Factors Affecting the Cost of Replacing a Flat Roof in Sheffield
There are several factors that will affect the total cost of replacing a flat roof in Sheffield, and they include:
- The shape and size of the roof – This will determine how much material needs to be used. All roofing is sold by square metre (m2). For example, a 3m2 porch should cost around £110 to £165 based on current felt installation prices of £35-£45 per m2, although you may need to buy more to cover an awkward shape.
- The type of material: The three most common types of material are felt, EPDM rubber and fibreglass, which range from £35 to £55 per m2.
- Complexity and Access – Installing a flat roof on a modern home is likely to need scaffolding to install safely. The average cost of scaffolding is between £890 and £1,040 per week.
- Removal and disposal costs of the old roof – Your quote may not include the cost of disposing of the material from the old roof. If this is the case, you may need to hire a skip. The cost will be around £220 for skip hire.
- Building regulations state that you need to have insulation on a roof covering an unheated space. The cost of materials is between £7 and £15 per m2, depending on the type of insulation you use.
- Labour rates – Flat roofers in Sheffield charge between £345 and £425 a day.
Investing in a new flat roof can increase your property value and enhance the appearance and efficiency of your property. Upgrading your roof can also help save money on energy bills over time, making it a cost-effective improvement for your home.
Roof Insulation
You only need Insulation on a roof if it is covering a habitable space. Garages and porches aren’t habitable, so they aren’t required. But if you are covering a room in a home extension, then you can choose between a warm or cold roof with a u-value of 0.18 W/m2K.
Including insulation is an important consideration in any roofing project, as it affects energy efficiency and comfort.
A cold flat roof is less expensive. The insulation is placed between the roof joists along with the addition of ventilation so that damp doesn’t appear due to a build-up of moisture and condensation.
A warm flat roof costs more to install. The insulation is placed under the waterproof layer on the roof. It keeps heat trapped indoors more efficiently than a cold roof, so it is often recommended for home extensions.
How Long Does a Flat Roof Replacement Take?
Most flat roofing installations take, on average, between 2 and 3 days to complete. The roof of a home extension could take longer because of the size, so you should allow between 6 and 7 days for the job to be completed.
Weather conditions can delay the start or finish of a flat roof installation. Drying times and labour schedules need dry weather.
Flat Roof Lifespan and When to Replace
Typical Lifespans for flat roofs are:
- Felt: 10 -30 years
- EPDM: 25 -50 years
- Fibreglass (GRP): 20 – 30 years
- Lead: 100 years plus
- Green Roofing: 30 – 50 years
Bad weather can damage your flat roof. If you see water pooling on the roof’s surface or you notice a leak, then check the roof for damage. Cracks and tears in the material are also signs that you may need a roof repair or replacement.
