Internal Roof Spraying

[Mamf74]

Hi, am asking advice on behalf of my DM. She started to take her pension in January but it still working so is taking advantage of this by sorting out all of the jobs on the house before she goes down to pension alone.

She is considering having the inside of her roof sprayed & sealed; she sees the outlay (approx 3k) as being less than the cost of a new roof and should see out her time in the property. She is in a maisonette but her roof space is equivalent of a 3 bed semi.

So, is this a good idea or is it the modern equivalent of stone cladding or pebble dashing? I must admit to having reservations as I understood that roof spaces need ventilation but she seems convinced.

The second thing is that she's had 2 companies to quote, however one seems to only want to rubbish the other and is quite aggressive about her signing. Does anyone have recommendations of good companies that offer this (or, obviously, people to avoid)?

Thanks for any advice!

I've only heard bad things about this - you are right that the roof needs to breathe. There is also an option to have the tiles themselves sprayed but I don't know anything about this, just fyi. Best to google, then you can present your Mum with some 'expert' opinions. I would also be very suspicious of any company that uses aggressive sales tactics, they certainly wouldn't get my business. Is the roof already in need of repair then? A straightforward roofer might be a better bet and could do moss removal/repointing/tile replacement etc. What about soffit/fascia repairs too, that way you would also (if you pick a decent company) get any rotten roofing timber ends repaired. Good luck!

eeeeeek! no!

apart from the people who sell this treatment, no-one has a good word to say for it. It traps moisture against the battens, causing them to rot, and it sticks so tightly to the tiles that they can't be easily removed and replaced when repairs are necessary. The whole roof has to be stripped off, which takes much longer, so costs much more, than usual, because it's all glued together.

the people who sell the treatment are naturally anxious to get their hands on her money.

Do a websearch on Roof Spraying and see what turns up.
