Victorian / Edwardian Roof Installation

1) Fit the first section of Ring Beam into position ensuring its correct location. Remember to fit the External Trim before positioning (or Integral gutter if used).

2) Join remaining sections of Ring Beam together using both the Pressed and Flat Steel Cleats.

3) Fix the Ring Beam to the Window Frames from the inside of the windows through into the Ring Beam using 4.8dia. Self-tapping screws at a maximum of 600mm between fixings.

4) Hook into position on the Ring Beam the Ring Beam Variable Support. Slide the appropriate number of double studs (for the rafter) and Single Studs (for the Hips and Gable Rafter) down the Ring Beam Variable Support. NOTE: The studs must be fitted to EACH individual Ring Beam Variable Support as they are fitted.

5) Whilst at floor level, ensure the Ridge Variable Support and the Ridge Glazing Trim has been positioned within the Ridge, and that the Nylon Threaded Bar has been fitted to the Spider Bracket. Slide the appropriate number of Double studs down the Ridge Variable Support for Rafter and Single studs for Gable Rafter.

6) Raise the assembled Ridge up to its correct height and temporarily support. Loosely fit the Gable Rafters complete with Wall Rafter Gutter to the Ridge and Ring Beam.

7) Fix the Hips complete with Spider Bar Moulding on to the Spider Bar. Fix the Hips onto the Ring Beam using Single Studs. Align the centre line of the Hips with the center of the Spider Rafters stud hole. Once aligned, tighten the Grub Screws.

8) Fix the Gable Rafters to the Wall using appropriate fixings, minimum 3 Places per Rafter.

9) Cut to length and fit the Eaves Beam Seal into the Ring Beam Variable Support. DO NOT remove protective tape at this time. (This may have been performed by your supplier).

10) Carry out the Lead Flashing. The method and style of this is left to the installer although the flashing should finish inside the Wall Rafter Gutter. DO NOT flash around the Ridge at this point.

11) Fit a Glazing Stop and End Cap (Rafter/ Hip or Gable Rafter) to each Glazing Bar using CRS8628 screws.

12) Fit the Glazing End Trim to the Glazing. If using Polycarbonate, peel back the protective film to enable the fitting of the End Trim. Seal End Trim using a suitable silicone sealant.

13) The order of Glazing should be done in a specific way. Panels that sit on a Hip should be done first. So in the example shown, glaze panels 1 to 5 or 1 to 8 before glazing any others.

14) To Glaze, slide the Glazing panel on to the Rafters/Hips and slide into the Ridge Glazing Trim if applicable (Remember to remove protective film if using polycarbonate). Remove the protective tape from the Eaves Beam Seal, pull back the Glazing Sheet to the Glazing Stop and seat onto the Seal. Pull back tape film 1-2 inches and fold to inside of conservatory. Position glazing ensuring it is sealed down on glazing stops. Peal away tape film and pat glazing down from outside.

15) Once the Glazing is in position the Hip Top Caps can be fitted, making sure they butt unto the Ridge End Sealing Assembly.

16) Fit the Ridge End Sealing Assembly.

17) Before fitting the Ridge Top Cap, apply a continuous bead of Stelmax gap filler to all areas of the Ridge Flashing Trim where the Top Cap will locate, then slide the Flashing Trim onto the pre cut Ridge Top Cap.

18) Apply a continuous bead of Stelmax gap filler to the opposite end of the Ridge Top Cap where the Ridge End Top Cap will fit and slide the Ridge End Top Cap onto the pre cut Ridge Top Cap and fix using Poly Top Screws.

19) Fit the assembled Ridge Top Cap onto the Ridge. Before positioning, apply a mastic/silicone seal to the areas of the Ridge Flashing Trim that butt up to the wall. Now secure the Top Cap into position.

20) Complete the Lead Flashing around the Ridge Flashing Trim.

21) The Finial and Crestings can now be slid down the Ridge channel.

Jack rafter installation

1) Slide the Jack Rafter Bar into the Jack Rafter as shown. DO NOT fix into place at this stage.

2) Place the Jack Rafter into position, locating the Jack Rafter Bar onto the Jack Rafter Fixing and onto the Double Studs at the Ring Beam End. Tighten all nuts.

3) Secure the Jack Rafter Bar in position as shown.

4) All glazing can now be carried out. When fitting the Top Caps, ensure that the Joint between the Hip Top Cap and the Jack Rafter Top Cap is sound.

5) Apply suitable all weather sealant around joint between the hip top cap and jack rafter top cap

P-shape roof installation

1) Before the installation of the roof commences, fit the fixing cleats to the Wall Plate as shown. It is not necessary to locate the screws through the holes in cleats.

2) Fit the Wall Plate Variable Support complete with Glazing Trim to the Wall Plate. Slide a Single Stud (for Valley) and Double Studs down the Variable Support for the Glazing Bars.

3) Move the Wall Plate into position and fix the back to the wall at a maximum of 600mm centres. Now fix the Ridge to the fixing cleats previously fitted on the Wall Plate.

4) Before fitting of the Valley commences, ensure that the Valley Double Sided Tape has been fitted in the position shown on both wings of the Valley. (Do Not remove the backing tape at this time).

5) Position and fix the first wing of the Valley ensuring the connecting lug is facing upwards. Do not fully tighten the nuts at this stage.

6) Now fit the other wing of the Valley ensuring that the assembly is in the centre of both the Ridge/Wall Plate and Ring Beam.

7) Pull back tape film 1-2 inches and fold to inside of conservatory. Position glazing ensuring it is seated down on glazing stops. Peel away tape film and pat glazing down from outside.

8) When glazing around the Valley, always start at the top near the Ridge and work down, i.e. in the order 1 to 6 on the example shown.

10) Slide a 30mm long M6 Bolt up the channel in the Valley and secure the Jack Rafters into position at both ends. Fully tighten the bolts at both ends of the Valley.

11) Fit the remaining Glazing Bars ready for Glazing.

12) When all Glazing is complete, the Glazing Bar Top Caps including the Valley Top and Bottom Caps can be fitted.

13) Once the Ridge and Wall Plate Top Caps have been fitted, the Ridge Top cap Corner Trim can be fitted. Apply Stelmax Gap Filler to the under side of the Corner Trim.

14) Locate the Corner Trim and fix using Poly Top screws in the position shown. Remove any excess gap filler.
