Tremron Roofing: The Riverside Owner’s Guide
Tremron roofing refers to concrete roof tile products manufactured by Tremron, a company known primarily for pavers and hardscape materials but with a line of roofing tiles that ended up on a fair number of Southern California homes in the 1990s and early 2000s. Roof repair and roof replacement involving Tremron tile in Riverside typically runs $400 – $1,800 for targeted repairs and $8,000 – $20,000 for a full roof replacement, depending on the size and pitch of your roof and whether we’re matching existing tile or starting fresh. Most Riverside homeowners discover a problem the same way: a tile cracked after a Santa Ana wind event, a leak showed up on the living room ceiling after a hard winter rain, or a tile simply slid out of place and now sits against the gutter looking like it’s waiting for a reason to fall.
We keep Tremron-compatible concrete tile profiles in stock at our Riverside yard, and we can usually match the color and profile of your existing roof within a couple of days. The honest part: Tremron stopped manufacturing certain tile profiles years ago, so a perfect color match isn’t always available. When that happens, we tell you before we order anything, and we show you swatches of the closest available options so you can make the call in daylight, not after we’ve already started.
A note up front: Penhallow Remodeling Riverside is an independent service provider and parts supplier. We’re not affiliated with Tremron, and we don’t claim to be a factory-authorized dealer. What we are is a local contractor that has handled enough Tremron tile roofs in Riverside, from the Arlington neighborhood to the hills above Canyon Crest, to know what holds up, what doesn’t, and what a fair price looks like.
Which Tremron Models This Applies To
Tremron produced concrete roof tile in several profiles, but the two most common lines we see on Riverside homes are the flat shake profile (often stamped with a wood-grain texture on the face) and the low-profile S-tile that mimics Spanish clay tile at a fraction of the weight. If your tile has a smooth underside and the installed thickness is between ½ inch and ¾ inch, you’re likely looking at Tremron concrete tile rather than clay. Clay tile is thinner at the nose but has a hollow, kiln-fired core that rings when you tap it with a knuckle. Concrete tile has a duller thud.
The compatibility gotcha: Tremron’s S-tile interlocking channels are slightly wider than most modern S-tile profiles. If you buy a generic S-tile from a big-box supplier and try to interlock it with Tremron, you’ll get a tile that sits proud of the row and leaves a gap where water can sneak under in a hard rain. We’ve seen this exact mistake on more than one Riverside roof. The fix is to source tiles that match the old Tremron channel width, not just the visible profile shape.
There’s no model number on the tile itself, which makes matching harder than it should be. We identify the profile by measuring the exposed width and the radius of the water channel, then matching against our inventory of reclaimed and new-old-stock Tremron tiles. On the OEM-versus-aftermarket question: for concrete tile in Riverside’s heat, an aftermarket tile from a reputable manufacturer (like Eagle Roofing Products or Westile) often outperforms the original Tremron tile simply because the newer concrete blends hold their color better under UV exposure. The original Tremron tiles fade noticeably after fifteen to twenty years of Riverside sun. We’ll talk through both options at the estimate, and the written quote will show exactly what you’d pay for either route.
We also handle parts and adjacent materials for KraftMaid cabinets, Cambria countertops, and Silestone surfaces when a roofing job reveals water damage on the interior, but the roofing scope itself stays focused on the tile, underlayment, flashing, and battens.
Styles & brands we work with
Signs Your Tremron Roofing Is Failing
- Hairline cracks running across the face of the tile. Riverside’s temperature swings, from near-freezing winter mornings to 105-degree summer afternoons, put concrete tile through a lot of expansion and contraction. A hairline crack starts at the tile’s weakest point, usually where the tile rests on the batten, and widens over a season or two. Once it cracks through, water gets under the tile and starts working on the underlayment.
- Tiles that have slid out of position or sit crooked in the row. The original battens on early-2000s Tremron roofs were sometimes plain pine, not pressure-treated. After twenty years of Riverside’s dry-wet cycles, those battens rot at the fastener points and the tile loses its grip. This is the most common failure we see on Tremron roofs in the Arlington and La Sierra areas.
- Granules or concrete dust collecting in the gutters. Concrete tile slowly erodes at the nose as UV breaks down the surface binder. A light dusting in the gutter is normal for a tile roof over a decade old. A heavy accumulation, plus soft tile edges, means the tile has passed its useful life and replacement is cheaper than chasing repairs one tile at a time.
- Water stains on the underside of the roof deck, visible from the attic. This tells you the tile itself is no longer the problem. The underlayment beneath the tile has failed. By the time you see staining inside, the repair has moved from “replace a few tiles” to “pull back the tile, replace the felt, and reset everything properly.” That’s a $1,200 – $1,800 job on a typical Riverside single-story, and it’s worth doing before the deck itself rots.
- Tile corners spalled off, exposing the lighter concrete core. Spalling is a Riverside-specific reality. Our hard water plus the sun’s UV breaks down the tile’s surface coat faster than in coastal cities. Once a tile spalls, it’s a moisture sponge. You’re not saving money by leaving it.

AfterReplacement Cost & What’s Included
For a targeted Tremron tile repair in Riverside, you’re looking at $400 – $1,800. The low end covers a handful of cracked or slid tiles, new battens where needed, and re-nailing the surrounding tiles that are still sound. The high end covers a larger section, underlayment replacement, and flashing work around a chimney or valley where the leak actually started.
A full roof replacement on a Riverside home with Tremron tile runs $8,000 – $20,000. What drives the number: roof square footage, whether it’s a single story (easier access, lower labor) or a two-story with a steep pitch (slower, more careful work), whether the existing underlayment can be salvaged or needs full replacement, and the tile you choose. New standard-profile concrete tile comes in under price. A premium shake profile or a heavier upgraded tile pushes you toward the higher end.
Every quote from us is a written number before we pick up a tool. That number includes the tile, new battens, fasteners, underlayment if needed, labor, haul-away of old material, and a written workmanship warranty. We don’t hand you a range and then charge more at the end. If we find hidden damage during the repair, we stop, show you the problem, and give you a written change before touching it. That’s the Kingswell standard, and Trevor Nash has run every Riverside job under it since we started here.
The workmanship warranty follows every tile we set: if the repair fails inside the guarantee period, we come back and make it right at no charge. No service call fee, no re-inspection fee. The only thing you pay for is if you decide to expand the scope while we’re already there.
DIY or Call Us?
Walking a Tremron tile roof in Riverside is not something we’d recommend a homeowner do themselves. Concrete tile is heavy but brittle. A tile that looks whole can crack under your foot, especially around the edges, and a broken tile means a fall hazard you didn’t have before. The pitch on many Riverside homes built in the 80s and 90s is steep enough that footing gets tricky fast. If you want to check your roof from the ground, use binoculars and look for the symptoms above. That’s the safe inspection.
Replacing one tile is deceptive. It looks simple: lift the tile, knock out the old nail, set a new tile, nail it in. But if the batten is rotted, the new nail won’t hold. If the underlayment under that tile is torn, you’ve sealed in a leak. If the replacement tile doesn’t match the Tremron channel width, you’ve created a new gap. We keep the right tile profiles, pressure-treated battens, and proper nails on the truck, and we’re on roofs in Riverside every week doing this exact repair. Call (341) 895-1170, tell us what you’re seeing, and we’ll send someone out to give you a written price before any work starts. If the job is small enough, we can often handle it the same day.
FAQs
Tremron concrete tile roofs in Riverside typically last 30 to 40 years on the tile itself, but the underlayment beneath the tile usually needs replacement around the 20-year mark. Riverside’s heat and UV exposure fade and weaken concrete tile faster than coastal climates, so we recommend an inspection around year 15 if you haven’t had one. Call (341) 895-1170 to schedule a roof inspection with a written condition report and price.
A cracked Tremron tile needs replacement, not repair. Concrete tile can’t be glued or patched in a way that holds up under Riverside’s weather, and any sealant you apply will fail within a season or two. The good news is a single tile replacement is a $400 – $600 job in most cases, not a major expense. Call (341) 895-1170 and we’ll match the replacement tile to your existing roof before we start.
A typical Tremron tile repair on a Riverside home takes two to four hours once we’re on site, and we can often schedule it within a couple of days of your call. Larger repairs involving underlayment replacement take a full day. Call (341) 895-1170 for a written estimate with a defined arrival window.
We keep the most common Tremron concrete tile profiles and colors in stock at our Riverside yard, including the flat shake and low-profile S-tile, so most repairs don’t wait on a supplier. For less common profiles or colors, we source new-old-stock or matching aftermarket tile within a few days and show you the match before any work begins. Call (341) 895-1170 and describe your tile; we’ll tell you over the phone whether we have it on the shelf.
