Residential Roofing Takeoff Overview
Asphalt Shingles are one of the most common roofing materials because they are cost-effective and work in nearly all climates.
What do you Get?
You will receive editable Excel Spreadsheet Material lists with a detailed breakdown of the quantities and usage within the model. With Archidiem, you get 3-in-1 Reports automatically.
In addition, you will receive color-coded markups of your PDF plans useful for auditing the areas we considered for your takeoff.
There are typically two major types of asphalt roof shingles.
- Thinner, less expensive, typically a single layer of asphalt
- Made with cutouts that make it appear as though three shingles are installed.
- Standard with a 25-year limited material warranty, a 60-mph wind warranty, and a 10-year algae warranty.
Dimensional aka Architectural Shingles
- Made from multiple layers of asphalt laminated together to give the shingle a more dimensional look.
- Do not have cutouts and may contain extra asphalt.
- Limited lifetime usually has a 110 or 130 mph wind warranty, lasts longer than 3-tab shingles, and may also include other benefits such as a lifetime algae warranty or a longer transferrable period.
- Most common as a limited lifetime dimensional shingle is just fractionally more expensive than a traditional 3-tab shingle.
Asphalt Shingle Roof Components
The illustration below shows the different layers of a typical asphalt shingle roof. The roof deck sheathing is covered with underlayment, usually tarred felt paper or a synthetic membrane. Metal Drip edge is applied along the eaves and rake edges. A row of starter shingles goes on along the bottom edge, with the shingle courses applied over that.
Here are the key components of your asphalt shingle roof included in our takeoffs.
- Typically installed on single-family homes with and sloped roofs
- An asphalt shingle roof is made of either fiberglass or organic materials.
- Fiberglass shingle is coated with a protective resin while organic asphalt shingles are made of felt paper with an asphalt coating.
- Provide the primary water-shedding surface for your roof as well.
- Roof underlayment adds another protective layer between your shingles and your home.
- Supports the stability of the roof and ensures that roof leaks and debris will not enter the home.
- Historically either 15 lb. or 30 lb. felt or newer synthetic-based underlayments which are stronger and lay flatter than felt options.
- Ensure that your asphalt shingles are properly installed.
- Keeps shingles in place by providing the first layer of sealant that prevents shingle blow-offs and water penetration from occurring.
- Typically required to maintain the manufacturer’s wind warranty.
Ice and Water Barriers
- In colder climates play a vital part by protecting areas vulnerable to water penetration, such as the valleys, asphalt shingles, and chimneys.
- Protect against ice dams that can sometimes form above the overhangs at the bottom of the roof.
- Often recommended or required around penetrations such as pipe collars, skylights, vents, etc.
Hip and Ridge Products
- Enhancing the roof’s design while increasing its functionality.
- Factory designed and often required to maintain the warranty.
Metal Roof Flashing
- Drip Edge protects eave and rake edges from water infiltration required per IRC 2012 edition or later.
- Valley Flashing prevents rainwater from crossing one roof plane to under another plane.
- Dormer, Chimney, and Kick-out Flashing shed water away from the connections between roofs, walls, chimneys, and other building assemblies.
