Boral Roof Installation in Miami: What to Know First
Boral roof installation in Miami runs $14,000 to $42,000 on a typical single-family home, and most full tear-offs and replacements take 5 to 9 working days once permits clear. We’re an independent Boral service provider, which means we install and repair Boral concrete and clay tile roofs without being locked into any manufacturer’s sales script. If you own a Boral roof and you’re weighing repair against replacement, or you’ve got tile failures after a storm, call (850) 753-2996 and we’ll give you a straight answer and a written price before any work starts.
This page is for Miami homeowners who already have Boral tile, or who are considering it for a roof replacement, and want to know what actually happens on a Boral job from tear-off to final inspection. That includes what fails, what it costs, and how to avoid paying for work you don’t need. Grant Whitlock and our crew have put Boral roofs on everything from 1920s Coral Gables Spanish revivals to flat-top commercial buildings near Brickell, so we know the product’s strengths and its blind spots.
Key Takeaways
- Typical Boral roof installation in Miami: $14,000 – $42,000 depending on roof size, pitch, decking condition, and tile profile.
- Boral failure is rarely the tile itself. It’s usually underlayment, flashing, or attachment points that give out first.
- We’re independent. We install Boral correctly, but we’re not a Boral dealer and we don’t answer to their warranty department.
- Every job gets a written price first. No work starts until you’ve seen the number and signed off on it.
- 365-Day Done Right Promise. If it’s not right within a year, we come back and make it right, in writing.

How Boral Products Fail – and How We Fix Them
Boral makes a genuinely strong tile. But in Miami, the tile is rarely the first thing to go. It’s what’s underneath it, and what’s holding it on. Here are the five failure patterns we see most on Boral roofs in Miami, and what we do about each one.
- Underlayment breakdown on Boral CedarLite and Barcelona profiles. Boral tile can last 50 years; the underlayment underneath usually lasts 15 to 20 in Miami’s heat and humidity. When the underlayment degrades, water gets to the decking and you’ll see ceiling stains near exterior walls before you ever see a cracked tile. Fix: full underlayment replacement with a high-temp synthetic or double-layer system rated for Miami’s UV load, then re-lay the existing tile if it’s still sound.
- Nail fatigue and lifted tile on Boral VillaTile and Saxony. These heavier profiles put real stress on fasteners. After a few hurricane seasons, we see tile that looks fine from the ground but is actually hanging on by rusted nails or shifted battens. The tell: small tiles out of alignment near hips and ridges. Fix: remove, inspect, and re-secure with new corrosion-resistant fasteners, not just renail over the old ones.
- Flashing failures around Miami chimney and skylight transitions on all Boral profiles. Flashing is the #1 leak point on any tiled roof in Miami, and Boral’s dense profiles make sloppy flashing work show up faster. Fix: custom-bent flashing replaced at every penetration, with proper weep screeds, so water exits instead of pooling.
- Cracked or spalled Boral tile after impact or salt exposure. Homes within a few blocks of Biscayne Bay get salt spray that accelerates surface wear on Boral tile. We also see cracked tile from wind-driven debris after tropical storms. Fix: replace damaged tile with matching profile and color where possible. If the line is discontinued, we source compatible aftermarket tile that matches in profile and weight, and we tell you exactly what we’re using and why.
- Attachment-point failure on Boral flat-to-wall transitions common in Miami mid-century builds. Many Miami homes built from the 1950s to the 1970s have low-slope sections that meet vertical walls. Water pools there, and the Boral transition pieces loosen over time. Fix: re-detail the transition with new flashing and proper mortar or mechanical fastening, depending on profile.
One thing worth knowing: Boral’s own warranty covers manufacturing defects in the tile, not installation or underlayment. So if your Boral tile is cracked, don’t assume the warranty check is in the mail. Let us look first. We’ll tell you what’s actually failing before you make an expensive decision.
Our Boral Roof Installation Process
Every Boral job follows the same sequence, whether it’s a full tear-off or a repair on one section. Here’s what to expect from the first call to the last inspection:
- 1
Call and talk to a live person. You get a real human on the phone 24/7, not a voicemail tree. Tell us what you’re seeing: leaks, cracked tile, tiles on the ground after a storm. We’ll schedule a visit.
- 2
Walk the roof with you. Grant or one of our techs walks the entire roof, not just the problem area. We look at decking from the attic, check underlayment condition, and map every flashing point. You’re welcome to watch or stay inside. Before anyone arrives, you’ll get the technician’s name and photo sent to you, and they’ll present a photo ID at your door.
- 3
Written price, line by line. We give you a written price with every line item spelled out. If we find hidden damage during the job, we stop and show you before we proceed. No change orders without your signature.
- 4
Tear-off and prep. We remove old tile and underlayment, inspect decking, and replace any rotted or soft wood. We don’t tile over a bad deck. That would be cheap, not good.
- 5
Installation. New underlayment, new flashing, then Boral tile laid to the manufacturer’s installation spec and Miami-Dade code. We use corrosion-resistant fasteners rated for coastal air.
- 6
Test and walk through. We water-test vulnerable points, walk you through everything we did, and leave you with your written guarantee. If anything fails within 365 days, we return and make it right. That’s the Done Right Promise, in writing.

AfterWhat Boral Roof Installation Costs in Miami
Here are the honest numbers, based on what we’ve quoted on Miami Boral jobs in the last few years. These are installed prices including labor, materials, underlayment, flashing, and debris removal.
| Boral Scenario | Typical Miami Price Range | What Drives the Price |
|---|---|---|
| Full Boral tile roof replacement, 1,500 sq ft home | $16,000 – $28,000 | Decking condition, roof pitch, tile profile |
| Full Boral tile roof replacement, 3,000+ sq ft home | $30,000 – $45,000 | Roof complexity, number of valleys and hips, accessibility |
| Underlayment replacement only (tile re-laid) | $7,000 – $14,000 | Tile condition, roof size, how much tile can be reused |
| Tile repair or replacement (small section) | $600 – $2,500 | Number of tiles, access difficulty, whether flashing is involved |
| Flashing replacement at chimney or skylight | $800 – $2,200 per penetration | Flashing material, roof access, whether tile must be lifted |
The biggest variable is decking. We won’t know what’s under the tile until we lift it, and that’s exactly why we never give a final number over the phone. We give you a written price after we walk the roof. Call (850) 753-2996 to schedule your free estimate.
Why Miami Homeowners Call Mercer Roofing Co Miami for Boral Work
Plenty of roofers in Miami will say they can install Boral. What they won’t tell you is who’s actually showing up at your door.

They arrive in a clean, marked uniform and present a photo ID at your door. That’s the badge-at-the-door promise, and it’s not optional on any job we do. It’s part of how each independently owned location operates under the Threshold Group quality framework.
We also install and repair GAF, Owens Corning, and CertainTeed, so if we’re on your Boral roof and we spot an issue that would be better solved with a different underlayment or flashing approach, we’ll tell you.

FAQs
Yes, major Boral lines like CedarLite, Barcelona, VillaTile, and Saxony are available through South Florida distributors, and we can source them for full replacements or repairs. If your specific tile has been discontinued, we’ll find a compatible aftermarket tile and tell you exactly what it is before we install it.
Boral’s warranty covers manufacturing defects in the tile, not the underlayment, flashing, or installation workmanship. Our installation is covered by our written guarantee and the 365-Day Done Right Promise, which is separate from Boral’s warranty. We’ll explain what’s covered by whom before any work starts.
Many Miami Boral roofs fail at the underlayment layer years before the tile itself wears out, so you can often keep the existing tile and replace only what’s underneath. We won’t know for sure until we lift a test section, but we’ll show you the condition of your tile and decking and give you a straight answer. Call (850) 753-2996 to schedule a free estimate.
Most full Boral replacements take 5 to 9 working days after permits clear, depending on roof size and weather. Miami afternoon thunderstorms can stretch a job by a day or two, but we’ll give you a realistic timeline in writing after the initial walk.
We can absolutely repair small sections. If the cracking is isolated to a few tiles and the underlayment below is still sound, we’ll replace only what’s damaged. If we see a pattern that suggests wider underlayment failure, we’ll tell you before recommending anything bigger. Our free second visit applies if a repair fails, so you’re not gambling on a patch job.
