Reviewing the work and Quality Assurance
Roofing is a technical and complex trade discipline with opaque rules and best practice standards. Reviewing roofing work can be highly subjective, and there are tolerances, trade-offs and compromises inherent in almost every installation. Once roofing works have been completed, it is important to carry out a thorough review of the installation before making the final payment.
A new roof contains dozens of technical elements and, while many require specialist knowledge to assess properly, understanding the most important visual indicators will help consumers form a reasonable view of whether the work appears tidy, sound and compliant. A primary focus should be the roofing sheets themselves. These should be laid straight, square and evenly, with no obvious kick-outs, crooked lines or alignment issues. Overhangs into gutters should be consistent, stop-ends should be folded correctly, and sheet laps should sit neatly without visible gaps. Minor marks or small cosmetic imperfections are normal, but sheets should be free from significant dents, scratches or abrasions that fall outside acceptable tolerance.
Fixings should follow a consistent and orderly pattern, be driven correctly, and not appear over-driven or under-driven. Flashings are another critical area to assess, as they provide much of the waterproofing detail on a roof. All flashings, including ridges, aprons, barges, headcaps and valleys, should appear straight, tidy and well fitted, with clean cuts and securely fixed edges. Where flashings intersect, the joins should look intentional and robust rather than improvised or loosely connected. Valleys should discharge fully into gutters, and flashings should sit beneath cladding or weatherboards where required, ensuring water is directed away from the structure.
Roof penetrations such as pipes, vents, skylights and chimneys are common points of vulnerability. These areas should be protected using appropriate Dektites, back-trays, diverters or flashing kits, depending on the penetration type. Rubber and metal components should sit flush, appear securely fixed, and be sealed carefully without excessive use of sealant. Penetrations should appear integrated into the roof rather than roughly cut or retrofitted.
Where gutters have been replaced or modified as part of the works, they should appear straight, have a consistent fall, and be free from visible dents. Joints should be neat, droppers should sit level, and bracket spacing should look uniform. While internal gutter performance may not be immediately visible, the overall impression should be one of alignment, order and careful workmanship.
Finally, the overall presentation of both the roof and the site is important. No loose screws, metal shards or rubbish should be left behind. Metal swarf should be cleared from the roof surface and gutters to prevent rust staining and degradation of the paint and galvanisation over time. The finished roof should present as straight, tidy and professionally executed. While consumers are not expected to possess technical roofing expertise, assessing these visual cues helps identify whether the work appears to have been completed with the care and attention a new roof requires.
Roofbuddy helps by offering a comprehensive 69-point quality assurance assessment and reporting framework carried out by an independent LBP-qualified roofer.

Consumers can review the assessment framework and sample output reports in advance. The purpose of the report is to provide both quantitative and qualitative feedback on the installation, confirm that Building Code requirements and industry best practice have been met, and give consumers confidence that the works have been completed correctly and in accordance with the quoted scope.

Rubbish, tidy up and removal of equipment and waste
Once installation is complete, the property should be left clean, safe and free of all debris. Roofing works generate a surprising amount of waste, including old sheets, flashings, timber offcuts, packaging, rivet stems, screws, cuttings and metal shards or swarf. These items can be hazardous if left behind, particularly in gardens, driveways and other high-traffic areas. Installers should remove all old roofing material, bag loose waste, and ensure no sharp or rust-prone fragments remain on the ground where pets, children or vehicles could be affected.
Gutters are another important area to inspect. During installation, metal cuttings, screws and fixings commonly fall into guttering, and if left unattended they can rust quickly, stain the new roof or obstruct outlets. A proper final tidy includes clearing all gutters, blowing down roof surfaces, and confirming downpipes are free-flowing and unobstructed. The surrounding work area should also be carefully checked for loose screws, nails or rivets that could puncture tyres or cause injury days or weeks after completion. A magnetic sweeper can also be used to pick up any metal items off the ground during the job or after the works are completed.
All scaffolding, edge protection and site equipment should be removed promptly once the works have passed inspection. The removal of scaffolding generally marks the true completion of the project, and access ways should be reinstated, gardens left undamaged, and the site returned to a neat and usable condition. A well-presented site at handover is often a strong indicator that the service provider has taken pride in their workmanship and closed out the project professionally.
Roofbuddy helps by identifying any outstanding tidy-up or removal actions within the quality assurance report and setting clear expectations with service providers around waste removal, site presentation, and the safe and timely removal of scaffolding and equipment.
Final invoice and warranty documentation
As a roofing project nears completion, it is common for the final invoice to arrive sooner than expected. Service providers are often keen to secure the final payment, so it should not be surprising if the invoice is issued before every last detail has been completed. Before paying the balance in full, it is important to confirm that all aspects of the job have been finished to a satisfactory standard, as outlined in the earlier sections of this guide. Where there are only minor outstanding items, it may be reasonable to make a partial or progress payment, provided enough funds are retained to fairly cover any incomplete work until those items are resolved.
Once final payment has been made, warranty documentation becomes the last critical step of the process. Manufacturer warranties are often issued only after installers submit completed job details, meaning this documentation typically arrives after payment has been received. While this is normal, it can sometimes be overlooked, so it is wise to set a reminder to follow up if the paperwork has not arrived within a reasonable timeframe. Consumers should ensure they receive both the manufacturer’s material warranty and the service provider’s workmanship warranty, and that these documents clearly state the scope of coverage, duration and any conditions attached. These warranties are essential if issues arise in the future, making it important to confirm they are accurate and aligned with the quoted specifications.
Roofbuddy helps by supporting consumers through the completion, quality assurance and final invoicing stages where required. We also liaise with service providers and, where necessary, manufacturers to ensure warranty documentation is issued correctly and invoicing accurately reflects the quoted works.
