    Commercial Roofing FAQs

    Honest answers to the most common questions UK building owners, facilities managers, and surveyors ask us about commercial liquid waterproofing, cut edge corrosion, gutter lining, and asbestos encapsulation.

    General

    About Dynamic Commercial Roofing and the services we deliver.

    What does Dynamic Commercial Roofing specialise in?

    We provide contractor-led commercial roof condition surveys and specification-led liquid waterproofing, cut edge corrosion treatment, gutter lining and suitable asbestos cement roof encapsulation. We do not undertake domestic roofing work.

    Where are you based and where do you work?

    Our head office is at Rother Way, Hellaby, Rotherham S66 8QN. From our South Yorkshire HQ we serve commercial roofing clients across the UK.

    Do you only work on flat roofs?

    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.

    Are you accredited and insured?

    Yes. We maintain current £10m insurance cover. Our operatives are directly employed, relevant operatives are CITB-trained, and we hold current manufacturer approvals and accredited-installer status. Qualifying systems can carry a 20-year guarantee subject to the written terms supplied for the project.

    Costs & Pricing

    How project-specific pricing, surveys and quotations work.

    How much does commercial liquid waterproofing cost?

    Pricing depends on roof area, substrate condition, preparation, access and the system specified. We provide a free site survey followed by a fixed-price written quotation for the agreed scope.

    How much does cut edge corrosion treatment cost?

    Pricing depends on corrosion severity, the length and location of affected edges, access requirements and the system specified. A free condition survey is followed by a fixed-price written quotation.

    How much does commercial gutter lining cost?

    Pricing depends on gutter profile, substrate condition, repairs, outlets and the access method. We inspect the gutter free of charge and provide a fixed-price written quotation for the specified work.

    How much does asbestos roof encapsulation cost?

    Pricing depends on the roof condition, existing asbestos survey, access, preparation and the encapsulation system specified. Following a free site survey, we provide a fixed-price written quotation where encapsulation is suitable.

    Is the site survey really free?

    Yes. Our initial contractor-led roof condition survey supports repair or refurbishment advice and a fixed-price written quotation, free of charge with no obligation. Safe access, coverage and exclusions are agreed before the visit. It is not an independent structural or asbestos survey; specialist access and diagnostic testing are not automatically included.

    Are your quotations fixed price or estimates?

    We provide fixed-price quotations in writing following the free site survey. The proposal identifies the agreed specification, system, area and price; any changes to the agreed scope are addressed in writing.

    Process & Timescales

    How projects are scoped, scheduled, and delivered.

    How long does a typical project take?

    Project duration depends on the specified product, weather, access, roof condition and scope. The written programme and product system data control sequencing, cure periods and completion requirements for the project.

    Will my building need to close during the work?

    The need for closures, phased work or localised restrictions depends on the system, site access, building use and risk controls. The survey and written programme identify the appropriate arrangements for the project.

    What happens during the free site survey?

    A surveyor visits the site, takes measurements, photographs the roof condition, identifies visible substrate or structural concerns, and discusses your requirements. We then prepare a written recommendation and fixed-price quotation.

    Do you work weekends and out of hours?

    Out-of-hours or weekend work can be considered for retail, healthcare, education or distribution sites where the agreed programme and site constraints require it. Any programme and associated costs are set out in the fixed-price written quotation.

    How quickly can you respond to an emergency leak?

    Contact us by phone to discuss an active commercial roof leak. Availability and attendance depend on location, site access, weather and current workload, so no fixed response or attendance time is promised.

    Guarantees & Compliance

    Workmanship guarantees, certifications, and standards.

    How long are your guarantees?

    Qualifying systems can carry a 20-year guarantee. The scope, conditions and responsible parties are set out in the written guarantee terms supplied for the project.

    What standards do your systems meet?

    Applicable product data, certifications and performance information depend on the specified system. Relevant documentation can be reviewed as part of the project specification.

    What pre-qualification accreditations do you hold?

    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.

    Health, Safety & Asbestos

    Working safely on commercial and industrial roofs.

    Do you require an asbestos survey before starting work?

    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.

    What CDM duties do you take on?

    CDM roles, method statements, risk assessments, site logistics and handover documentation are agreed for the specific project and recorded in the written project arrangements.

    How do your operatives access the roof safely?

    Roof access is planned through a project-specific work-at-height assessment. The selected access method may include MEWPs, scaffold edge protection, fall-arrest systems or other suitable controls, as set out in the written plan.

    Are your operatives directly employed?

    Our roofing operatives are directly employed and installation is kept in-house. Relevant operatives are CITB-trained; role-specific training and site requirements are confirmed in the project documentation.

    What is your safety record?

    Project-specific health and safety documentation, training records and current insurance evidence can be provided during pre-qualification or tender review.
