Why Mercer Roofing Is Kendall’s Preferred Roof Repair Company
Kendall homeowners deal with a specific set of roof problems, and we know them by name: cracked tile mortar from 160-degree summer surface heat, oxidized flat-roof membranes over rear additions, and post-Andrew tile roofs hitting the 25-to-30-year mark all at once. Most roofing companies can patch a leak. Few can tell you why your insurer flagged the underlayment before you even file a claim. That’s the difference our Roof Repair team brings to every Kendall job.
We also know that opening the door to a roofing technician is a real decision. Every Mercer technician is background-checked and identity-verified under the Threshold Verified standard. Before your appointment, you get the name and photo of the person coming to your door. When they arrive, they badge in with a photo ID. You’ll never wonder who’s on your property.
Founded in 2000, Mercer Roofing is part of the Threshold Group family of home-service companies. Each location is independently owned and operated, and every one is contractually held to the same standard: uniformed technicians, written pricing, and a written guarantee on every repair. Homeowners in Kendall call us because we solve the problem most roofers ignore. The stranger-at-the-door risk.

Metal Roof Repair in Kendall
Metal Roof Repair in Kendall typically runs $450 – $1,400 depending on whether we’re replacing a seam, repairing screws and gaskets, or rebuilding a transition where a metal panel meets a tile or flat section. Metal roofs aren’t the majority of Kendall’s housing stock, but plenty of carports, screened enclosures, and rear additions use standing seam or corrugated metal, and those sections fail in predictable ways under Miami-Dade sun.
Seam and Fastener Failures
The most common metal roof problem in Kendall isn’t rust. It’s failed fasteners. Neoprene washers dry out and crack after a decade of UV exposure, letting water track down the screw threads. We replace the fasteners, reseat the panels, and check the seams for any separation before resealing everything.
Metal-to-Tile Transitions
Where a metal patio roof ties into the main house, the flashing usually fails first. We’ve rebuilt dozens of these transitions in Kendall, and the fix always includes stripping the old sealant, installing new flashing, and tying the underlayment together so water can’t run behind either system.
Commercial Roof Repair in Kendall
Commercial Roof Repair in Kendall covers low-slope and flat systems on retail centers, offices, and mixed-use buildings along Kendall Drive, SW 117th Avenue, and the commercial corridors near Dadeland. Most commercial flat roofs here run $1,200 – $4,800 per repair depending on the membrane type, the size of the affected area, and whether the decking underneath has started to rot.
Modified Bitumen and Single-Ply Patches
Kendall’s commercial buildings cycle through brutal UV exposure and summer ponding. That combination oxidizes modified bitumen until it looks like cracked leather. We cut out the damaged section, inspect the decking, install a new membrane patch with the right NOA-documented materials, and seal the seams before we leave.
Drainage and Ponding Corrections
When water ponds over a low-slope commercial roof for more than 48 hours after a storm, the membrane ages twice as fast. We’ll identify the low spots, repair the membrane, and often add tapered insulation or a small scupper adjustment so the water actually leaves the roof.
Trusted Brands We Service in Kendall
We repair and install shingle brands that Kendall homeowners and their insurers know: GAF, CertainTeed, Owens Corning, and more. Because we’re in Kendall multiple days a week, we stock common flashing profiles, underlayment, and fasteners locally, which means shorter turnaround when your roof needs a repair before a re-inspection or a storm. We also work with the tile and flat-roof systems that dominate Kendall’s housing stock, and we document every product’s Miami-Dade NOA approval in writing so there’s no friction if your insurer or a county inspector asks for proof.
Common Roof Repair Problems We See in Kendall Homes
- Cracked and lifting tile on 25-to-30-year-old roofs. The post-Andrew re-roofing wave covered Kendall in barrel tile between 1993 and 1997. That tile is aging out now, and cracked mortar plus lifted tiles expose underlayment that was installed before the secondary water barrier requirement existed.
- Oxidized flat-roof membranes over rear additions. Kendall’s CBS homes were commonly built with flat or low-slope sections over patios, screened enclosures, and later additions. Summer surface temperatures over 160°F bake modified bitumen and single-ply membranes until they crack and leak.
- Failed flashing at tile-to-flat transitions. Where a barrel tile main roof meets a flat rear addition, the flashing detail is the weak link. In the post-Andrew wave, many of those transitions were tied into the underlayment incorrectly, and they leak years before the tile itself fails.
- Insurer flags on underlayment, not visible damage. Kendall homeowners are now getting non-renewal notices for roofs that look fine from the ground. The issue is the missing secondary water barrier, and we can identify that gap during a repair inspection before the homeowner even calls their carrier.
Pricing for Roof Repair in Kendall, FL
Here’s what Kendall homeowners can expect: shingle replacement over a small section, $350 – $700. Leak repair on a tiled main roof, $500 – $1,200.

What moves the number is whether we can repair cleanly or need to expose and replace decking or underlayment, which triggers Miami-Dade HVHZ inspection requirements.

FAQs About Roof Repair in Kendall
Insurers are non-renewing or surcharging policies on Kendall roofs built during the 1993 – 1997 post-Andrew re-roofing wave because those roofs lack the secondary water barrier now required under Miami-Dade code. The tile looks fine from the ground, but the underlayment underneath doesn’t meet the current standard, and insurers flag it. We can identify that missing-barrier gap during a repair inspection. Call (743) 200-8347 and we’ll tell you exactly what your roof has before you call your carrier.
Yes, most roof repairs in Kendall require a permit, and Miami-Dade County’s High Velocity Hurricane Zone rules require that all roofing products carry a Miami-Dade Notice of Acceptance. We pull the permit, use NOA-documented materials, and document everything in writing. If the repair exposes decking or underlayment, the inspector verifies nail patterns and underlayment specs, and we scope for that before work starts so the repair doesn’t stall at inspection.
Most barrel tile roofs installed in Kendall between 1993 and 1997 are reaching functional end-of-life at 25 to 30 years, even when the tile itself still looks decent. The bigger issue is the underlayment underneath, which was installed under first-generation post-Andrew code and lacks the secondary water barrier that current Miami-Dade rules require. We inspect the whole system, not just the visible tile. Estimates are free, and we’ll show you what we find.
Yes, in most cases we can repair or replace just the flat section over your rear addition, screened enclosure, or covered patio without touching the main tile roof. The work usually involves removing the oxidized membrane, repairing the decking if needed, replacing the membrane with an NOA-compliant product, and rebuilding the tile-to-flat transition flashing. A typical flat-roof repair over a Kendall rear addition runs $500 – $950. Call (743) 200-8347 for a written quote.
Before you sign, confirm three things: that the roofer is using NOA-documented products, that the written quote includes any Miami-Dade inspection requirements triggered by the repair, and that the guarantee is in writing with a specific duration. Mercer’s guarantee is 365 days, in writing, on every repair, and if a repair fails within that year we come back and make it right at no charge. Every price is written before work starts, never conditional. Call (743) 200-8347 for a quote that answers all three questions up front.
