Expert Guidance
When Does a Roof Need Replacing, Not Just Repairing?
In many cases, a roof repair is all that’s needed. However, there are situations where replacing the roof is the safer and more cost-effective option long term.
Our team will always assess whether a repair is suitable before recommending a full replacement. If a repair is the better option, we’ll tell you.
A roof replacement may be recommended if you’re experiencing any of the following:
- Widespread damaged or missing tiles/slates
- Deteriorated roofing felt or battens
- Ongoing leaks despite previous repairs
- Roof nearing the end of its expected lifespan
- Structural concerns or sagging areas
- Major refurbishment or property upgrade plans

“I needed a small flat roof replacing. I’d already used this company a few years ago when they did a full roof replacement. Very friendly company, always kept in the loop of what work they would do and a timeline of when it would be done. Job was done to a high standard and I would fully recommend them.”
Charlotte
“A. Armstrong were fantastic. Knowing that we had to have a new roof, winter wasn’t the best time to start. The team were excellent and just worked hard to complete the job. From the moment the materials arrived, the break in the weather meant they could commence. We are really happy with all the work as it is such a relief to have peace of mind. Thank you to all at A. Armstrong for keeping us informed at all times.”
Rosemary
“New roof put on our garage, very professional company from start to finish and left everything tidy afterwards. Very reasonably priced compared to some other quotes. Highly recommended and would definitely use again if required.”

Frequently asked questions
We understand that replacing a roof is a big decision, and it’s normal to have questions before getting started.
Below you’ll find answers to some of the most common questions we’re asked about domestic and commercial roof replacements, timescales, guarantees and what to expect from the process.
How long does a roof replacement take?
Most roof replacements are completed within 3–5 days, depending on the size of the property, roof design and weather conditions. We’ll always provide a clear timescale before work begins.
Can a roof be replaced in winter?
Yes. Roof replacements can be carried out year-round. We monitor weather conditions closely and schedule work during suitable windows to ensure everything is completed safely and correctly.
Will scaffolding be required?
In most cases, scaffolding is required to allow safe access and protect your property. If scaffolding is needed, this will be clearly included in your quotation.
How do I know if I need a replacement or just a repair?
We’ll always assess whether a repair is suitable before recommending a full replacement. If a repair is the better option, we’ll advise you honestly. A replacement is usually recommended when damage is widespread or the roof has reached the end of its lifespan.
Do you remove all old roofing materials?
Yes. Existing tiles or slates are removed as part of the job, and all waste is taken away, leaving your property clean and tidy once work is complete.

All roof replacement work is covered by a 10-year workmanship guarantee. As NFRC registered contractors, insurance-backed guarantees may also be available for additional peace of mind.
