Mo from Greentech arrived on time but did not bring a ladder to look at the roof, saying it was too wet to do so. He then said I should get a pitched roof (versus replacing the flat roof with suitable material). He did this without even looking at my roof. I never received a proposal from him.

Review by Lin C. in Boyds, MD
Project: Install or Replace an Asphalt Shingle Roof
I hired GeenTech for re-installing the whole roof. Spent over $10,000, However a heavy rain caused a big leaking. The contractor, Mr. Mou denied it was due to their lousy work with broken trim between roof and siding. I am forced to seek legal assistance. Mr Mou is misleading the readers. Can you confirm the water damage is not due to your lousy roof works? You can not!!!. You will get an letter from my lawyer. For all other, wait how Mr. Mou will treat you when some issues come up with their works!
Response by Greentech Remodeling: Greentech Remodeling stands behind our work and the warranties we provide to our customers. After the roof inspection, we determined that the leak has nothing to do with the roof installation or flashing and that it was due to the existing old trim and siding. The customer has hired a 3rd party inspector, which determined that the siding has to be repaired or replaced. in order to fix the leak. Greentech Remodeling did not install the siding or the trim at the house and will not be held liable for work we did not complete. Customer is trying to have Greentech pay for repairs, which his own inspector determined were not caused by the roof installation.

Review by in Leesburg, VA
After viewing several company's presentations on a replacement roof, I sat with Mo at GreenTech thinking I already had a company in mind to do the work but had made the appointment so go ahead, grit teeth and listen. I already knew everything I needed to know about roofs and different manufacturers and considering our circumstances of selling the house in a couple of years frankly was not into the warranty aspect. We needed a new roof done with respectable contractors! The price quoted by Mo was extremely fair as compared to other's quotes but based upon price I really could have gone with other's because all in the same range but Mo encouraged me to do my research online and at the end of the day, customer service reviews won because I am the type of people who believes in customer service. Anyone can do a great install right but there are always little things and how a company handles these issues after an install is extremely important to me. Roof install day dawned and the workers were on time, which the company had communicated beforehand. The workers were efficient, professional and met my expectations but daylight this time of year to do a roof our size is not enough. My one complaint is that I was not told the roof was not complete and that cleanup was not finished because really impossible in the dark to do so ...I could adjust. Next day I called because no one there to complete the roof mid-morning as I was picking up nails in the yard and the owner assured workers would be there soon and indeed they arrived as promised to finish. Then a little snafu came about and Mo left his appointments 45 minutes away to come personally to rectify the situation and be on hand to make sure everything met my expectations to include ripping out and replacing a small section of roof because I didn't think it up to standards. Quite unbelievable in todays' world. Mo is a man of integrity and a man of his word. Based upon my experiences I will be doing more work this with company and appears to be a company with integrity and one which has won my trust.
Response by Greentech Remodeling: Thank you again for choosing Greentech Remodeling for your home improvement needs. We truly appreciate your review and your kind words!
