White mould on roofing felt.

Mould white blue or black spots on timber lining felt masonry. Common food sources for white mold include wood drywall carpeting laminate insulation and any other organic carbon rich material. I ll assume you mean condensation on the underside of the roofing felt which means there is moist air in the loft space otherwise there could be no condensation this needs to be vented. The best temperatures in which mold grows is between 2 and 40 degrees celsius.

They can appear as numerous white spots or blots or even small fibers when the growth is uncontrollable. Efflorescence occurs when water moves through a masonry structure bringing unbounded salts to the surface. White mold commonly looks like bright fluff like spots that spread on numbers of surfaces from plants to wood and even bread. When seeing under the microscope the body of the mold will look like filaments.

Take the baking soda and cover the area where the mold is on your felt fabric. Like other molds white mold grows due to high moisture levels combined with the presence of a food source and the right temperature. White mold growth provides an additional challenge because it is often confused with efflorescence a crystalline growth structure found on concrete and masonry surfaces. You want the area to be free from anything that can add to or create a new problem.

Roofing felt is comprised of a base made from natural materials such as wood cellulose or synthetic ones such as fiberglass or polyester and then coated or saturated with a protective coating such as bitumen asphalt which repels water but still allows the product to breathe. When the water evaporates a white fluffy structure is left behind.
