areas and other flat areas. It presents a number of concerns, not just limited to the complexities of how to keep things watertight, but also including details such as where water is legally allowed to drain. Mike was the star of the lot that I spoke to. While all the experts I contacted had some insight as to why my roof had issues, Mike was far more insightful and comprehensive about what needed to be done to effect a permanent solution. In some areas, the crew ended up stripping and (due to site requirements) hand carrying away a total of three old wonky layers of roofing, and then installing a new, modern roof. I was impressed with their efficiency and care. I can head into our next rainy season with confidence."

"They are experienced roofers that are proud of their work. Prices are competitive and I am glad I did not have to waste time collecting several quotes. They come to inspect your roof, explain in details roofing terms in a clear way I understand, then they give you the estimate and from there it is a straight forward process. Next thing I know my roof was repaired in a couple of days. The workers are hard working people and the supervisor is there to overlook everything and make sure to resolve any unpredictable situation. There was a bird nest near my chimney and they placed the nest with a couple of eggs on a nearby tree. That was so thoughtful! A few years forward, there is no issue on my roof. My house is 40 years old and I need a new roof to be able to install solar. But the repair done by KiTA guys was so well done that I am postponing. I will hire them again and recommend KITA Roofing for family and friends."

Roofing questions, answered by experts

The principal, common, and auxiliary rafters are the most frequently used types of rafters. Principal rafters are large and typically appear toward the edges of the roof. Common rafters are smaller than principal rafters. Some people may use a mix of common and principal rafters. The auxiliary rafter is not common, but it provides extra reinforcement for a principal rafter on a large building.

Torch down roofing is only one of the options available for your home. Depending on your type of roof, if it is a gable or hip roof, torch down roofing might not work for you due to the slope. Asphalt, metal, and clay shingles are just a few popular roofing options that may be more suitable.

Roof underlayment usually lasts as long as the roofing material that covers it, as it’s not directly exposed to the elements. In most cases, roofing companies will replace the underlayment each time they install a new roof. In some cases, particularly with slate, clay, or certain metal roofs that can last 50 to 100 years, your underlayment may require replacement within that timeframe, especially if you start to notice roof leaks.

Yes, moss can be dangerous for your roof if left in place to grow without treatment. The moss soaks up and holds moisture. Having a constantly damp roof could lead to problems with rot for the parts of the roof that consist of wood. Additionally, a patch of thick moss may draw insects and birds, which could damage the roof. Thick moss could block the roof’s drainage system. Water then may back up after a rainstorm and cause further damage that could eventually lead to roof repair expenses or the cost of roof replacement.

While the terms are often used interchangeably, wood shakes and wood shingles have notable differences, primarily in their manufacturing and appearance. Wood shingles are machine-cut on both sides, resulting in a smooth, thin, and uniform product. In contrast, wood shakes are typically hand-split or sawed on only one side, giving them a more textured, natural, and rustic appearance. Due to these manufacturing differences, shakes are generally thicker, heavier, and less uniform than shingles. They are also more expensive. Homeowners seeking a more rustic aesthetic often choose shakes, while those preferring a more uniform look may opt for shingles. Both are installed in an overlapping pattern to create a durable, weather-resistant roof.
