Getting a new roof is a big decision. Whether it’s your first time or you’ve done it before, there are always questions. At Roofing Newcastle, we’ve heard them all. From the basics to the more unusual, homeowners want to understand what’s involved, how long it takes, and what it’s going to cost.
This guide brings together the most common questions we get asked about new roofs. It’s honest, straightforward, and based on real experiences from roofing jobs across the North East.
If you’ve ever wondered what actually happens during a roof replacement, what materials are best, or how to tell if your roofer is reliable, keep reading.
Do I really need a new roof?
Not always. Sometimes repairs are enough. But if your roof is over 20 to 30 years old, showing signs of sagging, leaking regularly, or missing large patches of tiles, a full replacement is often the smarter long-term choice.
At Roofing Newcastle, we carry out a detailed inspection before recommending anything. We’ll tell you if a repair will do the job or if it’s time for a full replacement.
How much does a new roof cost in the UK?
It depends on the size of your roof, the materials you choose, and the complexity of the job.
As a rough guide:
- A small terraced house might cost between £3,000 and £5,000
- A semi-detached home may range from £5,000 to £8,000
- A large detached house can cost £8,000 to £15,000 or more
Slate roofs and more complex shapes increase the cost. Flat roofs tend to be cheaper.

How long does it take to install a new roof?
Most roof installations take between two and five days. Smaller jobs can be done in one day. Larger or more complex roofs may take up to a week or longer.
Weather can affect the timeline. Rain, high winds, or cold temperatures may delay work for safety reasons.
What’s included in a full roof replacement?
A full roof replacement usually includes:
- Scaffolding and site setup
- Removing the old tiles, battens, and underlay
- Inspecting and repairing the roof structure
- Fitting new breathable underlay and battens
- Installing new tiles or slates
- Adding ridge tiles, flashing, and ventilation
- Clearing away waste and carrying out a final inspection
We also issue a warranty and compliance certificate when required.
Do I need planning permission to get a new roof?
Most roof replacements do not require planning permission, as long as you are not changing the shape, height, or material of the roof.
You may need permission if:
- You live in a conservation area
- The property is listed
- You are making structural changes
- You are adding large roof windows or dormers
Check with your local council or ask Roofing Newcastle for advice.
Does my new roof need to comply with building regulations?
Yes. Even if planning permission isn’t needed, the roof must meet UK building regulations. These cover insulation, ventilation, fire safety, and structural strength.
If you’re replacing more than 25 percent of the roof area, you’ll usually need to notify building control.
At Roofing Newcastle, we’re registered with a Competent Person Scheme, which means we can self-certify our work and handle this for you.
Can I stay in the house while the roof is being replaced?
Yes. Most people stay in their homes during the work. It will be noisy during the day, and parts of the garden or driveway may be blocked off, but it’s safe to remain inside.
If you work from home, have small children, or sensitive pets, you might want to stay elsewhere for a couple of days.
How do I know which roofing material is best for my home?
Each material has pros and cons. The right one depends on your budget, the style of your home, and what local planning rules allow.
- Slate is long-lasting and traditional but heavy and expensive
- Concrete tiles are affordable and versatile
- Clay tiles offer character and durability
- Synthetic tiles are lightweight and easier to install
- Flat roofs may use felt, GRP fibreglass, or rubber
Roofing Newcastle offers clear advice based on your property type and goals. We’ll bring samples so you can see and feel the difference.
How long will my new roof last?
Lifespan depends on the material:
- Natural slate: up to 100 years
- Clay tiles: 50 to 80 years
- Concrete tiles: 40 to 60 years
- Synthetic tiles: 20 to 50 years
- GRP fibreglass: 20 to 30 years
- Felt roofing: 10 to 20 years
Proper installation and regular maintenance can extend the life of any roof.
What happens if it rains during the job?
We monitor the weather closely and plan work during dry periods whenever possible. If it rains unexpectedly, we cover the roof with protective sheeting to keep your home dry.
Modern breathable underlay also provides temporary protection once installed, even before the tiles are laid.
Will the work create a lot of mess?
There will be dust, debris, and waste materials during the project, but we work hard to keep things tidy.
We use skips to remove waste and protect your garden with dust sheets. At the end of the job, we do a full site clean-up and sweep with magnetic rollers to pick up any stray nails.
How do I know my roofer is trustworthy?
Look for:
- Proof of insurance
- Written quotes with clear terms
- Membership of trade bodies or competent person schemes
- Local references and online reviews
- Clear communication and no pressure sales tactics
Roofing Newcastle is fully insured, independently reviewed, and has completed hundreds of local projects. We’re always happy to provide references or show examples of our work.
What’s the warranty on a new roof?
Warranties vary depending on the contractor and the materials. Most new roofs come with a workmanship guarantee and a separate manufacturer’s warranty for the tiles or covering.
Typical coverage includes:
- 10 to 15 years for workmanship
- 30 to 60 years for materials
At Roofing Newcastle, we provide written guarantees on all roof installations, including both workmanship and materials.
Can I install solar panels on a new roof?
Yes, and it’s a great time to do it. Installing solar panels during a roof replacement makes the process easier and cheaper, as scaffolding is already in place and fixings can be integrated into the new roof.
We regularly coordinate with solar installers to make sure the roof structure is ready and properly sealed.
Will a new roof add value to my home?
Yes. A new roof can increase your property value and improve its energy efficiency. It also reassures buyers that they won’t have to deal with leaks or repairs for many years.
Homes with new roofs often sell faster and closer to asking price.
How can I maintain my new roof?
Here are a few tips to keep your roof in good shape:
- Have it inspected every few years
- Keep gutters clear of leaves and debris
- Trim overhanging branches
- Check for missing or slipped tiles after storms
- Act quickly if you notice damp spots or leaks
Most roof issues can be fixed cheaply if caught early. We offer maintenance advice and roof check-ups at Roofing Newcastle for past clients.
