Commercial Roofing in Farrell, PA
In-house crews out of our Sharon, PA shop.
Farrell commercial roofing is the mill-era warehouses and low-slope light-industrial buildings along the old rail corridor, plus the smaller commercial buildings on Roemer Boulevard. It is a different job than Hermitage commercial and a very different job than downtown Sharon commercial.
Mill-Era Warehouse and Light-Industrial
The largest Farrell commercial roof profile is the low-slope mill-era warehouse and light-industrial buildings — many built between 1910 and 1940 with steel deck over open steel framing and a modified bitumen or older built-up asphalt roof. On those buildings the correct replacement is usually a fully-adhered EPDM or PVC single-ply over new tapered ISO insulation, with a full moisture survey and any wet deck material removed and replaced.
We do not overlay Farrell mill-era commercial roofs — the existing insulation is too saturated at this point, and adding weight to older steel framing is not a call to make lightly.
PVC Over EPDM on Chemical-Exposure Buildings
For former manufacturing buildings in Farrell that had chemical exposure — solvents, oils, machining fluids — PVC is the right specification over EPDM. The chemical resistance of PVC handles trace residues on the deck and around penetrations that would degrade an EPDM seam. Cost differential is real; on chemical-exposure buildings it is warranted.
Roemer Boulevard Storefront Commercial
The smaller storefront commercial along Roemer Boulevard and cross streets is a similar profile to downtown Sharon commercial — masonry buildings from the pre-WWII era, low-slope roofs, parapet coping failures, aging modified bitumen. The replacement approach is the same: full tear-off, new insulation, TPO or EPDM top cover, new ES-1 metal edge, re-flashed penetrations.
What Is Commercial Roofing?
Commercial roofing covers the flat and low-slope systems on Farrell businesses, churches, apartment buildings, and light industrial properties — single-ply membrane, modified bitumen, and coating restorations. These roofs fail differently from residential shingle: the enemy is standing water, seam failure, and penetration detail, not wind uplift on a steep slope.
Low-Slope Systems We Install in Farrell
- 1TPO and PVC single-ply: heat-welded seams, high reflectivity, the default for most new low-slope work.
- 2EPDM rubber: durable and forgiving on complex roofs, seamed with tape or adhesive.
- 3Modified bitumen: torch- or cold-applied, still the right answer on many older decks.
- 4Silicone and acrylic coating restorations: extend the life of a sound but aging membrane without a tear-off and without shutting the business down.
What Matters on a Commercial Roof
- Solve the drainage. Tapered insulation and adequate drains — ponding water is what kills low-slope roofs.
- Detail every penetration, curb, and parapet properly. That is where nearly all commercial leaks originate.
- Phase the work around business hours so operations keep running.
- Set up a documented maintenance schedule; most manufacturer warranties require it.
What to Avoid
- Patching the same spot year after year instead of correcting the drainage.
- Coating over a wet, saturated substrate — it traps the moisture in.
- Crews without low-slope-specific training welding seams.
- Skipping the roof survey and moisture scan before a restoration.
Warning Signs on a Farrell, PA Home
- Ponding water still standing 48 hours after rain.
- Open, lifted, or fishmouthed seams.
- Blisters or ridges in the membrane.
- Interior ceiling tile staining, often far from the actual entry point.
- Failed sealant at curbs, drains, and rooftop units.
What Drives the Cost of Commercial Roofing in Farrell
- •Square footage and roof complexity — units, curbs, and penetrations.
- •Tear-off versus recover versus coating restoration.
- •Insulation R-value and whether tapered insulation is needed for drainage.
- •Membrane type and thickness, and the warranty term you want.
- •Access, staging, and whether work must happen after hours.

Path 1 — Insurance claim
For wind, hail, or storm-driven damage. We walk the roof with your insurance adjuster and document what we find so nothing that should be covered gets missed. We are not a public adjuster — that is a separate PA license — and we do not negotiate the settlement. We document damage, meet the adjuster, and rebuild what the carrier approves to code and to manufacturer spec.
Path 2 — Retail with financing
For roofs simply reaching the end of their life. 0% interest financing on shorter terms and long-term financing that keeps monthly payments low. Runs through a lending partner and is subject to credit approval. We walk through both paths in the free in-home estimate before you sign anything. See financing details →
