"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

In some cases, yes, you can put a second roof layer over architectural shingles, but it depends on your home’s structural stability and the local building codes where you live. Architectural shingles are thicker and heavier than standard asphalt shingles, so you may need structural reinforcement or a structural engineer’s inspection before proceeding. Additionally, some building departments don’t allow for two roof layers, regardless of the roof type. You should ask a professional if ripping the old roof off before installing the new one is the best option for you.

Verify that your roof is licensed and insured by visiting your state's contractor's licensing association. Most states have a database to double-check your contractor's name and address against the information provided. The contractor should also display both their license and insurance on their website with links to the related agencies.

A well-maintained tile roof can last anywhere from 40 to over 100 years, with its exact lifespan depending on the material and level of care. Proper maintenance, which includes keeping the roof clean, free of debris, and performing routine repairs for any cracked tiles, is crucial for longevity. The lifespan varies significantly by tile type:

  • Clay, terracotta, and slate tiles are highly durable and can last over 100 years.

  • Concrete tiles typically last from 30 to 100 years.

  • Metal tile roofs generally last between 40 and 70 years.

  • Composite tile roofs have a lifespan of 20 to 50 years.

Be aware that maintenance for a tile roof can sometimes be more expensive than for an asphalt roof.

Yes, shingles should overhang the drip edge, typically between 1/2-inch and 3/4-inch. An overhang shorter than 1/2-inch can allow wind-driven rain to get under the shingles and damage the roof deck or fascia. Conversely, an overhang longer than 3/4-inch increases the risk of shingles getting caught by strong winds, which can lead to roof uplift. Always check your local building code for exact overhang requirements in your area.

Gaps between tiles are necessary to help with weatherproofing, allow for thermal expansion, and increase wind resistance. In general, a small gap no larger than 3 millimeters wide will encourage proper drainage and limit cracking. Beyond that, tiles should overlap a minimum of 3 inches, except at the eaves where they should extend to the center of the gutter.
