About the Catslide roof

The catslide roof is a variant of both the regular gable roof and the asymmetrical gable roof.

It’s effectively a regular gable roof extended on one side to the extent that there’s one less story at the rear than at the front.

The catslide roof is the traditional roof type you’ll find on New England ‘saltbox houses’, which have two stories at the front and one at the rear.

Extending the roof plane from main-eave height down to ground-floor eave height, as is the case with the catslide roof, has the effect of providing greater area under the roof without increasing the ridge height.

Synonyms catslide roof

You’ll hear different terms used for the catslide roof, including the saltbox roof. And maybe asymmetrical gable roof.
