Roof waterproofing in Ahad Rafida: the local context

The centre of Ahad Rafida sits about 2055 m above sea level (SRTM open elevation data).

Is roof waterproofing worth the cost for an apartment building in Ahad Rafida? For most owners the answer depends on what the roof is facing. The centre of Ahad Rafida sits about 2055 m above sea level (SRTM open elevation data), so the roof is exposed to its own local conditions, and a leak that starts small can spread into the apartments below. Liquid roof waterproofing is priced at SAR 8–25 per m², and bitumen membrane at SAR 15–35 per m², so owners can compare options against the size of the roof before committing to work.

The inspection starts with a walk over the whole roof surface, looking for ponding, cracked screed, lifted edges and blocked drains. Inspectors check the joints around parapets, pipes and roof hatches, since these are where water most often gets in. Where cracks are found in the structure, crack injection is quoted per metre at SAR 40–120 per m, and the inspector will mark each crack so the length can be measured. The surface is then checked for trapped moisture, and the findings are written up with a separate line for each area so the owner can see which repairs are needed and which can wait.

Before the visit, gather the building's records, including any earlier roof works, warranties and the date of the last repair, because these help explain what has already been tried. Clear the roof access route and remove loose items, planters and stored materials that would block the inspector's view of the surface. Note where leaks have appeared inside the apartments and at what time of year, and take photographs if possible. Confirm who will be present for the visit, so that questions about access, noise and timing can be settled on the day rather than later.

In apartment buildings, the floor below is often where a leak shows first.
