About ShingleScience
Your roof is the single most expensive component of your home's exterior — and most people don't think about it until there's a stain on the ceiling. ShingleScience was founded by a contractor who got tired of seeing homeowners taken advantage of by storm-chasers and high-pressure sales tactics. We provide the honest, straightforward information you need to make smart roofing decisions.
Our Mission
A new roof can cost $10,000 to $30,000, and the wrong decision can cost you even more in water damage, mold remediation, and premature replacement. We want every homeowner to have the same knowledge a good contractor would give you — what to look for, what questions to ask, and how to tell the difference between a solid bid and a sales pitch.
