GAF Timberline AS II

What This Service Involves

Timberline AS II pairs GAF's proven architectural laminate design with a Class 4 impact rating, the highest tier in the standard impact test. The reinforced construction helps the shingle resist cracking from hail and falling limbs, which can matter during Northwest windstorms that bring branches down onto roofs. It keeps the dimensional, wood-shake styling homeowners expect from the Timberline family. Because many insurers offer premium considerations for Class 4 roofing, AS II can be a smart long-term choice. It suits homes in wooded Puget Sound settings where debris impact is a real concern.

Benefits

Class 4 impact rating for strong resistance to hail and debris; May qualify for insurance premium considerations in some policies; Familiar Timberline architectural styling and color range; Durable construction for wooded, storm-exposed PNW lots; Algae-resistant granules to fight climate-driven streaking

Our Process

1) Tear off the old roof and check the deck for soft spots and moisture; 2) Apply ice-and-water shield and synthetic underlayment across critical areas; 3) Install the reinforced AS II shingles with correct fastening for impact performance; 4) Finish ridges and seal every penetration and flashing detail

What Affects the Cost

Roof size, pitch, and layout complexity; Impact-resistant shingles cost more than standard laminate; Extent of deck repairs found during tear-off; Local tree cover and debris exposure influencing the upgrade decision; Documentation needs for potential insurance considerations

Best Time of Year

AS II installs in any season locally, and scheduling ahead of fall and winter storm season adds protection before the worst weather arrives.
