What Roofers Do
Local Roofers-Roofers in Pasadena Ca-Roofers in Arcadia.
Roofers replace, repair, and install the roofs of buildings using a variety of materials, including shingles, bitumen, and metal.
Roofer typically do the following:
Inspect problem roofs to determine the best way to repair them
Measure roofs to calculate the quantities of materials needed
Replace damaged or rotting joists or plywood
Install vapor barriers or layers of insulation
Install shingles, asphalt, metal, or other materials to make the roof weatherproof
Align roofing materials with edges of the roof
Cut roofing materials to fit around walls or vents
Cover exposed nail or screw heads with roofing cement or caulk to prevent leakage
Properly installed roofs keep water from leaking into buildings and damaging the interior, equipment, or furnishings. There are two basic types of roofs: low-slope and steep-slope. Solar and vegetative features are sometimes incorporated into both low- and steep-slope roofs. Roofers may specialize in the installation and replacement of one or more of these roof systems.
Low-slope. Low-slope roofs rise less than 3 inches per horizontal foot and are installed in layers. Low-slope roofs make up nearly three-quarters of all roofs, as most commercial, industrial, and apartment buildings use this type.
Many of today’s low-slope roofs are covered with a single-ply membrane of waterproof rubber or thermoplastic compound. Most previously installed low-slope roofs, however, use several layers of roofing materials or felt membranes stuck together with hot bitumen (a tar-like substance).
Steep-slope. Steep-slope roofs rise more than 3 inches per horizontal foot and most commonly use asphalt shingles, which often cost less than other coverings. Steep-slope roofs make up most of the remaining roofs, as most single-family homes use this type.
Although roofers most commonly install asphalt shingles, some also lay tile, solar shingles, metal shingles, or shakes (rough wooden shingles) on steep-slope roofs. Traditional roofing systems may incorporate plants and landscape materials, and these features are becoming more common. A vegetative roof is typically a waterproof low-slope roof, covered by a root barrier. Soil, plants, and landscaping materials are then placed on the roof.
Solar features are increasingly popular on roofs. These systems include solar reflective, which prevents the absorption of energy; solar thermal, which absorbs energy to heat water; and solar photovoltaic, which converts sunlight into electricity. Roofers install some photovoltaic products such as solar shingles and solar tiles, but solar photovoltaic (PV) installers typically install PV panels. Plumbers and heating, air conditioning, and refrigeration mechanics also may install solar thermal systems.
Local Roofers-Roofers in Pasadena Ca-Roofers in Arcadia a roofer or roof mechanic is a construction worker who specializes in roof construction. Roofer concentrate on the application of materials that waterproof and/or weatherproof buildings, designed material—as a substrate for the roofing materials to be installed on, the rafters, beams, and trusses are the frame or skeleton for the roof to be built upon. Roofers must be able to work, have good motor skills and possess general carpentry skills.
Throughout the world
In Australia this type of carpenter is called a roof carpenter and the term roofer refers to someone who installs the roof cladding (tiles, tin, etc.)
n the United States, the most common roofing material is asphalt shingles. In the past, 3-tab shingles were used; nowadays, "architectural" or "dimensional" shingles are becoming very popular.
Depending on the region, other commonly applied roofing materials installed by roofers include concrete tiles, clay tiles, natural or synthetic slate, single-ply (Primarily EPDM or Rubber, PVC, or TPO), rubber shingles (made from recycled tires), glass, metal panels or shingles, wood shakes or shingles, liquid-applied, hot asphalt/rubber, foam, thatch, solar tiles, and specialty roofs like Duro-Last. "Living roof" systems, or rooftop landscapes, have become increasingly common in recent years in both residential and commercial applications.
In the United States, regulation of the roofing trade is left up to individual states. In California, for example, the California Contractors State License Board licenses and monitors roofing contractors. Unlicensed contracting of projects worth over a set threshold may result in stiff fines or even time in prison
The United Kingdom has no legislation in place that requires a roofer to have a license to trade, although some do belong to recognized trade organizations.
Types of roofers
There are 4 main types of roofers: shinglers, who primarily install shingles, shakes, tiles, and other nail-on products on roofs with 5:12 pitches or above; metal roofers, who focus on metal panels; single-ply or "flat" roofers, who focus on roofs such as single-ply or foam roofs; and "hot" roofers, who work using tar-based products. It is not uncommon, however, for companies to have their roofers to multiple styles of roofing, and certain manufactures will only allow specifically selected installers, thus making these 4 types limiting
