"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."

"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

If a home isn’t properly winterized, the pipes can freeze and burst, causing flooding and massive property damage. It can also leave your house susceptible to pests, which can infest it and cause significant damage. Winterizing a home can prevent many potential issues and save you money on costly repairs.

Tile roofing is durable, fire-resistant, and energy-efficient. It also adds aesthetic appeal and, with proper maintenance, can last 50-100 years.

This will depend on your existing roof to some degree, but it’s common to raise a roof 4 to 8 feet. The exact amount you can raise is subject to the existing structure. For most homes with average roof slopes—20 to 45 degrees—you can raise the roof around 5 feet.

A standard roof can hold a live load of about 20 pounds per square foot. However, gable roofs often have steeper-than-average slopes, so calculating their weight capacity can be challenging. If the slope of your gable roof is greater than 4:12, the live load needs to be decreased to allow for a larger dead load. Ask your roofer exactly how much weight your roof can support.

Common problems include loose or missing shingles, leaks, and weather damage. Regular inspections help prevent major repairs.
