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.”

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.
