Great company and the quality of work was superb. They were very transparent about the cost upfront and open about all our needs throughout the project. They also completed the project in one day and we are delightfully pleased with the end result. Great price, great quality, great company...

Our experience with GRP Construction Services LLC was nothing short of amazing. We used them for our roof installation. They were well trained and true roof experts and did such an excellent job on our house. In addition to being professional and knowledgeable, Geovanny is an awesome guy who makes you feel at ease, and it was a pleasure working with him and his crew. They were very professional, have excellent products, completed the job on time and cleaned up very well behind themselves. The work was beautifully done, and they even took care of a couple small things that popped up that were not originally accounted for at no extra charge. Overall, the experience was fast and stress-free; the pricing was extremely reasonable; and the finished work was beautiful. I will rate them 6 STARS (OUT OF 5)...

We hired GRP Construction Services to replace our roof and had a great experience with them. Giovanni was extremely prompt with responding to our inquiry and coming by to look at the roof, and was friendly and happy to explain their process and different roofing materials. We got quotes from three different contractors, and GRP was priced competitively. Communication was timely and clear throughout the whole process. Our roof was done in one day and looks great. We noticed a new structural issue in our attic the day after installation, and they were quick to come back and help us with that as well. Highly recommended...

I recently discovered some water damage to our flat roof portico and contacted multiple roofers to determine the extent of the damage and the cost of repair. Some returned my calls, but many did not. Of those who did, all stated they didn’t work on flat roofs. Thankfully, one of the roofers recommended GRP Construction Services, a company that works on all roof types, including flat roofs. I contacted GRP for an inspection and estimate and received a quick response, followed by an appointment date within the week. The inspection was done by Giovanni Palacios, the owner, who showed me how the original builder had not sealed the portico roof properly and the damage that had caused. He explained what needed to be done and provided an estimate. We were able to schedule the repair fairly quickly. The job took one day with little disruption to us. Giovanni took photos of the work performed during each phase of the job and emailed them to me when the job was completed. I appreciated this transparency and was satisfied with the work that was done. I found Giovanni to be honest, conscientious, responsive (even after the job was completed) and reasonably priced—a combination of qualities that is often hard to find...
