Roof waterproofing in Alhait: with a verifiable technical report
In short: Roof waterproofing (with a verifiable technical report) in Alhait starts with the roof, falls and drains survey, then the moisture meter for ceilings and walls, before anything is opened. The centre of Alhait sits about 980 m above sea level (SRTM open elevation data). Pricing starts from Liquid roof waterproofing (per m²) (SAR 8–25 per m²), and other items are quoted after the visit.
What is specific about Alhait for roof waterproofing
The centre of Alhait sits about 980 m above sea level (SRTM open elevation data).
Roof waterproofing work in Alhait starts with the height of the site. The centre of Alhait sits about 980 m above sea level (SRTM open elevation data), so a roof here faces a different climate from coastal cities, and that shapes what the technician checks first. Before any material is chosen, the roof surface, its falls toward outlets, and the condition of any existing layer are inspected. Liquid roof waterproofing, which typically costs SAR 8–25 per m², and bitumen membrane, at SAR 15–35 per m², are compared against the existing finish so the new layer bonds properly rather than lifting at the edges.
Some things can only be settled on the site visit. The technician needs to see the actual roof area, the number of penetrations such as pipes and vents, and the state of the parapet and drainage. Cracks are assessed in person; if a crack needs injection, the work is priced per metre at SAR 40–120 per m, and that length can only be measured by walking the roof. Whether a tank sits on the roof also matters, since tank internal coating (SAR 25–60 per m²) is a separate scope and is confirmed only once the tank is inspected. The visit is also where the homeowner can point out any past leaks, so the report reflects real history rather than assumptions.
Information that helps the technician prepare is simple and practical. Tell us the roof's approximate size, when it was last treated, and whether water has ever come through a ceiling, and note whether the roof is accessible for ladders and materials. Mention any plans to add an extra floor or equipment, because these change the load and the layer chosen. Photographs of the roof and of any stains inside the building are useful. With this information, the technician can prepare a written report that sets out the method, the materials, and the reasoning, so you can review the work before it begins.

Signs that call for roof waterproofing
The following signs are worth checking before they grow:
- Water pooling on the roof
- Stains on the top-floor ceiling after rain
- The old waterproofing is cracking
Where the problem usually comes from
- Wrong falls towards the drains — we check this before anything else.
- A common cause: damaged waterproofing around tank and AC bases.
- Cracks in the roof slab — we check this before anything else.
Tools and methods, and when we use them
| 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 |
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.
