Unilock Roofing: The Sacramento Owner’s Guide
Bradford Remodeling Co Sacramento installs Unilock-compatible roofing and roof edge systems across Sacramento, with most single-corner or small-section repairs running $400 – $1,800 and full roof replacements from $8,000 – $20,000 depending on substrate condition. We keep common Unilock coping and edge profiles on the truck, which means many small failures get addressed the same day we look at them. The way most Sacramento homeowners discover a Unilock roofing problem is a water stain on the ceiling after a long dry spell followed by a hard rain. The heat breaks down the sealant bond around the roof edge, and when the first storm hits, water finds the gap.
We also stock parts for KraftMaid, Cambria, and Silestone products, but this page is for the Unilock roofing owner who needs a straight answer on what failed, what it costs, and whether it’s a same-day fix.
Which Unilock Models This Applies To

Unilock’s roofing product line centers on concrete roof pavers and coping units used on flat and low-slope roofs, most commonly spec’d on mid-century modern homes and commercial-style residential builds throughout Sacramento’s older established neighborhoods like Land Park, East Sacramento, and Curtis Park. The three profiles we see most often are the standard 24″ x 24″ x 2″ roof paver, the 12″ x 24″ coping unit used at parapet walls, and the custom-radius bullnose coping on curved roof edges. Identification matters because the 2″ paver and the 2-3/8″ coping unit are not interchangeable, and mixing them creates a lip that holds water instead of shedding it.
We are an independent service provider and not affiliated with Unilock. That independence matters when it comes to the OEM-versus-aftermarket call. Unilock discontinued several roofing profiles that were common in Sacramento builds from the 1990s and early 2000s, so original units are sometimes only available as salvage. A quality aftermarket concrete paver from a Northern California precast yard often matches the dimensions, weight, and compressive strength of the original, and it costs 20 – 30% less than OEM. We’ll tell you which route makes sense for your specific roof line, and we’ll put that recommendation in writing before we order anything.
Styles & brands we work with







Signs Your Unilock Roofing Is Failing
- Water staining on interior ceilings near exterior walls. This usually means the sealant bond at the parapet or roof edge has failed, and water is traveling under the paver system. The leak you see is rarely directly under the failed paver.
- Loose or rocking coping units. Sacramento’s freeze-thaw cycles are mild, but the real culprit here is our 100-degree summer days. Repeated thermal expansion breaks the mortar bond between coping units and the substrate below.
- Efflorescence (white chalky residue) on paver surfaces. Water is moving through the concrete and depositing minerals on the surface. It’s not structural by itself, but it tells you the roof is holding moisture against the substrate.
- Cracked or spalled paver edges. Spalling happens when water trapped in the concrete freezes and expands, or when the paver was originally under-cured. A spalled corner is a trip hazard on an accessible roof and a water entry point on any roof.
- Membrane tears or lifted flashing at the transition points. On most Sacramento flat roofs, the membrane underneath the Unilock system is the real waterproofing layer. When the edge flashing lifts, water gets under the membrane and the pavers just make it harder to find the problem.

AfterReplacement Cost & What’s Included
In Sacramento, most Unilock roofing repairs fall between $400 and $1,800. That covers removal of the failed unit, inspection of the substrate and membrane beneath it, replacement of any damaged flashing, new mortar or sealant bed, and resetting the paver or coping unit. Full Unilock roof replacement on a typical Sacramento flat roof runs $8,000 – $20,000, and the spread comes down to three things: total square footage, whether the underlying membrane needs replacement, and whether the decking or insulation below the membrane has water damage. We give you a written price before any work starts, and that number does not move at the door. Every completed repair carries the 365-Day Done Right Promise: if the work fails within a year, we return and correct it at no charge.
DIY or Call Us?
An owner can safely do two things: document the symptoms (photos of the failed area, notes on when the leak appears) and keep foot traffic off a cracked or loose paver. What an owner should not do is lift a coping unit to look underneath. The paver system sits on top of the waterproofing membrane, and one wrong pry bar move turns a $600 flashing repair into a $4,000 membrane replacement. Roof edge work also means working at height, and a fall off a parapet wall is not how anyone wants to spend a Tuesday. If the paver is rocking, the substrate below it has already failed. That is a job for a crew that carries the right flashing, sealant, and replacement units on the truck. Call us at (279) 226-1509 and we’ll schedule a look.
FAQs

A properly installed Unilock concrete paver roof in Sacramento typically lasts 25 – 35 years before the pavers themselves need replacement, but the sealant and mortar joints need attention every 8 – 12 years because our summer heat cycles break down the bond faster than coastal climates. The membrane underneath usually dictates the real lifespan. Call (279) 226-1509 for an inspection and we’ll tell you what’s actually failing before we recommend replacing anything.
Small hairline cracks can sometimes be sealed with a concrete repair compound, but any crack wider than 1/16″ or any paver with multiple cracks should be replaced, because the crack is now a water path to the membrane below. We make that call based on what the paver is doing, not what’s cheapest. Call (279) 226-1509 and we’ll give you a written answer.
A single coping unit or paver replacement on a Sacramento roof typically takes 3 – 4 hours including substrate prep, flashing work, and mortar or sealant curing to a set point. We stage all work in writing before we start, so you’ll know the full timeline before the crew arrives. Call (279) 226-1509 to schedule a free estimate.
We keep common 24″ x 24″ x 2″ concrete pavers, 12″ x 24″ coping units, flashing rolls, and sealant on the truck for Sacramento service calls, which means many repairs happen the same day we inspect. Specialty profiles or custom-radius bullnose units are ordered from regional precast yards and typically arrive within a week. Call (279) 226-1509 and we’ll tell you over the phone whether your profile is a stock item.
