We don’t do much British Standard Mastic Asphalt these days, mostly its repairs to older roofs from time to time.
This one was too far gone to repair, so we removed the old asphalt and applied new BSS6925 roofing grade asphalt. The new asphalt is polymer modified, imported from England.
Here are some photos of the work.
