What is Roof in Roof Insulation?

Room in Roof insulation adds thermal protection to converted attic spaces, including sloped ceilings, vertical walls, and dormer areas. It improves comfort in top-floor rooms and prevents significant heat loss through the roof structure.

  • Cavity wall insulation
    After receiving a letter from Northern Retrofit informing me of the government scheme to improve insulation and that it was a free service, I was initially sceptic but decided to look into it further and, after a very pleasant phone conversation, I was assured it was ‘legit’ and went ahead with arranging cavity wall insulation which was carried out efficiently by a couple of very pleasant workers who made sure I had everything in place to keep my property sufficiently insulated also checking whether or not I needed ventilation/extractor fans which they were only too pleased to supply and fit at zero cost to me! Excellent service and I would not hesitate to recommend Northern Retrofit.

  • Room in roof insulation
    From initial contact to completion, the room-in-roof work done by Northern Retrofit on my house was completed to my total satisfaction. The workforce was efficient, friendly, and cooperative throughout the entire process. I would highly recommend this company to anyone considering similar work. One point to note is that, as with any plastering work, dust can get into the air, so it’s important to adequately cover furniture and belongings beforehand.

  • Cavity wall insulation
    Free cavity wall insulation and extractor fan in bathroom fitted quickly and professionally. Small leakage of beads in the cellar which they came back and sorted the same day I rang. No complaints whatsoever, rare to get a worthwhile service for free! Thank you

  • Cavity wall extraction
    First class service from Northern Retrofit. We had our old cavity wall insulation taken out, and replaced with new. We were happy from start to finish, and found them to be both friendly and efficient. A special thanks must be given to Lucy in the office, and Kelby and Elliott who carried out the work. We are very happy with the result, it has made the house so much warmer. Thank you.
