Replying to [davejacks]:
Hello there,
As for the roofing products, the biggest market for that is actually Europe and USA. You didn´t mention what type of roofing you are selling, aluminium types or other.
Currently anything that helps to dampen the heat inside the house is quiet in.
For roofing products you need to get in touch with builders and architects. You need to have a good price calcuations and in the building industry its quiet common to have payments of up to 90 days.
Germany is a good buyer of roofing, so is Austria, Italy, and the Ex-Jugoslavien states.
Hope that helps you out.
