Mushrooms Growing On Roof

Fungus so bad there are now mushrooms growing out of the floors of the gym.
Mushrooms growing on roof. The mushrooms are growing on my rental house not many only a small side of the house but persistent over the 3 years in small quantity since i ve owned this rental. It may be from a plumbing leak a roof leak or a severe lack of ventilation. For years liz says they ve been plagued by a bad roof. Mushrooms in the house mushrooms growing indoors present a classic sign of a moisture problem.
It s a combination of algae and fungus and usually has a light mint green color. In this situation first the leak must be fixed and secondly the roof must be treated also in order to successfully kill the root of the infestation. If you have an area where a tree used to stand even if the stump is gone the dead roots underground may encourage mushroom growth. If the stump is still there you can have it removed.
If it s gone just keep the area well raked and aerated to improve drainage. Correcting the moisture problem is the first step in the eradication procedure. From your description you may have lichen growing on the surface of your roof. It s not unusual to see mushrooms growing in the basement that derive their moisture from a rooftop leak.
It doesn t trap as much water against the surface of the roof as moss but it can be acidic and has strands that can penetrate into the shingles.
