Flat roof repair near me Harmonstown

Flat roofs tend to fail in familiar ways: felt that blisters and cracks in the sun, laps that open up, rainwater ponding in a dip until it finds a way through, and upstands or edge trims pulling away from the wall. Most of these can be repaired when they are dealt with promptly, and a good repair gives a sound roof plenty more service. We take on flat roofs in Harmonstown (D05), County Dublin, including nearby Edenmore, Killester, Raheny and Artane, from our office in Sandyford, Dublin: call 01 263 5253 for a free written quote.

Felt Roofing Harmonstown

Modern felt roofing is a long way from the single sheet of tarred felt that covered so many older extensions. Current torch-on systems are built up in layers, a base sheet bonded to the deck and a mineral-finished cap sheet on top, for a tough, weather-resistant finish at a sensible cost.

Harmonstown Bitumen Felt Roof Benefits

Felt is the most economical way to cover a flat roof, and it copes well with the occasional foot traffic of gutter cleaning or maintenance. The mineral cap sheet shields the bitumen from sunlight, the layered build gives a second line of defence if the top is damaged, and patch repairs are straightforward.

Rubber Roofing Harmonstown

EPDM is a synthetic rubber membrane laid as a single sheet, so on most domestic roofs there are no joints across the main area for water to work into. It is bonded cold with adhesive, which means no naked flame on site, and it stays flexible through hard frost and summer heat alike.

Harmonstown EPDM Rubber Roof Benefits

One sheet of rubber forms one continuous skin over the roof. EPDM stretches as the building moves rather than cracking in the cold, and because it is cold-bonded it is a sensible choice on timber extensions and dormers sitting close to windows, soffits and cladding.

Fibreglass Roofing Harmonstown

GRP fibreglass is built on site: glass fibre matting is laid over a new deck and wetted out with resin, then sealed with a coloured topcoat. The result is a rigid, joint-free surface with neat preformed trims, well suited to balconies, dormers and any roof you look down on from an upstairs window.

Harmonstown GRP Fibreglass Roof Benefits

Fibreglass cures hard and smooth, so it handles light foot traffic and looks tidy from above. There are no laps or joints to open up over time, it comes in a choice of topcoat colours, and it forms cleanly around rooflights, outlets and awkward corners.

FAQs

FAQs about our flat roofing service

Straight answers to the flat roof questions people in Harmonstown raise most often.

Which flat roof covering is best?

There is no single best option. Felt is the most economical and easy to patch, EPDM rubber goes on as one sheet with no flame, PVC membrane is light and suits larger or commercial roofs, and GRP fibreglass gives a hard, tidy finish for balconies and dormers. We recommend one after seeing the roof, how it is used and your budget.

Can my flat roof be repaired, or does it need replacing?

If the deck underneath is dry and solid and the damage is local, a repair is usually worth doing. If the boards are soft, the covering is brittle across the whole roof, or it has already been patched many times, re-covering is better value. We check the deck before advising either way.

What are Lava 20 and Mariseal?

They are cold, liquid-applied polyurethane waterproofing coatings. Brushed or rolled on, they cure into a flexible, fully bonded skin with no joints, which makes them a good answer for awkward details such as parapet and box gutters, balconies, and roofs crowded with pipes and vents where sheet membranes are hard to seal.

Why does water sit on my flat roof after rain?

A flat roof should never be truly flat. It needs a slight fall so rain runs off to the gutter or outlet. Ponding usually means the deck has sagged, the falls were never built in, or an outlet is blocked.

Do you repair garage roofs?

Yes, garage roofs are regular work for us, as are rear extensions and outbuildings. We can repair the existing covering or strip it back and lay a new deck and membrane, and we will tell you plainly which gives better value for the money you are spending.

Can a flat roof be done in winter?

Some systems depend on the weather. GRP resin and liquid coatings need dry conditions and reasonable temperatures to cure, and EPDM adhesives have similar limits, while torch-on felt is more forgiving. For a leak that cannot wait, we make the roof watertight in almost any weather and complete the permanent work when conditions allow.

Why Choose Us

Why choose Dublin Roofing Company for your Flat Roofs Harmonstown?

A flat roof is only as good as the deck beneath it and the detailing at its edges, and that is where our roofers in Harmonstown put their effort.

Covering Harmonstown

An Office You Can Find, a Phone That Gets Answered

Quotes, bookings and any follow-up are handled from our office on Fern Road in Sandyford, Dublin.

Every System Offered

Felt, rubber, PVC and fibreglass are all part of our work, along with Lava 20 and Mariseal liquid coatings, so you are steered to the right covering rather than the only one a roofer fits.

Decks Checked First

Before re-covering, we test the boards underneath. Soft or rotten decking is replaced, because a new membrane laid over a failing deck simply hides the problem for a while.

Insured, Qualified Roofers

Every flat roof is laid by qualified roofers with full public liability insurance, whether it covers a small garage, a rear kitchen extension or a commercial unit.

Weekend Repairs Too

Leaks rarely pick a convenient moment. Flat roof repairs can be booked for a weekday or a weekend to suit you, with emergency cover around the clock when water is coming through.

Call or send the form with your Eircode and we will arrange a visit, look at the roof and price the work before anything starts.

Professional Flat Roof Repair Harmonstown

Not every flat roof suits a sheet membrane. Where a roof is crowded with pipes, vents and upstands, or a gutter or balcony has awkward shapes, we often use Lava 20 or Mariseal, cold liquid polyurethane coatings that bond directly to the surface and cure into one unbroken layer. On larger commercial roofs, a PVC membrane is often the lighter and quicker solution.

Every repair we carry out in Harmonstown starts with finding the real cause and finishes with the edges, outlets and upstands checked, so the next downpour does not find a new way in. While we are up there, we will also mention anything else we spot, from a blocked outlet to a tired flashing.
