In order to prevent leaks inside your hope, we do recommend installing metal flashing or copper flashing into the wall and seal properly. Sometimes when installations take place, roofers will commonly leave the wall unsecured and will only watertight on the base. It's important to watertight at least 6" from the wall to the base where it meets the roof.
In order to extend the life of your gutters, we recommend calling us at least twice a year. Another method, specially helpful during fall, is to install gutter covers to prevent any leaves or additional environmental factors from clogging your gutter/ downspout.
