Retrofit flat roof insulation.

We go right over the existing shingles. See http solaralberta ca pdfs harold 20orr pdf we have done several roofs this way 1. We have done many roof retrofits with a structural insulated panel nail base panel. The house has a flat epdm roof open chord roof trusses no ventilation and r 30 fiberglass batts with dubious installation quality wiring interrupts can lights swamp cooler ducts.

Retrofit an existing flat roof to improve thermal water and air control performance as follows. Cover the roof with 6mil poly sealed at the wall line to the vb in the wall. To produce a hot roof rigid insulation is fitted outside above the weatherproofing. Our insulation for existing flat roofs is ideal for extensions dormer roofs and includes a layer of either 25 50 75 or 100mm insulation board.

Cold roof systems are highly inadvisable as insulation from the inside will inevitably lead to the formation of condensation. Make the necessary corrections to the roof framing and decking prior to beginning the new work. This is then covered with a further weatherproofing layer. With a flat roof however this becomes a major concern.

Different types of roofing insulation exist including blanket insulation blown insulation and rigid insulation. I d like to add insulation to this truss space.

This benefit alone many times allows the metal retrofit roof system to pay for itself within 10 to 15 years.
