Unilock Roofing: The Boca Raton Owner’s Guide
Unilock roofing systems in Boca Raton typically run $400-$1,800 for component-level repairs and $8,000-$20,000 for full replacement, with most Unilock-compatible flashing, membrane, and drainage parts available same-day through our supply chain. We stock the common failure points - ridge vents, step flashing, and underlayment transitions - for the Unilock roof systems we see most often in Palm Beach County. Most Boca Raton owners discover a problem during our heavy summer rains, when water shows up at a ceiling corner or a tile lifts in the wind.
Which Unilock Models This Applies To
Unilock’s roofing line is narrower than their paver catalog, which is what most homeowners know them for. The Unilock roof systems we’ve worked on in Boca Raton fall into two groups: the older membrane-and-tile systems installed from roughly 2008 to 2016, and the more recent integrated drainage profiles used in select custom builds near Mizner Park and Royal Palm Yacht & Country Club.
To identify your system, check the ridge cap for a stamped Unilock logo or look for a specification sheet in your closing documents. The critical compatibility point is the membrane thickness - Unilock’s spec runs 60-mil TPO on most residential jobs, but we’ve encountered 45-mil retrofits where a previous contractor substituted material. The step flashing profile also varies by series; the pre-2016 systems used a 4-inch exposure, while current spec calls for 5-inch. We source OEM Unilock membrane where the project warrants it, but we also carry Carlisle and Firestone equivalents that meet the same 60-mil, heat-welded spec at lower cost. The decision depends on whether your warranty is still active and what the manufacturer will honor.
Signs Your Unilock Roofing Is Failing

- Water staining at interior ceiling corners. This usually traces to failed step flashing where the roof meets a vertical wall. In Boca Raton’s salt-air environment, the galvanized coating on older flashing degrades faster than inland specs predict, and the Unilock membrane can’t compensate once the metal is compromised.
- Lifted or cracked tiles after a storm. The interlock profile on Unilock tiles depends on a flexible membrane beneath; when that membrane shrinks or delaminates, tiles lose their seat and wind gets underneath. We’ve seen this accelerate after the third summer of thermal cycling.
- Standing water 48 hours after rain. Unilock systems rely on a tapered insulation layer for drainage. When that substrate settles or the drains clog with palm debris common to Boca Raton lots, water ponds and begins breaking down the membrane at the low point.
- Musty odor in attic or top-floor rooms. This indicates vapor drive through a compromised vapor barrier, often at a membrane seam that opened because the heat-weld failed. Florida’s humidity makes this worse - the gap doesn’t need to be large to move significant moisture.
- Visible granule loss or alligatoring on membrane seams. The TPO surface breaks down under UV exposure; Boca Raton’s latitude delivers more annual sun hours than northern markets, and we’ve observed 12- to 15-year actual lifespan on membranes rated for 20 years in milder climates.

AfterReplacement Cost & What’s Included
For Unilock roofing in Boca Raton, repair work runs $400-$1,800 depending on how much membrane we open, whether the substrate is sound, and whether we’re matching existing tile color. Full replacement on a typical 2,000-square-foot home falls in our standard $8,000-$20,000 roof replacement range, with Unilock-compatible systems landing mid-range because of the specialized flashing and membrane welding equipment.
Every quote we write itemizes parts and labor separately - membrane by the square, flashing by the linear foot, and disposal as its own line. Under Clause 1 of the Haven Standard, that written price is fixed before work starts; no change proceeds without a signed change order. Our 365-Day Done Right Promise covers the installation, and the membrane itself carries the manufacturer’s warranty when we source OEM or approved equivalent. You’ll receive a documented photo record of the substrate condition, the new material install, and the finished work before we request final payment.
DIY or Call Us?

A homeowner can safely check the obvious: cleared drains, visible debris on the roof, and whether a ceiling stain is growing after rain. Do not climb on a tile roof - the tiles crack under point load, and the slope combined with Boca Raton’s afternoon thunderstorms creates a real fall hazard.
Membrane work is not a DIY project. TPO requires a heat welder running at 600-plus degrees, and the seam must pass a probe test to hold warranty. We’ve been called to three jobs in the past two years where a homeowner’s self-installed patch failed within months, doubling the final cost because we had to remove the incompatible material before starting fresh. If you’re seeing any of the symptoms above, call (754) 254-8065 and we’ll schedule a free estimate with a written price before any work starts.
FAQs
In Boca Raton’s climate, we’ve observed 12 to 18 years on Unilock-compatible TPO membrane systems, shorter than the 20-year rating assumes. The combination of UV exposure, salt air, and thermal cycling from 90-degree days to 60-degree winter nights accelerates seam stress. Call (754) 254-8065 for an exact quote - estimates are free.
Small punctures or isolated seam failures can be heat-welded if the surrounding membrane is still supple, which we verify with a bend test. If the membrane cracks when flexed, patch welding will fail within a season. We document this test with photos so you can see the condition yourself. Call (754) 254-8065 for an exact quote - estimates are free.
Most residential replacements we handle in Boca Raton run three to five working days, assuming no substrate replacement is needed. If the tapered insulation is waterlogged, add two days for removal and re-sloping. We schedule each phase with a signed completion checkpoint before the next crew arrives. Call (754) 254-8065 for an exact quote - estimates are free.
We stock the common failure components - 60-mil TPO membrane, step flashing in 4-inch and 5-inch exposures, ridge vents, and compatible sealants - and can source OEM Unilock material within 48 hours for warranty-sensitive jobs. Our supplier relationship covers fifty-plus vetted brands, including the full roofing line. Call (754) 254-8065 for an exact quote - estimates are free.
