Atlas Underlayment & Deck Repair: The Orlando Owner’s Guide
If your Atlas roofing system is leaking, lifting, or showing water stains on the ceiling, the underlayment or decking has likely reached the end of its service life. Tilehurst Roofing Orlando stocks Atlas-compatible underlayment and installs deck repair throughout the Orlando metro, with most underlayment replacements running $275 – $650 and deck repair typically landing between $450 – $1,200 depending on how many sheets need to come out. We’re usually out within a few days for non-emergency calls, and we’ll give you a written price before anything gets torn off.
Most Orlando homeowners discover the problem after a heavy afternoon thunderstorm. Water finds the weak spot, works through the underlayment, and darkens the decking underneath. By the time you see the stain on the ceiling, the plywood or OSB has often been wet for weeks.
How Much Does Atlas Underlayment & Deck Repair Cost in Orlando?
Underlayment replacement on an Atlas system in Orlando runs $275 – $650 for a typical repair area, while deck repair costs $450 – $1,200 depending on how many sheets of rotted or water-damaged decking need to be cut out and replaced. Full underlayment replacement on an entire roof (done during a re-roof) runs higher, but as a repair, those ranges reflect what we quote and honor across the Orlando area.
| Repair Type | Typical Orlando Price Range | What’s Included |
|---|---|---|
| Underlayment patch (small area, no deck damage) | $275 – $450 | Remove old felt/synthetic, inspect deck, install Atlas-compatible underlayment, seal edges |
| Underlayment replacement (medium area) | $450 – $650 | Larger section, re-nailing, ice & water shield in valleys if needed |
| Deck repair (1 – 3 sheets plywood/OSB) | $450 – $800 | Cut out rotted decking, replace with CDX plywood, re-secure to joists |
| Deck repair (4 – 6 sheets, structural work) | $800 – $1,200 | Larger repair, may include joist reinforcement, permit pulled if needed |
What drives the range? Deck thickness, whether we’re matching existing sheathing for a smooth surface, and how much of the old fastening system needs to be redone. We tell you the price before we touch the roof, and we mean it.

Which Atlas Models This Applies To
This covers the full Atlas residential line we work with across Orlando: Pinnacle Pristine, StormMaster Shake, GlassMaster, and the Architectural line, as well as older Atlas roofs still in service. If your roof was installed before Atlas moved to their HP42 and HP16 synthetic underlayment lines, you may be dealing with an older felt product that has reached the end of its life.
Here’s what matters for parts matching: decking is decking (3/8″ to 5/8″ CDX plywood or OSB, standard in Florida residential construction), but underlayment differs by material. Atlas’s newer synthetic underlayments (HP42, HP16) are rated for longer exposure than the older #15 and #30 felt. If your roof has original felt underlayment from 15+ years ago, we’ll upgrade to Atlas-compatible synthetic or an equivalent CertainTeed or GAF product, whichever matches your warranty and roof assembly best. The compatibility gotcha: some Atlas warranties require an Atlas-branded underlayment to maintain the system warranty. We’ll check your paperwork before we quote, because that requirement changes the material choice and the price.
Signs Your Atlas Underlayment & Deck Repair Is Failing
- Water stains on ceilings or walls – moisture has already penetrated the underlayment and soaked into the decking. The stain is the last symptom, not the first.
- Visible cracks in the decking from the attic side – wet-dry cycles in Orlando’s heat break down plywood and OSB. If you can see dark, cracked, or swollen sheathing from the attic, the deck is toast.
- Bubbled or wrinkled underlayment at the eave or in a valley – trapped moisture pushes synthetic underlayment loose, which leads to water channeling instead of draining. Common after summer storms in neighborhoods like College Park and Conway.
- Granule buildup in gutters paired with shingle edge curling – the shingle layer’s aging means water is getting under, and the underlayment is taking hits it was never designed to handle long-term.
- Soft spots when walking the roof – if your foot bounces or the roof feels spongy, the decking underneath has lost structural integrity. That’s a safety call, not a wait-and-see.

AfterTemporary Fix vs. Permanent Repair: What to Expect in Orlando
A tarp or patch will buy you a few days to a few weeks, but it won’t stop the real problem. In Orlando’s climate, a tarp secured to rotted decking just channels water to a different spot. When we arrive, we remove the failed underlayment in the affected area, inspect the decking beneath, and tell you honestly whether it’s sound enough to keep or needs to be cut out. We carry CDX plywood and Atlas-compatible underlayment on our trucks so we’re not making a second trip to the supply house mid-repair. The job is done the day we start, because water weight in a Florida rainstorm doesn’t wait for a restock.
DIY or Call Us?
Here’s the honest split. What you can safely do: get into the attic with a flashlight after a storm and look for dark, wet, or swollen decking. Mark the area with painter’s tape from the attic side so you can describe it to us clearly. What you should not do: pull up shingles and underlayment yourself on an Orlando roof in August. The decking gets hot enough to burn skin through gloves, unsecured sections flex dangerously underfoot, and if you miss sealing a seam, you’ve created a leak that wouldn’t have existed before. Deck work requires proper tie-offs and a crew that knows how to move on a 6/12 pitch without making it worse. If you see soft decking or water in the attic, call (850) 303-7235. We’ll walk the roof, show you what we found, and hand you a written price before anything comes off.
FAQs
Atlas synthetic underlayments like HP42 are rated for decades of service, but Orlando’s rain, heat, and humidity mean real-world lifespan lands between 15 – 25 years depending on attic ventilation and installation quality. Older felt products run 10 – 15 years here before they start breaking down. Call (850) 303-7235 and we’ll check what’s under your shingles.
Small, contained areas of underlayment can be patched, but if the damage covers more than a few square feet or the decking beneath is soft, you need a section replacement, not a patch. We’ll give you a direct answer based on what we see. Call (850) 303-7235 for a free estimate.
Most underlayment and deck repairs in Orlando are done in a single day, including the inspection, the deck replacement (if needed), and the underlayment install. Larger deck repairs may stretch to two days in worst-case scenarios. We show up in the window we gave you, not earlier and not later. Call (850) 303-7235 to talk it through.
Yes. We stock Atlas-compatible underlayment, CDX plywood, and the fasteners and sealants needed for a standard underlayment and deck repair on our trucks. If your warranty requires a specific Atlas SKU we don’t have on board, we’ll order it and schedule the repair once it lands. We also stock GAF, Owens Corning, and CertainTeed materials so you’re never stuck with one option. Call (850) 303-7235 to confirm parts for your model.
