How to Identyify & Repair Asphalt Shingle Splices

Splice Shingles used to keep material moving during the manufacturing process should be discarded but they almost always end up installed on the roof.

Spliced asphalt shingles are a factory defect - and were not supposed to have been installed.

The occurrence of spliced shingles on an asphalt shingle roof will be rare and multiple spliced-shingles quite rare. This defect is very unlikely to be a substantive roofing defect though if the splice is left un repaired a local leak and related water damage could occur.

We recommend simply replacing the damaged shingle with a new shingle.

Temporary roof repair to prevent roof leaks at a splice-shingle can be made by sliding a piece of metal flashing under the damaged area.
