BUILT-'UP ROOFING AND METHOD 0F APPLICATION l:Application led March 29, 1926. Serial No. 98,327. A
Our invention relates to built-up roofing 4and method of application thereof. V Heretofore built-up roofing has been applied by the 61 application on the roof of a sheet or layer of bituminous saturated paper or felt and then mopping over such layer a hot bituminous bonding and protective material applying a second layer, mopping over that a second application of hot bituminousbonding and the a plication of the saturated felt or paper a1i)d the hot bituminous bonding and protective material until the desired thickness of roofing has been applied. Such method and application of roofing requires facilities for eating the bituminous lmaterial which is usually done on the ground and then the hotmaterial is raised in pails or buckets to the roof where it was mopped on or applied by the workman. lThis method has many objections including the cost of` heatingr and handling the bituminous material. It is difficult by this method to get the coating of the hot bituminous material evenly applied over the surface and to prevent air pockets or bubbles being formed, due to air being entrapped, in the. hot bituminous material. While it is being mopped on the roofing preparatory to the application of the next above sheet of saturated paper or felt. We have overcome the objections to this method of application, and, have provided a built-up roofing which is superior to and more easily applied than the builtfup rooiings heretofore 'known in the art, have dispensed with the use of heating facilities,'thereby reducing the co'st of application and obtaining a more uniform built-up roofing, having provided a more even distribution of the bituminous material between the layers, and have overcome the objectionable entrapment of air bubbles or air pockets between layers of the saturated felt or paper. By our invention we provide a sheetor paper saturated or impregnated with bituminous material such as heretofore used for built-up roongs and form on one or both sides and integral therewith a coating of a bituminous material such as asphalt, coal tar, etc., which is distributed evenly .over the sheet of saturated felt or paper in the factory. The coating which we prefer to use is a bituminous material of a character that when cool or at atmospheric -temperature will permit the sheet of saturated paper or felt upon which the coating is applied to be rolled without cracking and which will not crack when the paper is unrolled. Such coating is-to be of a character that a liquid solvent applied to its surface by a mop, a brush, or a light spray, will dissolve the surface ofthe coat` ing so as to provide a tacky or adhesive surface to which the next sheet or ply of saturated paper or felt will adhere. We also provlde for use with the roong material referred to a solvent which can be readily applied either by brush, mop, or spray to the surface of the coating. Such solvent is pre-` ferably one with a high solvent ower so that a very small quantity will rea ily cause the surface of the coating to become tacky or adhesive. Such solvents as napththa,
gasoline and kerosene have been found satl isfactory for bituminous coatings of asphalt. We however do not limit ourselves to the use of as halt as a saturant or coating 0r the use of t e solvents referred to as any suit` as asphalt. C is a similar coating on the bottom of the saturated felt- A, which coat. ing C is of like material to Athe coating B. The coating layers B and C are applied to the saturated felt A in the factory and the roofing material-is rolled and forwarded to the place of application. By our method of applicationthe solvent is applied to either or both ofthe coatings B and C as the roll of roonff material is being laid. This solvent wou'l-)d be applied as shown in the drawing to the right of the roll of material which forms the top ply ofrooiing. As the solvent is applied to either or both of the coatings B and C and the material is brought into Contact by unrolling of the roofin material, the coatings which are in a tac yor adhesive condition securely hold the layers urated and coated rooingmaterial is laid and the coating on fixed inplace by nailing or 1f it is desired it may be cemented to the roof, in which case we preferably use a saturated roofing material which has been coated on both sides and as the roll is laid over the roof applied by the workman vto the surface of the under side .of the sheet thereby partially dissolving same and causing its surface to become adhesive and tacky. The result is that when the tracky or adhesive surface comes in contact with the roof it cements itself thereto and becomes fixed in place. The next above layer, of saturated and coated roofin material is then applied by havingthe wor an mop the cold solvent on the surface of the first layer just ahead of the roll of the second layer of saturated and'co'atedroong material as it is being unrolled so that the coating on the up er surface of the first sheet is partiall solved, and the surface becomes tac y or adhesive and readily. cements itself to the second layer as it is unrolled and brought into contact with the coating on the first layer. In this way it will be seen4 that the roll of roofing material as it is unrolled passes over the portion ofthe material that is being cemented to the next below layer and thereby tends to force out any bubbles, and prevent the formation of air pockets between the layers. The third layer of felt is applied in a similar manner and likewise the fourth, and fifth depending on the number required. The coating having been applied in the factory will be of even thickness and the result will be a more uniform thickness of the finished built-up roofing. If it is desired to form on the surface of the roof a gravel or granular surface such result may be obtained in two ways, either the coating on the upper surface may be dissolved by the solvent being applied so as to make the coating tacky or adhesive and then the gravel or granular material applied, or if desired the ip ply could be a layerof granular surface roofing material having the granular material applied thereby more a solvent is after the coating is set, into a roll, unrolling the roll onto the roofing support while applying a solvent to the coated sheet material slightly in advance of the line of tangency l between the roll and the roofing support, then unrolling a second roll of the coated sheet material while applyinoa solvent to the surfaceof the material slightly in advance ofthe line of tangency'between the roll and the upper surface of the' first sheet, whereby in applying the sheet material to the surface below, any air bubbles or surplus solvent will be forced out from between the approaching surfaces due to the curvature of the sheet being applied and the weight of the unrolled portion of the sheet.
In testimony whereof, wek have signed our names to this specification.
