Roof Space / Loft / Roof Void
If possible, it is good to have a look in the roof void.
Modern properties will usually be constructed of timber trusses which were manufactured in a factory.
You should check that no alterations have been made to the trusses and that they are straight and true.
Also check for any signs of condensation damage.
In older properties, timber rafters and purlins should again, be straight with no signs of sagging or distortion.
Check for any signs of active woodworm or dry rot.
Modern plasterboard ceilings rarely cause any significant concern unless water damage has occurred.
Hairline cracks are common between the sections of plasterboard.
In older properties some areas of lath and plaster may remain. Lath and plaster tends to have irregular shaped cracks and may bulge or distort.
Lath and plaster can fail with no prior notice and is difficult and expensive to repair.
Walls and Partitions
Check walls and partitions are straight and true. Ensure no obvious signs of visible dampness or plaster damage is occurring at lower levels to ground floor walls.
Confirm no loadbearing walls have been removed without Building Regulation consents.
Where the property has solid floors, ensure that no gaps have occurred between the concrete floor and skirting board which would indicate the floor slab has dropped.
Timber floors should be level and sound. Any flex or springiness may indicate dry rot or timber defects beneath.
Make sure any fireplaces which appear to be in use have a full chimney breast between the fireplace and chimney pot. If any sections of chimney breast have been removed this should have Building Regulation consents.
