Wellcool provides terrace heatproofing services in Pakistan for open terraces, rooftop sitting areas and upper-floor decks that sit above living rooms and bedrooms. We use walkable, durable systems that cut heat into the rooms below while standing up to daily foot traffic, furniture and monsoon rain.

Less heat through the deck
Heat and water sealed together
In many Pakistani homes the terrace is far more than a roof. It is where families sit on summer evenings, dry clothes, keep plants, host guests and sometimes sleep on the hottest nights. Upper-floor terraces in modern houses and apartments often sit directly above bedrooms or lounges, so heat soaking through the terrace slab goes straight into living space. At the same time, terraces get far more foot traffic than an ordinary roof, and they often have tiles, planters, railings and furniture that complicate any treatment. Terrace heatproofing therefore needs a different approach from a simple roof coating: the system must reduce heat, stay waterproof and survive daily use.
Wellcool designs terrace heatproofing around how you actually use the space. For uncovered decks we offer tough, walkable reflective coatings; for tiled terraces we can install insulation and waterproofing beneath new light-coloured tiles; and for partially covered areas we treat both the open slab and the junctions with walls and doors. Each job starts with an inspection of slopes, drains, tile condition and the rooms beneath, so the finished terrace is cooler, drier and still comfortable to use.
A terrace faces the same sun as a roof but carries extra demands. People walk on it every day, chairs and tables are dragged across it, planters sit on it holding damp soil, and water from washing, plants and rain must drain away quickly. Ordinary roof coatings can wear through quickly in heavily used paths, and heavy mud layers are impractical where people need a clean, even surface. Terraces also usually have doors opening onto them from indoor rooms, and the junction between the terrace floor and the door threshold is one of the most common leakage points in Pakistani homes.
Effective terrace heatproofing balances heat reduction, waterproofing and durability. The system must keep heat out of the rooms below, stop water from seeping into the slab, and provide a surface that stays safe, non-slippery and good-looking under daily use.
Your terrace likely needs treatment if you notice:
Finishes chosen to handle walking and furniture.
Careful sealing at doors, walls and railings.
Protection under pots and planter boxes.
Clean, even finish suitable for living spaces.
For open concrete terraces, we apply a primer and a tougher, traffic-grade reflective coating system, sometimes with an anti-slip texture in walking areas. It reflects sunlight, resists water and handles normal foot traffic. It is lighter and quicker than retiling and is ideal for terraces used for sitting and drying clothes.
Where the terrace will be retiled, we waterproof the slab, lay insulation boards, add a protective screed to slope, and then fix light-coloured tiles. This gives the best thermal performance and a classic tiled finish, and is suitable for family terraces above bedrooms.
If existing tiles are sound and well bonded, specialised primers and coatings can be applied over them after cleaning and grout repair. This avoids demolition while improving heat reflection and sealing grout lines against water.
Light-coloured, high-reflectance tiles or pavers laid over a waterproofed base keep the walking surface cooler than dark tiles or bare concrete. Combined with an insulated bed, they provide a comfortable, attractive terrace.

The edges of a terrace are where most problems begin. Door thresholds are often set too low, so water from rain or washing runs toward the door and seeps under the frame into the room. Wall junctions crack as the terrace slab expands in the heat. Railing posts drilled into the slab create holes that let water in. During terrace heatproofing we pay special attention to these details: forming upstands along walls, sealing threshold joints with flexible sealant, adjusting slopes away from doors where possible and sealing around every railing base. These small details make the difference between a terrace that stays dry and one that causes damp ceilings within a year.
Many families love keeping plants on their terraces, but planters can damage both heatproofing and waterproofing if not managed correctly. Pots placed directly on the floor trap moisture, roots can find small cracks, and frequent watering keeps patches of slab permanently damp. We recommend raising pots on stands, using trays, and keeping planters away from drains. For built-in planter boxes, we waterproof the inside of the box separately with root-resistant detailing. Plants can then provide shade and cooling without putting the terrace at risk.
Terraces need slightly more careful drainage than plain roofs because they are washed frequently and have obstacles like furniture and planters. Water left standing on a terrace not only causes leakage but also leaves dirt marks that reduce reflectivity. Where slopes are poor, we correct them with screed before the finish layer. Drain outlets are cleaned, enlarged where necessary and fitted with grates to keep leaves out.
Costs depend on the condition and use of your terrace, so we quote only after inspection. Main factors are:

A heatproofed terrace is not only better for the rooms beneath; it is also more pleasant to use. A reflective or light-tiled surface stays much cooler underfoot in the evening, so families can sit outside sooner after sunset. Adding shade sails, pergolas or creepers can further improve comfort. Because the surface releases less stored heat, the air on the terrace also cools faster at night, making it suitable for evening gatherings during the hottest months.
In apartment buildings, upper units often have private terraces above neighbours’ living spaces, and in commercial plazas terraces may be used as rooftop seating or restaurants. In these cases, heat and water problems affect other people too, so reliable treatment is even more important. We can work with building management, schedule work to minimise disruption and use finishes appropriate for public or semi-public use. Larger commercial terraces are also covered under commercial building heatproofing.
Use furniture with rubber feet or pads, lift rather than drag heavy items, keep drains clear, and sweep regularly to remove grit that can wear the surface. Avoid acidic cleaners on coatings and tile grout. Check door threshold seals and railing bases after each monsoon. With this simple care, a well-built terrace system remains cool, dry and attractive for years.
If your terrace tiles are sound and you mainly want lower heat with quick work, a coating system is usually best. If tiles are broken, hollow or badly sloped, or if you want maximum thermal performance with a premium finish, retiling over insulation and waterproofing is better. During inspection, we tap-test tiles, check slopes and look at ceilings below to recommend the option that solves the real problem rather than just covering it.

On a sunny afternoon, a terrace slab collects heat from direct sunlight and also from hot air and reflected glare from surrounding walls. Dark tiles and bare cement absorb most of this energy. The heat conducts down through the tiles, the mortar bed and the concrete slab, and the ceiling of the room below becomes warm, then hot. Because the slab is thick and heavy, it continues releasing this heat for hours after sunset. Terrace walls facing west add to the load in the late afternoon. Terrace heatproofing interrupts this path at the top, either by reflecting sunlight away with a bright surface or by inserting insulation that slows heat before it reaches the slab. The result is a ceiling that stays closer to room temperature, so fans and air conditioners in the room below can actually keep it comfortable.
In many households, especially in southern Punjab, families still sleep on the terrace during the hottest nights, or use terrace rooms as summer bedrooms. A heat-soaked slab makes both uncomfortable because it radiates warmth all night. After heatproofing, the terrace surface cools much faster after sunset, and the rooms beneath no longer feel like ovens at midnight. This simple change can make a real difference to sleep quality and health during long heatwaves.
Many terraces also carry water tanks, solar panels, inverter batteries in cabinets and AC outdoor units. These fixtures create shadows, stands and fixings that need careful treatment. We coat or seal beneath and around stands, protect cables, and place rubber pads under tank bases where possible so the new surface is not crushed. If fixtures can be temporarily moved, we coat underneath them for full coverage; if not, we detail neatly around them to maintain a continuous waterproof and heat-reflective layer.
Terrace work is best done in dry weather, ideally in spring or after the monsoon. Since the terrace is often a busy family space, we plan the schedule with you, keeping a path to water tanks open where needed and advising how long to keep people and furniture off each area while it cures. Large terraces can be completed in sections so part of the space remains usable.
If you are retiling, the colour of the tiles matters as much as their design. Dark red, brown and grey tiles absorb far more sunlight and become very hot underfoot. White, cream and light beige tiles reflect more and stay noticeably cooler. Matt or lightly textured finishes reduce glare and slipping, while glazed white tiles can be too bright and slippery in direct sun. We help you choose a light, practical tile that suits both the heat and the look of your home, and fix it over a waterproofed, insulated bed so the whole terrace works together.

Terrace heatproofing is a treatment for open terraces and rooftop decks that reduces heat entering rooms below while providing a durable, walkable surface. It may use a traffic-grade reflective coating or insulation beneath new light-coloured tiles, always combined with careful waterproofing.
Yes. Our terrace systems are designed for normal foot traffic, furniture and daily use once fully cured. We advise using pads under furniture and avoiding dragging heavy items to protect the surface.
Often yes, if the existing tiles are firmly bonded. We clean them, repair grout and apply a compatible primer and coating. If tiles are hollow or broken, removal and a new insulated, waterproofed build-up is the better choice.
Smooth coatings can be slippery when wet, so for walkways and areas near doors we can add an anti-slip texture. Tiles can also be chosen with a matt or textured finish.
Usually because the threshold is low, the slope runs toward the door, or the joint between floor and frame has cracked. We seal and detail thresholds and, where possible, adjust slopes so water drains away from doors.
Yes, with care. Place pots on stands or trays, keep them away from drains and avoid overwatering. Built-in planters should be waterproofed separately with root-resistant detailing.
