Why Mercer Roofing Co Orlando Is Belle Isle’s Preferred Roof Installation Company
Belle Isle homeowners call us because we treat the front door the same way we treat the roofline. Every technician’s name and photo is sent to you before the visit, and they badge in with photo ID when they arrive. That matters to parents home with young kids, older homeowners, and anyone who simply doesn’t want a stranger on their property without proof of who they are.
We’re part of the Threshold Group family, founded in 2000, and every Mercer Roofing location is held to the Threshold Verified standard: background-checked, identity-verified, uniformed technicians on every job. On Belle Isle’s east side, where original 1950s ranches near Lake Conway carry decades of organic growth on their shingles, our crews have seen what humidity and oak canopy do to decking. That local knowledge means we don’t just replace what’s on top. We check what’s underneath before we quote.
Styles & brands we work with
Roof Ventilation in Belle Isle
Roof Ventilation in Belle Isle is not a luxury add-on. Our subtropical climate, with afternoon thunderstorms and humidity that rarely dips below 70 percent, turns a poorly ventilated attic into a moisture trap. On a mid-century ranch with a low-slope section, that trapped moisture shortens the life of your new shingles and can rot decking from the inside out. In Belle Isle, we recommend a balanced intake-and-exhaust system – typically ridge vent with soffit intake – sized to the attic’s square footage and the home’s specific roofline. Expect to pay $900 to $2,400 for a full ventilation upgrade on a typical Belle Isle home.
Attic Inspection and Airflow Correction
Before we sign off on any installation, our crew checks the attic for blocked soffit vents, bathroom fans venting into the attic, and signs of trapped moisture like rusted nail tips or damp insulation. Correcting airflow at the time of a new roof is far cheaper than replacing decking two years later.
Ridge Vent and Soffit Intake for Low-Slope Sections
Homes with flat or low-slope sections need more than a ridge vent, because air doesn’t move the same way across a nearly level plane. We install baffled soffit intakes paired with static or solar-powered vents sized for the square footage of the low section, which keeps the underside of the roof within a few degrees of the outside air.
Roof Flashing Installation in Belle Isle
Roof Flashing Installation in Belle Isle is where most summer storm leaks actually begin. Wind-driven rain during our afternoon thunderstorms finds its way through unsealed plumbing vents, chimney bases, and the juncture where a low-slope section meets a steeper pitch. The flashing is the metal that seals these penetrations, and on Belle Isle’s lakefront properties, we install it to hold up to 130 mph wind ratings and days of moisture. A complete flashing replacement as part of a new roof typically runs $1,200 to $3,800 depending on chimney count and penetration layout.
Chimney and Vent Pipe Repair
On the original 1950s ranches near Lake Conway, the chimney flashing is usually the first point of failure. Corrosion, separated counter-flashing, and old tar sealant let water ride the brick down into the attic. We replace the step flashing, counter-flashing, and vent boots with stainless or galvanized steel, then seal every seam with high-grade polyurethane.
Valley and Transition Flashing
Where two roof planes meet, or where a low-slope section transitions into a pitched section, the flashing has to move water quickly without letting it wick underneath. We use closed-cut or woven valleys on shingle roofs, with ice and water shield under the flashing layer as a second line of defense against wind-driven rain.
Trusted Brands We Service in Belle Isle
We install and warrant GAF, CertainTeed, and Tamko shingle systems, and we stock the common components those brands require so Belle Isle customers aren’t waiting on a truck from across the county. For high-end custom builds, we also work with Boral and Owens Corning lines. If your home has a low-slope or flat section, we’ll spec the brand’s modified bitumen or TPO system rather than forcing shingles onto a surface they were never designed for.

AfterCommon Roof Installation Problems We See in Belle Isle Homes
- Original decking rot from organic growth. On the east side near Lake Conway, decades of oak canopy shade and humidity have left widespread organic growth on decking and shingles. What looks like a simple reroof often becomes a decking replacement once we open it up.
- Shingles on low-slope sections that were never meant to have shingles. Mid-century ranches often have a low-slope carport or patio overhang that a previous contractor reroofed with standard shingles. Ponding water and leaks follow, and we correct it with a proper low-slope system.
- Wind-driven rain at unsealed penetrations. Summer thunderstorms push water sideways, and old plumbing boots and chimney flashing that held fine in a vertical rain start leaking. We seal every penetration as part of the install, not as an afterthought.
- Oak tree canopy shutting down ventilation. Homes with heavy oak coverage trap moisture in the attic and on the shingle surface, accelerating granule loss. We add mechanical ventilation and recommend tree canopy trimming where it’s blocking airflow, but we never require tree removal just to install a roof.

FAQs About Roof Installation in Belle Isle
Many original 1950s ranches near Lake Conway were built with quality decking and hand-nailed shingles, and their owners simply put off replacement until leaks forced the issue. That means we almost always find decking damage beneath the old roof, which changes the scope and price. Call (850) 757-3564 and we’ll inspect the decking before we quote so there are no surprises.
Wind-driven rain is the biggest threat, and we install every roof with ice and water shield at the valleys, penetrations, and low-slope transitions, along with 130 mph-rated shingles and sealed flashing. We also schedule our work around the summer storm pattern, removing only as much old roofing as we can recover before the next downpour. A written, fixed price covers the full scope before we start.
We recommend a proper low-slope system like modified bitumen or TPO, never standard shingles. Shingles on a near-flat surface hold water, which breaches the adhesive seal and rots everything beneath. For a specific recommendation and price, call (850) 757-3564.
We lock in the material price with a written contract before the long-lead items are ordered, so the cost doesn’t drift while you wait. Specialty underlayment, custom flashing, and designer shingle lines like CertainTeed Belmont can take 4 to 8 weeks, and we tell you the real timeline up front. The schedule is driven by delivery dates, not labor availability.
Yes, in nearly all cases. We install roofs around existing trees, add ventilation to offset the shading and moisture trapping, and may recommend selective canopy trimming for airflow, but removing a healthy oak is not required to install a proper roof. For a property-specific answer, call (850) 757-3564 and we’ll walk the site with you.
