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).
Is a bitumen membrane on my roof in Alula going to crack open the first time the desert heat hits it? That is the question most property owners here ask, and the answer depends on the surface being sound before anything is laid. The centre of Alula sits about 697 m above sea level, so sites here see a mix of strong sun during the day and sharp temperature drops at night, and that daily movement is exactly what tests an old roof. A bitumen membrane is priced at SAR 15–35 per m², which sits in the mid-range of the waterproofing options listed for this area, so the cost is not the main thing to weigh. What matters is whether the membrane can bond to a surface that is clean, dry and stable.
The inspection starts with a walk over the whole roof to find where water has been getting in. Cracks, blisters and lifted old membrane edges are marked, and any crack that runs through the surface is noted for injection work, which is priced separately at SAR 40–120 per metre. Where the existing covering is failing across large areas, the crew checks whether the old layer can be left in place or needs to come off first. The aim is to confirm the base is firm enough to take new material, and to decide which repairs must come before the membrane goes down. Drainage points, outlets and upstands around the edges are also checked, because water pooling at these spots is a common cause of early failure.
Before the visit, clear the roof of loose items, planters and stored materials so the team can reach every section. Note any past leaks, including the rooms below where stains or damp have appeared, and keep records of previous roofing work if you have them. Make sure someone with authority over the building can be reached during the visit to approve the scope. If there is access to the roof through a hatch or stair, confirm it is safe and unlocked. With these steps done, the inspection can focus on the real condition of the roof rather than on delays, and you leave with a clear picture of what the bitumen membrane will need to hold up in the Alula climate.
The aim is to locate the cause with instruments first, so any opening is limited to one point.
