What It Means to Be a Tamko Diamond Certified Contractor in Arizona

What It Means to Be a Tamko Diamond Certified Contractor in Arizona

You'll hear a lot of certification names from roofing contractors in the East Valley. Most are real. Most are also handed out to pretty much anyone who buys enough product and sits through a manufacturer seminar.

This one isn't like that.

All Storm Roofing + Construction holds the Tamko Diamond Certified designation. We're the only Tamko Diamond Certified roofing contractor in the state of Arizona. Not the only one in Gilbert, or in Maricopa County. In Arizona. The certification is verifiable through Tamko directly. We're not inventing the exclusivity here. It's just the reality.

What that means for you as a homeowner is worth understanding before you sign a contract with anyone.

What Tamko Diamond Certified Actually Requires

Tamko's contractor program runs in tiers. Most contractors who sell Tamko products are general certified. Platinum and Diamond sit above that. Diamond is the top.

Getting to Diamond isn't just about volume, though sustained volume is part of how it works. A contractor has to demonstrate consistent installation quality, maintain proper licensing and insurance, pass Tamko's installation knowledge requirements, and provide homeowner references that actually check out. It's not a badge you buy. It's one you earn through a track record, and then hold by continuing to meet the standard.

General certified contractors can sell Tamko shingles. That's about it. Platinum opens up better product access and some enhanced warranty terms. Diamond is where the top-tier warranty becomes available at all. No Diamond certification means no DiamondShield. Full stop.

The credential itself isn't the point, though. What Diamond unlocks is.

What DiamondShield Covers

The Tamko DiamondShield Enhanced Limited System Warranty is only available through a Diamond Certified contractor. Nobody else can register it for you. Not a Platinum contractor. Not a general Tamko installer. Only Diamond.

To qualify, the full system has to be installed. That means Titan XT shingles plus four qualifying Tamko accessories: underlayment, ice and rain barriers at valleys and penetrations, ridge cap, and starter strips. The whole thing, installed to Tamko's documented application standards. Swap out any component for a non-Tamko product and the DiamondShield registration is off the table.

Here's what you get when it's done right.

Materials: 50-year non-prorated Full Start. This is the number that separates DiamondShield from every other Tamko warranty. The standard Titan XT limited warranty carries a 10-year Full Start before prorating kicks in. DiamondShield stretches that to 50 years, non-prorated, covering both materials and labor for the life of the original owner's ownership on a single-family home. That gap exists only at the Diamond tier. No other Arizona roofer can offer it.

Workmanship: 25 years, manufacturer-backed by Tamko. This is the coverage that most homeowners don't think about until they need it. If an installation error causes a leak in year 14, a flashing detail that was slightly off or a valley that wasn't seated correctly, Tamko steps in and arranges the repair. You're not just hoping the contractor who installed your roof is still in business and willing to come back.

Wind: up to 160 mph. The qualifying install requires Tamko starter strips plus hip and ridge. When those are in place, the wind coverage is 160 mph. That's meaningful in a market where monsoon haboobs can hit 60 miles per hour and straight-line winds during summer storms regularly exceed 80.

Transfer: one time, within 20 years, for a $100 fee. A future buyer sees a roof with documented manufacturer coverage still running. In a real estate transaction in Gilbert or Chandler, that's an actual selling point, not a marketing bullet.

Registration: within 90 days of completion. We handle this. The warranty documentation comes directly from Tamko to you, not from us. Your coverage isn't tied to All Storm's continuity. If something happened to our company, Tamko still honors the warranty.

DiamondShield vs GAF Golden Pledge

This is a question we get regularly, and it deserves a straight answer.

The GAF Golden Pledge and the Tamko DiamondShield are peers. They're not identical, but at the top tier they're genuinely comparable. We're not going to claim Tamko beats GAF. That's not a true statement and it's not a useful one for you trying to make a real decision.

Here's how they actually compare.

Materials: Both cover 50 years, non-prorated. That's a tie.

Workmanship: DiamondShield covers 25 years of manufacturer-backed workmanship. GAF Golden Pledge covers 25 years on most shingles and 30 years on qualifying designer shingles. GAF wins slightly if you're installing designer shingles. For standard architectural shingles, they're equal.

Wind: Titan XT under DiamondShield carries 160 mph wind coverage with a qualifying install. Timberline HDZ under Golden Pledge carries approximately 130 mph. On wind, DiamondShield has an edge, which matters in the East Valley.

Contractor access: This is where Arizona is different. GAF Master Elite contractors, the tier required for Golden Pledge, represent about 2% of roofing contractors in North America. That's exclusive. But in a market the size of Phoenix, multiple Master Elite contractors operate. You have options.

Tamko Diamond Certified has one contractor in Arizona. All Storm.

So if you want 25-year manufacturer-backed workmanship coverage in the East Valley, both paths exist. One gives you a choice of contractors. The other gives you All Storm. Your decision should come down to which product and which crew you trust, not some manufactured claim that one manufacturer's shingle is categorically better than the other's.

We run Tamko because we believe in the system and because we put in the work to earn the highest tier. That's the honest version.

What the Warranty Covers and What It Doesn't

This is the part most homeowners skip, and then wish they hadn't.

A DiamondShield warranty is not a catch-all policy on your roof. It's a specific legal document with real coverage and real exclusions. Understanding the difference between what it covers and what it doesn't is how you avoid surprises.

Prorated vs. non-prorated: what it actually means. Non-prorated means that if a covered defect shows up in year 30, Tamko covers 100% of the replacement material cost. It doesn't shrink over time during the non-prorated period. Prorated means coverage that decreases as the roof ages. A standard asphalt warranty might cover 80% in year 11 and 20% in year 40. DiamondShield eliminates that erosion for 50 years. What you had on day one is what you still have in year 49.

Workmanship vs. material defects: they're different claims. A material defect is a manufacturing problem with the shingle itself. Granule loss beyond the normal aging rate, delamination of the shingle layers, premature cracking that isn't tied to installation. That's a material claim. A workmanship defect is an installation error. Flashing seated wrong at a pipe penetration. Nails driven outside the strike zone. Valley underlayment cut short. Those are workmanship claims. DiamondShield covers both, but through different mechanisms. The material coverage is Tamko standing behind its product. The workmanship coverage is Tamko standing behind All Storm's installation.

Storm and hail damage is not a warranty claim. This is the one that trips people up most. If a monsoon drops golf-ball hail on your roof and punches through shingles, that's a homeowners insurance claim, not a warranty claim. The warranty covers manufacturing defects and installation errors. It doesn't cover acts of nature. Your insurance policy covers storm damage. They're separate documents addressing separate events.

Ventilation failures are excluded. If your attic ventilation is inadequate and that inadequacy accelerates shingle degradation, the warranty won't cover it. This is why ventilation is part of our installation checklist on every job. A properly ventilated attic in Phoenix is not optional. Shingles cook faster in the desert than anywhere else in the country. The warranty assumes a correctly ventilated system.

The three claim paths, and when to use each. When something goes wrong with your roof, there are three doors:

The manufacturer warranty covers defects in the materials themselves, handled through Tamko. The workmanship warranty covers installation errors, handled through Tamko because the coverage is manufacturer-backed, not contractor-backed. And homeowners insurance covers storm, hail, wind, and weather damage, handled through your insurance carrier.

Each path has its own process. We help our customers figure out which door applies. That's part of what we do after the job is finished.

Why Workmanship Coverage Matters More Than Most Homeowners Think

Here's something we see on job after job in Gilbert, Chandler, and Mesa: the shingles aren't usually what fails.

Architectural shingles in Phoenix hold up for roughly 20 to 25 years under real desert conditions. Less in some cases, depending on ventilation, shingle grade, and sun exposure. The UV is brutal. The thermal cycling, cool mornings into 115-degree afternoons and back again, beats on everything. But the shingles themselves tend to be the last thing to give out.

What fails first is almost always installation. Flashing not seated correctly at a pipe boot or around a skylight. Nails driven outside the manufacturer's strike zone. Valley underlayment cut short. Ice and rain barrier not run far enough around a roof penetration. None of those are visible from the street. None of them show up at first inspection. They show up when monsoon rain comes in sideways on a July night.

A material warranty covers none of that. You're protected against manufacturing defects in the shingles. You're not protected against the installation mistake that let water in.

Twenty-five years of manufacturer-backed workmanship coverage changes what you're actually protected against. It's not a small upgrade over zero. It's a different category of protection.

The Part Homeowners Get Wrong

We hear this version of the objection regularly: "I just want good shingles. Why does it matter who installs them?"

Here's the direct answer. The shingles don't determine your workmanship coverage. The contractor's certification tier does.

Two roofers can buy the exact same Tamko Titan XT shingles from the same supplier, on the same day, for the same job size. One of them is Diamond Certified. One isn't. The homeowner who hired the certified contractor can receive DiamondShield coverage, with a 50-year non-prorated Full Start and 25 years of manufacturer-backed workmanship. The other homeowner gets the standard 10-year Full Start and zero workmanship coverage.

Same shingles. Completely different warranty outcome.

In Arizona, where the installation details, ventilation, underlayment placement, and flashing execution at every penetration are the variables that determine whether an asphalt roof lasts 15 years or 25, that difference isn't cosmetic.

East Valley Homes Get Hit Differently

Two things about roofing in Gilbert, Chandler, Mesa, and Queen Creek make workmanship coverage worth more here than in most other markets.

First is monsoon season. July through September, East Valley roofs take repeated hits from wind-driven rain, hail, and debris-loaded storms moving fast. A flashing detail installed slightly off stays dry through 364 dry days and then leaks on the night a haboob rolls through at 60 miles per hour. With DiamondShield in place, that leak is Tamko's responsibility to repair. Without it, the repair bill is yours.

Second is the UV and heat aging specific to the desert. Architectural shingles here age faster than in cooler markets because the granules that protect the asphalt matrix cook off faster under sustained triple-digit heat and intense UV. The right installation slows that process down. Proper attic ventilation, correct underlayment placement, tight flashing at every penetration. Installation quality is the variable. No amount of premium shingle compensates for corners cut on the install.
