What is specific about Alahsa for roof waterproofing
Team note on Alahsa: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. The centre of Alahsa sits about 152 m above sea level (SRTM open elevation data).
Is a rest house or farm roof in Alahsa worth waterproofing before the summer rains arrive? Most owners ask this because the roof is the one part of a property that works hardest in the sun and the occasional downpour. Alahsa's centre sits about 152 m above sea level, and that low, flat setting means water that cannot run off quickly tends to pool and seep. Liquid roof waterproofing is priced at SAR 10–25 per m², bitumen membrane at SAR 15–35 per m², and XPS boards at SAR 10–30 per m², so there are several options to match the roof and the budget.
Our inspection starts with a walk over the whole roof surface to look for cracks, blistered coatings, ponding areas, and joints around parapets and drains. Where cracks are found, crack injection is quoted at SAR 40–120 per metre, and the team notes every linear metre so the quote matches the actual damage. Next, the surface is checked for loose material and moisture, since coatings do not bond well to a wet or dusty base. The inspector then recommends a system that suits the roof type, whether a liquid layer, a membrane, or insulating boards, and explains why. Epoxy coating at SAR 35–90 per m² or spray foam at SAR 20–45 per m² may also be suggested for specific areas such as walkways or sections exposed to heavy wear.
Before the visit, clear the roof of furniture, potted plants, and loose items so the inspector can reach every section. Note any past leaks, the rooms they affected, and the dates you noticed them, because this history helps pinpoint problems. Make sure the access ladder or roof hatch is safe and unlocked, and let us know if there are water tanks, since tank internal coating is priced at SAR 25–60 per m² and can be assessed in the same trip. Having this information ready keeps the visit short and the estimate accurate for your rest house or farm.
Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|

| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |

Questions from Alahsa
Is it possible to unclog drains without breaking the floors?
In most cases, yes: camera inspection and high-pressure water jetting clear the blockage from drain openings and inspection chambers without breaking anything, except when there is an actual break in the pipes.
Does renovation include treating dampness and insulation?
Usually yes, since dampness treatment is an essential part of renovation, especially in Al-Ahsa. The contractor identifies the source of the leak and then carries out the appropriate insulation. Mention the dampness problem in your request description.
What is the difference between foam insulation and roll insulation?
Foam is sprayed on as a continuous layer with no seams and provides both thermal and water insulation, while rolls are separate pieces that require joining and mainly focus on water insulation.
