What is a Skillion Roof?

Skillion roofs have a single sloped flat surface. They are popular for minimal and contemporary-style homes.

A skillion roof is inexpensive and easy to build. While you’ll often see these roofs on minimal architecture, they’re also a top pick for outbuildings. They provide optimal water drainage but aren’t ideal for areas with high winds.

If you’re considering a skillion roof for your home, garage, or shed, here’s what you should know.

What is a Skillion Roof?

A skillion roof features one flat, sloped surface. Other names for this style include a lean-to and mono-pitched roof.

Designers use skillion roofs on minimal-style homes. They’re also popular for home additions, sheds, and garages due to their easy construction and high pitch. 

Are Skillion Roofs Strong?

Skillion roofs are structurally strong. Their steepness provides optimal water drainage, and skillion roofs with a high-pitch work well for snowy climates.

These roofs are not a good choice for areas that experience frequent high winds. Since they only have one slope, they’re more likely to sustain wind damage than a hip or gable roof, for example.

Pros and Cons of a Skillion Roof

Skillion roofs are ideal for any homeowner looking for a contemporary, cost-efficient, or easy-to-build solution. But along with their strong set of pros are a couple of disadvantages. 

Here’s a look at the pros and cons of a skillion roof.


Pros of a skillion roof:

  • Easy to build – A skillion roof features one flat, sloped surface, making this roof one of the easiest to build.
  • Affordable – Fewer intricacies and simple building plans result in a less expensive roof.
  • Modern aesthetic – Skillion roofs have a modern aesthetic, ideal for contemporary and minimal style homes.
  • Good choice for home additions – A skillion roof is ideal for home additions or extensions.
  • Optimal water drainage – A skillion roof has excellent water drainage due to the steep slope.
  • Ideal for Snow – Roofs with a high pitch are ideal for snowy climates since the steep angle allows melting snow to run off.

Cons of a skillion roof:

  • Not ideal for high winds – Due to the steep pitch and singular surface, skillion roofs are prone to wind damage and unsuitable for hurricane-prone areas.
  • Less attic space – The pitch majorly reduces the amount of attic space in a home which can be a con if you need extra storage space.
