If your shingles are fishmouthed, they will be prone to breakage if someone walks on the roof.
Fishmouthing can be caused by defective shingles, improper flashing, improper nailing, and shoddy storage of the shingles prior to installation.
We prefer to have you call ahead to make an appointment to avoid a long wait, but do take "walk-in" appointments and "drop-off" exams if you do not have the time.
If your pet has an emergency we can start treatment immediately with your authorization.
After this time, thoroughly rinse the mixture from the roof using low water pressure.
