Flat Roof Attic Insulation Tips

Because of relatively easy access, the attic is often the first area of the house to be insulated. attic insulation is also a good place to insulate a house with existing insulation. However, it is important to check that the existing insulation in the attic is in good condition and has a high R-value. It is also helpful to evaluate the existing air sealing and ventilation conditions in the attic space and, if necessary, improve them. In particular, it is a good idea to examine the attic space during or after a cold snap for moisture problems. A heavy frost buildup in mid-winter may indicate inadequate ventilation or an insufficient insulation depth.

Flat Roof Attic Insulation Tips Every Homeowner Should Know

If there is a significant amount of existing insulation in the attic, consider increasing it with polyethylene sheeting or spray foam. This method can be less costly than other methods and involves fewer seams. It is possible to insulate between the collar ties and the attic floor with this technique, but it is important to seal all air leaks between the ceiling and the wall plates below the attic.

If the attic is very cramped and there are already considerable obstructions in the joist space, such as chimneys or plumbing stacks, it may be impractical to increase insulation levels. However, the existing insulation may still be adequate if the air leakage between the attic and the house below is properly sealed and there are working soffit vents in the attic area.
