The functionality and efficiency of a building greatly depend on the type of roofing that is chosen when it is being built or renovated. Hangars with gable or rectilinear roofing are common, especially those used for industrial or storage purposes. You can choose the roofing type that best meets your needs by being aware of the key distinctions between these two types of roofing. Let’s examine the main differences and factors to take into account when choosing the right kind of roofing for your hangar.
Perhaps the most common and traditional type of roofing is gable roofing, which is distinguished by its triangular shape created by two sloping sides coming together at a middle ridge. Effective water drainage, lots of room for equipment or storage, and superior ventilation are just a few benefits of this design. Gable roofs are a popular option for many applications because they are also reasonably simple to build and maintain.
Conversely, rectilinear roofing, sometimes referred to as flat roofing, offers a clear alternative because of its simple, horizontal design. Rectangular roofs have their own advantages over gable roofs, despite not having the same dramatic pitch. They maximize the amount of space that can be used inside and outside the hangar, have a sleek and contemporary appearance, and could be less expensive to install—especially for larger structures.
It’s critical to take your hangar’s climate, intended use, budget, and aesthetic preferences into account when choosing between rectilinear and gable roofing. Because they have effective drainage and are resistant to snow accumulation, gable roofs perform well in regions that experience high rainfall or snowfall. On the other hand, areas with milder climates or those where making the most of interior space may be better suited for rectilinear roofs.
Additionally, consider the particular needs of your hangar, such as insulation, ventilation systems, or overhead doors. While rectilinear roofs offer a flat surface for mounting solar panels or other equipment, gable roofs may be more flexible in accommodating such features. You can choose the best roofing solution for your hangar by weighing these considerations and speaking with experts.

What types of hangar roofing are there
Differentiate between various hangar roofing types:
- single-pitched;
- gable
- gable broken (polygonal);
- arched;
- flat.
Gable or straight pitched roofs are used when building frame structures.
What is better – single-pitched or double-pitched roof, criteria for choosing a design and its differences
The customer chooses the type of roofing when planning a hangar project, taking into consideration the advantages and disadvantages of both structures as well as certain guidelines and recommendations.
Numerous factors influence the type of roof that is selected for the hangar.
- intended purpose;
- complexity of installation;
- appearance;
- reliability;
- climatic conditions of a particular region (especially the amount of precipitation);
- type and strength of the foundation;
- the need for a mansard;
- Material intensity (which determines the cost).
The primary distinction between gable and single-pitched structures is the slope’s characteristics. While the second roof has two opposite slopes, the first variant has a slope in one direction. Every kind of roof also has a variety of additional design elements.
What is a single-pitched roof
A single-pitched roof is a rectangular, entirely flat structure that is angled in relation to the hangar frame. In order to install it, extra supports must be placed along the building’s central axis; if the width is large, supports must be placed in multiple rows. Large equipment cannot be parked in hangars with a single-pitched roof for this reason.
Areas of application
Single-pitched hangars are in the inexpensive category of rapidly constructed structures. This kind of roof restricts the height and width of the object (to a maximum of 10 meters) and consequently limits its use. They are most frequently utilized in contexts that benefit from multi-unit structures, like:
- utility blocks in production;
- small storage facilities;
- garages;
- shopping rows;
- tire repair shops;
- automobile service stations;
- repair shops.
Let’s now examine the kinds of hangars that are best:
Straight-walled hangars are constructed with single-pitched roofs. Compared to analogs, these structures can be built much more quickly and with less money.
Design features
A single-pitched roof has a single-sloped rafter system. The primary feature of this design is the existence of sturdy supports, which hold up the rafters’ two ends. It offers the system’s overall durability and dependability. A single-pitched roof with a slope is supported by walls with varying heights.
Its slope angle is limited to 17 °, as any greater angle will result in a significant rise in wind load. When erecting hangars with a single-pitched roof, consideration is given to the local wind elevation, directing air currents toward the roof’s slope.
Pros and cons
A single slope roofing system offers several benefits.
- relatively light weight, causing a small load on the supporting structures;
- The least consumption of building materials compared to other types of roofs;
- simple and quick installation, reducing the overall construction time;
- ease of operation;
- low cost
- durability.
Single-pitched roofs are ideal for areas with high wind loads because of their resilience to wind gusts.
Single-pitched roofs have the following drawbacks:
- poor thermal insulation due to the low slope;
- lack of possibility to arrange a full-fledged attic room;
- the ability to accumulate snow, which increases the load on the overall structure, resulting in a
- the need for periodic cleaning.
Choosing between hangars with gable and rectilinear roofing depends on several factors including the climate, intended use, and budget. Gable roofing, with its triangular shape, offers better drainage in areas with heavy rainfall or snowfall. It also provides more vertical space inside, ideal for storing tall equipment or machinery. On the other hand, rectilinear roofing, with its flat design, is often more cost-effective and easier to construct. It works well in moderate climates and allows for easier installation of solar panels or HVAC systems on the roof. Ultimately, the choice depends on your specific needs and priorities, whether it"s maximizing interior space, minimizing construction costs, or optimizing energy efficiency.
Gable
A traditional example of a rectangular building is a hangar with a gable roof. The idea behind this roof construction is that there are two slopes that slope in the direction of the outer walls. Every pair of rafters that are resting on one another is positioned independently and joined by a purlin. The roof features rectangular walls at its ends. Gable-roofed structures can have one story or two stories.
Areas of application
Gable-roofed hangars are very popular and have a wide range of uses due to their adaptability. Production facilities, commercial pavilions, warehouses, workshops, aviation hangars, administrative buildings, and agricultural facilities are the most common uses for them.
For what types of hangars are preferred
When building wide hangars without internal support posts, the gable roof is put in place (up to 10 m).
The following kinds of hangar structures use this type of roof:
- rectilinear;
- hipped.
Design features
Most of the time, the slope’s angle on both sides of the roof is the same and falls between 15 and 27 degrees. Gable roofs effectively withstand strong winds and don’t collect a lot of snow. Because of their simplicity, these structures can be quickly fabricated and installed, making them mobile.
Advantages and disadvantages
Benefits of gable roofing include:
- quick removal of precipitation;
- good thermal insulation values;
- Possibility of arranging an attic;
- Even distribution of load on the load-bearing elements;
- ease of repair and maintenance;
- high degree of reliability.
The following can be linked to these structures’ drawbacks:
- small area of attic space;
- impossibility of installation on hangars with a large area;
- the presence of two gables, which can accumulate moisture in the attic space.
Gables will need to be treated with moisture-resistant compounds and insulated to lessen their susceptibility. There are extra expenses involved with all of this.
Which is cheaper
A single-pitched roof is less expensive to install than a gable roof if it does not require the use of pricey insulation materials.
Let’s now examine which option—a single slope or a double slope—is better and why. The majority of builders believe that a gable roof is the best option. There are various reasons behind this decision:
- reliability;
- ease of maintenance;
- practicality;
- good thermal and waterproofing.
Gable buildings are essential in northern areas with a lot of precipitation.
What should be taken into account when choosing
When deciding between the two styles of hangar roofs, it’s crucial to take a few things into account:
- allocated budget;
- the purpose of the construction;
- performance properties;
- weather conditions of a particular region;
- decorative qualities.
| Gable Roof Hangars | Rectilinear Roof Hangars |
| Gable roofs have two sloping sides that meet at a ridge, forming a triangular shape. | Rectilinear roofs have a flat or gently sloping roof surface with no peaks or ridges. |
| Provide more space for storage or equipment near the walls due to the sloping design. | Offer uniform ceiling height throughout the structure, allowing for flexible use of space. |
| Can be more visually appealing and traditional in appearance. | May be more cost-effective and easier to construct. |
| Suitable for areas with heavy snowfall, as the steep slope helps snow slide off. | Preferred for larger hangars or industrial buildings where maximizing interior space is important. |
| Considerations: Choose gable roofs if aesthetics are important, or if snow buildup is a concern. | Consider rectilinear roofs for cost-efficiency and maximizing interior space usage. |
It all comes down to comprehending the primary distinctions between rectilinear and gable roofing for your hangar. The triangular shape of gable roofs, which is created by two sloping sides meeting at a ridge, gives them additional room for equipment or storage. Conversely, rectilinear roofs are easier to build, with just one slope needed for effective water drainage. Because each has benefits and drawbacks, choosing the right kind will rely on your own requirements and tastes.
The intricacy of construction is one key distinction between rectilinear and gable roofing. Because gable roofs need additional support structures and have a triangular shape, they usually require more materials and labor. Longer installation times and greater initial costs may result from this complexity. On the other hand, rectilinear roofs are more economical for people on a tight budget or with time constraints because they are easier to construct and require fewer materials.
The local climate and weather should also be taken into account. Because of their steep slopes, which make it easy for snow to slide off, gable roofs are renowned for their strength and capacity to withstand heavy snow loads. They are therefore the perfect option for areas with severe winters. However, in regions where there is a lot of snowfall, rectilinear roofs might not be as useful because the snow can build up on the single slope and, if it is not adequately reinforced, could cause structural problems.
The choice between rectilinear and gable roofing ultimately boils down to weighing considerations like cost, construction complexity, and suitability for your particular needs and climate. A gable roof might be the best option if you value having plenty of storage space and resilience in inclement weather. But if simplicity and affordability are your top priorities, a rectilinear roof might be a better choice. Regardless of the option you select, make sure your hangar is installed and maintained properly to extend its lifespan and maximize its usability.
