Great service from start to finish. The job was done quickly, very professionally and to a very high standard. The roof looks excellent and everything was left clean and tidy afterwards. Reliable, hardworking and clearly knows his trade. I’m very happy with the result and would definitely use JSB Roofing again. Thanks for a great job!

For a good few Years, I had a problem with rain coming into my house through my roof, I had a couple of Roofers try and fix this problem with no Luck.
So I thought I would give JSB Roofing A try.
Well all I can say I am glad I Did.
They fixed this problem a good few months ago, I still have the habit of checking the area where the Leak was.
And all I can say everything is ok.
They also fitted Eaves on the end of my roof and done an excellent Job.
I highly recommend JSB Roofing.
