What Is a Gable Roof?

A gable roof consists of two different roof sections placed in a way that creates a peak. Typically, they are produced by adding rafters, trusses, and purlins before installing the roofing materials. The angle will vary greatly, depending on your customer’s needs. Some will want very high gabled roofs that create an almost cathedral-style look.

However, others will want a shallow roof that doesn’t stand out excessively from their neighbors. Larger houses may even use multiple gables to create a roof. Remember the book and movie “The House of Seven Gables”? It’s not unusual for larger houses to use many gables to create a variety of different looks and styles.

There’s a good chance you’ve already seen a significant number of gable roofs in your hometown. You can see them in areas with heavy rain and snow, as well as in relatively dry areas. Their installation ease is the primary cause of their popularity. As they consist of just a few parts that don’t take much work to put together, they are easier to install and less expensive than many other roof types.

Pros and Cons of a Gable Roof

Advantages of Gable Roof

There are many reasons that gable roofs remain so popular. We’ve already talked about their installation ease. However, they are also very versatile for a variety of homes. For example, a tall gable roof can keep water from pooling during rainy seasons. However, a shallow gable roof can prevent snow from falling off too quickly and creating a dangerous situation.

Gable roofs are also a beautiful addition to a home that increases its air circulation and makes them more distinctive. Even though gable roofs are among the most popular roof types available, they can be adapted in many different ways. These adaptations make it very easy to create unique styles that please your customers and give them the roofing experience they want.

Other advantages to consider are the following ones:

  • Weather-resistant abilities.
  • Cost-effective nature.
  • Classy style that will always look great.

These advantages are a major part of what make these types of roofs so popular. However, there are disadvantages that you need to understand before installing one. Each must be discussed with your customer to give them an accurate understanding of their roofing investment.

Disadvantages of a Gable Roof

When you’re installing these types of roofs for your customers, it is important to understand the few disadvantages they offer. Just a few reasons that gable can be a problem include the following:

  • Poor ventilation – Typically, gable requires extra vents to avoid this problem.
  • Limited choice of windows – You can only choose from roof and gable windows when using this type of roof.
  • Decreased living space – When installing low-angle gables, you decrease the available living area for yourself or your customers.

While there are ways to get around these problems, they do need to be discussed with your customers before installing this type of roof. For example, you could increase the angle height to increase the living area available in the home. You could also find low-cost vents that provide excellent ventilation for this roof type without adding too much to its cost.

What to Expect from a Gable Roof: Guidelines/Standards/Practices/etc.

The biggest thing you’re going to have to understand when installing a gable roof is proper framing. It requires the use of the Pythagorean Theorem. This calculation (a2+ b2=c2) is used to calculate the length of the longest sides in the two right triangles that make up your gable roof. It’s an easy-to-understand theorem that gives you an immediate estimate of your roof size.

You also need to choose the best kinds of roofing material for the climate. Try to avoid rubber roofing in warm climates, as these will increase the interior temperature of a home. Clay tiles are a good choice in this situation. They not only block heat from entering the home, but they also promote smoother water and snow flow off of the gable roof and avoid severe damage.

It is also important to discuss installation permits with the local authorities to ensure that you meet all eco standards. Talk to your suppliers about the most ecologically-safe gable roof building materials on the market. We suggest clay, again, as it doesn’t have many nasty chemicals that can cause serious runoffs and ecological damage.

Also, make sure that all your materials have a warranty. In this way, you can avoid having to pay extra if you make a mistake. For example, if you choose materials that don’t work well for your customer’s roof, a good warranty from your supplier will ensure that they will replace the materials for you without asking for too much money.

To Conclude with

As you can see, gable roofs have many advantages that make them an attractive item to install. However, they also have disadvantages that your customers need to understand before you put one on them home. That said, these roof types are popular and aren’t likely to go away anytime soon.

So if you are installing a gable roof on someone’s house, make sure to talk to them about it before starting. Discuss the benefits and drawbacks in an honest way and explain just how much a good gable roof can help them out. In this way, they know what to expect.
