What bitumen roof waterproofing includes
- Checking the roof surface and identifying points that need extra preparation before the rolls go down
- Cleaning the surface and removing failing layers and dirt that would weaken the bond
- Laying bitumen rolls with enough overlap at every seam between one strip and the next
- Sealing the roll edges at the parapet on both the horizontal and vertical faces
- Treating the specific points around drain bases, pipes and AC unit stands
- Confirming the layer is continuous with no break from the centre to every edge
From your call to the sealed roof

Call or message us on WhatsApp and tell us what shows on your ceiling or roof surface. We will guide you to the next step.

Preparing the surface first
The job starts by cleaning the surface of dirt and failing layers, because a roll only bonds well to a clean, sound base.
- 3
Laying and overlapping the rolls
The rolls are laid in parallel strips and each strip overlaps the next at the edge, because the seam between two strips is the most vulnerable point in any bitumen covering.
- 4
Sealing the edges and penetrations
The membrane edges are sealed at the parapet and around every drain base, pipe and AC stand, because these specific points are where water most often enters.

The service in Ash Shi’bah
In a district like Ash Shi'bah, the flat roof usually carries tanks, a parapet or drains. Cracks, joints and corners are the gaps water exploits. Bitumen is laid so rolls overlap completely and every joint is covered with a second coat, leaving no untreated point. Before starting, the roof must be checked for damp, cracks and cleanliness, because any debris or damp will weaken the bitumen's bond and the strength of the new layer.
Ash Shi'bah is a district in Al-Ahsa governorate in the Eastern Province, close to Al Qurayn, Julayjilah and Ash Shuqayq.
The first inspection reveals whether damp is present, because it stops bitumen from bonding strongly.

Questions about Bitumen roof waterproofing in Ash Shi’bah
Bitumen rolls suit flat concrete roofs in most cases. A very sloped roof or one finished with tiles needs a different assessment. The surface should be sound and free of deep cracking before the rolls go down; otherwise it needs extra preparation first.
The middle of the roof is usually flat and continuous. At the parapet, the horizontal membrane meets the vertical wall, forming a joint that moves with heat expansion and contraction. If that edge is not sealed well, water usually finds its way in there.
Clean, sound concrete usually needs a primer coat to open its pores and improve how the roll bonds to it. Laying a roll on an unprepared surface weakens the bond and leaves the layer prone to separating over time, especially with the temperature range.
The seam between two strips breaks the continuity of the waterproof layer. If the strips do not overlap enough and the edge is not pressed down until it bonds, a fine gap remains. That gap opens in summer heat and closes again, and water finds its way through it in every rainfall.
Bitumen suits a flat concrete roof that lets water in and needs a flexible protective layer that handles thermal expansion. If the problem is mainly heat with no visible water entry, another material may be more suitable. An initial assessment of the roof is what determines the right choice.
We inspect the roof for cracks, damp, cleanliness and joints. If damp or loose material is present, it must be dealt with first. A clean, dry surface is the only foundation for new bitumen.
Say if you see leaking or damp stains on the ceiling. Also tell us if there are tanks, drains or a parapet on the roof. A clear photo of the roof on WhatsApp helps us understand the situation faster.
