Fresh underlayment laid across the entire deck, locked in and ready for shingles.

Every row lined up straight, every seam overlapped properly, because what goes down first determines how well the roof protects for decades.

Another exterior brought back to life.

Clean lines. Proper drainage. Vented soffits for airflow. Fresh fascia wrap. New gutter system. New roofing system.

The details matter. Most homeowners notice the shingles, but the long-term performance of a roof depends on how all the components work together. Proper water management and ventilation help protect the structure, improve curb appeal, and extend the life of the entire system.

At Kohn Contracting, we don't just replace roofs—we build complete exterior systems designed to perform for years to come.

Another closing. Another happy client. 🏠

One of the most rewarding parts of our business is helping homeowners, Realtors, buyers, and sellers navigate repairs during real estate transactions.

When deadlines are tight and everyone is working toward the same goal, communication and responsiveness matter just as much as the repair itself.

We're grateful for the opportunity to work alongside great local professionals like Ashley and appreciate the trust she continues to place in our team.

Thank you for the kind words and continued support!

"Highly recommend Eric and his team! This is not my first time working with them, and once again they delivered exceptional service.

They were responsive, professional, accommodating to my clients' schedule, and moved quickly when we needed repairs completed during a real estate transaction. Communication was great throughout the entire process, and they made what could have been a stressful situation feel easy.

I appreciate the quality of work, honesty, and professionalism they bring to every job. I'll definitely be calling them again for future projects and client referrals."

Before & After | Balcony Restoration – Compass Pointe, Pasadena, MD

This balcony restoration is a great example of what happens when waterproofing is done correctly from the structure outward.

The existing railing system had deteriorated, allowing moisture to impact the assembly over time. We removed the old wood and vinyl railing system, replaced damaged sheathing, and rebuilt the balcony with a focus on long-term performance—not just appearance.

✔️ Removed existing rotted railing assembly
✔️ Replaced deteriorated roof sheathing
✔️ Installed new drip edge metal
✔️ Installed a Soprema Flintlastic 2-Ply Self-Adhered Waterproofing System
✔️ Ground out the existing mortar reglet and properly integrated new flashing into the masonry
✔️ Installed custom-fabricated 24-gauge counterflashing
✔️ Sealed all transitions and terminations with premium sealants where required
✔️ Installed new Fypon vinyl railing system
✔️ Installed new backer rod and sealant at adjacent window assemblies
✔️ Painted fascia trim for a clean, refreshed appearance

One of the most important details on this project was carrying the flashing system up the wall and into the masonry rather than relying solely on surface sealants. Proper flashing, counterflashing, and waterproofing details are what keep water out of the structure years down the road.

The end result is a balcony that not only looks beautiful but is built to manage water the way it should.

All in all, it turned out great, and we're proud of the finished product.

🏡 Project Progress Update – Exterior Renovation Underway

The siding portion of this renovation is really starting to come together, and the details behind the walls are just as important as the finished appearance.

This project includes a fully integrated exterior envelope system featuring a weather-resistant barrier, seam tape, new white trim, solid soffits at the rakes, and solid eaves designed to properly support an effective ridge ventilation system. Insulation baffles have also been installed to maintain a clear airflow path from the soffits to the ridge, helping maximize attic ventilation and overall roof performance.

We're installing CertainTeed Monogram D5 siding in Natural Clay, accented by Midnight Blue shutters, crisp white trim, and an upgraded exterior lighting package that will completely refresh the home's appearance.

What separates a quality exterior renovation from an average one isn't just the siding color—it's the complete system. Proper weather barriers, taped seams, ventilation components, moisture management, trim details, and installation practices all work together to protect the structure while improving energy efficiency and curb appeal.

Proud of the craftsmanship, proud of the crew, and excited to see the final transformation.

✅ PROJECT COMPLETE – SEVERN, MD ✅

Another roof in the books.

This homeowner chose the new GAF Timberline UHDZ® shingles in Charcoal, and the difference is noticeable even from the street.

In fact, while we were working, a neighbor stopped to ask why the roof looked different than his. His comment was simple:

"It just looks thicker and stronger."

He's right.

The UHDZ line features enhanced shadow lines, a larger laminated profile, and upgraded asphalt composition that creates a bolder, more dimensional appearance than traditional architectural shingles.

For us, the difference is obvious before the shingles even hit the roof. The bundles are noticeably heavier, and the finished product has a premium look that photographs well and looks even better in person.

This project included:

✔ Complete roof replacement
✔ GAF Timberline UHDZ® Shingles – Charcoal
✔ GAF WeatherWatch® Leak Barrier
✔ GAF FeltBuster® Synthetic Underlayment
✔ GAF Pro-Start® Starter Strip
✔ GAF Seal-A-Ridge® Ridge Cap System
✔ Cobra® Snow Country Advanced Ridge Vent
✔ New aluminum drip edge and flashing components
✔ Manufacturer-backed warranty protection

Thank you to the homeowners for trusting Kohn Contracting with their investment.

If your roof is 15-25 years old, has storm damage, or you're simply wondering how much life it has left, we'd be happy to help.

"Why do those shingles look different than mine?"

That was the question a neighbor asked us today while we were installing this roof in Severn, MD.

His exact words:

"From the ground, they just look thicker and stronger."

And honestly... he's not wrong.

What you're looking at is the new GAF Timberline UHDZ® shingle. While it shares the same family name as the popular HDZ, there are some significant upgrades.

✅ Dual Shadow Line Technology creates deeper dimensional contrast, giving the roof a more defined, architectural appearance from the street.

✅ Increased asphalt content and larger laminate profile contribute to a heavier, more substantial shingle compared to the standard HDZ.

✅ StrikeZone® nailing area remains one of the largest nailing targets in roofing, helping improve installation accuracy and wind performance.

✅ LayerLock™ Technology mechanically bonds the layers together for enhanced durability.

As roofers, one of the first things we notice is the weight. Carrying a bundle of UHDZ up a ladder feels noticeably different than carrying a standard HDZ bundle. More material. More mass. More presence.

From the ground, homeowners notice the shadow lines and depth.

From the roof, we notice the build quality.

It's one of the reasons more homeowners are stepping up to UHDZ when they're already investing in a new roof.

Not all shingles are installed the same. 👀

This is what a proper 6-nail pattern looks like on a laminated architectural shingle roof. Clean placement. Consistent spacing. High nails avoided. Proper fastening where the manufacturer actually wants them.

A few nails may not seem like a big deal… until the first real windstorm rolls through and shingles start visiting the neighbor’s yard like they pay taxes there.

High nailing is one of the most common roofing installation issues we see, and it can absolutely affect wind resistance, warranty coverage, and long-term performance.

Details matter.
That’s the difference between “looks good from the driveway” and a roof system installed to perform.
