Roof Extensions Design
Roof extensions should match the roof type, angle and pitch of the original property. Pitched roof materials should match the original, and flat or mansard roofs on traditional buildings are seldom acceptable unless not visible from public views.
An extension or alteration which copies the roof type and angle of pitch of the original residential property will be more successful than those proposals that introduce a completely different type of roof. The roofing material of any pitched roof extension should seek to match that of the original. Flat or mansard roofed extensions to traditional buildings are seldom harmonious. However, they may be acceptable where they are not open to public views.
