We’re Winslow Windows & Doors, and we’ve worked on hundreds of Largo homes since 2011. Ed Winslow’s name is on the door and on every job we do. Dispatch and scheduling for our Largo crews run through our South Florida office, but the technicians who show up at your door know this city. They know Pinebrook Estates, Harbor Hills, and the streets off East Bay Drive. They know what salt air does to aluminum flashing after ten years. And they know how a failed 4-point inspection can put a whole insurance renewal at risk.
Why Winslow Windows & Doors Is Largo’s Preferred Roof Repair Company
Largo homeowners call us because we answer the phone, show up when we say we will, and write quotes that match the final invoice. Ed Winslow founded this company in 2011, and he still personally reviews every job that touches a roof-to-window transition or a rated opening. That ownership matters in Largo, where the Roof Repair in Largo market is driven less by curb appeal and more by insurance survival.
Our Largo customers consistently tell us the same thing: other contractors looked at the roof and missed the window flashing, the corroded sill track, or the wind-mitigation seal that was about to fail. We don’t miss those details, because we repair roofs and install impact-rated windows and doors. That gives us a diagnostic edge no shingle-only roofer can match. Every technician who arrives at a Largo home is background-checked and in uniform. A live person answers our phone 24 hours a day, seven days a week, not a voicemail loop or a call center.
Every job carries the 36500-Day Done Right Promise: if it’s not done right, we make it right. That promise has no fine print and no expiration date. We also hold a published license number and a physical address, so you know exactly who you’re dealing with before the truck pulls up.
Our Roof Repair Services in Largo
Our Roof Repair team handles the full range of exterior water-intrusion work on Largo homes, from emergency leak mitigation to complete roof-to-wall re-flashing. Here’s what we do most often in this city.
Roof-to-Window Flashing and Sealant Restoration
Largo’s salt-laden Gulf air corrodes aluminum flashing around jalousie and single-pane aluminum windows faster than almost anywhere else in Florida. We replace failed flashing with marine-grade metal, re-bed sealant, and document the repair so your wind-mitigation credit stays intact. If the roof is leaking at the window corner, the problem is almost never the shingle itself. It’s the transition.

Low-Pitch Hip Roof Leak Repair
Most Largo homes built between the late 1940s and early 1980s are single-story concrete block with low-pitched hip roofs. Those roofs shed water slowly, and any breach at a flashing point lets wind-driven rain pool into the deck. We repair the deck, replace the underlayment, and seal every transition point to current Florida Building Code standard.

Wind-Mitigation Documentation Support
When roof repair touches a rated opening, we document it on your OIR wind-mitigation form. That paperwork can mean the difference between keeping an $800-$2,000 annual insurance credit and losing it entirely. Many Largo homeowners don’t realize that a careless DIY repair around a single-pane sliding door can void their credit and trigger a failed inspection. We make sure the work is done right and the record reflects it.

Emergency Roof Repair in Largo
Storm season brings sudden leaks, lifted flashing, and water coming through the ceiling at 2 a.m. When that happens in Largo, call us. Someone answers. We assess the damage, stop the active leak, and schedule the permanent repair. You won’t talk to a ticket number or an answering service.

Trusted Brands We Service in Largo
Our roof repair work frequently involves openings built by PGT, Mr-Glass, and Therma-Tru, and our technicians are factory-trained on those product lines. When a roof leak around a PGT impact window needs a new gasket or seal, we know which replacement part the opening needs, and we stock the common ones locally so Largo customers aren’t waiting on a two-week backorder. Same story with ViewLux and CGI units we encounter during storm restoration. You don’t have to chase down the original installer or a national brand’s support line. We handle it.
Common Roof Repair Problems We See in Largo Homes
- Corroded flashing at jalousie windows: Original jalousie windows under a leaking eave let wind-driven rain saturate the roof deck. A roofer who doesn’t understand window frames will patch the shingle and miss the rot underneath.
- Salt-air corrosion on aluminum transitions: In Largo, aluminum roof flashing at the sill track corrodes within 10 to 15 years. The result is a persistent roof leak that no amount of shingle replacement will stop, because the problem is at the wall intersection, not the field.
- DIY repairs breaking the wind-mitigation seal: We regularly see roof patches around single-pane aluminum sliding doors that voided the homeowner’s wind-mitigation inspection. The homeowner saved $200 on the repair and lost $1,400 a year on the premium.
- Lifting drip edge on low-pitch roofs: Salt air and high-wind cycling work the drip edge loose over time, especially on the east-facing roof planes that catch the bay weather. Once it lifts, water gets under the underlayment and the deck starts to rot from the underside.
Pricing for Roof Repair in Largo, FL
Here are the numbers, honest and upfront. Flashing repair around a single window or door in Largo runs $350-$700. Replacing a corroded drip edge along one roof plane runs $500-$900. Roof deck repair below a leaking jalousie window runs $600-$1,800 depending on how much decking we have to cut out and replace. Full roof-to-wall re-flashing on a typical low-pitch Largo hip roof runs $1,200-$3,500, depending on the number of openings and the condition of the existing transitions.
What moves the price in Largo: the number of window and door openings that meet the roof, whether the deck has hidden rot, and whether the existing flashing is original 1960s aluminum or a newer marine-grade product. We give free in-home estimates, written line-item quotes, and fixed pricing with no change orders. Call (386) 559-6999 to schedule yours.
What Roof Repair Costs in Largo
For context beyond the repair itself, many Largo homeowners use a roof repair project as the moment to address the openings that are causing the problem. Impact windows in Largo generally run $800-$1,500 per window installed. Impact single-hung units run $900-$1,800. Large custom openings like picture windows or sliding glass doors run $2,500-$5,000. Whole-home packages, where we replace every jalousie and single-pane aluminum opening with Florida Product Approval-rated impact glazing, typically run $8,000-$25,000+ depending on opening count and wind-zone design pressure requirements.
In Largo, the wind-zone design pressures are real, particularly for homes closer to the bay or on elevated pads. The number of openings, the frame material, and the floor height all move the price. What doesn’t move: our commitment to written quotes that match the final invoice. We offer a free in-home measure and written quote with every estimate. Call (386) 559-6999 and we’ll come out.
Florida Pays You Back
Largo homeowners have more incentive help available than almost any other market in the country. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades on your primary residence. The state of Florida exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit can return 30% of product cost, up to $600 per year, on qualifying energy-efficient units. And after a wind-mitigation inspection, which typically costs $75-$150, most Largo homeowners see their windstorm premium drop by roughly 25% on the wind component.
We don’t set those numbers, and we don’t guarantee what your carrier or the state will do. The programs and the carriers make the final call. What we do is document every repair and installation to the standard the inspector expects. In Largo, a roof repair that touches a rated opening is either a wind-mitigation asset or a liability. We make sure it’s the former.
One more honest comparison worth knowing: impact windows versus hurricane shutters. Shutters protect the opening, but only when someone’s home to hang them, and they do nothing for energy efficiency or insurance credits between storms. Impact windows work permanently, with no panels to haul out of the garage in September. We don’t install shutters. We install permanent, code-rated impact protection that keeps working every day of the year.

FAQs - Roof Repair in Largo
Yes, it can, and that’s the whole point. A proper roof repair around original jalousie windows preserves or restores your OIR wind-mitigation credit, which typically saves Largo homeowners $800-$2,000 per year on insurance. A careless repair that breaks the seal around the opening can void that credit and trigger a failed 4-point inspection. We document every repair for the wind-mitigation form. Call (386) 559-6999 if you want the work done and the paperwork done right.
Largo sits at the geographic center of the Pinellas Peninsula, flanked by Tampa Bay on one side and the Gulf of Mexico on the other. That means every structure is in a high-wind design zone, and the constant salt-laden air off the Gulf accelerates corrosion of aluminum frames, sill tracks, and flashing. We routinely see seal failure and frame pitting on Largo homes that are only 10 to 15 years old. Inland homes don’t face that salt load, and their flashing lasts decades longer as a result.
You can absolutely repair just the roof section above the windows, and for many Largo homeowners that’s the right first step. We repair the roof deck, replace the flashing with marine-grade metal, and document the fix. We’ll also give you an honest read on whether the window itself is nearing the end of its life. If the frame is corroded to the point that it can’t hold a proper seal, we’ll tell you, and we’ll price a replacement with PGT, Mr-Glass, Therma-Tru, or ViewLux units. You decide. We don’t pressure you into replacement when a repair is sufficient.
The proper detail is a marine-grade metal flashing that extends up the wall past the door’s sill track, with a continuous sealant bead that bonds to the door frame without trapping water. The roof-side leg must lap under the underlayment, not over it, so wind-driven rain is directed down the flashing and off the roof. Most original Largo installations got this backward or used thin aluminum that corroded within a decade. We re-flash to current Florida Building Code standard and match the detail to the specific door’s design pressure rating. Call (386) 559-6999 for a free inspection of your existing transition.
For a straightforward flashing repair or sealant restoration, no permit is required in Largo. When we cut into the roof deck or replace underlayment, we pull the necessary permits and schedule inspections, and we’ll confirm the exact requirement for your specific job during the free estimate. If the repair touches a rated opening, we document it for your wind-mitigation form regardless of whether a permit was needed. We don’t cut corners on paperwork, because we know how closely Largo insurers and inspectors look at these jobs.
