Boral Shingle Repair: The Jacksonville Owner’s Guide
Boral shingle repair in Jacksonville typically runs $425 to $1,150 installed, depending on how many shingles are damaged and whether the underlayment beneath them needs attention. We stock Boral-compatible repair materials on our trucks and can usually diagnose the failure and get the repair scheduled within a day or two of your call. Most homeowners discover the problem after a storm blows through, or when they spot granules collecting in gutters, or when a ceiling stain starts spreading in the upstairs bedroom.
Boral makes a premium composite shingle that holds up well in Florida, but no shingle is invincible against Jacksonville’s summer lightning storms and the pine limbs that come down with them. When a Boral shingle cracks, tears, or lifts, water gets under it. Once that happens in this climate, the damage underneath moves fast. We’re not being dramatic. We’ve pulled back Boral shingles in Mandarin and found decking that looked like a wet sponge three weeks after a single storm.
Which Boral Models This Applies To
Boral’s composite shingle lines include the Boral Cedar Shake and Boral Slate profiles, and both cross into repair territory in Jacksonville. The compatibility issue owners run into is color lot matching. Boral’s color runs vary slightly from year to year, the way any manufactured material does, so a shingle pulled from a new bundle will not always sit invisibly next to one installed six years ago. We flag that on every inspection: sometimes the honest answer is a smaller repair that looks close, and sometimes it’s a larger section replacement so the eye doesn’t catch a patch.
What you’re looking for on an original shingle is the Boral stamp on the underside, plus the profile geometry. Cedar Shake has a thicker butt edge and a staggered look. Slate sits flatter with a more uniform exposure. If you don’t have leftover bundles from the original install, we match by pulling a sample and measuring, then we order from Boral’s current stock. There’s a decision here between OEM Boral shingles and quality aftermarket composites, and we’re direct about it: for a Boral roof, we recommend staying with Boral. Substituting a different composite changes the look, sometimes the warranty picture, and almost always the resale curb appeal. We’re an independent roofing contractor, not affiliated with Boral, but we’ve installed and repaired enough of their product to tell you it’s worth matching correctly.
Styles & brands we work with






Signs Your Boral Shingle Repair Is Failing
- Granules in the gutter or at downspout bases. Composite shingles shed surface material as they age. A small amount is normal; a pile that looks like coarse sand after every rain means the shingle’s protective shell is breaking down faster than it should.
- A single shingle lifted at one corner. Jacksonville’s afternoon thunderstorms push wind in every direction. When one shingle is up and its neighbors are flat, the seal strip has failed and the shingle is loose enough to catch wind.
- Brown ceiling stains in the room directly under the roof. By the time you see the stain, water has already moved through the shingle, the underlayment, and the decking. This is not a caulk-and-paint fix.
- Shingle edges that look curled, cracked, or “smiling.” Composite shingles don’t curl as dramatically as old asphalt, but a Boral shingle that has lost its seal will cup at the corners. Once cupping starts, the shingle is done.
- Roof debris stacking up in one spot after a storm. Tree branches scrape across the roof, and pine needles pile against the roofline. Trapped debris holds water against the shingles, which accelerates failure. If one specific area always looks messy after wind, that’s where the repair starts.

AfterReplacement Cost & What’s Included
Here’s what Boral shingle repair costs in Jacksonville, based on the work we actually do:
- Single or small-area shingle repair (3 to 10 shingles): $425 to $675
- Section repair with underlayment (one roof plane, partial replacement): $700 to $1,150
- Flashing repair at chimney, wall, or pipe penetration (with shingle replacement around it): $550 to $900, depending on how much flashing has to come out
Those prices are installed: parts, labor, cleanup, and haul-off of any old material. What drives the range is access. A simple one-story walkable roof in Lakewood is faster than a steep two-story slope off San Jose Boulevard with landscaping that needs protection. Every repair starts with a written price in hand. Before any work starts, you get the number on paper. If the job is bigger than the first look suggested, we say so before we open anything up, and the price doesn’t move at the door.
Every Boral repair we do falls under the 365-Day Done Right Promise. That’s a written guarantee for one full year. If the repair fails within that period, we come back and make it right at no charge. We will also answer the phone when you call. No voicemail, no automated system. A live person picks up.
DIY or Call Us?
You can safely check a few things yourself: look for loose shingles from the ground with binoculars, check your gutter screens for the granule pile, and look at the ceiling after a heavy rain. Those checks are free and they tell you whether a repair is likely. What you should not do is get on a roof with a Boral patch in hand and a caulk gun. I’ll be straight about why: you’re on a sloped, possibly damp surface, and the repair you make from the top without checking the underlayment below is a repair that will fail when the next storm hits, except then you’ve also got the water damage that happened in the meantime. I grew up in Los Angeles and learned the trade at LATTC before spending nearly two decades working roofs up and down the Florida coast. We’ve run jobs across Jacksonville for years, from flat membrane work near Regency Square to full shingle tear-offs in Mandarin. The roofs here take a beating. The one thing I’ve seen ruin a good home is a small shingle problem ignored long enough to become a big decking problem. If it’s not right, we’re not done.
If you suspect your Boral shingles are failing, call us at (904) 719-6346. We’ll send a uniformed, background-checked technician to inspect it, and you’ll have the price in writing before any work starts.
FAQs
Boral composite shingles typically last 25 to 40 years in Jacksonville, but the actual lifespan depends on shade, roof pitch, and how often the roof gets hit by flying debris. A roof that sees full afternoon sun and regular tree-limb contact will age faster than a shaded roof with clean surroundings.
A cracked Boral shingle cannot be repaired; it has to be replaced. Once the shingle’s structure is compromised, sealant will not restore it, and the crack will keep letting water through. Call (904) 719-6346 if you need an exact assessment, and we’ll give you a written price.
Most small Boral shingle repairs take two to four hours, start to finish. Section repairs that require underlayment work can run a full day. We’ll tell you before we start how long your specific job will take.
We stock Boral-compatible repair materials and keep common profiles on hand for Jacksonville jobs. For uncommon color lots or larger section repairs, we order from Boral’s current production, and we’ll tell you the timeline before work starts. We also install GAF, Owens Corning, and CertainTeed materials, so if you’re considering a full replacement rather than another repair, we can walk you through options plainly.
