In Nairobi and across Kenya, roofs are one of the most critical parts of any building, yet they are also among the most vulnerable to weather, age, and structural stress. From simple residential houses to large commercial warehouses, a leaking or damaged roof can lead to water damage, mould, ruined interiors, and even structural weakening over time. At imperialappliances.co.ke, we go beyond home appliances—we also provide professional roof repair services covering a wide range of common and specialized roof types used in homes, estates, shops, and industrial buildings. This article provides a comprehensive list of roof types that we repair, explains what each type is made of, and highlights typical problems we handle.

Why Roof Repair Matters in Nairobi

Nairobi’s climate features seasonal heavy rains, strong sun, and occasional hailstorms, all of which take a toll on roofing materials. A poorly maintained roof can develop leaks, rust, broken tiles, or loose fasteners, which then translate into water dripping into ceilings, damaged walls, and spoiled goods or equipment inside. Delaying roof repairs often leads to much more expensive ceiling, wall, or structural repairs later.

At imperialappliances.co.ke, we treat roof repair as a preventive maintenance service as well as an emergency fix. By identifying and repairing faults early—such as loose or missing panels, corroded metal, or cracked tiles—we help property owners extend the life of their roofs and avoid sudden failures during the rains.

Comprehensive List of Roof Types That We Repair

Below is a detailed overview of the main roof types we repair in Nairobi and surrounding areas, grouped by material and design:

1. Corrugated Metal Roofs (Iron/Aluzinc)

Corrugated iron and aluzinc sheet roofs are among the most common in Nairobi, especially in low‑cost housing, guardhouses, and small shops.

  • Typical faults: Rusting, loose or missing screws, dented sheets, leaks at joint lines, or water pooling at low‑points.

  • Our repairs:

    • Replacing rusted or badly damaged sheets.

    • Re‑sealing joints with silicone or butyl tape.

    • Tightening or replacing loose screws and ridge caps.

    • Installing additional gutters or downspouts where needed.

2. Steel Roof Trusses with Metal Sheeting

These roofs combine a steel‑frame truss structure with metal sheet covering, commonly used in shops, garages, workshops, and warehouses.

  • Typical faults: Loose bolts/joints, sagging trusses, leaking sheet joints, or rust on the metal sheathing.

  • Our repairs:

    • Inspection and tightening of truss connections.

    • Replacement of corroded or damaged truss members where safe.

    • Re‑sealing or replacing leaking metal sheets.

3. Tile Roofs (Concrete and Clay Tiles)

Tile roofs are popular in mid‑range and high‑end homes, especially in estates and gated communities.

  • Typical faults: Broken or cracked tiles, moss or algae buildup, blocked gutters, and leaks at the ridge or hips.

  • Our repairs:

    • Replacing broken or missing tiles with matching types.

    • Cleaning and re‑sealing ridge caps and valley joints.

    • Checking gutter integrity and slope for proper water flow.

4. Terracotta and Ceramic Tile Roofs

Terracotta and ceramic tiles are often used for their aesthetic appeal and durability.

  • Typical faults: Fragile tiles that crack easily, slipped tiles, or water seepage at joints.

  • Our repairs:

    • Careful removal and replacement of damaged tiles.

    • Inspection of underlay and batten fixings.

    • Re‑sealing exposed joints and flashings.

5. Concrete Slab Roofs

Concrete slab roofs are common in modern apartments, duplexes, and some commercial buildings.

  • Typical faults: Cracking, leaks at expansion joints, failed roof screed or bonding, or poor waterproofing layer.

  • Our repairs:

    • Crack injection and sealing with polymer‑based compounds.

    • Re‑application of waterproof membranes where needed.

    • Inspection of drainage outlets and adjoining walls.

6. Green (Living) Roofs and Vegetated Roofs

Less common but increasingly used in modern eco‑friendly buildings, these roofs have soil and plants growing on top of a waterproof layer.

  • Typical faults: Root damage to waterproof membranes, blocked drainage, soil‑bed overloading, or weak support.

  • Our repairs:

    • Assessment of the waterproofing layer and root‑barrier integrity.

    • Diverting or replacing drainage outlets.

    • Thinning or re‑supporting the vegetation layer where necessary.

7. Asbestos (AIB) or Eternit‑Style Roof Sheets

Many older buildings still have asbestos‑or asbestos‑cement roof sheets, which are now known health hazards.

  • Typical faults: Brittle, cracked sheets, broken joints, and loose fixings.

  • Our repairs:

    • Safety‑first handling and replacement with safer materials such as modern metal or plastic sheets.

    • Proper disposal planning and ensuring the surrounding area is protected during work.

8. PVC and Plastic Roof Sheets

PVC and other plastic roof sheets (e.g., polycarbonate or PVC‑coated) are used in greenhouses, carports, and modern canopies.

  • Typical faults: UV‑related brittleness, cracking, or overheating deformation.

  • Our repairs:

    • Replacing damaged or discolored sheets.

    • Adjusting supports and spacing to prevent sagging.

    • Sealing edges and joints with compatible sealants.

9. Shingle Roofs (Asphalt or Bituminous Shingles)

Though less common in Kenya, some imported or contractor‑built houses use shingle roofs.

  • Typical faults: Blistering shingles, wind‑blown or curled shingles, leaks at ridges or valleys.

  • Our repairs:

    • Replacing damaged or missing shingles.

    • Re‑sealing edges and flashings.

    • Checking under‑shingle felt and ventilation.

10. Metal Standing Seam Roofs

Used in modern commercial and industrial buildings, standing seam roofs have vertical metal panels with raised seams.

  • Typical faults: Loose or damaged seams, leaking at joints, corrosion along the edges.

  • Our repairs:

    • Re‑sealing or re‑crimping seams.

    • Replacing damaged panels or sections.

    • Checking clip fasteners and expansion allowance.

11. Skylight and Roof Light Panels

Skylights and plastic or glass roof panels are often integrated into metal or slab roofs for natural lighting.

  • Typical faults: Cracked or foggy panels, leaking around frames, or damaged seals.

  • Our repairs:

    • Replacing broken or yellowed panels.

    • Re‑sealing frames and flashing details.

    • Ensuring proper drainage around the opening.

12. Cool Roof and Reflective Roof Systems

Some modern buildings use white‑coated or reflective roofs to reduce heat absorption.

  • Typical faults: Peeling reflective coating, pooling water, or cracks in the protective layer.

  • Our repairs:

    • Cleaning and re‑applying reflective coating where appropriate.

    • Restoring the underlying waterproofing layer.

    • Ensuring proper slope and drainage.

13. Flat Roof Systems (Bitumen, PVC, or EPDM Membranes)

Flat roofs are common in commercial buildings and some modern residential blocks.

  • Typical faults: Punctures, blisters, poor drainage, or ponding water.

  • Our repairs:

    • Patching or replacing sections of the membrane.

    • Re‑establishing positive drainage slope.

    • Re‑sealing expansion joints and edges.

14. Roof Terraces and Solar‑Panel Roofs

Terrace roofs and roofs with mounted solar panels require extra care to avoid leaks around the penetrations.

  • Typical faults: Leaks around PV mounts, failed flashing around skylights or vents, or worn‑out waterproof layers.

  • Our repairs:

    • Reflashing around mounts and penetrations.

    • Repairing or replacing the waterproof membrane without disturbing the solar structure.

    • Checking the structural load capacity and drainage.

15. Traditional Thatched and Wooden Roofs (Heritage or Rural Types)

In some rural or heritage buildings, thatched or fully wooden roofs are still used.

  • Typical faults: Rotten wood, loose thatch, insect infestation, or water penetration.

  • Our repairs:

    • Partial or full re‑thatching where needed.

    • Treating wood for rot and pests.

    • Installing or improving gutters and eaves to reduce water damage.
