What is a Sawtooth Roof?

The sawtooth roof has been seeing a revival lately. Once it was the standard roof for a factory or mill, but because of the ample amount of daylight they let in, the sawtooth roof a popular choice for eco-conscious homebuilders.

The profile of this roof looks like a row of tents leaning against each other, but actually they are built according to strict measurements that will allow in the most daylight.


The main reason people want the sawtooth roof style is it lets in lots and lots of sunshine. Before electricity, this was essential for factory production because workers needed a lot of light to be able to see, especially when creating textiles.
Now, more sunlight means less energy consumption for heating and lighting, making homes and businesses more environmentally friendly and a little easier on the pocketbook.
The sawtooth gives you lovely high ceilings too. An open concept home would go well with this type of roof.


The sawtooth design is very thoughtful: the angles of the sun need to be measured and planned perfectly. But extra thought and design can mean more costs. Sawtooth roofs also require a lot of materials. Lastly, because of the windows and various angles, sawtooths are more likely to leak.

Roofing Materials to Use

If you’re building a sawtooth roof, the best materials to use are wood, metal, or concrete. These traditional materials have been tried and tested, so they’re a safe choice.
Since a large part of the roof is glass, some builders reinforce the glass with a layer of wire mesh between panes of glass for extra security and strength.

Roofing Materials Not to Use

Asphalt shingles are probably the worst choice for the sawtooth roof. There are many valleys and ridges, and if the design is combined with other roof styles, the joints between them can be weak and prone to more wear and tear. Asphalt shingles just aren’t as durable as metal roofing, slate roofing, or newer plastic shingles.
