Attic Ventilation/Mold
I bought this house new in 2005 and have lived in it since that time. The temperature where I live is around 23 in the winter to 80 (Fahrenheit) in the summer. (Near the coast).
Here are some pictures from my attic. As you can see there is black (mold?) on the inside of the roof. On the sunny side it looks like it has been "burned" away, on the shaded side it is still very black. It has been there at least for at least 4 years.
What would be the best way to remove/clean it from this area?
There is very limited ventilation in this attic (some vents along eave and one in the roof).
Also, I was considering installing a wood burning stove, with an interior chimney passing through this attic space. This would add significant heat to this attic.
If I decide not to install the stove/chimney would it be wise to try and open more vent outlets? If I decide to go ahead with the stove/chimney installation, how will it affect the issue of ventilation in the this attic? It seems it would take alot of vents to cool down the area with the heat that would come from the chimney.
Ice does form along the edges of the roof in winter. The air exchanger ducting also passes through this attic possibly adding heat in the winter.
Would there be enough heat from the chimney to melt ice that is presently building up along the edges in the winter?

I would suggest installing some gable vents. I like to install one in each gable end.... DEPENDS HOW THE ATTIC IS DESIGNED. You want the vents to blow out..... The soffit vents will draw air in.. Keeps air moving. When moisture/humidity just sits...its a breading ground for Mold and other things to grow.
I would not worry about heat coming from a chimney, if installed properly. There should be almost no heat... The hottest part of the of a chimney is right at the smoke shelf and 3 feet above it.. If you do decide, make sure you have a qualified company do the work. NOT a handy man.
