DESCRIPTION OF ESSENTIAL FUNCTIONS: This specialized carpenter roofer installs roofing materials such
as composition, metal or fiber reinforced shingles, roll roofing (sheets), wood shakes and shingles, clay or
similar tile, hot and cold tar and gravel/rock material on roofs according to customer specifications (plans),
local buildings codes and manufacturers directions. The roofer may work for a business that specializes in
installing roofs on new structures or one that specializes on replacement roofs. A roofer may also work for
a business that does a combination of new and replacement roofs.
Roofing paper installation – roofing paper is installed the same way regardless of the type of roof
material being installed or new versus a re-roof project. The process consists of rolling out the roofing
paper and cutting it to length using a utility knife. The roofing paper is then tacked into place using a
hand held stapler.
Composition shingle installation – When installing a composition shingle roof the roofer will start at the
bottom of the roof will lay down a course of shingles that are inverted. This will serve as a base course.
Next a starter course is nailed into place directly over the base course. Roof shingles may be hand nailed
or nailed into place with a pneumatic nail gun. When a shingle needs to be cut it is done using a utility or
roofing knife. A roofing hatchet (hammer) is used to hand nails shingles. Each course of roofing shingles
is spaced using the gauge on the roofing hatchet or a chalk line and the joints are staggered to prevent
water from seeping into the structure at the joints.
Composition roll material installation – When installing this type of roofing material the roofer will
start at the bottom of the roof and roll it out to cover the length of the roof. The material is then nailed
into place and nail heads covered with roofing tar. Each subsequent section is overlapped and nailed into
place either by hammer or pneumatic nail gun. A utility or roofing knife is used to cut the roofing
material. Chalk lines are used to keep the material square and straight.
Wood shake or shingle installation – When installing this type of roofing material the roofer uses a
roofing hatchet to cut and trim the material. A chop saw can be used to make more precise cuts. Like
composition and roll roofing wooden shakes and shingles are fastened with nails and spaced with the
guide on the roofing hatchet or chalk lines.
Tile Installation - When installing this type of roofing material, the roofer will insert roofing wire into a
pilot hole in the tile and then nail/staple the wire to the roof structure (sheathing). A tile saw is used to
cut the shingles as needed. Tile ridge and valley cap is installed with nails and/or an adhesive/mortar.
Hot and cold tar roof systems – When installing this type of roofing material the roofer will apply the
hot or cold tar to the roof with a mop. As this is being done another employee will roll out a sheet of
roofing material (bay sheet). The bay sheet is then lifted over the tar and set into position on top of the
tar and pressed into the tar. Once the roof has the first layer completely applied a second and third layer
ply layer is installed is using the same process. The final step involves application of the cap sheet. This
is rolled out in sections and once the tar is in place it is flipped into position and then pressed into the tar
usually by walking on the roof surface. On hot tar applications the material is heated in specialized pot
where it is melted and then pumped to the roof top where it is applied with a mop. Cold tar works in the
same way but does not require melting and is typically in five gallon buckets.
Flashing installation - metal flashing is installed on skylights, chimney, and wall joints to deflect water
from the joint area. Metal flashing can also be used on valleys where roof lines intersect and for sealing
around pipes. Metal flashing is installed just like just like roofing shingles with nails and hammer or air
nailer and cut with tin snips.
