Weatherproofing membrane having high traction surface

A method of making a membrane having a high traction polymer surface, said method comprising the steps of:

• providing a membrane including at least one facer sheet;
• hot mixing a quantity of amorphous polyolefin with a quantity of low molecular weight polyethylene to form a non-bituminous polymer blend;
• and
• applying said polymer blend to a plurality of separate and distinct regions of an upper side of said facer sheet of said membrane.

A weatherproofing membrane comprising:

• at least one facer sheet having an upper side and a lower side, said at least one facer sheet being formed of a weatherproofing material;
• at least one layer of a high traction polymer blend disposed on a plurality of separate and distinct regions of said upper side of said at least one facer sheet, said polymer blend comprising a mixture of low molecular weight polyethylene and amorphous polyolefin, wherein said plurality of separate and distinct regions including said high traction polymer blend provides a higher traction than said weatherproofing material of said facer sheet;
• and
• at least one layer of modified asphalt disposed on at least a portion of said lower side of said facer sheet.
