Establish why replacement is proposed
Ask which parts have failed: the covering, deck, battens, membrane, flashing, structure or ventilation. Isolated defects may still be repairable. Wider decay or repeated failures can support renewal. A large alteration may also make renewal sensible. Ask the surveyor to write down the reason. Request photographs and a clear roof plan. Contractors may disagree about repair and replacement. Ask which observation causes that difference before comparing totals.
Define the complete roof area
The proposal should name every included roof section. Check each pitch, flat section, dormer and valley. Check chimney junctions, parapets and extensions too. Garages, porches and bay roofs are easy to overlook. Record which tiles or slates can be reused. Agree what happens if more are broken or missing. List gutters, fascias, soffits, roof windows and chimney work as included, optional or excluded.
Check structure before covering it again
Opening a roof may reveal decayed timber. It can also expose poor earlier alterations or an uneven base. Ask which checks happen before new materials are fixed. Name the person who can approve extra work. A set contingency is different from an open instruction to fix anything found. Agree how the contractor records new evidence, prices and delays. Identify any need for structural design or specialist advice before changing the load, form or support.
Coordinate insulation and ventilation
Roof replacement can bring building-regulation duties into the job. It can also change how moisture moves through the roof. Name the insulation layer, ventilation route and method used to control condensation. Ask whether the design is a cold roof or a warm roof. Check how air moves at eaves, ridges, abutments and openings. Do not add vents or insulation without checking the whole build-up. Keep product and compliance records at handover.
Compare coverings and fixing details
Product names are not enough. Name the material, profile, colour and fixing method. Add the underlay, battens, ridge and verge system. List flashings and matching accessories too. Check how wind exposure and roof pitch affect the choice. Confirm the maker’s fitting rules. Appearance may matter beside retained roofs or neighbouring homes. Use the exact address and proposal for any planning or heritage check.
Put access and weather protection in writing
Price scaffold, loading, skips and parking. Add shared access and protection for conservatories or neighbouring property. These items can change the total. The programme should show how the building stays dry while the roof is open. It should also cover severe weather. Ask who checks temporary protection. Agree how any damage inside the building will be handled. Safe access is part of the job.
Agree inspection and payment stages
Link payments to visible stages and agreed evidence. Useful points can include scaffold completion, strip-off findings, approved additional work, membrane and battens before covering, finished details and handover. Avoid paying for undefined future work. The contract should identify the roofing business, cancellation terms where applicable, insurance, dispute route and responsibility for subcontractors. Verify credentials with the issuing body rather than relying on a logo alone.
Collect a complete handover pack
Before final payment, review photographs, waste records where relevant, building-control documents, product information and written workmanship terms. Ask who handles any snagging and how to report a problem. Confirm that gutters and drainage paths are clear and that roof spaces are left safe. A verbal assurance cannot replace the accepted scope. Keep the final invoice and every approved variation with the property records.
Draw the roof before comparing replacement totals
Start with a simple plan of the main pitches, extensions, bays, dormers, valleys and lower roofs. Mark retained sections and shared boundaries. Ask every contractor to price the same drawing or explain any change. A total for “the whole roof” is not comparable when one proposal omits a porch, chimney detail or rear addition. Record reused materials and how shortages will be priced.
Resolve structure and covering as two decisions
New tiles or slates do not settle the condition of rafters, deck, battens or earlier alterations. Ask what can be checked before strip-off and what remains hidden. Agree who may authorise structural work and how evidence will be recorded. A contingency with a clear limit is easier to compare than an unrestricted instruction. Specialist design should be identified before the roof load or form changes.
Connect insulation to every edge
A different insulation build-up can change ventilation, eaves, ridges, rooflights and wall junctions. Ask for the layers and moisture-control route to be shown together. Confirm how thickness is handled at thresholds and retained roofs. Building-control responsibilities should name a person and route, not rely on a general statement that replacement is compliant. Keep the final specification with the handover records.
Check the proposed product against the pitch
Ask for the exact covering, underlay, battens, fixings, ridges, verges and flashings. Confirm that the chosen system suits the measured pitch and proposed exposure. Colour or profile may matter where a roof joins retained work or sits in a controlled setting. Use the full address for official checks and obtain product guidance for the actual assembly.
Make weather protection part of the programme
A strip-off sequence should explain how the property stays dry each day and what happens when weather interrupts work. Ask how materials and waste move through the site, where they are stored and which rooms or gardens need protection. Programme claims are more useful when they include scaffold, inspection points, deliveries and a process for hidden defects.
Set handover requirements before work starts
List the photographs, product information, approvals, waste records, invoice and workmanship terms required at completion. Agree how snagging is reported and when final payment falls due. Roofing Services in Reading may review an enquiry for referral, while the selected roofing business remains responsible for its design, quotation, contract and completed roof.
Check the scope before you decide
- Name every roof section.
- Ask why renewal is needed.
- Record what can be reused.
- Confirm the deck inspection.
- Define the insulation build-up.
- Check the ventilation route.
- Name the covering and fixings.
- Include each flashing detail.
- Price scaffold and protection.
- Plan temporary weather cover.
- State who removes waste.
- Set the payment stages.
- Agree how extras are approved.
- Record what remains excluded.
- Keep photographs before covering.
- Collect the handover documents.
- Read the guarantee boundary.
- Verify claimed credentials.
- Check the exact address.
- Save the accepted quote.
Make the survey evidence usable
Ask the surveyor to label photographs by roof section and relate each recommendation to an observed condition. Record the inspection date, weather and access method. If an area could not be seen, keep that limitation beside the price rather than treating it as resolved. A useful proposal separates facts, assumptions and optional improvements. It also states what would change after opening-up and who can approve the cost. Check the business name on the quote, insurance details, payment stages and cancellation terms where applicable. Verify claimed memberships with the body that issues them. Before work begins, save the accepted version and official address checks. During the job, retain photographs of details that will be concealed. At handover, compare the finished work with the scope, collect product and workmanship documents, and record any snagging route. These records matter whether the project is a small repair or a complete roof.
Questions to take into the survey
- What evidence supports the proposed cause and extent?
- Which roof areas could not be inspected?
- What access, protection and waste costs are included?
- How are hidden defects recorded and authorised?
- What exactly does the workmanship promise cover?
- Which official permission or building-control checks apply?
Write the answers beside each quote so different assumptions remain visible during the decision.
