Page "Roof" Paragraph 52

There are regional building styles which contradict this trend, the stone roofs of the Alpine chalets being usually of gentler incline.

These buildings tend to accumulate a large amount of snow on them, which is seen as a factor in their insulation.

The pitch of the roof is in part determined by the roofing material available, a pitch of 3 / 12 or greater slope generally being covered with asphalt shingles, wood shake, corrugated steel, slate or tile.
