Tamko Flashing Replacement Nationwide

Tamko Flashing Replacement: The Los Angeles Owner’s Guide

Most Tamko flashing replacements in Los Angeles run between $280 and $550 installed, and we stock the common Tamko profiles on our trucks for same-day completion. We match your existing Tamko system by series, pitch, and color so the new metalwork integrates cleanly with your shingles. Homeowners usually spot trouble after a hard rain, when a water stain blooms on a ceiling near a chimney, vent, or wall intersection where the flashing should be sealing.

Which Tamko Models This Applies To

Tamko flashing isn’t one-size-fits-all. The profile and gauge you need depend on which Tamko shingle system is on your roof. Heritage series, Heritage Vintage, Heritage Woodgate, and Titan XT all use slightly different base-flange widths and sealant-channel designs. The Heritage line carries a 1.5-inch base flange on standard step flashing, while Titan XT’s higher wind rating requires a heavier 26-gauge galvanized or aluminum piece with a deeper kickout leg.

Check the shingle label in your attic or garage, or look for the Tamko stamp on exposed metal near a vent pipe. If you can’t locate it, we measure the exposed flange, the pitch of your roof, and the clearance to the wall or penetration. That’s how we confirm compatibility before we order anything.

We’re an independent service provider, not affiliated with Tamko. We source OEM Tamko flashing where it makes sense, but we also carry quality aftermarket equivalents that meet the same ASTM standards, often at a lower parts cost. For most Los Angeles homeowners with Heritage or Titan XT systems, the aftermarket piece performs identically. The exception is color-matched painted flashing on Vintage or Woodgate jobs, where the OEM finish blends noticeably better.

Signs Your Tamko Flashing Replacement Is Failing

• Rust streaks running down the wall or chimney brick. Tamko’s galvanized step flashing carries a factory coating, but Los Angeles marine air, especially in beach-adjacent neighborhoods like Venice or San Pedro, accelerates corrosion at cut edges. Once rust appears, the metal is thinning and will soon leak.
• Water stains on interior ceilings near roof-wall joints. This usually means the counterflashing seal has separated from the masonry or the step flashing has pulled free from the wall. In older Los Angeles homes with stucco exteriors, settling cracks let water behind the flashing even when the metal itself looks fine.
• Lifted or curled shingles at the flashing edge. Tamko’s self-sealing strip should bond the shingle to the flashing flange. Heat cycling in the San Fernando Valley weakens that bond over time, creating a gap that funnels water straight to the deck.
• Visible gaps where caulk or sealant has cracked away. Many homeowners try to band-aid this with roof cement, but the real fix is removing the old flashing and reinstalling with fresh underlayment. Caulk over failing metal just traps moisture.
• Granule buildup in gutters below a chimney or vent. This signals shingle movement at the flashing, often from improper nailing or a flange that’s too short for the pitch. The abrasion wears both the shingle and the water barrier underneath.

Replacement Cost & What’s Included

Your total depends on how many feet we’re replacing, whether we need to remove and reset shingles, and if the underlying deck is damaged. We deliver a written price before any work starts, and that number is the number on the invoice. No change orders, no surprises. Every flashing replacement carries our 365-Day Done Right Promise, in writing, included with the job. If it leaks, we come back and fix it at no charge.

DIY or Call Us?

There’s a safe middle ground here. You can walk the perimeter with binoculars and spot rust, lifted shingles, or missing sealant. You can check your attic after rain for active dripping. What you shouldn’t do is pull shingles or pry flashing yourself. Roof work at height is genuinely dangerous, and disturbing a sealed assembly without knowing how to reintegrate the underlayment often turns a $300 repair into a $1,200 deck replacement.

We’re background-checked, uniformed, and you’ll know who’s arriving before they pull in. You can track our live arrival time, and we send before-and-after photos by text along with your digital invoice. Call (325) 246-5075 to schedule your free estimate.
