Roofing Project Tips

📏 Accurate Measurements

Measure your home's footprint and account for overhangs. Use pitch multipliers to calculate true roof area.

🌦️ Weather Planning

Plan roofing projects during dry seasons. Allow 1-3 days for completion depending on roof size.

📦 Order Extra Materials

Order 10-15% extra shingles for waste, cuts, and future repairs. Keep leftover shingles for later use.

🔍 Inspect Before Starting

Check roof deck for damage. Replace any rotten or damaged decking before installing new roofing.

🛡️ Safety First

Roofing is dangerous work. Consider hiring professionals for steep roofs or if you're uncomfortable with heights.
