Job Description:
Roofers install and remove roofs on buildings and other structures to make them waterproof and weatherproof.  They may also waterproof or damp-proof walls and other building surfaces. 

Roofers may also use materials such as: composition shingles, tile, slate, EPDM (ethylene, propylene, diene, terpolymer) membrane, 
PVC (polyvinyl chloride systems), butyl rubber, PIB (polyisobutylene), CPE (chlorosulfonated polyethylene), ECB (ethylene-copolymerbitumen and anthracite dusts), modified bitumens. Roofers prepared some roofing materials by cutting roofing paper, shingles, or sheet to size and by punching, perforating, or shaping shingles, sheets, slate, or flashing.  They align roofing material with the edge of the roof and overlap successive layers, fastening them with asphalt cement or nails.

To install composition roofs, the Roofer places overlapping strips of asphalt or impregnated felt on the roof, and applies coats of coal tar pitch or asphalt, to the surface.

To waterproof, the Roofer removes rough projections and roughs glazed surfaces, using hammer and chisel and applies waterproofing solution.

Tools used by Roofers include hammers, roofing knives, pincers, and caulking guns.  Modern equipment has lessened the physical exertion formerly required.

Working Conditions: 
Work is done outdoors in all kinds of weather except when conditions are very severe.  The Roofer does a great deal of climbing, kneeling, standing, and walking in high places.  They must be alert to the danger of falling.

Reap the rewards: 
Roofers, who complete apprenticeship, earn top wages as full journeyman. Benefits include Health insurance, vacation, pension, and annuity funds. As an apprentice you will be able to earn a good living while you learn the skills needed to become a fully qualified journeyman. Upon completion of the apprenticeship program you will have the skills to ensure a lifelong career, and the ability to work in locations anywhere in the United States.

Interest and Temperament: 
A Roofer should have no fear of height, a good sense of balance, and a better-than-average sense of safety for himself and his co-workers.  They should enjoy working with their hands and accept working outdoors, sometimes under unpleasant working conditions.
