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