This is due to the fact that most mobile homes have very little space between the ceiling and roofing so the manufacturers figure why bother with it however there is enough room up there for a little storage or attic access for repair.
Do most houses have an access panel to the attic.
Also the access may a small door the wall of an upper story room or high in the wall between the garage and house.
Some experts say that vents used to be required to remove moisture entering the attic through leaks but that modern homes have sealed attics and really don t require venting.
Manufactured houses do not usually have attic access because of the limited space between the ceiling and roof.
Some very old homes have attic access only through a removable vent panel at a gable end wall of the roof.
Sometimes a home inspector will open a secured panel if the seller gives permission and holds the inspector harmless for any damage.
There is usually mitered casing around the edge to hold the panel up in the air.
Opening the ceiling to gain access is not a difficult process.
The first thing you need to do is seal this trim to the ceiling.
So you should not consider buying a house that has no way to get into the attic.
Interestingly most manufactured homes do not come with an attic access for new homeowners.
But otherwise get the seller.
If the access panel is locked nailed or caulked shut then ask the seller to get it opened for you.
It s against most building codes to vent anything into the attic plus if warm moist air is released into the attic again you re going to have a problem with mould.
