What Happens During Your Jacksonville Reroof

Booking the Date and Protecting the Yard

A signed contract in Jacksonville locks in a crew, not a calendar date, since June through September brings afternoon thunderstorms that can push a start by a day or two. Homeowners in Mandarin, Arlington, and the Westside all work around the same forecast window. Material delivery gets timed close to the start so shingle bundles aren't sitting exposed on a driveway through a week of humidity and rain before work begins.

Before anyone touches the roof, the ground gets covered. Tarps go over shrubs and flower beds, especially in older Riverside and Avondale yards with mature landscaping close to the house. Pool cages and patio furniture get shielded or moved. Plywood leans against siding near ladders so nothing gets scuffed. Downspout openings sometimes get covered too, keeping shingle grit and nails out of the drainage line running toward the yard.

Deck inspection follows the tear-off, section by section, before any Jacksonville roof gets new material. The licensed pros we connect you with press on the exposed sheathing, looking for delamination, rot, or nail heads that spin instead of bite. Weak spots get cut out and replaced rather than covered over. Anything questionable becomes a change order, priced and approved before work continues, so there's no guessing about condition once the new underlayment goes down.

Stripping the Old Roof and Checking the Deck

The old roof comes off one section at a time so a wide-open deck never sits exposed through a Duval County afternoon storm cell that builds fast and drops heavy rain with little warning. Crews watch the radar and size each section to what can be dried in and covered before the sky turns. On a home near Pottsburg Creek or the Ortega River, that timing matters even more given how quickly low-lying yards can hold standing water.

Deck re-nailing happens once the old fasteners are visible, since decades of Jacksonville heat can loosen sheathing nails without any obvious sign from below. The crew adds fasteners along a pattern matched to current wind requirements rather than just the spacing the original builder used. Any deck panel that's split, spongy, or delaminated gets pulled and replaced with new sheathing cut to fit before anything goes back over it.

• Scheduling is set after the contract is signed, timed around Jacksonville's afternoon thunderstorm pattern so the deck is not left bare overnight.
• Property protection covers gutters, AC units, and flower beds before tear-off, since falling shingles and old nails damage anything left exposed below.
• Dumpster placement follows the driveway layout; a St. Nicholas or San Marco lot with limited street parking may call for a change order to reposition it.
• Tear-off comes off one roof plane at a time down to bare wood, so no more of the house sits open than the day's work allows.
• Deck inspection follows tear-off, checking every sheet of plywood for soft spots, since Jacksonville's rain load finds any gap in the decking fast.
• Re-nailing tightens fasteners that worked loose over the years and swaps any panel gone soft, giving the new underlayment a solid base to grip.

Underlayment, Flashing, and Every Penetration

Once the deck is sound, a synthetic underlayment sheet gets rolled across it in overlapping rows, sealing the plywood before a single shingle goes down. This sheet is what actually keeps water out during a driving summer rain; the shingles above it mostly take the sun and wind. Drip edge gets set along the eaves and rakes underneath or over the underlayment depending on the edge, giving runoff a clean line off the roof instead of behind the gutter.

A starter course of shingles runs along the eave before the field begins, sealing the first row's gaps so wind can't get under the leading edge. Valley metal goes down wherever two roof slopes meet, since that's where water from both sides funnels together and moves fastest. On a hip roof common in Mandarin and San Jose, those valleys and hip lines carry more runoff than any single flat plane, so the metal there has to lap correctly from the start.

• Underlayment covers every inch of exposed deck before lunch, so a sudden Jacksonville squall off the St. Johns River can't reach the plywood.
• Metal edging wraps the perimeter first, then the starter strip locks over it, aiming runoff away from fascia toward the gutters below.
• Valley metal goes in wherever two roof slopes meet, carrying the heavy runoff from Jacksonville's summer rain down and off without backing up underneath.
• Pipe boots seal around every vent stack, closing off the small gaps that turn into a stained ceiling a season or two after move-in.

Layer by Layer: Deck to Drip Edge

Chimneys, dormers, and any wall where an addition ties into the original house get new flashing, since old flashing is a common source of a leak that shows up weeks later as a stain on a ceiling. Step flashing gets layered piece by piece up a sidewall, each piece tucked behind the one above it and under the shingle course beside it, so water sheds down and away rather than working sideways into the wall.

Every plumbing vent and exhaust stack coming through the roof gets a fresh pipe boot, since the rubber collar on an old one cracks from sun exposure long before the surrounding shingles look worn. A dried-out boot is one of the quieter ways rain gets into an attic in Baymeadows or Southside homes, showing up as a damp spot near an interior wall months after the actual failure happened at the roofline.

From Starter Course to Ridge Cap

Field shingles go up row by row once the underlayment, drip edge, and flashing are set, with each course shifted over from the one below so the cut lines don't stack into a visible seam. The nailing pattern follows the shingle manufacturer's spec for Jacksonville's wind exposure, with fastener count and placement checked as the crew works up the slope rather than left to a single pass at the end.

Hip and ridge cap pieces close out the top of the roof, folding over the peak and any hip lines running down from it on homes throughout Arlington and Ortega. A ridge vent often runs underneath that cap on newer installs, letting attic heat escape along the roofline instead of building up under the deck through a Jacksonville summer, which is part of what keeps shingles from aging faster from the underside.

Final Sweep and the Walkthrough

Cleanup happens continuously, with old shingles and nails going into the dumpster as tear-off progresses rather than piling up in the yard until the end. Dumpster placement in Jacksonville usually lands in the driveway, close enough to the roofline that debris isn't crossing a lawn or a neighbor's property line to get hauled away. A magnetic sweep of the yard, driveway, and any flower beds nearby picks up stray nails before anyone walks the property barefoot.

A punch list gets written up for anything still open once the roof itself is done: a flashing edge that deserves a second pass, a gutter section knocked loose during tear-off, or a change order item like extra decking that got swapped in partway through. Each item gets checked off before the job is called finished, so nothing small gets left for the homeowner to notice on their own weeks later.
