Roofing Estimate Tips

1 roofing square = 100 sqft of roof area
Add 10-15% waste factor for cuts and hip/valley roofs
Steep roofs (8/12+) typically cost 15-25% more
Second-layer tear-offs cost more than single-layer
Check local permit costs -- they vary widely
Ice & water shield is required in cold climates
