Roofing Steps

1. Ring beam and wall plates fixed.
2. Trusses or rafters set and braced.
3. Purlins fixed at the right spacing for your sheets or tiles.
4. Covering fixed with the right nails or screws and rubbers.
5. Ridges, valleys, flashing, then gutters.

Common Roofing Mistakes

• Untreated timber that termites eat.
• Wrong purlin spacing.
• Too few fixings, so sheets lift in wind.
• No gutters, so walls and foundations get wet.
