Definitely. What I meant to say is that 32 and 33 cm is not wildly different. So can I just proceed with the existing batten gauge (33 cm) without fear of issues like water ingress, felt failure etc? Given the slight size difference between the old and new Moderns, could this pose a problem...

Many thanks for this. The calculation and example provided was so helpful. Here is my calculation Gutter overshoot to Ridge - 4994mm Tile Length - 420mm* (*This is the size of the Marley Modern in 2023. The exisiting Modern on the roof is slightly shorter in length and width) Headlap -...

Thank you so much for the info. 1. Will the above technique/method for calculating the gauge still work if I am only replacing only the lower 7-8 rows of tiles? In total the roof on the front elevation has 16 rows of tiles. According to the Marley website, they state here that given the roof...

Is there a calculator on the ideal tile gauge for the pitch? As the roof has been fine many years without issue with this guage and the neighbours appear to have the same guage (terraced houses), wouldn't most just proceed with the existing batten gauge? Thanks. I very much doubt this is...

Thank you. Existing batten guage is 33 cm Roof pitch 3½/12 Thanks, I saw a number of recommendations with this membrane. I think you have even recommended it. With Permo Forte when lapping the two joins would you use Klober's tape or just batten it to secure it? The house is located in...

Thank you. So according to the Marley guide, the ‘eaves clips’ are optional (i.e. installer can either nail tile, use eave clip or both). Also, if fitted, eaves clips should be installed on the eaves course tiles. Given the above, it is baffling why the the existing roof tiles have eaves clips...

The Marley interlocking roof tiles appear to have a worryingly large gap (10mm) in many places (pics attached). Should I be concerned about this? Many of these gaps were filled with moss/ dust and soil. The neighbours (terraced houses) also have the occasional large gap Removing the tiles, I...

Which is generally better guys? Buying/fitting the (I) eaves felt support tray and (II) Eaves Comb Filler separately or buying a 3 in 1 part, like the link below, where they combine the eaves felt support, built in over fascia Vent and an eaves Comb Filler all together? 3 in 1 Eaves support...

Scaffolding delivered on Sunday, will get cracking this week. Thank you so much for the advice. Particularly the part about not thinking "I'll just do a bit more". Reading the above also helped remove the apprehension. Yes, I will use some 2x1 battens. I will just place the new battens...

I was going to use some dense polythene like DPC as opposed to an eaves tray. Are there any drawbacks to this? Is one more advantageous than the other? 8 weeks but company are flexible What kind of stick? So is it possible to stand on the scaffolding and just use a stick to remove the moss...

It's not even Christmas yet, but here comes the grinch :LOL: Fortunately not. Its a mid-terrace. It's a standard two storey house. Scaffolding arriving over the weekend. Excited and nervous at the same time :mrgreen: The tiles are Marley Concrete interlocking tiles They are flat looking...

Felt tears (in the bottom 4-5 courses of roof tiles) has led to a roof leak. Watching the below video, am I right in saying that the job is relatively straight forward for a competent diyer? i.e. 1. Remove roof tiles, remove battens and remove existing damages felt 2. Lay new breathable...

After noticing some damp patches on ceiling, I went in the loft to investigate. In the loft I found large tears in about five areas of the felt. The felt also felt (no pun intended) weak and almost crumbly in places. Before calling out a roofing contractor, could I get some suggestions on...

Apologies for the delay in updating this thread I am delighted to say that the pump was changed and the rads all work again. @terryplumb i can't thank you enough. Your knowledge and patience was amazing. A true gem.

You're a star, thank you. Contacted Vailliant and an engineer visit has been booked. Yes, rads worked fine prior to summer This experience has been great. As a family, we now feel confident/comfortable whipping rads off walls, draining the system, removing and fitting valves/TRV's. Will...

All the rads on the ground floor were removed. As advised, the pressure was kept high and the Flow and return from each rad were opened. There was a continual stream of water from each end. 15mm flexi tail did not fit on towel rail valce so unable to fully test. However, I am confident that...

Ground floor rad in dining room was drained. On the ground floor we have a living room, bathroom, dining room, then kitchen. One room after the other, in that order With the living room being the front room and kitchen furthest away in a single storey extension. Today we'll get the other...

Will get this checked out. Thanks.

One rad (ground floor) finally came off. Plasterboard was cutout (1) The system has been drained for over 1 hour now. 1. The upper floor rads appear to be fully drained 2. Some of the ground floor rads were holding a lot of water even after 1 hour. So valve was cracked open to drain the rad...
