 It should be noted that although it is not strictly necessary on very small roofs it is recommended that all installations be carried out by at least two persons for ease of installation and for safety.  The Ballasted method is not the only method of installation but it is the easiest and usually the cheapest, if however this method is not suitable for your installation please contact us whereby we can give you more information on other methods such as Fully Adhered and Mechanical methods.

Comprehensive instructions are supplied with every order. As well as a back up service in case you have any difficulties.

STEP 1
Firstly, the roof is swept clear of all loose chippings and debris and the substrate is checked for any water damaged timberwork and replaced if required.

STEP 2
The underlay is fitted to the roof .  

STEP 3
If the roof is designed to flow off into a gutter, a skirting will be attached.

  STEP 4
The rubber sheet is positioned on the roof approximately 6" back from the gutter edge and stapled or tacked to the outside edge of the sheet.                                                                                     

STEP 5                                                                                                                  
Whilst the batten is on the roof, the rubber sheet is draped down the wall and nailed or screwed through the batten, level with the roof. Make sure there is sufficient overlap each end to be able to fix down on the sides of the roof later

STEP 6
When the batten is in place the sheet is brought back over to form a secure internal fixing.

STEP 7
If the roof adjoins the house wall, this can be bonded up the wall and into the seam between the brickwork. Or under existing lead flashing if it is sound.

If the flat roof adjoins a pitched roof, the rubber membrane will be taken up under the tiles approximately 12" (minimum) and fixed to the roof timbers when the tiles are replaced it will look as follows.

STEP 9
Where there is an upstand to the edge of the roof, the old felt will be removed where it overlaps the fascia board and the rubber membrane will then be bonded up and over the upstand and 2" down the fascia any surplus should then be removed. The rubber should be folded tidily around the corners and fixed in place. The aluminium trims are then fitted to all upstands fitted this is best done through the front face of the trim but fixings can be applied through the top face, if the upstand is large enough and care is taken to ensure a water tight seal.

STEP 10
Once the rubber membrane is fixed and in place, it only remains to ballast the roof using either rounded gravel or lightweight patio flags, providing the roof is suitable. Other mechanical and fully bonded systems are available if required.
