Tamko Flashing Replacement Nationwide

Tamko Flashing Replacement: The Santa Clarita Owner’s Guide

Tamko flashing replacement in Santa Clarita typically runs $285 – $640 installed, depending on which flashing points failed and how tall the roof is. We carry Tamko-compatible flashing on our trucks for most standard homes, so a single repair visit usually gets everything sealed the same day. The way most homeowners find out their flashing has failed is not dramatic. You spot a brown stain on the ceiling after a Santa Clarita winter rain, or you notice shingles lifting near a chimney. The actual fix is often fast, but ignoring it is how a $300 flashing job becomes a $4,000 drywall and insulation repair.

Which Tamko Models This Applies To

Tamko flashing itself is not tied to one shingle line the way some homeowners assume. Whether you have Tamko Heritage architectural shingles, Titan XT, or the newer StormFighter FLEX series on a Santa Clarita home, the flashing components are largely the same family of products. What changes is the adjoining surface: a chimney flashing kit on a steep Stevenson Ranch two-story is a different installation than step flashing along a one-story Valencia addition.

Here is the compatibility gotcha most people do not know: Tamko’s step flashing uses standard 10-inch by 8-inch pieces with a 3-inch reveal, almost identical to what GAF and Owens Corning supply. That means a quality galvanized or G-90 coated aftermarket step flashing works fine with Tamko shingles in most cases. But Tamko’s valley metal and chimney saddle flashings are pre-formed to Tamko’s specific bend profiles, and a universal piece often sits wrong. We keep OEM-profile Tamko valley metal on hand and use aftermarket only where it truly fits. If you can still see the package label from your original install, it will say the profile code near the barcode. Send us a photo before the visit and we will match it.

Signs Your Tamko Flashing Replacement Is Failing

• Water stains on ceilings or walls after rain. This is the classic first sign of flashing failure in Santa Clarita homes, especially where stucco meets the roofline. The water travels along framing first, so the stain often appears a few feet from the actual leak.
• Lifted shingles near the chimney or wall edge. Tamko shingles are thick and hold well, but when the flashing underneath separates from hydrostatic pressure or age, the shingle edge above it starts to curl. That curl is a sign the flashing, not the shingle, is the problem.
• Granules accumulating in the gutter at one specific spot. A leaking flashing point erodes the shingle’s asphalt layer faster than the rest of the roof. If one corner of the roof deposits more granules than any other, the flashing below is usually the cause.
• Dark streaks or moss on stucco where the roof meets the wall. In Santa Clarita’s hot, dry months, a small flashing gap lets moisture out and it dries fast. But the mineral salts left behind create a dark line, which means water has been getting in for a while.
• A rust-colored drip or streak running down from a plumbing vent boot. This is the part that almost always fails first. Tamko vent boots use a neoprene collar that degrades fast under the high-desert sun we get in Santa Clarita, especially on south and west exposures.

Replacement Cost & What’s Included

Most Tamko flashing replacements in Santa Clarita fall between $285 and $640 installed. The price depends on three things: which flashing points failed, the roof pitch, and the story height. A single vent boot replacement on a one-story Valencia rambler runs on the low end, around $285 to $380. A chimney flashing repair with new counterflashing on a two-story Saugus home runs $450 to $640. Step flashing along a wall is priced by the linear foot, usually $18 to $28 per foot installed.

Every quote includes the part, the removal of the old flashing, installation, new sealant where needed, and the labor to reseat surrounding Tamko shingles. You also get our 365-Day Done Right Promise on every repair, in writing: if the repair fails within a year, we correct it at no charge. And the written price Dylan Pace hands you is the number on the invoice. No change orders because we found a surprise. If something unexpected does come up once we see the deck, we stop, send a photo, and agree on the new number before proceeding.

DIY or Call Us?

There are two ends of this conversation in Santa Clarita. On the flat, one-story parts of the roof, a homeowner who is comfortable on a ladder can definitely check whether the caulking around a vent boot is cracked, or whether step flashing has pulled away from the wall. That is information gathering. It costs nothing except a careful climb. But actually replacing flashing is where DIY goes sideways, and not because of tools. The danger is roof pitch. Most Santa Clarita neighborhoods we work in, especially Stevenson Ranch and parts of Newhall, have 6/12 to 8/12 pitches. That is steep enough that a momentary reach turns into a slide. And a flashing repair that is not sealed and re-bedded correctly just leaks again in the next heavy rain, which costs the homeowner twice.

If you are on a ladder and the roof feels steep, stop. Snap a photo of the failure with your phone and call us at (661) 219-7793. We will tell you what we are seeing over the phone, and give you a written replacement quote before we start. Every estimate we hand you is one we’d be comfortable signing twice.
