Testimonials

Honest Reviews From Our Clients Who Have Used Our Services

Our first roofing experience with our 17 year old home. Found out our slopes/valleys were compromised along with 25 other roofing tiles that were cracked or completely broken. Grandmark Service Company came and did a thorough inspection, along with taking pictures of the problem areas and then sat down with us to address them all.

Tony and Brian were very polite professional and proficient. I was very impressed with the work and would highly recommend the company.

All the workers with Grandmark were very professional. They worked fast but got the job done correctly. Geraldo was especially helpful with information and timely work completion.
