Factors That Impact Garage Roof Replacement Costs
Several factors influence the cost of a garage roof replacement, and knowing what they are will help you budget for your roof costs before your project begins.
Garage Size and Roof Shape
As you might expect, larger garages cost more. This is because more materials and labour are needed to complete the job.
The shape of the roof is also factored into things, as flat roofs are generally simpler and cheaper to replace than traditional pitched roofs.
Type of Roofing Material
Material choice has a big impact on the cost of replacing a garage roof.
- Felt tends to be an affordable, budget-friendly option, but it’s not as long-lasting or durable as other options.
- EPDM and GRP fibreglass have a higher upfront cost, but they last a lot longer, making them a better long-term investment.
The material you choose affects both the replacement price and the cost of roof maintenance going forward.
Ease of Access and Height
If the garage is detached and easily accessible, labour costs will likely be lower, as the job will be relatively straightforward.
However, if scaffolding is needed or if the garage is difficult to access, you should expect the price to increase to account for the additional labour and complexities.
Location in the UK
Garage roofing costs differ depending on where you’re based in the UK.
You’re likely to find the cost higher in London, the south east, and busy cities, as this is where labour costs are highest. This is why our garage roof cost calculator takes your location into account when providing a quote.
Urgency and Weather Conditions
Sometimes, you can plan to have a garage roof replaced ahead of time, but that’s not always the case.
If you need the job completed urgently - for example, due to storm damage or a serious leak that can’t be ignored - you should expect to pay a premium for a quick turnaround.
Poor weather conditions also need to be factored in, as rain, ice and storms can extend the timeline, which could increase the overall cost.
Choosing the Right Roofing Material
There’s a lot to think about when you’re planning a garage roof replacement, including choosing the right material.
To ensure that you’re striking the perfect balance between cost, durability and visual appeal, you need to weigh up all of your options.
Felt Roofing
Felt is one of the most affordable material options, and it’s often used on flat garage roofs.
It’s quick to install and provides a waterproof finish, though it doesn’t tend to last as long as other materials.
EPDM
EPDM is a flexible and durable rubber that’s commonly used on flat garage roofs.
It can last for decades, it’s water-resistant, and can withstand extreme weather.
Fibreglass
Fibreglass offers a sleek finish, minimal maintenance and boasts a long lifespan.
Though the fibreglass roof cost isn’t the cheapest, it does offer long-term value and longevity.
Clay or Concrete Tiles
Tiles are commonly used on pitched roofs.
They create a more traditional look, lasting for many, many years with the right maintenance.
However, they are heavier and more expensive than other roof material options, which means they’re only suitable for garages with a strong structure.
Tips to Lower Garage Roof Replacement Costs
Replace the Roof During Dry Months
As long as the replacement isn’t urgent, consider scheduling your project during the spring or summer.
This will help you avoid weather delays and additional costs related to wet or cold conditions.
Roof replacements tend to be completed quicker in drier weather, which can reduce labour time and cost.
Get Multiple Quotes
It’s important to compare quotes from multiple contractors, as this will help you find the best price.
You don’t want to pay too little and risk being left with a subpar finish, but you also don’t want to pay more than you need to.
Combine with Other Home Improvement Jobs
If you're planning other exterior upgrades - for example, if you’re having your guttering cleaned or fascia boards capped - consider combining the jobs with your roof replacement project.
You might find that some contractors offer discounts for combined work, and you’ll benefit from not having to handle the admin of hiring multiple people.
