Who Are We?

TW Roof Estimating are based in Glasgow and headed up and run by Tom Walls. Tom has over 39 years experience in the roofing industry, and has been providing pitched roof estimates for over 35 years. He spent 13 years with one of the market leaders Marley Roof Tiles where he gained his qualification in pitched roof estimating with the NFRC (National Federation of Roofing Contractors). Tom has also worked with another market leader, SIG Roofing Supplies, for over 20 years.

In 2014, Tom set up TW Roof Estimating and provided his unique service exclusively to SIG Roofing Supplies. Since then, he has developed and refined the services provided by TW Roof Estimating and we are now the top choice for roofing estimates, providing our specialist service throughout the UK to companies and private individuals alike.

Our industry leading estimating service is based remotely which enables us to provide you an accurate list of materials, no matter where you are in the UK. You can send details of your project by email, post or even hand deliver them to us, and we will do the rest!

We can calculate the quantities required from architect’s drawings, bills of quantities and even from a hand drawn sketch with measurements stated.

Completely independent, TW Roof Estimating will provide you with a comprehensive and easy to understand list of materials which you can then use to get the best prices from different suppliers, safe in the knowledge you are getting the right materials in the correct amounts.

We aim to have the comprehensive list of materials needed for your project with you in 48 - 72 hours, however larger or more complex roofs and sites can take a little longer, but we will let you know if this is the case...
