As autumn sets in and temperatures begin to drop across the UK, now is an essential time to take a closer look at your roof. Roof sheeting is designed to withstand a wide range of conditions, but even the most durable materials can suffer wear and tear over time. Winter brings added challenges such as heavy rain, frost, high winds and, in some areas, snow and ice. Acting now can help prevent minor issues from developing into expensive repairs when conditions are at their harshest.
A well-maintained roof protects not only your property but also your energy efficiency and safety. Checking your roof sheeting before winter ensures your building remains watertight, insulated and structurally sound throughout the season. Whether your roof is made up of metal, fibre cement, bitumen, PVC or polycarbonate, giving your roof sheeting a thorough inspection before the cold weather takes hold will extend its life and maintain its performance.
By identifying cracks, corrosion or loose fixings early, you can avoid expensive emergency repairs or water ingress during storms. In addition, keeping your roof sheeting clean and free from debris improves drainage and reduces the risk of leaks or pooling water. A small amount of time spent now can save weeks of inconvenience later...
However, ignoring pre-winter roof sheeting maintenance can have serious consequences...
Moisture can penetrate through gaps or rusted sections, leading to damp, rot or mould inside your property. Damaged or missing fasteners can allow sheets to lift in strong winds. Neglect also accelerates corrosion, shortening the lifespan of your roof sheeting. The good news is that with a simple, practical checklist, you can easily protect your investment before the first frost arrives.
In our latest blog, Sheeting Giant have put together your go-to winter roof sheeting maintenance checklist, designed to help you keep your roofing in top condition and ready to withstand the harsh winter weather. From ground-level inspections to examining roof penetrations and even calling in the help of a professional - you'll be able to make sure your roof stays strong, secure and leak-free throughout the colder months.
☑️1. Carry Out A Ground-Level Inspection
Begin by walking around your property to spot visible problems such as sagging sheeting, uneven lines, or damaged fixings. A pair of binoculars can help you check hard-to-reach areas safely before you climb up.
☑️2. Inspect For Rust, Corrosion Or Flaking Paint
Pay special attention to metal sheeting. Any discolouration, bubbling or surface rust should be cleaned and treated promptly with primer and touch-up paint to prevent further deterioration.
☑️3. Tighten Or Replace Loose Fixings
Thermal movement can loosen screws and bolts over time. Tighten or replace worn fixings using compatible materials to avoid galvanic corrosion.
☑️4. Examine Ridge & Verge Flashings
Inspect ridge caps and verge trims for gaps, lifted sections or cracked sealant. Damaged flashings are a common cause of leaks during heavy rain.
☑️5. Clean Out Gutters & Valleys
Remove leaves, moss, and debris from gutters, box valleys and downpipes to ensure proper drainage. Blocked gutters can lead to standing water and overflow into walls.
☑️6. Check Roof Sealants & Joints
Sealants around laps, fasteners, vents and skylights can dry out or crack. Replace any failing sealant with a high-quality weatherproof product suitable for metal or fibre cement sheeting.
☑️7. Wash Roof Surfaces Gently
Clean dirt, algae, and moss using a soft brush and mild detergent. Avoid harsh chemicals or high-pressure washers that could damage protective coatings.
☑️8. Inspect Rooflights & Translucent Panels
Clean and check rooflights for cracks, yellowing or water staining. Clear panels allow more daylight in and help maintain energy efficiency during darker months.
☑️9. Examine Eaves & Overhangs
Make sure eaves sheets are intact and securely fixed. Damage here can allow wind-driven rain to penetrate under the roofline.
☑️10. Look For Water Stains Or Damp Inside
From inside the building, check ceilings, rafters and insulation for damp spots or visible leaks. Early detection prevents long-term structural damage.
☑️11. Assess Roof Ventilation
Blocked or missing vents can lead to condensation and damp problems. Ensure air can circulate freely beneath the roof sheeting to reduce moisture build-up.
☑️12. Trim Back Overhanging Trees
Branches rubbing against the roof can damage surfaces and coatings or trap moisture. Trim them back to maintain clear space above the roofline.
☑️13. Inspect Roof Edges & Parapets
Strong winds can lift loose edges. Confirm all cappings, trims and parapet flashings are well-secured and sealed.
☑️14. Check Roof-to-Wall Junctions
Where the roof meets walls or other structures, look for cracked mortar or degraded sealant that could allow leaks.
☑️15. Review Roof Insulation
Inspect insulation from within the roof space. Damp or compressed insulation loses efficiency, increasing heating costs during winter.
☑️16. Verify Gutter Brackets & Downpipe Fixings
Support brackets can loosen or corrode over time. Tighten them and ensure downpipes discharge water away from the building foundation.
☑️17. Check Snow Guard Or Roof Safety Systems (if installed)
For industrial or agricultural buildings, make sure snow guards, ladders or safety lines are intact and properly anchored.
☑️18. Examine Roof Penetrations
Vents, chimneys, flues and extractor outlets are potential leak points. Ensure flashings and collars are secure and sealed.
☑️19. Review Manufacturer Warranties & Maintenance Records
Keeping accurate records of maintenance helps preserve warranties and can assist with insurance claims if damage occurs.
☑️20. Schedule A Professional Inspection (if in doubt)
If you’re unsure about any issue or your roof is difficult to access, contact a qualified roofing contractor. Professional inspections can uncover damage and ensure safe, effective repairs before winter weather arrives.
Your roof sheeting plays a vital role in keeping your property safe and dry throughout the winter. Taking time to inspect, clean, and maintain it now can prevent expensive repairs later. By following this 20-point checklist, you’ll not only protect your roof sheeting investment but also improve performance, durability, and appearance for years to come.
