Can you use a damp proof course for a new dry ridge installation?
I had a new dry ridge installed on my roof about 2 years ago. The installer appears to have used damp proof course material underneath the ridge tiles rather than the proper membrane that I would have expected. Will this material do the job or should I look to get it reinstalled with a specified dry ridge membrane?

The answer to your question is you will have to install a dry ridge matting system. Please contact me on gordon@dandgroofing.do.uk for more information.

You would require the breathable roll out matting to be installed with a dry ridge system, not DPM as this will not be vented. Should you require any further information please feel free to contact me either on here or by email on lee@premier-roofcare.co.uk

You only need hip trays on hips with dry membrane on hips and just dry membrane on actions top.

Hi, you will definitely need the breathable matting with the adhesive strips - although if it isn’t leaking then I’d leave it alone.
