    Hot laid asphalt

    Roofers

    I've got a largish terrace which has an asphalt roof, asphalt type boiled up from blocks in tar boiler. Presently part covered in GRP tiles. Tiles and asphalt have moved with heat and it looks very untidy. Terrace is laid over solid beam and block first floor so area needds to be water tight. Can tiles be removed and asphalt replced or is it better to remove both and relay with something else.

    "As an asphalt spreader myself, I would recommend the removal of tiles and asphalt and replace with new asphalt to a 20mm thickness. Asphalt is ideal for foot traffic.
    Hope this helps."

    "Hi Chris,

    There are other options such as GRP (fibreglass), although I would recommend that you replace with mastic asphalt as the block and beam substrate would not need to be prepared beforehand than you would have to do for GRP (boarded over with OSB3 ply), as you lay mastic asphalt directly to a sheathing felt. The advantage is that asphalt performs better on a concrete base as it remains at a cooler temperature and once painted/tiled, there should be no thermal movement thereafter."

    "Hi, it’s better to take it off completely and replace with a new touch on felt."
