Roofing, Siding & Exterior Remodeling in Delaware County, PA

Installations, Replacements & Repairs

Delaware County’s homes work hard — and most of them have been doing it for a long time. “Delco” is one of the most established suburban areas in the Philadelphia region, packed with twin homes, row homes, post-war Cape Cods, and classic colonials. Dexteriors Roofing & Siding keeps those homes protected with GAF Certified roofing, siding, windows, doors, and gutter work across the county.

Dexteriors LLC was founded in 2023 by a team with 30+ years of combined exterior-remodeling experience. We’re fully licensed and insured in Pennsylvania — and we treat a Delco twin with the same care as a Main Line estate.

Towns and townships we serve in Delaware County

Delaware County is densely populated and full of distinctive home types. We regularly install in Media, Drexel Hill, Springfield, Newtown Square, Broomall, Havertown, Wayne, Radnor, Marple, Upper Darby, Lansdowne, Folsom, Aston, Brookhaven, Chester Heights, and Glen Mills.

Our coverage includes Marple Township, Upper Providence, Middletown Township, Edgmont Township, Concord Township, Thornbury, Newtown Township, Haverford Township, and Radnor Township. We also serve the historic boroughs of Media, Wayne, and Swarthmore, plus the Philadelphia-adjacent communities of Upper Darby and Lansdowne.

Delaware County encompasses a wide range of housing: 1920s–1950s brick twins and rowhomes in Upper Darby and Lansdowne, 1950s–1970s ranches and split-levels in Springfield and Drexel Hill, mid-century moderns scattered throughout, larger estate homes in Radnor and Newtown Square, and new construction in the western portions of the county. Each requires a different installation approach.

Why Choose Dexteriors in Delaware County

Delaware County has one of the oldest, densest housing inventories in the region — and that shapes every exterior conversation here. Twin homes and row homes are everywhere, which means shared walls, shared roof planes, and tight spacing between properties. Roofing and gutter work on these homes calls for careful detailing at party walls and precise water management, since there’s little room for runoff to go wrong before it reaches a neighbor’s foundation.

The county’s enormous stock of post-war Cape Cods and mid-century colonials means a huge number of Delco roofs are well past — sometimes decades past — their intended service life, often carrying two or even three layers of old shingles that should have come off long ago. Original wood windows and dated aluminum or early-vinyl siding are common, quietly costing homeowners money every heating season.

Toward the Main Line edge — Radnor, Haverford — the housing skews to larger historic homes with their own roofing complexity. Whatever corner of Delco you’re in, the freeze-thaw winters and storm-prone summers of southeastern Pennsylvania are working on your exterior. The free consultation sorts out what genuinely needs attention.

 Trustindex verifies that the original source of the review is Google. I have used Dexteriors for years, and they have delivered every single time. The quality of service is a given, they are as good as it gets.

What sets them apart is how personable they are. It is truly a pleasure to work with the crew.

I reached out to Matt when I had a leak in my ceiling after a storm recently, and he was over to take care of it quickly. Turns out my roof was way overdue to be replaced, and he got it done.

Don’t hesitate to give them a call if you need any work done. You will not regret it.

 Trustindex verifies that the original source of the review is Google. We had Dexteriors back to help with our roof after using them previously on a deck with roof covering 2 years back. Our roof was at the end of its life so it was time to go. Their pricing was fair, not cheap. We got 3 quotes and glad we went with Dexteriors because they really took care of the home, driveway, and cleaned up really well. You can tell the guys we worked with really cared about doing great work. 10 out of 10!!!

 Trustindex verifies that the original source of the review is Google. Kevin and his team swapped out a few Provia windows at our home.  What really stuck out was how respectful and courteous they were inside of our home especially inside of our children's bedrooms. Will use again if needed.

 Trustindex verifies that the original source of the review is Google. Hands down the best experience we’ve ever had dealing with a contractor in over 35 years of owning a home.
Matt came out and gave us the estimate. He listened to what we were looking for and gave us advice where we needed it.
After we agreed to terms Matt took the reins from beginning to end. He dealt with the township, had the material delivered when he said he would, started the job on time,  stayed in constant contact with us on timeline which was helpful because we were dealing with some bad weather. He even apologized for contacting me too much (which there is no such thing with typical contractors).😂
Most importantly, his crew was very professional, respectful, and worked hard.
Five star rating is well earned and I would recommend these guys to anyone!

 Trustindex verifies that the original source of the review is Google. We are more than pleased with the experience Dexteriors provided! They did a thorough inspection of our roofing system during the estimate and found not only was our roof sheathing/decking undersized (only 3/8", home built circa 1958), but there was also mold on the existing sheathing, inside our attic space! Unfortunately, our soffit vents were originally installed incorrectly and impacted the existing structure. In addition, our gable vents conflicted with the (potential) airflow that would have come from the soffit ventilation, when paired with our existing ridge vents. Dexteriors provided the appropriate correction at a reasonable cost. During installation, the Dexteriors crew was professional and efficient. They replaced the entire sheathing and installed the new roof with modernized ventilation in just 1 day! We were more than impressed. Having a new, properly installed roofing system on our home gives us a profound piece of mind, that we will proudly pass on to the home's next owner (with transferrable warranty!), when the time comes. Thank you, Dexteriors!

Frequently Asked Questions

Do you work on twin homes and row homes?

Yes — they’re a core part of Delaware County work. Shared-wall roofing just requires proper detailing, which is standard practice for us.

Can you remove old layers of shingles?

Yes. Many Delco roofs carry multiple old layers; we tear off and properly replace rather than shingle over existing problems.

How quickly can you respond to a roof leak?

Roof leaks are a priority for us — reach out and we’ll get a repair specialist scheduled fast, before water damage spreads.

Are estimates free?

Always free, always no-obligation.

Delaware County Considerations: Older Housing Stock, Brick Architecture, and Permit Variations

Delaware County's older housing stock requires installation considerations that newer-build counties don't face as often. Many homes have original asbestos siding or transite shingles underneath newer materials — we address this safely during tear-off with proper containment. Original wood trim around windows and doors can often be preserved with careful work, maintaining the home's character.

Brick architecture is common throughout Delaware County, particularly in Upper Darby, Lansdowne, Springfield, and Drexel Hill. Roofing and window installation on brick homes requires specific flashing details to ensure water sheds away from the brick face and lintels. We handle these details as part of every install — they're easy to overlook with less experienced contractors but cause damage years later.

Permit processes in Delaware County vary by township. Newer outer-ring townships (Newtown, Edgmont, Concord) have standard permit processes. Older inner-ring townships (Upper Darby, Lansdowne, Folsom) sometimes have more detailed requirements due to denser building patterns. We handle all permit coordination, including any HOA architectural reviews in newer developments in Newtown Square and Chadds Ford area.
