Malarkey Legacy and Windsor Scotchgard offer 20 years of full non-prorated coverage -- the longest available from any major manufacturer. GAF and Owens Corning offer 10 years.

Malarkey
Our primary strategic focus. Every Malarkey architectural shingle uses NEX polymer-modified rubber asphalt -- tougher, more flexible, and more impact-resistant than standard asphalt. The Right Start period (full non-prorated coverage) is longer than any competitor at any tier.
Standard (any contractor)
Any Malarkey shingles -- no certification required
Lifetime limited against manufacturing defects. Non-prorated Right Start period of 10 to 20 years depending on product. Transferable to new owner within 30 days of title transfer.
| Product | Tier | Impact | Wind | Algae | Right Start | Key Feature |
|---|---|---|---|---|---|---|
| Highlander | Arch / Entry | Class 3 | 130 mph | 10 yrs AR granules | 10 yrs | Entry point to NEX polymer-modified asphalt. 210 lbs per square. Class 3 impact rating. |
| Vista / Vista AR | Arch / Mid | Class 4 | 130 mph | 12-15 yrs AR granules | 15 yrs | Step up to Class 4. 225 lbs per square. Longer Right Start than Highlander. Strong choice for insurance restoration. |
| Legacy | Arch / Premium | Class 4 | 130 mph | 12-15 yrs AR granules | 20 yrs | 20-year Right Start with AR granule algae protection. Same impact rating as Legacy Scotchgard at a lower price point. |
| Legacy Scotchgard | Arch / Premium | Class 4 | 130 mph | Lifetime (3M Scotchgard) | 20 yrs | Lifetime algae protection via 3M Scotchgard treatment. 20-year Right Start -- the longest full coverage on the market. |
| Ecoasis Premium | Arch / Eco Premium | Class 4 | 130 mph | 20 yrs | 20 yrs | Class 4 plus cool-roof rated. Highest reflectance in the Malarkey line. GreenCircle certified. Best sustainability story from any major brand. |

The Right Start comparison: Legacy and Legacy Scotchgard give you 20 years of full non-prorated coverage. GAF and Owens Corning give you 10. If a Legacy roof fails in year 14 due to a manufacturing defect, you get full replacement value. With GAF or OC at year 14, you get a depreciated payout. That is a real dollar difference -- and it matters most when you need it most.
The eco story: Malarkey incorporates recycled rubber tires and plastic bags into every shingle. Their smog-reducing granules break down nitrogen oxides using sunlight -- actively cleaning the air. GreenCircle certified.

Selling your home? All three brands allow full warranty transfer to the new owner. Malarkey requires the new owner to register within 30 days of the title transfer date -- if this window is missed, the warranty voids entirely. GAF and Owens Corning transfers are simpler. Perfect Circle will provide all documentation needed to support the transfer at the time of sale.
