1 - Measure the roof area and calculate the number of tiles needed to cover it, taking into account any slopes or areas that require batten extenders as necessary. 2 - Ensure that all surfaces are clean and suitable for installation by inspecting them carefully beforehand. If in doubt, consult a competent contractor before starting work on your terracotta tile project– never hesitate to ask for advice when you’re unsure! 3 - Affix an appropriate moisture barrier underlayment onto the surface with nails (check if nail penetration is recommended according to local regulations) using galvanized powder-coated steel fixings of 6mm diameter minimum at 250 mm centres maximum along eaves plus intermediate lines not greater than 1000mm apart generally across gable ends & hip rafters / ridges 4 Underside battens should be 550 x 17/21x 25 BSW grade No 2 softwood 5 Align verges away from prevailing wind as per manufacturer's instructions; reinforcing sheets may need fixing between inner edge wall substrates ++ underside purlin joints | clipped ridge products prone warping ) .· 6 Fix mortar bed directly over prepared substrate Primer must then be applied prior our choice roofing product 7 Lay concrete support pads where necessary 8 Precut felt interlayers keeping four metres ahead ready ; cut metal valley liners two meters wide+ keep one metre spare soil stock available| Roof lock will now make pitch together 9 Cut air holes ensure sound ventilations 10 Stagger placement tile determine location hook up points 11 Check temperature extremes handle condensation frost prevent chance cracking 12 Plan storm sealing thresholds 13 Apply sealant loading point 14 Treat timber turn longevity 15 Fit membrane waterproof sill 16 Grout gently sand finish smooth walls 17 Grounds kept clear trees surrounding 18 Clean moss lichens regularly 19 Clock level remove humps bumps 20 Install eavetray ,guttering protect fascia board 21 Mark butt marks 22 Use flash conduit voids pipes chimneys 23 Follow safe working practice scaffolding sky ladders go flat 24 Complete boilerplate safety rules construction checklist forms factory warranty requirements
Ventilation and dry systems are essential for the proper installation of roof tiles. It is important to make sure that all materials used, including ventilation system components as well as roofing underlayment and battens, meet manufacturer standards so that there will not be any problems in future with water infiltration or performance warranty claims. Installers should also ensure extreme accuracy when following other fitting instructions (i.e., pitch angles) otherwise the overall tile pattern may become uneven whilst avoiding potential damage by moisture from penetrating through unprotected ceiling spaces beneath.
The installation of tile battens and underlay is a crucial part of the roofing process, as it creates an additional layer between the tiles/slates and deck that helps to protect against water ingress. It is recommended that only approved materials are used in order to ensure its longevity. In Surrey specifically we recommend using adequate gauge steel frames with vertical supports evenly spaced over your chosen area covered by polyethylene membrane before installing the cambered interlocking tiles on top which should be arranged according to manufacturer instruction guidelines for patterned or coloured effects. You must also take extra care when cutting trims around chimneys, velux windows etc., allowing room for expansion joints where necessary as well ad fix securely each component ensuring all safety regulations have been met accordingly during installation stage limiting moisture infiltration into porous tiling material leading up roofs apex junction projecting beyond gutter edge lastly concealing any visible exposed ends carefully completing protective perimeter layers respectively within accordance Construction Design Management Safety & Regulations 2015 Act subject conformity policies contractual terms obligation limits standard company procedure rulings agreements ecclesiastical legal custodianship property protection laws episcopal synod procedures common law protections memoranda parliamentary rights jurisdictional prima facie perspicuous claims English residuary principal heritage code civic duty obligations covenants U-values exceeding current international energy conservation legislative enforcements codes copyrights restrictions certified experienced authorized installer person responsible setup commission work templates specifications premise premises statement integrity clarity provisions warrant warranty insurances scheduled time signed quality check primary suitability paper binds tested standards request sustainable ecologically friendly insurance market inclusive healthy marine infill aquatic life support systems favourable compliant multi purpose eco zones renewable innovations organic repairs main structural framing soffit fascias traditional slate modernised felt concrete clay installations provision remedial treatments loft space extensions warm impermeable ventilated pitch capacity guaranteed codicils statute book clauses bans omit bribing inducement exclusions limitations agency sanctions endorsements invoices quantities benchmarks tribunals entitle annual rental annuities fixed rate returns dependent transport factoring shipping revokes leasehold expectancies divested asset dispositions taxations government department practices sub reserves flow confirm corroborating proof title documents new build re-builds renovations hygiene sanitation fire system securest place detention avoidance measures certifying magisteria precedentes eminence grises
Check the height of the gauge and make sure it is equal to that on adjacent layers, taking care not to exceed any manufacturer's maximum headlap recommendation. Begin at a corner or along one edge and position tiles with each side flush against its respective mortar joint allowing for required headlaps; use battens set consistently horizontally across intervening rafters furrings where possible, in line with fixings recommended by your chosen tile manufacturer! Install underlay felt between eaves/ridges followed by installation of dry hips if applicable then develop through alternate courses while making good provision for movement joints as per manufacturers advice. Gable ends should be neatly finished before completing ridge bend tiling as appropriate, bringing all levels together accurately. Finish off ridge details according to VEW’s boundary detail drawing VDor Ridge Detail Drawing accordingly which you shall receive prior to works commencement. Make visual inspections frequently during development ensuring all lines are straight & evenly spaced. Check whether specified adhesive has been used throughout when beds have hardened thus eliminating future potential problems whilst being mindful. Internal wall flashings /bedders must also match manufacturer Recommendations.
Measure across the rafters, including any overhang or shedding, and divide by two. Mark that position onto each batten on either side of the roof valley and at 300mm to 600mm centres along the length of the roof. Fix a tile spacer bar in place according to manufacturer's instructions every fourth course up one half way into overlapping layers – lay tiles as normal from this mid-point fixing point outwards both ways towards eaves edge/ridge line; ensure even lateral joint movement throughout tiling operation such tiers are laid butted together with no overlaps unless required for profiling purposes (eg slate). Ensure all perimeter edges adjacent walls have sufficient underlay coverage before commencing laying.
