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 Al Olaya District
Homes in a district like Al Olaya have flat concrete roofs exposed to intense summer heat and rare but sometimes heavy rain. Salts and damp from the wet ground in Al-Ahsa affect lower walls, and water entering through the roof makes it worse. The roof usually has a parapet, tanks, drains and pipes, sensitive areas needing strong sealing. Work begins by cleaning and preparing the roof and filling cracks, then bitumen rolls are heated and laid firm, with great care at the parapet, drains and pipes. The roof is checked first.
Al Olaya District is a district in Al-Ahsa governorate in the Eastern Province, close to Al Uwaimiriyah District, Al Thulaythiyah District and Ar Rawdah District.
The joints between rolls and areas around the parapet and drains are where water breaks through fastest if not sealed carefully.

Questions about Bitumen roof waterproofing in Al Olaya District
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.
It may come from the roof at cracks and joints, or from outer walls. Bitumen stops water entering from the roof, but the problem must be checked first to find the real source.
Say when the damp started and where in the house, describe the roof condition and whether it has tanks or pipes or visible cracking, and send clear photos of the roof and damaged walls on WhatsApp.
