Known in the trade as vertical racking or staggering this how to lay shingles method enables the roofer to install a single column of shingles all the way to the peak without the wasted. Gable end detail overhang cut and then rebuilt to hide the thickness of the over roofing rigid insulation. Note that table r806 5 indicates the amount of insulation above the roof deck or air impermeable insulation below the roof deck required for condensation control assuming minimum required total insulation as indicated in section n1102 building thermal envelope. The structural roof deck is designed flat the celcore roof deck insulation system can be placed in a manner which provides positive slope for roof top drainage.

The second course starts a stair. May 8 2020 explore tui olsson s board rigid foam insulation on pinterest. Stair stepping shingle courses the first shingle course is a full row of 3 tab shingles installed along the bottom edge of the roof flush with the starter strip. Placement slopes are created by stair stepping the encapsulated eps panels placed within the insulating concrete deck.

With this kind of roof the insulation follows the slope of the roof. Many pros shingle in a vertical line up the roof because it s much faster. Eps is also the most inexpensive of the three types of rigid foam insulation while also meeting the required building and energy codes. However most cathedral ceilings and low slope flat roofs are insulated roof assemblies.

Attic drop down stair shall be fully gasketed for a snug fit. This section outlines the conditions for unvented attic roof assemblies. A roof over a vented unconditioned attic does not need to include any insulation. It can be applied on the roof floor and walls and it s most widely used in structural insulated panels and insulated concrete forms.

However gaps in weatherstripping to accommodate hinge hardware shall be acceptable factory made attic drop down stair assemblies that are fully gasketed and include a rigid insulation panel much like an exterior insulated door are a great simple solution. Eps is by far the most versatile of the three rigid insulation options. There are lots of different ways to insulate this.
