RhinoRoof U20 typically costs about $75-$145 per roll, with an average near $105 for material covering roughly 1,000 square feet. Roof size, retailer, freight, local labor, and whether the underlayment is added during a full roof replacement determine the final price.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| U20 roll | $75 | $105 | $145 | Approx. 1,000 sq ft coverage |
| Material per sq ft | $0.08 | $0.11 | $0.15 | Before waste and delivery |
| Installed underlayment add-on | $0.20/sq ft | $0.35/sq ft | $0.60/sq ft | Incremental labor and materials |
| Typical 2,000-sq-ft roof | $400 | $700 | $1,200 | Installed add-on estimate |
Assumptions: U.S. retail pricing, standard access, approximately 1,000 square feet of labeled coverage per roll, and no tear-off or deck repairs.
RhinoRoof U20 Roll Price and Roof Coverage
At the estimated average of $105, one roll works out to about $0.11 per covered square foot. Actual coverage should be confirmed on the product packaging or retailer listing; laps, cuts, roof geometry, and handling waste mean a roll does not necessarily protect a full 1,000 square feet of roof deck.
For material budgeting, plan on roughly $0.08-$0.15 per square foot before waste, tax, and delivery. A simple roof needing about 2,000 square feet of coverage may use two rolls, while a complex roof may need an additional roll or partial roll allowance. Confirm roll dimensions and stated coverage before ordering.
What U20 Roofing Quotes Include Besides the Roll
A materials-only price and a contractor’s installed price cover different things. The table separates typical U20 material from common job charges; actual contractor estimates may bundle labor and accessories into a broader roof replacement price.
| Quote item | Typical price | What changes it |
|---|---|---|
| RhinoRoof U20 | $0.08-$0.15/sq ft | Retailer, roll price, coverage |
| Labor to install | $0.10-$0.35/sq ft | Pitch, access, crew rates |
| Cap fasteners or approved attachment | $0.02-$0.08/sq ft | Deck type and fastening method |
| Delivery or small-order charge | $15-$100 per order | Distance and order size |
| Deck repair, if needed | $3-$8/sq ft | Damaged sheathing and repair scope |
Ask whether the quote lists U20 by itself or includes installation, fasteners, delivery, and waste. Labor may not appear as a separate charge when the underlayment is installed as part of a complete roofing contract.
How Roof Size, Pitch, and Waste Change the U20 Budget
Roof area, rather than the home’s interior floor area, determines how much underlayment is needed. A 1,500-square-foot roof at $0.08-$0.15 per square foot has a material-only baseline of $120-$225; a 3,000-square-foot roof has a baseline of $240-$450. These calculations exclude extra rolls for waste.
Allow more material when the roof has hips, valleys, dormers, or many short sections. A straightforward roof may need around 5%-10% extra, while complicated layouts can call for 10%-15% or more. A pitch of 6:12 or steeper, limited staging, or a two-story roof can also raise installation labor because movement and handling take longer.
Ask the contractor to state the measured roof area and waste allowance. If the estimate prices underlayment by the square, verify that the contractor means a roofing square of 100 square feet, not a product roll.
How Much U20 Installation Adds to a Roof Replacement
When the roof is already stripped and ready for new materials, installing underlayment is generally a smaller part of the project than tear-off, shingles, flashing, and other roofing work. An incremental allowance of $0.20-$0.60 per square foot puts a 2,000-square-foot roof at about $400-$1,200 for material and installation, depending on access, scope, and local rates.
Labor is usually cheaper to add during a planned reroof than as a separate small job. Roofing crews may charge a minimum trip or setup fee for limited work. A contractor’s labor rate, crew size, and productive hours vary; steep or obstructed roofs can take longer than a clear, low-pitch roof of the same area.
Why U20 Prices Differ by Retailer and U.S. Region
Local store pricing, inventory, shipping distance, and contractor purchasing agreements can shift the roll price. As a planning estimate, rural buyers or customers far from a distributor may see total material costs 5%-15% above a well-stocked metro market because of freight or limited availability. Large metro areas can also have higher labor rates, even when product prices are competitive.
Compare the delivered price per square foot, not just the roll sticker price. A lower-priced roll may lose its advantage if shipping is high or its listed coverage differs. For contractor bids, compare the U20 product, roof-area measurement, and installation scope on each quote before judging regional price differences.
Delivery, Tear-Off, and Deck Repairs That Raise the Total
Underlayment delivery may be included in a roofing-material order or charged separately. A small order, long distance, or special delivery timing can add roughly $15-$100. Existing shingles must generally be removed before new underlayment is laid during a full replacement; that tear-off is part of the broader roofing project and should not be confused with the U20 product price.
Unexpected deck damage is often a larger cost swing than the underlayment itself. Replacing sheathing may run about $3-$8 per square foot of affected area, depending on material and local labor. Ask the roofer to quote a per-sheet or per-square-foot repair rate and explain how approval is handled if damaged wood is found.
Three U20 Roof Scenarios With Estimated Totals
The examples below use approximate roof area and installed add-on rates, not a complete reroof price. They assume normal access and no sheathing repair; local bids and contractor packaging can change totals.
| Scenario | Estimated scope | Approx. total |
|---|---|---|
| Small, simple roof | 1,200 sq ft; material plus labor at $0.20-$0.35/sq ft | $240-$420 |
| Typical mid-size roof | 2,000 sq ft; material plus labor at $0.30-$0.45/sq ft | $600-$900 |
| Large or difficult roof | 3,000 sq ft; material plus labor at $0.40-$0.60/sq ft | $1,200-$1,800 |
The area-based totals are useful for comparison, but a written bid should show the actual roof measurement and included tasks. If a quote is far outside these ranges, ask whether it includes tear-off, repairs, extra materials, or other roof components beyond U20.
Ways to Lower the U20 Cost Without Cutting Coverage
Get at least two itemized estimates and compare roll coverage, installation rate, waste allowance, delivery, and repair charges. Buying enough material in one order may reduce freight, but avoid ordering solely by house floor area; use the measured roof area and a stated waste percentage.
Keep the scope focused and avoid paying twice for bundled work. If the underlayment is already included in a reroof quote, request its product specification and coverage instead of adding a separate line item. Do not reduce required laps or omit damaged-deck repairs to save money; ask the installer to confirm the product’s application instructions and the scope needed for the roof design.
