In other parts of the world, you can buy white EPDM to keep the summer temperatures down, but not in Blighty, so I had to use bog-standard black.

I've done everything I can to mitigate the summer heat on our 55m2 dormer flat roof (ventilated deck, woodfibre insulation, careful airtightness detailing), and whilst these have helped over summer, it could be better.

Does anyone have any recommendations for a reflective paint that works well on EPDM and is available in the UK?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18357&Focus=309395#Comment_309395 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18357&Focus=309395#Comment_309395 Wed, 01 Oct 2025 17:10:20 +0100 fostertom https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18357&Focus=309398#Comment_309398 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18357&Focus=309398#Comment_309398 Wed, 01 Oct 2025 19:13:01 +0100 Peter_in_Hungary
Otherwise is the roof flat enough to hold a couple of cm of limestone chippings - say 5 - 10 mm size?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18357&Focus=309400#Comment_309400 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18357&Focus=309400#Comment_309400 Wed, 01 Oct 2025 21:11:49 +0100 djh https://www.roofingkitsdirect.co.uk/2019/02/epdm-rubber-roofing-chapter-1-the-questions/ "Yes, you can paint an EPDM membrane! If you’re looking to paint an EPDM roof, it’s recommended to use acrylic paint specifically formulated for rubber surfaces. These paints adhere well and provide durable coverage. However, before starting any painting project, it’s always a good idea to consult the manufacturer of the EPDM membrane to ensure compatibility and to avoid any potential issues." Which sounds like good advice to me!

The google search also throws up this thread as well as your one on build hub.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18357&Focus=309402#Comment_309402 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18357&Focus=309402#Comment_309402 Thu, 02 Oct 2025 08:23:30 +0100 fostertom Posted By: Peter_in_Hungaryis the roof flat enough to hold a couple of cm of limestone chippingsReminds me of 'upside down' roof - insulation slabs laid on top of the weatherproof membrane, weighed down with gravel or paving slabs - instead of insulating in the joist zone beneath. That used to be all the rage (in 80s/90s I guess) but little heard of nowadays AFAIK?

On the horizon is paint-on solar PV - brilliant white will become the standard colour for all buildings (and vehicles), with every surface busy generating (or will it be matt black?).]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18357&Focus=309403#Comment_309403 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18357&Focus=309403#Comment_309403 Thu, 02 Oct 2025 08:36:28 +0100 revor

There does not seem to be a definate recommendation but gives a number of potential candidates for further exploration.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18357&Focus=309414#Comment_309414 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18357&Focus=309414#Comment_309414 Thu, 02 Oct 2025 18:04:51 +0100 djh https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18357&Focus=309423#Comment_309423 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18357&Focus=309423#Comment_309423 Fri, 03 Oct 2025 13:10:54 +0100 revor Posted By: djhAs does a general web search

I disagree.

Ask A1 is the only one I have tried there may be better ones for all I know.

The more you try and specify the more results you get with general search. You get results based on each word you include. Ask Ai does it for you. e.g I recently wanted a sealant adhesive to bond cement based guttering to a liner made of pvc. Ask Ai searches the possible sealants and gives you the most appropriate result. Do that with a standard web search you get a whole load of offerings and you have go through all their data sheets to find something to suit.

Try it Ask Ai next time you search
