Warranty comparison: four separate promises
| Coverage | What it addresses | What to compare |
|---|---|---|
| Product defects | Manufacturing issues | Early protection, proration, labor and tear-off |
| Wind | Specified wind-related damage | Limits, duration, accessories and exclusions |
| Algae | Specified discoloration | Product variant, ridge requirements and remedy |
| Workmanship | Qualifying installation errors | Provider, term and contractor credentials |
A limited-lifetime product warranty is not a lifetime guarantee against leaks or storm damage. Enhanced coverage varies by contractor credentials, system components, property type and registration.
Compare early product protection
| Selected product or package | Published early protection |
|---|---|
| GAF System Plus and other qualifying enhanced packages | 50 years non-prorated for eligible single-family owners |
| IKO Dynasty / Nordic | 15-year Iron Clad |
| CertainTeed Landmark PRO | 10-year SureStart |
| Malarkey Highlander / Vista / Legacy | 10 / 15 / 20 years non-prorated |
| Owens Corning Standard / System / Preferred / Platinum | 10 / 50 / 50 / 50 years for single-family coverage |
| Atlas Pinnacle Pristine with Signature Select | 15 years Premium Protection |
| TAMKO Shield / ProShield / MasterShield / DiamondShield | 20 / 50 / 50 / 50 years Full Start for single-family structures |
These are manufacturer-defined periods, not equivalent promises. Enhanced packages have product, installation, registration and sometimes contractor-credential requirements. Read the exact warranty for covered costs, exclusions and what changes afterward.
IKO: standard and extended protection
IKO describes 15-year Iron Clad protection against manufacturing defects for its Performance products. Extended coverage is available through qualifying Select and Craftsman Premier contractors, subject to product and program requirements. It is not automatically included with every IKO roof.
Before signing, get the warranty name, applicable document, contractor eligibility and registration requirements in writing. Confirm what costs are covered and what changes after the initial protection period. Keep manufacturing defects separate from hail damage and installation workmanship.

Compare the quote, not just the shingle
| Include in every proposal | Keep the comparison fair |
|---|---|
| Roof preparation | Removal, decking and disposal |
| Water-management details | Underlayment, starter, flashing and penetrations |
| Finished system | Shingles, ridge and ventilation |
| Coverage and cost | Named warranties, registration and complete installed price |
Local supply, roof complexity and the included work affect price. We compare installed proposals rather than assigning a universal price or ranking every roof by brand alone.

TAMKO HailGuard: a separate hail-coverage question
HailGuard adds another UL 2218 Class 4 option. Its qualifying enhanced hail-warranty route is separate from the impact rating. Do not infer coverage from “Class 4” alone or assume that all contractor accounts can offer enhanced packages.
| Item | Verify in writing |
|---|---|
| Shingle | Exact product and version available locally. |
| System | Required starter, ridge, underlayment and installation details. |
| Coverage | Named warranty, property type, contractor eligibility and registration. |
| HailGuard | Separate hail provisions, covered damage and exclusions. |
