Special - $1200 off on roof replacements
J&J Roofing & Construction provides commercial roof inspections, repairs, maintenance, and replacement for offices, retail buildings, warehouses, multifamily properties, mixed-use buildings, and other commercial properties across Southwest Washington and Northwest Oregon.
Commercial roof conditions are evaluated at membranes or roofing surfaces, seams, roof edges, parapet walls, flashing, penetrations, drains, scuppers, and rooftop equipment curbs when those areas are accessible. The inspection findings help define whether localized repair, planned maintenance, or full replacement should be considered.
The proposed roofing system depends on the building, roof slope, existing assembly, drainage, insulation, rooftop equipment, project requirements, and warranty option. The written proposal identifies the selected materials, system components, installation scope, exclusions, and project-specific conditions.
Schedule a commercial roof inspection when you have an active leak, recurring water entry, storm damage, visible membrane or flashing problems, drainage concerns, or an aging roof that needs a documented plan. J&J will review accessible conditions, discuss the property’s operational requirements, and prepare a written scope for the recommended work.
A commercial roof inspection should document the visible condition of the roof surface or membrane, seams, flashings, penetrations, drainage points, perimeter edges, parapet walls, and rooftop equipment details that can be accessed safely. Interior evidence of water entry and available maintenance or repair history may also help identify likely problem areas.
Inspection findings can be used to prioritize immediate repairs, identify maintenance needs, develop a replacement budget, or determine whether additional evaluation is appropriate. The scope and limitations of the inspection should be stated in the written report or proposal.
Commercial roof leaks often develop at seams, drains, roof edges, parapet walls, flashings, penetrations, rooftop equipment curbs, and transitions between roofing materials. J&J evaluates the visible condition and recommends a repair scope based on the likely source of water entry and the surrounding roof condition.
Common commercial roof repair work may include:
Localized repair may be practical when the surrounding roof remains serviceable and compatible materials can be integrated. Recurring leaks, widespread deterioration, wet insulation, extensive flashing failure, or a roof that can no longer be repaired reliably may require a broader solution.
Planned maintenance can help a property owner identify developing problems before they become larger repair projects. The appropriate schedule depends on the roof system, age, repair history, drainage, rooftop traffic, building use, warranty requirements, and exposure to storms or debris.
When included in a maintenance agreement, service may involve reviewing accessible seams and flashings, checking drains and scuppers, documenting visible damage, clearing limited roof-surface debris where authorized, and completing approved minor repairs. The agreement should identify the inspection frequency, included work, exclusions, reporting, repair authorization, and pricing.
Commercial roof replacement may be appropriate when an inspection identifies widespread membrane or surface deterioration, recurring leaks in multiple areas, extensive seam or flashing failures, confirmed moisture within the roof assembly, damaged or deteriorated decking, repeated repairs that are no longer practical, or materials that cannot be integrated reliably.
Replacement planning should consider the existing roof assembly, insulation, drainage, penetrations, rooftop equipment, attachment method, code requirements, building operations, access, material delivery, debris control, and weather. J&J prepares a written scope that identifies the proposed system, project sequencing, exclusions, allowances, and available warranty or guarantee options.
A roof recover may be considered only when the existing assembly and project conditions are suitable. Additional investigation or design input may be required before a reliable recover or replacement recommendation can be made.
J&J evaluates the building, existing roof assembly, slope, drainage, insulation, rooftop equipment, exposure, access, and project requirements before recommending a system. Depending on the property and verified service scope, commercial roofing options may include:
The proposal should identify the manufacturer, product, membrane thickness when applicable, insulation and cover-board work, attachment method, accessories, flashings, drainage details, and warranty or guarantee option.
TPO and PVC are single-ply membrane systems commonly used on low-slope commercial roofs. Their seams are heat-welded, and a complete assembly may include the membrane, insulation, cover board, attachment components, adhesives, flashings, edge details, and prefabricated accessories specified for the project.
System selection depends on the building use, existing assembly, roof traffic, chemical or grease exposure, drainage, insulation goals, attachment requirements, wind-uplift design, and available warranty or guarantee options. J&J installs GAF roofing systems where specified in the written proposal. The exact GAF commercial products and system requirements must be identified for each project.
Standing seam metal roofing may be appropriate for commercial buildings with suitable slopes, architectural requirements, and project conditions. The proposal should identify the panel profile, metal type, finish, underlayment, flashings, penetrations, attachment details, ventilation where applicable, and warranty terms.

1. Project discussion and site review
J&J discusses the building, known leaks, repair history, operational concerns, roof access, and project goals before evaluating accessible conditions.
2. Written findings and proposed scope
The proposal identifies the recommended repair, maintenance, or replacement scope; the proposed roofing system; materials; exclusions; allowances; and available warranty or guarantee options.
3. Scheduling and operational coordination
J&J coordinates roof access, material delivery, staging, debris control, and work sequencing. The plan should address tenant, customer, equipment, and building-operation concerns that are known before work begins.
4. Repair, or replacement work
The approved work is completed according to the written scope, project specifications, applicable requirements, and conditions found during the project. Changes are documented and authorized through the agreed process.
5. Cleanup, review, and closeout documentation
The crew completes jobsite cleanup and a final review. J&J provides applicable project records, product information, and warranty or guarantee documentation required by the written agreement.
Available manufacturer warranty or guarantee options depend on the selected roofing system, installed products, assembly, attachment method, building use, contractor eligibility, project specifications, registration, inspection requirements, and the official documents. J&J will identify the options available for the proposed project in the written scope.
J&J’s workmanship obligations are governed by the written contract and applicable workmanship warranty documents. Review the manufacturer documents, exclusions, maintenance requirements, owner responsibilities, and J&J’s written terms before approving the project.
J&J Roofing & Construction provides commercial roof inspection, repair, maintenance, and replacement services across Southwest Washington and Northwest Oregon. Request an inspection to discuss the building, roof condition, operational requirements, proposed system, project scope, and available warranty or guarantee options.
Localized repair may be practical when the surrounding roof remains serviceable and compatible materials can be integrated. Replacement or a broader solution may be appropriate when deterioration is widespread, leaks recur in multiple areas, moisture is present within the assembly, or repairs can no longer be completed reliably.
TPO and PVC are single-ply membrane systems commonly used on low-slope roofs. Both use heat-welded seams, but product composition, performance characteristics, chemical-resistance considerations, accessories, and available warranty or guarantee options differ. The appropriate system depends on the building and project requirements.
Water entry often occurs at seams, drains, scuppers, roof edges, parapet walls, penetrations, flashings, rooftop equipment curbs, and transitions between materials. The visible interior leak location may not be directly below the exterior opening.
The project plan can address roof access, material delivery, staging, debris control, work sequencing, tenant or customer concerns, and coordination around rooftop equipment. The written proposal should identify known operational requirements and project limitations.
Available options depend on the selected system, products, assembly, contractor eligibility, building use, registration, inspection requirements, and official manufacturer documents. J&J will identify the options available for the proposed project in the written scope.
