How Much to Refelt a Flat Roof: Complete Cost Breakdown

Refelting a flat roof typically costs between $4.50 to $12 per square foot in Queens, with most homeowners paying $2,800 to $7,500 for a standard residential flat roof. The total price depends on your roof size, felt type, and condition of the existing surface.

Look, I've been doing flat roofs in Queens for over two decades, and I get this question almost daily. Last week alone, I quoted three different refelting jobs on Astoria Boulevard, and the costs varied wildly based on what we found up there. Here's what you really need to know about refelting costs in our area.

Basic Refelting Cost Breakdown

The square footage of your roof is your starting point. Most residential flat roofs in Queens range from 800 to 1,500 square feet. Here's how the numbers typically break down:

• Standard 3-layer built-up felt: $4.50-$6.50 per sq ft
• Modified bitumen felt systems: $6-$9 per sq ft
• Premium torch-down membrane: $8-$12 per sq ft
• Labor costs in Queens: $2-$4 per sq ft

So for a typical 1,000 square foot flat roof, you're looking at $4,500 to $12,000 total. But here's the thing - I can't tell you how many times I've given someone a quote only to find additional issues once we start tearing off the old felt.

What Affects Your Refelting Cost

The condition of your roof deck makes a huge difference. If the decking is solid, we can lay new felt right over a cleaned surface. But if there's water damage or rot - which happens a lot here with our harsh winters and summer storms - you're looking at additional costs.

Roof access is another big factor in Queens. Some of these older buildings have terrible access, and getting materials up three or four stories without an elevator? That's going to cost extra. My crew Carlos always jokes that half our job is just getting the stuff up there.

The type of felt system you choose also impacts price significantly. Standard organic felt is cheaper upfront but doesn't last as long in our climate. Modified bitumen costs more initially but handles the freeze-thaw cycles we get much better.

Additional Costs to Consider

Permits in Queens run about $150-$300 depending on your exact location and the scope of work. Some areas require additional inspections, especially in flood zones near the water.

Deck repairs can add $3-$8 per square foot if we find rotted plywood or damaged joists. This is probably the biggest surprise cost I see. Just last month on 47th Avenue, what started as a simple refelting job turned into a $3,000 deck repair because previous contractors had ignored obvious leak damage for years.

Edge work and flashing replacement typically adds $8-$15 per linear foot. This includes parapet walls, roof-to-wall transitions, and penetrations for vents or HVAC equipment.

Material Options and Their Costs

Three-layer built-up roofing (BUR) is still popular in Queens because it's cost-effective and works well on our flat roofs. The base sheet goes down first, followed by intermediate plies, then a cap sheet with granules. Total material cost runs $2.50-$4 per square foot.

Modified bitumen is what I recommend for most residential jobs. It's basically asphalt with rubber or plastic modifiers that make it more flexible. The material costs $3.50-$6 per square foot, but it lasts longer and handles our weather better.

SBS (rubber-modified) versus APP (plastic-modified) - both work, but SBS stays flexible in cold weather, which matters here. APP is torch-applied and creates a stronger bond, but requires more skill to install properly.

Labor and Installation Factors

Labor costs in Queens have gone up significantly in recent years. Good roofers are harder to find, and everyone's busy. Expect to pay $2-$4 per square foot for labor, depending on the complexity of your roof.

The removal and disposal of old roofing materials adds cost too. We charge about $1-$2 per square foot for tear-off and disposal. The landfills have gotten more expensive, and some of the older felt contains materials that require special handling.

Weather delays can extend the project timeline, especially during fall and winter months. Most contractors build some weather contingency into their pricing, but extended delays might result in additional costs.

When Refelting Makes Sense

If your current felt roof is less than 15 years old and showing isolated problems, spot repairs might be sufficient. But when you've got widespread blistering, multiple leaks, or significant granule loss, refelting is usually your best option.

Here's what I tell customers: if you're spending more than $500 annually on roof repairs, it's time to consider refelting. The math is pretty simple - a new felt roof should last 15-20 years with proper maintenance.

The timing matters too. Fall is typically the best time for refelting in Queens because the weather is more predictable, and contractors aren't as rushed as during emergency repair season.

Getting Accurate Quotes

Any contractor worth hiring will want to inspect your roof before giving you a firm quote. Be suspicious of quotes given over the phone or based only on square footage.

Make sure quotes include material specifications, not just generic "felt roofing." You want to know exactly what type of base sheet, intermediate plies, and cap sheet they're planning to use. The quality difference between products can be substantial.

Get at least three quotes, but don't automatically go with the lowest price. I've seen too many botched refelting jobs that ended up costing twice as much to fix properly. Ask for references from recent jobs, and actually call them.

Maintaining Your Investment

Once you've invested in refelting, proper maintenance extends the life significantly. Annual inspections cost $150-$250 but can catch small problems before they become expensive repairs.

Keep drains clear - this is huge in Queens with all the debris from trees and nearby construction. Clogged drains are probably the number one cause of premature felt roof failure I see.

Address small repairs immediately. A $200 repair today prevents a $2,000 problem next year. I always tell customers to call at the first sign of any interior water stains or ceiling discoloration.
