Smarter tools for every stage of real estate.
Roof & Ratio is a real estate tools and resources brand built to make important property decisions easier to understand, organize, and act on.
We started with practical investor tools designed to help buyers run the numbers before making an offer. As the library grows, Roof & Ratio is being built to support the full real estate lifecycle — buying, investing, renovating, managing, owning, relocating, and selling.
What Roof & Ratio is built around
- Investor Tools — deal analysis, cash flow, returns, maximum-offer decisions, comps, and relocation planning.
- Contractor & Remodeler Tools — estimating, job profitability, scope, change orders, bids, and project tracking.
- Homeowner Tools — renovation planning, maintenance, repair decisions, budgets, and contractor comparisons.
- More real estate resources to come — including landlord, property-management, agent, buying, selling, and relocation tools.
Our approach
Roof & Ratio products are designed to be practical, easy to use, and grounded in real-world decisions. We favor clear numbers, plain-English explanations, and tools people can actually use in the field — not complicated templates that require special software or advanced training.
Roof & Ratio by Marchelle was created to turn hands-on real estate experience into useful tools for people making property decisions every day.
