Our garage is a single brick detached building with a pitched roof. Inside it is just open up to the roof with exposed timber roof trusses. Tiled roof (not proper slates, not sure what they're made of) and a membrane underneath.
Over the colder months everything in there gets damp. I've laid some patches of boards to store some boxes in the roof space but it is mainly still open. Some of the boards have begun to go moldy, the roof trusses are fine.
On the house soffits there are vents all round, on the garage there are non. The only ventilation in the garage is through the gaps in the garage door which ideally I'd like to seal up to help heating.
The mortar joints in the brickwork get mildly damp via penetrating damp as it's only single skin but the walls aren't wet, concrete floor is bone dry.
I'd ideally like to insulate and board in there, just the ceiling to start with and to insulate the garage door to make it a bit more bearable in the winter, I have heating in there (diesel heater) but any heat just goes straight into the roof space.
Question is, should there be vents in the garage soffits, and second question, if I board in there to make a ceiling will I need to put soffit vents in to ventilate the roof trusses as there would be in a loft?
