Product description
Roofing felt is a crude paperboard impregnated with bituminous impregnating agents (tar, asphaltic bitumen); it is produced in web form and supplied in rolls. Both sides are covered with mineral materials (e.g. sand) in order to help prevent the coating from running off when exposed to heat or from sticking together in the rolls and to provide protection from atmospheric conditions. A distinction is drawn between tarred board and bitumen board.
Intended use
Roofing felt is used, among other things, for waterproofing roofs to prevent ingress of moisture.

Packaging
Roofing felt is transported in rolls (e.g. 70 kg, 1.20 m in length, diameter 30 cm) wrapped in paper or in bales in crates.

Transport
Symbols
 General cargo |
Means of transport
Ship, truck, railroad
Container transport
Subject to compliance with limits for the water content of goods, packaging and flooring, roofing felt may be transported in standard containers.
Cargo handling
It is imperative that roofing felt be protected from moisture (rain, snow etc.) during cargo handling, as there is a risk of damage caused by swelling.
In the event of incorrect handling during loading, unloading and storage, there is always a risk that the relatively mechanically sensitive goods will be damaged by snagging.
Stowage factor
|
2.12 – 2.35 m³/t (roofing felt in 70 kg rolls, wrapped in paper) [1] |
Stowage space requirements
cool, dry
Segregation
Marker pen/oil crayon (preferred)
Cargo securing
The cargo is best transported in a vertical position. If the rolls are stowed horizontally, they should be stowed only 2 – 3 layers deep in order to avoid sticking and distortion of the individual rolls.

Risk factors and loss prevention
RF Temperature
Roofing felt requires particular temperature, humidity/moisture and possibly ventilation conditions (SC VI) (storage climate conditions).
Most favorable travel temperature range: 0 – 25°C [1]
Optimum travel temperature: 20°C [1]
The product must be protected from heat sources and solar radiation as there is a risk of sticking.

RF Humidity/Moisture
Roofing felt requires particular temperature, humidity/moisture and possibly ventilation conditions (SC VI) (storage climate conditions) .
| Designation | Humidity/water content | Source |
| Relative humidity | 75% | [1] |
| Maximum equilibrium moisture content | 75% | [1] |
Roofing felt must be stored under dry and cool conditions.

RF Ventilation
Roofing felt requires particular temperature, humidity/moisture and possibly ventilation conditions (SC VI) (storage climate conditions) .
Recommended ventilation conditions: air exchange rate: 6 changes/hour (airing) in order to ensure the lowest possible temperatures or if there is a risk of damage to odor-sensitive goods.

RF Self-heating / Spontaneous combustion
Since roofing felt is a flammable material it should be protected from sparks and smoking must be strictly prohibited. Roofing felt can be ignited by a match flame. The ignition temperature is 365°C. When stacked, heat-induced spontaneous combustion is readily possible, with fresh roofing felt being at particular risk of spontaneous combustion.

RF Odor
| Active behavior | Roofing felt releases an unpleasant odor. |
| Passive behavior | Roofing felt is not odor-sensitive. |
Back to beginning
RF Contamination
| Active behavior | Roofing felt may cause contamination if the tar or bitumen layer is heated and liquefies. |
| Passive behavior | Roofing felt is not sensitive to contamination. |
Back to beginning
RF Mechanical influences
Roofing felt is sensitive to mechanical influences such as pressure, impact and friction.
