Boral Roof Replacement in Santa Clarita: What to Know First
We replace Boral roofing systems across Santa Clarita as an independent Boral service provider, and most full replacements take 2 to 5 working days once materials land. Boral tile and Boral steel are both long-wearing, but when the underlayment beneath them fails or the fasteners have had enough, a full replacement is the only honest fix, and we’ll tell you that straight. Before you call, know this: we put a written price in your hand before any work starts, and that number does not move. Call (661) 219-7793 to schedule a free estimate.
This page is for Santa Clarita homeowners who own a Boral roof and need to know what replacement actually involves: why Boral systems fail the way they do in this specific climate, what the job should cost, and how we run a replacement so you’re never guessing. If you’re just starting your research, the key takeaways below will save you an hour.
Key Takeaways
- Boral tile and Boral steel usually outlast their underlayment; in Santa Clarita, the underlayment is the first thing to go, not the tile.
- Full Boral replacement in Santa Clarita typically runs $14 to $28 per square foot installed, depending on profile and decking condition.
- We are not affiliated with or authorized by Boral, but we install their systems to manufacturer spec so any applicable material warranty stays intact.
- Every Boral replacement we do includes a written price before work starts and the 365-Day Done Right Promise on the labor.
How Boral Products Fail – and How We Fix Them
Boral makes a genuinely good roof. But no roof is permanent, and in Santa Clarita the failure modes are predictable. Here is what we see on Boral jobs across Valencia, Saugus, Canyon Country, and Newhall, and what we do about it.
- Underlayment breakdown under Boral concrete tile. This is the big one. The tile itself can last 50 years, but the felt or synthetic underlayment beneath it is typically rated for 20 to 30, and Santa Clarita’s dry heat plus UV exposure accelerates that clock. We pull the tile, strip the old underlayment to the deck, inspect every sheet of decking, and lay new synthetic underlayment before resetting or replacing tile. The tile looks the same from the street; the roof actually works again.
- Boral S-Tile (the classic Mission profile) cracking at the hips and ridges. S-Tile is Boral’s most common profile in Santa Clarita residential work. The hips and ridges take the most direct sun and the most thermal stress. When those tiles crack, water gets to the fasteners and the underlayment. On a replacement, we replace the entire hip and ridge system with new Boral-compatible pieces and new flashing, not just the cracked tiles, because patching a failing hip is how you buy yourself six months instead of twenty years.
- Fastener fatigue on Boral steel roofs installed before 2010. Older Boral steel panels were sometimes installed with fasteners that didn’t have the neoprene washers we use now. In the Santa Clarita summer, panels expand and contract daily, and those fasteners back out or weep rust. If your steel roof is 15 to 20 years old and you’re seeing rust trails or loose panels, we’ll replace the whole panel system rather than chase individual fasteners, because the failure is systemic.
- Valley flashing failure on Boral tile roofs. Valleys are where two roof planes meet, and they channel more water than anywhere else on the roof. On older Boral tile installs, the valley metal was often undersized or the wrong gauge. We see this constantly in Stevenson Ranch, where the lot grading and roof lines create long valley runs. During a full replacement, we install new 28-gauge minimum valley flashing, wider than what was there originally, with a closed-valley tile layout that actually sheds water.
- Decking rot at the eaves under Boral tile. Concrete and clay tile are heavy, and when gutters clog in the fall, water backs up under the eave edge and rots the OSB or plywood. In Newhall and Canyon Country, where mature trees drop leaves and needles onto Boral roofs, this is a recurring problem. On a full Boral replacement, we replace every rotted decking board, not just the visible sections, because the rot is always bigger than the water stain.

Our Boral Roof Replacement Process
Here’s how a Boral replacement goes when you call Crestview Roofing Co Santa Clarita, from first call to final walkthrough.
- 1
Call and schedule. A live person answers. You’ll get a set arrival window, and you can track the tech’s arrival time live, through The Relay Standard, so you know exactly who is pulling up and when.
- 2
On-site diagnostic. We walk the roof, document the failing areas with photos, and check the decking condition from the attic where accessible. If it’s a Boral tile system, we check the underlayment exposure at the eaves and valleys, because that tells us more than the tile ever will.
- 3
Written estimate. Before any work starts, we hand you a written price, line by line: tile or steel, underlayment, flashing, decking replacement, haul-off, and permit. The number on the page is the number on the invoice. No change orders unless you ask for something extra.
- 4
Replacement. We tear off the old system down to the deck, replace any compromised decking, install new synthetic underlayment and flashing, and set the new Boral material to manufacturer spec. We photograph before, during, and after, and send you the photos by text so you can see the work even if you’re at the office.
- 5
Inspection and cleanup. We run water testing on valleys and penetrations, magnet-sweep the property for nails and fasteners, and walk you through the finished roof. You get a digital invoice by text and the 365-Day Done Right Promise in writing, included on every replacement.

AfterWhat Boral Roof Replacement Costs in Santa Clarita
Here are straight numbers. These are installed ranges for full Boral replacement in Santa Clarita, including tear-off, haul-off, underlayment, flashing, and standard decking repair.
| Boral System | Typical Installed Range (per sq ft) | Notes |
|---|---|---|
| Boral S-Tile (Mission profile) | $14 – $19 | Most common; heavy, requires decking verification |
| Boral Flat Tile (low profile) | $15 – $21 | Less weight, modern look; more fasteners per tile |
| Boral Steel (standing seam or corrugated) | $16 – $24 | Higher material cost, lower labor hours |
| Decking replacement (if rotted) | $2 – $4 | Per sq ft of decking actually replaced |
What moves the price: roof pitch (steeper is slower), the amount of decking rot, horseshoe runs and valley count, and whether you’re replacing tile with tile or switching from tile to steel. A two-story Stevenson Ranch tile job will run higher than a single-story Valencia rancher. Call (661) 219-7793 for an exact quote on your roof. Estimates are free, and the price is in writing before anything starts.
Why Santa Clarita Homeowners Call Crestview Roofing Co Santa Clarita for Boral Work
Boral is a specific system, and it deserves a crew that treats it that way. We’re not a crew that shows up, guesses, and invoices at the end. Dylan Pace grew up in Los Angeles and learned the roofing trade through the construction technology program at Los Angeles Trade-Technical College, and he has been putting roofs on Santa Clarita homes for years, including plenty of Boral tile jobs up in Stevenson Ranch where the summer heat tests every shingle and every seam. Every estimate we hand you is one we’d be comfortable signing twice.
We back every Boral replacement with the 365-Day Done Right Promise: if a covered item fails within 365 days, we fix it at no charge, including a free second visit. Our techs are background-checked and uniformed. And because we also install GAF, Owens Corning, and CertainTeed systems, we’ll never push you into a Boral replacement if another material fits your house and budget better. The goal is the right roof, not the biggest invoice.
FAQs
No, if the replacement is done to Boral’s installation spec, the applicable material warranty remains intact. We install Boral tile and steel systems to manufacturer specification as an independent Boral service provider, and we document the install so you have the records if you ever file a claim. Call (661) 219-7793 and we’ll walk through what your specific product line covers.
Most Boral replacements in Santa Clarita take 2 to 5 working days from tear-off to final inspection, depending on roof size, pitch, and decking condition. Weather delays are rare here, which is one advantage of roofing in this climate. We’ll give you a written schedule with the estimate, and the crew shows up on time, every day, until the roof is done.
Both are valid, and it depends on your house and your timeline. Boral steel is lighter, faster to install, and reflects more heat in Santa Clarita summers, which can reduce your cooling load. Boral tile lasts longer and holds its look, but it’s heavier and the decking has to be verified for the load. We’ll price both options in writing and recommend the one that fits your structure and budget, no upselling.
In Santa Clarita, full Boral replacement runs roughly $14 to $28 per square foot installed, with Boral steel at the higher end and S-Tile in the middle. Square footage, decking rot, valley count, and roof pitch are the real drivers. Call (661) 219-7793 for a free written estimate, and you’ll know your exact number before anything starts.
Sometimes, yes. If the tile or steel panels are in good shape and the failure is limited to flashing, a valley, or a small section of underlayment, we’ll tell you that and give you a repair price. If the underlayment has reached the end of its life or the fasteners are failing across the roof, a repair becomes a patch, and we’ll recommend replacement in writing. We’re not going to sell you a roof you don’t need.
