Roof Installation in Orlando - Free Roof Inspection, Written Price

Trusted Roof Installation for Orlando Homeowners

A new roof over your head is one of the largest investments you will make in your Orlando home, and it only works if the company behind it treats your house like a home rather than a job site. Mercer Roofing Co Orlando has handled roof installation across Orange and Seminole counties since our founding in 2000, and we built our reputation on something most roofers never mention: you will know exactly who is walking up your driveway before the truck parks. Every technician’s name and photo is sent to you ahead of the visit, and when the doorbell rings, that same person presents a photo ID badge in a clean, marked uniform. No mystery contractors, no “guy with a truck” surprises. Grant Whitlock set the standard here, and every roof we install comes with a written price before work begins and the 365-Day Done Right Promise behind it.

Shingle Roof

A Shingle Roof is what you see on the vast majority of Orlando homes in neighborhoods like Hunters Creek, Ocoee, and Lake Mary, and for good reason: architectural asphalt shingles hold up to Florida sun, wind-driven rain, and the occasional tropical storm better than most people expect. We install shingle roofs using manufacturer-recognized brands including GAF, CertainTeed, and Owens Corning, with a full tear-off, new underlayment, new flashing, and dimensional shingles that carry 25-year to lifetime material warranties depending on the line. A typical Roof Installation in Orlando runs $8,500 to $16,500 for an average 2,000 to 2,600 square foot home, with steeper pitches, multiple stories, and decking replacement pushing that number higher.

Before you sign anything, we put every line item in writing, including the cost to replace rotted decking if we find it after tear-off. That written price is not an estimate that drifts; it is the price, and if the final invoice does not match, you already have our promise in writing.

Asphalt shingle materials and wind ratings

In Orlando, we regularly see shingle failures tied to two things: improper fastening during installation and underlayment that gets brittle in attic heat. That is why we use high-temp synthetic underlayment on most re-roofs and nail shingles to manufacturer spec, not to a roofer’s preference. We also check the attic before nail one goes down, because ventilation issues can shorten a shingle roof’s life by years.

When to choose shingles over other systems

Shingles make sense for homeowners who want solid protection without the price tag of metal or tile, and for most Orlando subdivisions, shingle is also the HOA-approved choice. If your roof pitch is lower than 2:12, shingles are not an option and we will steer you toward a membrane system like TPO instead. We would rather explain that upfront than sell you a roof that fails in three years.

Standing Seam Metal Roof

A Standing Seam Metal Roof is the premium choice for Orlando homeowners who want a roof that can outlive two shingle replacements and shrug off hurricane season without losing granules to the gutter. The system uses interlocking vertical panels with concealed fasteners, so there are no exposed screws to back out, no nail heads to rust, and no seams for wind to pry open. In Orlando, a standing seam metal roof typically runs $22,000 to $42,000 for an average home, depending on panel gauge, roof complexity, and whether we are tearing off the old roof or installing over an existing deck.

Mercer Roofing Co Orlando crews have installed standing seam on houses from Conway to Clermont, and we handle the details most crews skip: proper clip spacing for thermal movement, high-heat underlayment, and custom trim at hips, valleys, and eaves. Every metal roof we install gets the same 365-Day Done Right Promise and written price before the first panel is cut.

Energy and longevity differences

Metal reflects solar heat instead of absorbing it, which is a real number on your cooling bill between June and September. You can expect 40 to 60 years from a properly installed standing seam roof, and the only maintenance is an occasional rinse and checking that tree debris is not sitting against the panels. For Florida homeowners planning to stay put, that math is hard to argue with.

Coastal and storm considerations

Even inland Orlando gets wind-driven rain from bands that spin off Gulf and Atlantic storms, and standing seam has the highest wind ratings of any residential roof system. The concealed fastener design removes the weak point that causes panel loss on exposed-fastener metal roofs. If you are in a neighborhood with strict HOA rules, we can provide sample panels and wind-load documentation before you commit.

Tile Roof

A Tile Roof is the look that defines Florida luxury homes across neighborhoods like Bay Hill, Windermere, and parts of Oviedo, but it is also a real engineering system that demands an installer who understands underlayment, battens, and point loads. Concrete and clay tile in Orlando typically run $18,000 to $38,000 installed, with clay on the higher end and concrete more accessible, and both require a structure that can handle the extra weight before we proceed. Tile lasts 50 years or more when installed correctly, but the underlayment underneath usually needs replacement at the 20 to 30 year mark, which is the part many homeowners never see coming.

Mercer Roofing Co Orlando inspects the deck, the rafters, and the existing underlayment before we quote a tile roof, because tile failures are usually underlayment failures. We use a double-layer high-temp underlayment system, nail every tile to spec, and flash every penetration with materials that match the lifespan of the tile itself.

Weight and structural evaluation

Tile is heavy: concrete runs 600 to 1,000 pounds per square, and if your home was built for shingles, the trusses may not be rated for it. We will tell you that before you spend a dollar on tile. When the structure does allow tile, the payoff is a roof that looks better at year 30 than most shingle roofs look at year 10.

Underlayment and leak prevention

The tile itself sheds water, but the underlayment is what keeps water out, and Orlando humidity accelerates underlayment aging even when the tiles look pristine. We install high-heat synthetic or modified bitumen underlayment depending on the tile system, sealed at every penetration and valley. A leaking tile roof is almost never the tile; it is what is underneath, and we design that layer to fail after the tile does, not before.

Roof Ventilation

Roof Ventilation is the difference between an attic that stays under 130°F in August and one that bakes your shingles from underneath, raises your cooling bill, and feeds mold growth in the humid Orlando air. A proper ventilation system balances intake at the soffits with exhaust at the ridge or gable, moving air continuously without mechanical power. On a new Orlando roof installation, adding or correcting ventilation typically costs $900 to $2,800 depending on the home’s size and what is already in place, and it is one of the least expensive ways to extend the life of the roof you are paying for.

Mercer Roofing Co Orlando calculates ventilation requirements using the 1:300 rule from building code: one square foot of net free vent area for every 300 square feet of attic floor, split between intake and exhaust. We measure your existing soffit vents, check for blockages from old insulation, and add ridge vent or box vents where the math says they belong.

Attic heat and shingle life

An overheated attic can push shingle temperatures past 180°F, and that heat accelerates granule loss and premature cracking. We see it in Orlando all the time: a 12-year-old shingle roof that looks 20 years old because the attic never breathed. Ventilation is not an upsell; it is the part of the installation that protects the other parts.

Exhaust and intake balance

Exhaust without intake does not work, and intake without exhaust is just a hole. The system has to be balanced, and on a re-roof, the tear-off is the cheapest time to add ventilation because the deck is exposed and the labor is already on site. We include a ventilation assessment in every roof installation quote, and we write down what we find, right there in the estimate.

Roof Flashing Installation

Roof Flashing Installation is the metal work at every joint, corner, and penetration that keeps water from finding its way into your Orlando home, and it is the part of a roof installation that separates a 30-year roof from a 5-year leak. Flashing goes at chimneys, skylights, vent pipes, valleys, sidewalls, and anywhere the roof meets a vertical surface, and if it is done wrong, the shingles above it do not matter. Flashing installation on a new Orlando roof typically adds $1,200 to $3,800 depending on how many penetrations and dormers the home has, and we use galvanized steel, aluminum, or copper depending on the application.

Mercer Roofing Co Orlando replaces every piece of flashing on a full roof installation. We do not reuse old step flashing, we do not caulk over rotted base flashing, and we do not rely on roof cement where metal should be doing the job. Every flashing detail gets written into the estimate so you can see exactly what you are paying for.

Valley and sidewall flashing details

Valleys carry more water than any other part of the roof during an Orlando afternoon thunderstorm, and open metal valleys with proper underlayment outperform shingled-over valleys in heavy flow. At sidewalls, step flashing is the standard: each shingle course gets its own flashing piece, counter-flashed and sealed. We cut open old valleys and sidewalls to see what is underneath before we quote, because hidden rot changes the scope.

Pipe boots and penetration failures

That little rubber boot around your vent pipe is flashing, and in Florida sun it dries out, cracks, and leaks long before the shingles around it fail. We install all-metal or high-heat silicone pipe boots on every new roof, not the plastic-and-rubber version that comes with the cheapest bid. It costs a few dollars more and saves you a ceiling repair in year six.

TPO Roofing Installation

TPO Roofing Installation is the membrane roof system we install on flat and low-slope portions of homes, additions, carports, and porches across Orlando, where water wants to pool instead of run. TPO is a white, heat-welded single-ply membrane that reflects UV, resists standing water, and handles the thermal expansion that comes with Florida’s temperature swings. On an Orlando home, a TPO roof typically runs $7,000 to $15,000 depending on square footage, insulation needs, and whether the existing roof is being torn off or recovered, and the seams are hot-air welded, not glued.

Mercer Roofing Co Orlando installs TPO on flat decks, sunrooms, and low-slope sections where shingles are not rated to work, using mechanically attached or fully adhered systems based on the deck structure. We inspect the drainage first, because a flat roof that does not drain is a problem no membrane can solve, and we write the insulation and membrane details into the written price before work starts.

Flat and low-slope applications

Shingles need pitch to shed water, and anything under 2:12 is a candidate for TPO. Orlando homes with flat-roof additions or mid-century designs frequently have TPO as the only correct answer, and the white surface drops surface temperatures enough to make a difference in the rooms below. We also install TPO on porch covers and carports where the slope is nearly zero.

Seam welding and leak resistance

The reason TPO outperforms older rolled roofing is the heat-welded seam: the membrane pieces are melted together at the molecular level, not overlapped and glued. We test every seam with a probe after welding, and every penetration gets a TPO boot and cover strip. When a TPO roof leaks, it is almost always at a seam or a penetration, which is exactly where we focus the inspection before we quote.

Brands We Service

We install and service roofs from the manufacturers homeowners actually ask for: GAF, CertainTeed, and Owens Corning are the shingle lines we most often put on Orlando homes, and we know their installation specs without opening the wrapper. GAF’s Timberline HDZ and UHDZ lines are the most popular choices in the Orlando market, and we install them to GAF’s published specifications so the manufacturer warranty is valid, not just attached to the box. CertainTeed’s Landmark series offers some of the best granule retention and color consistency we see in Florida sun, and Owens Corning’s TruDefinition Duration shingles handle wind and impact better than most in their class.

We also work with Boral concrete and clay tile systems for homeowners who want a tile roof that meets Miami-Dade wind standards, and Atlas, IKO, and Tamko when a homeowner has a specific line they prefer or an existing roof we are matching. Whether you have a brand picked out or you want us to recommend the right system for your Orlando home, we will put the options, the specs, and the prices in writing so you can compare them side by side. Call (850) 757-3564 and we will walk you through what each brand actually costs installed, not just per square.

Signs You Need a Pro Right Now

• Granules collecting in your gutters or at the downspout exits. Losing granules means the shingle’s protective top layer is wearing away, and once the asphalt underneath is exposed to Orlando UV, the shingle deteriorates quickly. If you see a spoonful of granules every time you clean the gutters, the roof is telling you something.
• Water stains on the ceiling or upper wall after a heavy rain. By the time water shows up inside, it has already passed through the roof deck, and what you see is only the last stop on a longer path. The actual entry point may be several feet away, which is why we trace the stain back, not just seal the spot where it drips.
• Shingles that are curling, cupping, or lifting at the edges. Curled shingles are not just cosmetic: they create wind lips that catch gusts during summer storms and pull up entire sections. An afternoon thunderstorm rolling through Ocoee or Oviedo with 50-mile-per-hour gusts can peel a weakened roof open before the rain even starts.
• Light visible through the roof deck from inside the attic. If you can see daylight at the ridge or around vent pipes, water has a path in too. This is one of the easiest checks a homeowner can do, and it is one of the first things we check when we inspect an Orlando roof, because you are literally looking at the hole in your roof.
• Your energy bill climbs in summer without an obvious reason. A roof that has lost its reflectivity or a ventilation system that stopped working forces your AC to fight a hotter attic, and the bill is where that fight shows up. In Orlando’s eight-month cooling season, the difference between a ventilated roof and a stifled one can be meaningful money every single month.

Our Process, Step by Step

1. 1
   Written estimate with line-item pricing. We inspect the roof from the deck up, take measurements, check the attic ventilation, and then hand you a written price that lists every material, every labor item, and every allowance for decking replacement before you sign anything. That price is the price, and if the scope changes, you see the change order in writing first.
2. 2
   Material and permit coordination. Once you approve the written estimate, we order the shingles, underlayment, flashing, and ventilation components from the manufacturer, and we pull the Orlando or Orange County permit for the project. Permits mean the roof gets inspected by the local building official, which is protection for you, not paperwork for us.
3. 3
   Tear-off and deck inspection. The old roof comes off down to the deck, and this is where hidden problems surface: rotted decking from an old leak, loose rafters, or nails that never bit into anything. Every piece of damaged decking is pointed out to you before it is replaced, and the cost for that replacement is already in your written estimate as a stated allowance.
4. 4
   Installation to manufacturer spec. Underlayment goes down first, then ice and water shield in valleys and around penetrations, then flashing, then the roof system itself, nailed to the manufacturer’s published pattern. We install ventilation at this stage too, while the deck is open and the soffit-to-ridge air path can be verified.
5. 5
   Cleanup, inspection, and the Done Right Promise. We magnet-sweep for nails, haul every piece of debris, and walk the finished roof with you so you can see the flashing, the valleys, and the ventilation before we leave. Then the Mercer Roofing 365-Day Done Right Promise kicks in: if anything is not right within a year, we make it right, and you have that in writing on every job.
