Owens Corning Preferred Roofing Contractor in Austin.

Owens Corning Preferred Contractor is a network tier Owens Corning describes as independent roofing contractors who meet high standards and strict requirements for professionalism and reliability, and the tier Owens Corning says is authorized to offer its extended System Protection and Preferred Protection limited warranties. A manufacturer certification describes training and warranty eligibility, not a warranty in itself. Zilker Roofing is a BBB Accredited Business and is Fully Insured — General Liability & Workers' Compensation (certificate of insurance available on request). Owens Corning publishes its own contractor profile for Zilker Roofing, linked below.

We install many types of shingles, but Owens Corning stands out for: Beautiful design and color options (ask about Duration® and Oakridge® lines). Advanced technology like patented SureNail® Technology—with Triple Layer Protection® in the nailing zone. We also work with GAF, Malarkey, and other manufacturers to ensure every homeowner gets the product that fits their needs.

Each Owens Corning line below is installed by Zilker Roofing. Supreme: Owens Corning's 3-tab. Oakridge: Entry-level architectural (laminate) shingle. TruDefinition Duration: Flagship architectural laminate shingle, UL 2218 Class 3 (FM 4473 Class 3). Duration Designer: Enhanced architectural shingle, UL 2218 Class 3. Duration MAX: thick architectural laminate, UL 2218 Class 3. Duration STORM: Class 4 impact-resistant architectural shingle, UL 2218 Class 4 (FM 4473 Class 4). Duration FLEX: Class 4 impact-resistant architectural shingle (SBS-modified), UL 2218 Class 4 (FM 4473 Class 4). Duration COOL: Solar-reflective (cool roof) architectural shingle, UL 2218 Class 3. Which line fits a specific roof is a job-by-job determination made after an inspection.

Owens Corning's Class 4 offerings are the TruDefinition Duration STORM and FLEX lines, both rated UL 2218 Class 4 (FM 4473 Class 4) and both installed by Zilker Roofing. They reach that rating with different construction. Duration STORM: Unlike standard shingles, TruDefinition® Duration STORM® impact-resistant shingles feature patented WeatherGuard® Technology. Owens Corning lists its technologies as WeatherGuard® Technology (integrated polymeric backing), SureNail® Technology, non-SBS, and states that Corresponding Hip & Ridge Shingles are required to complete UL 2218 Class 4 Impact Resistant Roof System for warranty coverage. Duration FLEX: TruDefinition® Duration FLEX® shingles are made with a proprietary blend of SBS polymer modified asphalt. In Owens Corning's words, the rubberizing effect of the uniquely blended SBS modified asphalt makes the shingle pliable and gives them greater flexibility and enhanced durability and toughness, especially under intense storm conditions. A UL 2218 class is a laboratory impact test result, not a promise about hail. A homeowner comparing quotes can ask each bidder which specific line is being priced and whether that line carries the UL 2218 Class 4 classification on its own product literature.

Zilker Roofing installs both brands. It is an Owens Corning Preferred Contractor, it holds Malarkey's Emerald Pro contractor credential, and most of the roofs it installs are Owens Corning; Vista is the Malarkey line it installs most often. The differences, as each manufacturer states them: Impact rating — TruDefinition Duration is UL 2218 Class 3 (FM 4473 Class 3); Vista is UL 2218 Class 4 (effective on installs from January 1, 2023), and Owens Corning's Class 4 offerings are the TruDefinition Duration STORM and FLEX lines. Asphalt — Vista is made with NEX® Polymer Modified (Rubberized) Asphalt, and within the Duration Series, TruDefinition® Duration FLEX® shingles are made with a proprietary blend of SBS polymer modified asphalt. Nailing zone — Duration has patented SureNail® Technology—with Triple Layer Protection® in the nailing zone; Vista has The Zone® patented nailing area. Warranty — Owens Corning states a Limited Lifetime Warranty for Duration, with wind rated Up to 160 MPH (condition: TPRS components + starter on eaves and rakes); Malarkey publishes a Limited Lifetime Shingle Warranty · 110 mph (177 kph) Limited Wind Warranty · 130 mph (209 kph) Enhanced Wind Warranty available for Vista. These are each manufacturer's own published figures, and the manufacturer's current product and warranty pages are the authority on them. Contractor program — Owens Corning Preferred is the tier Owens Corning says is authorized to offer its extended System Protection and Preferred Protection limited warranties, while Malarkey ties its enhanced Pro and Premium warranties to complete Secure Choice systems installed by contractors certified through its residential contractor program. A brand name on a quote identifies a product family, not a price or a quality verdict — lines within one family span tiers, and installation quality is independent of brand. Two quotes naming different brands can describe comparable tiers — or very different ones — so the useful question is which tier within a family a quote specifies.

The workmanship warranty and the shingle warranty are separate. Roof replacements carry Zilker Roofing's 5-year workmanship warranty, separate from the manufacturer's material warranty. Owens Corning and Malarkey shingles carry limited-lifetime coverage against manufacturing defects, with enhanced non-prorated terms available on a full manufacturer system. Owens Corning's own definition of lifetime coverage is that, for an owner of a single family detached home, the warranty is in effect for manufacturing defects as long as you own your home, with reduced coverage for non-single-family or commercial structures. Owens Corning Preferred is the tier Owens Corning says is authorized to offer its extended System Protection and Preferred Protection limited warranties; availability of an extended warranty depends on which components are installed together and on the installing contractor's standing with the manufacturer. A manufacturer's warranty is the manufacturer's, on the manufacturer's terms — registration, matched components and installation conditions decide what is covered, and a tier name is not a quality verdict on any individual roof. We document what is covered in writing.

Owens Corning markets an integrated asphalt roof as the Total Protection Roofing System, framed by three functions: seal, defend, and breathe. From the deck up, the sealing layers are synthetic underlayments (the ProArmor and DeckDefense lines) and self-adhered ice and water barriers in the WeatherLock line for eaves, valleys, and penetrations. The defending layers are the shingle courses: a Starter Strip Plus course at the eaves and rakes, the field shingles, and matching hip and ridge shingles from the ProEdge, DuraRidge, DecoRidge, RIZERidge, and ImpactRidge lines capping the peaks. The breathing layer is balanced attic ventilation through the VentSure family of ridge and intake vents. Generic components such as drip edge and flashing remain part of any complete installation alongside the branded layers. A brand-matched system is about warranty eligibility and components designed and tested to work together; which layers a specific roof requires is a job-by-job determination.
