DIY Roof Replacement Cost Breakdown (Garage Re-Roof Start to Finish)

Replacing a roof is inevitable—whether you DIY, hire it out, or do a hybrid. In this video I re-roof a 28' × 14' detached garage (784 sq ft ≈ 8 squares): tear off two layers, replace damaged decking, install drip edge, ice & water, synthetic underlayment, starter strips, and architectural shingles. I share full materials, disposal, and labor costs, plus cost per roofing square so you can estimate your own project. My numbers (9 squares purchased for buffer): DIY materials + disposal: $2,267 → $252/square Hybrid (my actual, +$825 labor): $2,789 → $310/square Pro quotes (avg): $4,400 → $485/square Tips: inspect decking/fascia during tear-off, replace damaged OSB (I matched 1/2", recommend 5/8" where possible), use drip edge around the perimeter, and follow local code for ice & water and underlayment. Always use fall protection and comply with local codes/permits. #roofing #diyhomeimprovement #asphaltshingles #costbreakdown
