Because of the natural characteristics of the high quality waterproofing material used, these shingles will be stiff in cold weather and flexible in hot weather. 1. These shingles are particularly tough, heavyweight shingles with a definitely rugged - looking appearance. They require additional effort to trim to fit on the roof. Curved blade utility knives are more effective than straight blade utility knives in cutting these shingles. Using a circular saw equipped with carbide- tipped blades is also effective. 2. Regardless of the tool used, always wear proper protective wear, i.e. gloves, eye protection, etc; follow all protection procedures and use tools carefully to prevent personal injury when working with these heavier products. 3. Do not drop bundles on edge or on other bundles to separate shingles. Do not load bundles across a hip or ridge. Do not bend bundles over shoulder for carrying. Premium weight may cause cracks at sharp bend points. 4. Handle carefully. Shingles can easily be broken in cold weather or their edges damaged in hot weather. 5. Store on flat surface, in a covered, ventilated area — maximum temperature 110 °F (43 °C). Do not store near steam pipes, radiators, etc., or in sunlight. 6. GAF -Elk does not recommend long -term storage of double stacked pallets. If double stacking is required for short periods, slip sheets of 1/2" (13mm) plywood cut to the pallet size are required between pallets to minimize damage. Long -term double stacked storage, especially in hot weather, can result in possible sticking, staining and distortion of the shingles in the lower layers of shingle bundles. 7. If shingles are to be applied during PROLONGED COLD periods or in areas where airborne dust or sand can be expected before sealing occurs, the shingles MUST be hand sealed. See "Wind Resistance /Hand Sealing" instructions. IMPORTANT: Repair leaks promptly to avoid adverse effects, including mold growth. Re- Roofing If old asphalt shingles are to remain in place, nail down or cut away all loose, curled or lifted shingles; replace with new; and just before applying the new roofing, sweep the surface clean of all loose debris. Since any irregularities may show through the new shingles, be sure the underlying shingles provide a smooth surface. Fasteners must be long enough to penetrate the wood deck at least 3/4" (19mm) or just through plywood. Follow above instructions for application. Note: Shingles can be applied over wood shingles if the surface can be made smooth enough. This may include cutting back old shingles at eaves and rakes, installing new wood edging strips as needed, and the use of beveled wood strips. Install #30 underlayment to maintain Class A rating.
