ASPHALT SHINGLES

Asphalt shingles are the most common and most affordable type of shingle found in the DC metro area. They are composition shingles, meaning they are a combination of asphalt, paper, crushed rock, and fiberglass compressed into a highly durable shingle strip. Asphalt shingles are light-weight and can be very cost-effective. Many choose these shingles not only for their lower cost, but also for their wide variety of styles and colors, enabling you to reduce costs without compromising on aesthetics.

When you choose these shingles for your roofing work with us, you will be working with a Certainteed Select ShingleMaster: the top 1% of roofing professionals according to the manufacturer. You will have full confidence in your roof installation knowing it was done by one of the best roofing contractors in the nation.

CEDAR SHAKES

Cedar shakes and shingles have been used on roofs for hundreds of years and have definitively proven their durability in all climates. They contain oils that make them naturally rot- and insect-resistant, which extends their lifespan significantly. However, their longevity is ultimately determined by the quality of the roof construction. There must be adequate ventilation to avoid the build-up of heat, moisture, and ice damming. We recommend installing pressure-treated shakes in Maryland due to the humidity.

Certified Roofing is a member of the Cedar Shake & Shingle Bureau, which means we strictly adhere to the best practices set forth by this major authority in cedar product installation. This credential enables us to offer the best cedar shake warranties in the roofing business. Roofers who are not an approved installer will not be able to offer a material warranty from the Bureau.

FLAT ROOFING

Flat roofing, commonly referred to as low slope roofing, is often found on row houses, office buildings, carports, and porch roofs throughout the DC metro area. We have the expertise to install the following flat roof materials:

Modified Bitumen (torch down)
TPO
EPDM
PVC
Flat Seam Copper
Standing Seam Metal

Our roofers have been trained by the major manufacturers of flat roof products such as Firestone, Mulehide, and Sarnafil. We recognize that flat and low slope roofing installation requires extra knowledge and care, and we have taken every step to ensure that we offer unparalleled service to our valued customers.

Synthetic Slate Shingles

Synthetic slate shingles are well-known and loves for their beautiful, natural appearance and high level of protection for your home. They boast both curb appeal and practicality. They are also freeze-resistant and are a low-maintenance roofing material. If you are looking for a long-lasting, aesthetically pleasing shingle, synthetic slate may be a great choice for your roof.

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.

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!MRW &BCW

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 SalesChoosing 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.A.D W-Ford

Great new Certified roof, good job by the roofing team. I really appreciate how fast they did the work, and also the careful clean up. Sales rep Joshua Artis knew his subject, carefully explained the options and was a big support through the process.

Greg Lund

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.

Professionally and expertly done

Rachel McKinney

12:59 11 Mar 24

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.

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.

We worked with Shawn Mallory at Certified Inc and it was, overall, as smooth and painless an experience you could get from one of the more stressful renovations you could have to do. Overall, Certified Inc offered the best warranty we found for our dollar, and we're really happy with our roof.

This was a great experience for me! Certified Roofing kept up with me, the crew who did the roof was great and did a great job cleaning up as well. I would totally recommend them for a roof job!

John Lee

I had a really great experience. Josh sat down and explained everything I needed, everything I was going to get, and everything were going to do. The bonus was that what was described was my actual experience. From the constant contact to images of work done, all the way through the check-up after the work was done, it was a truly professional experience.

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

15:32 17 Mar 22

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!!
