"We had a very rough time finding someone who could fix our roof with out simply replacing the whole thing. They were able to repair our roof, quickly and for a good price. They were extremely nice and communicated everything. It’s a year later and we are still very happy with their work."

"On Top Roofing is Top of the Line Roofer. Professional delivery with solid quality! Company was hired to correct the issues caused by a prior roofer whose incompetence has cost me additional thousands in repair. On Top Roofing installed a ridge vent that the prior roofer only placed on the roof, re-flashed the chimney where prior roofer failed to install to match new rook lines, re-surface flat rook where prior roofer ignored. In addition, On Top Roofing was used on apartment buildings to help close up the roof and eliminate a bat problem. On the Top Roofing is the only roofing company to use. It takes a while to get on their schedule, but they show when they say the will and do the job they say they will do. Only hire On the Top!! You will not regret."

"The roof was patched and I no longer have a leakage problem, I provided the wrong Shingles which were used unfortunately, and as a result the finished look is relatively poor, The company was very responsive and if they had the correct materials I'm sure the job would have been more than satisfactory. I need to remember it was a patch not a new roof. Try them, they came out between rain storms and fixed my leak."

"- Very prompt, professional service delivered at a great price on our Newton expanded bungalow. - Owner, Brian (in business for 25 yrs) assessed/priced job and, with on-site job supervisor, was available at every stage of job completion. - I requested 4 references which Brian gave me at random but said he doesn't call former customers in advance of such requests so wasn't sure if I'd get call backs. All 4 references DID return my calls and all raved about Roofer's Edge/Siding work and value. - Also, work crew included professional women which I appreciated. - Policy is payment at the end of the job when customer is satisfied. - Will definitely use again for siding and or windows given this roofing experience."

"This team took the time to really understand leaky roof problem before considering the repairs."

"the work was great, he went in their and cleaned up everything, and put in a piece of pad to cover it to keep the birds out; he also checked every part of the roof for any possible entries as well."

"I have to commend these guys and the job they did with my roof. I had a partially collapsed roof from the snow and ice buildup on my roof. I needed the repair done urgently and withing budget. I got may quotes on the job with some outrageous bidding to be honest. Overstate gave me a fair price and told me exactly what needed to be done. Within a week the job was completed and my home is leakproof again."

"It was very nice working with Lou and his team. He responded quickly to my request for a quote. I found his pricing to be fair. He and his team came and installed my roof in one day. The crew put down the tarps to protect my flowers and lawn. When they finished the site was all clean. Lou took the time to explain the details of the quote which I appreciated. He quickly responded to any questions I had . I would highly recommend Lou for your roofing needs. Iâ ve also hired him team to power wash my home. They did a fantastic job- it looks like a new house. I had a lot of moss on the north side of my home. They worked extra hard to get it all removed. After the power wash all the staining from the moss was gone. The crew cleaned up as they worked. Again, if you are thinking of power washing I would highly recommend Lou and his team."
