Asphalt

bitumenbituminoustarmac
Bitumen (asphalt or coal-tar pitch) is a mixed substance made up of organic liquids that are highly sticky, viscous, and waterproof.
Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs.

Tar paper

tarpaperfeltedimpregnated
Roofing felt (similar to tar paper) is the base material used to make roof shingles and roll roofing.
Tar paper is distinguished from roofing felt which is impregnated with asphalt instead of tar; but these two products are used the same way, and their names sometimes are used informally as synonyms.

Asphalt shingle

asphaltRoofing Materialsasphalt-shingle
However, the application of underlays may increase the roof temperature, which is the leading cause of ageing of asphalt shingles and felt paper wrinkles when it gets wet, which (rarely) shows through asphalt shingles.
All shingles were organic at first with the base material, called felt, being primarily cotton rag until the 1920s when cotton rag became more expensive and alternative materials were used.

Roof shingle

Roofing felt (similar to tar paper) is the base material used to make roof shingles and roll roofing.
Many shingle installations benefit from being placed on top of an underlayment material such as asphalt felt paper to prevent leaks even from wind driven rain and snow and ice dams in cold climates.

Sarking

Typical uses of felt paper are as an underlay(ment) (sarking) beneath other building materials, particularly roofing and siding materials, and is one type of membrane used in asphalt built up roofing (BUR) systems.

Deck (building)

deckdeckingdecks
The separation of the roof covering from the roof deck protects the roof covering from resins in some sheathing materials and cushions unevenness and old nails and splinters in re-roofing applications.

Ice dam (roof)

ice damsice damice damming
The underlayment also sheds water, which penetrates the roof covering from an ordinary leak, a leak from wind-driven rain or snow, wind damage to the roof covering, or ice dams.

Cotton paper

Organic felt paper has a base material made with formerly living materials such as rag fibre, hessian (burlap), or cellulose fibres (wood, or jute).

Tar

Rolls of base felt are pulled on rollers through large tanks of bitumen mixes until they are saturated with the tar-like bitumen mixture, producing rolls of water-resistant but breathable material.

Limestone

Modified bitumen is mixed with filler components such as limestone, sand, or polymers such as atactic polypropylene (APP) that gives rigidity and tear resistance or styrene-butadiene styrene (SBS), a rubber additive that gives more elastic benefits.
