Boral Roofing: The Pomona Owner’s Guide

Boral concrete and clay roof tile repair in Pomona typically runs $600-$2,500 installed, depending on whether we’re replacing individual tiles, underlayment sections, or addressing valley metal failure. We stock Boral-compatible tiles, fasteners, and flashings for the most common profiles found in Pomona’s 1960s-1990s housing stock, and most part-specific repairs are completed in a single visit. Most Pomona homeowners discover a Boral tile issue after a Santa Ana wind event loosens a corner, or when winter rain finds its way past cracked underlayment in the valleys where two roof planes meet.

Which Boral Models This Applies To

Boral’s U.S. tile lines fall into two families: concrete profiles (Saxony, Slate, and Villa) and fired clay (Catalina, Malibu, and Mission). The concrete tiles weigh roughly 820-1,100 pounds per square (a 10×10 foot roof area), while clay runs lighter at 600-900 pounds, so the structural load and fastener spec differ even when the visual profile looks identical. We match by the stamped code on the tile’s underside, usually a date-and-plant mark like “ONT-18” for Ontario, California production, plus a profile letter.

OEM Boral tiles are still manufactured in California and Texas, but for discontinued profiles, we source from Eagle Roofing Products or MCA, both of which maintain dimensional compatibility with Boral’s most common Pomona installations. The decision between OEM and quality aftermarket comes down to color fade matching. Boral’s concrete tiles carry a 50-year limited warranty on material, but that warranty is non-transferable and does not cover labor for replacement. We document which batch we’re installing so the homeowner has a record if a future claim arises.

Rowan Construction Group Pomona is an independent service provider with no affiliation with Boral Roofing. We source parts through our standard distributor network.

Signs Your Boral Roofing Is Failing

• Cracked or broken tiles at the rake edge or ridge. These are the wind-exposed zones on any Pomona roof, and the Santa Anas that funnel through the Pomona Valley gap between the San Gabriel and Chino Hills accelerate fatigue. One cracked tile becomes six when the next storm drives water into the underlayment gap.
• Water staining on ceiling drywall near valleys or penetrations. Boral tile roofs rely on 30-pound felt or synthetic underlayment as the true waterproof layer; the tile is the armor. When valley metal corrodes or underlayment dries out after 20-25 years, the stain is the last symptom, not the first.
• Granular debris in gutters that matches your tile color. Concrete tiles shed their color coat as they age. Heavy granule loss means the cement body is absorbing moisture, expanding, and contracting through Pomona’s 40-degree summer-to-winter temperature swings.
• Loose tiles that rattle or shift when walked. Boral tiles are hung on battens or direct-set with foam; either system degrades. Foam adhesive loses bond strength after 15-20 years in UV, and battens rot if the original installer used untreated lumber.
• Visible rust streaks from valley metal or flashing. Galvanized valley metal in pre-2000 Pomona installs was often 26-gauge or lighter. Once the zinc coating breaches, rust accelerates in the chlorine-heavy air that drifts inland from Los Angeles Basin smog.

Replacement Cost & What’s Included

The spread in each range reflects three variables: tile accessibility (steep pitches above 6:12 require scaffolding or roof jacks), whether we can color-match from stock or need to order, and what we find when we lift the surrounding tiles. Under Clause 1 of the Haven Standard, the written price we deliver before work starts is the price you pay. If we find rot in the sheathing, work stops until we’ve presented a signed change order with the revised scope and price. That’s the discipline that has kept our projects within a few percent of the original quote across 4,000-plus jobs since 2007.

Every Boral tile repair carries our 365-Day Done Right Promise and includes a documented photo record of the failed area, the repair, and the finished condition. You’ll have it before we leave the site.

DIY or Call Us?

Here’s where we draw the line. A homeowner can safely walk the perimeter with binoculars to spot cracked tiles, and can check the attic for fresh stains after rain. What you should not do: climb a Boral tile roof without knowing where to step. Concrete and clay tiles crack under point loads. Step on the wrong spot and you’ve turned a $600 repair into a $1,200 one, plus you’ve compromised the underlayment.

Tile removal requires a specific lifting motion to disengage the interlock without snapping the adjacent pieces. Valley metal replacement involves removing multiple courses, working around the waterproof membrane, and reinstalling with proper side lap. We’ve seen DIY attempts in Pomona’s Lincoln Park and north of the 10 freeway that started with three broken tiles and ended with a tarp and a call to us. Measure twice, then we can talk.

If you’re seeing any of the symptoms above, call (626) 606-1081. We’ll schedule a free estimate, deliver a written price with line-item scope, and if you have a competitor’s quote, we’ll review it line by line at no charge.
