Roof felt replacement

lamotu

Hi, my roof has 40 year old felt with holes in places. To replace the felt, means removing the tiles; or so I am told. This is not that much cheaper than replacing the entire roof - about 8K.

Is there any way to replace the felt, without removing the old tiles?

Thanks for your advice.

Obviously to replace the felt the tiles will have to come off but have you considered having the roof spray insulated. The foam insulation is sprayed between the joists and you roof is immediately draft proof and very thermally efficient._snip_I dont know anything about this company but the ad will give you an idea of what I mean, Also you could explore if there are any grants available if you go the insulation route.

You can't replace felt without taking tiles off but costs should be nowhere near a new roof, 8k is very expensive for just a re felt using existing tiles and 8k is cheap for a re roof, all depending on size and existing roof construction of course. Just as a guide a 3 bed semi is typically around 3k to re felt, last one was 3200 but had small extension outback to do as well. Breathable felt, vents etc etc.

Spray foam insulation is in no way an alternative to replacing roof felt. They do two completely different jobs.

You can't replace the felt without removing the tiles.

Thanks all. Just curious, with a re-felt, would you need a hoist, and scaffolding, or can you re-felt as you go. The labour cost of stripping all the tiles is driving up the cost.

Are you re using the old tiles? How big is the roof?

If your using old tiles you should just need scaffolding. Rightly or wrongly this is what we do, strip bottom 6 or 7 rows of tiles and stack on scaffolding, felt that area, move onto next 6 odd rows stacking below us onto new felt and batten as we go and when felted start from below and work up. Two advantages is you don't need to take all the tiles down and back up again and also if you get heavy rain we never have more than a few rows off at a time

In order to do this you must scaffold the whole house. Some guys tell you you don't need to but you do, no choice as working at height is a big health and safety issue. I find in these jobs the scaffolding can be the most expensive part of the job. Then you remove the tiles and you fit new felt and battens. Also when you open the roof you may find the odd bit of rotten timber around eaves, gables and chimneys, this will have to be replaced if it's present but it's never really a major issue.

Planning to reuse the tiles. Small issue, as may have to source some (due to breakage) and the tile is old. If not a big cost difference, would replace all tiles, but seems like it would be too expensive.

If anyone knows of a good roofer in Galway area, could they pm me?

Thanks

When carrying out a job like this if we need to replace a few tiles that break we regularly find them on donedeal.

Wouldn't be any need for new to be honest, it would be more labour as well as the price of new tiles. Not sure about Galway but salvage yards usually have replacement tiles of most types and some tiles are still available new as well, the names are stamped into the back.

Thanks all. Appreciate the advice.
