Boral Roof Replacement & Installation in Chicago: What to Know First
We provide independent Boral roof replacement and installation in Chicago, with most jobs completed in one to two days and pricing set before we start - no surprises on the invoice. A full Boral replacement on a typical Chicago single-family home runs between $8,500 and $16,000 depending on the series, roof pitch, and what we find underneath the old shingles. If you’re seeing cracked tiles, lifted edges, or water spots on your ceiling after a hard freeze, call us at (855) 641-3418 - a live person answers, day or night, and we’ll get a technician out to document what’s happening up there.
This page is for Chicago homeowners who chose Boral for its looks or its reputation and now need someone who knows how these specific products behave in our freeze-thaw climate. We’re not Boral, and we don’t pretend to be. We’re an independent Boral service provider that’s been climbing Chicago roofs since 1984.
How Boral Products Fail - and How We Fix Them
- Boral Saxony 900 Slate composite tiles develop hairline fractures along the locking flange after repeated Chicago freeze-thaw cycles. The tile itself is sound, but the flange takes the stress. We replace the damaged tiles with OEM Saxony 900s and upgrade the underlayment to a high-temp ice-and-water shield at the eaves, where wind-driven snow packs in behind the fascia.
- Boral Villa 900 concrete tile shows efflorescence that owners mistake for mold or water damage. It’s mineral bloom from the concrete substrate, harmless but unsightly, and it signals the tile’s surface seal is breaking down. We strip the affected courses, treat the substrate with a silane-siloxane penetrating sealer, and reset with matching Villa 900s - never pressure-wash, which drives water into the pores and accelerates spalling.
- Boral Cedarlite polymer shake curls at the butt edge in south-facing exposures where summer attic heat builds past 140°F. The polymer substrate relaxes and won’t return to profile. We replace curled shakes, add ridge venting to drop attic temperature, and use Boral’s color-matched touch-up kit on the new pieces so the repair doesn’t shout from the sidewalk.
- Boral Smog-Eating Tile loses its photocatalytic surface activity after about 8-10 years in Chicago’s heavy particulate environment - the titanium dioxide coating gets buried under road grime and soot. The tile still sheds water fine, but the air-purifying claim is spent. We document this for the homeowner, replace degraded tiles if the aesthetic bothers them, and note that no aftermarket coating restores the photocatalytic function.
- Boral flat concrete tile on low-slope applications (anything under 4:12 in Chicago) traps meltwater at the headlap during January thaws. Water finds a seam, freezes overnight, and pops the tile from the nail bed. We see this in Portage Park bungalows and Austin two-flats. The fix is removing the low-slope tile, installing a proper SBS-modified bitumen membrane, and switching to a standing-seam metal or Boral-approved high-profile tile with increased headlap.
Our Boral Roof Replacement & Installation Process
- 1
Photo inspection from the roof, not the driveway. Our technician walks every square foot, documents tile condition, flashing integrity, and deck deflection with dated photos you receive by email that evening.
- 2
Series identification and parts decision. We confirm your Boral line and color code. OEM Boral tiles are our first choice for visible courses; for discontinued colors, we source from Boral’s remaining inventory or match with a quality aftermarket equivalent, with your approval in writing.
- 3
Deck and underlayment assessment. We strip to the deck, check for rot at the eaves and valleys (common in Chicago homes with original soffit venting), and replace damaged sheathing. No tile goes back over compromised wood.
- 4
Installation to Boral’s fastening pattern, not guesswork. Each series has a specified nail count, placement, and overlap. Our crews follow it. Pete Callahan checks the first five courses personally on every Boral job - old habit from his Daley College training days.
- 5
Cleanup, final walk, and documentation. Magnetic sweep of the property, gutter rinse, and a written completion report with photos of the finished work. Your 90-Day Done Right Promise activates the moment we leave.
What Boral Roof Replacement & Installation Costs in Chicago
These are real numbers for Chicago’s market, based on jobs we’ve completed in neighborhoods from Beverly to Rogers Park:
- Boral tile repair (localized, under 50 sq. ft.): $450-$890
- Partial Boral replacement (one slope, valley to ridge): $3,200-$5,800
- Full Boral roof replacement, standard pitch: $8,500-$14,000
- Full Boral replacement with deck repair and upgraded underlayment: $12,000-$16,000
- New construction Boral installation: $9,500-$15,500 (varies with roof complexity)
What moves the price: roof pitch (steeper means more labor and staging), whether your Boral line is still in production, deck condition once we’re stripped to bare wood, and accessibility - tight Chicago lots with overhead power lines add time. The number on your estimate is the number on your invoice. Call (855) 641-3418 for a free, no-pressure estimate - we’ll come out, climb up, and tell you exactly what you’re looking at.
Why Chicago Homeowners Call Ridgeline Roofing Co. of Chicago for Boral Work
We’ve been on Chicago roofs since 1984. That’s not a credential we trot out - it’s the reason we know which Boral tiles failed in the ’98 ice storm and which held. Our 90-Day Done Right Promise means if something’s not right, we come back. No form to fill out, no manager to escalate to, no argument about whether it’s “within tolerance.” A roof doesn’t need to be impressive. It needs to hold.
Our technicians are background-checked, uniformed, and trained on Boral’s specific fastening and overlap requirements. If your Boral line has been discontinued, we also install GAF, Owens Corning, and CertainTeed - so we can recommend a true replacement, not just the one product we happen to stock. And when you call (855) 641-3418, a live person answers. Nights, weekends, the middle of a February blizzard. We’ve answered at 2 a.m. during a derecho. We’ll answer for you too.
FAQs
Will replacing my Boral roof void the manufacturer’s warranty?
No, provided the replacement is performed by a qualified roofing contractor following Boral’s published installation guidelines. As an independent Boral service provider, we install to those specifications and document our work with photos. If you have a remaining material warranty, we help you file the claim with Boral directly. Call (855) 641-3418 and we’ll review your warranty status during the estimate.
Can you still get parts for discontinued Boral tile lines?
Sometimes. Boral maintains limited inventory of discontinued colors and profiles at their regional distribution center. When OEM stock is exhausted, we source color-matched aftermarket equivalents from approved suppliers, or we can blend replacement tiles from less visible roof areas (dormer backs, behind chimneys) to minimize aesthetic mismatch. We’ll show you both options and the price difference before ordering anything.
Is it cheaper to repair my Boral roof or replace it?
Repair is cheaper in the short term, but not always the better spend. If you’re patching the third or fourth area of failure, or if the underlayment is past its service life, you’re throwing money at a roof that’s telling you it’s done. We give you an honest assessment of remaining useful life - no replacement pitch if a targeted repair will carry you five more years. For an exact answer on your roof, call (855) 641-3418 for a free inspection.
How fast can you complete a Boral roof replacement in Chicago?
Most full replacements take one to two days, weather permitting. We don’t strip a roof if rain is forecast within 12 hours - that’s how you get a soaked attic and a lawsuit. In spring and fall, we typically schedule within 7-10 days of estimate approval. Emergency tarping and temporary weatherproofing goes up same-day if you’re actively leaking. Call (855) 641-3418 to check current availability.
Do you offer a senior discount on Boral work?
Yes. We maintain a permanent 5% senior and veteran discount, applied to the total invoice after any other qualifying offer. No ID photocopies, no expiration dates, no paperwork runaround. Just mention it when you call (855) 641-3418 to schedule your estimate.
