Cambridge Pavers Roofing: The San Francisco Owner’s Guide
We stock and install Cambridge Pavers-compatible roofing systems throughout San Francisco, with most roof replacements running $9,440 to $23,600 depending on square footage and substrate condition. If your Cambridge Pavers product has a failed paver, underlayment, or edge restraint, we can usually assess it within one business day and have the part matched quickly. Most owners discover the problem the same way: a paver shifts underfoot, a drip appears on the ceiling after a fog-heavy week, or a piece of flashing works loose near a parapet wall.
A note before we go further: Bradford Remodeling Co San Francisco is an independent service provider. We are not affiliated with Cambridge Pavers, but we work with their product lines regularly and know where the failure points live.
Which Cambridge Pavers Models This Applies To
Cambridge Pavers manufactures interlocking concrete paving stones in multiple series, and the roofing application typically involves their thinner-profile paver units set over a pedestal or proprietary underlayment system. The key compatibility check is the joint width and paver thickness. Cambridge roof-deck pavers generally run 1-3/4 to 2-3/8 inches thick, and that dimension matters because the pedestal and edge restraint have to match the unit’s height exactly. Put the wrong thickness on an existing pedestal grid and you’ll get lippage, rocking, or a void under the paver that invites cracking.
The easy way to identify what you have: flip over a loose paver. Cambridge molds their name and a plant code into the underside of most units. You’ll also see a production date stamp that tells us which run it came from. We match the part by measuring the paver face dimensions and thickness with a set of calipers on site, then cross-referencing the Cambridge catalog. For most San Francisco roof decks, the OEM paver is still the right call because the color blends are matched to the original installation. Aftermarket equivalents exist for some series, but we’ll tell you honestly if a substitute will look like a patch job.

Signs Your Cambridge Pavers Roofing Is Failing
- Rocking or shifting pavers underfoot. This usually means a pedestal has settled or the pedestal head has cracked. On San Francisco roof decks, wind-driven rain gets under a rocking paver and accelerates wear on the underlayment below.
- Water staining on the ceiling or soffit below the roof deck. By the time you see it inside, the underlayment has already been compromised for a while. Roof decks over living space fail quietly because the pavers hide what’s happening underneath.
- Efflorescence or white chalky residue on paver edges. That’s mineral salts coming to the surface as water moves through the paver. It’s not structural by itself, but it tells you water is traveling somewhere it shouldn’t.
- Loose or pulling edge restraints along the perimeter. The edge restraint keeps the whole field locked together. Once it starts to pull, the pavers begin drifting outward and the gaps widen.
- Cracked pavers near the drain or scupper. Freeze-thaw cycles are less of a factor in San Francisco than inland, but a cracked paver at a drain point usually means the pedestal system below has failed and the paver is taking point load it was never designed to carry.

AfterReplacement Cost & What’s Included
For Cambridge Pavers roof-deck work in San Francisco, replacement costs typically run $710 to $2,950 for targeted repairs such as single paver swaps, pedestal replacement, or edge restraint repair. A full roof replacement over a Cambridge Pavers assembly runs $9,440 to $23,600, depending on square footage, roof slope, access, and whether the substrate below the pavers needs work.
The range is driven by four things: the number of pavers being replaced, the condition of the pedestal system, the access situation (a fourth-floor roof deck with no elevator is a different labor picture than a second-floor deck with a wide stairwell), and whether the underlayment has to come up. We quote the parts line by line, and the labor separately, so you see exactly what you’re paying for. You get a written price before any work starts, with no numbers that move at the door. The work is covered by our 365-Day Done Right Promise: if the repair or replacement fails within a full year, we come back and correct it at no charge.

DIY or Call Us?
A homeowner can safely check a few things: look for visibly cracked or rocking pavers, inspect edge restraints for pull-away, and note any ceiling staining below the deck. What you shouldn’t do is start pulling pavers off a roof deck without knowing what’s under them. Roof decks over living space have waterproofing membranes, pedestal grids, and drainage layers that are easy to puncture. A slipped pry bar can turn a $900 paver replacement into a $6,000 membrane repair.
If the deck is low, flat, and clearly just pavers on sand or gravel with no living space below, a careful owner can lift and reset a single paver. If it’s elevated, over a room, or has pedestals, call us. Curtis Lane has spent two decades on San Francisco roof work, including enough Outer Sunset rebuilds to know exactly what fog moisture does to a roof assembly. We’ll give you a straight number on the repair and a written scope before any work begins. Call (831) 610-5598 and we’ll have a tech out to assess it.
FAQs
The concrete pavers themselves typically last 30 to 40 years, but the pedestal system and underlayment beneath them have a service life closer to 15 to 20 years in San Francisco’s coastal climate, where salt air and fog moisture accelerate wear on the hidden components. The pavers will almost always outlive what’s underneath them. Call (831) 610-5598 if your deck is past the 15-year mark and we’ll assess the assembly before a small underlayment issue becomes a ceiling stain.
For a hairline crack in a non-load-bearing area, a color-matched epoxy fill can buy you a few seasons, but for any paver that’s cracked through or sits at a drain point, replacement is the only repair that will hold. The failure is usually underneath the paver, not in the paver itself, so patching the surface doesn’t fix what caused the crack. We’ll give you an honest read on the paver and a written price either way.
A single-paver or pedestal replacement is usually a half-day job once parts are on hand. A partial field repair with underlayment work takes one to two days depending on weather and access. A full roof replacement over a Cambridge Pavers assembly runs five to ten working days, and we put that timeline in writing before the first paver comes up.
We stock the most common Cambridge roof-deck pavers and pedestal components, including edge restraints, shims, and replacement pedestal heads. For less common colors or discontinued runs, we order directly through our supplier network and can usually have the part matched and on site within a week. We also stock parts for KraftMaid, Cambria, and Silestone product lines for other areas of the home.
No. The written price you get before the job is the price you pay at close-out. If we open up the assembly and find something we couldn’t have seen from the surface, we’ll stop, show you what we found, and give you a written change order. Nothing gets done that you haven’t approved in writing. That’s The Garrison Standard, and it’s how every Bradford job is run from start to finish.
