Clayton Restoration - Commercial Roofing

Clayton Restoration has been repairing and installing mansard roofs on St. Louis buildings for more than 30 years.

The Mansard roof is named for Francois Mansart, a 17th century French architect and the “Father of French Classical Architecture.”

Did You Know: Roof pitch and roof span are not the same thing.

Pitch is the measurement of the rise of the roof to the span of the roof and is expressed as a fraction (2/12).

Slope is the measurement of the rise of the roof to the run of the roof and is expressed as inches per foot in a ratio format (4:24).

Also called a “French roof,” this four-sided roof has a double slope on each side. The slopes meet to form a low-pitch. Its sides can be flat or curved. The top of a mansard roof is typically broad and flat, and its lower pitch is available in three silhouettes:

  1. Convex (outwardly curved, in an “S” or bell shape)
  2. Concave (inwardly curved or flared)
  3. Steeply angled

The pitch of a Mansard Roof is typically about 21:12. Because of its very steep slope, a Mansard roof usually requires additional fastening methods reserved specifically for steep-sloped roofing materials.

You may hear contractors refer to any roof with a very steep slope as a Mansard roof, but the term “Mansard” simply describes a particular type of architecture.

Commercial Mansard roofs require one of several types of materials made specifically for steep-sloped roofs. The most common of these are:

  • Asphalt shingles
  • Wood shake
  • Wood shingle
  • Clay tile
  • Concrete tile
  • Metal shingles
  • Metal panel
