Horsham’s not a cookie-cutter market. The township’s got two stories happening at once: the former Naval Air Station Joint Reserve Base Willow Grove, that 1,100-acre installation closed since 2011, is being redeveloped under the Horsham Land Redevelopment Authority with new commercial and residential construction that needs specialty flat and low-slope roofing. Meanwhile, the 1960s-1980s tract colonials and split-levels built while the base was active are on their second or third roof cycle, and those low-pitch garage additions and rear expansions are where standard shingles fail and specialty systems prove their worth. No neighboring township faces this exact pairing, and no contractor who parachutes in for storm season understands the difference.
Our Specialty Roofing team knows the local building stock. We’ve replaced TPO on workshop additions in Horsham where the original builder used residential-grade membrane on a structure that needed commercial thickness. We’ve fixed transition flashing on split-levels near Horsham Road where three previous roofers patched and walked away. We arrive with the right materials, the right crew, and the intent to finish in one trip. That’s how we’ve worked for over 42 years.

We recently serviced a 19044 home on a property near County Line Road, where a detached workshop’s structure needed a roof that could handle more than standard residential loads. We specified a proper TPO system with appropriate membrane thickness and fastening pattern, ensuring the building envelope held up under the same wind and snow loads as the main house. Many crews would have under-spec’d it. We don’t.
Our Specialty Roofing Services in Horsham
TPO Roofing in Horsham
TPO - thermoplastic polyolefin - is the workhorse for Horsham’s low-slope additions, commercial spaces, and detached workshops. A typical TPO installation in Horsham runs $12,000-$18,000 for a residential low-slope section, or $8-$14 per square foot for larger commercial-scale applications. We install GAF and CertainTeed TPO systems with proper seam welding and fastening patterns that account for Horsham’s wind exposure along open acreage properties. The white reflective surface also cuts cooling loads on south-facing workshop roofs during July and August when humidity and afternoon heat peak.

EPDM Roofing in Horsham
EPDM rubber roofing remains a sound choice for Horsham’s older commercial buildings and for homeowners who want a proven system on a detached garage or workshop. Expect $10,000-$16,000 for most residential EPDM applications in the 19044 area. We use fully adhered or mechanically attached systems depending on the structure’s deck condition and wind exposure - critical on properties with longer service drives and less windbreak than denser neighborhoods. EPDM’s black surface can help with snow melt during Horsham’s nor’easter season, though it adds summer heat gain that TPO avoids.

Modified Bitumen in Horsham
Modified bitumen brings the durability of built-up roofing with easier installation and repair, making it practical for Horsham’s mixed-use properties and for homeowners who want a torched or self-adhered system on a workshop or outbuilding. Pricing typically falls between $11,000-$17,000 for residential-scale work. We see this specified often on structures at the former Naval Air Station redevelopment, where building standards require proven performance and where our authorization as an Atlas and Tamko installer matters for warranty compliance. The multi-ply construction stands up to foot traffic during HVAC maintenance, common on commercial and institutional buildings.

Solar Ready Roofing in Horsham
Horsham’s south-facing slopes and open acreage properties are increasingly attractive for solar arrays, but the roof beneath the panels needs to outlast the installation. Solar ready roofing means we engineer the deck, underlayment, and membrane to handle 25-30 years of panel weight, foot traffic, and penetration sealing before a single bracket goes on. For Horsham’s 1960s-1980s housing stock, this often means replacing rotted OSB or board sheathing we discover during tear-off - a cost drivers typically hit $2,000-$5,000 above the base roofing price, but one that prevents a $15,000 panel removal and reinstallation down the road. We coordinate with solar installers to ensure warranty compatibility across both trades.

Trusted Brands We Service in Horsham
We’re authorized installers for GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral - seven manufacturer lines, and we stock the core Horsham-appropriate SKUs at our Philadelphia facility for turnaround that out-of-town crews can’t match. For TPO and modified bitumen work, that means the right membrane thickness, the proper seam tape, and the manufacturer-approved fasteners for Horsham’s wind zone. We don’t substitute. The brand on your estimate is the brand on your roof, and the warranty paperwork goes straight to you, not into a black hole.
Common Specialty Roofing Problems We See in Horsham Homes
- Low-slope garage roof failures at the main wall transition. On split-level and colonial homes along the grid streets radiating off County Line Road and Horsham Road, the low-slope garage roofs consistently fail at the transition flashing where they tie into the main two-story wall. Original 1970s builders executed this detail poorly, and replacement roofers often skip it on re-roof jobs. We address it proactively - removing siding if needed, installing proper step flashing, and sealing with compatible membrane - because callbacks cost us more than doing it right the first time.
- Standard-duty materials on heavy-duty structures. Horsham’s acreage properties with detached workshops and oversized buildings need commercial-grade membranes, fasteners, and edge details that residential-grade products cannot provide. Using standard TPO thickness or residential fastening patterns on a 2,000-square-foot workshop leads to billowing, seam separation, and premature failure during nor’easter wind events.
- Improper membrane specification for wind exposure. Properties with longer service drives and open exposure face higher wind loads than sheltered suburban lots. Insufficient fastening or inadequate membrane weight leaves the roof vulnerable to uplift. We calculate wind exposure by structure location and specify accordingly - not one-size-fits-all.
- Condensation and deck rot on low-pitch additions. Horsham’s humidity swings and freeze-thaw cycles trap moisture in poorly ventilated low-slope sections. When we tear off, we frequently find rotted OSB or board sheathing that the homeowner couldn’t see from below. We quote the replacement upfront, document with photos, and never proceed without written approval.
