BC farmers ask a simple question every year: “How do I keep my barns, hay sheds, and equipment shelters performing through blizzards and heat waves?” The answer is rarely a single big upgrade. It is a set of practical, repeatable seasonal tips for maintaining farm buildings that keep fabric structures safe, efficient, and profitable for decades.
Modern fabric barns and storage buildings are engineered to handle Canadian snow loads, wind, and ultraviolet (UV) exposure, and with good farm building maintenance, the fabric covers on these structures can routinely deliver 20-30 years of service life, while the hot-dip galvanized steel frames are designed to last a lifetime. The key is treating them as long-term capital assets, not temporary shelters.
Below, you will find a practical, Canada-focused guide you can implement on your farm this season.
Why Seasonal Maintenance Matters for Fabric Farm Buildings in BC
BC’s agricultural regions, from the wet coastal shores and mountains to the Prairie provinces and Central Canada, are seeing more climate variability: wetter springs, hotter summers, and more frequent extreme events such as atmospheric rivers, heat domes, and high winds. That volatility puts more stress on your buildings than a simple “normal winter” and “average summer” model.
That is where disciplined seasonal maintenance becomes a competitive advantage, not just a chore. When you understand how to maintain farm structures and buildings across the year, you:
- Protect livestock from drafts, condensation, and heat stress
- Protect harvested crops and feed from moisture and mould
- Avoid unplanned downtime from building closures and emergency repairs
- Extend the lifespan of your fabric cover and steel frame
- Preserve the resale and financing value of your operation
SpanMaster’s building solutions for agriculture are designed precisely with these realities in mind: bright, ventilated, weather-resistant structures backed by installation, repair, and re-cover services tailored to farm conditions in BC. A site-specific, engineered Canadian structure plus a simple seasonal routine is what keeps your barn “boringly reliable” when the weather is not.
Understanding How Fabric Buildings Behave in Winter
In winter, your building is working the hardest. Snow accumulates on the roof, wind pushes on the sidewalls and doors, and warm, humid air from animals or equipment meets cold exterior surfaces, generating condensation.
Engineered fabric buildings are designed for snow load and wind load in their local region, with steel trusses, hot-dip galvanizing, and tensioned fabric to distribute forces safely. Building profile matters here:
- Arch profiles spread load efficiently and help snow shed off both sides of the building, supporting wider clear spans with fewer internal columns.
- Peak profiles can be beneficial where additional interior headroom is a priority, for example, tall equipment or stacked bale storage.
Even with correct design, farm building maintenance in winter is still critical. Snow can drift unevenly; freeze-thaw cycles can cause ice dams; and small fabric nicks can grow under wind loading and cold.
This is where a simple, consistent winter checklist pays off.
Winter Checklist: Snow, Ice, and Structural Health
Think of winter tasks as “insurance” against structural problems and business interruptions. As part of your seasonal maintenance program, consider the following:
1. Snow Load and Safe Removal
- Inspect your roof after every major snowfall or wind event. Even in areas where annual snowfall averages 100-175 cm, drifting can create local spikes in load.
- Focus on drifted zones near eaves and on the leeward side of the prevailing wind.
- When snow must be removed, gently thump on the interior fabric to create vibrations that should get the snow sliding. Try to do this during large snow events if possible, rather than waiting until it stops snowing and loads have become extreme. If necessary to rake snow off a roof surface, work from the ground or approved platforms wherever possible. Remove snow evenly from both sides of the roof so you do not unbalance the frame or put extra tension on one side of the fabric.
2. Fabric Skin and Tension
- Walk the interior and exterior, looking for abrasions, small tears, or loosened tensioning hardware.
- Pay special attention to corners, door openings, and areas where augers, loaders, or tall equipment operate.
- Address damage promptly while it is still a simple patch or adjustment, instead of waiting until the wind turns a small issue into a larger problem.
3. Frame, Anchors, and Foundations
- Visually inspect posts, base plates, and anchoring systems for movement or heaving, especially after freeze-thaw periods.
- Check that anchor bolts are tight and that any ballast blocks or footings are not undermined by erosion.
- Around maintenance sheds and high-traffic zones, make sure access routes are cleared so inspection remains safe and easy.
4. Condensation and Ventilation
- Look for signs of condensation: frost lines, drips, damp insulation, or mould on stored items.
- Confirm that the ridge and side vents open and are not blocked by snow or ice. Good ventilation is critical to move warm, moist air out and bring fresh air in during winter.
5. Doors, Hardware, and Safety Systems
- Check overhead and sliding doors for ice accumulation, bent tracks, or stiff rollers.
- Test emergency exits and lighting, and verify that heaters, electrical panels, and fuel storage near the building are operating safely.
For a deeper dive into how weather-resilient barns protect your investment in these conditions, our article on weather-resistant buildings offers a good technical overview of how engineered fabric barns handle Canada’s winter extremes.
Preparing Fabric Farm Buildings for Canadian Summers
Summer creates its own stress test. Across BC, projections show more frequent and intense heat waves and changes in precipitation, meaning hotter barns and more severe storms on average.
In this season, maintaining farm structures and buildings is mostly about heat management, airflow, and UV protection:
- Livestock need cooler, well-ventilated spaces to reduce heat stress and maintain performance.
- Stored grain, seed, and hay need stable humidity and temperature to limit spoilage.
- Equipment and inputs need dry, shaded storage to prevent corrosion and UV degradation of plastics, hoses, and tires.
Fabric buildings excel in this environment when their natural ventilation and light-diffusing fabric are maintained properly. High-quality membranes transmit daylight but block most UV, and clear-span interiors support free airflow around animals and equipment.
We discussed how fabric buildings improve airflow on farms, explaining how well-designed venting in fabric barns supports animal health and reduces moisture-related maintenance headaches over time.
Summer Checklist: Airflow, Light, and UV Protection
A summer-focused list of seasonal tips for maintaining farm buildings will usually prioritize ventilation, cleanliness, and storm readiness:
1. Keep Air Moving
- Confirm that ridge vents, sidewall openings, and any mechanical fans are clean and operating.
- Walk the building on a hot afternoon and feel for “dead zones” where air is stagnant, often behind stacked bales or tall equipment, and reorganize storage to let air circulate.
- In livestock barns, work with your ventilation provider to fine-tune curtain heights and vent openings as herd sizes and stocking densities change.
2. Manage Natural Light and UV
- Inspect fabric for chalking, discolouration, or brittleness, especially on south- and west-facing exposures.
- Clean the membrane to remove dust, bird droppings, and organic growth that can shorten fabric life if left in place. Simple washing is often sufficient and is a cornerstone of long-term farm building maintenance.
3. Doors, Hardware, and Access
- Heat can warp door panels and frames over time. Check clearances, lubricate moving parts, and make sure seals are intact to keep dust and driving rain out.
- Around maintenance sheds, fuel storage, and chemical storage, ensure that drainage carries water away from foundations and traffic routes during sudden summer storms.
3. Storm-Readiness
- Inspect all anchoring points and tie-downs before storm season. Tight, correctly tensioned fabric performs better in high winds than loose covers.
- Remove loose debris, old pallets, or scrap metal near the building that can become airborne in high winds.
Align these tasks with broader operational goals. For example, small airflow improvements can raise animal comfort and productivity, while better shading and cleanliness extend asset life and cut repair bills. Our guide on how to maximize farm efficiency with custom-designed fabric structures explores this connection between building performance and day-to-day farm productivity in more detail.
Year-Round Inspection Routine and Documentation
The most effective farm building maintenance programs are simple and repeatable. Many Canadian guidelines for outdoor structures recommend at least semi-annual inspections, commonly in spring and fall, to catch small issues before they become serious.
For your fabric barns, that might look like:
- Spring Inspection:
- Review winter snow and ice damage.
- Check for leaks and staining.
- Verify that the foundation, anchors, and posts have not moved due to frost heave.
- Fall Inspection:
- Clean gutters, drainage areas, and yard surfaces.
- Inspect and tension the fabric before winter winds and snow.
- Service doors, latches, and safety lighting before shorter days.
- Event-Based Checks:
- Heavy snowfall, major windstorms, or extreme heat events should trigger targeted inspections focusing on load paths, anchoring, and fabric condition.
Record your findings like photos plus a short log of dates, actions taken, and who completed them. Over time, this simple documentation helps you decide when a cover should be re-tensioned, re-covered, or replaced.
As mentioned before, well-maintained fabric covers on these types of buildings typically last 20-30 years or more, and regular maintenance has been shown to extend that lifespan by 5-10 years compared to neglected fabrics. Check our guide to installing a fabric building that emphasizes how correct installation, plus ongoing maintenance, is what unlocks that long-term performance.
When Maintenance Reveals It’s Time to Upgrade
A good checklist does more than prevent problems; it also tells you when the current building has simply reached the end of its economic life.
Signs you are moving from routine farm building maintenance into “time to upgrade” territory include:
- Repeated leaks or fabric failures in the same zones
- Corrosion or deformation on steel structural members
- A barn that no longer meets current herd size, equipment dimensions, or biosecurity standards
- Rising energy or operating costs because the structure is hard to heat, ventilate, or keep dry
At that point, the right question is no longer just how to maintain farm structures and buildings, but whether a new prefabricated fabric or hybrid fabric-and-steel structure will deliver better returns over the next 50+ years.
SpanMaster specializes in modern prefab solutions that are engineered off-site and assembled quickly on your farm, minimizing disruption and delivering consistent quality. Arch-shaped buildings with fabric cladding can offer excellent snow-shedding and interior clearance for animals and equipment, while other profiles and hybrid designs suit different use cases.
If your inspection log keeps telling the same story, “this building is too small, too tired, or too risky”, that is a strong signal to speak with us about re-covers, expansions, or replacement structures.
