Roofing quotes feedback request for rented 2-bedroom property

Hi all

The roof of the 2 bedroom mid-terrace I rent out in Outer London is leaking and I have obtained quotes from three Checkatrade companies for repair work. However I am not technically well versed in roofing nomenclature so I am not sure of how different the work being offered is, or which quote is the best in terms of value for money. Photos of the damage are linked and any feedback would be greatly appreciated.

Thanks for looking!

I have sorted many roofs . You cannot tell from photos what will be best . Scaffolding is always needed. Just because they are on check a trade means nothing. Every builder will have a different idea of what needs doing… Get a recomendation from a house owner near to your property, who has had roof work done

for comparison have you had a quote for a complete new roof?

Hi Colin3

Thank you for the comments - they were very useful. I didn’t think of asking a quote for a new roof - do you have a rough idea how much that might cost for a semi-detached 2 bedroom property?

Sadly I don’t know any of the house owners in the area or even anyone who has had their room done where I live either.

I’ve never used Checkatrade, so can’t comment on that specifically but some of those types of sites are just glorified advertising services.

I usually use our local council trusted trader site because the local council are not in it to make a profit like a commercial site.

Depends on the roofer and the work required as to whether scaffolding is needed. I’ve just had a roofer repoint my chimney and he’s also re-setting the ridge tiles when weather permits and he’s not using scaffolding.

Thank you for the information about the local council trusted trader site - I wasn’t aware of that before.
Luckily it turns out that my local council runs that scheme so i will definitely get at least one quote from the traders there.

IF a roofer is judged by trading standards to be at risk by not using scafold and is doing a job in an unsafe, manner the fines are in the 1000 s even tho he is risking his own life

Interesting to know. This is literally the first major repair I have had to have done for either my home or my rented property so I am picking up a lot of helpful tips.

Thanks again for the insights - it is really helpful for us newbies.

Roof costs depends on access,. tile used, amount of lead etc remember a concrete tie roof has a life of about 40 years. so how long ago was that roof done.? Sometimes its better to whip it all off and start again

I got the house 7ish years ago and it hasn’t needed any roof-work till now. Sadly that is the extent of my knowledge.

Are those pics of your roof? you seem to be showing 2 different types of tile Or is that part of next door?

I have never been up to the roof but I believe that some of the photos may be pictures of the palisade at the edge of my house’s roof as I was told that there were leaks from there.

I have had terrible people on the past from Check-a-trade and the council’s approved traders list.

There is an app called Next Door which is very active in my area but obviously I don’t know about your area.

It is used a lot to get recommendations from neighbours.


Sorry to hear about that Mr. T.

I haven’t joined the local Next Door app but that might be useful to crowdsource finding good tradesmen - thanks for the suggestion.

I would look for houses with a new, clean, recent roof and ask who did it, and are they happy with the result… I worked for 50 years in peoples homes, never advertised, all reccomendations, lots of loft conversions and roofing. Never joined any organisation. always in work .Made a good living… ask around !!

Most of the people on these websites are not that reputable . I wrote to mybuilder when we had failed interest ( people inflating prices, gypsy etc). The last chap off checkatrade admitted to using red diesel and did a horrific job ( they also rarely publish negative reviews unless you meticulously collate evidence as it is not in their interest to publish negative reviews. Check a trade registering costs circa £1k per annum for a workman. They make a lot of money with a registered workmen). Rated people is no better. The other issue is people not in the know don’t know if they are being ripped off and will write a review because the workman was nice. Does not mean they did a good job.
Best to ask someone ( do you have regular workmen you use? they always know someone )
Recommended is usually the best way


Check out a roof with binoculars

Do you mean they are not overlapping in the way slates do sideways that is?

Yes I was a bit worried about the lack of knowledge so tried to get a few quotes. I will try to see if my neighbors know anyone they can recommend.


Actually I think I have an old pair of binoculars somewhere so I can take that next time I go around the house.
