Roof waterproofing in Alaridah: the local context
The centre of Alaridah sits about 2591 m above sea level (SRTM open elevation data).
Will waterproofing my roof mean tearing up the whole structure? In Alaridah, the answer depends on the system chosen and how the work is planned, and many roof jobs can be done without breaking into the living space below. The centre of Alaridah sits about 2591 m above sea level (SRTM open elevation data), a height that matters when planning exposed roof work. Liquid roof waterproofing is priced at SAR 8–25 per m², while bitumen membrane runs SAR 15–35 per m², and XPS boards cost SAR 12–30 per m². Each option sits on or above the existing surface, so the choice is usually about budget and exposure rather than demolition.
The inspection starts with a walk over the roof to find where water is actually getting in, since ponding, cracked surfaces and failed joints each call for a different fix. Crack injection is priced at SAR 40–120 per metre, so a surveyor will often measure the length of visible cracks to estimate that line item separately from the surface coating. The team then checks the parapets, drains and edges, noting any area where an existing membrane has lifted or blistered. They record the square metres of roof to be covered so the coating quote matches the real area, and they note whether any adjoining walls or water tanks also need attention. The result is a written scope that shows exactly which surfaces will be treated and at what rate.
Before the visit, clear access to the roof and remove any loose items, plant pots or stored materials from the surface so the inspector can see the bare substrate. Make sure the route to the roof is safe and that someone can open the hatch or door on the day. If there are leaks inside, note the rooms affected and when the water appears, since rain timing helps the team pinpoint the source. Keep any previous waterproofing records or invoices, as they show what was applied before. Having these details ready lets the inspection move quickly and keeps the final quote focused on the roof itself, with the work done from above rather than through the rooms below.
The aim is to locate the cause with instruments first, so any opening is limited to one point.
Signs worth paying attention to
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.
- A common cause: damaged waterproofing around tank and AC bases.
- A common cause: cracks in the roof slab.
Tools we use in Alaridah
| 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 |
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.
