Roof thermal insulation in Aldarb: for companies (annual contract)
In short: In Aldarb (Aldarb), roof thermal insulation (for companies (annual contract)) begins with the roof, falls and drains survey and the thermal camera; nothing is opened until the position is clear. Aldarb is about 18.7 km from the sea coast (OpenStreetMap). Published price: Spray foam (per m²), SAR 20–45 per m²; anything else is quoted after the inspection.
Why roof thermal insulation differs in Aldarb
Aldarb is about 18.7 km from the sea coast (OpenStreetMap). The centre of Aldarb sits about 79 m above sea level (SRTM open elevation data).
Does a company's roof in Aldarb really need thermal insulation, and how would we know? The centre of Aldarb sits about 79 m above sea level, and the town is about 18.7 km from the sea coast, so roofs here face a dry, inland climate with strong daytime heat that builds up under the roof slab. For a business with a flat roof, that heat passes straight into offices, stores and production space, raising cooling costs throughout the year. Our annual contract for companies is designed to check the roof's condition and insulation needs on a regular schedule, so problems are caught before they spread into the building below.
The inspection follows a set sequence. A technician first walks the full roof area to look for cracks, ponding water, blistered surfaces and failed joints around drains, parapets and roof-mounted equipment. Where cracks are found, the length is measured, because crack injection is quoted per metre (SAR 40–120 per m). The roof surface is then checked for the type of covering already in place, whether that is liquid roof waterproofing (SAR 8–25 per m²), a bitumen membrane (SAR 15–35 per m²) or a spray foam layer (SAR 20–45 per m²). Finally, the technician records the areas that would benefit from added thermal insulation, such as XPS boards (SAR 12–30 per m²), and gives the site a written summary of what was found and the options open to the company.
To make the visit efficient, please prepare a few items before the technician arrives. Gather any previous roofing or insulation records, including dates of past repairs and the materials used. Make sure the roof access route is clear, and that the stairs or ladder and roof hatch can be used safely. Note any areas inside the building that feel unusually hot or show damp patches on the ceiling, as these help the technician trace the problem. If there are water tanks, plant rooms or basement areas that connect to the roof drainage, list them too, since tank internal coating (SAR 25–60 per m²) and basement works may be relevant to the overall plan.
For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
Signs that call for roof thermal insulation
The following signs are worth checking before they grow:
- The AC runs for long hours in summer
- Strong heat on the top floor
- The ceiling stays hot at night
The most common causes
- No thermal insulation under the roof protection — we check this before anything else.
- A common cause: old insulation that has deteriorated.
How we choose the tool in Aldarb
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Thickness measurement at spread-out points | Whether the thickness in the quote was achieved | Limits: for foam and liquid-applied layers |
| Thermal camera | Wet areas and heat loss in the roof | Limits: needs a day–night temperature difference |
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
From the first visit to the report
- Thermal survey: Hot areas of the roof are mapped.
- Choosing the system: The material and thickness are agreed in the quote.
- Installation: The layer is installed and protected.
- Measurement and documentation: Thickness is measured at spread-out points.

Common questions about roof thermal insulation in Aldarb
What is the first step of roof thermal insulation (for companies (annual contract))?
We start with thermal survey (hot areas of the roof are mapped), then choosing the system (the material and thickness are agreed in the quote).
How much does roof thermal insulation cost in Aldarb?
From our published price list: Spray foam (per m²) SAR 20–45 per m²; XPS boards (per m²) SAR 12–30 per m². Quantities are confirmed at the inspection.
What do I get at the end?
The documented thickness, materials and batch numbers, in a technical report that carries a verification code.
Common mistakes we see
- Relying on reflective paint alone on an uninsulated roof
What you receive
The written output: the documented thickness, materials and batch numbers. The report is numbered and can be checked with its verification code.
If you live in Aldarb and are new to the area
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
- If you rent, tell your landlord or building management before the visit and agree in writing who pays; the written report can be shared with them.
- Have access ready to the water meter, the tank hatches, the roof and the main valve; in apartment buildings the roof keys are often with the building guard (haris).
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
