Flat Roofing Cardiff EPDM GRP and Felt Explained

By @lukasigtp377

❦
Look along almost any street in Cardiff and you will spot flat roofs on rear extensions, dormers and garages. They are practical and popular, but they also take a pounding from the rain and wind that roll in off the Atlantic, and heavy rain soon finds any weak point. Redland Roofing Cardiff is an independent, family-run roofing business that has served Cardiff and South East Wales for over 30 years, and flat roof repair and replacement is a big part of what we do from our base in Rumney, east Cardiff. Three materials cover most of the flat roofs we work on. EPDM rubber is a speciality of ours, and as general guidance an EPDM roof lasts 25 to 30 years or more. GRP fibreglass gives a hard, durable finish and typically lasts 30 to 40 years. Traditional felt is still widely used, though a felt flat roof usually lasts around 10 to 15 years. Each has its place, and the right choice depends on the size of the roof, how it is used and what sits underneath it. As experienced roofers in Cardiff, we will explain the options honestly and recommend what genuinely suits your property, rather than whatever is easiest to sell. Flat roofs tend to fail in a few predictable ways. Cracked surfaces, opened joints, blocked gutters and worn coverings are the usual causes of leaks, and they often show up as a damp patch on an extension ceiling or water in the garage. Where a repair will do, we will repair it. Where the covering has reached the end of its life, replacement with EPDM or GRP is often the longer lasting answer. We work on rear extensions behind the terraces of Roath, Plasnewydd and Grangetown, dormers in Heath and Llanishen, newer homes around Cardiff Bay and garages from Danescourt and Radyr to Pentwyn and Llanedeyrn.

It depends on the damage, the roof type and access. As a rough guide, Redland Roofing Cardiff price minor jobs such as replacing a few broken tiles from around £150 to £300, while storm damage or new flashing usually runs from £300 to £800 or more. Every quote is free and written down before any work starts, so there are no surprises. How can I tell a dodgy roofer from a good one? Be wary of anyone who knocks on the door uninvited, pushes for cash up front or claims the whole roof needs replacing without showing you why. A reputable Cardiff roofer will give a written quote, explain the guarantee, confirm they are insured and show you photos of the problem. Redland Roofing Cardiff do all of this as standard on every job. Who are some reputable roofers in Cardiff? Look for an established local firm with a long track record and plenty of genuine reviews. Redland Roofing Cardiff are an independent, family-run business that has served Cardiff and South East Wales for over 30 years and holds a 4.8-star rating from more than 200 Google reviews. They are based at 1 Trecinon Road in Rumney and cover the whole city. Does my roofer have to give me a guarantee in writing? You should always ask for it. Redland Roofing Cardiff set out the guarantee on labour in every written quote, and materials carry manufacturer warranties where applicable. If anything isn't right after the job, the team come back and put it right. How do I know if a roofer is any good? Check recent reviews, ask how long they have been trading and see whether they explain the problem clearly before quoting. Redland Roofing Cardiff customers often mention being shown photos of the issue, quick next-day repairs and tidy, polite teams. A roofer who recommends a repair rather than an unnecessary replacement is usually a good sign. What questions should I ask my roofer before work starts? Ask what exactly is wrong and how they know, what the written quote includes, how long the job will take, whether they are insured and what guarantee you get. For a full re-roof, ask how the house will be kept dry overnight. Redland Roofing Cardiff leave roofs watertight at the end of every working day and give a clear timeline before starting. How long does a roof last in Wales? Welsh rain, coastal winds and freeze-thaw cycles all shorten roof life. A well-installed concrete or clay tile roof can last 40 to 60 years with maintenance, and good slate can outlast the building. Felt flat roofs tend to last 10 to 15 years, while EPDM rubber, which Redland Roofing Cardiff specialise in, can last 25 to 30 years or more. What usually causes a roof to leak? The most common culprits on Cardiff homes are slipped or missing tiles, cracked flashing around chimneys, blocked gutters, worn valleys and failed lead joints. On extensions and garages, flat roofs often leak where the surface has cracked or a joint has opened. Redland Roofing Cardiff trace the source first so you only pay to fix the real problem. Do I need planning permission to replace my roof in Cardiff? A like-for-like replacement on a standard house usually falls under permitted development. In conservation areas such as Pontcanna, parts of Roath and Llandaff, on listed buildings, or if you are changing materials, you may need consent from Cardiff Council. Redland Roofing Cardiff can advise on this during the free assessment. How quickly can a roofer come out in an emergency? Redland Roofing Cardiff run a 24/7 emergency service across Cardiff and South East Wales for storm damage and sudden leaks. The aim is to get someone to you as quickly as possible and make the roof watertight. Call 07884 013048 at any time of day or night. How long does a full roof replacement take? A standard terraced or semi-detached house in Cardiff typically takes 2 to 4 days, weather permitting. Larger detached homes, such as many in Cyncoed and Lisvane, or roofs with complex shapes usually take 4 to 7 days. Redland Roofing Cardiff confirm the timeline in writing before work begins.
