Does a rest house or farm in Ahad Rafida really need its roof waterproofed, and what will it cost? The short answer is yes if water is getting through, and the cost depends on the system chosen. Ahad Rafida's centre sits about 2055 m above sea level (SRTM open elevation data), so properties here are set high in the hills, where exposed roofs take the full force of weather. For roofs, liquid roof waterproofing typically falls within SAR 8–25 per m², bitumen membrane within SAR 15–35 per m², and XPS boards within SAR 12–30 per m². Choosing between them depends on the roof's condition and how it is used, which is why the next step matters.

A site visit starts with a walk across the roof to look for cracks, lifted edges, ponding areas and old patches that have failed. Crack injection, which runs SAR 40–120 per metre, is often considered where cracks are isolated rather than widespread. Where the surface has worn over a large area, the inspector checks whether a new membrane or liquid layer will bond properly. The inspection also looks at drainage outlets, parapets and the junctions where the roof meets walls, because leaks often start at these points rather than in the open field. Where water has reached the interior, the inspector will look at ceilings and walls below, and may check bathrooms and any rooms next to the roof, where spray foam (SAR 20–45 per m²) or epoxy coating (SAR 35–90 per m²) may be considered for particular surfaces.

Before the visit, gather any earlier repair records, notes on when leaks appear and whether they follow rain or wind, and photographs taken after storms if you have them. Clear the roof of loose items, furniture and stored materials so the surface can be examined fully, and make sure access hatches or ladders are safe to use. Note which parts of the property are in use, such as a farm storage area or a rest-house room, so the recommendation fits how the building is actually used. Having this information ready helps the inspection cover the right ground and makes the resulting quote easier to compare.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

When do you need roof waterproofing?

These are the signs most often linked to roof waterproofing:

• The old waterproofing is cracking

• Cracks in the roof slab — we check this before anything else.
• Damaged waterproofing around tank and AC bases — we check this before anything else.
• A common cause: wrong falls towards the drains.
