I did give 5 stars at first but then i had another technician come look at my A/C unit. Eric was very nice and helpful but was charging me more than I actually needed. I called someone else to come get a second opinion because I thought I was being charged way too much. Turns out, I was. The other technician said it was my capacitor that needed to be changed only. That it had looked like someone tampered with my unit to make it seem like I needed a lot more done. Grandmark said it was my circuit board and capacitor. That was a lie. I will not recommend this company and i will get more opinions from now on.

I would like to commend Angel C. and his team for doing such a great job in repairing my roof , removal and reinstallation of my solar panels as well as cleaning my gutters. Angel was very responsive to all our concerns and makes sure that the job gets done according to our satisfaction. Customer service was excellent from the start when I spoke to Jose who was very pleasant and was empathizing with our roofing issue. Angel C. sends us photos and videos of before and after the work is completed which was very reassuring to homeowners like us. I would definitely recommend this company for roofing services and issues that homeowners have.Again thank you to Angel C. and his team!

Why Choose Asphalt Shingle Roofing?

Asphalt shingles are the most popular roofing material in the United States, and for good reason. They are durable, cost-effective, and come in a variety of styles and colors to match any home aesthetic. Here are some key benefits of asphalt shingles:

  • Affordability: Asphalt shingles are one of the most economical roofing options available.
  • Durability: When properly installed and maintained, asphalt shingles can last up to 30 years.
  • Versatility: Available in numerous colors and styles, they can complement any architectural design.
  • Ease of Installation: Asphalt shingles are relatively easy to install, reducing labor costs and installation time.
  • Weather Resistance: They provide excellent protection against various weather conditions, including wind, rain, and hail.

Common Asphalt Shingle Roof Problems

Despite their durability, asphalt shingles can experience issues over time. Some common problems include:

  • Curling and Buckling: This can occur due to improper installation or excessive moisture.
  • Missing Shingles: High winds and severe storms can cause shingles to detach from the roof.
  • Granule Loss: Over time, asphalt shingles can lose their granules, which are essential for protecting against UV rays.
  • Leaks: Cracked or damaged shingles can lead to roof leaks, causing water damage to your home.
