Overview
A leaking roof tile can cause water damage to your home. This guide covers safely locating and repairing a leaking tile.
Step-by-Step Fix
Before beginning any repair, ensure you have isolated power or water supplies. Clear your workspace, gather standard hand tools, and wear appropriate personal protective equipment (PPE).
- First identify where the water is getting in. Go into the loft during rain and look for water staining or drips on the roof timbers and insulation. Mark the approximate location on the roof. Water can travel along timbers so the leak may not be directly above the damp patch.
- Do not attempt to access the roof in wet or windy conditions. Wait for dry weather. Use a sturdy ladder and scaffold tower where necessary. If you are not confident working at height call a professional roofer.
- Once on the roof locate the damaged tile. Look for cracked broken or displaced tiles. Check the flashing around chimneys and vents for damage. If the tile is cracked replace it. If the flashing is damaged it will need to be repaired or replaced.
- To replace a damaged tile gently lift the tiles above the damaged one. Slide the damaged tile out. If the tile is nailed the nails will need to be cut with a hacksaw blade or tile ripper. Take care not to damage adjacent tiles.
- Slide the new tile into position. Ensure it overlaps the tile below in the same way as the original. If the tile needs to be fixed use a tile clip or nail it in place. For a quick repair use roofing cement to seal the tile.
- For a temporary repair apply roofing cement or flashing tape over the crack. This is a short term fix. Arrange for a permanent repair or replacement tile as soon as possible.
- Check the roof for any other signs of damage. Loose or missing tiles should be secured or replaced. Cracked flashing around chimneys should be repaired with roofing cement or replaced.
- Once the repair is complete monitor the loft area during the next rainfall. Check that no water is getting in. If the leak persists there may be another problem elsewhere on the roof.
- To prevent future roof leaks have your roof inspected every two to three years. Remove moss and debris from the roof. Replace damaged tiles promptly. Keep gutters clear of leaves so water drains properly.
- If you are unsure about any step or the roof is steep or in poor condition call a qualified roofer. Roof work is dangerous and should only be done by someone confident working at height.
