Replacing a roof in Allentown means dealing with a building stock and a climate that punish shortcuts. From the slate mansards of Old Allentown rowhouses to the brick twins in Whitehall and the 1990s colonials in Lower Macungie, every roof here faces the same Lehigh Valley pressure: nor'easters, ice storms, freeze-thaw cycles, and humid summer thunderstorms. If your current roof is leaking, hail-dented, or simply exhausted, professional Metal Roof Replacement in Allentown gives you a permanent answer instead of another patch. We tear off the old system, inspect and repair the decking, and install a complete new metal roof with full ice-and-water protection underneath. No layers buried, no surprises hidden under old shingles. Whether you own a Victorian twin near the Old Fairgrounds or a stone farmhouse out toward Slatington, the replacement has to match the structure and the weather, not a catalog photo. Call (610) 600-9879 and we will walk the roof with you before anything is ordered. You can also review our metal roof installation process to see how a new system is built from the deck up.
Why Metal Roof Replacement Matters on Allentown's Older Roofs
Allentown sits between South Mountain and Blue Mountain where the Lehigh River cuts the valley, and that geography funnels cold air and moisture straight at your roof. Ice dams form along eaves on the 1900s to 1930s Victorians in the West End and the brick rowhouses downtown, and once water backs up under aging shingles or failing slate, the damage runs into rafters and plaster. The oaks, maples, and sycamores that shade those streets also fill gutters and valleys every fall, which accelerates rot at the edges.
- We remove every layer of the old roof so we can see the decking, because soft spots and rotted sheathing are common under 30-year-old shingles.
- We replace damaged decking and install full ice-and-water shield at the eaves and valleys, which is where Lehigh Valley ice dams do their worst.
- We install a complete metal system with proper underlayment, fasteners, and ventilation, so the new roof performs as one assembly.
- We haul away all old roofing and debris the same day, leaving the property clean.
That full tear-off approach is what separates a real replacement from a cover-up, and it matters most on the older homes where the decking has already taken water.
Key info: On a 1920s West End Tudor with a steep slate mansard, we routinely find original board sheathing that needs renailing and partial replacement before any metal goes down. Skipping that step is how a new roof fails in year three.
Permits for a full replacement or re-roof are commonly required in Allentown and the surrounding municipalities, and thresholds and inspection requirements vary by jurisdiction. Always confirm the current rules with the local building department before work starts. You can start with the City of Allentown's official site at allentownpa.gov.
How We Run a Metal Roof Replacement in Allentown
A replacement is a sequence, and the order matters. We start with a full inspection and measurements, then protect the landscaping and set up fall protection before a single shingle moves. On the steep roofs common in Old Allentown and the West End, staging and roof anchors go up first. We tear off in controlled sections so the house is never wide open to a passing storm.
- We inspect the roof, attic, and decking, then document the existing condition with photos for your records and any insurance paperwork.
- We pull the required permit with the local building department and schedule the tear-off around the forecast, not around convenience.
- We remove the old roofing and haul it away, then repair or replace any rotted sheathing and renail the deck.
- We install underlayment and full ice-and-water protection at eaves, valleys, and penetrations.
- We install the new metal panels or shingles with the correct fasteners, then flash chimneys, skylights, and walls.
- We clean the site, walk the roof with you, and hand over the documentation.
Every step is documented, and you get a final walkthrough before we consider the job closed.
Key info: On a post-war brick ranch in Whitehall with a low-slope porch roof, we replaced the decking over the porch and tied the new metal into the main roof with a continuous transition flashing. That transition is where the old roof had leaked for years.
If your existing metal roof is still structurally sound but worn, replacement is not always the answer. Our metal roof repair service covers situations where re-fastening or panel work keeps the roof in service.
Replacement Approaches We Use Across the Lehigh Valley
Not every Allentown roof calls for the same system. The right approach depends on the roof pitch, the building's age, historic district or HOA rules, and how long you plan to own the property. Here is how we match the method to the house.
| Approach | Description | Best for |
|---|---|---|
| Full tear-off and standing seam | Old roof removed to the deck, new underlayment, concealed-fastener standing seam panels installed. | Long-term owners who want the cleanest look and the fewest fasteners exposed to weather. |
| Full tear-off and exposed-fastener panels | Old roof removed, deck repaired, corrugated or ribbed panels screwed down with washered fasteners. | Barns, garages, and budget-conscious homes where straightforward performance matters more than a sleek profile. |
| Full tear-off and metal shingles or stone-coated steel | Old roof removed, new substrate and underlayment, then shingle-profile or stone-coated panels installed. | Historic districts and HOAs where the roof must read as slate or cedar from the street. |
| Full tear-off with copper or specialty metal | Old roof removed, substrate prepared, copper or specialty metal installed with soldered or folded seams. | Moravian stone buildings in historic Bethlehem and high-end homes where the metal itself is the design feature. |
| Replacement with retrofit over existing shingles | New metal installed over an approved existing shingle layer where code allows, with a thermal break and new fasteners. | Homes where the deck is sound and the existing layer count stays within code limits. |
We will tell you which of these fits your roof after we see it, and we will tell you when the cheaper option is the wrong one.
Metal Roof Replacement Cost in Allentown: What to Expect
Most homeowners want a number before they call, and that is fair. As a starting point, metal roof replacement in Allentown runs from $9 per square foot for a basic full tear-off and panel system, and the final price depends on the roof, not on a brochure. The figure covers tear-off, disposal, decking inspection, underlayment, and the new metal system. What moves it is the pitch and complexity of the roof, the condition of the sheathing once we open it up, the panel profile you choose, and how much flashing and penetration work the house needs.
Access changes the number too. A rowhouse in Old Allentown with a shared wall and narrow alley costs more to stage than a ranch in Salisbury with a wide driveway. Historic district or HOA design review can also add time and material cost if the profile and color must be approved. That is why we give a written scope with line items instead of a single lump figure. Get two or three estimates, compare the scope line by line, and be suspicious of any bid that skips the decking inspection. Our pricing overview lays out how the ranges are built so you can compare bids on equal terms.
What to Look For in a Metal Roofing Contractor Near Allentown
Hiring for a replacement is a bigger decision than hiring for a repair, so check the contractor before you check the price. A legitimate metal roofing contractor near me in Allentown will carry current liability insurance and workers' compensation, and will hand you a certificate without being asked. Ask for local references on homes similar to yours, not just photos of new construction. Confirm who pulls the permit and who is on the roof, because subcontracting the install is common and worth knowing about.
Historic districts and HOAs in the Lehigh Valley can restrict panel profile and color, so ask the contractor whether they have worked under design review before. A contractor who has not will cost you weeks. Also confirm the warranty terms in writing, including whether the manufacturer's warranty depends on certified installation. Our contact page is the fastest way to schedule a walkthrough and get those answers in person.
