How a Roof Vent Is Installed on a Tiled Roof
Short answer: a roof vent is fitted by removing one or two tiles at the chosen position, cutting an opening through the sarking, fitting the vent onto a flashing or tile adaptor that sits under the surrounding tiles, sealing it into the sarking so water cannot track underneath, and re-laying the tiles around it. On a tiled roof the flashing detail matters more than the vent itself — it is where leaks start.
How a roof vent is installed, step by step
- Work out where it goes. Ventilation only works if air can move through, so a vent needs to sit high on the roof, usually within a metre of the ridge, with intake at the eaves. One vent in the wrong place does very little.
- Check what is underneath. Rafters, battens and any wiring or ducting. The opening has to fall between rafters, not through one.
- Lift the tiles. Usually one or two, plus the surrounding course so the flashing can be tucked under. Tiles are lifted, not broken — they go back afterwards.
- Cut the sarking and the opening. Sized to the vent throat. The sarking is cut and dressed, not just punctured, so water running down it is directed away rather than into the opening.
- Fit the flashing or tile adaptor. This is the part that keeps the roof watertight. It sits under the tiles above and over the tiles below, so water runs over the top of it. On a terracotta or concrete profile it needs to match the tile shape.
- Mount and seal the vent. Fixed down, sealed to the flashing, and on a solar unit the panel is angled for sun.
- Re-lay and repoint. Tiles back, pointing made good where it was disturbed.
- Test it. Check the fan runs, and check for daylight or gaps from inside the roof space.
Why this is not a good DIY job on a tiled roof
We are a roofing company, so take this with that in mind — but these are the three things we get called out to fix after a vent has been put in by someone else.
Cracked tiles. Terracotta and concrete tiles crack under foot, and the damage often is not visible until it rains. Walking a tiled roof without knowing where to put your weight is the single commonest cause of the leak people then need repaired.
Flashing done wrong. If the flashing sits on top of the tiles instead of under the course above, water runs behind it. It may not leak in ordinary rain and then leak badly in driving rain, which makes it very hard to trace later.
Sarking left open. A hole cut in the sarking without dressing it turns the membrane from a second line of defence into a funnel.
There is also the warranty question. Both manufacturers we install require work to be carried out in line with their installation guides, and a penetration cut badly through tiles and sarking is the kind of thing that gets a claim declined. See our FAQ on warranties.
Which type of vent?
We fit all of them, and the right one depends on the roof and what you are trying to fix.
Whirlybirds are wind driven, cheap, and need no power. They move less air than a powered unit but there is nothing to fail.
Solar vents run a fan off a small panel, so they move considerably more air and cost nothing to run. Best on a roof with good sun.
Internal roof ventilation systems are ducted and extract from specific areas. Worth considering where condensation or a hot upstairs room is the actual problem rather than general roof heat.
Does your attic mimic a sauna during the summer months? Are you tired of freezing in winter and paying high energy bills?
If so, your problem might be poor attic ventilation. Among the most popular remedies is the use of a solar roof vent.
These gadgets are not only effective at ensuring comfort indoors but also saving considerable amounts of energy.
This article highlights some of the main reasons why you should consider fitting a solar roof vent .
What are solar roof vents?
Solar vents contain a solar panel that transforms sunlight into electricity unlike standard wind-dependent ones. Subsequently, the fan uses this electrical energy to forcibly extract stagnated hot air from the attic and bring in new cold air from outdoors.
- Panel: It is placed on top of your house and collects power from the sun.
- Electric fan: This appliance depends on the power made by the solar module. It removes hot air.
- Ducting (Optional): In some cases, ducting channels the airflow for more targeted ventilation.
A solar roof vent creates continuous air circulation hence offers several benefits over conventional types.
Why Should You Consider A Solar Roof Vent ?
Energy Efficiency and Cost Savings
Traditional electric attic fans consume power, leading to higher utility bills on your part.
On the other hand, solar-powered units use free and abundant sunshine thus reducing overall home energy consumption. Consequently, electricity costs are lower especially during summer when cooling needs are highest.
Improved Home Comfort
A Solar Roof Vent plays a critical role in controlling attic temperature. Sometimes attics get extremely hot during summer with temperatures reaching 150°F or even more.
This high heat may infiltrate living spaces thereby making your house uncomfortable and straining the air conditioning system.
Solar-powered fans expel warm air from the attic hence keeping the indoor environment cooler throughout the year. In winter they help remove moisture-laden air which can cause condensation and mould growth.
Environmentally Friendly
These environmentally friendly devices function as substitutes for conventional ventilators since they harness clean renewable power generated by sunlight.
So a solar roof vent does not rely heavily on fossil fuels which emit harmful greenhouse gases into the atmosphere thereby contributing towards global warming.
As awareness about environmental conservation continues to spread among individuals globally, more homeowners will adopt various renewable energy resources like these hence cumulative ecological impact shall be quite significant over time.
Prolonged Roof Lifespan
Roof materials deteriorate over years due to different factors such as heat and moisture. High temperatures cause shingles to crack while dampness leads to rotting and mould growth.
Regulating attic temperature is one way of dealing with these problems which is achieved by installing solar roof vents.
By expelling hot air from the attic space and reducing moisture content, a solar roof vent helps in maintaining balanced conditions within your roofing system thereby extending its lifespan thus saving you money for expensive repairs or replacements.
Increased Property Value
Your property’s value may rise if you choose to invest in solar technology. Energy-saving houses with sustainable elements are becoming more popular among potential customers.
A solar roof vent is a good-looking extra that can make your house special on the housing market. It implies a dedication to saving electricity and living in an eco-friendly way, thus becoming more attractive for buyers who care about the environment.
Low Maintenance and Durability
Solar roof vents are built to last long and require very little maintenance. They often use strong materials that can withstand severe weather conditions.
Since they have fewer moving parts than electric vents do, they are less likely to break down mechanically as well.
Moreover, most of them come with warranties that guarantee their performance over an extended period thereby giving homeowners peace of mind regarding this issue. You can consider integrating them to your roof during New Roof Installation.
Easy Installation
Installing a solar roof vent is quite simple and can be done by any qualified professional within hours. There is no need for extensive wiring or modifications to your home’s electrical system as such things might be required by other types of vents installation methods .
This ease of installation makes it perfect for those who want quick results in improving their house ventilation system without necessarily spending too much money on labour cost or waiting longer than necessary due to complicated procedures involved during its setup process.
