Why Roof Ventilation Is So Important?
Water dripping on insulation
Damaged insulation
Damaged rotten timbers
Normally we only think about roof ventilation when we have an issue.
Perhaps you’ve gone to get your suitcases out of the attic only to find they’re covered in mould, or you’ve noticed condensation on the roofing felt, or roof timbers etc.
If that’s the case you need to do something NOW!
Condensation in your attic will not only cause damage to anything you’ve stored up there but it can get inside your attic insulation reducing it’s effectiveness, and once your insulation is damp you’ll struggle to dry it out.
If it gets really bad condensation can eventually saturate your insulation (especially if the condensation is constantly dripping in one location). This will lead to damp patches appearing on the ceilings below.
Even if your roof seems ok, it’s worth checking to make sure you’ve got adequate ventilation in order to avoid potential issues in the future.
BENEFITS OF PROPER ATTIC VENTILATION
Prevent MoUld and Moisture Damage
Increase Your Roof’s Lifespan
Reduce Energy Costs
(During summer months)
If you’ve got condensation issues in your attic it’s now relatively easy to resolve by adding additional attic ventilation. Please don’t ignore any issues you may have as they’ll only get worse (and more expensive to fix) the longer you leave them.
Try to establish where the water vapour is coming from and if you can stop it from getting into the loft great. But if you can’t installing additional roof ventilation isn’t as difficult as it might sound.
Why Would the Standard Ventilation Not Work?
The roof ventilation built into your house would have been adequate at the time of construction.
However, if you’ve added anything that could have made the attic area cooler (such as increasing attic insulation) or reduced the effectiveness of the existing ventilation (such as fitting attic insulation or external wall insulation that partially or entirely blocks existing vents) then you’ll probably need additional ventilation.
Why Has Attic Ventilation Become a Hot Topic in Recent Years?
In the past our homes were poorly insulated and pretty draughty. So water vapour rarely got a chance to build up inside as it was replaced by fresh air coming in via these draughts. Meaning it was removed before it got a chance to create any problems.
At this time attic areas were also warmer than they are today as very few would have been insulated. So any heat in the house would rise up and warm the attic area making it less likely that any water vapour that hadn’t been removed by the draughts in the house would condense in the attic.
Now, however, we all want to reduce our heating costs and keep our homes as warm as possible for as long as possible. So we insulate the walls and attic and reduce the draughts through the fabric of our home by fitting modern windows and doors etc.
These measures may be great for reducing the running costs of our house and helping it stay warmer for longer. However, all this extra insulation means the attic area (above the insulation) is now cooler as the heat is trapped in the rooms below.
Plus we typically just roll out insulation in our lofts without fitting a vapour barrier, sealing around wires for lights and our roof hatches are often ill-fitting.
So what’s wrong with that I hear you ask?
These small gaps will allow water vapour to get up into your freshly insulated attic area, where it can come into contact with lots of cold surfaces.
Any water vapour that does get into your attic is now at greater risk of condensing on the underside of your roof cover or any other cold surfaces it comes into contact with.
To reduce the chances of condensation you need to increase the ventilation in your attic to try and get rid of any water vapour that may be present, before it manages to condense.
Common things that could increase the risk of condensation in your attic:
Increasing the level of insulation in your attic without providing additional roof ventIlation.
Fitting insulation over existing soffit vents.
Excessive water vapour from your house getting up into the attic. Possibly via gaps around light fittings, spot lights, services or a poorly fitted attic hatch.
Header tank in attic is warm causing water vapour to vent into the loft (this is a job for a plumber).
Bathroom extractor fans not vented correctly.
Check your soffit vents!
Soffit vents are not as affective as roof tile vents. Also, quite often they are blocked by old timber soffit board (fake soffit vents), attic or wall insulation.
SEAI
Attic Insulation Grant
In order to get an SEAI attic insulation grant, you have to make sure your house has roof ventilation that meets Irish Part L of the Building Regulations.
How Many Roof Vents Do I Need?
A standard Irish 3 bedroom semi-detached house requires 6 roof vents.
3 at the front of the house and 3 at the back of the house.

** You may need additional vents for bathroom extractor fans.
Extractor Fan Connection
The correct way to vent a bathroom fan through an attic is to terminate the vent to the roof .

FAQ
How Many Roof Vents Do I Need?
A standard Irish 3 bedroom semi-detached house requires 6 roof vents.
3 at the front of the house and 3 at the back of the house.
(1 roof tile vent every 2 meters.)
** You may need additional vents for bathroom extractor fans.
How long it takes to install the roof vents?
It usually takes less than 1 hour to install the vents for an average 3 bedroom house.
Why install roof vents?
Installing roof vents moderates the temperature in an attic or roof space. By preventing a roof space from getting too hot or too cold you reduce the build-up of moisture levels. Allowing the air in a property to circulate keeps the air fresh and reduces the risk of condensation.
Can't I just do the work myself?
Most roof work should not be do-it-yourself. Professional roofing contractors are trained to safely and efficiently install the vents. Those with less experience can harm a roof with improper roofing, techniques and severely injure themselves by falling off (or even through) a roof in need of repair.
