Discover everything you need to know about roofing and ceiling materials—from roof tiles and IBR/corrugated sheeting to SABS‑approved timber, ceiling boards, insulation and accessories—available at Build It DTM in Benoni.

1. Roof Tiles: Concrete & Steel Options

Concrete Roof Tiles

• Durable, fire-resistant and thermally efficient

• Styles include Marseilles, Broseley, Cordova, and concrete interlocking profiles

• Ideal for pitched roofs in Gauteng’s climate with longevity over 30–50 years

Steel Roof Tiles

• Lightweight yet strong, UV and wind-resistant

• Excellent for coastal or storm-prone areas when coated appropriately

2. Roof Sheeting: IBR & Corrugated Iron Profiles

IBR Sheeting (Inverted Box Rib)

• Strong, square-ribbed panels for excellent drainage

• Available in galvanised or Chromadek coatings

• Thicknesses between 0.3 mm – 0.5 mm

• Width: ~865 mm

Corrugated Roofing Sheets

• Traditional wavy profile; cost-effective and fast to install

• Good for sheds and residential builds

• Available in galvanised and Chromadek coatings, thickness 0.3 mm – 0.5 mm

• Width: ~865 mm

3. Structural Timber: SABS-Approved & S5 Kiln-Dried

We stock high-quality, SABS-approved structural timber that meets building code standards in South Africa. All timber is S5 kiln-dried, ensuring dimensional stability, reduced warping, and improved long-term performance.

Timber Sizes We Stock

• 38×38 mm

• 38×76 mm

• 38×114 mm

• 50×76 mm

• 38×152 mm

• 38×228 mm

Available Lengths:
All the above sizes are available in:
3 m, 3.6 m, 4.2 m, 4.8 m, 5.4 m, 6 m, and 6.6 m

These sizes are ideal for rafters, beams, fascia boards, trusses, and other structural roofing applications.

5. Insulation Materials: Thermal & Reflective

• Glass Wool Batts – Bulk insulation with R-values ~2 to 5 m²·K/W

• Reflective Foil Insulation (Sisalation) – Installed under roof sheeting to reduce radiant heat — recommended under IBR or Chromadek roofs to meet SANS 204 standard

High-quality thermal insulation in a compact roll, ready for efficient installation in your roofing or ceiling project.

6. Accessories & Roof Hardware

• Roof Underlay – Synthetic or bituminous moisture barrier beneath tiles or metal sheets

• Flashings & Ridge Capping – Ensures water-tight joints at ridges and edges

• Fasteners & Clips – Galvanised or coated screws with EPDM washers for IBR sheets

• Roof Battens & Purlins – 38×38 mm and 50×75 mm battens for tile support; steel purlins for sheeting

• Ventilation Solutions – Ridge vents, soffit vents to reduce condensation and prolong roof life

How to Choose the Right Materials

1. Consider Climate & Roof Type

For Gauteng’s summer sun and seasonal storms: choose IBR sheeting ≥0.5 mm or concrete tiles
Low-pitch structures favor sheeting profiles with hidden fasteners for wind resistance

2. Structural Integrity & Timber

Use SABS-approved, S5 kiln-dried timber to support heavy roofing materials like concrete tiles

3. Insulation for Energy Efficiency

Use bulk glass wool insulation combined with reflective foil to reduce heat gain and cooling costs

4. Ceiling Selection by Room Use

Use gypsum boards for living areas, cement fibre for moisture-prone zones, and PVC panels for washrooms
