Lead sheeting is one of the most durable roofing materials. In fact some lead sheets use the original method of molten lead on sand. This is especially useful in replacing parts of cathedral and church roofing to keep the appearance of these buildings authentic.

A good lead roofer should have an expert knowledge of the likeliest faults and be able to find the cause of these faults before carrying out repairs. A roofing contractor will make sure they assess the condition of the lead and how long it might last, before starting on repairs or replacements.

Signs to look for on a lead roof that needs repairing include serious splits or ripples, oversized pieces, poorly located fixings or worn out fixings, signs of corrosion and heating or insulation conditions.

Repairs

To cover splits, small sections of lead sheeting can be wedged carefully over them. Lap joints can be used to strengthen the lead. Roll ends can be a point of weakness and need to be cut out and replaced if they are worn down. Special care needs to be taken when using blow torches.

Thermal Shifting

This is important with lead roofs, as oversizing and overfixing can lead to failed roofing sheets. Thermal expansion in the winter and summer temperatures has to take place, otherwise roofs will buckle and crack. If you limit the size of the sheets, the thermal movement will be fairly small. On flat roofs it is best to fix bays on the top third of the roll, whilst on pitched roofs, under the lap joints. Thermal movement can take place with the use of copper retaining clips that are fixed to the roof.

Wind and Weight

If head fixings are not fitted properly, lead sheets can slip out of place. By thinking about the weight of the lead, and how much it is exposed to wind lift, this problem can be corrected. Cover head fixings with a lap joint that is suitable for the degree of the pitched roof.

Flashings and weatherings need to be securely fixed and fixing clips used to secure them, again taking into account the exposure to wind.
