tearing off and old shingle roofThe City of Wellington New Zealand has the reputation as "the windy city", with gusts of 120km/hr (70mph) occuring on a frequent basis. The average "breeze" expected most days is around 18-35km/hr.

In fact there are very few areas within the Wellington Region, including Kapiti and Wairarapa, which do not fit into the Wind Zone  Classifications as "High" or "Very High"

Scie Construction Asphalt Shingle Applications are all classified as "very high wind uplift resistant".
We use either a 15lb felt or a self adhesive SBS bitumen sheet underlay, to provide a secondary waterproofing layer and  Large Head Galvanised Clouts (6 per shingle), hammered in by hand or for larger roof areas Galvanised or Stainless Steel Coil Roofing Nails by air powered Roofing Gun. We never use staples.
We also apply a spot of bitumen adhesive cement under every shingle tab, to provide a backup to the self ahesive strips.
Asphalt is one of the primary ingredients in roofing shingles. Its purpose is to provide the waterproofing integrity for the roof. Secondarily, the asphalt holds the colored granules in place and contributes to the overall strength of the shingle. Asphalt, which is derived from petroleum, contains the oils that provide ductility and pliability to the shingles.
