Most home lenders require a home inspection of the property you want to buy before they will lend you the money. In most cases the home inspector will do a fairly good job. However there are the times when they make critical mistakes when doing the roof inspection. Once you sign the papers for your new home it’s yours and you soon find out about hidden faults that even the home inspector missed. You should always get a second opinion when it comes to your roof.
I have seen times where roofs are in need of almost a complete re-sheet (that’s when the roofs plywood is in need of replacement). And that is a very expensive task and on top of that the roof will have to be replaced because you have to remove it to replace the plywood. What happens is the selling homeowner knows the roof needs to be replaced but doesn’t have the money to do it so he’ll get a roofing contractor to cover up the can of worms (the bad plywood) for little money and “A no warranty AS IS cash deal”. This doesn’t happen a lot to this degree but it happens more than it should. When it comes to your roof you should always take extra precautions it’s not just a part of your investment it protects your whole investment.
After all a house is nothing with out a roof!
