Re Roofers: A Technical Guide to Roof Replacement & Why Hydroseal Is a
Roofing systems are one of the most essential structural components of any residential or commercial building. Over time, roofs deteriorate due to weather conditions, thermal expansion, UV radiation, mechanical stress, and water infiltration. When repairs are no longer effective, full roof replacement becomes necessary. This is where Re Roofers—companies or teams specialising in roof reconstruction and replacement—play a critical role.
In the UAE, high temperatures, dust exposure, occasional storms, and moisture variations place roofs under extreme pressure. A poorly installed or ageing roof can lead to significant structural damage, leakage, mold, and energy inefficiency. That’s why choosing experienced and technically capable Re Roofers—like the engineering-trained specialists at Hydroseal—is crucial.
This blog provides a complete technical overview of the roof replacement process, common roofing failures, system types, and why Hydroseal is a trusted partner for re-roofing projects.
Why Roof Replacement Becomes Necessary
A roof typically lasts 15–25 years depending on material quality, usage, and maintenance. However, several factors accelerate deterioration:
1. Water Leakage & Membrane Failure
Roof membranes crack or detach due to poor installation or ageing, allowing water to seep through.
2. Thermal Expansion
The Middle Eastern climate causes extreme day-night temperature differences, leading to roof movement and cracks.
3. UV Radiation
Intense sunlight degrades roofing materials over time.
4. Poor Drainage & Water Ponding
Flat roofs with inadequate slope accumulate water, increasing structural stress.
5. Corrosion
Steel roofing components can corrode due to humidity and moisture.
6. Structural Fatigue
Old buildings often have weakened substrates that require strengthening before re-roofing.
In such cases, repairs only offer temporary relief. Professional Re Roofers ensure that the roof is reconstructed, resurfaced, and waterproofed to modern engineering standards.
Key Indicators That You Need Re Roofers
Homeowners and facility managers should look for:
- Visible leaks or damp patches
- Sagging or uneven roof areas
- Cracked membranes or blistering
- Deteriorated sealants
- Rusted metal structures
- Mold growth on ceilings
- Poor insulation leading to heat gain
- Water ponding after rain
If any of these conditions are present, a roofing specialist should assess the system immediately.
Hydroseal’s Technical Approach as Professional Re Roofers
Hydroseal follows a structured engineering-based process for roof replacement.
Step 1: Detailed Roof Inspection
Hydroseal assesses:
- Membrane condition
- Existing waterproofing layers
- Thermal insulation
- Roof slope and drainage
- Structural strength of substrate
- Presence of cracks, rust, or weak zones
Advanced tools such as:
- Moisture meters
- Thermal imaging cameras
- Drone inspection (if required)
are used for precise diagnosis.
Step 2: Removal of Old Roofing System
All damaged materials are safely removed:
- Old membrane
- Failed sealants
- Weak insulation boards
- Rusted fasteners
- Debris from previous patch repairs
This ensures a clean base surface.
Step 3: Surface Preparation
This includes:
- Crack repairs
- Priming
- Smoothing irregular surfaces
- Reinforcing weak zones
- Applying anti-corrosion coatings
Proper preparation ensures maximum adhesion and durability for the new roof system.
Step 4: Installation of New Insulation
Depending on thermal requirements, Hydroseal installs:
- PIR (Polyisocyanurate) insulation
- XPS (Extruded Polystyrene)
- EPS boards
These materials significantly reduce heat transfer and improve indoor temperature control.
Step 5: Application of the New Waterproofing System
Hydroseal selects the waterproofing system based on building type, exposure, and performance requirements.
Common options include:
1. Bituminous Membrane Roofing
- Torch-applied or self-adhesive
- Highly resistant to water
- Durable under high temperatures
- Suitable for most UAE roofs
2. Polyurethane Liquid Roofing
- Seamless and fully bonded
- High flexibility
- Ideal for roofs with complex shapes and details
3. Acrylic Roofing Systems
- UV resistant
- Eco-friendly
- Suitable for mild waterproofing needs
4. TPO / PVC Roofing Membranes
- High reflectivity (energy efficient)
- Heat-welded joints
- Long service life
Hydroseal installs systems according to international manufacturer specifications.
Step 6: Testing & Quality Control
Hydroseal performs:
- Water ponding test
- Visual inspection
- Insulation integrity check
- Membrane adhesion test
Quality control ensures the roof meets performance requirements.
Step 7: Handover, Documentation & Warranty
After completion, Hydroseal provides:
- Warranty documentation
- Maintenance guidelines
- As-built drawings (if required)
A proper handover guarantees transparency and long-term trust.

Why Moisture Vapour Barriers are Critical for Concrete Floors
Concrete may look solid, but it’s surprisingly porous. Beneath the surface, tiny capillaries allow moisture vapour to move upward from the ground or the slab itself. This invisible process called moisture vapour transmission can create damage on the floor. For facility managers, contractors, and even commercial kitchen operators, understanding MVT and how it can be stopped is key to achieving lasting and high-performance flooring.The Hidden Problem of Your FloorEvery concrete slab contains moisture. Even when it appears dry, vapour pressure inside the slab can push moisture to the surface over time. When that happens under a coating, adhesive or floor system, results can be costly. Some of the costly solutions areDelamination: Rising vapour causes coatings to lose adhesion, peeling away from the surface.Bubbling or Blistering: Pressure pockets from under the coating, creating unsightly blisters and weak spots.Coating Failure: Continuous moisture exposure breaks down resins, causing cracks, discolouration or full system...
