Dormer Calculators

• Surface Area of Dormers: This computes the roofing surface area for dormers based on the dimensions and number of dormers.
• Metal for Dormers: This computes the metal roof materials (panels, ridge cap and trim) for one or more roof dormers based on the dimensions
• Screws for Metal Dormers: This computes the number of metal panels screws needed for one or more roof metal paneled dormers based on the dimensions.
• 4x8s for Dormers: This computes the number of 4x8 sheathing needed for one or more roof dormers based on the dimensions.
• Shingles for Dormers: This computes the number of shingle bundles needed for one or more roof dormers based on the dimensions. It also includes ridge shingles, valley lengths for flashing, and roofing nails.
• Underlayment for Dormers: This computes the amount of underlayment needed and estimates the cost of underlayment materials.
• Roofing Nails for Dormers: This computes the number and weight of roofing nails needed for one or more roof dormers based on the dimensions.
• Purlins for Dormers: This computes the total number and length of purlins (roof support boards) for needed for one or more roof dormers based on the dimensions.
• Dormer Geometries: This computes the diagram measurements for a dormer based on the dimension.
