With rain water starting to come through my roof, I was in a scramble to find someone to fix my roof as quickly as possible. A friend suggested CJ Roofing and it was the best advice he's given me since i've known.
They were professional and fast, putting in a new roof in a day and a half. Couldn't be happier with the work they did. Highly recommend.

CJ Roofing did an amazing job. We had a skylight leak during the snowstorms this winter and CJ roofing came out, inspected and had a fresh one installed all over a span of three days. Their professionalism, work and speed is very impressive. I would highly recommend them for anyone who needs roofing work in the DMV area.

This is truly a professional and honorable service. I had a roof leak and contacted Charli via email. Within 24 hours he had come to my house (even though I wasnt there; I had a guest staying), he assessed the damage and repaired the damage. What is critical to note is the following. Although most of the leak stopped, there was still a small amount of water getting in so I emailed Charli . He returned to the house within 24 hours, reassessed the situation, and resealed the roof without charge. This is old school honor, service, reliability and professionalism. It is my absolute pleasure to recommend this business unreservedly.

Charlie and his crew are fantastic! We had a leak from some heavy storms, they moved quickly to get out here and help us fix everything. In addition, and greatly appreciated by me, CJ himself came out, invited me up to the roof to show me what they were seeing and talked through his plans. Afterwards, they reinvited me up to look (I passed this time) but also sent pictures of the completed work.
Also, shared his contact with my neighbor who has also been pleased with the work.
Definitely recommend!

CJ roofing is your must select roofer in the DMV. I had multiple roofers provide quotes and CJ was not only the most competitive price by a significant margin but also more honest and straightforward to work and communicate with. He was able to complete the job quickly and I would be happy to work with him again.

CJ Roofing did a great job in replacing the flat roof to my Capitol Hill townhouse. I met with Charlie Johnston a few weeks before deciding on going with CJ Roofing and found him friendly, personable, forthright, honest and professional in providing me advice and guidance as I was trying to determine which roofing company to use. I like the fact that hes local, worked a lot over the many years on these historic townhouses, and is a family-owned business.
He provided me lots of guidance that ultimately led to my selection of his company. His crew led by Hugo arrived early on a Friday 7am and were done by 7pm with the entire tear down, roof prep, wood replacement, laying out the water proof base and insulation, and lastly the white bitumen roof covering. He also replaced all metal around top perimeter and did great flashing work including encasing an old unused chimney. Lastly, his crew did a complete clean up of my backyard for all reuse and materials taken out as part of the tear out. Highly recommend CJ Roofing and Charlie Johnston the owner.

Received a letter from my home insurance. Called CJ Roofing second and he was the first to answer. They came the very next day for evaluation. And immediately scheduled services and were there two days later repairing my home. Job completed, Job well done and I'm a satisfied customer. In fact I have him my word that he will be my go to contractor for my next improvement project. Thx CJ Roofing

Living in a house built in 1915, we've had to hire many contractors over the years, and Charlie and his team are among the best. They replaced our entire roof and added ventilation, and the entire project, from sending the proposal to hammering the last nail on the new roof, took about a week. They actually would have started sooner if not for rain. I'm a worrier to put it mildly, and Charlie promptly and patiently answered all of my questions. The roof is sturdy and looks great, and the entire transaction was seamless and no-hassle. Highly, highly recommend!

Definitely a company that I'll always use and refer for all roofing needs. They are true roofing experts! Performed maintenance on my slate roof at one location at a reasonable price. I was so impressed with the professionalism and workmanship, I immediately sent them to another work site to repair a flat roof. CJ Roofing is indeed an all around professional company who knows their stuff!

Charlie and his team were super responsive when we reached out about a leak in our roof. He and his team prioritized our repair within 48 hours, and at an affordable price. He did not try to oversell us on a complete roof replacement or a bunch of extras. We really appreciate how kind, professional, and efficient working with CJ Roofing was. Hopefully we wont need to contact them for a long time, but we know who to call for any roof issues in the future. Thanks again, guys.

Charles and his team at CJ Roofing completed repairs and maintenance to our roof. We highly recommend CJ Roofing. The process was efficient, scheduling was easy and communication was good. The price was reasonable and workmanship on point. For reference we have a metal roof with a small portion made of rolled rubber. CJ Roofing repaired the seam between the metal and rolled rubber. In addition, they recoated the entire roof with fibered aluminum, repaired a few slate shingles on the mansard and installed a missing gutter downspout.

I highly recommend CJ Roofing, LLC for any roof repairs you may need! We have had a leak around a vent on our roof for about a year after paying two different contractors to fix it. We were extremely frustrated with the past service provided and were in search of a reliable roofing company. I initially reached out via email and got a response the same day. Less than a week later Charlie stopped by to inspect the roof and provide an estimate. He truly went above and beyond, listening to my concerns, took a photo of the issue, explained what needed to be done, and provided an estimate at that visit. The very next day his team came and fixed the issue! Additionally, his team took pictures of the process and finished project. We so appreciate your responsiveness, professionalism, and detail. Might I add, the whole process from reaching out to repair was 1 week! We will definitely be coming to CJ Roofing with any future roofing needs! Thank you!

Recently bought a new home with my family. Its nearly 100 years old and needs lots of TLC. One of the first things we wanted to do post purchase was make some repairs to the roof and fix up the homes wonky gutter system.
I always do my homework, so I got a bunch of quotes for the work from reputable local businesses. Charlie was one.
The other roofers heard slate and saw dollar signs. Without even bothering to examine my roof, they tried to sell me on full replacement. It doesnt need one.
Charlie was honest, professional and straightforward. I sensed sincerity. So I went with Charlie and I have no regrets.
This is the way you earn repeat clients. Textbook case.
Highly recommend.

CJ Roofing repaired my roof, and the done a great job! Im very pleased and happy to provide them with a review because they done exactly what they said they would, and unlike other experiences Ive had with contractors, the price I paid was the same as the one the quoted before work began. A breath of fresh air. Thanks Charlie!
