The heel of your roof truss is very important

We could quickly plunge right into a conversation and discussion about insulating on top of the exterior wall and how that impacts the heel of your roof.  That would be a great idea except I am betting that many folks aren’t quite sure what the “Heel” really is.

Roof systems are built from several component parts:

  • Rafters – the roof rafters are the long beams that go from the top of the wall to the peak of the roof.
  • Collar Ties – a collar tie connects or ties two rafters together with a horizontal beam up towards the peak creating triangles that are not able to flex
  • Top Plates – this is the piece of lumber that the roof system sits on at the top of the exterior wall
  • Truss – is an engineered system that displaces weight and creates strength
  • Heel – the truss’ heel is that part of the truss rafter that sits on top of the exterior wall.
  • A Raised Heel creates extra room for additional insulation.

Raised Heels allow more insulation to be added at the very top of the exterior wall.  Surprisingly this is a critical area that is far too often overlooked.  By not adding additional insulation at this critical point cold spots occur.  As those cold spots appear they also come in contact with warm moist air from inside the heated home.  That ends up being a terrific place for Mold to start growing.

We could go on and on about how nasty and harmful mold can be for you and your family.

If you have ever looked up at the top of the outside wall as it touches the ceiling and seen black spots that is because mold is growing there.  That mold is allowed to grow because the house was not insulated properly.

Proper insulation is needed and that can happen with a well designed Raised Heel.
