We bought a house 15 years ago with an addition. The prior owner obviously did not consult an architect, however, we thought we could live with the bad design until the cracks started. Ceilings first then the corners of the rooms and now the connection point of the buildings. We had the roof replaced and the roofer said that the shingles were cracked horizontally indicating a problem with roof support. The roof does not have much pitch and attic is really a crawl space, but it would explain the problems in the addition.
How do we add support to this roof? Help! We want to sell and need to correct this issue to get top dollar. We need to add more insulation up there too and check for ventilation in the eves (there is a ridge vent, but that doesn't seem to do the trick. Oh, I forgot, we are retired on a fixed income and don't have much money.
