THE ULTRAFLEX FLAT ROOF SPECIFICATION

In order to ensure that your Ultraflex flat roof system wil last a lifetime and provide a totally waterproof solution, we take many steps in the application process.

A typical flat roof job specification would be :-.
  • All existing stone chippings, felt coverings etc, will be cleared from the roof area. Substrate, usually chipboard, will then be stripped to expose the main roof joists.
  • Roofs suffering from poor drainage will be dealt with, usually by the use of timber firring pieces fitted to existing joists to give a fall to the new deck.
  • The roof area will then be re-decked with 3/4" (18mm) exterior grade plywood which will be securely anchored with 3" annular ring shank nails and / or 3" plated wood screws.
  • Specially made, pre-moulded, edging trims, wall fillets, gulley mouldings will be fixed into position.
  • Glassfibre mat of 4oz density will be tailored to fit the whole roof area. The mat will then be impregnated with polyester resin onto the new deck to form a seamless GRP membrane.
  • Once curing time has elapsed, usually between 1 - 4 hours depending on ambient temperature, a polyester resin gel coat in a chosen colour will be applied to the whole roof area.
  • Where a flat roof meets a brick wall, a chasing will be cut into a chosen coarse approximately 1.5" deep. Glassfibre and rein flashing will be tailor made to fit into the chasing. The chasing will then be re-pointed with conventional sand / cement mortar.
  • Where a flat roof meets a tiled roof, as in the case of a dormer construction, Glassfibre membrane will be extended up and under the tiled roof area between 6 - 12".
  • All waste material and debris will be removed from site by ULTRAFLEX.
  • Finally the owner shall be issued with a 25 year, written, transferable guarantee which will cover the costs of all materials and labour.
