We Know Allentown Homes

Allentown usually get hit with a combination of hard winters, humid summers, and significant temperature swings, which can put more stress on roofing systems than homeowners typically expect.

Older neighborhoods like Old Allentown, Allentown West End, and South Allentown tend to have homes from the 1940s–1970s — many still on their original decking. We routinely find wet or rotted plywood on these projects that cheaper contractors miss (or ignore). Our process always includes a full deck inspection before any shingles go down.

We carry Pennsylvania Home Improvement Contractor license PA164856 and pull all required permits for work in Allentown and Lehigh County.

How Herts Roofing Works —
Start to Finish in Allentown

No subcontractors. No disappearing after the job. Every project follows the same proven process — and we document it every step of the way.

1

Free In-Person Inspection & Estimate

We come to your Allentown home, inspect the roof, siding, or deck in person, and provide a written, itemized estimate. No ballparks, no guessing. We photograph problem areas so you can see exactly what we see.

Same-day or next-day availability Written quote — no verbal estimates Photos of all problem areas No obligation
2

Material Selection & PA Permit

Once you approve the quote, we handle the Pennsylvania permit application and order your materials. We walk you through shingle colors, siding profiles, or decking options so you're confident in the choice before work begins.

We pull the Allentown permit — you don't Owens Corning shingle options Trex composite deck selections Financing paperwork if applicable
3

Full Tear-Off Down to the Decking

We remove all existing layers down to the plywood decking — not just the top layer. This is where cheaper contractors cut corners. Seeing the raw decking lets us catch rotted plywood, soft spots, and structural issues before they're buried under a new roof.

Complete layer removal Full deck board inspection Rotted plywood replaced same day Price agreed upfront — no surprise charges
4

Waterproofing System & Installation

We install a complete waterproofing system before any shingles go down — critical for Allentown's freeze-thaw cycles and ice dam season. Ice and water barrier at all vulnerable edges, synthetic underlayment for full coverage, then shingles installed to manufacturer specs.
