DIY PROJECT GUIDE

Roofing Project Planning Guide

Plan material quantities before ordering shingles, underlayment, flashing, ridge materials, and accessories.

1. Break the roof into sections

Measure each rectangular roof plane separately. Roofs with dormers, valleys, hips, or additions are easier to estimate as several simple sections instead of one complicated shape.

2. Account for slope

Roof pitch increases the actual surface area compared with the building footprint. The HoneyDoPlanner roofing calculator uses the rise-per-12 pitch to apply a slope multiplier.

3. Add practical waste

Waste comes from cuts, starter courses, valleys, hips, and damaged shingles. Simple roofs may need less extra material than complex roofs. Product instructions and project geometry should guide the final allowance.

4. Build the full material list

Field shingles
Starter shingles
Ridge or hip caps
Underlayment
Ice and water membrane where required
Drip edge and flashing
Roofing nails
Ventilation components

5. Verify local requirements

Roofing work can involve fall hazards, structural issues, permits, weatherproofing, and local code requirements. Confirm applicable rules and use qualified help where the project exceeds your experience or safe working conditions.
