Tamko Underlayment & Deck Repair Nationwide

Tamko Underlayment & Deck Repair: The Sacramento Owner’s Guide

We stock Tamko-compatible underlayment and deck repair materials in Sacramento, and most underlayment repairs or replacement jobs run between $650 and $2,400 installed, depending on how much decking has to come out and what the roof pitch looks like. We can usually get a crew to your house the same week you call us at (279) 348-3049. The way most Sacramento homeowners find out their Tamko underlayment has failed is simple: water shows up on the ceiling after a heavy rain, or you spot a shingle that’s lifted and see felt or synthetic underlayment that looks shredded, brittle, or torn underneath it.

Underlayment is the water-shedding layer that sits between your roof deck (the plywood or OSB sheathing) and your shingles. When it fails, water gets to the decking. And once decking starts to rot, the repair stops being about a roll of felt and starts being about plywood replacement, which is where the price climbs. Greg Holloway has walked hundreds of these jobs in Sacramento, from Land Park to Natomas, and the pattern is always the same: the underlayment was never the problem until the shingles above it aged out or the flashing let go.

Which Tamko Models This Applies To

Tamko builds their shingle lines around a few core series: Heritage, Heritage Vintage, Heritage Woodgate, Elite Glass-Seal, and Titan XT. The underlayment below those shingles is not model-specific in the way a starter strip or a ridge cap is, but the right deck repair and underlayment choice still depends on what’s already on your roof and how it was fastened. If you have a Tamko roof installed in the last ten years, chances are the original contractor laid down either a Tamko synthetic underlayment or a #30 or #15 felt product, depending on what the bid allowed.

The compatibility gotcha most Sacramento homeowners run into is this: Tamko’s warranty language assumes the underlayment meets their installation specs, meaning if a repair is done with a mismatched or bargain underlayment, any remaining manufacturer warranty on the shingles is effectively void. We don’t take that risk. We match the underlayment weight and type to the original installation spec, and we use Tamko-branded or Tamko-spec equivalent products from our supplier network. We’re an independent service provider, not a Tamko company store, which means we can also pull from GAF, Owens Corning, and CertainTeed stock when that’s the better fit for your roof and your budget.

Signs Your Tamko Underlayment & Deck Repair Is Failing

• Water stains on ceilings or attic rafters after rain. This is the classic symptom. Underlayment that has torn, cracked, or pulled away from the deck lets water through, and gravity does the rest.
• Shingles that lift or flap in wind. If the underlayment beneath has deteriorated, shingles lose their secondary water barrier. Even if they re-seat, the seal between shingle and underlayment is gone.
• Granules in the gutter with a waxy or fibrous residue. That residue is often bits of degraded felt or synthetic underlayment washing down. It means the layer under the shingles is breaking apart.
• Soft spots or spongy feel on the roof deck. When you press a foot in certain places and feel give, the decking has absorbed water. That’s past underlayment failure and into deck repair territory.
• Visible underlayment at the eaves or rake edges. If you can see torn, brittle, or sun-bleached underlayment at the roof edges, it has been exposed to Sacramento’s UV and heat too long. It’s only a matter of time before water finds its way in.

Replacement Cost & What’s Included

For a typical Sacramento single-story home, a targeted Tamko underlayment repair with deck patching runs $650 to $1,800. A full underlayment replacement on a section of roof, including tearing off shingles, replacing decking as needed, and re-shingling, lands between $1,400 and $2,400 for most roofs under 20 squares. Steep pitches, two-story access, extensive deck rot, or a full re-deck all push the number higher, and we’ll tell you exactly where the money goes before a nail is driven.

Every quote from us is a fixed written price. You’ll see the cost for materials, labor, decking replacement per sheet, and disposal, line by line. No change orders for “unforeseen conditions” once work starts. We write the price down, you approve it, and that’s the number on the invoice. Every repair is covered by our written guarantee, and if the repair fails inside the guarantee period, we come back at no charge. That’s the 365-Day Done Right Promise, and it’s in writing before the crew leaves your property.

DIY or Call Us?

You can safely do a visual check from the ground or from a ladder at the eaves: look for lifted shingles, exposed underlayment, water stains on the underside of your roof deck in the attic, or granules in your gutters. What you should not do is walk a roof with failed underlayment to try to peel back shingles and inspect the deck. The moment you start pulling shingles in Sacramento’s summer heat, you risk cracking adjacent shingles, tearing the underlayment further, and creating a leak where there wasn’t one. And decking that is water-softened is a fall risk that no homeowner should be on top of.

Underlayment and deck repair is not a weekend project. It requires lifting shingles without breaking the seal, cutting out damaged deck sheathing, matching the underlayment spec, and re-fastening everything so the roof stays watertight. If any of that is done wrong, the result is a roof that leaks faster than the one you started with. We tell you the price before we touch your roof, every time, no exceptions. Call (279) 348-3049 and Greg or one of our techs can walk the roof, give you the specific number, and have the repair scheduled the same week.
