3 Reasons to Have Your Garage's Corrugated Metal Roof Replaced

Posted on: 17 August 2022

If your home has a garage that was not constructed within the last few years, there is a good chance that it is fitted with a corrugated metal roof. Corrugated metal roofing was widely used in constructing garages and other types of outbuildings for many years, largely because it is both affordable and reasonably durable.

However, if your garage still has a corrugated metal roof, it may be a good idea to have it replaced with more modern metal roofing, even if the roof seems to be in decent shape. Here are three reasons to have your garage's corrugated metal roof replaced by a professional metal re-roofing service:

Improved Heat Insulation

Most corrugated metal garage roofs were fitted before climate change became such a pressing issue, so they generally aren't fitted with any kind of integrated heat insulation. An uninsulated corrugated metal roof can allow your garage to become stiflingly hot during the summer months.

This is especially problematic for attached garages, as the heat that builds up in your garage can leak into your home, substantially raising your air conditioning bills. A detached garage that gets too hot can also cause problems if you spend a lot of time inside, working on vehicles or hobbies.

Most modern metal roofing products are fitted with some kind of integrated heat insulation. Some products have insulated foam backing, while others have hollow cores filled with insulation material. Having your corrugated garage roof replaced with one of these products can help keep your garage cooler, without relying on fans or energy-hungry air conditioners.

Protect Against Leaks

The unique design of corrugated metal roofing is not compatible with the hidden fasteners used to construct many modern metal roofing products. As a consequence, corrugated metal garage roofs have exposed fasteners, which are notorious for causing leaks in older roofs. If your garage's corrugated roof has been in use for many years, it will probably start to leak in the near future, if it hasn't done so already.

Replacing your garage's corrugated roof with new metal roofing will minimise the chance of leaks, giving your vehicle(s), tools and equipment better protection against the elements. Standing seam metal roofing is particularly prized for being extremely leak-resistant, and is attached using hidden fasteners that are virtually immune to leakage.

Remove Hidden Asbestos

Many older corrugated metal roofs were manufactured using asbestos or asbestos by-products. If your garage's corrugated metal roof has not undergone significant repairs or restoration since it was fitted, it may still contain large quantities of deadly asbestos. If this asbestos is ever accidentally disturbed, it can put you and your family at serious risk.

If you are unsure whether your old corrugated garage roof contains asbestos, it may be best to play it safe and have the roof professionally replaced. Modern metal roofing does not contain asbestos or any other potentially harmful substances, such as lead-based paint. Reach out to a local service provider to learn more about metal roof replacements.
