Concord's housing stock spans 5% pre-1950, 30% 1950-1969, 35% 1970-1989. Architectural styles range from 1960s-80s single-story ranch and split-level homes in Dana Estates to Holbrook. Each era and style presents different roofing requirements — from material compatibility to structural considerations. Our crews know what to expect before they arrive on site.
Concord has hot, dry summers with temperatures often reaching the upper 90s, combined with occasional winter rainstorms that test the durability of exterior systems. Composite shingles with high thermal resistance, such as GAF Timberline HDZ, perform well in these conditions while providing 130 MPH wind resistance for winter storms.
Concord offers one of Contra Costa County's most diverse housing stocks, from 1960s and 1970s tract homes to newer Crystyl Ranch developments, with median prices around $720,000. Many of these homes are approaching or have passed the 20-30 year mark for their original roofing, creating demand for replacement with modern materials that offer better energy efficiency and longevity.
The City of Concord Building Division handles permits through its Community Development Department, with standard residential projects processed in 4-6 weeks. Hamilton Exteriors (CSLB #1078806) handles all permit applications for Concord roofing projects, ensuring compliance with local building codes and California Title 24 energy requirements.

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 🌟 ✨ 💫🌟✨💫🌟✨💫☀️🙌🏾😀👍🏾

The team dis an excellent job on our roof. Carlos and his team are punctual, communicative and kept the worksite clean throughout the project. There was a slight delay in the beginning but the whole process felt smooth and stress free. Alex was generous enough to add in extra service worth $759. Highly recommended, honest roofing work.

They offered a reasonable price for my roof replacement, and overall I’m satisfied with the work. The main issue was that it took quite a while to finish because of the permit process. At one point, I was worried that the roofing materials left at the property might be stolen, so I texted them about it. They responded to my message right away, which I appreciated, and luckily nothing was stolen. Overall, the price was fair, they were responsive when I had concerns, and the project was completed.
