When you need an Allentown roofing contractor, you want to make sure you’re working with roofers that know the city’s rich history. Catalfano Brothers has offered roofing services to Allentown homeowners and throughout Lehigh County since 2003. While the land was renamed Allentown in 1838, the homes here have been built and developed as early as the mid to late 1700s. With three historic districts (Old Allentown, Old Fairgrounds, and West Park), there are many homes here that have need special attention when hiring a roofing contractor.

If you live in a 18th/20th century rowhome or twin in Center City Allentown, those flat/low-slope rear roofs and shared party walls are common leak areas. If you live in the historic district with slate, decorative trim, dormers, and box gutters, those often need special repair and matching. You may be dealing with attic ventilation due to Lehigh Valley’s freeze-thaw cycles. Catalfano Brothers is an experienced Allentown roofing contractor that knows how to work around these unique challenges that Allentown homeowners face. If you need a roofing contractor in Allentown, contact Catalfano Brothers today for experts that can make sure you’re taken care of.

Allentown Low-Slope Roofing

Low-slope roofs are common on rowhomes, additions and commercial buildings. Center City Allentown is packed with rowhomes that have flat rear roofs, and those are some of the most common leak calls we get there. We install fiberglass, EPDM and TPO, and each one has its own strengths depending on how the roof is used and how much foot traffic it gets. Whatever we install, we pay extra attention to the edges and drains, since that’s where most flat roof leaks begin. For a free estimate, call us at (215) 884-1266.

Honest Roof Repair Advice in Allentown

If you’ve already had a roofer tell you that you need a whole new roof, it might be worth a second opinion. On Allentown rowhomes and twins, a leak near the party wall can come from either side, so we trace it before we fix anything. There are a lot of cases where a roof can be repaired and keep going for years, and that can save you thousands. We’ll inspect it, take photos of what we find and walk you through your options. Our goal is to do what’s best for your house and your budget, and to do it safely. Call (215) 884-1266 to schedule a visit.

Roofing Contractors Serving Allentown

For more than 20 years, homeowners have called Catalfano Brothers for roof repairs, roof replacements and new installs. Allentown has everything from 1800s rowhomes in the historic districts to postwar singles on the edges of the city, and we work on all of it. We work with asphalt shingles, cedar shakes, slate, tile and metal, so we’re not going to push one material on you just because it’s the only one we know. CertainTeed lists us as both a Select ShingleMaster and a 5-Star Vinyl Siding and Trim contractor, and our crews have worked across Lehigh County for years. We also handle siding, windows, doors and gutters.

Some Signs You Need a Roofing Contractor in Allentown

Your roof is leaking: Water stains on your ceiling or walls mean water is getting in somewhere. Have the roof inspected before the damage spreads.

Shingles are missing: Check your roof every so often, especially after a storm. Gaps leave the layers underneath exposed.

There’s mold or mildew: Growth on the roof can point to poor ventilation, trapped moisture or a hidden leak. Deal with it quickly.

Your energy bills jumped: A sudden increase can mean an insulation or ventilation problem in the attic.

Allentown Shingle Roofing Contractor

Asphalt shingles are on more homes than any other roofing material, and for good reason. They cost less than most other options, they come in a lot of colors and they fit the look of just about any house. In the West End and the neighborhoods farther out, most Allentown homes have shingle roofs that are coming due for replacement. Today’s architectural shingles are thicker and hold up better in wind than the flat 3-tab shingles that were common years ago. Our crews keep the job site safe and clean up debris as they go. Call (215) 884-1266 to get an estimate on a new shingle roof.

Allentown Commercial Roofing

Commercial roofs come with different challenges than homes. They’re bigger, they’re usually flat or low-slope and there are often people working inside while the job is going on. Allentown’s downtown and Hamilton Street corridor are full of older commercial buildings with flat roofs that need regular attention. Our commercial crews have done everything from small repairs to complete roof system installations, and we work closely with building owners and property managers to keep things running smoothly. We also offer service plans that help extend the life of your roof. Property owners can call (215) 884-1266 to talk through a project.

Slate Roof Replacement and Repair in Allentown

Slate is a premium roof, and it should be treated like one. Homes in Old Allentown and the Old Fairgrounds district often still have slate fronts, and those can usually be repaired to match. We match new slates to the color and size of the ones already on your roof, and we install them with copper nails or hooks so they last as long as the rest of the roof. From a few broken pieces to a full replacement, we’ll find the right solution at a fair price. Contact Catalfano Brothers to talk about your slate roof.

Roofing Questions From Allentown Homeowners

How long does a new roof usually last?

A properly installed roof typically lasts:

• Architectural shingles: 30-50 years
• Metal roofs: 40-70 years
• Slate: 100-200 years

How long yours lasts depends on the materials, ventilation, weather exposure and maintenance.

Should I repair or replace my roof?

Many roofs can be repaired, and we’d rather fix a roof than sell you a new one you don’t need. If the roof really is at the end of its life, we’ll show you why before we talk about replacement.

Why do the flat back roofs on Allentown twins and rowhomes leak?

Water sits on flat roofs instead of running off, and over time that opens seams and breaks down older coatings. We repair or replace them with modern membranes that stay watertight.

What types of roofs do you install?

We install and repair asphalt shingles, cedar shakes, slate, tile and metal, plus EPDM, TPO and fiberglass on flat and low-slope roofs.

How much does a new roof cost?

Most homeowners spend between $7,500 and $25,000. Where your roof falls in that range depends on its size and pitch, the material you choose, the condition of the decking and how many old layers have to come off. Our written estimates are free.
