Partners

Some of their well-known partners include Rockwool, Saint-Gobain, Wienerberger, Isover, Dow and Recticel.
Rockwool
Rockwool is an insulating material made from rocks by a company called Rockwool and they are partners of SIG Plc.
The product is used in construction and machinery to provide thermal insulation and soundproofing. Rockwool is also used as a gardening substrate to help plants grow.
Rockwool is made from basalt, a type of rock that is melted and spun into fibres. The resulting product is then formed into slabs or rolls. Rockwool has a high heat capacity, meaning it can absorb and store heat energy. This makes it an ideal material for insulation, as it can keep homes and buildings warm in winter and cool in summer. Rockwool is also fire resistant, making it an ideal choice for use in fire-prone areas.
In addition to its thermal properties, Rockwool also has excellent acoustic properties. It is often used as a soundproofing material in homes and buildings. Rockwool can also help to reduce noise pollution in urban areas.
Rockwool is an environmentally friendly material that is recyclable and does not release harmful chemicals into the atmosphere. It is also biodegradable, making it an ideal choice for use in gardening and horticulture.
Rockwool is available in a variety of densities, depending on its intended use. For insulation, lower density rockwool is typically used, while higher density rockwool is better suited for soundproofing applications.
Saint-Gobain
Saint-Gobain is a world leader in sustainable construction solutions and is committed to supporting SIG Plc in its efforts to create a more sustainable built environment. The two companies have jointly developed a range of innovative products and solutions that help to reduce the environmental impact of construction projects.
One example of this is the use of recycled glass in the manufacture of insulation materials. Recycled glass is an environmentally friendly resource that helps to reduce emissions and conserve energy.
Another example is the use of sustainable timber in construction projects. Sustainable timber is a renewable resource that helps to reduce the carbon footprint of a project.

Roofing Contractor Near Me - Our Roofing Capabilities
What’s Covered When We Quote Using SIG Plc Materials
- Pitched roof tiling and underlay systems sourced through SIG’s roofing range
- Flat roof membranes and dry ridge or verge kits
- Insulation boards from SIG partner brands such as Rockwool, Isover and Recticel, for loft, roof and cavity applications
- Rainwater goods, fascias and soffits
- Cladding and render systems for roofline and elevation work tied to a roofing project
- Material sourcing, delivery coordination and fitting carried out by our own roofing team
Not Included / Costed Separately
- Fitting or installation carried out by SIG Plc itself — SIG manufactures and distributes; our own roofers do the on-site work
- Solar PV, curtain walling and structural glazing systems from SIG’s wider catalogue, which sit outside a standard roof job and are quoted separately
- Specialist timber, civil engineering products and scaffolding or access equipment supply, which aren’t part of a typical residential roof repair or replacement
- Building control applications and planning permission, where these are needed on larger projects
How A SIG-Specified Roofing Job Runs From Call To Completion
- Initial call or enquiry: Tell us about the roof problem or project and, where useful, arrange a free drone roof survey so we can see the roof before anyone climbs a ladder.
- Site visit and specification: We look at the existing roof, discuss budget and finish, and match the job to suitable materials, including SIG-supplied tiles, membranes and insulation where they fit the brief.
- Quote and material sourcing: You get a written quote covering materials and labour, and we order stock through SIG Plc and other suppliers ahead of the start date.
- Installation: Our roofers carry out the tear-off, underlay, insulation, tiling or membrane and roofline work, using IPAF and PASMA-certified access equipment on taller sections or awkward pitches.
- Completion and sign-off: We clear the site, check the finished roof with you, and hand over any material guarantee paperwork that applies to the products fitted.

What A SIG Plc-Specified Roof Typically Costs
SIG Plc’s own range runs from standard, budget-friendly felt and insulation through to higher-specification boards from partner brands like Isover and Recticel, so the material choice alone can move the price of a job. On top of that, cost depends on roof size and pitch, how much of the existing covering needs stripping off, whether fascias, soffits or rainwater goods are being replaced alongside the roof, and what access equipment the job needs. A phone estimate can only ever be a starting point — a full, fixed quote needs a site visit, which is why we’d rather come and look at the roof, or arrange a drone survey first, before giving you a number to work with.
SIG Plc Material Types And Where They Fit On A Derby Roof
| Material type | Typical use on a Derby roof | Related SIG partner brand | Where it fits in a job |
|---|---|---|---|
| Insulation boards | Loft, roof and cavity insulation upgrades | Rockwool, Isover, Recticel | Added during a re-roof or as a standalone upgrade |
| Roofing tiles, felt and membranes | Pitched roof installation, repair and re-covering; flat roof replacement | SIG roofing range | Core material for new roofs and full re-covers |
| Rainwater goods, fascias and soffits | Roofline replacement alongside roofing work | SIG exteriors range | Usually quoted together with a re-roof to protect the new work |
| Render and cladding systems | Elevation and roofline detailing | SIG exteriors range | Added where roofline meets wall finish |
Sourcing The Right Materials, On Time, With The Paperwork To Match
Specifying a named material only pays off if the right product turns up on the right day — a job held up waiting on an insulation delivery, or fitted with the wrong roll of membrane, costs everyone time and money. Because we order through SIG Plc and their partner brands on a regular basis, we have a working feel for typical stock lead times across the ranges we use most, from Rockwool and Isover insulation through to standard felt and tile, and we build that into the quoted start date rather than guessing. The other side of using recognised manufacturer products is the paperwork that comes with them: a material guarantee only stands up if the correct product was fitted and the right certificate handed over afterwards, so we keep that documentation on file and pass it to you at completion rather than leaving you to chase a supplier for it later. A brand name on the bag or the box only means something if someone tracks which product went where and can prove it after the job’s done.


Where We Source And Fit SIG Plc Materials In And Around Derby
Derby and Derbyshire are our home patch for fitting SIG Plc-specified roofing systems, and the same material sourcing and fitting service reaches out to Nottingham, Nottinghamshire and Sheffield, then further afield to Leeds, Manchester, Doncaster, Wakefield, Rotherham, York, Hull, Newcastle, Sunderland, Durham, Glasgow and Liverpool. SIG Plc’s own distribution footprint already covers most of this ground, with a branch presence in Leeds and its head office in Sheffield, so getting SIG-supplied tiles, insulation or rainwater goods onto a job anywhere on that list rarely adds delay to the build schedule.
Frequently Asked Questions
Is Derby Roofers part of SIG Plc?
No. SIG Plc is a materials manufacturer and distributor with branches across the UK and Europe. We're an independent local roofing contractor based in Derby who buys and fits SIG-supplied materials, alongside products from other suppliers, on the jobs we carry out.
Do you only use SIG Plc products?
No. We specify whichever materials suit the job, budget and roof type, and SIG's range, together with partner brands such as Rockwool, Saint-Gobain, Isover, Dow and Recticel, is one of several sources we use.
Can I ask for a specific brand, like Rockwool or Isover insulation?
Yes. Tell us during the site visit or quote stage and we'll price the job with that material specified, where it's suitable for the roof.
Does using recognised manufacturer materials cost more?
Not necessarily. SIG's range covers a wide span of budgets, from standard felt and insulation to higher-specification boards, so the price depends more on which product tier and roof size you choose than on the fact that it's SIG-supplied.
Who actually fits the materials — you or SIG Plc?
We do. SIG Plc manufactures and distributes building materials; they don't send fitters to site. Our own roofers, who hold IPAF and PASMA certification for access equipment, carry out the installation.
Will I get guarantee paperwork for the materials fitted?
Yes. Where a SIG-supplied or partner-brand product carries a manufacturer guarantee, we hand over the relevant paperwork at completion so it's on file if you ever need it.
Does ordering through SIG Plc slow the job down?
Usually not. SIG has branches across most of the areas we cover, including Leeds, and a head office in Sheffield, so lead times on common products like felt, tile and insulation are generally short enough to fit around a normal quote-to-start schedule.
Which areas do you cover for this kind of roofing work?
Derby and Derbyshire first, plus Nottingham, Nottinghamshire, Sheffield, Hull, Leeds, Manchester, Doncaster, Wakefield, Rotherham, York, Glasgow, Newcastle, Sunderland, Durham and Liverpool.
How do I get a quote for a roof using SIG Plc materials?
Call us or arrange a free drone roof survey, and we'll follow up with a site visit and a written quote covering both materials and labour.
Get Your Derby Roof Quoted With Materials That Suit The Job
