In applications of Double-Lap Tiles for roof pitches below 60, two nails should be used to secure each tile. In addition, a clip should also be fixed and placed 40mm from the head or at every other course. For roof pitches of above 60 and including vertical clips must again also be fitted but this time they’re spaced 20 -25mm apart in an alternating pattern as close to corner hips as possible where there is space available with opposing 2 nails being driven into both sides of the bibbed portion on either side just like all normal tiles mentioned previously using double nailing techniques if needed accompanied by required clips
Double-Lap Slates in Surrey should have a minimum of two nails and clips for every slate, with extra care taken on steeper roofs to fix the double lap slates securely. If applicable, additional measures such as covering hook heads or copper disc rivets may need to be employed when securing these roof tiles at pitches greater than 75 degrees or lower than 30 degrees.
To ensure a secure, watertight fixing of wooden shingles and shakes in Surrey. 1 - Ensure two nails or staples are placed into each shingle/shake when centre-nailing like normal roof tiles. 2 - Use either stainless steel (type 304 or 316) fixings for optimum corrosion protection, longevity and reliability. 3 - On extra windy areas use adhesive clips after nailing to further increase the security of the seal – many new engineered wood designs have these already integrated onto them saving time & money on additional fixings. 4 - Replace any corroded fastenings with up-to-date zinc alloys if tackling an old property to avoid unnecessary repairs due to rust damage later down the line!
Hips in Surrey need to be correctly formed with the appropriate struts, trims and brackets. All hips should have fascia boards fixed along their edges at a maximum of 900mm centres and nailed securely into the support framework with 8 gauge circular nails or equivalent fixing clips. Where valley hip tiles are used then adhesive mortar must also be applied between each tile course; two mechanical fixings for every roof tile should also be provided using suitable galvanised wire ties or a similar approved product as an additional fastening element if required by wind uplift calculations specified in NF
In Surrey the standard practice is to use nails and clips to secure roof tiles. The exact number of nails used depends on whether you have plain or interlocking tiles, but typically a nail should be positioned in each corner, as well as in between every two adjacent tile joints (every 300–400mm). For extra support, metal clips are then inserted into pre-drilled holes near either end of long units and along both edges of valley lines where water runs off from multiple planes.
There are a variety of reasons your tiles may be falling off in Surrey. It could be due to age and wear, with mortar gradually wearing away. This can leave the roofing nail clips not secured properly as they should have originally been fixed during installation. Alternatively it could also result from extreme temperatures or weather conditions that would make tile slipping more likely over time combined with weak adhesion between tiles and their underlying surface support system (such as felt). Additionally, use of inadequate fixing materials such as back-pointing rather than felt might cause looseness, leading to an increased risk for slip-out events over time occurring at some locations on the tiled areas observed.
