Recent Maryland Home Improvements: Roofing, Siding, Skylights & Gutters

From complete roof replacements to exterior transformations, our crews at AHI Roofing & Remodeling have been busy helping homeowners throughout Maryland protect and improve their homes.

Our recent projects have taken us to Crofton, Rockville, Waldorf, and Gaithersburg, MD, where we've completed everything from new roofing systems and skylight installations to siding replacements, seamless gutters, and structural roof improvements.

Here's a closer look at five recent projects and what went into each one.

Crofton, MD – Complete Roof Replacement, Sunroom Roofing, Skylight & Gutter Upgrades

Our first project takes us to Crofton, Maryland, where the homeowner needed several exterior improvements, including a new pitched roof, a low-slope sunroom roof, skylight upgrades, and a complete gutter replacement.

We started by removing the existing shingles down to the roof deck, inspecting the underlying wood, and preparing the home for its new roofing system.

For the main roof, we installed GAF Timberline HDZ architectural shingles in Fox Hollow Gray, along with GAF ProStart starter shingles, Seal-A-Ridge hip and ridge shingles, Cobra Snow Country ridge ventilation, and protective ice and water shield in vulnerable areas.

The home's sunroom required a different roofing approach because of its low slope. Our crew installed new plywood decking over the existing metal roof, followed by the GAF Liberty self-adhering roofing system, using a base sheet and white cap sheet designed for low-slope applications.

Skylight & Chimney Improvements

This Crofton project also included the installation of a new VELUX deck-mounted skylight with a solar-powered blind and remote control.

We removed the existing rear skylight, resealed and reflashed the existing sun tunnels, and installed a new aluminum AirJet chimney housing with a red brick appearance.

These details were an important part of completing the roofing system and addressing areas where proper flashing and weather protection matter.

New Seamless Gutters & Gutter Guards

To finish the exterior improvements, we replaced the existing gutters with 6-inch white seamless aluminum gutters, new 3x4 downspouts, and Extreme stainless steel micro-mesh gutter guards.

The roofing work includes a 10-year AHI workmanship warranty, along with applicable GAF System Plus and manufacturer warranty coverage. The new gutter installation also includes a 10-year labor warranty.

By completing the pitched roof, low-slope sunroom roof, skylights, chimney housing, and gutters together, we were able to give this Crofton homeowner a coordinated exterior upgrade.

Rockville, MD – GAF Timberline HDZ Roof Replacement & Ventilation Improvements

In Rockville, Maryland, our team completed a full roof replacement with several important improvements to the home's ventilation and chimney flashing.

After protecting the landscaping and surrounding property, we removed the existing shingles down to the roof deck and inspected the underlying wood.

The new roofing system features GAF Timberline HDZ architectural shingles, along with ABC synthetic underlayment, ice and water protection, GAF ProStart starter shingles, Seal-A-Ridge hip and ridge shingles, and Cobra Snow Country ridge ventilation.

Improving Roof Ventilation & Chimney Protection

One of the standout details of this Rockville roofing project was the ventilation work.

We removed an existing whirlybird roof vent, closed the opening with plywood, and installed updated ridge ventilation. We also installed a new Lomanco 750 roof vent, connecting the existing ductwork so it could exhaust to the exterior.

Behind the chimney, our crew constructed a custom metal cricket, designed to help direct rainwater away from the back of the chimney rather than allowing it to collect in that area.

New chimney flashing and pipe collars were also installed to help protect these vulnerable roof penetrations.

Once the roof was complete, we cleaned the gutters, removed all roofing debris, and performed a magnetic sweep around the yard for loose nails.

The homeowner received a 10-year workmanship warranty, along with applicable GAF System Plus and lifetime material warranty coverage.

This Rockville project is a great example of why a roof replacement involves more than installing new shingles. Proper ventilation, flashing, and water management are just as important to the overall roofing system.

Waldorf, MD – CertainTeed MainStreet Siding & Seamless Gutter Replacement

Our next project brought us to Waldorf, Maryland, where we completed a full siding replacement and installed new seamless gutters.

The existing siding was removed from the entire home before our crew installed Tyvek house wrap, carefully taping the seams to create an additional layer of protection beneath the new siding.

The homeowner selected CertainTeed MainStreet vinyl siding in Natural Clay, paired with Sandstone Beige exterior accents.

We installed new J-channel, sill trim, inside and outside corners, aluminum starter strips, and matching blocks around exterior fixtures such as lights, outlets, hose bibs, and dryer vents.

To complete the finishing details, we wrapped the garage door and trim beneath the windows with Sandstone Beige aluminum coil stock.

New Gutters to Complete the Exterior

Along with the siding replacement, we removed the existing gutters and downspouts and installed new 5-inch seamless aluminum gutters with hidden screw hangers and 3x4 downspouts.

The new siding is backed by applicable limited lifetime manufacturer warranty coverage and a 5-year AHI labor warranty, while the gutter installation includes a 10-year labor warranty.

Following the project, the homeowner shared a 5-star review:

“The staff and the workmanship was outstanding.”

We always appreciate hearing from homeowners after a project is completed, especially when they recognize the hard work and attention to detail our crews put into each installation.

This Waldorf exterior renovation gave the home a refreshed appearance while improving the protective layers beneath the siding and updating the gutter system.

Gaithersburg, MD – Main House & Shed Roof Replacement with Complete New Decking

In Gaithersburg, Maryland, our team took on a roofing project that required significant preparation before the new shingles could be installed.

Unlike a standard roof replacement, this project involved removing two existing layers of shingles and replacing all of the plywood decking on both the main house and the shed.

Once the old roofing materials were removed, our crew installed new plywood decking and the necessary plywood clips. We also replaced deteriorated rake boards on the right side of the home with new pressure-treated 2x8 boards.

TAMKO Titan Roofing in Rustic Slate

For the new roofing system, the homeowner selected TAMKO Titan 50-year architectural shingles in Rustic Slate.

These shingles feature a reinforced nailing zone, specified wind coverage up to 160 MPH, and a Class 3 impact rating.

The roofing system also included ice and water shield, ABC synthetic underlayment, TAMKO starter shingles, matching hip and ridge shingles, white drip edge, and Lomanco ridge ventilation.

We installed new pipe collars and chimney flashing, removed an old satellite dish, and completed a thorough cleanup of the property.

The new roofing system includes a 10-year AHI workmanship warranty and applicable 50-year TAMKO material warranty coverage.

Replacing the decking on both structures was an important part of this project. Rather than installing new shingles over aging plywood, our team was able to provide a new foundation for the roofing system on both the house and shed.

The result was a coordinated roofing upgrade using the same Rustic Slate shingles across both structures.

Crofton, MD – GAF Timberline HDZ Roofing, Sun-Tek Skylights & 6-Inch Seamless Gutters

Our final project brings us back to Crofton, Maryland, where we completed another extensive roofing and gutter installation.

This project featured a GAF Timberline HDZ architectural roofing system with several protective components designed to work together.

The installation included Tarco LeakBarrier ice and water shield, ABC Pro Guard synthetic underlayment, GAF ProStart starter shingles, GAF Seal-A-Ridge hip and ridge shingles, and Cobra Snow Country ridge ventilation.

We also installed new pipe flashing, step flashing, and aluminum roof-edge protection.

Skylights & Low-Slope Roofing

In addition to the main shingle roof, this project included two Sun-Tek skylights and a section of low-slope roofing completed with the GAF Liberty self-adhering base and cap sheet system.

Using the appropriate roofing materials for different roof slopes is an important part of creating a complete exterior roofing system.

Approximately 225 Feet of New Gutters

To finish the project, we removed the old gutters and installed approximately 225 linear feet of new 6-inch white seamless aluminum gutters with hidden screw hangers, along with new white 3x4 downspouts.

The gutter installation includes a 10-year AHI labor warranty.

Between the new GAF roofing system, skylights, low-slope roofing materials, and oversized seamless gutters, this Crofton home received several important exterior improvements in one project.
