Building fire damage: fire damage assessment, fire damage repair priorities, fire amage minimization. This fire damage home page provides links to in-depth articles on a variety of building defects, systems, or components that are associated with extra risk of fire; we also discuss fire damage assessment. This article also discusses how fire damage and mold damage might be recognized in a building and how we might distinguish between black stains and white sealant paints used in both fire damage repair and mold remediation projects. In a separate section we discuss problems of wildfire damage risks to homes and how to minimize the risk of wildfire damage.

Recent leak history: March 2011 – lots of snow and then + 5 degrees Celsius- our roof started leaking and water was leaking in our front door frame.
9th April 2011 – The seller informed us that there was a fire at the construction stage of the house 28 years ago and that is what the black is all about in the roof...They painted over it to seal in the smell.
So we have two different diagnoses of these black and painted areas: mold or fire. What do I do now?
A competent onsite inspection by an expert - a real one who knows both mold and fire damage - usually finds additional clues that help accurately diagnose a problem.
Also your photos are less than one one thousandth of what I'd look at if I were inspecting the building, so any opinion I give is of necessity incomplete..
That said, here are some things to consider:
Given that the (apparently) vertical wall in this last photo is black with something, an astute home inspector who had access to this area during a pre-purchase home inspection would be expected to observe and comment on that anomaly and to warn you of its possible consequences.
Some Specific Suggestions for Handling Mold & Fire Traces in a Home
Our photo (left) illustrates extensive fire damage to a home at which the fire originated in a (probably creosote laden) metal chimney venting an overheated woodstove, spread to the building's roof and burned back down the building's wall. A combination of weather conditions and speed with which demolition and repairs began seemed to avoid a concern for mold contamination associated with water used to extinguish this fire.

Fire-resistant windows & doors for homes in wildfire-prone areas
If you have occasion to replace windows or doors on your home, when choosing new windows look for dual-glazed tempered glass glazing - a material that is more heat and ember resistant than single pane windows.
