House 18 years old and original shingles were curled and starting to expose the paper underneath the granules. Contaced Goreski's and they were extremely courtious over the phone and arranged a day and time for an estimate to be done. man came to house, provided me several options of shingles that could be used along with detailed pricing for each type. Went with a fiberglass type shingle with a 30 year warranty. Job was done and loks great. NO nails or scraps left behind anywhere.
