Winter is hard on every home, but manufactured homes take a particular beating. The combination of lighter framing, exposed underbellies, metal roofing, and vinyl skirting means that freeze-thaw cycles, wind, and moisture can cause damage that goes unnoticed until it becomes expensive. A solid spring maintenance routine catches those problems early — before a small roof leak turns into rotted subfloor, or a torn vapor barrier invites a family of raccoons to move in underneath your living room.
This checklist covers 16 tasks organized by area. Most are straightforward enough for a Saturday morning. I have included time estimates for each one so you can plan your weekend (or spread it across a few). The whole list takes roughly 4 to 6 hours for a standard doublewide — a small investment to protect the home and land you own.
If the maintenance list feels longer than the home is worth, we understand. We buy manufactured homes on private land in Indiana — any condition. Call Roger at (502) 528-7273.
Exterior Maintenance (5 Tasks)
1. Roof Inspection and Cleaning
Time: 30–45 minutes
Your roof is the first line of defense, and manufactured home roofs — whether metal, shingle, or rubber membrane — are thinner and more vulnerable than what you would find on a site-built house. Walk the perimeter and look up. On a metal roof, check for lifted seams, rust spots, and any areas where caulk has pulled away from vents, skylights, or the ridge cap. On a shingled roof, look for missing, curled, or cracked shingles. If you can safely get on the roof (and it is structurally rated for foot traffic — not all are), check around every penetration: plumbing vents, furnace flues, and antenna mounts.
Clear any branches, leaves, or debris that accumulated over winter. Debris holds moisture against the roofing material, which accelerates deterioration. While you are up there, check that all roof vents are clear and not blocked by bird nests or leaves.
2. Skirting Check and Repair
Time: 20–30 minutes
Walk the entire perimeter and inspect every panel. Vinyl skirting cracks in cold weather and gets pushed in by wind, animals, and lawn equipment. Look for panels that are cracked, missing, warped, or pulled loose from the track. Gaps in the skirting are an open invitation for animals, cold air, and moisture. Replace damaged panels and reattach any that have popped out of the bottom track. Make sure the ground-level seal is tight all the way around — even a gap of a few inches gives critters enough room to squeeze through.
3. Gutters and Downspouts
Time: 20–40 minutes
Not every manufactured home has gutters, but if yours does, spring cleaning is critical. Remove leaves, pine needles, and shingle grit. Run water through each gutter with a hose and watch for leaks at the seams and corners. Make sure downspouts direct water at least 3 feet away from the home — 6 feet is better. Water pooling near the foundation is the number one cause of soft spots under manufactured homes, and it is entirely preventable with properly directed downspouts and splash blocks.
If your home does not have gutters and you notice erosion or puddling along the drip line, consider adding them. Basic vinyl gutter systems are inexpensive and a weekend project.
4. Siding Inspection
Time: 15–20 minutes
Walk the exterior and look for cracks, dents, holes, or sections of siding that have pulled away from the wall. On older homes with aluminum siding, pay attention to the bottom edges where the panels meet the skirting — that transition point takes a lot of abuse from lawn trimmers and splash-back. On vinyl-sided homes, check for panels that have unlatched from each other and are hanging loose. Any opening in the siding lets moisture into the wall cavity, and manufactured home wall cavities are thinner than conventional homes, so water damage progresses faster.
5. Caulking Around Windows and Doors
Time: 30–45 minutes
Inspect the caulk around every window, door, and exterior penetration (dryer vents, cable entries, outdoor faucets). Winter temperature swings cause caulk to crack and pull away, leaving gaps where water and air can enter. Scrape out any old caulk that is cracked, dried, or peeling. Apply fresh exterior-grade silicone or polyurethane caulk. This is one of the highest-value maintenance tasks you can do — a $6 tube of caulk can prevent hundreds of dollars in water damage and noticeably reduce your energy bills.
Underneath the Home (4 Tasks)
6. Underbelly and Vapor Barrier Check
Time: 20–30 minutes
Remove a section of skirting and crawl under the home with a flashlight. You are looking at the underbelly — the fabric or plastic barrier that covers the bottom of the home and holds the insulation in place. Check for tears, sagging, or sections that have pulled loose. A damaged underbelly lets insulation fall out, allows moisture to reach the floor joists, and gives rodents a warm place to nest. Patch small tears with underbelly repair tape (available at manufactured home supply stores). Large sections of sagging material may need to be re-stapled or replaced.
While you are under there, look for any standing water, wet spots on the ground, or condensation on pipes. Standing water under a manufactured home is a serious problem that needs to be addressed before it causes structural damage.
7. Tie-Down and Anchor Inspection
Time: 15–20 minutes
Manufactured homes are secured to the ground with a system of anchors and metal straps (tie-downs). Indiana requires these to meet HUD wind zone standards. While you are under the home, check that all straps are tight, not rusted through, and still attached to their anchors. Loose or corroded tie-downs are a safety hazard, especially during tornado season — and in Indiana, spring is when severe weather starts. If you find damaged or missing tie-downs, call a licensed manufactured home installer for repair. This is not a DIY fix.
8. Plumbing Check for Winter Damage
Time: 15–20 minutes
Frozen pipes are one of the most common winter casualties in manufactured homes, because the supply lines run through the unheated crawl space. With the flashlight, follow every visible pipe run and look for cracks, bulges, drips, or green corrosion at the joints. Turn on every faucet in the house (one at a time) and watch the pipes underneath for leaks. Check the water heater connections and the washing machine supply lines as well. A slow leak under the home can go unnoticed for weeks and cause floor damage from below — the kind you do not see until the floor starts feeling soft underfoot.
9. Pest Inspection
Time: 10–15 minutes (during your crawl-under)
While you are already under the home, look for signs of animal or insect activity: droppings, chewed insulation, nesting material, mud tubes on the piers (termites), or ant trails. Manufactured homes are more susceptible to pest damage than site-built homes because the crawl space is dark, sheltered, and often has access points through damaged skirting or underbelly material. If you see evidence of termites or significant rodent activity, call a pest control professional. For prevention, make sure skirting is sealed, remove any wood debris or firewood stored against the home, and consider placing rodent deterrents around the perimeter.

Interior Maintenance (5 Tasks)
10. HVAC Filter Change and AC Prep
Time: 15–30 minutes
Replace the furnace/AC filter — if you have not changed it since fall, it is overdue. A clogged filter makes your system work harder, drives up your electric bill, and shortens the lifespan of the equipment. For the AC unit, go outside and clear any leaves, grass clippings, or debris from around the condenser. Straighten any bent fins with a fin comb. Turn on the AC for a test run before the first hot day so you can catch problems while HVAC technicians still have availability. If your system is older than 10 years, scheduling a professional tune-up ($75–$150) is worth the money — manufactured home HVAC systems run hard because of the homes' typically lower insulation R-values.
11. Smoke and CO Detector Batteries
Time: 10 minutes
Replace the batteries in every smoke detector and carbon monoxide detector, even if they are still chirping along fine. Test each unit after replacing the battery. Manufactured homes have shorter escape times in a fire than site-built homes — the materials burn faster and the floor plan typically offers fewer exit routes. Working detectors are not optional. If any of your detectors are more than 10 years old, replace the entire unit. They lose sensitivity over time.
12. Water Heater Flush
Time: 20–30 minutes
Sediment builds up in the bottom of your water heater tank over time, reducing efficiency and shortening its lifespan. Attach a garden hose to the drain valve at the bottom, run it outside or to a floor drain, and flush until the water runs clear. This is especially important if you have hard water (common in Southern Indiana). While you are at it, check the temperature setting — 120 degrees Fahrenheit is the recommended setting for both safety and efficiency. Also check the pressure relief valve by lifting the lever briefly. Water should flow freely and stop when you release. If it drips or does not flow at all, the valve needs replacement.
13. Window Seals Check
Time: 15–20 minutes
Open and close every window. Check the weatherstripping for cracks, gaps, or sections that have compressed flat and lost their seal. Look at the interior caulk line where the window frame meets the wall — manufactured home windows are set into thinner walls, so settlement and vibration can open gaps over time. Hold a lit incense stick near the edges on a breezy day; if the smoke pulls sideways, you have an air leak. Replacing worn weatherstripping is cheap and makes a real difference in your cooling bills through the summer.
14. Plumbing Leak Check
Time: 10–15 minutes
Open every cabinet under a sink and check for drips, water stains, warped cabinet floors, or musty smells. Run the water and watch the drain connections and supply valves. Check around the base of every toilet for soft flooring or discoloration — a slow toilet leak is one of the most common causes of subfloor damage in manufactured homes. Flush each toilet and make sure it fills and shuts off properly. Check around the tub and shower for loose caulk or grout. A few minutes of looking now can prevent the kind of floor damage that requires pulling the toilet and replacing subfloor sections.
Yard and Foundation (2 Tasks)
15. Grading and Drainage Check
Time: 15–20 minutes
Walk around the home after a rain and note where water pools. The ground should slope away from the home on all sides. Over time, soil settles and erosion can reverse the grade, directing water toward the foundation instead of away from it. Add fill dirt where needed and re-grade so water flows outward. Check that downspout extensions and splash blocks are directing water away, not dumping it against the skirting. If you have a persistent drainage problem on one side, a French drain or swale may be the permanent fix.
16. Steps and Deck Inspection
Time: 15–20 minutes
Check every set of steps, porches, and decks attached to the home. Look for loose boards, rusted metal steps, wobbly handrails, and posts that have shifted or sunk into the ground. Manufactured home steps and decks are typically freestanding (not structurally connected to the home), so they can settle independently. A wobbly step is a fall hazard, and a deck that has pulled away from the home creates a gap where water enters. Tighten bolts, replace rotted boards, and make sure handrails are solid. If your wood deck has not been sealed or stained in a few years, spring is the time to do it.

Frequently Asked Questions
At minimum, inspect the underbelly twice a year: once in spring (to catch winter damage) and once in fall (to prepare for cold weather). If you live in an area with heavy rain or known pest activity, quarterly checks are a smart idea. Look for tears in the vapor barrier, standing water, pest droppings, and any insulation that has sagged or fallen.
Roof inspection is the single most important task. Manufactured home roofs — especially older metal or flat membrane roofs — are more vulnerable to leaks than site-built homes. A small leak that goes unnoticed through spring and summer can cause serious structural damage to the floor decking and walls. Catching it early can save you thousands.
Most items on this checklist are DIY-friendly for anyone comfortable on a ladder and willing to crawl under the home. The exceptions are HVAC servicing (a professional tune-up is worth the $75–$150), any electrical work, and roof repairs beyond simple caulking. If you find structural damage to tie-downs, anchors, or the frame, call a manufactured home installer or inspector.
If you do everything yourself, budget $50–$150 for supplies: HVAC filters, caulk, batteries, vapor barrier patch tape, and pest prevention products. Add $75–$150 if you hire an HVAC tech for a professional tune-up. Total cost for a thorough spring maintenance session runs $125–$300 for most homeowners — far less than the repair bills you will avoid.
