Roof Ventilation – Does it Really Work?

Roof ventilation is, in theory, supposed to increase the flow of air throughout your attic. This system will reduce humidity in your attic; thereby, preventing a buildup of mold within your walls and improving the quality of air throughout your home. While it’s a great idea, there’s a lot of debate as to whether or not it actually works. But lucky for you, we have the truth.

Below, you can read all about whether or not roof ventilation actually works.

Does it work?

In short, roof ventilation can work, but people often do it wrongly. Not only this, but roof ventilation is actually the same for every home and the roof rarely has anything to do with it. Most often, the reason why roof ventilation doesn’t work is because the ceiling isn’t airtight.

Before you go through this, though, your attic should be completely cleared of anything except your insulation. If you have stuff in your attic, your insulation can be moved around easily and can reduce the efficiency of your roof ventilation.

How can it go wrong?

The reason why roof ventilation is often done wrongly is because there are people who simply don’t follow the instructions. They simply drill holes into the ceiling, which they fill with recessed lights and install a series of mechanical systems.

The problem with doing this is that when they stuff the drilled holes with recessed lights, air is able to leak through. In colder temperatures, these leakages can lead to a buildup of humidity in the attic that’s worse than if you hadn’t installed the ventilation in the first place.

Of course, because it’s cold during this time, your home will be colder and you’ll be wasting energy and heat by trying to make up for the cold air coming in.

Another problem is that if you get a professional to do it, he or she might not know to air-seal all of the areas that need to be sealed. If you aren’t a professional in the area, then you also won’t know if they’ve done it.

Some people try to fix the leaks with duct tape, and it seems to work for a short while, but duct tape isn’t always effective. You can cut down on how much air is coming in, but you can’t remove the leakages altogether.

How to make it work

If you want to make it work, you need to make sure that your attic and roof is as minimalist as possible. This is especially true if you’re trying to ventilate your roof deck. It’s practically impossible to do if you have any skylights, valleys, hips, or dormers because these will interrupt the rafter bays. You need to have at least one inch of space between the top of your insulation and the back of your roof sheathing. You should be aware, though, that if you live in a colder climate, it’s easy for snow to enter the ridge vents and cause rot in your attic and roof. Over time, this rot will increase throughout your home and can cause cave-ins, as well as other problems that will cost you more money in the long-run.


Are you thinking about ventilating your roof? Have you heard horror stories about roof ventilation that goes horribly wrong? If so, then you’ve come to the right place. Plenty of people ventilate their roof wrongly and it doesn’t work at all, which is why some decide not to do it at all.

In the above guide, we teach you about how to make your roof ventilation work and why it goes wrong so often.

How To Maintain Your Slate Roof Tiles

How often do you look at a person’s roof? The answer would surprise you! Over 60% of individuals always stop and take a look at the roof of a house. However, what many don’t realise is the type of material that is used for the roof. There is a bit of confusion about which material is used. Except one. Everyone knows slate roofs and everyone can tell when a house has one.

As amazing as these roofs are – and they are the best you can buy; guaranteeing you years of durability, everlasting style and strength against Melbourne’s changing weather – looking after these roofs can take a bit of effort.

So if you are looking to get slate roofs in your home, or if you have them already, we have the tips for maintaining these stunning tiles.

Tip 1: Check It Yourself

Sometimes all you need is a quick glance at your roof. Now and then (after the Winter or Summer months), take your time and check your roofs. Stand back from your house and take a glance at the condition of your roof. You will be able to tell from a distance if any problems or issues could be happening.

Tip 2: Look At Your Guttering

One of the most ignored sections of a roof – and one of the most pivotal – is your guttering. Letting your gutters overflow with gunk and debris will put unnecessary pressure on your roof. Nothing will happen right away because of the durability of the tiles, but over the years – especially if you leave it – will make the roof weaker. If you are noticing your gutter struggling under the weight, then look to get a gutter replacement from a professional.

Tip 3: Look Internally

Sometimes you will know there are problems with your slate roofing because of what is happening inside your home. Water drips, dips in the roof or leaks are a vital sign that there are problems in your roof. Check out your ceiling now and then to see if any problems are developing under the ceiling.

Tip 4: Speak To Professionals For Regular Inspections

There is no harm to get a professional roofing contractor to come over and look at your slate roof once in a while. They have eagle-eyes and can notice if there are any little or developing problems in your roof. From there, they can provide you with sound advice on what to do next and how you can manage it. How often and when should you look to bring a professional? A once a year check-up is best and always after summer or winter, as they are the most weather intense months.

We hope that these tips will help keep your slate roof in the best condition. If you would like more information or help with any roof repairs or restorations, speak to Melbourne’s best in Big Apple Roofing today.

You have to ask them the right questions, so you know can trust them to do the work for you. To make it easier for you should look to get these following questions answered by the specialist.

Ask for an estimate

It is always advisable to first get a clear understanding of the cost that would be incurred by getting a specialist to repair your roof. Different roof repairers may have different techniques which may differ the cost of repair. You probably don’t want to end up by spending a fortune for just a tiny repair to be mended. Therefore it is also important that you find out what is wrong with your roof and ask the specialist to give you a quotation of how much it would cost along with his labour cost as well.

Who will be handling the actual work? 

Roof repairing or installation is not an easy and straightforward task. It requires a lot of methodical work which only experts should put their hands into it. Therefore it is important that you inquire about who is going actually going to do the installation or repairing. This way, you will have a firm grasp on the person that is doing the work for you, rather than someone that you don’t know.

Inquire the roofing cost per square foot

There would be so many roof repairing experts who have their own expenses and reasons for it. Every repairer is surely going to put in a lot of time, skill, quality of work, speed and also money to make your roof return to its best. Therefore it is important you inquire about the cost or charges of each square foot. This would give you an idea on how to prepare a budget for the repairs or even help you to rationalise your budget by searching for some other repairers. Inquiring about the cost per square foot will give you an overall idea of how much it would cost you to get your roof repaired.

Inquire whether a roof layover is possible instead of a full replacement

A roof layover means that the current roof would not be taken off and another roof would be laid over the old one. By inquiring with this question from the repairing team, it would give you an idea of how genuine their work is or if they just want to earn a buck by satisfying you. A roof layout can be dangerous, so you probably want a roof repairer to come over because you have an issue with your roof. And by covering it up with another layer will only make things worse and not better.
