There are many types of roofing materials that can be used on your cabin. To some extent,
choice of materials will depend upon whether
roof is pitched or flat. The table on page 120 indicates whether you should use a roll or shingle type of roofing material.
Asphalt shingles require a roof pitch of at least 4 inches to each lineal horizontal foot. When
pitch is this low, most manufacturers of roofing materials recommend that roofing felt or asphalt-saturated building paper be laid under
shingle roof. If your roof has any valleys, I'd suggest that you start your work by laying heavy roofing felt down
center of
valley.
One layer of felt, 18 inches wide, should be laid face down. Then a second layer, full width, should be laid face up. After this is nailed down, you can start laying
under roofing felt or paper. Manufacturers' recommendations vary, but you'll be pretty safe if
edges overlap about 2 inches horizontally.
Start with
lowest part of your roof. Let
edges of
paper overlap
end of
roof by 2 or 3 inches. This overlap should be cut later, a little under
first shingle course. The next layer of paper will overlap
lower one by 2 inches. Continue this process to
peak of
roof.
When both sides of
roof are finished, lay one width of paper over
ridge pole. Short wide-head roofing nails should be used with this paper. When
paper has been put down, use a carpenter's chalk line, which is impregnated with chalk, and snap
guidelines for
shingles. If your shingle exposure is 4 inches, you will want to snap chalk lines with this spacing all
way from
first course to
last at
top.
You are now ready to start laying
shingles. The first course of shingles should be laid double and should extend % inch beyond
roof edge. The guidelines on
paper will align
overlap which each course will have. The last rows at
top will have to be cut; and a strip of granulated roofing paper, a metal cap, or a ridge piece, or shingles laid edgewise will be required to finish
top as shown in
illustration.
Wood shingles are laid much as asphalt shingles are except that they are not butted on
sides. Leave a %-inch space between
shingles. The ridge piece can be made of wood strips as shown in
illustration.
Roll roofing is one of
easiest types to apply. The accompanying illustration shows how this is done. You'll note that there is an overlap that is cemented down and nailed. This overlap varies with
type of roofing felt used.
One type has half of
width granulated,
remainder heavy felt. The granulated section is left exposed, and
felt part is cemented and nailed. This type can also be used on roofs having only enough pitch to drain
water, provided that
roofing boards are first covered with roofing mastic.
Flat or pitched roofs can be covered with a number of materials, but one of
least expensive methods is to build up
roof with a number of layers of roofing felt saturated with asphalt binder. The illustration shows how this is done. A cold roofing compound or hot pitch may be used as a binder.
Regardless of
above directions, be sure to follow
manufacturer's directions for applying his particular roofing material.
