Shingles made simple


Daniel Redfern of manufacturer Marley Eternit says that installing a timber shingle roof is not as hard as you might think, and offers a step-by-step guide


F


rom summer houses and self- builds, through to holiday homes and heritage projects, the demand for a natural timber aesthetic means there is growing opportunity and demand for builders and roofers who can install shingles.


Although often thought of as a specialist roofing material, with the right tools shingles are actually very easy to fit and can be done by anyone who can fix roof tiles. However, the way that you install shingles and the type of ventilation required will depend on what type of underlay you use – non- breathable (traditional) or breathable (vapour-permeable).


This guide shows how simple it is to install shingles, using the ShingleFix staple system as an example, with two different underlay methods.


STEP 1A: NON-BREATHABLE UNDERLAY WITH 25 MM EAVES VENT SYSTEM


Install a continuous rafter roll, over a fascia ventilator and felt support tray, to direct airflow below the underlay into the roof space. Dress the underlay down to bottom edge of the felt support tray and fix using a self-adhesive tape. Then continue to install the underlay in the normal manner.


STEP 1B: VAPOUR PERMEABLE UNDERLAY WITH 25 MM EAVES VENT SYSTEM (BATTEN SPACE VENT) This method does not require a continuous rafter roll. Instead install the felt support tray first, and fix the over- fascia ventilator over the top to direct airflow into the batten space, above the underlay and below the slates. Dress the underlay down to the bottom edge of the felt support tray, behind the over- fascia ventilator and fix using self- adhesive tape. Then install the underlay in the normal manner.


STEP 2A: NON-BREATHABLE UNDERLAY – BATTENS Non-breathable underlay does not need to be counter battened. The position of the first batten should be the batten gauge plus half the thickness of the

batten. The batten gauge thereafter is based on the pitch of the roof.


STEP 2B: VP UNDERLAY WITH COUNTER BATTENS Vapour permeable underlay needs to be counter battened to allow ventilation of the batten space above the underlay and below the shingles. The position of the first batten should be the batten gauge plus half the thickness of the batten. The batten gauge thereafter is based on the pitch of the roof.


STEP 3: SETTING OUT
