Boral Underlayment & Deck Repair Nationwide

Boral Underlayment & Deck Repair: The West Palm Beach Owner’s Guide

If your Boral roof system has underlayment or decking that’s failed, we stock Boral-compatible underlayment and can repair or replace damaged decking in West Palm Beach, typically at $95 – $165 per 100 square feet for underlayment replacement and $12 – $18 per square foot for deck repair, depending on access and how much sheathing has rotted. Most Boral underlayment and deck repairs are completed in one day, and we show up with the materials on the truck. The way most West Palm Beach homeowners discover the problem is a ceiling stain after a hard rain, or granules in the gutter that point to a roof that’s been holding water where it shouldn’t.

Which Boral Models This Applies To

Boral’s roofing lines don’t use a single universal underlayment spec. The two most common systems we work on in West Palm Beach are the Boral concrete tile profiles (Boral CST, including the flat and low-profile Mission and Slate lines) and the Boral steel systems, which use a different underlayment class altogether. Concrete tile calls for a minimum 30-pound ASTM D226 Type II felt or a high-temperature self-adhered membrane, because tile absorbs heat and holds it against the underlayment for hours. Steel roofs, which move more with temperature swings, typically pair with a synthetic underlayment rated for high-temperature contact and better tear resistance. If you’re trying to match what’s on your roof now, look at the tile or panel stamp on the underside, or check the original contract. The underlayment itself won’t have a Boral stamp on it. Boral specifies performance, not a single brand of felt, which is why the label matters less than the ASTM rating.

We use OEM-spec underlayment where Boral’s warranty is still active, and we’ll say so plainly when it isn’t. For older Boral roofs in West Palm Beach where the manufacturer warranty has run out, a quality aftermarket synthetic like the ones we source from GAF, Owens Corning, or CertainTeed often outperforms the original felt, especially with Florida’s humidity and afternoon downpours. We’ll show you the difference in dollars and in material before you decide.

Signs Your Boral Underlayment & Deck Repair Is Failing

• Damp spots on the ceiling after a normal rain, not a hurricane. This is the underlayment letting water through while the tile or metal above still looks fine. By the time the ceiling shows it, the decking below has usually been wet for a while.
• Tiles that have shifted or cracked after a storm, with dark patches visible underneath. Once the tile profile is broken, the underlayment is taking direct sun, rain, and foot traffic from the next tradesperson who walks the roof.
• Soft spots when you walk the roof near the eaves or valleys. That’s rotted decking, and in West Palm Beach it’s usually worse than it looks because the humidity keeps the wood damp long after the rain stops.
• Granules from the underlayment or tile surface collecting in gutters or at downspout outlets. Underlayment that’s breaking down washes fine particles through the roof system and into the gutter, which means it’s already well past its service life.
• Musty odor in the attic after rain, or insulation that’s clumping and darkening. Water that makes it past the decking doesn’t always reach the ceiling. In West Palm Beach attics, it often condenses or soaks into insulation first, which is where the smell starts.

Replacement Cost & What’s Included

We tell West Palm Beach homeowners to plan on $95 – $165 per 100 square feet for Boral underlayment replacement, installed. That includes removing the tile or metal in the affected area, pulling the old felt or membrane, and laying the new underlayment with the right fasteners and overlaps. Deck repair runs $12 – $18 per square foot when plywood or OSB has to be cut out and replaced. The spread comes down to roof pitch, how many tiles need to come off and go back on, and whether we’re working around skylights, valleys, or plumbing stacks that slow the job down and add flashing work.

What you get with us is a written line-item price before any work starts. Not a ballpark confirmed later. The number on the page is the number on the invoice, full stop. And the repair carries our 365-Day Done Right Promise: if it fails inside a year, we come back at no charge and make it right. That promise is in writing, not something our estimator said out loud.

DIY or Call Us?

There’s a limited list of things a homeowner can safely do here, and it ends at observation. You can check your gutters for granules, walk the attic with a flashlight after a rain, and note where any ceiling stains are. That tells you something’s wrong. What you should not do is pull Boral tile off a roof deck, especially in West Palm Beach where the tile is often brittle after years of sun. The tiles break under foot if you don’t know the load points, and a slipped tile on a two-story hip roof is a serious fall risk. Removing tile also exposes the underlayment to whatever storm rolls through while the job is half done. That’s how a $400 repair turns into a $4,000 deck replacement.

If you’ve got a failing Boral roof in West Palm Beach, call (728) 203-3066. We’ll come out, put eyes on it, and give you a written price before any tile comes off. You don’t pay for the estimate, and you don’t guess about what’s under there.
