Many of us have garages that are in a state of disrepair, to say the least. Whether you’ve got mice running around, or leaks that you’ve given up even trying to stop coming in, at some point, it is something that you’ll have to deal with.

In many cases, what’s needed is to just replace the garage roof. Here, we take a look at some of the different factors that will go into determining how much that process will cost, from material costs to waste disposal.

Assessing your existing roof

Before you can put a new roof on, you’ll need to assess and get rid of your existing one. This is where the first unexpected cost might pop up - it’s very possible that your current roof contains asbestos. 

As asbestos is highly carcinogenic, you’ll need to first get the roof material tested, and then if the test comes back positive, you’ll need to pay to get it removed professionally.

The cost to remove an asbestos garage roof will depend on a number of factors, including what kind of asbestos it is, where the garage is located, and how large the garage is. It’s important not to cut corners in this area - getting things wrong could result in serious damage to your long-term health.

Labour

One of the biggest costs to factor in is labour, as hiring a roofing contractor ensures the job is done professionally and safely. The total expense will vary depending on factors like your location, the complexity of the job, and the type of roof you choose. To avoid overpaying, it's a good idea to gather multiple quotes and compare prices. Checking reviews or asking for recommendations can also give you confidence in the quality of work you’ll receive.

While some may consider a DIY approach to save money, this can be a risky decision if you lack experience or the right tools. Roofing work involves handling heavy materials, working at heights, and ensuring proper waterproofing as mistakes can lead to leaks, structural damage, or even personal injury. In the long run, hiring a professional may save you money by preventing costly errors and ensuring a high-quality, durable finish.

Materials

In addition to labour, you’ll need to think about the cost of the roofing materials. If you go for a glass roof, for example, it’ll cost substantially more than if you go for a wood frame with a roofing felt on top. Materials do change in price quite rapidly nowadays with so many geopolitical events going on, so even if you thought you had a good idea of how much something like plywood cost a few years ago, it’s important to get a new quote so that you’re not left surprised.

Consider the longevity of your new roof

When trying to keep the cost of your new roof as low as possible, it’s important to think about how long it’ll last. While you might be able to save a little now, if that means that you’ll need to replace it again in ten years, or that the new roof starts leaking straight away, it’ll likely be a false economy. 

These are the main factors that will go into the cost of your new garage roof, but clearly, each one depends on multiple sub-factors. You’ll need to get quotes from multiple parties for labour, waste disposal and materials before you can get a precise answer on how much it’ll cost.
