00VILLA GUIDE
Checking the equipment on a villa roof
The roof of a villa is a plant room in the sun: AC condensers, water tanks, sometimes solar panels or water heaters, and the drains and membrane that keep rain out. Because nobody goes up there, problems develop unnoticed — dusty condensers, cracked tank lids, blocked drains, damaged waterproofing around equipment plinths. A periodic, safe look catches them early.
01PART
AC condensers
Dust and sand on condenser coils reduce cooling and raise bills. Look for bent fins, debris against the unit, loose panels and oil stains near pipe joints that can mean a refrigerant leak.
- Check coils for dust.
- Look for oil stains at joints.
- Clear debris around units.
02PART
Tanks
Tank lids must seal, overflows and vents need screens, and the shell should not be cracked or chalky. Insulation jackets degrade in the sun.
- Check lids and seals.
- Look at overflow and vents.
- Inspect shell and jacket.
03PART
Membrane and drains
Technicians walking to equipment damage the waterproofing. Look for blisters, cuts and lifted seams along access routes, and clear drains of sand.
- Inspect access routes.
- Clear roof drains.
- Check around plinths.
04QUESTIONS
- Is it safe to go on the roof?
- Only with safe access and edge protection; otherwise leave it to a technician.
- How often should roof equipment be checked?
- At least twice a year, and after storms.
- What do oil stains mean?
- They can indicate a refrigerant leak at a joint.
- Can walkways protect the roof?
- Yes, protective pads along routes help.
- Do solar panels need checking too?
- Yes, where fitted. Dust reduces their output, and their fixings and cable routes cross the roof waterproofing.
