Repair, restore, or replace your commercial roof?

The right scope starts with the roof.

The best option depends on the existing assembly, moisture conditions, repair history, drainage, and your ownership timeline. RedCorn helps you compare the practical options and understand what each scope addresses.

A ceiling stain tells you where water appeared, but not necessarily where it entered. RedCorn Roofing investigates commercial roof leaks, documents visible conditions, and explains the work needed to address the likely source.

We work with property owners, managers, businesses, and general contractors in Central Indiana. Whether you manage one building or several, a clear scope helps you prioritize repairs, coordinate access, and plan your budget.

Commercial roof problems we investigate

• Open seams and punctures: separated membrane laps, tears, and localized damage that can let water into the roof assembly.
• Flashing and rooftop equipment: deteriorated details around HVAC curbs, pipes, walls, skylights, and other penetrations.
• Roof edges and terminations: loose or damaged edge metal, failing cover strips, and membrane transitions.
• Drainage concerns: blocked drains, scuppers, gutters, and downspouts, plus areas where standing water needs further evaluation.
• Recurring leaks: previous patches, nearby details, and possible water paths that help explain why the same interior area keeps getting wet.

Repair options for your roof system

The existing material and its condition determine the repair approach. Preparation and compatible materials matter; a patch that suits one roof system may not suit another.

What to expect from a roof assessment

1. Start with the building history. Tell us where the leak appears, when it happens, and whether repairs have already been attempted. Roof access details and existing warranty documents are helpful.
2. Investigate and document. We review accessible roof conditions and relevant details, connecting photos to locations and observed defects. If the source or concealed condition remains uncertain, we explain what further investigation may be needed.
3. Review a defined scope. Understand the proposed repair, pricing, limitations, and any related concerns before authorizing the work.
4. Coordinate the work. Plan access, tenant communication, and scheduling around the agreed scope and weather conditions.

When repair makes sense—and when it may not

A targeted repair can be a practical option when the defect is localized and the surrounding roof remains serviceable. Widespread deterioration, repeated failures, suspected wet insulation, or damaged decking can require a broader investigation and a different scope.

If replacement, a suitable recover, or restoration deserves consideration, we explain why. Coatings and surface patches are not substitutes for addressing underlying moisture or drainage problems. We also provide commercial roof replacement and maintenance planning when those better fit the building.

Commercial roof coatings & restoration

A coating may be an option for a suitable existing roof when the underlying assembly remains serviceable. RedCorn evaluates the roof material, surface condition, existing coatings, drainage, and signs of moisture before recommending a restoration scope.

• Evaluate suitability: identify compatibility concerns and whether further moisture investigation or adhesion testing is needed.
• Address the details: define cleaning, preparation, localized repairs, and treatment of seams, penetrations, and flashing as required by the selected system.
• Set clear expectations: explain the proposed coating system, scope limitations, and applicable manufacturer requirements before work begins.

Read our commercial roof coating assessment guide for suitability, preparation, cost factors, and warranty questions. Coating over a problem does not correct it. Wet or deteriorated components, unsound substrates, and drainage defects need to be addressed; some roofs are better candidates for replacement.

Commercial roof replacement

When repairs no longer provide a practical path forward, replacement offers an opportunity to address the roof assembly more comprehensively. RedCorn plans the scope around the existing roof, building use, roof access, and the owner’s budget and timeline.

• Evaluate removal requirements, existing layers, and any recover options appropriate to the assembly.
• Identify insulation, decking, drainage, flashing, and edge details that need to be included or investigated.
• Compare suitable systems, including TPO, EPDM, PVC, metal, and modified bitumen.
• Coordinate staging, tear-off areas, temporary weather protection, tenant access, and rooftop equipment considerations.
• Provide a written scope with pricing, exclusions, and a process for addressing concealed conditions.

A recover is considered only when the existing assembly, moisture conditions, applicable requirements, and selected roofing system allow it. Warranty options depend on the specified system and eligibility; they are confirmed as part of the proposal.

Maintenance & capital planning

Roof condition reviews can help you plan repairs before the next budget cycle. We can document visible issues, review drainage and vulnerable details, and separate current repair needs from items to monitor or plan for. For multiple buildings, findings can be organized by property or roof area.

Documentation for property managers

Useful reporting connects each photo to a condition, location, and recommended action. Findings can be organized by building for multi-building properties, helping owners and managers distinguish immediate repair needs from items to monitor or budget for.

Share vendor requirements, insurance documentation needs, access restrictions, and tenant considerations when requesting an assessment so they can be addressed before scheduling.

How to compare commercial roofing proposals

Compare the same roof areas and assembly in each bid. A lower total may cover different removal, insulation, flashing, or drainage work. Ask each contractor to identify these items explicitly:

• Existing roof: which layers will be removed or retained, and how concealed moisture or deck damage will be investigated.
• New assembly: membrane type and thickness, attachment method, insulation and coverboard, and the conditions required for installation.
• Edges and drainage: perimeter metal, wall and curb flashing, penetrations, drains, scuppers, and transitions.
• Occupied-building work: staging, access, daily weather protection, equipment coordination, and cleanup.
• Price and warranty: included quantities, exclusions, unit prices for concealed repairs, and the exact workmanship and manufacturer coverage offered.
