First, I commend you for "doing the right thing", a complete re-roof ! It is the only way to know if there is damage to the roof deck and/or the supports. Any flexible roof covering has a life of about 10 years. UV (sunlight) is the enemy. Biannual washing and treatment with a UV protecting will help extend the life.
EPDM or TPO are the only realistic options. TPO comes in different grades/thicknesses. TPO does require some special tools to weld the TPO.
Please explain welding. There is NO welding on EPDM or TPO roofs. Doug
