Matthew came within 2 or 3 days of my contacting him. He obligingly fitted my job in-between his other jobs. Matthew replaced 50 tiles with the correct coloured ones, which match the existing ones perfectly. He worked fast, efficiently, safely and carefully. He did not set foot on my roof tiles (to avoid breaking any tiles); Matthew temporarily removed tiles so that he could walk on the tiling battens. This is best practice used by good roofers. Perfect job, completed in just 40 minutes. Payment requested was very reasonable indeed. Matthew and his colleague were polite and very friendly and cooperative. I am also grateful to Skyline Roofing of Hillingdon for recommending to me: Matthew Otway, Diamond Roofing Specialist.

Having been previously let down by two roofers, it was my lucky day when I saw a 'Diamond Roofing Specialist' van whilst out shopping with my wife. On request I wasgiven a business card by Matt Otway.


Matt duly came and gave me an estimate for a leaking flat roof over my garage, which I accepted, to remove all existing felt and renew. This work was carried out by his team in a very professional manner and they not only did an excellent job,

but were also very polite. All old materials were taken away and everywhere left clean and tidy.


Everything Matt said, the times he would come, phone and start the job, he did! Needless to say I would not hesitate in recommending them to anyone. Many thanks to Matt and the Boys.

Diamond Roofing came to fix my roof during the awful storms this past Winter. I have never experienced such polite, professional, diligent & quality service in all my life. It was a much longer job than anticipated, yet there wasn't one grumble- they worked incredibly hard to get it all done before losing the daylight & looked after themselves all day... we didn't even know they were there! And the price gave us both something to smile about. Beyond pleased & I would recommend them to anyone in a heartbeat.

Just a little email to say a big thank you for the work you have carried out this week on my Mum’s best friend’s roof and chimney.   You and your team are absolutely amazing and such a pleasure to deal with.   The work was all carried out in a professional, timely and efficient manner - 'J' who is 90 was so anxious about having the work completed, but you made her feel totally at ease and were so kind towards her - thank you so much.   We are all so pleased with the roof and chimney - the work all looks fantastic and it is such a relief to know that the ridge tiles are all securely in place and that the chimney is sound.   Thank you too for repairing Joan’s garage roof and for sealing my Mum’s conservatory roof.  The price you charged us was a very fair, reasonable price, Matt and thank you so much for keeping to the agreed date to do the work - and for actually completely the work slightly earlier than you thought.


The work was all carried out in a very tidy manner and the whole area around the bungalow and in the garage was left very clean and tidy - thank you.

We always appreciate the work you have done for us and, of course, have no hesitation recommending you and your team to anyone.    


We will certainly be giving you a call next time we need any roof repairs.  In the meantime, stay safe and well, Matt.   Many thanks to you and your great team,

Matt & co did a great job on new flat roof, repairs to main roof, new fascia and guttering. Was punctual, clean and tidy. Would definitely recommend.

Matt gave me a good price to strip and fit a new garage roof. He took away all rubbish from the site leaving it clean and tidy and without me having to worry about its disposal, and the new roof looks great!
