As a homeowner in Puyallup, Tacoma, WA, or surrounding areas, you might consider adding a shed to your backyard for additional storage space. Flat-roof sheds are a popular option due to their modern aesthetic and ease of construction. But before you decide on a flat-roof shed, it’s important to weigh the pros and cons to ensure it meets your needs.

In this blog post, we’ll explore the multiple pros and cons of flat roof sheds so you can make informed decisions.

 

Advantages of Flat Roof Sheds:

Cost-Effective Flat roofs are generally less expensive to construct than pitched roofs. This is due to two main reasons:

1. Simpler Design: 

Flat roofs require a simpler framework than the trusses and rafters for a pitched roof. This translates to less material and less labor during construction, leading to potential cost savings.

2. Material Efficiency: 

Flat roofs use less material overall. Their angled surfaces don’t require complex roof decking or extensive underlayment, which is needed for pitched roofs.

3. Modern Design:

Flat roofs offer a clean and contemporary aesthetic that can be a major advantage for homeowners in Puyallup, Tacoma, WA, and nearby locations. These areas boast a significant number of modern and mid-century modern homes. A flat roof shed can seamlessly complement the architectural style of these residences, creating a cohesive and visually appealing property.

4. Usable Space: 

Unlike pitched roofs with sloped surfaces, flat roofs create a usable space on top of the shed. This additional space can be utilized in several ways:

5. Storage: 

The flat roof can provide additional storage for bulky items that might not fit inside the shed, such as firewood, kayaks, or patio furniture.

6. Rooftop Deck: 

With proper reinforcement and safety measures, a flat roof shed can be transformed into a functional rooftop deck. This can be a great way to create a private outdoor space for relaxation or entertaining.

7. Green Roof: 

For the environmentally conscious homeowner, a flat roof shed offers the opportunity to install a green roof. A green roof is a vegetated layer on top of the roof that provides numerous benefits, including insulation, stormwater management, and habitat creation for pollinators.

8. Improved Drainage (with proper design): 

While drainage can be challenging for flat roofs, it’s not insurmountable. Flat roofs can be designed with a slight internal slope that directs water toward strategically placed drains. Our team at South Sound Structures can ensure your flat roof shed is built with the proper drainage system to prevent ponding and potential leaks.

 

Disadvantages of Flat Roof Sheds:

1. Drainage Issues (if not properly designed): 

As mentioned earlier, proper drainage is crucial for flat roofs. If not designed and constructed correctly, water can pool on the roof surface, leading to several problems:

2. Leaks: 

Ponding water stresses the roof membrane, increasing the chance of leaks developing over time. Constant moisture exposure can also deteriorate the adhesive holding the membrane in place.

3. Mold Growth: 

Moisture buildup from ponding water creates a breeding ground for mold. Mold can damage the roof structure and pose health risks to those who use the shed.

4. Roof Deck Deterioration: 

Over time, ponding water can lead to rot and decay of the underlying roof deck material. This can compromise the structural integrity of the shed and require costly repairs.

5. Limited Ventilation: 

Flat roofs can trap heat and moisture, especially in hot and humid climates. This can lead to an uncomfortably hot shed interior during the summer months. Proper ventilation is essential to prevent condensation and mold growth. While flat roofs can incorporate vents, they may not be as effective as the natural ventilation provided by the angled planes of a pitched roof.

6. Snow Load (in areas with heavy snowfall):

Flat roofs may not be suitable for areas with heavy snowfall. The weight of accumulated snow can stress the roof structure significantly, potentially leading to roof collapse if not removed regularly. Flat roofs can still be a viable option for homeowners in Puyallup, Tacoma, WA, and nearby areas, which experience occasional snowfall but not heavy accumulations. However, those in areas with frequent heavy snowfall may want to consider a shed with a pitched roof for better snow-shedding capabilities.

By carefully weighing the advantages and disadvantages of flat roof sheds and considering your specific needs and climate, you can choose the best roof style for your Puyallup or Tacoma, WA, property. 

South Sound Structures has extensive experience designing and building sheds, including those with flat roofs. We can help you explore your options and ensure your new shed is functional, aesthetically pleasing, and built to last.

 

What are the pros and cons of a shed roof?

Shed roofs, also known as mono-pitch or lean-to roofs, are a type of pitched roof with a single slope. They offer some advantages over flat roofs:

  • Better drainage: 

Shed roofs have a natural slope that allows for better water drainage, reducing the risk of ponding and leaks.

  • Improved snow shedding: 

Shed roofs shed snow more effectively than flat roofs, making them a better choice for areas with heavy snowfall.

  • Ventilation: 

The slope of a shed roof allows for natural ventilation, which helps to regulate the temperature inside the shed.

However, shed roofs also have some drawbacks:

  • Less usable space: 

Compared to a flat roof, a shed roof offers less usable space on top.

  • Aesthetics: 

Shed roofs may not be as aesthetically pleasing as flat roofs for some modern homes.

 

What is the most common defect in a flat roof?

According to the National Roofing Contractors Association, ponding water is the most common defect in flat roofs. This occurs when water doesn’t drain properly from the roof due to improper design, low slopes, or clogged drains. Ponding water can lead to several problems, including:

  • Roof leaks: 

Over time, ponding water can seep into the roof membrane and cause leaks.

  • Mold growth: 

Moisture trapped under the roofing material can create a breeding ground for mold growth.

  • Structural damage: 

The weight of ponded water can put stress on the roof structure, leading to cracks and sagging.

 

What is the weakness of a flat roof?

One of the main weaknesses of a flat roof is its vulnerability to ponding water. As mentioned earlier, flat roofs lack a natural slope for water to drain, which can lead to several problems if not addressed properly. Top flat roof shed builders in Tacoma, WA, reveal some ways to mitigate this weakness, including:

  • Proper roof pitch:

Even a slight pitch (as little as 2-3 degrees) can significantly improve drainage on a flat roof.

  • Drainage system: 

A well-designed drainage system that includes scuppers, drains, and gutters can help to channel water away from the roof.

  • Roof maintenance: 

Regularly cleaning gutters and drains and removing roof debris can help prevent ponding water.
