Coal tar roofing svstems are tne time proven roofing systems for level and low sloped roofs. Coai Tar Bitumen provides numerous advantages to an owner The superior performance of coal tar roofing systems m the areas listed below make coal tar roofing systems uniaue m the roofing industry 1. Coat Tar Bitumen has natural resistance to water, atr and water vapor penetration. A tigm moiecutar structure enables Coal Tar Bitumen to resist water penetration and oxiaation of tne roof surface 2. Another feature of coal tar roofing is its sellhealing ability. Aihgatormg and hairime cracks common to most matenais eventually cause damage to the roofing membrane Coal Tar Bitumen has a property known as cold flow which automatically corrects these conditions before serious damage takes place This coidflow' feature neats small mechanical fractures at normal temperatures 3. Application improvements. Because Koppers has expertise m the Chemistry of aromatic coal tars Coal Tar Bitumen was deveiooed with tne beneficial features of low fume evolution at application temperatures thus reducing potential irritation during application These features reoresem significant improvements which are in consort with the aims of government labor ano industry m the areas of reduced air ooiiudon anc improved worker conditions Uses 1.

Purpose: Tar: Procedure: Many factors play a cart in the service life of a roof Some factors are uncontrollable Others can definitely oe controlled There are some aspects of roof degradation that will follow a recognized path ana the end result can be predicted The normal degradation of a built-up roof oegms at the top surface This is unaerstanaaoie since it is the top surface that s subjected to the deleterious elements of the atmosphere As soon as a roofing bitumen ts exposed to these elements, an age hardening process begins As the softening point of the bitumen increases, cold flow properties Oimimsn ana resistance to moisture penetration decreases The volatizmg or subliming of a roofing bitumen takes its toll on me performance characteristics of me bitumen At some time prior to tne roof reaching the point wnen maintenance is no longer `easibie. preventive maintenance sho. d be established. even though the roof mav not be leaking After considering the age. type of bitumen used to construct me roof and general condition the use of Koppers Roof Resaturants offers an effective means of implementing preventive roof maintenance Koppm Roof Rasaturant 410 Mas a ease of coal tar roofing Bitumen, blended with nonvolatile oils and selected fibers.

Koppers Fiber Coating 415 is a tar base product specially formulated to meet Federal Specification SS-C-540 Fiber Coating 415 contains properly selected fibers plus pene trating oils Asphalt: Koppers Roof Resaturant 425 is an asphalt resaturant designed to provide a softening effect to the dried roofing felts. Roof Resaturant 425 is a blend of asphalt and oils compined with fibers to provide a product suitable for flat or sloped graveled roofs 1. All loose gravel must be removed from roof If existing gravel is to be reused, it must oe washed free of silt 2. Silt is removed with water pressure, air pressure or vacuuming. If water is used tne roof must be allowed to dry completely belore proceeding 3. Drains are covered with screens 10 prevent clogging of tne drain system 4. After the root is properly cleaned all necessary repairs are made with compatible materials. 5. Koppers Roof Resaturant is applied evenly onto root at the rate of seven i7) gallons per square The application rate may vary with tne condition of tne roof S. Gravel or slag is applied to cover me Koppers Roof Resaturant Gravel snail oe m Ihe range, and must be washed Care must be taxen to avoid exceeding weight limits ol tne root deck Gravel should be applied immediately after application of resaturant 7.
