“If you’ve had enough of a poorly built home extension roof, you are in the right place!”
Roof extension issues often get fixed with a single repair costing £2,000-£4,000. Hopefully your issue gets fixed and you have no ongoing problems.
Over the last 20 years we’ve come across hundreds of home extension roofs that require constant repairs. Spending £2,000-£4,000 every couple of years can really start to add up.
Why is there a problem with my home extension roof?
Home extensions are often built by smaller, less established builders who don’t have the knowledge and skill levels to ensure that the roofs that they work on will last for decades. In comparison, a main house roof will be constructed by experienced homebuilders and will usually have little or no problems over the lifetime of the house.
Many materials, many problems!
Home extension roofs are constructed with a wide variety of materials. Slate, Tile, PVC Felt, Ash Felt, Fibreglass, Aluminium Panels, Zinc Panels, and Industrial Steel Panels are all commonly used. It is very challenging for less knowledgeable and experienced builders to understand the correct design and workmanship required for all of these materials.
Are you experiencing any of these 5 extension roof problems?
1. Water leaking through windows and along internal ceilings and walls
2. Damp stains on ceiling and discoloured plasterwork caused by condensation
3. Blocked guttering and overflowing guttering
4. Pools of water on your extension roof
5. Visible damage on metal, felt and slate and tiled roofs
If your roof extension has numerous problems, a Zinc Roof might be the answer
1. Why smart homeowners use Zinc for their home extension roofs
2. Eliminate unplanned expenditure on your property
3. A zinc roof adds value to your property
4. A new zinc roof is an architectural feature
5. Your new zinc roof will be in safe hands

Boyle Copper & Zinc Craft Ltd offer a 10-year Workmanship Warranty as standard. We are so confident of our work, that our Workmanship Warranty will cover both the design of your new Zinc Roof and the roofing installation works.

This insurance will ensure any required repairs to your roof will be covered even if Boyle Copper & Zinc Craft Ltd go out of business.
“The latest project was a renovation of an office block (we were adding 2 floors) and Boyle Copper & Zinc Craft Ltd carried out the zinc works on the roof. This was the 3rd project we had worked with Boyle Copper on.
We first heard of them when we were working on a past project and they were specified by an architect. We were impressed with their work so kept them on. We had developed a good relationship with them over the previous projects and wanted to work with them again. Their prices were competitive, we worked well with the guys on site and the finished result was great. We’ve used others in the past for smaller jobs but not for bigger jobs like these – zinc has become much more popular than lead over the past few years.
Their communication was really good, they were quick to come back on emails and Alan was very quick to arrange site visits so he could understand the works. The works were planned very well. I would definitely recommend them. They worked well and were very competitive.“
Ryan Davis, Roots Contractor Ltd (www.rootscontractors.co.uk), Builder
“This was the first time we had used anyone for cladding. As a site manager I inherited the decision to go with Boyle Copper. The subcontractors had used them before and were happy with them, there was no risk and the quality was high. Communication with Alan and his team was excellent.
Alan is a very busy man, but he always came back to me via phone, email or text. I would recommend Boyle Copper. They all went out of their way to help and we will keep on using them for future jobs.”
Andries Van Rensburg, Heydon & Carr Construction (www.heydonandcarr.co.uk), Site Manager
“Boyle Copper carried out the zinc wall cladding for us on a residential rear extension in North London. We heard about Boyle Copper through a Google search. Boyle Copper was one of two that we approached. We chose Boyle Copper because their price was in line with the other supplier, so we knew the job was priced correctly. Also because of the speed with which Alan reacted to our enquiry. As soon as we’d emailed, he was on the phone to discuss the project. He also followed up to chase us up which was good. Others were less forthcoming, especially as it was a small job.
Alan offered a CPD session for our team which was really good. Alan also advised us on another project with his expertise which was great.
I appreciated that they chased up the job even though it was small. Generally great communication with Alan and the guys on site. I would recommend Boyle Copper and would use them again. They were quick to reply and did the work quickly and accurately. The guys on site were also very skilled. I would use them as my preferred contractor.”
Stephen Mackie, Sean and Stephen Architects (www.seanandstephen.com), Architect
“Boyle Copper helped us on the re-roofing of our converted factory in East London. This involved removing the existing aluminium sheeting and installing a new cool roof solution with standing seam VMZinc. The works were further complicated by the fact that a large array of solar panels had to be removed, stored and reassembled. Paul Cousins, Business Development Manager (SIG Roofing Advisory List) came to look at the site and recommended Boyle Copper & Zinc Craft Ltd.
We chose Boyle Copper because they demonstrated that they were knowledgeable, helpful and interested in the details, which gave us confidence. Also the price was competitive compared to our other quotes. The communication was really good. Alan always got back to us in a timely manner and the guys on site were brilliant – they were always on time and very considerate.
I would certainly recommend Boyle Copper & Zinc Craft Ltd. Technically they were excellent, they were also considerate, flexible and good value for money.”
Brian Ford, Building Owner, East London
“Boyle Copper helped on two projects so far. One project was a pair of rooftop extensions on two late twentieth century houses and the other was a ground floor addition to a Georgian house in Fitzrovia.
For the first project Boyle Copper came by recommendation from the contractor. On second project we asked that they be included, based on the quality of their previous work for us. Alan has been very helpful and offers his technical advice and expertise on resolving details and interfaces.
We have already recommended Boyle Copper to others.“
Graham West, Director, West Architecture
“Our architect brought Boyle Copper on board. He recommended them as he had used them on other projects and the price matched with expectations. Communication was very good with Alan and the team. It was perfect for the job.
I would recommend Boyle Copper – a) because their price was what we had budgeted and b) the product and application was to a high standard.”
Barry Doherty, Argyle House Property Developers, Property Developer
“Boyle’s were by far the most reliable contractors for this type of work that we have used. Communication was first class with Alan always on hand to help the architects with regs, detailing and design issues.”
Tony Bracaglia, Famella Construction (www.famella.co.uk), Builder
Our quote will be in the range of £500 – £700 per square meter of roofing depending on the complexity of your extension roof. A typical roof extension of 30 square meters will be around £16,000. This will include the full renovation of the roof (removal of the old roof and insulation, addition of new insulation and the new zinc roof). The price excludes new or additional windows and skylights.
Possibly, on rare occasions. For example, if we open the roof and find a damaged joist that needs to be replaced; plumbing that needs to be diverted; electrical wiring that was not visible at the time of quotation. Basically, things that cannot be foreseen at the time of quotation. If this occurs, we will clearly show you the additional works that need to be done and we will do them at cost.
Generally, we would require a 50% deposit followed by 50% payment of balance when half the works are complete. We can also offer an incremental payments option depending on your personal credit rating.
4. How can I check your Coppersmith qualification and membership with the relevant trade federations to confirm that you are a reputable contractor?
Alan Boyle, the director of the company, is a qualified Coppersmith with over 25 years of experience who trained in Munich, Bavaria. Boyle Copper and Zinc Craft Ltd are registered with FTMRC and VM Zinc. You can contact them directly to verify our membership. Our FTMRC membership requires our work to be checked on an annual basis by FTMRC.
Upon request, we can send you photos of similar jobs.
Generally, yes. We work directly with many architects, so we will be happy to speak with your architect. If you don’t have an architect, we will be able to design your Zinc Roof for you ourselves.
Generally, there is no requirement for planning permission. You can inform your neighbours that you are having works done once we have confirmed your installation date, so they won’t become concerned if they see strangers arriving at your property.
Yes, we do this regularly and work with the major brands. We can install Velux and similar. For an additional charge, we will be able to do this work at the same time as your Zinc Roof installation.
Yes, we do this regularly and work with the major brands. We can install Velux and similar. For an additional charge, we will be able to do this work at the same time as your Zinc Roof installation. You can make good any internal plasterwork yourselves, or we will be able to find you a local tradesman to complete the internal works for you.
Yes. Our price per square meter generally includes all associated gutters, downpipes, soffits and fascias on the roof extension supplied in Zinc. Subject to an additional cost, you can also opt for matching Zinc equipment on the main house roof.
Normally we recommend using the natural grey Zinc (known as Zinc Quartz) as it blends in well with all other building materials. We can offer other colours which would be more expensive.
12. I have noticed "waviness" in the zinc roofing panels in your photos. Will I also get this "waviness" effect in my new Zinc Roof?
This waviness is called the “oil canning effect” and is a natural characteristic of the Zinc material. This will give your new Zinc Roof a more natural rather than a manufactured look.
It is extremely rare that this will happen. If it does occur, please contact us. Providing that the installation is still within our 10-year Workmanship Warranty period, we will come out to investigate and rectify the situation.
On average it will take 1 week. We first remove the old roofing followed by installation of the new timber decking which is then followed by installation of the Zinc Roof.
