Roof waterproofing in Alhait: preventive periodic check
In short: In Alhait (Alhait), roof waterproofing (preventive periodic check) begins with the roof, falls and drains survey and the moisture meter for ceilings and walls; nothing is opened until the position is clear. 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.
Before we start: what we know about Alhait
The centre of Alhait sits about 980 m above sea level (SRTM open elevation data).
The owner of a typical low-rise house in Alhait, with a flat concrete roof that takes the afternoon sun and an occasional winter downpour, often notices nothing until a damp patch appears on a ceiling. By then water has usually been finding its way in for some time. A preventive periodic check is a simple way to catch problems while they are still small and cheap to fix, rather than after they have spread into the walls and insulation below.
The centre of Alhait sits about 980 m above sea level, so the town sees strong daytime heating followed by cooler nights. That daily swing makes the roof surface expand and contract, which opens hairline cracks and lifts the edges of old coatings. Owners should treat the roof as a surface that works hard every day. Liquid roof waterproofing is typically priced at SAR 8–25 per m², and bitumen membrane at SAR 15–35 per m², so a regular inspection that catches a failing seam early is far more economical than repairing a leaking slab. Crack injection, at SAR 40–120 per metre, is also best kept for small openings rather than wide, neglected ones.
Begin by walking the roof once a season, ideally after the hottest months and again before the rains. Look for blistering, peeling, ponding water that stays after rain, and any crack along the parapet or around drains and pipe penetrations. Clear debris from the drains so water can leave the surface quickly. Next, note the area of each damaged section, since this sets the scale of any repair. Mark cracks and measure their length, because crack injection is quoted per metre. Check the rooms directly below for stains, soft plaster or flaking paint, and record where they appear. Finally, arrange a qualified assessment before the next rainy period, comparing the cost of a targeted patch against a full re-coat. Keep a dated record of each check so that changes from one season to the next are easy to spot.
Preventive checks follow a written schedule instead of waiting for a fault.

How we choose the tool in Alhait
| Tool | What it finds | When we use it in Alhait |
|---|---|---|
| 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 |
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
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.
