What is specific about Alaridah for roof waterproofing
The centre of Alaridah sits about 2591 m above sea level (SRTM open elevation data).
Roof leaks are the most common problem we see on restaurant roofs in Alaridah. Kitchen extraction ducts, rooftop units and heavy foot traffic from staff all wear down the surface over time, and water often shows up first in the dining area ceiling or near the cold store. Because restaurant roofs are rarely left alone for long, a small failure can go unnoticed until stock or equipment is affected.
The local conditions in Alaridah change how we approach the job. The centre of Alaridah sits about 2591 m above sea level (SRTM open elevation data), so the roof is exposed to a different climate from lower-lying parts of the Kingdom, and that affects how the surface expands, cools and ages. For that reason we look closely at the roof's condition before choosing a system. Liquid roof waterproofing, which is priced at SAR 8–25 per m², suits many flat restaurant roofs with awkward penetrations, while a bitumen membrane, at SAR 15–35 per m², may suit areas that need a heavier, more continuous layer. Where insulation is also needed, XPS boards at SAR 12–30 per m² can be added. Cracks in the parapet or the slab are treated separately with crack injection at SAR 40–120 per metre, so the repair matches the defect instead of covering everything with the same product.
Before the visit, ask the provider to explain which system they recommend and why it suits your roof. Ask them to quote per square metre and per metre for each item, so you can compare the scope clearly. Ask how they will protect kitchen areas and rooftop equipment during the work, and whether they will inspect the drainage outlets as well as the surface. Finally, ask what the repair covers and how they will check the result before you accept the job. A clear answer to these questions tells you how carefully the work will be done.
For restaurants, visits are planned outside service hours and recorded for the premises file.

Tools and methods, and when we use them
| Tool | What it finds | When we use it in Alaridah |
|---|---|---|
| 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.
