About a year ago i had a metal roof installed. I have a cape with a decent pitched roof. It works good as far as winter goes, snow slides off very nicely. However, during rain without any gutters in the front of the house it is causing havic. I have some sections on the rear of the house with some older very heavy duty aluminum gutters which can stand up to the abuse of snow and ice. Looking at the gutters at lowes, i can only imagine they would last about a month on the house. should i really spend the money and install these cheap feeling things?
