A builder on your stoep

al­lowed for cur­ing. In the case of ce­ment tiles check that the tiles are hard and don’t break eas­ily. Check the tiles for hair­line cracks and chipped cor­ners be­fore they are fixed in place.

All roof­ing ma­te­ri­als are de­signed for spe­cific pur­poses, and are fixed dif­fer­ently in dif­fer­ent ar­eas, so check with your con­trac­tor that he has copies of the rel­e­vant fix­ing guides. Cer­tain ma­te­ri­als will not work right if fixed at the wrong pitch. Metal roof sheet­ing comes in dif­fer­ent thick­nesses – check that you are get­ting what you have paid for.

If your con­trac­tor is us­ing metal sheet­ing, in­sist that any cut­ting is done on the ground, in a shel­tered area. Loose fil­ings in your own or the neigh­bour’s swim­ming pool are not some­thing you want to deal with.

Spend a lit­tle more money on pre-coated sheet­ing which avoids the ne­ces­sity of paint­ing later. If you do choose an un­coated sheet, wait at least a year be­fore paint­ing; this al­lows na­ture to re­move all grease or other fac­tory coat­ings, which do not al­low a good bond for the paint.

Roofs do need to breathe, but open­ings at the edges should be closed with the rel­e­vant filler pieces for the ma­te­ri­als cho­sen. This will keep star­lings, squir­rels and other un­wanted guests out.

A fin­ished roof should be level, look neat and be free of sags, raised joints and, in the case of sheeted roofs, dents.

En­sure that the roof is checked by a suit­ably qual­i­fied per­son be­fore you ac­cept it and en­sure that you have a writ­ten guar­an­tee, un­der­writ­ten by the man­u­fac­turer where ap­pli­ca­ble.
