In our opinion, asphalt shortages and rising production costs left some shingle manufacturers producing shingles that weren’t all they were “curled up” to be! Many of the roofs being replaced today are less than 15 years old, leaving homeowners frustrated and confused about their next roofing choice. Therefore, we have researched high quality asphalt roofing products, buying only from reputable manufacturers at very competitive prices! Make your next roof your last roof with help from Johnson’s!
