Slate Roof Repairs and Slate Roofing in Terenure
A slate lying in the garden or a gap visible from the street is a prompt to find out why it came loose, not only to replace it. Emerald Isle Roofers Dublin repairs and installs slate roofs for Terenure properties from our business base in Blanchardstown, working with natural slate and fibre-cement slate.
If a slate has fallen, keep people away from the area below that part of the roof. Do not climb up to look, and do not go into an unboarded attic to search for the leak; a qualified assessment can establish what has happened.
Materials and work covered
Natural slate and fibre-cement slate look similar from the ground but differ in thickness, weight, sizes and fixing method. Repairs use slates compatible in size, thickness and appearance with those on the roof, and replacement coverings are selected for the roof's pitch, exposure and structure.
Work can include replacing slipped or broken slates, refixing, ridge and hip repairs, verge details and the junctions with chimneys, walls and valleys. Flashing or valley work is listed separately where it is needed.
Why slates slip and break
A single slipped slate often means its fixing has failed, whether a corroded nail, a perished fixing hole or damage from impact. Several slipped slates across a slope suggest the fixings are failing generally, which changes the conversation from repair towards wider work.
Cracked slates can result from impact, frost or foot traffic on the roof. The assessment looks at the pattern, because the cause decides whether replacing the visible slates will last.
For more on what causes slipped and broken units, read slipped slates and broken roof tiles.
Replacing individual slates properly
A replacement slate should match the existing in size and thickness so it sits correctly in the courses. It must be securely fixed using a method suited to the slate and the position on the roof, so that the repair holds rather than slipping again.
Natural and fibre-cement slates should not be mixed casually, because they differ in thickness and appearance. Where matching slates cannot be sourced, the options are explained before work is agreed.
Reusing slates and taking them from elsewhere on the roof
Sound salvaged slates from the same roof are sometimes the best match for a prominent repair. Taking slates from a less visible slope is only acceptable where that donor area is properly re-covered with suitable slates, and only with your agreement beforehand.
A gap must never be left, or filled with an unsuitable material, to finish a repair elsewhere. The quotation states whether any slates are being relocated and how the donor area will be made good.
Ridges, hips, verges and junctions
Ridge and hip pieces may be bedded in mortar or fixed using a dry system. Where mortar is used, its mix is chosen for the existing roof and materials on assessment rather than applied as a standard recipe. Loose ridges are re-fixed or re-bedded as part of an agreed scope.
Many slate roof leaks start at junctions rather than in the open slope: chimney abutments, walls, valleys and roof windows. Those details are checked with the slating so a repair is not made in the wrong place.
Where the chimney junction is involved, see chimney repairs in Terenure.
When repair gives way to re-slating
Widespread slipping, fixings failing across slopes, battens or underlay in poor condition, and repeated repairs are signs that re-slating may be justified. A sound slate roof with a few failures is a repair, regardless of age.
If the roof is stripped, any concealed problem such as decayed battens or timber is shown to you, described and priced, and proceeds only once you authorise it.
If a full replacement is being considered, see new roofs and re-roofing in Terenure.
Slate roof enquiries from Terenure
We serve Terenure from Blanchardstown. Tell us which slope or area is affected, whether slates have fallen or are visibly out of line, whether water is showing inside and anything you know about previous repairs. Photographs from the ground are useful but never needed.
The quotation names the slate to be used, the number of areas involved, how fixings, ridges and junctions are treated, access arrangements, and anything that depends on what is found.
Frequently asked questions
Can a single slipped slate be fixed?
Usually, if the surrounding slates and fixings are sound. The assessment checks why it slipped so the repair is not repeated elsewhere.
Is fibre-cement slate the same as natural slate?
No. They differ in weight, thickness, sizes and fixing. Repairs use slates compatible with what is already on the roof.
Can you use slates from another part of my roof?
Only with your approval, and only where the area they come from is properly re-covered with suitable slates.
Does an old slate roof need replacing?
Not on age alone. Widespread fixing failure or repeated repairs may justify re-slating; a few failures normally do not.
Should I check the attic for the leak myself?
Do not enter an unboarded or unsafe attic. Contain drips indoors only where there is no electrical or ceiling hazard, keep clear of sagging or swollen ceilings, and leave the investigation to a professional assessment.
