70% of lawsuits have to do with what - ANS-Roofs
Sloped roof pitch? - ANS-> 3"/12"
Low sloped roof pitch? - ANS-< 3"/12"
Flat roof types - ANS-Built-up, SBS Modified, single ply
Steep roof types - ANS-Shingles, metal, tile, wood shingle
Roofing square dimension? - ANS-10 ft X 10 ft
Benefits of low slope roof - ANS-Less material, more usable space, easy to maintain, aesthetic
(hidden equipment)
Flat roof drains - ANS-Scupper drains, roof drain, gutter
Single ply roof types - ANS-Adheared, mechanical
Thermosetting - ANS-Will not adhear to each other w/ hear (EPDM)
Thermoplastic - ANS-Heat welded (becomes playable or bondable with heat) (TPD, PVC)
Types of water infiltration - ANS-Gravity, capillary, wind
Gravity induced water infiltration - ANS-Water travels down and sideways due to gravity
Capillary induced water infiltration - ANS-Adhesive/cohesive forces push water upwards
Wind induced water infiltration - ANS-Pressure differential waterproofing
Waterproofing types - ANS-Membranes, overhangs, joint seals, flashings
Membranes - ANS-Shed water, block water from penetrating (wind, gravity)
Overhangs - ANS-Provides a physical barrier from water (wind, gravity)
Joint sealants - ANS-Viscous liquid or tape to seal cracks (capillary, gravity)
Flashings - ANS-Impervious material, makes it difficult for water to enter (capillary, gravity)
