The centre of Alkharj sits about 439 m above sea level, a fact drawn from SRTM open elevation data. For roof and drain work this matters because rainwater on a flat roof has to find its way to an outlet, and a site at this height on the central Najd plateau is shaped by open terrain and seasonal storms rather than steep valleys. Owners should expect that drainage outlets, parapet gutters and roof falls will be tested by short, heavy rainfalls that arrive faster than the existing pipework can clear. Checking that outlets are unblocked and that falls still direct water toward them is therefore the first practical step before any winter or spring storm.
The local character also affects the price and scope of a visit. A standard maintenance visit in Alkharj is typically SAR 150–400 per visit, depending on access, the number of roof levels and how many drains need clearing. Where the surface has already deteriorated, restoration is priced per square metre at SAR 50–150 per m², which reflects the amount of membrane, screed or coating that has to be replaced. Because the work is measured this way, a clear survey of the roof area and the drain positions lets the technician give an accurate scope before work begins, and it helps owners compare a routine clean against a full restoration on equal terms.
Owners who keep roofs and drains in good order in Alkharj tend to avoid the same few errors. They do not wait for ponding to appear before calling for a visit, and they do not allow debris, sand and leaf litter to collect around outlets, since this is what blocks water during a storm. They also avoid patching small cracks in a membrane without checking the falls and the outlet height, because a repair that ignores drainage simply moves the leak. Finally, they do not treat a single maintenance visit as a substitute for inspecting the roof after heavy rain. Regular checks, timed before the wet season, are the simplest way to protect both the structure and the interior below.
Each job ends with a written report that carries a verification code you can check on our site.

Short answers for Alkharj
Does an underground tank require waterproofing even if it is new?
Yes, concrete is naturally porous, which can lead to leaks or groundwater seepage. Applying epoxy or cementitious insulation from the start maintains water quality and protects the structure from corrosion.
Do you need to evacuate the building during renovation work?
It depends on the type and scope of the work. Surface work such as plastering and painting usually does not require evacuation, while partial or full evacuation may be advised in cases of structural reinforcement, and the contractor determines this after inspection.
