A gambrel metal roof is a style of roof that combines the best of both worlds - the classic look of a traditional gambrel roof and the durability and low maintenance of a metal roof. This type of roof is characterized by two slopes on each side, with the lower slope being steeper than the upper slope.

The gambrel metal roof style is perfect for homes with multiple stories, as it allows for more living space while also providing a unique and stylish exterior look. This style of roof is also great for homes in areas with heavy snowfall, as the steeper lower slope allows snow to slide off easily.

One of the key benefits of a gambrel metal roof is its ability to withstand harsh weather conditions. According to our article, metal roofs can last up to 50 years or more with proper maintenance, making them a great investment for homeowners.

The classic American gambrel roof is a traditional choice for metal roofs, with a symmetrical layout of two gables and two double-sloped sides. It's a timeless design that works well with metal roofing materials.

An asymmetrical gambrel roof is another option, where one side is extended outward to create an extra room or outdoor area. This design is perfect for homes with limited square footage.

There are also wall-supported gambrel roofs, which don't extend past the walls, saving time and money on eave construction. And, of course, there's the mansard gambrel roof, with four sides and characteristic dormer windows.

  • Classic: symmetrical layout of two gables and two double-sloped sides
  • Asymmetrical: extended side for extra room or outdoor area
  • Wall-supported: meets walls at an angle, no eaves needed
  • Mansard: four-sided with dormer windows

A Classic Barn

Barns are perhaps one of the most common structures where gambrel roofs are used.

The design of a classic barn with a gambrel roof allows for maximum utilization of space.

This makes it an efficient choice for both old and new barns.

Gambrel roofs are particularly well-suited for barns because they provide additional storage space under the roof's second slope.

A shed is a great place to start with a gambrel roof, as it's simple to construct and can really make the most of the space available. A gambrel roof can maximize space in a shed, making it a worthwhile option to explore.

Sheds can benefit from a gambrel roof's excellent drainage properties, which can help prevent water damage and keep the structure dry.

You can choose a wide range of materials for a gambrel-style roof, giving you the flexibility to match your shed's style and budget.

A gambrel metal roof is a great choice for homeowners who want a unique and functional design. This style of roof offers a lot of benefits, but it's not without its drawbacks.

One of the main advantages of a gambrel roof is its extra space. By building a loft close to the rafters, you can create a nearly full-sized room rather than a confined attic.

Its versatility is another plus. A gambrel roof can be adapted to various architectural styles, making it a great choice for homeowners who want a distinctive look.

A gambrel roof is also relatively affordable to construct and maintain. In fact, it's one of the simplest roof styles to build, which can save you money on labor costs.

The understated elegance of a gambrel roof adds character to any building, making it a popular choice among homeowners.

However, a gambrel roof does require regular maintenance to ensure there are no problems or damages. This can be a drawback for homeowners who want a low-maintenance option.

Additionally, a gambrel roof may not be the best choice for locations prone to severe weather. Snow and wind can impose pressure on the building, increasing the likelihood of cracks and leaks.

Here are some key pros and cons to consider:

  • Extra space
  • Versatility
  • Affordability
  • Uncomplicated design
  • Aesthetics
  • High maintenance
  • Low resistance to severe weather
  • Poor ventilation

Potential Drawbacks

A gambrel metal roof can be a bit more high-maintenance than other options. Cleaning gutters and maintaining this roof can be a challenge with all those angles and surfaces.

You'll need to be mindful of the weight it can hold, especially in snow-prone areas. It might not hold as much weight as other roofs, which could be a problem.

The build process is still more complex than a regular gable roof, so be prepared for a more involved installation. While it's simpler than some, it's still a bit more complicated.

In really windy places, the tall sides might not hold up well during storms, so make sure to consider the local weather conditions.

Installation and Maintenance

Installation of a gambrel metal roof is a relatively straightforward process, but it does require some planning and preparation.

The roof's unique shape and design make it essential to ensure that the underlying structure can support the weight of the metal panels, which typically range from 1.5 to 3 pounds per square foot.

A gambrel metal roof can be installed over an existing roof, but this requires careful consideration of the underlying structure's integrity and the potential for water damage.

The panels are usually installed in a pattern of overlapping rows, with each row overlapping the one below it by at least 2 inches to ensure a watertight seal.

Regular maintenance is crucial to extend the lifespan of a gambrel metal roof, with cleaning and inspections recommended every 6 to 12 months.

An Attached Garage

An attached garage can add value to your home, with a gambrel roof adding an interesting visual dynamic.

Even if your house sports a standard gable roof, a gambrel roof for your attached garage can make a big difference.

You can choose from various garage door styles, including hinged, sliding, and rolling doors, each with its own set of benefits.

A standard gable roof is a classic choice for garages, but it's worth considering other options to create a unique look for your home.

Garage doors come in a range of materials, including wood, steel, and aluminum, each with its own pros and cons.

A gambrel roof can also provide additional storage space, perfect for those who need extra room for tools or other equipment.

Regular maintenance is key to keeping your garage door in good working order, including lubricating hinges and rollers every 6-12 months.

You'll also want to check the door's balance and alignment regularly to ensure it's operating smoothly and safely.

A well-maintained garage door can last for decades, making it a worthwhile investment for any homeowner.

Continue Sheeting

Now that the top sheets are nailed into place, we can start finishing the sheeting on the roof. The goal is to make sure the roof is square, which is crucial for its stability and overall structure.

To achieve this, we need to stagger the panel joints for strength. This means panels should be nailed 8 inches along the perimeter and 12 inches in the field or inside trusses.

Staggering the joints is a simple yet effective way to add extra support to the roof. By doing so, we can ensure the roof can withstand various weather conditions and last longer.

The next step is to finish the sheeting on the first side, then do the opposite side in the same manner. This ensures a symmetrical and even finish.

Venting and Overhangs

Venting and overhangs are crucial components of your gambrel shed's roof. Installing upper end paneling on both ends of your shed can help with ventilation.

Gable end vents can be placed on both ends, close to the ridge, or a ridge vent can be installed for effective ventilation. I've found that gable end vents work well, especially in areas with high winds.

Overhangs can be constructed of 2x6's laid flat or toe-nailed on edge, which are called fly rafters. This method provides a sturdy base for your overhangs.

Alternatively, you can create ladder assemblies by nailing 2x4 struts between two trusses and then attaching them to the outside shed ends. This method allows you to install overhangs before your roof sheeting is put down, which can add strength to your shed.

Sheeting the overhangs and adding corner blocking and side overhangs are the final steps in completing your overhangs.

Remove

Removing a gambrel roof can be a complex process, but it's essential to do so safely and efficiently. They permit snow to accumulate because of their flat tops, which can be too much weight for the roof in the worst-case scenario.

You'll need to take precautions to avoid damaging the underlying structure. Water flows off a gambrel roof quickly and easily, but this can also make it more prone to damage during removal.

It's crucial to consider the cost and time involved in removing a gambrel roof. They are more expensive than gable roofs because they cover somewhat more square footage.

Frequently Asked Questions
