Cambridge Pavers Roofing: The San Antonio Owner’s Guide
Most Cambridge Pavers roofing failures in San Antonio come down to one thing: the underlayment and flashing system beneath the pavers, not the pavers themselves. We stock Cambridge-compatible roofing components and install them for a typical range of $400 – $1,800 depending on the extent of the failure. Homeowners usually discover the problem after the first hard rain following a dry spell, when a ceiling stain or drip shows up in a corner of the house that’s been bone-dry for years.
What surprises most people is that the Cambridge paver itself is rarely the culprit. By the time water gets inside your home, the waterproofing layer underneath has been compromised, often for months. In San Antonio’s heat, sealants and underlayment materials break down faster than they would in cooler climates, and a paver roof that looked fine from the street can be quietly failing underneath. Here’s what you need to know about matching, pricing, and fixing it correctly.
Which Cambridge Pavers Models This Applies To
Cambridge Pavers manufactures interlocking concrete paving stones in several series lines, including the Maytrx, Ledgestone, and RoundTable collections. For roofing applications, the pavers are typically used as a cap or overlay on flat and low-slope roof decks, and the part that fails is almost never the paver itself. It’s the pedestal system, the paver support pads, or the waterproof membrane beneath.
The compatibility gotcha we see constantly in San Antonio: the pedestal height. Cambridge-compatible pedestal systems run from roughly 1/8 inch to 24 inches of adjustable height, and the correct height depends on the slope of your roof deck and the drainage plan. If a previous installer used the wrong pedestal range, water pools where it shouldn’t, and the membrane degrades years early. We match the pedestal to the deck, not to the paver, because that’s where the failure starts.
We install quality aftermarket pedestals and membranes that meet or exceed the OEM specifications for Cambridge paver systems. We’ll never tell you a part is “as good as OEM” without explaining exactly what that means for your roof: same load rating, same UV resistance, same drainage channel design. If your roof calls for original equipment, we’ll tell you that too. Our job is to give you an honest match, not a convenient one.
Styles & brands we work with
Signs Your Cambridge Pavers Roofing Is Failing
- Water staining on ceilings or walls after rain. This means water is getting past the membrane and traveling along the deck before it finds a path into your living space. The actual leak point may be several feet away from the stain.
- Pavers that rock or wobble when stepped on. A broken or collapsed pedestal underneath is shifting, which points to either improper installation or UV degradation of the support component. Once one pedestal fails, the pavers around it bear uneven load and start failing too.
- Visible gaps or separation between pavers. Cambridge pavers are designed with spacer tabs that keep consistent joints. When you see gaps widening or pavers drifting out of alignment, the system underneath is moving, not the pavers.
- Standing water that doesn’t drain within 24 hours. The pedestal system is designed to create a drainage plane. If water is ponding on the paver surface, the slope or the pedestal height is wrong, and the membrane underneath is now sitting in water every time it rains.
- Crumbling or cracked paver edges along roof penetrations. Around vents, drains, and parapet walls, improper cuts or missing edge restraints let pavers shift and chip. Those gaps let water in faster than anything else on the roof.

AfterReplacement Cost & What’s Included
Roof repair on a Cambridge paver system in San Antonio runs $400 – $1,800 for the typical repair: replacing failed pedestals, re-setting shifted pavers, and patching the membrane where it’s been compromised. Roof replacement, which includes new underlayment, new pedestals, and re-setting all existing pavers, typically falls between $8,000 and $20,000 depending on roof size and the condition of the existing pavers.
Every price we give you is a written line-item quote before any work starts. You’ll see the cost of materials, the labor, and any disposal fees listed separately. No verbal estimates that grow on the final bill, no surprise change orders. The work is covered by our written guarantee for 365 days from the completion date. If something fails within that year, we come back and make it right at no charge.
DIY or Call Us?
If you’re on a single-story roof with a gentle slope, you can safely inspect the paver surface yourself. Look for rocking pavers, wide gaps, and standing water. Those observations help us quote accurately over the phone. What you shouldn’t do is pull up pavers and start poking at the membrane underneath. If you puncture that membrane while you’re investigating, you’ve turned a $400 repair into a much bigger job, and you’ve likely voided whatever warranty remains on the system.
This is flat and low-slope roofing work. Falls from even a single-story edge can be life-changing, and a compromised roof deck can give way without warning. Isaac Pruett’s crew works San Antonio roofs the same way every time: fall protection, deck assessment before any weight is added, and no shortcuts on the waterproofing layer. If you’re not sure whether you should be walking on your roof at all, call us at (254) 269-5071 first.
FAQs
The pavers themselves can last 30 – 50 years, but the pedestal and membrane system underneath typically needs replacement every 15 – 20 years in San Antonio’s UV and heat conditions. Call (254) 269-5071 and we’ll assess the actual age and condition of your system.
Yes, in most cases a failed pedestal or a small membrane patch can be repaired for $400 – $1,800, and we’ll only recommend full roof replacement when the membrane has failed across a wide area. We’ll show you photos of what we find and explain why repair is or isn’t the right call before you spend a dollar.
Most pedestal replacements and membrane patches take one day. Full roof replacement typically runs three to five working days depending on roof size and weather, and we’ll give you a written schedule before the crew shows up.
Our trucks carry a range of standard pedestal heights and membrane materials so we can complete most repairs on the first visit. For non-standard pedestal heights or special-order paver matches, we’ll give you a firm timeline for ordering before we start, along with a written quote that won’t change when the parts arrive.
Know who’s coming, know what it costs, know it’s covered – that’s the whole job before the job starts. If you have a Cambridge Pavers roof that’s showing signs of trouble, call (254) 269-5071 to schedule your free estimate. A live person answers, and we’ll send a background-checked, uniformed technician with a name and photo you’ll receive before the visit.
