Roof waterproofing in Ahad Rafida starts with the altitude. The centre of Ahad Rafida sits about 2055 m above sea level (SRTM open elevation data), which means a roof here is exposed to a different climate pattern than lowland sites on the Red Sea coast or the eastern plains. A technician should first confirm how the existing roof surface is sloped, where water pools, and whether earlier coatings have lifted or cracked. These are the checks that come before any material is discussed, because the right system depends on the roof as it actually stands.
Several things are left to the site visit and cannot be settled from a distance. The technician needs to see the roof surface in person, measure the true area, check the parapets, drains and outlets, and judge whether the deck is sound enough to take a new layer. Cost is also a matter for the visit. Liquid roof waterproofing typically falls between SAR 8 and SAR 25 per m², bitumen membrane between SAR 15 and SAR 35 per m², and XPS boards between SAR 12 and SAR 30 per m², but the final figure depends on what the inspection reveals. Crack injection is priced per metre, at SAR 40 to SAR 120 per m, so the number of cracks found on site will shape the quote directly.
Information that helps the technician is worth gathering before the visit. Note when the leak first appeared, whether it follows rain or occurs in dry weather, and which rooms lie directly below the affected area. Photographs of the roof and any staining inside are useful. If a water tank sits on the roof, mention it, since tank internal coating is separately priced at SAR 25 to SAR 60 per m². Access arrangements, parking for the crew, and the times when the building is quiet also help the work proceed smoothly. A clear record of these details lets the technician arrive prepared and keeps the job focused on the problem.
Each job ends with a written report that carries a verification code you can check on our site.
Signs worth paying attention to

- The old waterproofing is cracking
- Water pooling on the roof
- Stains on the top-floor ceiling after rain
The most common causes
- A common cause: cracks in the roof slab.

| 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 |
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
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.
