Thinking about solar? Make sure your roof is ready
Solar panels are a great fit for homes in Midhurst, but the roof must be safe and sound before any brackets or rails go on. Here is a clear checklist from our local team to help you avoid leaks, loose fixings and costly rework. If you need a hand, speak to our Roofing Midhurst specialists for advice or a site visit.
Structural checks come first
Load capacity
Solar panels, rails and fixings typically add around 12 to 20 kg per square metre. A timber roof in good condition will often cope, but older rafters, historic timbers or previous alterations may reduce capacity. Ask a competent roofer to inspect the rafters, purlins and wall plates. Where there is any doubt, a structural engineer should verify compliance with Building Regulations Part A.
Sagging and movement
Look for uneven lines, cracked plaster at ceiling junctions or distorted ridges. Any signs of movement need investigation before installation. Extra weight should never be used to mask an existing problem.
Condition of the roof covering
Tiles, slates and metal sheets
The fixing system for solar relies on the covering being intact and predictable. Check for cracked tiles, delaminating slate, corroded sheets and insecure ridge or hip tiles. Replace brittle or mismatched elements so that brackets seat correctly and water is shed cleanly.
Underlay and battens
Lift a few tiles to inspect the underlay and battens. Look for tears, UV damage, rot and inadequate batten sizing. Defects here undermine waterproofing once penetrations are made for brackets. It is often sensible to renew small areas in advance rather than patch later.
Weatherproof fixings and detailing
Brackets and penetrations
Choose a mounting system designed for your exact tile or slate profile. Use manufacturer approved flashing kits, saddle flashings or purpose made seals. All screws must hit solid timber, not just the tile, and stainless steel fixings are preferred in our South Downs climate.
Water management
Check valleys, abutments and gutters for capacity and condition. Rails can alter how snow and heavy rain behave on the roof. Clear debris, refix loose gutters and renew perished seals so water flows away from the property.
Orientation, shading and wind
Pitch and aspect
A south or south west facing pitch in Midhurst performs well, though east and west arrays also deliver useful yield. Confirm the roof angle suits the frame so panels sit flush and loads transfer correctly to the structure.
Shading
Trees, chimneys and nearby buildings in the town centre can shade panels and reduce output. Trim vegetation where appropriate and consider panel layout to keep strings consistent.
Wind uplift
The South Downs can bring lively gusts. Ensure rail spans, bracket spacing and fixings meet wind uplift calculations for our exposure zone. A secure array protects the roof and the panels.
Ventilation, insulation and condensation
PV arrays can slightly reduce roof surface airflow. Maintain eaves and ridge ventilation to avoid condensation. Where loft insulation has been upgraded, confirm there is a clear air path above it. Good airflow protects timbers and preserves warranties.
Planning, conservation and compliance
Most domestic PV is permitted development, but parts of Midhurst fall within conservation areas and the South Downs National Park. Check for local constraints, roof visibility from the street and any conditions on panel siting. Make sure the installer is MCS accredited, electrical work meets Part P, and your documentation is collated for insurance and future sale.
Warranties and coordination
Solar fixings that disturb a roof can affect manufacturer or workmanship warranties. Agree responsibility between the roofer and the solar installer, keep photos of all details, and record the exact bracket and flashing types used. This protects you if you ever need a claim.
Safe access and aftercare
Use proper scaffolding with edge protection. Avoid breaking tiles by planning material routes to the roof. After the install, book a post-fit roof check to confirm every penetration is watertight, rails are level and there is no damage to ridges or verges. Annual visual checks, gutter clearing and occasional fixing torque checks keep the system sound.
