Serving San Diego County since 2013
A roof that lasts, built by people who show up.
Andler Building Co. is a licensed general contractor specializing in cool roof systems, tile lift-and-lay, and energy-efficient remodeling. One crew, one point of contact, from the first inspection to the final walkthrough.
Green building, done to a standard you can see.
We are a residential and commercial contractor based in Ramona, working across San Diego County. Most of our work starts on a roof: a leak, a cracked tile, or a system that has quietly stopped doing its job.
What sets the work apart is what goes underneath. Cool roof materials, proper underlayment, and energy-efficient detailing that lowers what the house costs to run — not just what it looks like from the street.
Every project begins with an in-person inspection and a written scope. No pressure, no guessing, and no surprise line items halfway through.
What we build
Full-service licensed contracting, with roofing as the backbone of the business.
Roofing & cool roof systems
Repairs, full tear-off and re-roof, and tile lift-and-lay. We work in tile, composition shingle and flat systems, and we specify cool roof materials that cut attic heat through a San Diego summer.
Energy-efficient windows
Simonton window replacement that seals properly and shows up on the utility bill.
Kitchen & bath remodeling
Full renovations handled in-house, from demo through final finish work.
ADUs & tiny homes
Permitted accessory dwelling units designed for rental income or family.
Solar & energy upgrades
Solar paired with roofing so the system goes on a deck that will outlive it.
Decks, patios & hardscape
Outdoor living built to handle the sun instead of fading under it.
Office & commercial
Tenant improvements and commercial remodels scheduled around your hours.
