Common Roof Issues

Ponding: Water accumulation on your roof can lead to leaks and structural damage. Our team assesses the cause of ponding and implements effective solutions to ensure proper drainage and prevent future issues.

Dry Rot: This type of fungal decay weakens wood structures, compromising the integrity of your roof. We identify and remove affected areas, replacing them with high-quality materials to restore your roof's strength.

Weak Areas: Over time, certain areas of your roof may become weak due to weather exposure, poor installation, or age. Our experts reinforce these areas, providing additional support and protection against further deterioration.

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!
