Quick overview

The best roofing company inBaltimore for YOU

One of the most important parts of replacing your roof is finding a trustworthy contractor who can not only do the work but is helpful and makes you feel comfortable throughout the entire process. After all, a roof replacement is one of the most expensive projects you can take on to improve your home, so you want to spend your money wisely.

When evaluating Baltimore roofing companies, take the time to read reviews from reputable sources and ask friends and family for potential referrals. Doing so will give you a good idea of the quality of a company's work and, importantly, how well they communicate throughout the project. Roofers often leave yard signs by homes after completing a project, too, so look for these in your area and note the quality of the work.

While your budget is always an important factor, remember that the cheapest roofing company isn't always the best option. Always try to get estimates from at least three roofers and note the differences between their warranties, transaction fees and whether they offer financing. Also, take note of their availability, as a small company that's booked three weeks out won't be the best option if you have an emergency on your hands.

The best overall roofing company in the Baltimore area is DWM Roofing . Operating all over the region since 2004, this roofer is experienced in tackling roofing issues common to Baltimore and the surrounding counties. It uses its in-house crews on every job, doesn't require a down payment and offers a lengthy ten-year workmanship warranty. It's also accredited with the BBB with an A+ rating and has nearly perfect review scores across Google, Yelp and Angi.

Brightview Builders is an excellent choice if you have more than just roofing work to do. The company offers several other repair and remodeling services, ranging from home additions to adding porches and decks. It's also BBB accredited with an A+ rating and has fantastic review scores.

Have an emergency? Chesco Remodeling is the company to call because it offers around-the-clock emergency services. It's also BBB accredited with an A+ rating , background checks its crews and has great review scores. Chesco does much more than just roofing, so it's a great alternative if you have several home improvement projects on your list.

Best roofing companies inBaltimore

DWM Roofing is the best overall Baltimore roofing company

Members of the DWM Roofing crew work on installing a new roof

Members of the DWM Roofing crew work on installing a new roof

In business since 2004, DWM Roofing has over 21 years of experience providing roofing and other exterior services around Baltimore and the surrounding counties. Based in nearby Woodbine, Md., DWM has completed thousands of projects in the region, ranging from roof replacements and repairs to gutter and skylight work. Over that time, the company has built an excellent reputation due to its focus on quality workmanship and customer service.

To get an estimate, DWM Roofing requires an in-person inspection, so we weren't able to get a ballpark price. This is the case with all of the roofers on this list, and all roofers must physically inspect the roof before giving a final quote. However, you may come across other companies that can provide a rough estimate of costs based on available satellite imagery of your home, before confirming with an in-person inspection.

Services offered

  • Roof replacements

  • Roof repairs

  • Gutters

  • Skylights

  • Financing

One of the biggest bonuses of going with DWM Roofing is that it doesn't require a down payment to schedule services. Unlike most other roofing companies, DWM Roofing gives you 30 days to pay for roofing work, rather than requiring payment in full the same day. The company accepts checks and all major credit cards, though there is a small transaction fee for card payments. The representative we spoke with couldn't confirm the fee amount, but it's common to see a 2% to 3% surcharge added to credit card transactions.

DWM Roofing offers a 10-year labor warranty on its roof replacement work, which means it will come out to repair any issues that arise due to how the roof was installed at no cost. It only works with shingle roofing, and you get an additional material warranty based on which shingles you select. Typically, these are in the range of decades and cover issues due to manufacturing defects.

A thorough cleanup is part of every job, and several reviews point to how well DWM Roofing does with this aspect of its work. The company can also help you obtain permits for the work if necessary.

DWM Roofing is BBB-accredited with an A+ rating and no registered complaints. It's also highly rated with 4.9 stars on Google (380 reviews) and five stars on Yelp (15 reviews) and Angi (166 reviews). DWM uses its own crews for roofing projects and only uses a subcontractor for gutter replacements. However, it doesn't perform background checks on them.

The company is open Monday through Friday from 8:30 a.m. to 4 p.m. It is closed on weekends. It is located at 518 Mabe Dr., Woodbine, Md., 21797. You can call DWM Roofing at 410-795-7600 or visit its website to request an estimate.

DWM exceeded my expectations throughout the process! David was thorough in explaining everything along the way. There were no surprises. I felt they appreciated my business from start to finish. The crew was outstanding. They were able to complete the entire job in one day. Staying past sunset and scouring for any remaining debris with flashlights! The roof looks great and above all I feel this was done at a very good price. I've never been so happy to spend this much money. I feel my roof is sound for many years to come! - Bob H., Google reviews (⭐⭐⭐⭐⭐)

DWM Roofing has nearly perfect reviews online for a reason. The company places quality workmanship and customer service as its highest priorities.

It doesn't work with metal roofing, but it's a great choice if you need shingle roofing work done.

Brightview Builders was founded by owner Mark vanReuth in 1988, giving it 37 years of experience navigating the issues Baltimore homeowners encounter most with their roofs, siding and much more. VanReuth continues to be heavily involved in the day-to-day operations of the business, meeting personally with each client during the consultation process. That kind of personal touch has led Brightview Builders to gain a reputation as a thorough and trustworthy contractor in the region.

While not every company has its owner answering the phone, we spoke directly with vanReuth when doing research for this list. He was thorough in answering all of our questions, though we weren't able to get a ballpark idea of costs because estimates require an in-person inspection. Again, that's common in the industry, but it's worth noting you can't get an instant estimate via Brightview's website.

Services offered

  • Roof replacements

  • Roof repairs

  • Siding

  • Kitchen and bathroom remodeling

  • Windows

  • Porches and decks

  • Home additions

Brightview Builders offers a one-year workmanship warranty by default on its work, but vanReuth told us he can flex that to three years, so it's worth asking if you call. That's in addition to the material warranties that shingle manufacturers offer to cover any manufacturing defects. To get your project scheduled, Brightview Builders requires a down payment equal to 33% of the estimated project cost, which is common among companies in the Baltimore area.

This roofer accepts checks, debit and credit cards, but there is a 3% transaction fee applied for card payments. Brightview does a thorough job cleaning up, with many reviews noting it as one of the positives of working with the company. It can also work with you to pull permits if the job requires one.

With BBB accreditation and an A+ rating, Brightview Builders is a trustworthy contractor with no registered complaints. It also has a 4.2-star rating on Google (13 reviews), five stars on Yelp (one review) 4.9 stars on Angi (32 reviews). While it doesn't do a background check on its crews, vanReuth told us many of the crew members have been working with him for 15 years.

Brightview Builders is open Monday through Friday from 8 a.m. to 6 p.m. and Saturdays from 10 a.m. to 2 p.m. It is closed on Sundays. The company is located at 924 Baltimore Annapolis Blvd., Severna Park, Md., 21146. You can call 410-647-3100 or visit its website to request an estimate.

Notably, William Mackay Roofing was one of the most pleasant companies we spoke with for this guide, with the representative we spoke with taking the time to thoroughly answer all of our questions.

William Mackay Roofing works with several different types of roofing, including asphalt shingles, metal, rubber and slate. The manufacturer's warranty, which covers factory defects, depends on the type of material you choose.

To get a project on the calendar with William Mackay Roofing, the company asks for a 33% down payment, which is normal for the Baltimore area.

Chesco Remodeling was founded in 2016 by owner Charles Chapman, who used his father's nickname, Chesco, for the company's name.

Now, Chesco Remodeling is known as an excellent choice for everything from roofing to interior remodeling and exterior contracting work in and around the Baltimore area.

Like the other roofers on our list, Chesco Remodeling doesn't provide ballpark satellite estimates to customers until after an in-person inspection. Instead, you'll have to have a company representative come to your home to take measurements and customize a quote to what your roof needs. The company told us, however, that it asks for 33% of the estimated cost as a down payment.

Services offered

Chesco Remodeling is GAF Certified and an Owens Corning preferred contractor, and it offers up to lifetime manufacturer warranties on its products.

That's lower than most of the other warranties from companies on this list, but you should notice any installation issues within the first several months.

For payment methods, Chesco accepts checks, ACH payments, credit and debit cards. There's a 3% fee for card transactions, which can get expensive with roof replacements, so it's something to be aware of. The company also offers financing if you can't pay for services all at once.

Cleanup is included in the job cost, with one review calling it "immaculate." Chesco can also help you pull permits when they're required. If you need emergency services, Chesco has a 24/7 line that you can call.

Baltimore roofing FAQs

How often should I have my roof inspected, and how much do roof inspections cost in Baltimore?

According to Alternative Roofing, one of the top roofers in this guide, you should try to have your roof inspected at least once every two to three years . Outside of regular inspections, it's also a good idea to have one done after major storm events. In either case, the goal is to catch small issues before they turn into large, more costly problems to fix.

Most roofing companies offer free inspections as part of the estimate process if you're considering hiring them for repairs or a roof replacement. However, general inspection costs can run anywhere from $150 to $800, according to EC Roofing , a Maryland-based roofing company. The cost largely depends on the size and complexity of your roof, along with whether you request a specialty inspection with a drone or thermal camera.

For more guidance, read through our guide to roof inspection costs .

How do I know if my roof needs repairs or a full replacement?

Some of the biggest signs your roof may need to be replaced are if you see significant sagging, a large area of missing or damaged shingles or if you have significant hail damage. You might be able to get by with simple repairs if you have smaller issues, like minor leaks or a few missing shingles. The best way to know for sure is to have a reputable local roofing company perform an inspection to spot signs of wear and tear that you might miss.

Trying to budget for a repair or replacement? Check out our guides on the cost of roof repairs and roof replacements for more.

Does homeowner's insurance cover roof repairs or replacement?

Typical homeowner's insurance policies are geared more towards helping cover the cost of repairs or replacements in case of damage from unforeseen events like major storms and fires. If your roof has reached the end of its life or has damage from normal wear and tear related to its age, it's unlikely to be covered by your homeowner's insurance. The best way to find out for sure is to contact your insurance company and read our guide on how to determine if your homeowner's insurance covers roofing damage . Also ask your roofing company about how to get the most coverage from your insurance policy, as they're typically very well-versed in dealing with the claims process.

How long does a roof typically last in Baltimore?

For asphalt shingles, which are the most common and affordable type of roofing, you can typically expect to get between 15 and 40 years out of them, depending on the type, according to Maryland roofer Mars Roofing . Premium materials, like metal and slate, have lifespans that can range upwards of 70 and 100 years, respectively. Cedar shake roofing lands somewhere in the middle, with a typical lifespan of between 30 and 50 years.

With frequent rain and temperatures that range from hot summers to frigid winters, Maryland's climate can be harsh on roof materials of all types. That's why it's important to hire a reputable roofing company that installs quality products.

How much does the average roof replacement cost in Baltimore?

According to Capitol Improvements, a Maryland-based roofing company, the average cost you can expect to pay for a roof replacement is around $15,000, with smaller homes sitting closer to $10,000. For the average 2,000-square-foot roof, pricing will likely range between $15,000 and $21,000. Most homes in Maryland are between 2,000 and 3,000 square feet, Capitol Improvements says.

The biggest factors in your roof replacement costs are the size and complexity of your roof, as well as the materials you choose. More premium materials command a higher price. Likewise, a large roof with multiple structures, such as gables and dormers, will be more expensive.

How long does it usually take to replace a roof in Baltimore, and can you stay in your home during a roof replacement?

Most of the roofers we spoke with for this guide said that you can expect a roof replacement with asphalt shingles to take between one and two days. The larger your home and the more complex its roof is, the longer it can take. More premium materials, such as metal and tile, can take between four days and a week or more, depending on the complexity of your roof.

You can usually stay inside your home during a roof replacement, but you might not want to. That said, installing a new roof is noisy . If you work from home, it might be hard to concentrate while the roofing crew is working. Pets and small children might not do well with the noise either, so it's worth making arrangements for them to be elsewhere if possible.

What is the best time of year to replace a roof in Baltimore?

Generally, the best time to replace a roof in Baltimore (and Maryland in general) is the fall season. Alpha Design Services , a local Baltimore roofing company, says fall is the preferred season because milder temperatures and more favorable weather allow for a more comfortable climate for roofers and a better environment for shingles to set and seal. However, it's also the busiest season, which means you could face difficulty with availability.

Coming in second is the spring season because of its comfortable temperatures, although spring rains can lead to delays. The summer months are a good choice as well, but increased demand can cause issues with scheduling and hotter temperatures may lead to longer install times. Finally, winter is the slow season for roofers, so it's easier to schedule your replacement. However, ice and snow can cause delays and may impact the durability of shingles as they set.

What questions should I ask a roofing contractor before hiring them?

The key to getting a trustworthy roofing contractor is asking the right questions, so it's helpful to keep some in mind. Most importantly, ask about their labor and material warranty policies, which can vary quite a bit between roofing companies. Using subcontractors is common in the industry, but you should ask if they are background-checked. If not, you should also ask if the company has a dedicated crew they have worked with for a long time. When you first call a company, it's also a good time to ask whether they handle permits (if required) and what their cleanup process is like. Always verify a company's licensing and insurance information as well. 

Want more tips? Check out our guide on what questions to ask a roofing company before hiring them.

Is it better to hire a local Baltimore roofing company instead of a national chain?

For most home services, choosing a local company offers benefits over hiring a national chain. In Baltimore, local roofers should be familiar with the seasonal weather patterns and local building codes. If any issues crop up after the installation, they'll also be more readily available to come out and make any required repairs. Local companies also have more riding on word of mouth to gain business, so they have a greater incentive to provide excellent customer service throughout the entire process.

Are there local roofing regulations or permits required in Baltimore?

Baltimore has roofing regulations and requires permits if 50% or more of the roof sheathing or deck is being replaced, according to the Baltimore County website . Roofing companies in Maryland are also required to be licensed through the Maryland Home Improvement Commission. Most roofing companies will be able to guide you through the permitting process if one is required, and they may pull the permits for you.
