Question 1

What does Dynamic Commercial Roofing specialise in?

Accepted Answer

We are UK commercial roofing specialists focused exclusively on liquid waterproofing, cut edge corrosion treatment, gutter lining, and asbestos cement roof encapsulation. We do not work on domestic roofing, every project we deliver is on a commercial, industrial, public sector, or institutional building.

Question 2

Where are you based and where do you work?

Accepted Answer

Our head office is at Unit 2 Rother Way, Hellaby, Rotherham S66 8QN. From our South Yorkshire HQ we deliver projects across the UK, with active project teams regularly working in Yorkshire, the East and West Midlands, the North West, the North East, London, and the South East.

Question 3

Do you only work on flat roofs?

Accepted Answer

No. While liquid waterproofing is most associated with flat and low-pitched roofs, we work on the full range of commercial roof types including profiled metal industrial roofs, asbestos cement sheet roofs, valley and box gutters, parapet gutters, and complex roofs with multiple penetrations and details.

Question 4

Are you accredited and insured?

Accepted Answer

Yes. We are fully insured for £10m public liability and £10m employer's liability, and every system we install is fitted by directly employed, CITB-trained operatives holding manufacturer-approved installer status. All qualifying works are covered by a 20-year workmanship guarantee.

Question 5

How much does commercial liquid waterproofing cost?

Accepted Answer

Commercial liquid waterproofing typically costs £20–£40 per square metre fully installed including surface preparation, primer, reinforced membrane, and UV-stable topcoat. A 500m² industrial roof equates to approximately £10,000–£20,000, typically less than half the cost of strip-and-replace re-roofing. All quotes are fixed in writing following a free site survey.

Question 6

How much does cut edge corrosion treatment cost?

Accepted Answer

Cut edge corrosion treatment typically costs £8–£18 per square metre depending on corrosion severity, access requirements, and the system specified. This compares with £40–£70 per square metre for full metal re-sheeting, making treatment 60–80% cheaper for the same long-term weathertight outcome.

Question 7

How much does commercial gutter lining cost?

Accepted Answer

Commercial gutter lining typically costs £60–£150 per linear metre depending on gutter profile, substrate condition, and access method. For a 200m perimeter industrial unit this equates to £12,000–£30,000, typically half to one-third of full gutter replacement cost for the same length.

Question 8

How much does asbestos roof encapsulation cost?

Accepted Answer

Asbestos cement roof encapsulation typically costs £15–£30 per square metre. For a 2,000m² industrial roof this equates to £30,000–£60,000, versus £100,000–£160,000 for licensed removal and re-roofing. Encapsulation is HSE-compliant for non-friable asbestos cement sheets in serviceable condition.

Question 9

Is the site survey really free?

Accepted Answer

Yes. Every initial site survey, condition assessment, and written fixed-price quotation is provided free of charge with no obligation. We will not charge for surveys, drone inspections, photographic reports, or initial specifications.

Question 10

Are your quotations fixed price or estimates?

Accepted Answer

All our quotations are fixed price in writing. Following the free site survey we issue a detailed proposal listing the exact specification, system, area, and price, with no hidden extras for substrate repairs, primer, mobilisation, or detailing. The price you accept is the price you pay.

Question 11

How long does a typical project take?

Accepted Answer

Most standard commercial roofing projects complete in two to ten working days. Liquid waterproofing on a 500m² roof typically takes two to five days, cut edge corrosion treatment on a 3,000m² unit takes five to ten days, and gutter lining on a 200m perimeter takes two to five days. Larger projects are sectioned and delivered phased.

Question 12

Will my building need to close during the work?

Accepted Answer

No. All our refurbishment systems are specifically chosen because they can be installed while the building remains fully occupied and operational. We work in phased sections, schedule noisy preparation around your working hours where required, and never require a complete site shutdown.

Question 13

What happens during the free site survey?

Accepted Answer

A senior surveyor visits the site, takes detailed measurements, photographs the roof condition, identifies any substrate or structural issues, and discusses your specific requirements and constraints. You receive a written condition report, system recommendation, and fixed-price quotation typically within five working days.

Question 14

Do you work weekends and out of hours?

Accepted Answer

Yes, where required for retail, healthcare, education, or distribution sites. We routinely deliver projects out of hours, overnight, or across weekends to avoid disrupting trading, clinical activity, term-time, or 24/7 logistics operations. There is no premium for standard out-of-hours work that is planned at the quotation stage.

Question 15

How quickly can you respond to an emergency leak?

Accepted Answer

We respond to commercial emergency leak callouts within 24 hours nationally and within four hours across South Yorkshire and the surrounding region. Emergency response includes leak source investigation, immediate temporary watertight repair, and a follow-up specification for permanent remediation.

Question 16

How long are your guarantees?

Accepted Answer

All our liquid waterproofing, cut edge corrosion, gutter lining, and asbestos encapsulation installations carry a 20-year workmanship guarantee as standard. Full guarantee documentation is issued directly to you on completion of the project.

Question 17

What standards do your systems meet?

Accepted Answer

All systems we install are independently certified to recognised UK and European technical standards, with fire performance to BS EN 13501 and slip resistance and durability tested to relevant British and European standards. Full certification documentation is provided with every project.

Question 18

What pre-qualification accreditations do you hold?

Accepted Answer

We can meet the standard contractor pre-qualification requirements typically asked of commercial roofing specialists for framework and tender purposes. Current accreditation documentation is supplied on request as part of any tender submission.

Question 19

Do you require an asbestos survey before starting work?

Accepted Answer

Yes. A current asbestos management or refurbishment survey must be in place before any work begins on any building constructed before 2000. If you do not hold a current survey, we can recommend accredited asbestos consultants. We will not commence work without confirmed survey documentation.

Question 20

What CDM duties do you take on?

Accepted Answer

On every project we act as Principal Contractor under the Construction (Design and Management) Regulations 2015 unless otherwise agreed. We produce written method statements and risk assessments, manage site logistics, and deliver the Health and Safety File on completion.

Question 21

How do your operatives access the roof safely?

Accepted Answer

All roof access uses a documented work-at-height plan compliant with the Work at Height Regulations 2005. We deploy a combination of mobile elevating work platforms (MEWPs), scaffold edge protection, mobile fall arrest systems, and IRATA-trained rope access depending on the safest method for each project.

Question 22

Are your operatives directly employed?

Accepted Answer

All our roofing operatives are directly employed PAYE staff, installation is kept fully in-house. Every operative holds a CSCS card, IPAF (where MEWP-trained), Working at Height training, and asbestos awareness or non-licensed asbestos work training where applicable.

Question 23

What is your safety record?

Accepted Answer

Zero RIDDOR-reportable incidents to date across our installation history. Our HSE accident frequency rate (AFR) is well below industry benchmarks and we publish our safety performance annually as part of our framework and tender submissions.

Question 24

Do you work nationally or only in Yorkshire?

Accepted Answer

We work nationally. While our HQ is in Rotherham, South Yorkshire, we deliver commercial roofing projects across the entire UK including London, the Midlands, the North West, the North East, the South West, Scotland, and Wales. We have active projects across at least eight regions in any given month.

Question 25

Which regions do you have dedicated location pages for?

Accepted Answer

We publish detailed location information for South Yorkshire (Sheffield, Rotherham, Barnsley, Doncaster), West Yorkshire (Leeds), Greater Manchester, the West Midlands (Birmingham), the East Midlands (Nottingham), and London. Other regions are covered nationally without a dedicated location page.

Question 26

Do you have a minimum project size?

Accepted Answer

Outside of South Yorkshire our typical minimum project size is £10,000 to make travel and mobilisation cost-effective. Within South Yorkshire we have no minimum project size, we routinely deliver smaller localised gutter and waterproofing works from our Hellaby HQ.

Question 27

Do you work for facilities management companies and main contractors?

Accepted Answer

Yes. We are a regular subcontractor to national FM providers, building consultancies, surveying practices, and main contractors. We are framework-ready and can supply current pre-qualification documentation as required for tender submissions.
