"Cortez Roofing did a great job replacing the roof on my house. I would highly recommend anyone looking to replace their roof to call and get an estimate from Edwin at Cortez Roofing. The price was considerably less than the other two estimates I received and the quality of the work was excellent. Great job guys. Thank you!"

"They did a fantastic job replacing my roof. It was done in a timely manner and there was great communication during the entire process. All my questions were answered, and my worries/concerns were addressed before they started the job. Guardian roofing was very honest, gave me a great price, and was really easy to contact when I had questions. I was able to place my outdoor furniture in the garage and that made it much easier for them to clean up after. I had no nails around the parameter of the house and no left over debris. They did a fantastic job on my roof, and the clean up, Iâ m so pleased with how it turned out. My house looks beautiful, and they were enjoyable to work with. Very kind profess workers as well."

"I had some moisture in my siding. Instead of repairing the siding, they inspected the roof and identified the core issue. Brenna was my project manager,explained their process to me. Was present when the insurance adjuster inspected my issue and completed the project with no surprises. I am very satisfied Alpha Y Omega and their commitment to doing what they say and doing it."

"We had a large area of 15 yr old wallpaper that was removed, drywalled, sanded, and painted. From the beginning inspection/estimate by Dan Espinoza to the crew leader, Sean, there was clear communication. My home was treated with respect taping down protective paper/drop cloths to protect the floors. No corners were cut to do the job right. I highly recommend this great company to do fantastic work on your home!"

"I accidently called Murray Roofing while looking for another roofing company that was referred to us by a realtor. Best accident ever. Dave was knowledgeable about the product and was patient with us as we made the decision. The roofing crew was very polite and went right to work when they came to our home. We were happy with the clean up after the job was finished. I would highly recommend Murray Roofing"

Roofing FAQs, answered by experts

Properly installed chimney flashing can last anywhere from 15 to 50 years. However, flashing generally only needs to be replaced when it is damaged, corroded, or no longer creates a watertight seal. Several factors influence its longevity, including the material type, quality of installation, and local climate. For example, copper flashing tends to last longer than galvanized steel. Large storms and extreme weather can also damage flashing, potentially requiring earlier replacement. To ensure its longevity, it is recommended to have your chimney and roof inspected annually. A professional can assess the flashing's condition and recommend any necessary repairs.

Generally, the term “rolled roofing” refers to MSR (mineral surface roll) roofing. This type of roofing is similar to asphalt shingles but comes in a roll that’s unraveled and installed over your roof deck. There are many types of rolled roofing, including TPO, EPDM, and modified bitumen roofing (aka torch down roofing).

The golden ratio for roof pitch is 1:1.62. It’s simply a standard aspect ratio that home and building designers and architects use when deciding how steep a roof should be to maintain visual appeal. The golden ratio can apply to any home or structure with a visible roof that isn't considered a flat roof.

The material and frequency of maintenance are the biggest factors for determining the longevity of your shingles, not the color. For instance, luxury asphalt shingles can last 30 years or even longer, while slate tiles have an impressive lifespan ranging from 75 to 100 years. That said, lighter-colored shingles can help reduce your energy costs in the summertime.

Roof sheathing can buckle from moisture damage, too much weight from roofing materials, or too much space in between rafters without thicker sheathing to compensate for the added distance. Bucking roof sheathing is a serious problem that can lead to a collapsed roof, so have a qualified roofer near you come to identify the problem as soon as possible.
