Common Questions

Standard reroofing permits for single-family homes start at a base fee of approximately $256.62, but total costs typically range from $500 to $1,500 once plan review surcharges and street space permits for debris bins are included.

Yes, significantly. Projects in dense or affluent neighborhoods like Pacific Heights or Nob Hill can cost 30% to 50% more than in the Sunset or Richmond districts due to difficult street access, limited staging areas, and higher insurance requirements.

The Department of Building Inspection (DBI) can issue penalties ranging from $3,000 to $10,000 for unpermitted work. Additionally, unpermitted roofs often void homeowner insurance policies and must be retroactively permitted during home sales.

Under California's Title 24 Energy Code, most San Francisco roof replacements must use 'cool roof' materials with high solar reflectance. This requirement is mandatory for all permits and can add 5-10% to material costs compared to non-compliant shingles.
