The damage is visible, but safe access is limited
Start with the wider scene from a protected location: the tree, the affected part of the property and the surrounding area. Tell the insurer which details cannot yet be photographed. Record the access instructions given by responders and ask how the insurer wants later documentation handled. An incomplete safe record is preferable to taking risks to create a more dramatic image.
Notice next: Keep the original photographs and a brief note explaining the viewpoint and access limits. Ask the insurer what it needs next after hazards are controlled.
