Use the Calculator for Core Quantities
The roofing squares calculator estimates squares, shingle bundles, waste, and underlayment rolls. This checklist explains the other material categories homeowners should look for in a roof estimate.
Basic Shingle Roof Material Checklist
| Material | Why it matters |
|---|---|
| Field shingles | Main roof covering on the roof planes. |
| Starter shingles | Help seal and secure shingle edges at eaves and rakes. |
| Ridge cap shingles | Cover ridges and hips where roof planes meet. |
| Underlayment | Secondary layer over the roof deck beneath shingles. |
| Ice and water shield | Self-adhered membrane for vulnerable areas where required or recommended. |
| Drip edge | Metal edge detail that helps direct water away from fascia and decking. |
| Flashing | Protects walls, chimneys, valleys, and transitions from water intrusion. |
| Pipe boots and vents | Seal penetrations and support ventilation. |
| Fasteners and sealant | Product-specific installation components. |
Materials That Are Easy to Miss
Homeowners often focus on shingles, but roof failures often happen at details: flashing, pipe boots, valleys, drip edges, ventilation, and wall transitions. A lower quote may not be better if it leaves out important system components.
Questions to Ask Before Ordering or Signing
Ask which shingle product is included, whether starter and ridge products are separate, what underlayment is used, how flashing is handled, how damaged decking is priced, and whether ventilation changes are included.
