„ This invention relates to rooiing construction
elements and rooñngs made therefrom, and more
particularly to the construction'oi.’` rooiing ele
ments such as shingle strips comprising a base
5 sheet of felt or like ñbrous material saturated
with liquid bitumen, such as asphalt.
As these strips are ordinarily constructed, a
coating of asphalt, or similar adhesive and water
prooñng material, is applied to the top of the
1_0 strip, and granules of slate or similar material
are embedded in this coating for the purpose of
increasing the weather-resisting qualities oi.' the
product. Where ornamentation is desired, this
result may be secured by using coloredl granules.l
15 As usually constructed, the shingle strips pre
sent a flat and unattractive appearance when laid
A upon a roof. It is the general purpose and object`
' , of my invention to impart a more pleasingap- `
pearance to these strips; to increase the strength,
20 rigidity, and wearing qualities thereof; and to en
y able the exposed portions the better to withstand
,L the'eiîects of weather and the lifting effects of
the wind.
I accomplish these objects in and through the
25 construction of a special form of so-called thick
butt shingle strips, which will be described in
Application July 24, 1937, serial No. 155,500

end of the strip approximately half the height or
width of the same. This coating has particles of
' granular material, such as slate, applied thereto
and embedded therein, Aas indicated ‘at 9. .
Each of the strips as thus constructed is pro- 5
vided with slots I0 extending upwardly from the
bottom edge thereof and terminating below the
upper end of the coating 8, 9. In practice, in
strips having a height or width of 12 inches, the
coating B, 9 extends upwardly about 6 inches 10
from the bottom of the strip while the slots I0
extend upwardly approximately 5 inches. This
will enable the bottom of a strip Ii in the next
uppercourse to extend downwardly as far as the
tops of the slots in the next lower course and pro- 15
vide at the same time a covering for the nails i2
by which the strips in such lower courses are se
cured to the roof frame. It will be noted further
that, when the strips are nailed in the usual
manner-at a short distance above the tops of 20
the slots Ill-¿the nails will not only be covered
by the bottoms of the strips in the next course`
above, but will be driven through the thickest
and strongest portion of each strip, as will be
f indicated at I2.

cover a strip constituting an individual shingle 55
