Umbalai-asphalt shingleluhlobo olutsha lweshiti engangeni manzi yophahla lwe-shingle eyenziwe ngezinto zokwahlukanisa, ezenziwe ngefayibha yeglasi ethambileyo njengomzimba wetayara kwaye zityibilizwe nge-asphalt eguquliweyo yomgangatho ophezulu. Ayinazo nje kuphela imibala etyebileyo, iimo ezahlukeneyo, ukukhanya nokuqina, ukwakhiwa okulula kunye nezinye iimpawu, kodwa ikwanazo nemisebenzi emihle yokuhombisa engangeni manzi, sisixhobo esitsha sokuhombisa esingangeni manzi esisetyenziswa kakhulu kuphahla oluthambekileyo ekhaya nakwamanye amazwe. Ifanelekile kuphahla olungangeni manzi oluthambekileyo olungaphezulu kwama-20°.

Nantsi inkcazo eneenkcukacha malunga nokwakheka okusisiseko kweiishingle ze-asphalt:

(3) Amasuntswana e-ore anombala: amasuntswana e-ore anombala kumphezulu we-asphalt shingle anokukhusela umphezulu we-asphalt elangeni ngqo, enze i-asphalt ingabi lula ukuyiguga, yandise ubomi benkonzo yethayile, ityebise umbala wemveliso, kwaye iphucule ukumelana nomlilo kwethayile yophahla.

(4) I-adhesive ezivalayo: umva wethayile ye-asphalt enemibala ene-tape yokuzincamathelisa. Emva kokuba ii-asphalt shingles ezinemibala zibekwe eluphahleni, i-adhesive ezivalayo ziya kusebenza phantsi kokukhanya kwelanga, nto leyo ebangela ukuba i-viscosity, ukuze ii-asphalt shingles ezinemibala ephezulu nesezantsi zidityaniswe ngokuqinileyo, ukuqinisekisa ukuthembeka kophahla.

(5) Izinto zokuzalisa (isanti ecolekileyo): ilitye lekalika lisetyenziswa kakhulu. Izinto zokuzalisa zinezibonelelo ezininzi kwithayile yophahla. Zinokuphucula ukusebenza kokungena kwamanzi kwemveliso, ziphucule ngokuphakathi ukumelana nemozulu kunye nokuqina kwethayile yophahla, kwaye zinciphise iindleko zemveliso.
