"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."

"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

Roof vents are an essential part of a roof, as they promote energy efficiency by keeping warm, humid air at bay. The roofing material, especially asphalt shingles, will not last as long as it should (about half of its manufacture life) if the attic is not ventilated. Also, going without ventilation means having a warm attic that demands more from your air conditioning system (and your wallet, once the bills come). Ridge vents and roof vents also prevent a host of other icky moisture-related problems like rot, mold, and mildew.

Architectural shingles and impact-resistant shingles aren’t mutually exclusive, which means some architectural shingles are impact-resistant shingles. Architectural shingles are thicker and more durable than standard 3-tab shingles, and they become even stronger when they also have high impact resistance and wind resistance ratings. The most durable shingles for areas with extreme weather are architectural or luxury shingles that have a Class-4 impact resistance and a Class-H wind resistance that can stand up to winds reaching 150 mph.

Your chimney needs a structurally sound chimney cap, protective lining, damper, chimney flashing, and brick and mortar to prevent water from goind down your chimney. A pro can help you identify where the issue is so that you can stop water from coming down the smoke shaft, through your damper, and into your home.

Installing a green roof costs between $10 and $30 per square foot. Green roofs cost slightly more than standard roofs, due to the extra materials and installation know-how required. The type of green roof you choose also impacts the cost, with intensive roofing systems costing considerably more than extensive roofs.

The warranty for algae-resistant shingles varies by manufacturer, but the industry standard is 25 years for overall shingle durability and lifespan and between 10 and 15 years for algae resistance. Some products come with longer warranties for discoloration of up to 30 years. Check warranty coverage for the shingle and algae protection before deciding on a roofing product.
