Flat Roof Roofers in Northern Maryland

What is a Flat Roof?

A flat roof is one of the first types of roofs ever built by humankind. These roofs allow the top of the home or business to function as walkable space, or they may be slightly pitched and optionally used as a base for what is known as green roofing, where native plants are added to the top of the roof to minimize water damages and provide space for local ecosystems.

In addition to adding potential entertaining space to the home, flat roofs are a particularly energy-efficient option that provide a lot of insulation and minimize the need for an attic space.

What Are Flat Roof Roofers?

Flat roof roofers are like any other roofer, except they are experienced and skilled in working with flat roofs as well. At Harford Roofing & Exteriors, we can help you maintain a flat roof in a way that meets your needs and budget, while improving your home’s energy efficiency and overall curb appeal.

Flat roofs are becoming a common addition to many Maryland homes, but it’s important to choose a roofer whose particularly experienced with flat roofs to install and repair the structures, as they come with different maintenance and inspection needs than a typical shingled and pitched roof might.

No matter your choice of material and level of pitch, Harford Roofers is here to help you make the most out of your roofing experience in northern Maryland, providing services and solutions that will last a lifetime.

How Long Does a Flat Roof Last?

For the most economical type of flat roof, often known as TPO membrane or PVC membrane flat roofs, you can expect it to last anywhere from 20-25 years.

This is very similar to the lifespan of the most economical pitched roof, and that’s because the materials go a long way in determining the lifespan of the structure. Other materials of flat roofing, such as EPDM roofing membrane, will last closer to 25 to 35 years.

Additionally, frequent maintenance and prompt repairs by experienced flat roof roofers extend the lifespan of your roof, ensuring it lasts as long as possible. By taking proactive care of the roof and ensuring it is properly drained and cleaned, you will extend its lifespan significantly.

Are There Any Disadvantages of Flat Roofing?

Particularly in Maryland, it’s important to ensure flat roofs are also shoveled free of snow and have the waterproofing inspected and if necessary, re-sealed before winter arrives.

Flat roofs are not typically durable snow-bearing structures, and while they can add a lot of living space and luxurious options for the modern home, this is one of the main disadvantages that flat roofing has when compared to pitched roofs.

Fortunately, the typical Maryland winter is not typically heavy enough to cause damage to the roof structure, as light coatings of snow throughout the winter is something that a flat roof can endure. On the other hand, several feet of snow for several months, as is common in far northern climates like Canada and northern Maine, will require frequent snow removal.

For the common northern Maryland home or business, however, keeping the home heated and being aware of any water ponding issues is typically enough – along with regular maintenance by flat roof roofers.

Benefits of a Flat Roof

There are many benefits to a flat roof that are convincing, particularly when switching from a pitched roof:

1. Lower construction and repair cost
2. Versatile space
3. Energy Efficiency
4. Less Disruptive Installation and Repairs
5. More Efficient Solar Paneling
6. High Durability
7. Higher Curb Appeal

Overall, the benefits of a flat roof often outweigh any problems or disadvantages because repairs are not as disruptive, as well as safer for the repair crew which lowers labor costs.

Flat roofs are a much more efficient, versatile space that gives you more square footage to the home as well, providing you with an additional space on the home that raises curb appeal and saleability of the home in the future. Flat roofs are the modern way to have fun with your home remodeling.

Flat Roofing Repair

Repair is an important part of any flat roof. Not only do you need frequent inspections to ensure everything is draining properly, but you’ll also need to remove debris and snow periodically to ensure it does not collect and sit on the roof for a long period.

Keeping your flat roof for a long time – or any roof for that matter – is all about maintenance. (1)

“It’s all about maintenance. Once a year, you should clean the cobwebs and dust from your ventilation system and exhaust vents. Then, caulk with a high grade sealant around pipes and vents and paint any exposed metal to prevent rust.”

—Huffpost.com

For when your flat roof is damaged or does require repairs – such as when it’s not draining properly or has cracking from worn-out coatings, it’s important to repair promptly by calling your trusted flat roof roofers. Letting known issues accrue and last can be detrimental to the overall longevity of the roof, as well as make these issues worse the longer they go without repair.

Flat Roof Problems

Every roof will encounter its own set of problems, but there are a couple of problems that flat roofs will encounter more commonly than other types of problems:

1. Pooling water, also known as “ponding” water
   Ponding water is an important warning sign of problems occurring with the roof. Ponding water can be a result of improper installation, or if it occurs over time, poor sloping due to settling in the roof’s pitch. Flat roofs must be slightly sloped and provide enough drainage to prevent water from pooling in areas, accruing leaks and sagging if left unaddressed.
2. Punctures, splits, and tears
   Because a flat roof has very little pitch, it is more susceptible to damage as the object’s impact is absorbed in one spot, rather than it rolling off or being deflected away from the roof. Strong storms and particular types of debris (such as tree branches) can cause punctures, splits, and tears. Fortunately, these are also easier and less expensive to patch and repair than a pitched roof.
3. Structural movement and settling
   Particularly in areas where there are hot summers and cold winters, structural movement or settling can occur in flat roofs. Similar to house foundations, flooring, and other structures in and around the home, settling occurs as a result of natural thermal expansion. Splitting, shrinking, and cracking are common problems that occur when the roof has experienced structural movement.
4. Debris
   Debris must be periodically removed from flat roofs. Debris might include leaves, pine needles, seeds, nuts, or other materials. It’s important to ensure this is removed from a flat roof so it drains properly, and does not clog existing drains.
5. Blistering
   Blistering is a problem that occurs when the roof’s membrane deteriorates, resembling a sort of cracked leather look. These problems can occur when over-exposed to UV light, or if the insulation has become saturated with water. This can be fixed and caught ahead of time with regular inspection.
6. Shrinkage
   A lot of roof materials experience shrinkage over time. Seams de-laminate and small openings form, which is why its critical to get regular maintenance and inspection.

Flat Roofing Repair vs. Flat Roofing Replacement

With any type of roof, you will have to face a decision at some point whether to repair the roof, or completely replace it. Typically, this comes down to the history of repairs and weighing that cost with the cost of full replacement. While flat roof repair is costly, it isn’t nearly as expensive as specialty roofing for pitched roofs. (2)

“Most of the flat roof repair cost is concentrated around labor costs. Up to 70% of the total cost of flat roof repair will be devoted to labor charges. On a per-hour basis, you’ll pay between $50 and $80 per hour to repair a flat roof.”

—Forbes

Ultimately, when it comes to repairing or replacing your flat roof, good maintenance will prevent you from having to replace it sooner than it needs. When the repairs become more frequent and costly than replacing the roof entirely, it may be time to get a new one.

Repair Warning Signs and Maintenance Tips

1. Frequent Roofing Inspections
   Regular roof inspections are an essential part of owning a flat roof. Flat roofs are economical and beautiful, adding space to the home, however, they need to be maintained as there are problems that can go unnoticed easier than a pitched roof, particularly if there is no roof access.
2. Remove Debris
   It’s natural for flat roofs to accumulate debris such as pine needles, leaves, nuts, and seeds over the year. Just like raking the yard, a flat roof needs additional work to ensure there is no debris that collects on the roof every year. This can cause drainage problems and rot across the roof, lowering its longevity.
3. Remove Ponding Water and Snow
   Ponding water is a common issue if your roof is not draining properly. This can occur as the roof settles naturally over time, as well, which is why regular inspections are so important. Additional drains and tapered areas can resolve ponding areas but must be done by a professional. To address ponding water, shop vacs are often used for temporary relief. Likewise for tough Maryland winters, snow must be removed promptly as it can add a large amount of weight to the roof and accumulate water as it melts.
4. Maintain the Flashings
   The flashings of the roof ensure every seam is protected from UV and water damage. These create waterproof barriers around vents, chimneys, skylights, and other openings that could allow water in or collect debris. Every year or so, inspect the flashings and replace damaged ones to maintain a proper seal around these areas of the roof.
5. Waterproofing
   Adding waterproofing to a flat roof is essential. Every couple of years, waterproofing and other roof coatings such as UV resistance can fade with general wear and tear. It’s important to have these coatings done again to ensure the longevity of your roof.
6. Documentation
   One of the most important things about maintaining a flat roof is the need for documentation. This will allow any roofing professional to see how well the roof has been maintained, and potentially catch onto warning signs for repair needs.
