Is it time to replace your corrugated garage roof?

If you have a corrugated garage roof, you might be wondering if it needs replacing. The signs are usually visible – the damage is wide spread and often irreparable. If you are unsure, our advice is to get a roofing contractor to inspect your roof and give you their expert opinion.

You also have to remember that many corrugated garage roofs can have asbestos, so they must be handled with care. Any professional tradesman will be able to give you a full report on this and their recommendations.

To help you decide if your corrugated garage roof needs replacing, we will take you through some of the tell-tale signs to look out for.

Signs that your corrugated garage roof may need replacing

One of the first things you need to consider is age – although you might not even know how old your corrugated roof is. As it gets older, your corrugated roof will need replacing as it starts to fall apart. One of the most common indicators that your roof is on its last legs is patches or streaks of rust, particularly where the sheets of iron overlap or around nail holes. A patch of the roof may collapse if weight is placed upon it – i.e. someone walks across the roof. If you do decide to inspect your own roof take this into account, any weight placed upon a fragile roof will cause it to break. The last thing you want to do is injure yourself, so take care or call in an expert.

You should also look out for small patches of rust throughout the roof – this is usually a good indicator of extensive rust damage. Watch out for loose nails, again this is another sign that your roof probably needs replacing. As the nails begin to loosen, moisture is able to get into the loose nail and collect in the nail hole, causing damage to the timber structure.

Another sign that your roof needs replacing is noise. When it’s windy does your corrugated garage roof make a banging noise or do sheets or iron flap around in the wind? If so, this is a sign that nails are lifting and this is a problem which will only get worse. As your roofing structure becomes more unstable, you increase the chances of having water leaks. Corrugated sheets can even be blown away by the wind causing external damage.

On this list we can include leaking, dampness, mould and discolouration – all these signs indicate that its time to get your garage roof checked out by a professional.

What about asbestos and corrugated garage roofs?

Many corrugated garage roofs actually have asbestos in them, although it is likely to be of a low grade asbestos. You should always be cautious when it comes to asbestos, as it can be dangerous to your health.

If you do think your garage roof might have asbestos, the best thing to do is not to distrub it. Seek professional advise and get someone who is qualified to remove asbestos for you.

What is the solution?

When your garage roof is beyond repair it will require a brand new corrugated roof to be fitted. There are a number of steps to carry out before your roof can be fully replaced.

Step 1 – The old roof will have to be removed and deconstructed carefully if asbestos is found to be present. It will have to bagged and disposed of correctly to ensure the proper safe removal of asbestos from your property.

Step 2 – Some repairs may need to be carried out on the existing timber frame before the new roof can be fitted. Sagging, cracks and/or broken timbers are replaced or braced, so they are ready to carry the load of a new roof for years to come.

Step 3 – Start putting on the new roof now that the timber structure is secure. Our job is to ensure the roof is well supported and durable, and that it won’t be damaged if it is required to carry weight or be walked on at some point in the future. The end result is a roof you can be proud of and that will last for years to come. That will stand the test of time and be durable enough to contend with the winter weather.

So there you have it, look out for the signs we have mentioned in this article to decide if your corrugated garage roof needs replacing. If it does, remember to hire someone who is qualified and able to deal with asbestos – the end result should always be of a high standard that you are satisfied with.
