What happens here

The video starts with an introduction to the various components of a roof. The presenter identifies the core structural 'Deck Sheathing' (made of OSB) and then introduces the protective layers: a white metal 'Apron' (acting as a drip edge) at the eave, an 'Aluminum Fascia' (fascia cover) positioned vertically below the apron, 'Ice and Water Shield' for waterproofing, and 'Synthetic Felt' as an additional underlayment. He also shows the 'Drip Edge' (a separate component, not to be confused with the 'Apron' in his model), 'Starter Strip' shingles, 'Shingles' themselves, 'Step Flashing' for wall junctions, and a 'Gutter' for water collection.

Goal: Identify and understand the function of each roof component.

Tools and materials

  • Apron — A white metal piece installed at the eave, serving similar function to a drip edge
  • Deck Sheathing — The structural base of the roof, made of oriented strand board (OSB)
  • Drip Edge — A metal flashing installed at the edge of the roof to direct water away from the fascia and into the gutter
  • Fascia — A white aluminum cover installed vertically along the eave, protecting the fascia board
  • Gutter — A channel installed at the eave to collect and divert rainwater
  • Ice and Water Shield — A self-adhering membrane that provides a waterproof barrier, typically extending three feet past the conditioned space
  • Shingles — The primary weather-resistant layer of the roof
  • Starter Strip
  • Step Flashing — L-shaped metal pieces used to waterproof roof-to-wall intersections
  • Synthetic Felt — A lightweight underlayment applied over the ice and water shield, higher up the roof, to provide additional protection

What they say

Hide

Roofdeck, apron, fascia. >> [snorts] >> Ice and water shield. This typically goes 3 ft past your conditioned space. Synthetic felt. This will go higher on the roof above the ice and water. This also gets cap nailed. Drip edge. Starter strip. Tar side up to adhere to the shingles. Don't nail too high, usually 2 to 3 in. Shingles. Overlap the drip edge or apron a half inch. Can nail between the wide lines or where the lines are tighter, it overlaps so you'll get better hold.
