Fast, Reliable Roof Installation Across Westwood Lakes
A full roof installation in Westwood Lakes typically costs between $12,000 and $28,000 for a single-family home, with concrete tile reset and reunderlayment work landing in the $8,000 to $15,000 range. Most projects take five to nine working days once permits clear Miami-Dade County. We work throughout Westwood Lakes, from the acreage lots off SW 162nd Ave down to the smaller residential streets near Kendall Drive, and we answer the phone at (850) 753-2996 whenever you call.
Westwood Lakes isn’t like the rest of Miami-Dade. You’re in unincorporated county territory, which means your permits, inspections, and code enforcement all flow through the county’s Building Official, not a municipal office. That changes how a roof installation gets scoped, priced, and inspected. We know the county’s High-Velocity Hurricane Zone requirements because we deal with them on nearly every Roof Installation we do here. Getting the underlayment rating, tile attachment, and uplift documentation right the first time is what keeps your job from stalling at inspection.
You’ll also notice that Westwood Lakes homes sit on bigger lots than you’d find in Miami or Miami Gardens. That’s good for privacy, but it changes how roofing materials move across your property, where the county will let us stage tile pallets, and how septic and well setbacks shape the work zone. We plan for all of it before we hand you a written price.
Why Mercer Roofing Co Miami Is Westwood Lakes’s Preferred Roof Installation Company
We’re part of the Threshold Group family, founded in 2000, and every Mercer location operates under the Threshold Verified standard. That standard is the reason we send you a photo and name of your technician before they arrive, and why they badge in at the door with a photo ID. If you’re home alone, have young kids, or just don’t like the idea of an unverified stranger on your roof, that’s a concrete difference you’ll notice the moment we show up.
Grant Whitlock runs our team with a straightforward rule: every price gets written down before any work starts, and every repair carries a written guarantee. If the work isn’t right within 365 days, we come back and make it right. No fine print, no phone tag. You call, a live person answers, and we schedule the fix.
In Westwood Lakes specifically, we’re the crew that recognizes the original 1990s S-tile concrete roofs by their faded terracotta color and the cracked hip-and-ridge pieces that start dislodging after decades of thermal cycling. That recognition isn’t trivia. It tells us whether your roof needs a full tear-off or a carefully scoped tile reset with new underlayment. And that decision is worth thousands of dollars either way.
Styles & brands we work with
Roof Flashing Installation in Westwood Lakes
Roof flashing installation in Westwood Lakes is the work of sealing every joint, valley, chimney, and pipe penetration where water would otherwise find a way in. On the Mediterranean-style homes common to this area, original copper or galvanized flashing from the 1980s and 1990s is often corroded through at the valleys and around skylights, even when the tile overhead still looks serviceable. When we install a new roof here, we replace that flashing as standard, not as an add-on.
A full flashing replacement during a Westwood Lakes roof installation adds roughly $1,500 to $3,500 depending on how many valleys, chimneys, and penetrations your home has. If you’re only replacing flashing without a full roof job, expect $750 to $2,200.
Valley and penetration flashing on tile roofs
Valleys on low-pitch hip roofs carry the heaviest water volume during a South Florida downpour. We cut and bend new copper or aluminum valley flashing on site, lap it under the tile, and secure it so it won’t lift in a storm. On tile roofs, we also install new pipe boots and painted metal flashing around stacks, vents, and curbs.
Flashing when resetting original tile
If your field tiles are fine but the flashing has failed, we don’t force a tear-off. We reset the surrounding tile, remove the old flashing, install new material, and re-bed the tile on fresh mortar or approved adhesive, matching the existing profile so it looks original, not patched.
TPO Roofing Installation in Westwood Lakes
TPO roofing installation in Westwood Lakes is what we recommend for flat or very low-slope roof sections: attached lanais, carports, patio covers, and the occasional flat-roofed addition. TPO is a white, heat-reflective single-ply membrane that handles Miami’s UV load better than older modified bitumen roofs and keeps the underside cooler. If you’ve got a flat section leaking over a porch or a shed, this is usually the answer.
A TPO roof on a typical Westwood Lakes lanai or flat section runs $6 to $9 per square foot installed, which puts most jobs between $3,500 and $7,500. Full tear-off of the old flat roof material adds $1 to $1.50 per square foot when the existing decking is sound.
TPO for lanais and flat additions
We mechanically fasten or fully adhere the membrane depending on the deck condition, then heat-weld the seams so they can’t open up like older taped systems. Around edges and penetrations, we install new TPO flashing and termination bar, which is where most flat roof leaks actually start.
TPO over existing roof decks
When the existing decking is solid and dry, we can often go directly over the old roof with a cover board and new TPO, which saves the cost of a full tear-off. We’ll confirm the deck condition during the estimate, not mid-job, so the price we quote is the price you pay.
Trusted Brands We Service in Westwood Lakes
We install and service shingle and tile systems from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Westwood Lakes homes with original concrete tile, we typically work with replacement tile from Boral and Eagle, matched to the original profile and color as closely as the manufacturer allows. For the rare shingle roof in this area, Atlas and IKO offer high-wind-rated lines that meet Miami-Dade product approval requirements. Because we’re in Westwood Lakes regularly, we can often source matching tile and accessories from local supply houses in days, not weeks, which keeps your project moving once the county approves the permit.

AfterCommon Roof Installation Problems We See in Westwood Lakes Homes
- Original underlayment failing under 30-year-old tile. The concrete tile on 1980s and 1990s homes often still looks good from the street, but the asphalt-saturated felt beneath it has dried out, cracked, and stopped shedding water. We see this in the stained ceilings under otherwise intact roofs. The fix is a tile reset with new underlayment, not a full tear-off.
- Cracked and dislodged hip-and-ridge pieces. The S-tile profile common in Westwood Lakes puts a lot of stress on hip and ridge caps. After 25 to 35 years of thermal cycling, those caps crack, loosen, and start sliding. A dislodged ridge piece is an open invitation for water and wind-driven rain.
- Ponding water on flat lanai roofs. Flat TPO and modified bitumen roofs over lanais and carports often show ponding near the house wall. That standing water accelerates flashing corrosion and pushes water under the membrane at the intersection. Proper slope correction and new flashing are part of any flat roof job we do here.
- County inspection failures on previous DIY or cut-rate jobs. Unincorporated Miami-Dade enforces HVHZ rules that city permit offices sometimes gloss over. We’ve been called in after a homeowner failed inspection because the previous installer reused tile without documenting uplift resistance or couldn’t produce the underlayment’s Miami-Dade Notice of Acceptance. We pull the right paperwork before we start, not after the inspector leaves.
Pricing for Roof Installation in Westwood Lakes, FL
A full concrete tile roof installation on a typical Westwood Lakes single-family home runs $18,000 to $28,000. A tile reset with new underlayment and flashing, where the field tile is sound, runs $8,000 to $15,000. TPO flat roof work runs $6 to $9 per square foot. Flashing-only work on an existing roof runs $750 to $2,200. The biggest price drivers are roof size, whether you need a tear-off or a reset, the number of valleys and penetrations, and how far materials have to be hauled across your lot from the street. We put every number in writing before any work starts, and the price doesn’t change unless you change the scope. Call (850) 753-2996 for a free, written estimate.

FAQs About Roof Installation in Westwood Lakes
Yes. Westwood Lakes is unincorporated Miami-Dade County, so roof installation permits come from the county’s Building Official, and county inspectors perform the underlayment, in-progress, and final inspections. The county enforces High-Velocity Hurricane Zone codes, which require specific underlayment ratings, tile attachment methods, and uplift documentation. We handle the permit package and the inspections as part of the job. Call (850) 753-2996 and we’ll walk you through the process.
In most Westwood Lakes homes, cracked hip-and-ridge pieces with sound field tile means a reset is the right call, not a full tear-off. We remove the damaged caps, inspect the underlayment beneath them, replace the failed sections, and install new matching hip-and-ridge pieces. If the field underlayment is also failing, we’ll see that during the estimate and scope it accordingly. Call (850) 753-2996 for a written quote on either approach.
Yes. Detached structures add a second or third roof plane to the job, and the material haul distance from the street to the outbuilding drives labor and equipment costs up. We scope every structure on your lot during the estimate, including lanais, carports, and ADUs, so the quote you get is the quote you pay.
Septic drain fields and well heads have required setbacks that limit where we can stage tile pallets, place dumpsters, and run equipment. On larger Westwood Lakes lots, that often means staging materials near the street and using a telehandler or longer carry distances. We map those setbacks before quoting so access costs are included up front. Call (850) 753-2996 and we’ll come look at your lot.
In South Florida, ice and water shield isn’t for ice. It’s a self-adhered, high-temp peel-and-stick membrane that seals around nails and protects against wind-driven rain, which is the real threat during hurricane season. Miami-Dade HVHZ codes require specific underlayment performance at eaves, valleys, and penetrations. We use it on every Westwood Lakes roof installation, regardless of the tile or shingle system going on top. Call (850) 753-2996 for a free estimate and we’ll show you exactly where it goes.
