I called for an estimate on fixing problems reported by my gutter cleaning company. Certified came the next day and informed me that the repairs were unnecessary, and didn't charge me for that or for a minor repair on a downspout.

Certified agents were knowledgeable and efficient. They quickly identified the issue, provided me options at different price points, and completed the repairs the same day. Highly recommend!

These guys are honest, reasonable, professional, and fair. They shared photos of the work each step of the way. They also assisted me with some interior damage that had been caused by my roof issue. I plan to keep them in speed dial as my home ages.

Lesley Ryan

They completed a very tough job in VERY chilly weather. The communication amongst all involved (myself, workers, and those who work in the area of coming out to give estimates, and making/confirming all the appointments, etc.) was excellent.

The new roof is more than just a structural upgrade—it's an investment in safety, efficiency, and aesthetic appeal. It looks fantastic and has transformed the home's appearance. Impressively, the installation was completed in just three days, showcasing the efficiency and expertise of the roofing team. This quick turnaround minimized disruption and delivered a fresh, durable roof quickly. We are satisfied.

The crews showed up as expected, worked diligently through a very cold day to repair the roof that was leaking and returned during a holiday week to finish the gutter and downspouts.

I needed to place some nails in the top rail to pull it up so the windows could open. That was something we should have checked on before they left. Other than that everything went well and they were more than happy to help out and do anything that I asked for within the scope of the project.

Certified Roofing gave estimate for my townhouse and shed roofs.The price and warranty were GREAT.
But that's only the beginning
Tabitha West the office coordinator took over. She set up materials delivery and work crew scheduling. She was amazing. Told crew would start between 7-9 AM They came at 7AM and begin immediately
They were polite and quick. They cleaned up afterwards perfectly
Thanks again to all and especially Tabitha West who really made this easy. Richard Olney, Maryland

This company is absolute joke!!! They made 2 appointments with me the first they canceled the day before the second they called at 9:26 for a 10:00 am appointment and they aren’t showing up again! I drove 3 hours to meet Adam and this is the type of service they give!! Please think about this when you attempt to get an estimate for a huge job!! Don’t waste your time or money!!

Contacted Certified Roofing when I found my HOA would not fix my skylight leak. I saw that Certified was ready to give me an estimate right away. Richard B. came by the next day and did a thorough inspection both inside and outside. After a quick confirmation from the office, Richard provided me with a written estimate. The very reasonable estimate was quickly confirmed, and the job was scheduled. The roof part was immediately repaired by Richard and a fellow Certified employee. Richard explained what was wrong and how they fixed it. We scheduled the inside work (plaster and paint) and Richard thoroughly completed the repair and replastering required. The next day he came by to do the prep work and then the painting.
Each step was efficiently and effectively done.

The employees have been very comfortable and pleasant to deal with. They are professional, very competent and respectful at all times.

If you have a roof problem, I strongly suggest you have Certified Roofing come and provide their services from inspections, estimations, and work completions on time. At least call them before you sign a contract with anyone else.

The 5 stars are for the actual work. However, there was an issue with scheduling. I received an email setting 10/16 as the date. When the roofer did not come on that date I called & was told that the date was changed to 10/18. I was not informed of his change and dad to rescheduled to 10/21 because I was out of town on 10/18.

This is at least my 8th job working with Certified Roofing, each on a different house or part thereof. If you're reading this review, then look no further. I recommend you hire them without reservation. Owner Steve Mitchell and everyone under his command are honorable, hard-working, conscientious, responsive, and use their best efforts to do the job properly the first time. As a more exacting customer than most, they've earned my respect and business time and time again. Go get other estimates, then compare the costs. You'll see their prices are always fair, but their workmanship is superior. They do a better job installing products. They clean up better. The employees will look you in the eye and give you honest answers. They are my go-to residential roofing contractor as long as I have a roof over my head. In this last project, they removed old decking material and worked cooperatively with a window and door contractor I chose to install new decking. The attached photos show the attention to detail they paid to my job to do it right. And when I've had other repairs or rare warranty work, they've responded promptly, and addressed the issue completely. They will sell you a quality product that lasts, and they stand behind their work. Certified has earned my trust.

Michael Robinson-Williams

At 78 yrs of age, we are skeptical of businesses we have no prior relationship with. We received estimates from 3 companies. Certified matched the others but we also heard the owner's testimony. I am a Vietnam veteran and trust his word. It was a slow startup due to shipping delays. Ms. Tabitha was key to being patient. She worked with us every step of the way. As a long-term consumer, I realize some help she provided was over and above her normal duties entailed. The plus factor was the worker's professional demeanor. They began and finished the installation, removed and cleaned up the area. So far, we can't ask for a better result. This winter will be the test.

Thanks CR!

Certified removed our old roof and replaced it with high quality new roofing. Joshua the sales rep was very professional and knowledgeable. Tabitha and Ashley in the office were very helpful throughout the process. We are very pleased with the quality of the roofing and the installation. The job was finished and cleaned up in one day. We would recommend this company.

Don’t bother using a different roofer other than certified. They’re the only ones that have showed up, provided a same day estimate, added my project to the schedule and got it done. Various other roofers were not as attentive and or would ghost. Highly recommend but hopefully won’t have to use them again as my roof is fixed! If I do need roofing needs again they’ll be a the only ones I’ll use.

Real deal Sales
Choosing a qualified company to purchase materials and services for a major need of your home can be daunting. I asked Certified Inc., to come to my house for roofing consideration.
Garrett was the best sales-customer service agent to ever visit my home. He was product knowledgeable and made additional efforts to ensure the information given to me was correct. The workings of a great sales person, but much more than that. Garrett’s pleasant manner was personable, informative and truly instrumental in helping me make important decisions. I enjoyed Garrett’s salesmanship he made the entire process comfortable for me to invest my home with the Certified family.

Fantastic experience with Certified. After a storm, we were in need of a roof repair. Ashley and Marco arranged to have a repair crew out right away. It was a pleasure to work with them. Certified will be the first call I make if I need a roof repair or a new roof in the future. A five star company.

I needed immediate repairs for a couple of areas on my slate roof causing an inside leak. Certified Roofing were the first to respond. Javier promptly showed up. Diagnosed my issues. Repaired it on the spot at a very reasonable cost. I will be reaching out to these guys when I'm ready to completely redo my roof.

Experienced and professional team. Josh Artis came out to the house, showed samples and talked me through everything. He was very patient as we struggled to decide on a color. The crew came out early in the morning and were gone by about 2 pm. They didn't leave even one nail that I could find. The roof is beautiful and not nearly as expensive as we anticipated. Great company!

I had the opportunity to use Certified to replace the siding on the back of my home. Pricing was fair and customer service was great. The project was also completed in the projected time frame and everything turned out perfect. I'd recommend their service.

Rachel McKinney

Over 60 minutes late, unprofessional, no communication or heads up. Do not recommend their services. I do not answer my door or continue with service when companies are clearly not respectful of people's time. Very discouraging since I am a veteran and was hoping to support a veteran owned business.

Omar Arnold

I appreciate how this company works from beginning to end. When I initially called, they sent two roofers to inspect the roof to see if repairs could be made right away. When they saw that it was not the case, they let me know and scheduled me with a member of their sales team about a roof replacement. Their cost happened to come in at the low end of the estimates that I had from other companies. The work was done in a day, with the workers starting about 7:45 and finishing about 3:30. The pictures they provided afterwords show an awesome job.

Nicole Herbele

Certified Roofing is the absolute best company. I had many estimates for my roof and the best price and guarantee came from Certified. When ever I had a question they answer quickly. They also always returned calls right away. When we had Certified do the roof they were fast and efficient. Our roof looks amazing. I highly recommend Certified to everyone who wants excellent service at a great price.

Can’t say enough great things. Tim was an excellent rep and helped me navigate insurance and the process overall.
They were on-time, fast, friendly, did a fantastic job and left everything spotless. They company checked-in on the day of install to make sure things were going smoothly, which they were.

First time having to replace our roof so we were somewhat clueless about the process, options and next steps. Certified was patient and helped guide us without any pressure.

Highly recommend them.

The Craftsmanship of the crew is top notch. I used them for a Cedar Shake roof on a historic house with a very steep pitch. Crew took meticulous care in the quality of the work. This included clean up. I highly recommend certified. Very responsive.

Jaime Cardenas-Garcia

We had a great experience from beginning to end. The estimate of the cost was done in a friendly way, not a sales pitch, fully explaining what was to be done and the certifed quality that was to be employed. When we were ready to get things done, we contacted them for an updated quote, signed the contract that explaned in detail what was to be done. After giving the go ahead, we were scheduled in a short time. They did not accept any down payment to begin and finish the work. The roof installation was done in a day, with the roofing materals delivered the prior day. Instalation personnel were friendly and got everything done in a meticulous and professional way. The cleanup at the end of the day left everything in its place with nothing that needed any further cleanup.

WE WOULD HIGHLY RECOMMEND CERTIFIED INC. ROOFING!!
