Flat Roof Repair Services in Berkeley, CA
Flat roofs fail differently than pitched roofs, and they get fixed differently too. A shingle roof mostly fails from the top down — wind, hail, sun damage on the exposed surface. A flat roof fails at its transitions: where the membrane meets a wall, a pipe, a piece of equipment, or a drain. That’s a different diagnostic problem, and it takes a different kind of repair.
This page covers every flat roof service we offer in Berkeley — from tracing an active leak to a full replacement, and everything in between. If you already know what’s wrong with your roof, pick the matching service below. If you don’t, that’s the normal starting point for most people who call us: a stain on the ceiling, a soft spot on the roof, water that only shows up when it rains hard. Start with leak detection or just call, and we’ll help you figure out which of these applies.
Every service below follows the same approach: diagnose first, explain what we found with photos, then repair — not the other way around. We work on residential flat roofs (additions, porches, garages), multifamily buildings near campus, and commercial properties in West Berkeley, using whatever material is already on your roof rather than defaulting to whatever’s easiest for us.

Frequently Asked Questions About Our Services
How do I know which service I need?
If you’re not sure, that’s completely normal — most flat roof problems aren’t obvious from the ground. Call us or start with our leak diagnostic tool, and we’ll point you in the right direction.
Do you handle both residential and commercial flat roofs?
Yes — from Craftsman additions in the flatlands to commercial buildings in West Berkeley, all serviced with the same diagnose-first approach.
Can one visit cover more than one of these issues?
Often, yes. A single inspection frequently uncovers more than one contributing issue — we address them together rather than requiring separate visits.
How much does flat roof repair cost in Berkeley?
It depends entirely on the cause and extent of the damage — see our cost guide for the real factors. We don’t quote a price without seeing the roof.
How fast can you respond to an active leak?
Emergency calls get priority scheduling, typically same-day. See our emergency repair page for what counts as urgent.
Do you offer a warranty on your repair work?
Yes — workmanship on every repair is warrantied against failure at the specific point we repaired. See our warranty terms for details.
Do I need a permit for the work I need done?
It depends on the scope. Most significant repairs and replacements need a permit from Berkeley’s Permit Service Center; some smaller repairs are exempt. See our permits page, and we’ll confirm during inspection.
