Line by line: tear-off of all layers and disposal by weight; a deck inspection with a stated price for replacing sheathing; insulation by type and thickness; a cover board over it; the membrane named by type and thickness in mils; the attachment method; every flashing and termination, from parapets and curbs to pipes, drains, scuppers and edge metal; and both warranties with lengths.
Two flat roof quotes are often not comparable at all, because one includes insulation and a cover board and the other lays membrane over whatever is there.
One to three days for a typical residential flat section, and the tear-off is often half of it. Weather constrains this roof more than any pitched one. The assembly must be dry when it is closed up, adhesives have minimum application temperatures, and it cannot be left half-finished overnight without a watertight tie-in. Crews will move your date rather than close a wet assembly, because trapped moisture is what shortens a flat roof's life.
Almost every residential flat roof is now a single-ply membrane, and which of the three you get sets both the price and the eventual failure mode. Read the quote for the name.
| TPO | EPDM | PVC | |
|---|---|---|---|
| What it is | Thermoplastic polyolefin | Synthetic rubber | Vinyl |
| Seams | Heat-welded | Glued or taped | Heat-welded |
| Relative price | Lowest in most markets | Close to TPO | Highest of the three |
| Weak point | Formulations differ by maker | Glued seams need maintenance | Price, and it stiffens with age |
The practical read: if a kitchen exhaust or grill vents onto the roof, PVC's grease resistance is worth paying for. In a cold climate on a simple roof, EPDM's flexibility and long record are hard to argue with; over conditioned rooms in strong sun, a white welded membrane keeps the assembly cooler.
Replace when the assembly is wet rather than the surface merely tired: water that ponds and never dries, blisters and ridges across the field, seams open in several places, insulation that gives underfoot, or a membrane already patched a dozen times. Jurisdictions following the International Residential Code generally require removal once a roof reaches two layers of covering.
Do not replace when the problem is a detail. One failed drain or a bad parapet flashing is a repair, and re-roofing over it is expensive misdiagnosis. Do not replace while drainage is still the underlying fault, because a new membrane over the same dead-flat deck will pond where the old one did. If the membrane is sound and only the surface has aged, a coating may buy years for far less.
Home Genius Exteriors holds Owens Corning Platinum Preferred status alongside James Hardie Elite Preferred and CertainTeed 5-Star contractor certifications, and covers roofing, siding, windows, doors, gutters and attic insulation. Reviewers name their project manager more often than almost anything else about the job, and describe them staying involved and checking in through to the finish. Siding and gutter work draws the warmest praise for how it looks once finished, and most installs wrap up in just a few days. Their free inspection is thorough and photo-led, with some homeowners noting drone footage of the roof itself. Promotional discounts are tiered by trade rather than applying across the board, so ask what your specific project qualifies for. If your roof is flat or low-slope, ask what warranty comes with it, since those systems are covered differently.
Long Home Products traces back to 1945 and is still run by the same family, four generations on, covering roofing, bath and siding along the East Coast. Its roofing warranty is one of the strongest available anywhere: up to fifty years, non-prorated and transferable, covering the full future cost of shingles or labor. The clearest thread through their reviews is a consultant who listens first: homeowners regularly describe someone who asked what they were trying to achieve before recommending anything, then answered every follow-up question patiently. Installers draw the same kind of praise once a job is under way: named crews, protected floors, and a site left clean. Roofing here is replacement rather than repair. Their outreach is active, so if you are only gathering information it is worth saying so plainly at the first call.
Best Choice Roofing’s genuine strength is in insurance claims. It is the single thing reviewers write about most, consistently across branches from Kentucky to Nevada. They describe a rep who photographs and documents the damage, then turns up in person to meet the insurance adjuster on the roof, which is the part homeowners say made the difference. Several reviewers also single out a rep for saying plainly when storm damage was not going to be covered, rather than pushing a claim that was not there. Roofs are typically stripped and replaced in a day, and the company also fits gutters, siding and insulation. Its warranty tiers are built on GAF, with claims filed directly to GAF, while its Owens Corning Platinum Preferred status is a certification rather than a warranty. It is worth keeping those two separate when you compare quotes. Because homeowners have found warranty transfer and repair coverage vary by location, ask your rep to confirm both in writing before you sign.
Pinnacle Home Improvements has been family-led since 1988 and works across Georgia, Tennessee, Alabama and North Carolina, covering roofing, windows, siding, doors and gutters. It is a GAF Master Elite contractor, a distinction held by a small share of roofers nationwide. Windows and siding are what homeowners write about most, across more than one of its markets, and they are specific about why: draft elimination, the finished look of new siding, and crews who removed their shoes on the way in. The salesperson is named and praised in nearly every positive review, and several note the consultation was educational rather than a pitch. One practical note: Pinnacle asks that both homeowners attend the in-home appointment, so plan for that when you schedule.
Victory Home Remodeling covers windows, roofing, siding and gutters across the Northeast and Mid-Atlantic (New Jersey, New York, Pennsylvania, Delaware and Maryland), installing and warranting house-branded systems supplied by established manufacturers: EnduranceX™ siding from Norandex, roofing materials from GAF. It is a GAF Master Elite contractor, a designation held by only about 2% of roofers nationwide. The process runs through a named salesperson and project manager, with a quality inspection at the end rather than a single handoff, and reviewers consistently describe the installation crews as clean, careful with the house, and quick to finish on the date first promised. Its warranty is genuinely one of the stronger ones in this category: lifetime, non-prorated on both labor and product, transferable once to the next owner, and it covers glass breakage regardless of cause. Get the full scope, including trim, siding tie-ins, and what the warranty covers, in writing before the crew starts.
Clear Choice Home Improvement is a family-owned company working across Massachusetts, New Hampshire, Rhode Island, southern Maine, Vermont and central Pennsylvania: a regional specialist rather than a national one. Metal roofing is where its reviews are strongest and most detailed: standing-seam roofs fitted in three or four days, crews working till dark, and one homeowner whose panel was repaired free of charge a year later. Homeowners regularly name their crew lead and project coordinator by name when a roof is finished. It is an Owens Corning Preferred contractor, and covers roofing, siding, windows, doors, gutters and bath. One thing worth knowing up front: Clear Choice does replacement and installation, not repairs.
