Find out how to replace your garage roof with bitumen roof sheets with our below guide. Suitable for all DIYers! 

Is your garage roof leaking? Is it time to replace it and make it more weather-proof and watertight? If so, you’re in the right place as we’ve created a DIY guide suitable for all skill levels to help you replace your garage roof with bitumen sheets.

Garage roof sheets

Let’s start by looking at some of the different types of roof sheets you could install on your garage roof and why we would recommend bitumen roofing overall.

Metal roofing sheets

Metal roofing sheets are a popular choice as they can withstand extreme weather conditions and are lightweight. However, they can be very loud and noisy and can dent easily. Therefore, if you need to be able to stand on some of the sheets to install others, they may not be the most DIY-friendly solution. They also tend to be more dangerous to install than most other roofing sheets.

Plastic roofing sheets

PVC or polycarbonate roofing sheets are also a very popular choice as they are both durable and lightweight too. They also allow lots of light in but filter out the sun’s UV rays making them ideal for greenhouses as well. However, not all plastic roofing sheets are scratch-proof and they can be more expensive than other roofing sheets - although they are typically more cost-effective than metal sheets.

Bitumen roofing sheets

The most affordable option, bitumen roofing sheets share many of the same benefits as metal and plastic but can also be considered as a better alternative. For example, not only are ours lightweight, durable and can withstand extreme weather conditions, they are also noise-reducing, UV-resistant, made from 50% recycled materials, and can be stood on top of as long as the load is spread using a crawl board. They’re also virtually maintenance free and super simple to install making them the most DIY friendly, durable, cost-effective garage roofing solution!

We also have a wide variety of bitumen roofing sheets with different colours and styles available. You can check out some of ours in our “Which shed roofing sheets are the best?” blog where we have compared the benefits and drawbacks of each or you can view our full product range here.

Corrugated roofing sheets

You may have noticed that almost all of our bitumen roofing sheets are corrugated and whilst your garage roof doesn’t have to have corrugated roofing, there are some benefits you just can’t ignore, the biggest being that the corrugations add extra strength and durability without adding extra weight to your roof.

The corrugated shape also allows rainwater to flow off easily and it results in a larger surface area meaning they can withstand falling objects and offer more protection during storms and harsh winter weather. Our bitumen sheets are also super resistant to heat and are installed across the world in countries such as Brazil, Columbia, Malaysia, India and China. Perfect for our unpredictable UK weather.
