Overview

What you should know about roof insulation

Most top-floor problems in Riyadh start at the roof: leaks after the first rain, damp ceilings, or heat the AC cannot keep up with. The cause is rarely the absence of insulation, it is usually insulation applied without proper surface preparation, slopes, joints and drain detailing.

So we start with diagnosis, not material: roof type (concrete or metal), the condition of old layers, slopes and ponding, and the goal, stopping leaks, cutting heat, or both. Then we recommend one clear system and explain why.

Where it fits

Villa and building roofs

Protect the top floor from leaks and heat, under tiles or as an exposed finish.

Metal roofs and hangars

Foam or polyurea covers corrugations, fasteners and joints without seams.

Old, failed roofs

Remove detached layers and rehabilitate the roof instead of patching.

New buildings

Correct insulation from day one saves future repairs and tile removal.

Method

  1. 1

    Inspection & diagnosis

    Surface preparation

    Full cleaning, removal of failed layers, crack repair and slope correction with foam concrete.

  3. 3

    Detailing

    Reinforce corners, pipes, drains and AC plinths, the most common leak points.

  4. 4

    System application

    Waterproofing and/or thermal layers at the correct thickness and sequence.

  5. 5

    Protection layer

    Reflective acrylic, geotextile or tiles depending on roof use.

Pricing

What determines the price?

We price after inspection because these factors vary by site, our quotation lists each item explicitly.

  • Roof area and type (concrete or metal).
  • Condition of old insulation and whether removal is needed.
  • Slope correction or foam concrete screed.
  • The selected system, thickness and number of layers.
  • The final protection layer.

We inspect your site and send a quotation stating the system, thickness, preparation and warranty line by line.

FAQ

Frequently asked questions

Does roof insulation stop leaks permanently?

The right system on a properly prepared roof stops leaks for its full service life. Most failures come from ignoring slopes, joints and drains, which is why we treat them first.

Waterproofing or thermal insulation?

Waterproofing stops water; thermal insulation reduces heat transfer. In Riyadh we usually recommend both, spray foam delivers both in one layer.

How long does a villa roof take?

Typically one to three days depending on area, system and curing time.

How much does roof insulation cost?

Pricing is per square metre and depends on the system and roof condition. We provide a written quotation after a free inspection.
