Roof waterproofing in Aldiriyah: for companies (annual contract)
In short: Roof waterproofing (for companies (annual contract)) in Aldiriyah starts with the roof, falls and drains survey, then the moisture meter for ceilings and walls, before anything is opened. The centre of Aldiriyah sits about 655 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.

Roof waterproofing work in Aldiriyah starts with the elevation of the site. The centre of Aldiriyah sits about 655 m above sea level (SRTM open elevation data), so our technicians first look at how water is likely to move across a roof and how the roof drains in this location. Because the roof surface and its falls decide where water collects, the first check is the slope and the outlets, followed by the condition of the existing finish. For companies on an annual contract, this first pass is recorded so that each later visit can be compared with the same baseline.
Several decisions cannot be made from a desk. The choice between liquid roof waterproofing, bitumen membrane, spray foam or XPS boards depends on the substrate, the amount of foot traffic, the size of the roof and how the building is used, and these are assessed on the site visit. Our technician will also judge the depth and extent of any cracks, the state of parapets and upstands, and whether the work can be carried out without disrupting staff. Where the roof connects to a basement or a water tank, the scope may be extended, and any change to the plan is agreed with the company before work starts. Quantities and final costs are confirmed only after this inspection, because the price ranges for each system vary widely with the conditions found.
To help the technician prepare, companies are asked to share the building drawings, the roof area, any previous waterproofing records and the dates of past leaks. It is useful to note which rooms sit below the roof, whether any equipment or tanks are fixed to it, and when the roof is normally accessed. Photographs taken after rainfall are especially valuable, as they show where water actually pools. With this information and the site survey, the technician can propose a system suited to the roof and to the operating needs of the company, and the annual contract can then schedule inspections and maintenance around that plan.
For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
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
Causes we see in the field
- Damaged waterproofing around tank and AC bases.
- 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 Aldiriyah
| 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 |
| 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 |
From the first visit to the report
- 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.
