Let’s look at your options if you want to replace an old roof:
Option 1: Stripping
Strip the roof of the old covering and replace with a new covering.
Now, if you start to strip the roof, you get all sorts of other options open up.
- Should I have a temporary roof put up over the old roof to protect the building?
- How do I get all the old materials off the roof?
- What is the cost of dumping the rubbish?
- What is the cost of stripping the roof?
- Stripping the roof will trigger part L1B of the building regulations, and I will have to insulate the roof.
Once stripped: Liquid Plastic can go over the old decking if it’s sound, or can go over insulation if the roof is going to be turned into a warm roof.
Option 2: Overlaying
- No need for a temporary flat roof over the top as the roof will not be opened up.
- No need for insulation.
- Only remove the old stones and prepare the surface of the old flat roof, ready for overlaying.
- Overlay the roof using Liquid Plastic
