Dad says the gutters are fine because water still comes out of the downspout. Then you find his extension ladder leaning behind the garage, exactly where he can use it without telling you.
Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.
The argument is not really about leaves. It is about ownership. Dad believes the person who notices the clog should handle it. You believe the person handling it should not be Dad. Unless somebody accepts the whole maintenance job, both positions leave him one dry afternoon away from climbing.
The side door is not another lecture about ladders. Give Dad a way to inspect the system from the ground, give a service company a precise job, and give one family member responsibility for checking that the work actually happened.
Start with the line you can hold
If Dad understands the choice and insists on doing his own work, being his son does not give you automatic authority to confiscate his ladder or hire work in his name. A power of attorney also does not automatically erase his right to decide while he can make the decision himself. The exact authority depends on the document and the circumstances. This is a boundary to verify, not a permission slip to improvise.
You can still control your own part. You can decline to steady the ladder. You can offer to arrange a ground inspection. You can pay a contractor yourself if Dad agrees to the work and everyone is clear about who signed and who owes the bill. If you are unsure who may authorize work at the house, read the document involved and ask a Missouri lawyer about that document before signing for Dad. The site's source notes collect the underlying authority and consumer guidance used for this distinction in one place.
Do not turn the conversation into a verdict on whether Dad is capable. Keep it on the job: "I am not asking you to give up the house. I am asking you to let me own the gutter check so you do not have to climb for it."
Inspect from the ground first
Walk the house during or just after steady rain if it is safe to be outside. Stay on the ground. Look for water spilling over an edge, water running behind a gutter, a downspout joint spraying against the wall, a sagging section, or discharge collecting beside the foundation. From a window, you may also be able to see standing water or plant growth. Do not lean out.
Then walk it again when dry. Photograph each corner, downspout, extension, visible joint, and place where runoff has marked the siding or soil. Number the downspouts on a simple sketch. "Back left downspout" is much harder to misunderstand than "the bad one."
A clear discharge at one outlet does not prove the whole system is open. Water can escape while another section overflows, a joint leaks, or an underground extension is blocked. Your inspection is a work list, not a declaration that the roof drainage system is sound.
If the only way to see a suspected defect is by climbing, stop there. Federal ladder guidance tells workers to inspect ladders, use stable footing, maintain contact while climbing, avoid overreaching, and watch for electrical hazards. Those workplace rules do not govern Dad doing a household chore, but they show why carrying tools onto a roofline is not a casual favor. The relevant safety material is identified on the Sources page.
Make every bidder price the same route
Do not ask three companies what gutter cleaning costs. Send each one the same sketch and ask for the same scope. The comparison should say whether the job includes all gutters, every downspout, elbows, above-ground extensions, debris removal, and a water-flow check.
Ask each bidder these questions:
Will you remove debris by hand, vacuum, air, or water? Where will that debris go? Will you disconnect elbows when a downspout does not pass water? Does the price include clearing the blockage, or only reporting it? Will you photograph loose fasteners, open seams, rot, damaged fascia, or sections that hold water? Are minor adjustments included? What requires a separate written approval?
If a downspout enters an underground drain, make the stopping point explicit. A gutter cleaner may confirm that water enters the pipe without agreeing to clear or diagnose the buried line. Write down who owns that next step if water backs up.
Also ask how the crew will reach the work, whether it expects to walk on the roof, and what it does near overhead service lines. You are not directing the company's safety program. You are finding out whether its planned access matches the house you actually have.
Check the company before the ladder comes off the truck
Get the legal business name, physical contact information, proof of liability insurance, and proof of workers' compensation coverage when applicable. Ask the insurer or agent to confirm coverage if the document is unclear. Do not treat a logo, a neighborhood reference, or the word "insured" as the document itself.
The written agreement should identify the property, scope, payment terms, cleanup, and who may approve extra work. It should also say whether repairs are included or will be quoted separately. Missouri consumer guidance recommends checking a home-repair company, putting the agreement in writing, and tying final payment to completion of the agreed terms. That guidance is listed with the other primary materials on the Sources page.
If Dad is the customer, keep the signature block honest. Do not sign his name. Do not casually add your own name beneath his unless you intend to become a party to the contract. If you are paying while Dad authorizes the work, have the agreement state those separate roles.
Stay for the water test
A bag of leaves on the driveway proves that somebody removed leaves. It does not prove that the system carries water.
Before final payment, compare the completed work with your numbered sketch. Ask for photographs of sections that cannot be seen from the ground. Have the contractor explain any gutter that still sags, leaks at a seam, pulls away from the fascia, or sends water against the house.
Ask for a controlled flow test through each downspout when conditions permit. Confirm that water emerges where expected and that above-ground extensions were reconnected. Do not accept "all good" as the record. Write down what was cleared, what was repaired, what was merely observed, and what remains outside the contractor's scope.
If the contractor finds damaged fascia, roof edges, or a buried drain problem, that is a new job. Get the finding in writing and decide who owns the follow-up. Do not let a gutter visit quietly become an open-ended repair authorization.
Build a maintenance loop Dad can see
Dad may resist recurring service because it sounds like somebody taking over his house. Make the arrangement smaller and more visible.
Choose one owner. That person keeps the sketch, photographs, contractor information, invoices, and unresolved findings. Choose observable triggers instead of relying only on a calendar: overflow during rain, a detached extension, water staining, visible sagging, or roof debris after a storm. A routine inspection can still be scheduled, but the owner also acts when a trigger appears.
Agree on the communication rule. Dad gets told before anyone arrives. Nobody enters the house without his permission unless a separate emergency arrangement applies. The owner sends him the completion photographs and explains any proposed repair before authorizing it.
Then deal with the ladder without pretending it vanished. Ask Dad where it is, what jobs he believes still require it, and whether he will call you before using it. Offer a ground-level substitute for each recurring job. If he agrees, tag a damaged ladder out of use or arrange lawful disposal with him. Do not secretly remove sound property and call the conflict solved.
If the gutter problem exposes a wider pattern of unfinished maintenance, use the site's Start Here page to separate the urgent job from the family argument. If you need a local aging, legal, housing, or caregiver doorway, use Local Help in St. Louis and verify what each organization actually provides.
Your next move tonight
Put the ladder conversation aside for ten minutes. Draw the house, number every downspout, and circle the place where you last saw overflow, staining, sagging, or standing water. Text Dad one proposal: "Let me own the ground check and get one written scope. You approve any work before it starts." If he says yes, send the same sketch and the same questions to the first contractor. That is the job now.
