A roof replacement and a careful search for stray nails recur in customers' accounts of Conde Roofing & Construction. An August 2026 Google reviewer said Lonnie inspected their roof in person, Katie and Alex explained the schedule and work, and the crew replaced the roof in a day. Alex arranged three passes around the property to check for nails because the household had children. A May 2026 customer separately praised Alex for checking cleanup so their dog would not be hurt by old nails. Conde describes itself as a family-owned Merrimack roofing and siding contractor serving southern and central New Hampshire and northern Massachusetts. It offers residential and commercial roof replacement, repair and inspection, along with siding, skylights, ice dam treatment and insurance-claim work. The company states CertainTeed ShingleMaster Premier and Velux skylight-installer credentials. It is BBB-accredited with an A+ grade; Google lists five stars from 248 ratings. Customers describe roofing decisions as well as installation. An August 2026 reviewer said Lonnie explained shingles, flashing, water shield and valleys before the crew replaced decking, shingles and skylights in about eight hours. A June 2026 condo-association reviewer said Tyler O'Brien answered questions about winter ice buildup, discussed possible options and supplied a written recap without pressuring the association into immediate repairs. A July 2026 reviewer said Conde's replacement quote was the lowest of four they received and the roof was completed in one day. Siding work is also described directly. In August 2026, a homeowner praised a full-home siding renovation, work on rear gutters and new garage windows, with Tim managing the site. The customer said communication and cleanup were handled well. Other customers reported problems. In July 2026, a one-star reviewer said a roof replaced about a year earlier had pieces falling off, lifting shingles and improperly installed metal. A March 2026 siding customer said the finished siding looked good overall but described a missed start date, updates they had to chase, two broken outdoor light fixtures they paid to replace, a siding section requiring repair and incorrectly reinstalled gutters. They also reported repeated unanswered calls about proposed interior work after trim had been removed around three windows. A February 2026 reviewer said their grandmother paid $600 for roof snow removal but was told the company did not handle ice dams, contrary to its advertised service. In a June 2025 Manchester Reddit thread, a commenter recommended Conde out of Merrimack, describing fast work, cleanup, attention to detail and one of the lower quotes they received.
“Conde roofing out of Merrimack did mine. They were fast, efficient, and did a great job cleaning up afterwards. They were very attentive to detail and one of lower quotes we got.”
“Conde Roofing & Construction, LLC of Merrimack, receiving the award for small business”
“At Conde Roofing & Construction, the work is never really about roofs. At least, that's how owner Mel Conde sees it.”
We had a roof that was easily 25+ years old. Lonnie came out and made sure to look over the roof when assessing. No AI estimated images or looking at Google Map views. He actually went and inspected the roof unlike some competitors. Then when the week led to the roof job Katie and Alex (the Production Manager for our roof) made sure that everything was communicated to us directly and gave us straight forward answers to timeframes and what was going to be done. In a day we had a brand-new roof, and it looks fantastic Alex saw that we had kids and made sure his crew made 3 full passes around to make sure there were no nails. They were honest, and did great work. I would recommend them again to anyone.
Excellent job came on time and had whole roof done by 4pm looks Beautiful
Great experience with Conde roofing. Last week Lonnie, their lead estimator, came out, heard and acknowledged the ice dam problems we have had the last few winters on our 22 year old roof with 40 year old skylights that we felt needed replacing. In an 10 minute educational moment he explained the hardy New England features of the CertainTeed shingle product, flashing, temps and water shield, ridge caps and metal to all valleys on our roof. Conde was the 3rd quote we received with what we felt was the best option for reducing ice dams, the excellent reviews they had so we signed on. A week later the Conde team was out tearing off the old roof and replacing decking, shingles, and skylights. Everyone was professional, efficient and it was an impressive team to watch during the 8ish hours it took to complete the project. They cleaned up along the way and did an efficient nail/ metal pick up afterward. Communication at all times with Lonnie, and Katie at the office to sign contracts and ask questions was impeccable. We definitely recommend their company to take good care of your concerns and roof.
From start to finish Conde executed and delivered as promised on my full home siding renovation, the quality, care and attention to detail was remarkable. They also took care of the back of the home gutters and new garage windows, timing and communication was clear and consistent. Tim the project manager on site is a irreplaceable asset to the company and truly a perfectionist. clean up around the home was done incredibly well. All said, we could not have asked for a better result and it is Clear Conde provides an extremely high level service and exceeds all metrics. The Value with Conde cannot be replaced and I will make sure I continue to recommend them to anyone in search of work on their home’s Thank you again, Kyle
I hired Conde to install a cupola with a weather vane on my garage. The crew, ably led by Chad, arrived in a timely fashion and got to work. They were professional and very courteous, wanting to make sure I was satisfied. This type of job is tricky, as even though it is not a big one, the details matter. They also insisted that I give them a call in case any issues arise. Katie in the office, was excellent in terms of communication and follow up. Very impressive, and I highly recommend.
