Minor repairs are possible if your roof is under 15 years old. You should inspect your roof if it was installed more than 15 years ago. The likelihood of needing to re-roof your roof increases as the roofing materials age. Remember that a roof that is relatively new may have serious issues or need to be replaced because of poor installation. More info here http://maps.google.dk/url?sa=t&url=https://toasteroid.com/
