Roof coating and sealing protects your roof from weather damage and extends its lifespan—and you can do it yourself for just materials costs. Use NailIt to estimate exactly what you'll spend on sealant, primer, brushes, and safety gear before you start. No labor or contractor markups—only what you buy.
Estimated DIY materials cost for total materials for typical residential roof (1,000–1,500 sq ft) — you supply the labor. Prices vary by region and brand.
Across the full range this works out to $0.27–$1.20 per sq ft, depending on material grade and how much waste you plan for.
Here is the arithmetic, so you can redo it with your own numbers: a typical project here is 1000–1500 sq ft and runs $400–$1,200 in materials. Divide the middle of that cost range by the middle of the area range ($750 ÷ 1250 sq ft) and you get $0.60 per sq ft. Measure your own space, multiply, and you have your materials budget.
Materials only — labour is not included. See what a contractor charges below.
A handy DIYer can usually take this on; if it needs permits or systems you are unsure about, get a pro quote first. The pro figure is a rough rule of thumb (labor on jobs like this often runs 1–2.5× the materials) — always get real quotes. It is not a NailIt estimate.
NailIt estimates materials only, so here is the honest version of the labour question rather than a number we cannot stand behind. Installed, this job commonly lands somewhere around $800–$4,200 — that is the materials range above with labour applied at the rough 1–2.5× multiplier trades typically work to on jobs like this. It is a sanity check for reading a quote, not a NailIt estimate and not a substitute for a real one.
What actually moves that number: your region and local labour rates, access and prep work, whether a permit and inspection are involved, disposal of the old material, and how much the crew has to work around your schedule. For this project most homeowners are better off getting quotes — see the gauge above. Always collect three written quotes from licensed, insured contractors and compare what each one includes — how we handle pricing.

Only materials you buy: roof coating, primer, sealant, brushes, rollers, safety gear, and supplies. Labor and contractor costs are not included—this is pure DIY material cost.
Most acrylic and elastomeric roof coatings cover 250–400 sq ft per gallon. A typical 5-gallon bucket covers roughly 1,250–2,000 sq ft. Measure your roof and adjust quantities in NailIt accordingly.
Yes, in most cases. Primer improves adhesion and sealing performance, especially on weathered or bare roofs. Budget 5–10% of your coating cost for primer—NailIt factors this into your estimate.
