A roofer, roof
mechanic, or roofing contractor is a construction worker who specializes in roof construction. Roofers replace, repair, and install the roofs of buildings, using a variety of materials, including shingles, bitumen, and metal. Roofing work can be physically demanding because it involves heavy lifting, as well as climbing, bending, and kneeling,
often in extreme weather conditions.[1]
Throughout the world[edit]

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.).
In the United States and Canada, they're often referred
to as roofing contractors or roofing professionals. The most common roofing material in the United States is asphalt shingles.
In the past, 3-tab shingles were used; nowadays, "architectural" or "dimensional" shingles are becoming
very popular.[2]
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 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, and solar tiles. "Living roof" systems, or rooftop landscapes, have become increasingly
common in recent years in both residential and commercial applications.[3][4]
In the United States, regulation of the roofing trade is left
up to individual states. Some states leave roofing regulation up to county-level and municipal-level jurisdictions.[5] In California, for example, the California Contractors State License Board licenses and monitors
roofing contractors.[6] Unlicensed contracting of projects worth over a set threshold may result in stiff fines or even time
in prison.[7] In Oklahoma roofers are required to meet insurance and roofing license guidelines. Roofers are also
required to show their license number on their marketing material.
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.[citation needed]
Types of roofers[edit]
There are four 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 service multiple styles and types of roofing; and certain manufactures will allow only pre-approved
installers, thus making these four roofer types limiting. As per the application areas, roofing contractors can be categorized
as Industrial or commercial roofers, Factory Shed roofers, Residential Roofers, Commercial roofers. Based on the types of
the materials, roofing can be classified as terrace roofing, metal roofing, polycarbonate roofing, steel roofing, PVC roofing,
skylight roofing. Pre-engineered companies installs roofing.
