A roof repair authorisation should be a single written document that references a measurable scope, permit responsibility and a written change order rule. Sign only after you have photo documentation and confirmation of the contractor’s licence and insurance. This one page becomes your record of what was approved, what it will cost and who is accountable if the job changes. A template and a step-by-step checklist follow below.
TL;DR:
- A comprehensive roof repair authorisation must specify detailed scope, exact materials, and clearly define permit responsibilities to prevent disputes over vague language.
- It should include photographic evidence at three stages of the repair process and attach key documents such as estimates, license proof, and permit information for accountability.
- Signatures should be obtained after verifying scope, permits, licensing, insurance, and that the written estimate matches the scope, with change orders approved in writing before additional work.
- The document must clearly outline who is authorized to approve change orders, specify emergency repair limits, and require photographic proof of concealed damage before billing extras.
- Using a one-page template that consolidates the scope, price, permits, change orders, and signatures streamlines legal record-keeping and reduces administrative delays.

What to include in the written authorisation
An authorisation only protects you if it names specifics, not general impressions. Vague language such as “repair the roof” invites disputes the moment concealed damage turns up. The document should describe the job at a level of detail that both you and the contractor can point to later without argument.
Start with scope: which roof planes are affected, the approximate area in square footage or roofing squares, the number of shingles or tiles to be replaced, and the linear footage of flashing or underlayment involved. A roofing scope of work that spells out these figures gives both parties a shared reference point rather than a general impression of “the leak near the chimney.”
Name the exact materials, including manufacturer and product line, and note that installation should follow the manufacturer’s written instructions rather than the crew’s usual habit. Attach photographic evidence covering three stages: pre-repair (the damage as found), mid-work (once old material is removed and any hidden issues are visible) and final (the completed repair from the same angles as the first set).
The authorisation should also fix practical details:
- Start date and expected duration, with an allowance for weather delays.
- Site access arrangements, including any need to secure pets or move vehicles.
- Confirmation that the described scope matches the written estimate, quantity for quantity.
- A note of any areas specifically excluded from this repair.
Step-by-step approval process: inspection to closeout
A repair authorisation works best as the outcome of a sequence, not a single signature taken on the spot.
- Document the damage first. Take timestamped photos of every affected area before any contractor visits, so you have an independent record to compare against later quotes.
- Get a written estimate that matches the scope. The quote should list the same measurable items you will put in the authorisation, not a lump sum with no breakdown.
- Verify licence, insurance and references quickly. A phone call to the licensing body and a request for a current certificate of insurance takes minutes and avoids a costly gap later.
- Check permits and HOA rules before signing. Some repairs need a building permit or a homeowners’ association sign-off before work can legally start.
- Sign the authorisation once scope, price and permit responsibility are settled, and keep a copy for your records.
- Require written change orders for anything beyond the original scope, each one signed before the additional work proceeds.
- Withhold final payment until you have completion evidence: final photos, permit close-out and, where relevant, a lien waiver.
Pro Tip: Ask the contractor for a contractor scope of work document rather than a one-line quote. It is the single easiest way to catch a mismatch between what you approved and what gets billed.
Permits, licensing and HOA approvals: what to check first
Permit rules sit with your local building department, not with the contractor’s opinion of what counts as a “repair.” Common triggers include the percentage of the roof being replaced, any change in roofing material, and work that touches structural framing rather than surface layers. These thresholds vary by jurisdiction, so confirm directly with the local authority before authorising permanent work.
HOA review, where one applies, typically looks at colour, finish and sometimes a physical sample submitted ahead of approval, and can add days or weeks to your timeline if not requested early.
Build a permit clause straight into the authorisation:
- The contractor is responsible for obtaining any required building permit before work begins.
- Permit paperwork and final inspection sign-off must be supplied before final payment is released.
- Any HOA-required colour or material approval is confirmed in writing before ordering materials.
Insurance interactions: authorisation versus insurer approval
Authorising a contractor to start work is not the same as an insurer approving your claim, and treating them as one step is where many homeowners get caught out. Your signature on the authorisation tells the contractor to proceed. The insurer’s approval, separately, determines what it will pay for.
Before signing, put in writing who covers the deductible, how any upgrades not covered by the policy will be billed, and what happens if the insurer’s settlement comes in lower than the contractor’s estimate.
- Confirm in writing whether the contractor will accept the insurer’s approved amount or bill you the difference.
- Ask the contractor to itemise any work that goes beyond what the insurer has approved, so it reads as a separate line rather than a hidden extra.
- If temporary emergency repairs are needed to stop further damage, photograph them immediately and keep the invoice separate, since insurers generally want that stage documented on its own.
Change orders and emergency work: controls that stop surprise bills
Concealed damage, most often rotten decking or hidden flashing failure, is the single most common source of authorisation disputes, and a written change order rule is the most effective guard against it. State clearly who is allowed to approve extras (you, specifically, not “whoever is on site”) and set a dollar limit above which the contractor must stop and get written sign-off before continuing.
- Define what counts as permitted emergency stabilisation, such as tarping an active leak, and cap its scope.
- Require photographic evidence of any concealed damage before it is billed as an extra.
- Make written sign-off, not a verbal phone call, the condition for any change order to be valid.
A ready-made change order template is a practical shortcut here rather than drafting the wording from scratch each time.
A one-page template you can copy and use
Job details: address, contractor name, licence number. Scope: roof planes, area, materials, flashing. Price: total and payment schedule. Permits: contractor to obtain, copies supplied before final payment. Change orders: written approval required above a set dollar limit. Emergency authorisation: tarping and stabilisation only, photographed and reported within 24 hours. Signatures: owner and contractor, dated.
Keep the structure to one page. Attach the pre-repair photos, the written estimate, proof of insurance and, once complete, the final photos and any lien waiver, all as numbered attachments rather than loose files in an inbox.
Pro Tip: Sign the authorisation on your phone rather than printing it. Mobile e-signature keeps the document, photos and payment record attached to the same file instead of scattered across email threads.
A staged payment approval structure works well alongside this template, releasing funds at defined milestones rather than as one lump sum. Because a form-to-contract workflow generates the authorisation from the same data you entered into the intake form, the scope, price and signatures stay as one unbroken record instead of separate documents that need to be reconciled later.
Common legal and liability considerations
The authorisation itself is a contract, and like any contract it needs to be specific enough to be enforceable. Vague scope language (“fix the leak”) is difficult to hold anyone to if the outcome disappoints, while a document naming materials, quantities and price gives both sides something concrete to point to.
Liability generally sits with whoever is licensed and insured to perform the work, which is exactly why verifying that licence and insurance before signing matters more than checking references or online reviews. An uninsured contractor who is injured on your property, or who damages a neighbouring structure, can leave you exposed if you authorised the work without confirming cover.
Warranty terms deserve the same specificity. Note whether the warranty covers labour, materials, or both, and for how long, directly in the authorisation rather than relying on a verbal assurance. If the job involves a permit, treat that permit as part of the legal record: unpermitted work can complicate a future sale or an insurance claim, regardless of how good the repair itself turns out to be.
Retain every document generated during the job, the authorisation, estimate, change orders, permit paperwork and final photos, as part of the property file. These records are often the first thing requested if a dispute, an insurance claim or a future buyer’s inspection raises a question about the work.
Contractors and property owners: who holds the authority
The owner holds the authority to approve scope, price and any change to either. That authority does not transfer to the contractor by default, even once work has started, which is why every change order needs the owner’s written sign-off rather than a verbal nod on site.
The contractor’s role is to propose the scope, execute it to the standard set by manufacturer instructions and local code, and flag anything discovered mid-job that falls outside what was authorised. A contractor who proceeds on concealed damage without stopping for approval has exceeded their authority, regardless of how reasonable the extra work might be.
For property managers acting on behalf of an owner or a body corporate, this split matters even more. A verbal go-ahead from an on-site manager carries far more risk than a written approval that specifies exactly what was agreed, because the manager’s authority to commit funds is often more limited than a sole owner’s. Treat any material substitution or scope change as something that needs the same written approval as the original authorisation, not a lesser one.
Typical timelines from authorisation to completion
Timelines vary with the size of the job, permit requirements and weather, but a general pattern holds across most straightforward repairs. Inspection and quoting typically take a few days from first contact to a written estimate in hand. Licence and insurance verification, done properly, adds very little time since it can happen the same day.

Permit processing is usually the slowest step when one is required, and this is where HOA review can also add meaningful delay if a colour or material sample needs approval first. Confirming these requirements early, before signing the authorisation, keeps them from becoming a surprise once the crew is ready to start.
Once permits and approvals are in hand, the physical repair itself is often the shortest phase for a standard patch or section replacement, with completion evidence, final photos, permit sign-off and any lien waiver, typically following within a short window after the last shingle goes down. Building this expectation into the authorisation upfront, rather than assuming everyone shares the same mental timeline, avoids the common friction of a homeowner expecting next week and a contractor working from a permit queue measured in weeks.
Communication practices that keep everyone aligned
Every material update, a scope change, a permit delay, a concealed damage finding, should exist in writing, not just in a phone call that neither party can later verify. This does not mean formal letters for every detail. A quick message summarising what was agreed, sent right after a site conversation, does the job and creates a timestamped record.
Set a single point of contact on each side before work starts. Multiple family members or property staff giving instructions to the crew is one of the more common sources of scope confusion, since a verbal instruction from someone without authority to approve changes can be mistaken for sign-off.
Agree on a response window for change order requests, particularly for anything found once work is underway. A contractor waiting days for approval on a concealed damage finding has little incentive to leave the roof exposed, so a same-day or next-day response expectation, stated upfront, protects both the schedule and the property.
Where an insurer is involved, loop them into major updates rather than assuming the contractor is handling that communication on your behalf. Claims move faster when the insurer receives photos and documentation directly, rather than secondhand through a contractor with its own timeline pressures.
Handling disputes during the authorisation process
Most disputes trace back to a mismatch between what was verbally discussed and what the written authorisation actually says, which is the strongest argument for keeping every material detail in the document itself rather than in memory. When a disagreement arises, the first step is to compare the disputed item against the signed scope and any change orders, not against what either party recalls being said on site.
If the dispute concerns concealed damage billed as an extra, photographic evidence becomes the deciding factor. This is exactly why the authorisation should require photos before any extra is approved, since without them there is no way to confirm the damage existed or its extent.

For disagreements over quality or completion, walk the job against the original scope line by line rather than relying on a general impression of the finished roof. A permit inspection, where one applies, offers an independent check against code compliance that can settle a dispute neither party can resolve alone.
Where a resolution cannot be reached directly, licensing boards typically offer a complaint process, and many jurisdictions provide mediation services for construction disputes before matters escalate to legal action. Keeping the authorisation, estimate, change orders and photo record organised from the outset is what makes any of these paths workable, since a dispute without documentation rarely resolves in the homeowner’s favour.
The quick on-site checklist
Before signing anything, run three checks: scope matches your photos, licence and insurance are current, and permit or HOA status is confirmed. Add one line on change orders and hold back final payment until you have completion evidence in hand. A simple digital workflow keeps these records together rather than scattered across texts and emails.

How KSign helps you get authorisations signed faster
Chasing a printed authorisation for signature, then a separate email for the deposit, then a folder of photos nobody can find later, adds admin that a straightforward repair job does not need. KSign turns the intake form you already use into the signed authorisation itself, then keeps the deposit, the change orders and the photo record attached to that same file.

For tradies and property managers running several jobs at once, this matters more than it sounds:
- Generate the authorisation directly from the job intake form, so scope and price never need retyping.
- Collect a legally binding e-signature and the deposit in the same mobile step, from a phone or tablet on site.
- Store photos, permit copies and every change order against the one job record for later reference.
Templates for common repair scopes are ready to adapt rather than built from a blank page each time, and Contract Automation turns your existing intake questions into a document without extra setup. Plans start on the pricing page, with Standard and Professional plans priced per month per seat.

FAQ
Do roof repairs require a permit?
Permit requirements are set locally and typically depend on the percentage of roof replaced, any material change and whether structural work is involved. Always confirm directly with your local building department before authorising permanent repair work, since assuming a small job is exempt can create problems at resale or claim time.
Do I need a permit to repair my roof?
This depends on your local building department’s rules, not on the size of the job as the contractor sees it. Ask the contractor to confirm permit status in writing as part of the authorisation, and require permit paperwork before releasing final payment.
Do you have to be licensed to fix a roof?
Licensing requirements vary by jurisdiction, but verifying current licensing and insurance before signing any authorisation is standard practice regardless of where you live. A quick check with the local licensing body, done before signing, is far cheaper than resolving a dispute with an unlicensed contractor afterwards.
What is the 25% rule in roofing?
Definitions of this rule vary by jurisdiction and building code adoption, and it generally relates to the portion of a roof that can be repaired before the work is treated as a full replacement for code purposes. Confirm the specific threshold and its implications with your local building department rather than relying on a general rule of thumb.
What should a roof repair authorisation include at minimum?
At minimum, it should name the measurable scope, the exact materials, the price, who is responsible for permits, and a written change order rule with a defined limit for extras. Attaching pre-repair and final photos, along with proof of licence and insurance, turns the document into a usable record rather than just a signature.
