Some useful tips and considerations when hiring a contractor for a new roof replacement

Obtaining Quotes
1. Look for accredited contractors. There are good quality contractors out there that are not accredited, but the only way to be sure you get what you’re looking for is to use one that is.The NFRC is the best accreditation in the UK roofing industry. Members are vetted on application and are also randomly spot checked on workmanship and company practice.

2. Consider a ‘Competent Roofer’ member. The competent roofer scheme is another accreditation of sorts. Members are screened, and once membership is obtained, they can self certify new roof coverings (provided they are like for like coverings). This eliminates the need to call in the local council Building Control, which would incur additional charges. A completion certificate is provided when the project is finished.

3. Be sure that the contractors are quoting on the same specification. Some contractors may include scaffolding, some may not. Also, don’t be afraid to ask contractors which manufacturers they are planning to use for the materials.

Covering Types

When choosing a new covering, you may consider a few factors such as:

  • Current covering weight
  • Neighbouring property coverings (for matching in)
  • Conservation areas
  • Price

Increasing the weight of your covering will likely incur some structural reinforcement. It will also mean that the council Building Control will need to be involved… which means more cost.

Some people like to keep the covering ‘in keeping’ with neighbouring properties. This is a preference, and unless it is a conservation area, there is no obligation to follow this rule.

Here is a rough price guide on some common covering types:

Synthetic Slates £££

Insulation

At the time of writing this guide the recommended minimum insulation requirements are 270mm in rock wool type insulation, or 100mm in foam board insulation. Contractors have to advise that these minimums are met to achieve a completion certificate. You should consider insulation when you are planning your new roof covering.

 

Extras

Guttering, fascias, soffits & chimney caps are not usually included in a new roof estimate.

 

Considerations in Summary

  • Neighbouring Homes – Will a change of covering make your property stand out too much.
  • Area – Choosing a local company will  save money. We operate from London, South London and Surrey. We complete hundreds of projects every year. Particularly in Brixton, Streatham, Norwood, Norbury, Croydon & Clapham, but also in many other parts of London and Surrey.
  • Aesthetics – Are you renewing for aesthetical purposes or purely practical.
  • Structure – are you planning to remove a lighter covering and replace with a heavier covering, which may require some minor structural strengthening. We are Competent Roofer Accredited, meaning we can self- certify on like-for like projects (No building control required!). You still get a pass certificate.
  • Insulation – 270mm is currently the councils required insulation depth (when possible)
  • Building Control – A new roof requires a completion certificate. We are Competent Roofer members, so are able to selfcertify most projects… Which means no additional costs for building control.
  • Colour – There are many choices of colour. We are happy to provide samples to help you choose.
  • Redland tiles colours styles
  • Scaffolding – Our estimates are inclusive of scaffolding.
  • Conservation Regulations – If your property is in a conservation area, you will need to check if your chosen covering is acceptable.
  • Payment – Payment is due on completion
  • Roof Windows – Why not take the opportunity to add one?
