Tremron Roofing: The San Francisco Owner’s Guide
Tremron roofing products, including concrete roof tiles and pavers used in roofing applications, are built to last decades in California’s climate, but flashing, underlayment, and specific tile profiles do fail over time. We stock Tremron-compatible replacement parts and can typically install them within a few days of your call. Installed pricing in San Francisco for Tremron roofing repairs runs $710 – $2,950, with full roof replacement at $9,440 – $23,600 depending on square footage and tile profile. Most owners discover a problem the same way: a ceiling stain after a heavy rain, a cracked tile spotted from the sidewalk, or granules collecting in a downspout after a windstorm off the Pacific.
Elmstead Remodeling San Francisco is an independent contractor, not affiliated with Tremron, but we have worked with their product lines across San Francisco long enough to know what fails first and what matches cleanly when it is time to fix it.
Which Tremron Models This Applies To
Tremron manufactures interlocking concrete pavers, retaining wall blocks, and concrete roof tiles under several product families, including their classic flat-profile roof tile and the heavier barrel-profile styles common on Spanish and Mediterranean homes in the Sunset District and the Richmond. The compatibility details matter: Tremron roof tiles are sized to a specific headlap and course spacing, meaning a tile from a different manufacturer may sit visibly proud or leave gaps at the eave. When we match a Tremron roof tile in San Francisco, we verify the profile height, the water channel depth, and the tile’s overall length before ordering anything.
Most Tremron tiles carry a manufacturer’s code stamped on the underside. If that is worn or painted over, we measure the exposed width and the side-lock geometry. For most San Francisco homes built or re-roofed between 1995 and 2015, we are matching a standard 13-inch-wide flat tile or a 9-inch barrel profile. We offer OEM Tremron parts when lead times allow, and quality aftermarket equivalents from regional California manufacturers for older profiles that Tremron has since discontinued. The aftermarket option often saves 20 – 30% with identical profile dimensions.

Signs Your Tremron Roofing Is Failing
- Water staining on ceilings after rain. This usually means the underlayment under the Tremron tiles has reached the end of its service life or a tile has cracked at the corner where it locks to the next course. By the time a ceiling stains in San Francisco’s wet winters, the failure has been developing for months.
- Visible cracks or spalling on individual tiles. Concrete tiles, including Tremron’s, can develop hairline cracks from foot traffic during chimney work or from thermal movement over decades. A cracked tile near a valley or penetration is a fast path for water to reach the decking.
- Granules or fine concrete dust in gutters. Tremron concrete tiles erode slowly in coastal air. Some granule loss is normal, but a consistent buildup in one downspout area points to a specific section failing faster than the rest of the roof.
- Flashing that is lifting or corroded. The flashing around chimneys, skylights, and vents is rarely Tremron – it is typically galvanized steel or aluminum from the original install. Coastal fog in the Outer Sunset accelerates corrosion on flashing long before the tiles themselves give out.
- Moss or lichen holding moisture at the tile edges. San Francisco’s fog belt keeps north-facing roof sections damp. Moss at the headlap can wick moisture under the tile and into the underlayment, shortening the roof assembly’s life even when the tiles still look sound.

AfterReplacement Cost & What’s Included
Tile roof repair in San Francisco runs $710 – $2,950 installed, covering the replacement tile or flashing, the underlayment patch, and sealing at the repair site. A full Tremron roof replacement on a typical San Francisco single-family home lands between $9,440 and $23,600, with the spread driven mostly by roof pitch, number of penetrations, and whether the existing underlayment can be reused. We use the same pricing framework across the company: a written price before any work starts, with every line item shown. That price stays fixed – no change order because a crew found something after tearing off the first section.
Every Tremron roofing repair or replacement we complete in San Francisco is covered under the 365-Day Done Right Promise. If the repair does not keep water out, we make it right at no additional cost. The photo of the completed clean-up is included with every job, and drop cloths and shoe covers are standard on every visit, not an add-on.
DIY or Call Us?
For a Tremron roof, there are a few things an owner can safely do from the ground: note which valley or penetration is staining, check gutters for tile grit, and photograph cracked tiles so we can estimate before sending a crew. What we would not recommend is walking a concrete tile roof without the right load distribution – Tremron tiles crack easily under a misplaced ladder or a kneel on the unsupported edge, and the roof loses more than the repair saves. Roof work on a tile system also means working at height with heavy materials, and a fall on a two-story San Francisco roof is not worth the risk.
If the tile is cracked, flashing is lifted, or water is getting in, call (831) 480-4497 for a free estimate. We will tell you what a repair costs versus a section replacement, and whether the underlayment is still worth saving.
FAQs
Tremron concrete roof tiles typically last 40 – 50 years in San Francisco, but the underlayment beneath them usually needs replacement between 20 and 30 years. Coastal fog, salt air, and the frequent wet-dry cycles in neighborhoods like the Outer Parks can wear underlayment faster than the tiles above it. Call (831) 480-4497 if your roof is over 20 years old and you are seeing interior stains.
A hairline crack in a single Tremron tile can sometimes be sealed with a concrete-compatible patching compound, but the repair rarely outlasts a full tile swap by more than a few years. We generally recommend replacing the cracked tile and the channel beside it – it is faster, and the fix is permanent. The exact cost depends on whether we can source a matching profile without waiting on a manufacturer order.
Most single-tile or flashing repairs on a Tremron roof take one half-day visit, assuming the replacement tile is on hand. Full section replacements and underlayment work typically run two to three days. We set quiet hours during the workday and protect the interior with drop cloths from the entry to the work area.
We keep common Tremron flat-profile and barrel-profile tiles on hand in neutral colors, along with the flashing profiles most San Francisco homes use. For specific color matches, discontinued profiles, or large replacement counts, we order direct from Tremron or our regional California suppliers, which typically adds three to seven days. Call (831) 480-4497 and we will tell you during the estimate whether we can match from the truck or need to order.
Tell me what the room needs to do, and we’ll figure out the rest from there. In the meantime, if your Tremron roof in San Francisco is leaking or showing its age, call (831) 480-4497 for a free estimate. We will write out every cost before any work starts and send a photo of the clean-up before the crew packs the truck.
