Roof Verges: Repoint or plastic

I have a modern 4 bed detached house with two gable ends and two other verges over windows. I recently lost a chunk of mortar/cement out of a small section and am trying to decide whether to have it all checked and re-pointed or go for plastic dry verges. Any thoughts on price for each and if repointing what is the best mix for the job?

I am planning to re-roof my garage using 2mm torch-on felt. The garage roof is about 19 feet long and only has a shallow gradient. Do I need to fit an underlay?

does a new roof require building permission or approval

Lead valleys cracked and allowing water to leak in roof, what are my options to fix ?

roof tiles are old and I want to avoid having to remove tiles or change roof.
thank you

Sandy mortar!

My builder has repointed repointed some of the barn roof tiles on the lower addition of my house. I am concerned that the mortar mix that he has used is very weak, as it has cracked and breaks easily. You can also crumble it away with your fingers as it appears to be very sandy. The builder has stated that he used a 1:4 mix as any stronger would crack the tiles. He's been back around but says it is fine, but i'm still concerned. Any advice please.

Felt under roof tiles has split - what are the options?

Hi all. The felt on my roof under the tiles has split and perished. Is there any other answer then taking all the tiles off to replace it. Is there any other solution. Thanks....

Many thanks for all your input.. It's not a cheap job then coz it's the hole roof. Once again thank you all.

We had a velux window installed 3 years ago and its had constant leaks. Is it best to replace the window or is it possible to ever fix a leak?

Thanks for your replies - very helpful! We've had the builder back 2 times but he's failed to fix the leak and he's very difficult to get hold of.
It tends to leak during really heavy rain and the builder said that leaves in the gutter can cause a leak during heavy rain. Is this true? Gutter overflowing?(We do have a lot of tall trees, leaves and pine needles here).

I have had a re-roof and it is leaking everywhere, what can I do?

I had a re-roof and have had problems constantly along the way. Firstly they didn't do the whole roof, they fell short by about 2-3 feet. They then came back and just nailed tiles on top of the old slate which luckily my neighbour noticed and flagged it up to me. So then they came back and took up that bit and put new felt down and put the tiles back on. I then noticed they had missed the same bit out on the front, but behind the chimney so it wasn't clear to see unless you were a fair distance from the house, which was causing it to leak. I also had a waterfall coming off the front of my house due to the flashing not pointing to the gutter. So they came back for a 3rd time and apparently fixed it.

I still have water leaking into both the front and rear bedrooms and I am having no response from the builder. It is just getting worse and worse every day. One of the rooms was only plastered in July so it is becoming a waste of money the more it leaks.

I was hoping someone would be able to give me some advice on what I can do? I presume my only option is to get another contractor in to fix the problems and attempt to recover the money I have already paid through small claims court? Am I entitled to try and claim for the damages caused by the leaks which have only come about after they "fitted a new roof".

Also, can anyone offer any advice on how to get a decent roofer. I have used this site to obtain two roofers, the first one came and performed a repair then told me I needed a new roof and then the second one did the worst job possible (they both had 100% positive feedback).

Thanks for any responses.

How best do I convert a flat roof into a roof garden - i do need a new flat roof

My flat roof is leaking and it needs replacing but i do want to convert the area into a roof garden. I need steps coming down onto the roof from a higher floor and I would assume that these would need to be fixed to the roof/floor. So what type of flat roof should I go for and then should it be decked to make it harder wearing? help would be greatly appreciated
