I am hoping to find some assistance with a re-roofing question. My Mother owns a contemporary-style home with a 3:12 pitch roof that currently has a slag/tar and white gravel roof. The existing roof is 30 years+ old and it is replacement time. 1 major leak and a substantial amount of green moss.
Finding the right solution for this project has been difficult. I have various contractors who recommended rolled/torch-down products, shingles and I have found 1 contractor who recommends shingles but will do a slag/tar and white gravel replacement.
Mother does not appreciate the look of the rolled products. She laments that from the street her home will look like a tar paper shack. I am intrigued by the shingles, but have read various things about the success of shingles on low-sloped roofs. I am told the slag/tar and white gravel is an old-fashioned way of roofing.
Help would be appreciated? Shingles or slag/tar and white gravel? How do I make this a good roof? We all know how a disappointed Mother can be.
