Gable roofs are particularly popular in the Northeast region as it’s practical for the kind of climatic conditions in that region.
The gable roof design includes two or more steep stones, making the surface resistant to rainwater and snow by allowing it to shed down instead of accumulating. This style is less prone to roof leakage and water damage over the period you’d need to spend less on its maintenance.

What is a Gable Roof
A Gable roof is made up of two sides that meet at a sloped angle to form a ridge in the centre, making a triangle shaped roof. The angle of the ridge can be different as per the house. The ridge can either be parallel or perpendicular to the front of the house, it depends on the aesthetics you’re aiming for.
The two panels form a tell-tale triangular shape under the ridge on either side of the home. These triangular shapes are under the ridge, also known as gable ends.
Gable Roof Types
Standard gable consists of two panels which rise at a slanted slope to make a ridge in the middle; it can either be steep or shallow. This slanted roof is the best option for shedding rainwater or accumulated snow.
Standard gable roofs are usually parallel to the door with the shingled part facing front and the backside of a house. In contrast, a front gable is perpendicular to the door with the shingled planes facing sideways of the house.
Box gable resembles the standard one, only it is an upgraded version of the classic gable roof. Its design eliminates excess precipitation falling directly at the home’s foundation. The box gable roof has extended gable ends, making it look like an overhang, making water or snowfall a bit of distance from the walls.
When two gable roofs intersect at the right angle, resembling the alphabet T or L from the above known as cross gables, the two ridges meet at the highest point of the roof perpendicular to each other.
In a Dutch gable roof, hip and gable roofs are present, making it unique. It looks like the gable roof is placed upon a hip roof. This design gives the loft extra space. People prefer Dutch gable due to its uniquely appealing, irregular shape yet aesthetically pleasing and for the additional space it provides.
For extra sunlight and space, people usually add a gable with a dormer roof to their standard gable roof. These dormers peep out of the flat roofs, making more interior space. Also, these dormers’ huge windows allow a lot of extra sunlight in. These gabled dormers are also known as dog house dormers.
Homes with saltbox roofs are usually one and a half or two-story buildings. Saltbox gable roofs also resemble standard gable roofs; the only difference is these roofs are not symmetrical and came into existence way before the standard ones. Some of the earliest Northeast settlers built homes with saltbox gable roofs.
The saltbox gable roofs look pretty standard from the front side, whilst the back side extends downward, making the home look as if it is leaning backwards.
Gable overhangs are the extended roof at the front porch or front steps to keep the shedded precipitation away from their steps while heading out of the front door; these overhangs make the snow and water fall onto the sides of the house instead of spilling them at the doorstep.
Also, gable overhangs give a classic touch to the homes.
Gable with Shed Roofs
Adding an extra plank like structure to extend the existing roof makes the shed for the front step or porch. This hybrid style allows people to extend their roof without disturbing the pre-existing structure.
Materials for Gable Roofs
People prefer different kinds of materials based on their budget and aesthetic demands. However, every type of roofing material can be used to construct a gable roof except roller rubber. It doesn’t work very well for this kind of roof due to its flexible properties. These flexible sheets would act as sails while the wind blows across the surface and eventually tear up, forcing you into repairing it.
The joist and rafters are made up of lumber, and then there is a layer of plywood over the lumber frame and other material’s underlayment protecting your home from heat and roof leakage. The very last layer is known as shingles which is used to cover this whole underlayment.
Here are some of the common materials used for gable roofs
Asphalt- Asphalt shingles are the most common material used for slanted roofs because they are weather resistant and reduce the chances of roof leakage on rainy days.
Metal Roofs- Metal roofs are more durable and endure extreme climatic conditions better than the asphalt shingles but they are also expensive and require a little more maintenance in order to last long.
Tile Roofs- Tiles as a roofing material are durable and can easily last for 60-100 years. However, their installation process is a bit of work due to their heavy weight. Tiles are weather resistant and require significantly less maintenance but their estimated cost is much more than an asphalt shingle.
Cedar Shake- Cedar woods are common material for the roof as it prevent leaks around the corners. Though they look attractive, they require a lot of care and maintenance as the cedar sustains damage due to water.
