About Gutter Guard Lab
Gutter Guard Lab is an independent independent reference site for homeowners evaluating gutter guard selection, installation costs, and gutter maintenance. We build tools and calculators and guides that answer the questions that actually matter: which gutter guard type fits your roof and debris, how to size gutters for your home, and a real cost range that is not pulled from thin air.
How our numbers work
Every calculator runs on standard building formulas and aggregated cost data, the same figures used by estimators and published in manufacturer spec sheets. Gutter sizing follows roof area, pitch, and regional rainfall zones (per IRC and local codes). Guard recommendations are based on debris type, roof pitch, climate, and budget, matched to real product specs. All prices are shown as ranges with an “as of” date because labor rates and materials shift by season and ZIP code. We never publish a made‑up statistic.
What we are not
We are not a contractor, home services marketplace, or engineering service. Our tools and recommendations are planning estimates, not installation instructions. For anything structural, code‑related, or safety‑critical, confirm with a local professional before you buy or install.
