When a new construction project is completed, the roofing system should be handed over with more than a completed roof. The developer should provide the building owner with a complete roofing documentation package that explains what was installed, how it was installed, what warranties apply, and how the roof should be maintained.
Proper closeout documentation protects the building owner’s investment, supports future maintenance, and can be critical when filing warranty claims or performing repairs. For commercial buildings, roofing manufacturers commonly recommend maintaining inspection, maintenance, warranty, and repair records throughout the roof’s service life.
1. As-Built Roofing Drawings
The owner should receive final as-built roof plans showing what was actually installed. These drawings should identify roof areas, slopes, drainage locations, penetrations, equipment, expansion joints, roof edges, flashing details, access points, and other important components.
If the installed roof differs from the original construction drawings, the as-built documentation should reflect those changes. Accurate roof plans make future inspections, repairs, renovations, and replacements significantly easier.
2. Roofing Material and Product Documentation
The closeout package should identify the products and systems installed on the building. This may include:
- Roof membrane or roofing material
- Insulation type and thickness
- Cover boards
- Vapor barriers or air barriers
- Underlayments
- Flashing materials
- Sealants and adhesives
- Fasteners and plates
- Edge metal
- Roof coatings
- Walk pads and accessories
Product data sheets, installation requirements, technical documentation, and applicable approvals should also be retained. Major roofing manufacturers maintain documentation covering specifications, details, warranties, technical bulletins, and related product information.
3. Roofing Warranties and Guarantees
One of the most important parts of the handover package is the roof warranty documentation.
The developer should provide copies of applicable:
- Manufacturer warranties or guarantees
- Roofing contractor workmanship warranties
- Extended or enhanced warranties
- Material warranties
- Registration certificates
- Final warranty inspection documentation
The owner should understand the warranty term, covered components, exclusions, maintenance requirements, claim procedures, and whether the warranty can be transferred to a future owner. Warranty requirements can vary significantly by manufacturer and roofing system.
4. Final Inspection and Testing Records
The owner should receive documentation showing that the roofing system was inspected and, where applicable, tested before project closeout.
Depending on the roof design and project specifications, this may include records for membrane testing, seam testing, moisture investigations, adhesion testing, fastener verification, drainage checks, or manufacturer final inspections.
Any deficiencies discovered during inspection should be documented along with evidence that corrective work was completed.
5. Roof Maintenance Manual
A roof maintenance manual gives the building owner or facility manager instructions for protecting the new roofing system.
It should explain recommended inspection frequency, maintenance procedures, rooftop traffic requirements, drainage maintenance, acceptable repair methods, and restrictions on penetrations or equipment work.
This information matters because some roofing guarantees require documented inspections and maintenance. Johns Manville, for example, recommends keeping inspection and repair records and conducting regular roof inspections.
6. Contractor and Emergency Contact Information
The final package should include contact information for the roofing contractor, manufacturer representative, warranty department, and other relevant parties.
The owner should know exactly who to contact when a roof leak occurs and who is authorized to perform warranty-related repairs.
7. Construction and Closeout Records
Finally, the developer should retain relevant roofing invoices, change orders, approved submittals, inspection reports, photographs, repair records, and other closeout documents.
Final Takeaway
A new roof should not be considered fully handed over until the building owner has the documentation needed to operate, maintain, inspect, repair, and protect the roofing system. A complete package typically includes as-built drawings, product information, warranties, inspection records, testing documentation, maintenance instructions, photographs, and contractor contacts.
For developers, organizing these records at project closeout can prevent confusion years later. For building owners, the roofing documentation becomes the permanent record of the roof and an important resource for maintenance and warranty protection. A professional commercial roofing contractor such as Shieldline Roofing can also help owners understand the documentation and establish an ongoing roof maintenance program.
