Roof Ventilation	Storage
When Roofing Shingles are used on heated buildings or insulated roofs, ventilation of the void space must be provided. For cold roofs ventilation should be at least equal to continuous strip 10mm wide (Ref. Bs 5534:2003).	Store shingles inside a ventilated area. Do not stack Square Butt Shingles more than 16 packs high and Hexagonal Shingles more than 14 packs high. Pallet loads must not be stacked directly upon each other.
	Store away from direct heat and sunlight
Additional Weather Considerations	In cold weather, store packs inside before use and gently warm before folding.
Whilst Roofing Shingles are designed for application on pitched roofs of 15 degree and over, in severe exposed locations it is recommended that the roof pitch should be a minimum of 30 degrees. In areas of very severe exposure such as coastal locations, use Square Butt Shingles only. The shingle gauge should also be reduced from 143mm to 130mm. Exposure categories as defined in BS5628: Part 3.	A roofing shingle pack weighs between 28.5kg and 32 kg depending on product type. The usual precautions should be taken when handling heavy objects
	Handling Handle Roofing Shingle strips carefully in cold weather to prevent cracking or breaking, and in hot weather to protect edges. Do not drop packs on their edges
