Boral Roof Replacement & Installation in California: What to Know First

Our pricing is upfront - the number on the estimate matches the number on the invoice, with no surprises after the shingles come off.

Call (877) 367-1429 any time - a live person answers, even at 2 a.m. during a January storm.
How Boral Products Fail - and How We Fix Them
- Boral Saxony 900 Slate - The synthetic slate profile looks sharp on Pasadena craftsman homes, but we’ve seen accelerated UV embrittlement on south-facing slopes after 12-15 years in California’s high-sun index zones. The material gets chalky, then cracks at the fastening points. We replace with fresh Saxony 900 if the homeowner wants to stay with the line, or walk them through CertainTeed’s Grand Manor if they’re open to a heavier asphalt alternative that handles Pasadena’s heat cycles without the premium price tag.
- Boral Stone Coated Steel (Villa and Shake profiles) - The stone granule adhesion fails prematurely in coastal California’s salt-air corridors, especially from Ventura through Orange County. Granule loss exposes the galvanized steel to surface rust that isn’t structural yet but looks like catastrophe from the driveway. We strip to deck, treat any flash rust with an etching primer, and reinstall with OEM Boral fastening patterns - critical because the gauge and clip spacing differ from Decra or Metro’s specs, and mixing them voids whatever warranty period remains.
- Boral Concrete Tile (flat and low-profile S-tiles) - The classic failure we see in Riverside and San Bernardino counties is efflorescence bloom followed by freeze-thaw spalling, even though California’s freezes are mild. The real culprit is usually inadequate underlayment at original install; the tile itself is fine. We lift courses, install full ice-and-water shield at valleys and penetrations (California code now requires it in wildland-urban interface zones), and reset the original Boral tile where salvageable. If the color batch is discontinued, we source from Boral’s Arizona surplus warehouse - most homeowners don’t know that inventory exists.
- Boral Smog-Eating Tile - The titanium dioxide photocatalytic coating degrades unevenly, leaving mottled patches that alarm homeowners in Santa Monica and Berkeley who bought the environmental story. The tile’s structural integrity is usually intact; it’s a surface chemistry issue. We power-wash at low pressure with a pH-neutral solution that won’t strip remaining coating, then assess whether the aesthetic decline warrants full replacement or if selective course replacement with current-stock Smog-Eating Tile will blend acceptably after one season of weathering.
- Boral Metal Roofing (standing seam and modular panels) - Thermal expansion noise gets mistaken for structural failure, especially on the older 24-gauge residential runs from the early 2000s. The clips were undersized for California’s inland delta-T swings - 40-degree days, 60-degree nights in the Central Valley. We replace clip hardware with oversized sliding clips that accommodate movement without popping fasteners, or if the panel profile is too fatigued, we quote full replacement with current Boral gauge specs that addressed this in 2012.
Our Boral Roof Replacement & Installation Process
- 1
Call and schedule. A live person answers at (877) 367-1429, 24 hours a day. We book an inspection within 48 hours, sooner for active leaks.
- 2
Photo-documented inspection. Our background-checked, uniformed technician walks your actual roof - not a drone flyover, not a binocular assessment from the driveway. We photograph every failure point, every questionable flashing, every area where the Boral product is telling us what it’s made of.
- 3
Parts decision with full disclosure. We quote OEM Boral replacement components first, but if a line is discontinued or back-ordered past your tolerance, we present quality aftermarket alternatives that won’t compromise the remaining warranty or system integrity. You choose; we don’t substitute without written approval.
- 4
Installation by trained crews. Our journeymen know Boral fastening patterns, expansion clearances, and valley weave specifics. No apprentice works unsupervised on a Boral job - the tolerances are too tight and the callbacks too expensive.
- 5
Final walk and documentation. We test every penetration, photograph the completed work, and leave you with a written 90-Day Done Right Promise. If something’s not right, we come back. No paperwork to file, no argument, no runaround.
- 6
Cleanup and follow-up. Magnetic sweep of the grounds, disposal of all debris, and a check-in call at 30 days to confirm you’re satisfied. Most Boral replacements in California stay done - that’s the point.

A live person answers every call, 24/7, including the middle of a storm when you’re staring at a ceiling stain and wondering who to trust. We plan to be here in thirty years. The storm chasers won’t be.
FAQs
No - the original Boral material warranty expires on its own timeline regardless of who works on the roof, but improper installation by an untrained contractor can void whatever coverage remains. As an independent Boral service provider, we follow Boral’s published installation guidelines to preserve any valid warranty period, and we document our work with photos in case you ever need to file a claim. Call (877) 367-1429 if you’d like us to review your warranty status before we start.
Sometimes - Boral maintains surplus inventory at their Arizona distribution center for several discontinued colors and profiles, and we have relationships with salvage suppliers in California who stock overruns from large commercial jobs. When OEM isn’t available, we source quality aftermarket alternatives that match the critical dimensions and performance specs. We’ll tell you honestly what’s available before you commit to a repair or replacement.
Repair makes sense when the failure is isolated - one valley, a few wind-lifted tiles, a failed pipe boot - and the underlying underlayment is sound. Full replacement is the better investment when you’re seeing widespread granule loss, multiple leak points, or the underlayment has reached the end of its service life beneath the Boral surface material. We give you straight guidance either way; there’s no margin in replacing a roof that has five good years left. Call for a free inspection and we’ll show you exactly what we’re seeing.
Most full replacements take two to four days from tear-off to final inspection, weather permitting. Emergency repairs we often handle same-day. We don’t rush the drying time on underlayment or the proper seating of concrete tile - a roof doesn’t lie, and cutting corners shows up eventually. We’ll give you a realistic timeline when we quote, and we’ll be there when we say.
Yes - we maintain a permanent 5% discount for seniors and veterans, applied to the final invoice with no minimum job size. We also offer $50 off any repair over $250, a free second opinion on any written estimate you’ve received, and an $89 seasonal tune-up that catches small problems before they become expensive ones. That’s the full list - we don’t run rotating promotions or pressure tactics.
