Tile: The most aesthetically appealing
and durable roofing material is tile. Properly installed, these roofs will last
a lifetime. Although older roofs may use clay tiles, concrete is the more
common material these days. In addition to the traditional round red-clay tiles
(sometimes called Mission, Spanish, or Barrel) many builders offer a flat
concrete tile. These flat tiles often give the impression of a slate
Recently light-weight cement tiles have been developed that are
suitable for re-roofing projects. In this case, all previous roof coverings
must be removed.
Clay and cement are environmentally friendly consisting
of natural materials (clay or sand and cement). In addition, most tile roofs
will last from 50 to 100 years. During that time, shake and asphalt roofing
should be replaced four or five times. Tile roofing is also more energy
efficient, reflecting solar rays and creating a better R-factor.
will become brittle over time and the homeowner should avoid walking on the
roof. If the home has a roof-mounted air conditioning unit, the access area of
roofing should be composition shingle.
Composition Shingle: A composition shingle is made from a combination of various
materials, usually felt or fiberglass impregnated with asphalt and coated on
the surface with mineral granules. The shingles are applied over a base of wood
sheathing and building paper. There are many grades of shingle and these are
usually evaluated in terms of weight, surface texture, and their life
expectancy. In other words, a 25-50 year laminated shingle would be superior
to the standard 15-20 year product.
In Las Vegas you can expect to
replace composition shingles within 20 years.
Luxury homes built in the 60's and 70's often sported cedar-shake roofs. Most
of these roofs have reached the end of their useful life and show visible signs
of warping and cracking. Rather than replacing the shakes, it is recommended
that you re-roof with tile.
Tar and Gravel: Although
seldom found in residential homes of today, many older Las Vegas homes were
roofed with tar and gravel. This roofing was suitable for flat or moderately
pitched roofs. Many re-roofing jobs for low sloping roofs use a Modified
Bitumen Roofing - (TorchDown) system which may last from 10-20 years.
