Al Azyzya sits at roughly 589 metres above sea level, and its centre lies about 17 km from the centre of Riyadh. The neighbourhood is bounded by and close to the Southern Ring Road and the road to Al-Kharj, which means heavy traffic and dust are common. For roof waterproofing on residential buildings, this elevation and open exposure mean the roof takes strong sun in summer and sudden rain in short bursts, so membrane adhesion, drainage slopes and parapet junctions are checked first. These are where water usually finds its way in, and where a reflective protective coat is most useful for limiting heat on the membrane.
Before the visit, it helps to clear the roof of loose items and note any past leaks, including the rooms below where stains appeared and when. Bring the building's age and any earlier waterproofing records if you have them, and mention whether there is a bathroom or balcony above living areas, since those floors are waterproofed separately and need their own assessment. Ask the team how they will check the slope and drainage outlets, what surface preparation they will do before applying the membrane, and whether the reflective coat is included in the quote or is an add-on. Ask as well how the work will be scheduled around your household.
For a residential building, shared risers, tanks and pumps are checked as one system.
