House renovation

We visited again the family of my brother in law last Sunday.We had a little family gathering there.My BIL,asked my husband some suggestions,he wants to renovate his house,there are some repairs to be done and replacement.Some of us even noticed that their roof has to be changed.My husband suggested that in their roof,they should switch to metal roofing for it is more solid and durable compare to his roof now.Metal roof will last very long and it's an energy saving roof too.Since there will be some renovations to do,my husband even volunteer to help them to save some money.Maybe we'll help them when we are done transferring to our new home.
