Okehampton Asbestos Shed Roof Removal and Replacement
Across Okehampton and the surrounding Devon area, a number of older garden buildings, garages and workshops retain asbestos cement roof sheets. Although asbestos-containing products are no longer installed, older corrugated cement sheets remain present on existing roofs throughout Devon.
Asbestos cement is generally lower risk than softer asbestos products when the sheets remain intact and are left undisturbed. Problems arise when the material deteriorates, suffers storm damage or is disturbed using unsuitable tools and methods.
We help customers in Okehampton request quotations for removing suspected or confirmed asbestos cement sheets and installing modern replacement roofing. Complete one online enquiry and you may receive contact from up to four relevant contractors serving Okehampton and nearby areas of Devon.
About Corrugated Asbestos Cement Sheets
Asbestos cement was manufactured as a rigid material for roofing sheets, wall cladding, pipes and other building products. Roof sheets are commonly grey or off-white, although age, moss and weathering can change their appearance.
Modern non-asbestos fibre-cement products may look almost identical to older asbestos cement roofing. Until the material has been identified, it is sensible to treat a suspect roof as though it may contain asbestos.
Identifying Suspect Corrugated Roof Sheets
Older grey corrugated sheets are often associated with asbestos cement, although similar non-asbestos materials also exist.
Possible indicators include:
- Rigid grey or off-white corrugated sheets.
- Panels secured with bolts or hook fixings.
- Cement verge or closure components.
- An outbuilding constructed or re-roofed several decades ago.
- Moss growth across an old grey surface.
A suitable surveyor or trained person can arrange controlled sampling and laboratory analysis where confirmation is needed.
Does an Asbestos Shed Roof Need Removing?
Sound asbestos material that is unlikely to be disturbed can sometimes be managed in place. Homeowners should also consider whether the outbuilding is being renovated, converted or demolished.
Removal may be appropriate when:
- Several panels have visible damage.
- Several joints are no longer watertight.
- Storm damage has fractured or displaced the panels.
- The roof frame needs major repair.
- A modern roof system is required for a change of use.
- The outbuilding is due to be demolished.
- Ongoing monitoring and minor repair are no longer practical.
Warning Signs on an Older Outbuilding Roof
Homeowners should not climb onto a suspected asbestos cement roof to inspect it.
Possible signs of deterioration include:
- Damage around fixings, corners or sheet edges.
- Missing corners and broken edges.
- Bolts and washers no longer securing the sheets.
- Damp patches beneath the roof after rainfall.
- Heavy surface weathering.
- Vegetation collecting around sheet overlaps.
- An uneven roof line suggesting structural damage.
- Damage after high winds or storms.
- Pieces of cement roofing beneath the eaves.
Actions That Can Damage Suspected Asbestos Roofing
Suspected asbestos cement should not be treated like an ordinary modern roofing sheet.
Unsafe actions include:
- Attaching battens, brackets or solar equipment through the panels.
- Cutting sheets with a saw or abrasive disc.
- Snapping panels to make them easier to carry.
- Creating asbestos cement dust with abrasive equipment.
- Pressure washing the roof.
- Brushing damaged material with a stiff broom.
- Assuming the panels can safely support a person's weight.
- Putting asbestos waste into household bins or ordinary skips.
- Accepting a quote that does not explain the disposal route.

Asbestos Surveying and Sampling
Testing can distinguish older asbestos cement from similar modern fibre-cement sheets. A laboratory result can help contractors plan the work and prepare an appropriate quotation.
Risk Assessment and Work Planning
The condition of the sheets, roof access and likelihood of breakage should be considered during planning.
Preparation can involve:
- Confirming the roofing material and its condition.
- Assessing the correct work category.
- Avoiding direct walking on roof sheets.
- Restricting access to the immediate work area.
- Providing appropriate work clothing and respiratory protection where required.
- Avoiding dropping panels from height.
- Arranging waste packaging, transport and disposal.
Taking Roof Panels Down Whole
Roof fixings should be dealt with using an appropriate method that avoids unnecessary cutting, grinding or drilling.
- Using controlled wetting where required by the work method.
- Avoiding methods that damage the cement panels.
- Preventing the panels from bending, slipping or snapping.
- Lowering sheets carefully to ground level.
- Using suitable cleaning methods around the work area.
Preparing Asbestos Sheets for Transport
Removed sheets and fragments need packaging that prevents asbestos waste escaping during handling or transport.
- Using sealed plastic sheeting around intact panels.
- Keeping loose material securely contained.
- Sealing packages with strong tape.
- Clearly identifying the packages as asbestos waste.
- Preventing wrapping from becoming damaged in the vehicle.
Asbestos Waste Transport and Disposal
A contractor transporting asbestos waste should use the appropriate registered carrier and authorised disposal route.
Waste arrangements should cover:
- Who will transport the asbestos waste.
- How the waste carrier details can be checked.
- Whether the destination accepts asbestos cement waste.
- What paperwork will be supplied.
- The cost of packaging, transport and tipping.
Preparing an Outbuilding for Demolition
Some homeowners require removal only because the shed or garage is due to be demolished.
Different materials may require separate waste arrangements.
Complete Asbestos Shed Roof Replacement
Many projects combine asbestos cement sheet removal with installation of a modern replacement roof.
Removal and replacement work can involve:
- Packaging and disposal of asbestos waste.
- Inspection of purlins, rafters and wall plates.
- Strengthening weak roof supports.
- Adapting the roof for more effective drainage.
- Installation of new roof sheets or membranes.
- Improving rainwater drainage.
Choosing a New Outbuilding Roof
Corrugated Metal Roofing
Lightweight metal roofing can provide a robust covering where the existing frame is suitable. Existing purlins may need adjustment to suit the new sheet profile.
Corrugated Bitumen Sheets
These lightweight panels can be installed on suitable battens or purlins. Ridge and verge components should be included in the complete specification.
Modern Fibre-Cement Sheets
This option may suit homeowners who want to retain a corrugated cement-style finish. Safe access precautions may still be required because sheeted roofs can be fragile.
EPDM Rubber Roofing
Rubber roofing is commonly used on flat and low-pitched sheds, workshops and garden buildings. The roof fall should direct water towards a gutter or drainage edge.
Mineral Roofing Felt
Felt can provide a lower-cost replacement for a simple shed roof. A higher-grade felt may offer improved durability compared with basic shed products.
GRP Fibreglass Roofing
Fibreglass creates a hard and largely seamless waterproof finish. Local repairs may be possible if accidental damage occurs later.
Plastic and Polycarbonate Roof Sheets
Translucent panels can suit potting sheds, workshops and lean-to structures. The roof pitch should meet the requirements of the chosen panel system.
Repairing the Existing Roof Frame
Leaks around old fixings and overlaps can damage timber or metal supports beneath the panels.
- Installing new treated timber for the replacement sheets.
- Repairing rafters and joists.
- Repairing the point where the roof meets the walls.
- Assessing whether rusted components remain structurally sound.
- Installing a new timber roof deck.
- Correcting areas where water collects.
- Providing fixing points for trims and guttering.
Outbuildings with Asbestos Cement Roofs
Local contractors may work on various domestic, agricultural and light commercial outbuildings.
- Small domestic outbuildings.
- Detached garages.
- Hobby rooms and work sheds.
- Detached property outbuildings.
- Farm sheds and small agricultural buildings.
- Covered side passages.
- Business outbuildings.
- Old boiler rooms and plant enclosures.
- Communal garage roofs.

Frequently Asked Questions
How do I know if my shed roof contains asbestos in Okehampton?
Older grey or off-white corrugated cement sheets may contain asbestos, particularly where the roof was installed several decades ago. Sampling should be arranged using suitable controls rather than by breaking off a piece yourself.
Is an asbestos shed roof dangerous?
A sound roof that is left undisturbed does not normally release large amounts of fibre. The risk increases when sheets are cut, drilled, broken, heavily weathered or cleaned aggressively.
Does every asbestos cement roof need a licensed contractor?
Some work may be non-licensed where the sheets can be removed carefully without substantial breakage. The contractor should explain the classification and the controls required.
Can an intact asbestos shed roof be left in place?
An intact asbestos cement roof does not always need immediate removal. The roof should be checked after severe weather.
Can I remove an asbestos shed roof myself?
The fragile roof also creates a serious risk of falling through the sheets. Using a competent contractor is usually the safer and more practical option.
Can asbestos roof sheets be cut or broken?
Cutting, drilling, grinding or deliberately breaking panels can increase fibre release. Power tools should not be used simply for speed or convenience where they damage the material.
Can an asbestos shed roof be pressure washed?
High-pressure washing can damage the cement surface and spread contaminated debris. Leaving sound material undisturbed may be safer than attempting cosmetic improvement.
How is asbestos roof waste disposed of?
A contractor carrying the waste should use the appropriate registered carrier arrangements and authorised receiving facility. The applicable hazardous waste documentation should accompany the movement.
What can replace an asbestos shed roof in Okehampton?
The best replacement depends on the existing frame, roof pitch, budget and use of the building. A local contractor can compare suitable options for the building.
Can the old roof frame be reused?
Existing purlins, rafters and wall plates may be retained if they are structurally sound and suitable for the new material. Additional battens or deck boards may be needed for a different roofing system.
How long does asbestos shed roof removal take in Okehampton?
Broken panels and difficult working areas may require extra time and controls. Installing a replacement roof may add another day or longer.
Is asbestos shed roof removal covered by home insurance?
Sudden insured damage may be treated differently from planned replacement of an ageing roof. Urgent safety measures should not be delayed while waiting for an insurance decision.
How much does asbestos shed roof removal cost in Okehampton?
The cost depends on the roof size, sheet condition, access, work category and disposal requirements. Replacement roofing should be specified with its trims, fixings and drainage details.
