Nature of the Queens Roofing Contractors Work
Back to Top
A leaky roof can damage ceilings, walls, and furnishings. To protect buildings and their contents from water damage,
Queens Roofing Contractors repair and install roofs made of tar or asphalt and gravel; rubber or thermoplastic; metal; or shingles made of asphalt, slate, fiberglass, wood, tile, or other material. Repair and reroofingreplacing old roofs on existing buildingsprovide many job opportunities for these
roofers. Roofers also may waterproof foundation walls and floors.
There are two types of roofsflat and pitched (sloped). Most commercial, industrial, and apartment buildings have flat or slightly sloping roofs. Most houses have pitched roofs. Some
Roofing Contractors work on both types; others specialize.
Most flat roofs are covered with several layers of
materials. Roofing Contractors first put a layer of insulation on the roof deck. Over the insulation, they then spread a coat of molten bitumen, a
tar like substance. Next, they install partially overlapping layers of roofing felta fabric saturated in bitumenover the surface.
Roofing Contractors use a mop to spread hot bitumen over the surface and under the next layer. This seals the seams and makes the surface watertight.
Roofing Contractors repeat these steps to build up the desired number of layers, called "plies." The top layer either is glazed to make a smooth finish or has gravel embedded in the hot bitumen to create a rough surface.
An increasing number of flat roofs are covered with a single-ply membrane of waterproof rubber or thermoplastic compounds. Roofers roll these sheets over the roof's insulation and seal the seams. Adhesive, mechanical fasteners, or stone ballasts hold the sheets in place. The building must be of sufficient strength to hold the ballast.
Most residential roofs are covered with shingles. To apply shingles, roofers first lay, cut, and tack 3-foot strips of roofing felt lengthwise over the entire roof. Then, starting from the bottom edge, they staple or nail overlapping rows of shingles to the roof.
Roofers measure and cut the felt and shingles to fit intersecting roof surfaces and to fit around vent pipes and chimneys. Wherever two roof surfaces intersect, or shingles reach a vent pipe or chimney, roofers cement or nail flashing-strips of metal or shingle over the joints to make them watertight. Finally, roofers cover exposed
nail heads with roofing cement or caulking to prevent water leakage.
Some roofers also waterproof and damp proof masonry and concrete walls and floors. To prepare surfaces for waterproofing, they hammer and chisel away rough spots, or remove them with a rubbing brick, before applying a coat of liquid waterproofing compound. They also may paint or spray surfaces with a waterproofing material, or attach waterproofing membrane to surfaces. When
damp proofing, they usually spray a bitumen-based coating on interior or exterior surfaces.
Roofing work is strenuous. It involves heavy lifting, as well as climbing, bending, and kneeling. Roofers work outdoors in all types of weather, particularly when making repairs. These
roofers risk slips or falls from scaffolds, ladders, or roofs, or burns from hot bitumen. In addition, roofs become extremely hot during the summer.
Roofing Contractors held about 158,000 jobs in 2000. Almost all wage and salary roofers worked for roofing contractors. About 1 out of every 4 roofers was self-employed. Many self-employed roofers specialized in residential work.
Roofing Contractors Training, Other Qualifications, and Advancement
Back to Top
Most Queens Roofing Contractors acquire their skills informally by working as helpers for experienced roofers. They start by carrying equipment and material, and erecting scaffolds and hoists. Within 2 or 3 months, trainees are taught to measure, cut, and fit roofing materials and, later, to lay asphalt or fiberglass shingles. Because some roofing materials are used infrequently, it can take several years to get experience working on all the various types of roofing applications.
Some roofers train through 3-year apprenticeship programs administered by local union-management committees representing roofing contractors and locals of the United Union of Roofers,
Waterproofers, and Allied Workers. The apprenticeship program generally consists of a minimum of 2,000 hours of on-the-job training annually, plus 144 hours of classroom instruction a year in subjects such as tools and their use, arithmetic, and safety. On-the-job training for apprentices is similar to that for helpers, except that the apprenticeship program is more structured. Apprentices also learn to
damp proof and waterproof walls.
Good physical condition and good balance are essential for roofers. A high school education, or its equivalent, is helpful, as are courses in mechanical drawing and basic mathematics. Most apprentices are at least 18 years old.
Roofers may advance to supervisor or estimator for a roofing contractor, or become contractors themselves.
Jobs for Queens Roofing Contractors should be plentiful through the year 2010, primarily because of the need to replace workers who transfer to other occupations or leave the labor force. Turnover is highroofing work is hot, strenuous, and dirty, and a significant number of
roofers treat roofing as a temporary job until something better comes along. Some
Queens Roofing Contractors leave the occupation to go into other construction trades.
Employment of Queens Roofing Contractors is expected to grow about as fast as the average for all occupations through the year 2010. Roofs deteriorate faster than most other parts of buildings and periodically need to be repaired or replaced. About three-fourths of roofing work is repair and replacement, a higher proportion than in most other construction work. As a result, demand for roofers is less susceptible to downturns in the economy than that for other construction trades. In addition to repair and reroofing work on the growing stock of buildings, new construction of industrial, commercial, and residential buildings will add to the demand for roofers. Jobs should be easiest to find during spring and summer, when most roofing is done.
In 2000, median hourly earnings of expert roofers were $13.95. The middle 50 percent earned between $10.72 and $18.86. The lowest 10 percent earned less than $8.68, and the highest 10 percent earned more than $24.47. The median hourly earnings in 2000 of roofers in the roofing, siding, and sheet metal work industry were $14.00.
Some roofers are members of the United Union of Roofers, Waterproofers, and Allied
Apprentices usually start at about 40 percent of the rate paid to experienced
Queens Roofing Contractors and receive periodic raises as they acquire the skills of the trade. Earnings for roofers are reduced on occasion because poor weather often limits the time they can work.
Queens Roofing Contractors use shingles, bitumen and gravel, single-ply plastic or rubber sheets, or other materials to waterproof building surfaces.
Roofers in other occupations who cover surfaces with special materials for protection and decoration include
carpet, floor, and tile installers and finishers;
cement masons, concrete finishers, segmental pavers, and terrazzo workers;
drywall installers, ceiling tile installers, and tapers; and
plasterers and stucco masons.
