Will rain and summer heat damage the roof of a school in Afif, and what does it cost to stop it? Afif sits at a high altitude, with the centre about 1040 m above sea level (SRTM open elevation data), and roofs there face the full range of weather that a school building has to withstand. For a flat school roof, the most common solution is liquid roof waterproofing, which is priced at SAR 8–25 per m². Bitumen membrane is another option at SAR 15–35 per m², and XPS boards, which add insulation as well as protection, fall in the SAR 12–30 per m² range. The right choice depends on the roof's condition, its size and how the building is used.
Before any work is quoted, the inspection should follow a clear order. The surveyor first walks the full roof area and notes ponding water, blistered surfaces, and any cracks or open joints around parapets, drains and rooftop fixtures. Cracks are measured in metres, since crack injection is priced per metre at SAR 40–120 per m, so a clear count helps the quote stay accurate. The surveyor then checks the area in square metres, because liquid coatings, membranes and boards are all priced per m². Finally, the surveyor looks at adjoining elements, such as a rooftop water tank, which may need tank internal coating at SAR 25–60 per m² if it is part of the same scope.
To make the visit productive, the school should prepare a few things in advance. Gather any previous roof repair records, warranty papers and drawings that show the roof layout and drainage points. Clear access routes to the roof and the plant room, and arrange for a staff member to escort the surveyor. Note any leaks inside the building, with dates and locations, since staining on ceilings often shows where water is entering. Share the school's timetable so that noisy or messy work can be planned around teaching hours. With this information ready, the inspection can move straight to a practical, costed plan for the roof.
For schools, the larger jobs are planned for weekends and holidays.
Signs that call for roof waterproofing
The following signs are worth checking before they grow:
- Stains on the top-floor ceiling after rain
- Water pooling on the roof
- The old waterproofing is cracking
The most common causes
- Damaged waterproofing around tank and AC bases — we check this before anything else.
- Wrong falls towards the drains — we check this before anything else.
- Cracks in the roof slab — we check this before anything else.
How we choose the tool in Afif
| Tool | What it finds | When we use it in Afif |
|---|---|---|
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
How the work is done, step by step
- Survey: Falls, drains and the condition of the old layer are recorded.
- Preparation: Cleaning and repairs before any new layer.
- Primer: The base coat that the system needs.
- Waterproofing layers and details: Corners, upstands and bases get their own detail.
- Flood test: The roof is flooded and checked before it is covered.
