Gable Roofs

Perhaps less artful
than a hipped roof, but certainly more practical, a gabled roof has
two slopes that come together at the top; each end looks like the
letter A. Gable roof consists of two roof surfaces, called roof
fields, which are usually rectangular and are the same size and pitch
angle. The gable roof is the most popular choice of roofing and
because its trusses are less complex, it is the cheapest and simplest
type of roof to construct.

Gable roofs designers
recommend the 25-45° pitch angle of the roofs as it represents
the best angle for the effluxion of the rain water. The line in which
both roof surfaces meet is called a ridge or ridge line. The gable
roof ridge is of the same length as the longer side of both roof
fields. The end gables allow for windows or vent openings for extra
ventilation.

The roof pitch
determines the space available in the attic. A low pitched roof
reduces the headroom in the attic. Conversely, the higher the pitch
of the gable, the more headroom. Therefore, a higher pitch provides a
very workable living space in your attic. Dormers are commonly added
to roofs to provide additional windows to living space constructed in
what was traditionally the attic.

In some older styled
homes that occupied smaller parcels of land, often found in cities,
the attic was outfitted for the servants of the home because it was
not well insulated against the cold or the heat and wasn’t as
comfortable as the lower floors of a multi-storied house.

Homes with gabled roofs
are more likely to suffer damage, such as collapse of the end wall
from high winds in cases when they are not braced properly during
construction. They can be the worst type of roof to have in hurricane
regions because a gable end can catch wind like a sail.

One of the most common and certainly most popular roofing styles available, gable roofs are easier to install and less expensive than other types of roofs. Gable roofs may not be able to withstand hurricane winds like hip roofs, but with the proper maintenance they can last for years to come. Here is some more information.

Costs

The cost of installing a gable roof depends on the type and quality of the materials used, as well as the cost of labor. Get in touch with a local roofer for price quotes and to go over your options.

Pros

Gable roofs are the cheapest and simplest type of roof to construct.

They are more practical than any type of hip roof.

The shape of a gable roof is better for water run-off, which in turn prevents the build-up of mold and mildew.

Cons

Gable roofs are far more susceptible to damage from high winds than other roof styles.

They are not as aesthetically pleasing as hip roofs.

Gable roofs tend to require more maintenance than other types of roofs.

Durability

If a gable roof is built with quality materials and properly maintained, it can be a durable roof for your home. However, gable roofs can be easily damaged with high winds, and are not recommended in areas prone to severe hurricanes.

Maintenance

Gable roofs require more maintenance than other roof styles, and must first be completely weatherproofed. It’s suggested that roof vents and possibly vent fans be installed to prevent any moisture damage. Also, be prepared to repaint your gable roof from time to time, as this style has a broader face than others.
