Tamko Underlayment & Deck Repair in Las Vegas, NV

Tamko Underlayment & Deck Repair: The Las Vegas Owner’s Guide

We stock and install Tamko-compatible underlayment and deck repair materials for Las Vegas homeowners, with most jobs running $1,200-$2,800 installed depending on square footage and deck condition. Same-day service is available when you call before noon, and we carry Tamko-approved Titanium UDL and Heritage series underlayment on every truck. Most Las Vegas owners discover this problem during our monsoon season, when water that should shed off the roof finds its way through compromised underlayment and into the attic through joints in the OSB or plywood deck below.

Which Tamko Models This Applies To

Tamko’s underlayment systems pair with their Heritage, Heritage Vintage, Heritage Woodgate, and Lamarite slate product lines, but the deck repair underneath matters more than the shingle brand on top. The Titanium UDL 30 and UDL 50 synthetic underlayments are the most common replacements we see in Las Vegas, particularly on homes built during the 2004-2009 construction boom where original felt paper has cooked past its useful life.

To identify what you’ve got, check the printed roll labels visible at the roof edge or in attic spaces, or look for the Tamko lot number stamped on shingle bundles stored in garages. The Titanium series runs 48 inches wide and installs with a 6-inch headlap in normal conditions, but Las Vegas code requires 8-inch laps in valleys and penetrations due to our intense thermal cycling. We also see some older homes with Tamko’s MetalWorks steel shingles over 30-pound felt; these decks often need localized repair where the felt has become brittle and cracked at fastener points.

We’re an independent service provider, not affiliated with Tamko, but we source OEM materials through authorized distribution. For deck repair, we match existing thickness exactly, 7/16-inch OSB or 15/32-inch plywood, never substituting a lesser grade that would void your remaining shingle warranty.

Signs Your Tamko Underlayment & Deck Repair Is Failing

• Water stains on ceiling drywall that align with roof valleys or vent penetrations. This pattern usually means the synthetic underlayment has torn at a seam or fastener line, letting monsoon runoff reach the deck below. In Las Vegas, UV exposure through missing shingles accelerates this breakdown faster than manufacturers rate for.
• Soft or spongy spots when walking the roof perimeter. OSB deck swells when it gets wet, then delaminates as our dry heat pulls moisture back out. By the time you feel give underfoot, the structural bond between plies has failed and the panel needs replacement, not just drying.
• Granule accumulation in gutters with no visible shingle damage. Excessive heat from a compromised underlayment layer cooks the asphalt shingle backing from underneath, causing premature granule loss while the top surface still looks intact. We see this especially on west-facing slopes in Summerlin and Henderson.
• Musty odors in attic spaces during summer afternoons. Even small underlayment breaches let enough moisture through to support mold growth on the deck underside, particularly where Las Vegas’s rare but heavy rains overwhelm inadequate laps or dried sealant.
• Visible underlayment curling or fishmouthing at roof edges. Titanium UDL has a high-temperature adhesive strip that can release when attic ventilation is poor; once the edge lifts, wind-driven rain enters directly. This is common on older homes with original soffit venting blocked by insulation.

Replacement Cost & What’s Included

What drives the range: deck accessibility (steep pitches in The Lakes or Spanish Trail neighborhoods take longer), how many penetrations need reflashing, and whether we find hidden rot once shingles come off. We quote the full number before starting, and that’s the number on the invoice. Our 90-Day Done Right Promise covers the workmanship, and Tamko’s material warranty runs concurrent where applicable.

DIY or Call Us?

There’s a safe middle ground here. A homeowner can check attic spaces for stains, photograph any visible underlayment branding from a stable ladder at the eaves, and verify gutter downspouts are clear. These checks help us diagnose faster when you call.

But removing shingles to expose underlayment, cutting deck panels, and properly integrating new Titanium UDL at code-required laps is not a weekend project. You’re working at height on material that was already compromised, which means the surface underfoot is less trustworthy than it looks. And matching the existing deck thickness wrong, even by 1/16 inch, creates a telegraph line that shows through new shingles within two seasons. We’ve fixed enough DIY attempts in Centennial Hills and Green Valley to know where the savings evaporate.
