Flat Roof Maintenance Agreement Checklist

The property manager says the latest leak call should be covered by the quarterly maintenance price.

Your technician says the last visit included removing leaves from two drains, photographing a loose counterflashing, and recommending a repair that was never approved. Since then, an HVAC company has run a condensate line across the membrane, a sign installer has added a penetration, and water has shown up in the stockroom after a thunderstorm.

The agreement says only “inspect and maintain flat roof.”

That sentence is carrying too much weight.

A useful flat-roof maintenance agreement tells the owner what each scheduled visit includes, what the report will say, which small housekeeping tasks are included, what always needs separate approval, and what happens when a leak is reported after hours. It also identifies the roof being serviced. “Main roof” is not enough when the building has three levels, two membrane systems, six drains, four rooftop units, and a rear canopy that nobody priced.

Start with a roofing contract agreement, connect each visit to a roofing work order, and deliver a roofing inspection report. The roofing forms catalog gives a small shop the rest of the document stack without turning the service plan into a full facilities-management system.

The agreement’s core promise should be clear: your shop will perform and document the listed work at the listed roof areas under the listed conditions. It should not quietly promise that the roof will never leak, every drain will always flow, every manufacturer will honor a warranty, or every emergency can be reached within an exact number of minutes.

Separate the agreement into four service categories

Small commercial building owners may hear “maintenance” as “anything the roof needs.” Roofers may hear it as “two visual inspections and light debris removal.” Put all four service categories in writing before the agreement starts:

This separation matters because inspection is not repair, debris removal is not drain-line service, and a service-plan payment is not automatic authorization to open the roof assembly.

Use a change order when the owner approves work outside the scheduled visit. If the finding needs pricing, send a roofing quote estimate that names the report, roof area, photo numbers, materials, limits, and approval deadline. Do not let a technician’s note—“recommend patch”—become disputed permission to patch.

Build a baseline roof record before pricing recurring visits

The first visit should establish exactly what you are agreeing to maintain. A one-page roof map and component list are more useful than a polished proposal built on “approximately 10,000 square feet.”

Use stable identifiers:

• R1 — main retail roof;
• R2 — rear stockroom addition;
• R3 — entrance canopy;
• D1-D4 — primary drains;
• OS1-OS2 — overflow scuppers;
• RTU1-RTU5 — rooftop units;
• P1-P8 — pipes, vents, conduits, or other penetrations;
• CR1-CR3 — curbs;
• PR1-PR4 — prior repair areas; and
• A1 — roof hatch, with other access points named separately.

Carry those IDs into every report, photo caption, quote, work order, invoice, and warranty notice. The office should be able to search R2-D3 and find the same location across visits.

The baseline should record:

If the owner cannot identify the membrane, warranty, installation date, or prior repair, write “not provided” or “not verified.” Do not invent a roof age from color and weathering.

The site-visit estimate checklist is useful for separating what your estimator observed, what the owner reported, what the proposal assumes, and what remained uninspected. That discipline belongs in the baseline because the first maintenance visit should not inherit every unknown as an included obligation.

“Flat” is not a complete roof description

Customers use “flat roof” for many low-slope systems. The agreement should name the installed system and roof area instead of treating all membranes and details alike.

For OSHA construction fall-protection purposes, 29 CFR 1926.500 defines a low-slope roof as a roof with a slope less than or equal to 4 in 12. That definition does not mean the roof has no slope, that walking conditions are safe, or that every roof task uses the same fall-protection method.

The system matters too:

NRCA’s roof repair and maintenance training outline covers different repair procedures for built-up, polymer-modified bitumen, EPDM, and TPO systems. That is a useful reminder for the agreement: “minor roof repair included” is not a material specification.

Set the visit schedule from the roof, not a slogan

“Twice a year” is common advice, but it should not be sold as a universal rule that fits every roof.

Build the schedule from:

• the exact manufacturer warranty or guarantee;
• system age and condition;
• prior leak and repair history;
• tree cover, dust, grease, chemicals, vegetation, or other exposure;
• drainage configuration and seasonal debris;
• rooftop HVAC, solar, sign, antenna, and tenant-service traffic;
• snow, freeze-thaw, hail, wind, heat, wildfire debris, and local storm patterns;
• lease, insurer, lender, owner, or consultant requirements; and
• the owner’s operating risk, such as inventory, food service, clinic space, electronics, or occupied units below.

Johns Manville’s current commercial roofing owner’s manual recommends checking the roof at least twice a year and identifies spring and fall as useful times. Its sample guarantee also recommends review after severe weather. Those are manufacturer-specific examples, not permission to copy the same cadence into every roof agreement.

Write the schedule as actual deliverables:

Two scheduled visual roof-maintenance visits per agreement year, targeted for April-May and September-October, subject to safe weather, access, and scheduling. One additional post-event inspection is available at the stated service rate and is not included unless listed in the pricing schedule. The exact warranty and manufacturer requirements remain controlling for the installed roof system.

If the owner wants a post-storm visit, define the trigger and who requests it. A National Weather Service warning for the county, a tenant’s leak report, visible debris, a contractor’s roof entry, and a known hail event are different triggers. The storm-damage roof inspection guide shows how to separate reported weather, visible conditions, temporary protection, and the later repair estimate without turning the roofer into an insurer.

Write the inspection route into the agreement

A repeatable route makes year-over-year photos and findings comparable. It also makes omissions visible.

A practical commercial low-slope route can include:

1. Confirm access, weather, occupants, rooftop activity, work permits, and safety conditions.
2. Review open items from the prior report.
3. Photograph the access point and general roof condition.
4. Walk the perimeter and edge conditions where safe and within scope.
5. Check parapets, coping, counterflashing, base flashing, terminations, and wall interfaces.
6. Review the field of each roof area for visible cuts, punctures, blisters, wrinkles, displaced material, coating changes, open laps, traffic damage, debris, or vegetation.
7. Check seams or laps using only the listed visual or approved inspection method.
8. Review drains, scuppers, gutters, downspouts, sumps, strainers, and visible drainage paths.
9. Review curbs, pipes, vents, pitch pockets, conduit, supports, sleepers, walk pads, and equipment interfaces.
10. Map new rooftop work, penetrations, stored material, abandoned equipment, tools, fasteners, or chemical discharge.
11. Review prior repairs and open recommendations.
12. Inspect authorized interior or underside-of-deck locations for reported stains or visible change.
13. Complete approved housekeeping.
14. Photograph final conditions, record exceptions, and assign each recommendation a priority and responsible party.

Carlisle SynTec’s PVC rooftop inspection guide uses a roof plan and a route through perimeter, seams, curbs, penetrations, and drains before a general field review. Your agreement can use that routing idea without pretending one manufacturer’s checklist applies to every roof system.

Define included housekeeping one line at a time

“Clean roof” creates an argument. A maintenance agreement should say which light housekeeping tasks are included and where the stop point sits.

An included list might say:

• remove loose leaves, twigs, paper, and similar hand-removable debris from the immediate area around listed drains and scuppers;
• bag and remove up to a stated volume or time allowance;
• return movable strainers to position when they are present, undamaged, and designed to be handled without repair;
• return displaced walkway pads only when no adhesion, replacement, cutting, or manufacturer procedure is required;
• remove abandoned loose fasteners or small sharp debris when safe;
• photograph before and after each listed drainage point; and
• report, but do not disturb, unknown chemicals, grease, animal waste, needles, broken glass, electrical hazards, heavy materials, vegetation rooted in the assembly, or items owned by another trade.

An exclusion list might say:

• drain-line snaking, jetting, plumbing diagnosis, or interior drain repair;
• removal of strainers, clamping rings, drain bodies, scupper liners, or sealed components;
• flood testing, hose testing, destructive testing, or moisture surveys;
• snow or ice removal;
• pressure washing or membrane cleaning;
• removal of pallets, pavers, solar components, vegetation systems, equipment, abandoned curbs, or construction debris;
• handling regulated, contaminated, sharp, biological, or hazardous material;
• repair of membrane, flashing, seam, coating, edge metal, drain, wall, masonry, HVAC, electrical, plumbing, or structural components; and
• hauling beyond the written allowance.

If a drain remains slow or ponded water is visible after accessible surface debris is removed, the report should say exactly that. Do not mark “drain cleared” if no flow test or drain-line work was authorized.

A useful note is:

R1-D2: Removed approximately half a bag of loose leaves from the strainer area. Strainer remained in place. No drain-line service or flow test performed. Water staining and sediment line extend approximately 7 feet east of D2; no standing water present at 10:35 a.m. Recommend owner arrange drainage evaluation if ponding recurs. Before and after photos 18-21.

That note records the included task without promising that the whole drainage system works.

Separate findings from repairs

Give the technician a short, consistent set of status labels:

Avoid a “seal as needed” allowance. Sealant is not a universal roof repair, and an unapproved dab can obscure a condition, use an incompatible product, interfere with a warranty, or turn a diagnostic visit into construction work.

The invoice label does not decide whether corrective work is ordinary maintenance, a repair, or a larger alteration under the locally adopted rules. The 2024 International Existing Building Code, Chapter 4 provides model-code requirements for repairs to existing buildings, but the adopted edition, local amendments, permit exemptions, and authority having jurisdiction control the actual job. Put the permit and code check in the repair approval path instead of promising that every “maintenance” item is permit-free.

When repairs are approved, give the crew a separate roofing work order with:

• report and finding ID;
• roof-area and component ID;
• approved repair method and material;
• manufacturer or warranty coordination;
• access and fall-protection plan;
• removal and substrate limits;
• pre-repair photos;
• weather and surface conditions;
• test or completion criteria;
• concealed-condition stop point;
• price or not-to-exceed cap;
• change-order contact; and
• final photo and closeout requirements.

If the owner declines the work, record the recommendation, quote number, decision, date, and any temporary status. The hidden-conditions and scope-gaps guide explains why a clear stop point is more useful than burying the unknown inside a lump sum.

Make warranty review part of the paperwork, not the sales pitch

A maintenance agreement is not automatically a manufacturer warranty program, and a manufacturer warranty is not a maintenance agreement.

The file should identify:

• the warranty or guarantee document actually reviewed;
• who the warranty names as owner;
• covered roof areas and components;
• installer or approved-contractor requirements;
• inspection and maintenance duties;
• leak-notice method and deadline;
• alteration, penetration, solar, equipment, or overburden notice rules;
• repair-material and repair-contractor rules;
• exclusions for drainage, walls, HVAC, structure, storms, traffic, chemicals, or third-party work;
• transfer requirements; and
• whether your shop is authorized to perform warranty work or is only documenting conditions for the owner.

Johns Manville’s sample Peak Advantage guarantee expressly says the guarantee is not a maintenance agreement, assigns routine inspection and maintenance responsibility to the owner, and includes specific notice, alteration, drainage, approved-contractor, and recordkeeping terms. Other manufacturers and warranty products differ. Read the document for the actual roof.

Your agreement can say:

Contractor will record warranty information supplied by Owner and will perform only the services expressly listed in this agreement. Contractor does not determine warranty coverage or guarantee manufacturer acceptance. Work subject to an active manufacturer warranty or guarantee will be quoted and performed only after the required notice, authorization, contractor-eligibility, material, and documentation steps are confirmed.

The contractor warranty guide and manufacturer pass-through guide help keep the roofer’s workmanship promise, manufacturer coverage, maintenance duties, and chargeable service separate.

Track everyone who goes onto the roof

Many commercial roof problems begin after the roofing crew leaves.

HVAC technicians, electricians, solar installers, sign contractors, telecom crews, pest-control technicians, window washers, property staff, tenants, and delivery crews may cross the membrane or add equipment. The maintenance agreement should ask the owner to keep a roof-access log with:

• entry date and time;
• company and person;
• purpose;
• roof area visited;
• equipment, materials, or chemicals brought up;
• penetration, curb, conduit, support, or attachment work;
• before and after photos;
• debris removed;
• incident or damage note; and
• property contact who approved the entry.

The roofer’s visit report should identify new rooftop work without guessing who caused it:

New conduit and support blocks observed between RTU-2 and west parapet; not shown in March baseline photos. Installer, date, penetration detail, and warranty notice not provided. No destructive review performed. Recommend owner identify contractor and obtain alteration records before approving roofing work.

Johns Manville’s owner guidance recommends limiting traffic to walk pads, keeping roof records, and notifying the manufacturer about roof modifications. GAF’s roof asset management guidance likewise highlights debris, water, drains, flashings, and wind-related conditions as recurring inspection concerns. Those examples support a simple business rule: the agreement should make rooftop changes visible before everyone calls the next problem a roof leak.

Price the agreement around deliverables and exceptions

The agreement price should be traceable to the scope.

Price inputs may include:

• number of buildings and roof areas;
• roof area and layout complexity;
• access method, escort, key, security, and tenant restrictions;
• travel, parking, mobilization, and minimum visit time;
• number of drains, scuppers, gutters, penetrations, curbs, roof levels, and prior repair areas;
• system types and active warranty requirements;
• included housekeeping allowance;
• inspection method and report depth;
• interior review, tenant coordination, or leak-history work;
• number of scheduled visits;
• post-event or emergency options;
• photos, roof-map updates, owner portal or delivery requirements;
• material, disposal, lift, equipment, or second-person requirements; and
• renewal and price-adjustment terms.

Show the owner what the base price buys:

Annual base: Two scheduled visits to R1 and R2; visual route listed in Exhibit A; review of D1-D6, OS1-OS2, perimeter, visible field, seams, penetrations, curbs, rooftop equipment interfaces, and prior repairs; up to 45 technician-minutes of listed loose-debris housekeeping per visit; mapped photos; one report within three business days; one remote review call.

Then show what it does not buy:

Separately priced: Membrane or flashing repair; drain plumbing; destructive testing; moisture survey; leak investigation outside the scheduled route; emergency dispatch; hazardous or heavy debris; snow or ice; overburden removal; lift or special access; permits; engineering; manufacturer inspection or administration fees; other-trade work; and return visits caused by denied access.

Do not promise an exact report or arrival time if the shop cannot consistently meet it. If weather or access moves a scheduled visit, send a schedule change notice that names the old date, reason, temporary status, new window, and owner.

Tie each completed visit to an invoice that references the work order and report. The agreement, visit record, approved repair, material receipt, invoice, and payment should tell one consistent story.

Put a repair approval ladder in the contract

Property managers want urgent conditions handled. Roofers need a person who can authorize the spending.

Use an approval ladder:

The agreement should name primary and backup approvers, contact methods, business hours, after-hours rules, and what happens when nobody answers. “Use best judgment” is not a price authorization.

If electronic approval is allowed, preserve the scope, price, sender, recipient, date, and acceptance record. The federal Electronic Signatures in Global and National Commerce Act generally prevents a signature, contract, or record from being denied legal effect solely because it is electronic, but it does not erase other applicable content, authority, consumer-consent, record-access, or state-law requirements.

Write emergency terms that a two-truck shop can honor

“24/7 emergency service” can sound like a guaranteed arrival even when it means only that someone checks voicemail.

Define:

• what contact channel starts an emergency request;
• who monitors it and during which hours;
• what conditions the office will triage by phone;
• whether the response commitment is acknowledgment, callback, dispatch decision, or onsite arrival;
• service area and weather or daylight limits;
• dispatch fee, hourly premium, minimum charge, materials, equipment, and cancellation terms;
• who may approve spending and the not-to-exceed amount;
• whether the technician may perform temporary stabilization;
• warranty or manufacturer notice prerequisites;
• unsafe-access and stop-work conditions;
• owner duties to protect people, contents, utilities, and interior areas;
• whether another emergency service or trade may be needed; and
• when the permanent repair quote will follow.

A realistic clause might say:

After-hours requests must be placed through the emergency number listed in this agreement. Contractor will use commercially reasonable efforts to return the request within 60 minutes; this is a callback target, not a guaranteed arrival. Dispatch depends on crew availability, travel, weather, safe roof access, site contact, and written approval of the emergency rate and spending cap. Emergency work is limited to safe, reasonable temporary stabilization expressly authorized at the visit. Permanent repair, concealed damage, interior restoration, electrical work, plumbing work, structural work, equipment work, and warranty-covered work require separate scope and approval.

If you cannot monitor a number all night, do not sell that clause. Offer next-business-day priority instead.

The emergency record should preserve:

• time and method of request;
• caller and authority;
• reported leak location and conditions;
• active hazards and owner actions;
• photos supplied by the owner;
• triage response;
• dispatch decision and reason;
• approved rate and cap;
• arrival, access, and safety notes;
• temporary work and materials;
• before, during, and after photos;
• remaining exposure;
• departure condition;
• owner acknowledgment; and
• permanent next step.

Roof access and safety stay job-specific

A maintenance agreement cannot contract away the employer’s safety duties.

The baseline should identify likely access and hazards, but the crew still needs a task-specific safety decision at every visit. Use a job hazard analysis and safety inspection checklist when the work and site require them. The work-at-height JHA guide explains how to put access, edges, openings, equipment, rescue, and stop-work conditions into the crew’s pre-job record.

The word “maintenance” does not decide which OSHA standards apply. OSHA’s clarification of maintenance versus construction activities explains that construction can include repair or replacement of existing facilities and that the distinction is fact-specific. The scale and complexity of the work, the materials and equipment involved, and whether the task keeps the structure in its existing state can all matter. Identify the actual task before choosing the controls, and account for any applicable federal construction or general-industry rule and OSHA-approved State Plan requirement.

For roofing work on low-slope roofs with unprotected sides and edges 6 feet or more above lower levels, 29 CFR 1926.501(b)(10) lists permitted fall-protection approaches. Other hazards and tasks can trigger other requirements. OSHA’s interpretation on roofing inspections and small repairs explains that the § 1926.500(a) exception is limited to qualifying inspection-only activity before construction work begins or after it ends. Once the visit becomes repair work covered by the construction standard, the repair’s short duration does not remove the fall-protection requirement.

The work order should let the technician stop for:

• wet, icy, greasy, excessively hot, or unstable surface;
• unsafe portable ladder or fixed access;
• unprotected edge, opening, skylight, or fragile panel not covered by the planned controls;
• lightning, high wind, heavy rain, snow, or poor visibility;
• energized equipment, damaged conductors, or electrical exposure;
• uncontrolled exhaust, chemical, grease, biological, or respiratory hazard;
• blocked hatch, locked access, missing escort, or occupant conflict;
• soft deck, structural movement, or unexpected opening;
• wasps, birds, animals, sharps, or other uncontrolled hazards; and
• a task that changed from visual inspection to repair without the required plan, equipment, or authorization.

Record the stop, notify the owner, and reschedule or re-scope. A blank “not completed” line is not enough.

Make the report useful to both the roofer and the owner

The report should be consistent enough to compare visits and short enough that a property manager reads it.

Use this structure:

The work-order photo guide provides a repeatable context-to-detail photo habit. For recurring roof service, use the same overview angles each visit where practical, then add finding-specific context and detail. Do not replace a written location with 200 unlabeled photos.

Example:

Visit: Agreement RM-26-014, Visit 2, WO-5803, July 19, 2026. R1 main retail roof and R2 rear stockroom roof.

Access and scope: Accessed through A1 roof hatch with property manager escort. Visual route and listed housekeeping completed at R1 and R2. No destructive testing, water testing, membrane repair, drain-line service, or equipment work performed.

Prior item: R1-PR2 west curb patch showed no visible opening when viewed by the same method used on the prior visit. Monitor at the next visit. This statement does not evaluate concealed moisture.

Drainage: R1-D1 and D2 had loose leaves around strainers; one bag total removed within agreement allowance. R1-D3 was clear. R2-OS1 had a plastic cup lodged at the scupper mouth; removed. No strainers, clamping rings, drain bodies, or lines opened or tested.

New finding F-07: R2-P4, new conduit penetration approximately 8 feet north of RTU-4, not shown in the April baseline. No destructive evaluation of the sealant or flashing method was performed. Installer, date, and warranty notice unknown. Photos 31-35. Recommend that the owner identify the installer and authorize a warranty and repair review.

Safety/limit: East 12 feet of R2 not inspected because grease residue created a slip hazard near exhaust fan EF-2. Property manager notified. Recommend cleaning by the responsible qualified vendor before return.

Decision: No roof repairs authorized. Quote requested for investigation of R2-P4 after warranty documents are provided.

That report makes the next action obvious without claiming the roof is leak-free.

Renew from the report history

At renewal, do not simply change the dates and price.

Review:

• visits completed, moved, denied, or canceled;
• leak and emergency calls;
• debris volume and drain exceptions;
• repeated findings;
• open and declined quotes;
• new rooftop equipment or penetrations;
• warranty changes or transfers;
• access and safety problems;
• response performance;
• repair spending;
• roof areas added or removed; and
• report recipients and approval contacts.

If two scheduled visits repeatedly turn into four drain-cleaning trips, revise the service instead of pretending the original scope still fits. If the roof is approaching replacement, say that the maintenance agreement covers inspection, housekeeping, and limited, separately approved repairs during the planning period; it does not restore the roof to new condition.

Finish the year with a short completion sign-off or annual service summary that lists visits delivered, reports provided, approved repairs completed, open recommendations, declined items, and renewal choices. That gives the next manager a usable handoff if the building changes hands or the property-management team turns over.
