What is specific about Rafha for roof waterproofing
The centre of Rafha sits about 451 m above sea level (SRTM open elevation data).
Will a rest house or farm roof in Rafha really need waterproofing, given how dry the air can be? Rafha sits at the northern edge of the Nafud desert, with its town centre about 451 m above sea level, and roofs here face intense sun, sharp temperature swings and occasional heavy rain that can pool on flat surfaces. For owners of rest houses and farms, the answer is yes: a sound roof membrane keeps stored water, equipment and living spaces protected through every season. The main options for a flat roof are liquid roof waterproofing at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², and spray foam at SAR 20–45 per m², with XPS boards in the range of SAR 12–30 per m² as an insulating layer. Your choice depends on the roof's condition, its size and how much heat you want kept out of the rooms below.
Before any material is recommended, the visit begins with a walk across the whole roof to look for cracks, blistering, ponding areas and old patches that have started to lift. Cracks are measured along their length, since crack injection is priced at SAR 40–120 per metre, and the technician notes where water has been tracking into walls or ceilings. The roof area is measured in square metres so the quote can be built from the per-m² rates. Where a farm has a water tank on the roof, its interior is checked as well, because tank internal coating is priced at SAR 25–60 per m². The inspection then ends with a short discussion of which system suits the building and how it will be prepared.
To make the visit efficient, clear the roof of loose items, planters, cables and stored equipment so the surface can be fully examined. Keep a note of any past leaks, including the rooms affected and the months they occurred, because this history helps narrow down the likely source. Gather any previous repair records or details of earlier coatings, and let the technician know whether the roof is used for sitting, storage or water collection. Make sure access to the roof is safe and that a ladder or stair route is available. With these steps done, the visit can focus on what the roof actually needs rather than on guesswork.
Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.
When do you need roof waterproofing?
The following signs are worth checking before they grow:
- Water pooling on the roof

- The old waterproofing is cracking
Where the problem usually comes from
- Wrong falls towards the drains — we check this before anything else.
- Damaged waterproofing around tank and AC bases.
- Cracks in the roof slab.
How we choose the tool in Rafha
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
The steps in order
- 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.
