Accurate Roofings Mastic Asphalt division are capable of carrying out not only traditional asphalt roofing and paving works to a variety of roofs and car park decks but we are also licensed to install Iko’s Permaphalt Polymer Modified Asphalt and Permascreed Mastic Asphalt Roof screed.
This material can be installed one day to form falls on a concrete slab or uneven roof planks where a traditional sand and cement screed cannot be used. The beauty of the product is that it has no curing time and can have either hot melt or a traditional felt roofing system installed straight away without having to wait for a sand and cement or concrete screed to cure offering speed of installation and also waterproof integrity of the building whilst the work is ongoing that a traditional roof screed would not provide.
We can operate with our own asphalt mixers or hot charge facilities depending on the size and access of the job.
