Roof City did an excellent job on my roof. They were professional, fast, efficient, and clean. They over- delivered on their promise to do a five- star job in two days, which included all materials and permits needed. They deserve a 10 star rating 🌟 ✨ 💫🌟✨💫🌟✨💫☀️🙌🏾😀👍🏾

Local Expertise
Exterior Projects in Oakland, California
Oakland has over 150,000 housing units, with roughly 60% of homes built before 1960. Many older neighborhoods like Rockridge, Temescal, and Montclair have original roofing that is past its expected 25-30 year lifespan.
Oakland requires building permits for roof replacements. Permit fees typically range from $200 to $600 depending on project valuation. The City of Oakland Building Bureau processes most residential roofing permits within 5-10 business days.
Oakland receives approximately 23 inches of rain annually, concentrated between November and March. The mild Mediterranean climate is ideal for asphalt shingles, though hillside homes in the Oakland Hills should consider Class A fire-rated materials per California WUI zone requirements.
Oakland Hills neighborhoods above Highway 13 are designated WUI fire zones requiring Class A fire-rated roofing materials. The 1991 Oakland Hills firestorm led to some of the strictest fire-safety building codes in the East Bay.

Local Tip
Oakland's flat-fee permit structure makes it one of the most affordable cities in the East Bay for roofing permit costs. The city also allows over-the-counter permits for simple re-roofs with no structural changes.
