Siding Contractors in Philadelphia

For more than 40 years, Union Roofing has been one of the trusted siding contractors in Philadelphia, and one of the siding companies Philadelphia homeowners have relied on since the early 1980s. Siding is one of several exterior services we handle in-house, alongside roofing, windows, gutters, and chimneys. New siding boosts curb appeal, adds real value to your property, and lowers energy costs, and our A+ rating with the Better Business Bureau reflects the workmanship behind every installation.

When to Repair vs. Replace Your Siding

Not every siding problem calls for a full replacement, and we will tell you honestly which one you need. If the damage is isolated, a few cracked or dented panels on one wall, repair is usually the smarter, more affordable fix. When the issues are widespread, such as warping across multiple walls or water damage behind the siding, replacement is almost always more cost-effective in the long run.

Age is another useful guide. Vinyl siding typically lasts 20 to 40 years, aluminum 30 to 50, and fiber cement 30 to 50 or more. Watch for these common signs that it may be time for siding replacement in Philadelphia:

• Siding that is broken, cracked, faded, or peeling
• Water damage, often with accompanying mold and mildew
• Damage appearing on interior walls
• Energy bills climbing higher than they used to be

Siding Materials We Install and Repair

The right material depends on your budget, your home’s style, and how much maintenance you want to take on. As an experienced vinyl siding contractor in PA and a fiber cement siding installer, we help you weigh the trade-offs honestly.

Vinyl Siding

The most popular choice for good reason: durable, affordable, low-maintenance, and available in a wide range of colors and textures to match any architectural style. An occasional wash is usually all it needs to keep looking sharp.

Fiber Cement Siding

A premium option, including James Hardie-style products, that is fire resistant and built to last 30 years or more. It holds paint beautifully, so you can refresh the color of your home down the road.

Aluminum Siding

Aluminum is a long-lasting metal option, typically good for 30 to 50 years, and you’ll still find it on plenty of older homes around the Philadelphia area. It won’t rot, but it can dent from hail or impact and its finish can fade over time. We repair dents and damaged sections in aluminum siding in Philadelphia, and when a wall is past saving we’ll talk you through whether to replace it with aluminum or move to vinyl or fiber cement.

Wood and Engineered Wood Siding

Traditional wood siding has a warm, classic look but needs repainting or resealing over time, and left alone it can develop bubbles, blisters, and dry rot. We repair wood siding, and we also install engineered wood products like LP SmartSide, which give you the real-wood look with modern durability and easier upkeep, a strong middle ground for homeowners who want character without the heavy maintenance.

How to Choose a Siding Company in Philadelphia

There are plenty of siding companies in Philadelphia, and the difference between them usually shows up years later. Before you sign with anyone, check that the contractor:

• Is licensed and insured, so you’re protected if something goes wrong on the job.
• Knows Philadelphia homes, including row homes, party walls, tight access, and historic district requirements.
• Gives you a detailed written estimate that spells out materials, scope, and what happens if hidden damage turns up.
• Explains the warranty, both the manufacturer’s coverage on materials and the company’s own workmanship.
• Has real reviews from local customers you can read before you decide.
• Can handle the rest of your exterior, so your roof, gutters, and windows don’t need a separate contractor.

Union Roofing checks every one of those boxes, and we’re happy to answer any of these questions during your free estimate.

The Siding Installation Process

Knowing what to expect makes the whole project easier. Here is how a typical siding installation in Philadelphia unfolds. Most homes take three to five days, depending on size.

• Day 1 — Prep and removal: We deliver materials, set up the site safely, and carefully remove the existing siding.
• Days 2–3 — Inspection and weatherproofing: We inspect the sheathing underneath, which often reveals hidden damage we discuss with you before moving on. Then we install the moisture barrier and house wrap and add flashing around windows and other penetrations.
• Days 3–5 — Siding installation: We install the new siding with proper expansion allowance, complete the J-channel and trim work, and match the soffit and fascia.
• Final walkthrough: Careful caulking, a thorough cleanup, and a walkthrough with you to confirm everything meets our standard and yours.

What Quality Installation Actually Involves

The difference between a five-year siding job and a 25-year one is rarely visible from the curb, it lives in the house wrap and the flashing. Done right, these are the details that keep water out and your siding on the wall for decades:

• Nails set on the slot, not driven tight, so vinyl can expand and contract with temperature changes
• J-channels squared and level, corner posts plumb
• Trim painted or matched cleanly to the rest of the home
• House wrap and flashing installed correctly around every window and penetration
• Ongoing cleanup so your property stays tidy throughout the job

Working on Philadelphia Row Homes and Historic Areas

Philadelphia’s housing stock has its own quirks, and 40 years of local work means we know them well. Row homes bring party walls, neighbor walls, and tight access to plan around. In historic districts like Society Hill and Old City, materials and colors may need to match the neighborhood’s character or gain historic commission approval. And in older, pre-1950s homes, removing the old siding often exposes sheathing that needs repair, something we address transparently as we find it, never tacked on as a surprise at the end.

Warranty and What We Stand Behind

Your siding is backed on two fronts. Manufacturer warranties cover the materials themselves and vary by product, ranging from 25 years to lifetime coverage. On top of that, Union Roofing stands behind our own workmanship. Our A+ rating with the Better Business Bureau and more than four decades serving the Philadelphia area speak to how seriously we take that commitment. Ask us about current warranty terms during your free estimate.
