Flat Roof insulation

Tucking in your roof

How to tuck in your roof correctly. “Tucking in your roof” is a term coined by @steveroofer in 2010, and it serves as a powerful metaphor for the meticulous process of insulating a roof to ensure optimal performance. Just as one would tuck in the edges of a warm blanket for a snug night’s sleep, the same principle applies to roofing insulation. When @steveroofer introduced this term, he was emphasising the crucial importance of sealing and insulating a roof properly. It’s not just about the quality of the insulation material; it’s about the attention to detail in making sure there are no gaps or openings that could allow drafts to compromise the thermal efficiency of your roof. Imagine your roof as a cosy quilt and the insulation as the warm filling. To truly benefit from its thermal properties, you must tuck in every edge and corner, just like you would with a blanket on a chilly night. This means meticulously sealing gaps, insulating vulnerable areas, and ensuring that the insulation forms a snug barrier against the elements. In a video on YouTube, @steveroofer demonstrated how to implement this concept practically, particularly when insulating behind the front fascia to form a warm roof. By tucking in the insulation [...]

New Roof Cost

Needs stripping and starting again, which adds to the new roof cost! New roof cost and how to keep the cost down. This is one of those things where the more you know, the worse it gets as you start to understand the complexity of what you’re about to do and the new roof cost and what’s involved in doing it properly! As a roofing surveyor, I’m constantly attending people’s houses after they have paid lots of money for new roofs, but I then have to tell them that everything is wrong and they need to completely replace the roof at some point, probably sooner rather than later. It’s mainly new loft conversions and extensions, as the trend at the moment (2022) is to get the builder to do all the work,  including the new roof work. Even if a roofer is brought in to do the roof and finish the project, they will be working with the mistakes that have probably already been made. These mistakes normally start way back in the project, even as far back as the drawing stage. Generally speaking, On small projects like extensions and loft conversions (small doesn’t mean low cost, I’m talking £50K, £100K even £200K projects), even if the people doing [...]

Thermal Bridging

Thermal Bridging of an Insulated Flat Roof Through the Front Fascia

I have watched a few of your videos in regards to flat ‘warm roofs’ on YouTube and have found them to be of great guidance with my current new build extension. Accordingly, I would be most grateful if you would answer a couple of questions that I have regarding your video posted on YouTube entitled ‘Thermal Bridging of a insulated flat roof through the front fascia’.

Warm Roof & Cold Roof Venting

Warm Roof & Cold Roof Venting

I had the conversion done 20 years ago. The flat roof has a very shallow slope and consists of joists, surmounted by furring pieces, transverse spacing battens for ventilation, ply deck with mushroom ventilators, and multiple felt layers.  It is also penetrated by a soil pipe near the condensing boiler vent. The ply deck appears to be in sound condition but blackened, presumably by condensation.
