Before we start: what we know about Alula
Main roads in or near Alula: King Abdullah Road. The centre of Alula sits about 697 m above sea level (SRTM open elevation data).
The centre of Alula sits about 697 m above sea level, according to SRTM open elevation data. That height means the town sees a dry, sun-heavy climate with wide temperature swings between day and night, and its roofs take a steady beating from heat and dust. For companies with flat roofs, this is the starting point for every plan we draw up. Surfaces are checked for thermal expansion, and the membrane chosen must stay flexible through hot afternoons and cooler nights.
Liquid roof waterproofing is priced at SAR 8–25 per m², and bitumen membrane at SAR 15–35 per m². Under the annual contract, we match the system to the roof rather than the other way round. A seamless liquid layer suits roofs with many corners and rooftop units, because it leaves no joints to lift in the sun. A bitumen membrane suits larger open decks where a continuous sheet can be laid quickly. XPS boards, at SAR 12–30 per m², can be added where insulation is needed alongside waterproofing, which keeps rooms below cooler during long summer days.
Owners who run annual contracts tend to avoid a few predictable errors. The first is waiting for a visible leak before booking an inspection, since small cracks often open long before water reaches a ceiling. Crack injection, priced at SAR 40–120 per metre, is far cheaper when done early. The second is painting over a damp or dusty surface, which stops new layers from bonding and causes early peeling. The third is treating the roof as a one-time job rather than a yearly check. A scheduled review each year lets our crews spot wear, clear drains and renew coatings before problems spread.
For companies, an annual contract sets the scope, the visit schedule and the reports in writing.

| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| 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 |
