"Guerrero Roofing called me immediately in response to my inquiry. He came the same day of my inquiry and re-roofed the half of my roof area in order to stop a leak. Mr Guerrero and his son's were very professional and I am very satisfied with their work. His price was reasonable. I have additional work that I have asked him to give me an estimate. I recommend Guerrero Roofing."

"It was Saturday night when I heard a strange noise outside. I went to see what it might be when I noticed several shingles tore off the roof. I immediately came inside and started searching the web for suppliers who would be open on Sunday. That’s when I came across Buffalo's Best Roofing. Buffalo’s Best Roofing was open on Sunday and able to supply me with the shingles I needed to repair the roof. I will definitely use Buffalo Best Roofing for any projects I have going forward. The concern they showed about my issue and, the professionalism of the people I spoke with sold me."

"The big winds on a Sunday in early March blew a number of shingles off our roof. Five days later on Friday, Stellar had replaced our roof. We got several estimates. Stellar wasnâ t the lowest but it wasnâ t that much higher. We felt most comfortable with their estimate and the products they were going to put on our roof. A tear off and roof replacement done in one day. Professional and efficient."

"Long gave us an accurate roofing inspection and estimate. Brian Wahl was informative and professional from the initial assessment, the explanation of the construction process and materials used,to the signing of the contract. The front office was the same way in getting our project underway. Looking to having them install our new roof."

"Jose and his crews did a great job in brutal temperatures. I would recommend them to anyone who needs a new roof. Our roof is a little difficult as we have channels between roof sections and that was done well using the singles to create the channels for the water to follow between roof sections. Also loves the Owens Corning amber color, no more black roofs as far as the eye can see."

"Because of the hail storm our roof needed new shingles. We had the good fortune to be introduce to Matt and Tall Pines Roofing. With the help of Matt, the process with the insurance company and the insulation of new shingles was made (for our part)stress free. In one day our old shingles removed and new high quality shingles were installed by a professional and dedicated crew who worked tirelessly until the job was completed. Leaving the premises and grounds as clean as when they arrived. I am very happy with the new look of our roof and would highly recommend contracting Tall Pines Roofing your shingles for a new roof or replacing old existing shingles."

Roofing FAQs, answered by experts

You should definitely be wary of roofing contractors who offer significantly lower prices than their competitors. Most roofers in the area are all dealing with the same cost of materials, and labor costs are often comparable, too. If they’re significantly cheaper than other companies around, it could be a scam. Read reviews and ask other roofing companies and contractors if they’ve heard of the suspected scamming company.

Copper roofs last an average of around 100 years, making it one of the longest-lasting types of roofs. It’s significantly more expensive than an asphalt shingle roof, but it also lasts three to four times as long, providing great value for the money. You can extend the life of your copper roof by carrying out routine maintenance, like scheduling annual cleaning and roof inspections.

A gable roof costs between $13,000 and $30,000, depending on the size of your roof, the materials you use, and the type of gable roof you install. If you’re building a gable roof for new construction or as part of a major home remodel, your pricing will also depend on the type of roof trusses you use, how accessible your property is, and some other factors.

A chimney liner is typically easier to install by pushing it down through the chimney with the help of a rope. Depending on your fireplace and the type of liner, installing it by pushing it up through the chimney could work, but operating from the top down is usually the best option.

Whether you should choose a flat roof or a sloped roof depends on your particular situation. Flat roofs tend to be less expensive to install. However, sloped roofs have longer lifespans and stand up better to heavy snow and other inclement weather.

Keep in mind that even a flat roof needs to have a slight slope, usually around 1/2 inch for every foot. If it is completely flat, water will pool and cause damage, either from weight or leakage or rot.
