Gravel shake roof.

Built up roofs or burs also called a tar and gravel roof is a well established and popular style of flat roof that is made up of alternating layers of roofing felt or fiberglass and asphalt that is applied with heat which combine to make a long lasting sturdy roofing system. Cedar wood shakes have been used in america since colonial times having been the primary roofing system installed for hundreds of years. Here alternating layers of roofing felt usually fiberglass and hot applied asphalt are combined to create a long lasting roof system.

Shakes or shake shingles have been used for roofing and siding for centuries. The old tar and gravel roof type has been used on relatively flat roofs for over 50 years but many newer systems and specific material types including modified membrane systems are becoming increasingly available in residential applications. I m trying to ask for a full roof replacement saying that it will almost be impossible to know which of the 296 shakes i replace are the same. A built up roof for example will typically include the built up membrane itself with or without gravel as well as some kind of insulation and cover board which will vary in thickness from roof to roof.

Traditional wood shakes were created by splitting logs wood along the grain.
