Most Ranelagh roofs are old slate with newer things cut into them: a dormer from an attic conversion, a roof window, an extension at the back. The leak is usually at the join between old and new, or in lead that has been there as long as the house. Jordan surveys the whole roof for free, including what the parapet hides, and gives you a written price for the repair.
The slate itself is often good for years yet. What fails is the flashing round what was added, the lead that was there already, and the nails holding the slates on.

A dormer or a roof window put into a slate roof leaks where its flashing meets the slate, not through the window itself. The lead round the cheeks and the head of a dormer, or the kit flashing round a roof window, is renewed and dressed into the slate, and the slates around it are refixed.

On a parapet-fronted house the front gutter is a lead trough you cannot see from the street, and the valley with next door is lead too. When either blocks or splits, the water comes into the top floor. It is cleared, the lead checked along its length, and the bad sections relined in new lead.

The iron nails under original slate rust away long before the slate does, so sound slates slide out one after another. They are refixed with hooks or tingles and broken ones matched in natural slate. Where the felt underneath has gone as well, that slope is stripped and re-slated, keeping as much of your own slate as is worth keeping.

Jordan looks at the whole roof, from above with a drone where it helps, so the price is based on what is actually there.
A written price before any work starts. If hidden damage turns up, Jordan shows you and prices it before going further.
Fully qualified roofers, proper materials, and the site left clean when the job is done.
The price is settled on the survey, not on the phone, because what is wrong with a dormer flashing or a parapet gutter cannot be seen from the ground and cannot be guessed from a description. Jordan surveys the roof, including the slopes a parapet hides, and gives you one written price for what he finds. If the slates come off and the timber under them is rotten, he shows you and prices that before anything else is done.




Delta Roofing is family-run and based in Kimmage, Dublin 12, on the far side of Rathmines from Ranelagh. It has been in business for over 20 years. The photos on this page are Jordan's own jobs, with no customer's house named: a roof window going into new slate, a new lead valley with the slates going back, and a slated extension roof with two roof windows.
One customer's Google review says what the end of a job looks like: "Jordan sent a video of the before and after." Ring the office Monday to Friday, 9:00 to 18:30, or the mobile, 087 645 9553, at any hour if water is coming in.

Storm damage, a slipped slate, a leak over the bed. The mobile is answered 24 hours, so ring it first.
Emergency roof repairs, what to expectWhat people ask when a dormer, a window or a parapet is the problem.
Nearly always a repair. The dormer is sound; its flashing has lifted or was never dressed into the slate properly. The lead round the cheeks and the head is renewed and the slates refixed around it. The survey confirms it before anything is priced.
Because a parapet gutter or a valley is overflowing rather than leaking all the time. Normal rain gets away; a downpour backs up behind the blockage or the split and comes in under the slates. Clearing it is step one, and the lead is checked while it is clear.
Where the old slate is sound it is lifted, kept and relaid, and the gaps made up in matching natural slate. The survey shows how much of your own slate is worth keeping.
Yes. The slopes and the gutter behind the parapet are looked at from above, and the attic shows the felt and the timbers from underneath. A scaffold is only in the price when the repair needs one.
Not usually. The window is flashed into the existing slate and only the slates cut around the opening are new. If that slope is losing slates on its old nails, the survey will say so, because fitting a window into failing slate is work done twice.
Whoever is responsible for the building, usually the owner or the management company. Jordan surveys once and sends the written price to them, and the work is booked with whoever is paying.
A free survey of the whole roof, a written price from Jordan, and fully qualified roofers to do the lead and the slate.
