Washington DC Flat Roofers

Choosing the right roofing materials for your home in DC.

Not every roofer is a flat roofer. This is because flat roofing requires special training and tools. We are Washington DC flat roofers that know how to do the job right. In Washington DC most roofs are flat roofs due to the prevalence of rowhouses and modern commercial buildings, which benefit from the additional interior space that flat roofs provide. Flat roofing, typically made from materials like torch-down roofing, modified bitumen, or EPDM rubber, require skilled waterproofing and specialty tools to prevent leaks from the region's frequent rain. Asphalt shingled roofs, though less common in D.C., are still found on some residential buildings and offer durability against seasonal changes.

If you looking for a good roofer, good news you found the right roofing company in DC. There is a reason not many contractors work in DC due to it's traffic, difficulty of install with cumbersome materials, but the good news is that we have the experience to get the job done right.

Washington DC Siding Installation

How to choose between vinyl or fiber cement siding?

When it comes to Siding Installation in Washington DC, fiber cement and solar defense vinyl siding are both top choices, each with its own benefits.

James Hardie Fiber Cement is durable and resilient to the area’s crazy weather, humidity, temperature fluctuations and even fire hazards. It looks like traditional wood which is perfect for preserving the historic look of many DC neighborhoods.

Vinyl siding is more affordable and low maintenance, comes in many colors and styles. It resists moisture well for DC’s humid summers, but not as durable in extreme weather as fiber cement.

Both have good insulation and curb appeal, it’s all about budget and look.

Replacement Windows

Are there tax credits for replacement windows in Washington, DC?

Yes, Washington, DC residents may be eligible for tax credits and incentives to help offset the cost of new window installation in Washington DC if the new windows are energy efficient.

Here are some common tax credits and programs that may apply:

Federal Residential Energy Efficient Property Credit:
The federal government offers a tax credit for energy efficient home improvements including windows that meet ENERGY STAR® requirements. For windows installed between 2023 and 2032 this credit covers 30% of the cost up to $600 per year. To qualify windows generally need to be ENERGY STAR® certified meaning they help reduce home energy use especially for heating and cooling.

If you’re considering a window replacement check the specific eligibility requirements and consult a tax advisor to make sure you take full advantage of any credits or rebates that apply to your project.

Front Door Installation Services

Front door styles and options guide.

In Washington, D.C. you have many options for front doors especially when considering historic preservation or security.

Historic and Custom Doors
If your home is in a historic district, door replacements need approval to match the original style. Custom wood doors or reclaimed doors are popular choices that fit historic looks.

Fiberglass Doors
Fiberglass doors are energy efficient, low maintenance and versatile in design. They can mimic wood grain or be painted to match historic guidelines, a durable alternative to wood.

Security Doors
Steel and iron doors provide added security with styles that can fit historic looks. Fiberglass doors with reinforced cores or multi-point locking systems also offer high security without the traditional security door look.

Permit and Tax Incentives
Door replacements in historic districts need Historic Preservation Office approval. Both window and door installations in Washington DC qualify for energy efficiency rebates on select door upgrades, so that helps with the cost. Choose the right door and you’ll enhance both the style and security of your D.C. home.

Deck Installation in Washington DC

Considerations for your deck installation in Washington DC.

A few considerations your deck builder in Washington DC should know:

‍Permits and Regulations: Most decks require a permit from DCRA, and additional approvals if in a historic district. Zoning rules apply to height and property line setbacks.

‍Weather Durability: Choose weather resistant materials like composite or treated wood and weatherproof finishes for DC’s climate.

‍Design and Functionality: Choose a deck size and layout that fits your lifestyle and style that matches your home especially if in a historic area.

We will build you a deck that is compliant, durable and meets your needs and DC regulations.

Seamless Gutters and Gutter Guards

Historic gutter features or seamless gutters in DC.

Seamless Gutter installation in Washington DC can match architectural details and historic charm:

‍Seamless Gutters: These custom gutters have a clean look that goes with historic facades. Copper seamless gutters, in particular, develop a patina over time and add character to row houses and brownstones.

‍Half-Round Gutters: Seen on traditional or historic homes, half-round gutters add elegance and go with period architecture. They’re made from copper or aluminum and fit well with colonial and Victorian styles found in D.C.

‍Decorative Downspouts and Brackets: For extra architectural detail consider ornate brackets, straps or decorative downspouts that add both form and function especially in historic neighborhoods.
‍Custom Finishes: Specialty finishes or colors can match your home’s trim or other metalwork so you can maintain architectural consistency especially where historic preservation is a priority.

These gutter styles and details match D.C.’s architectural character and historic integrity.

Roofing Contractors in Washington DC

Roofing in Washington DC is different than the suburbs.

Roofing in DC is tough due to the urban density and strict permitting. Access to many buildings especially in older neighborhoods is difficult because of narrow streets, limited parking and tight spaces between buildings. Transporting materials and equipment to job sites is a logistical challenge. DC has strict building codes and historical preservation requirements especially in areas with landmarks or row houses so planning and approval processes are extensive. Roofing contractors have to navigate these regulations to get the permits which can add to the timeline and cost. All these factors make roofing in the nations capital more complicated than many other areas.

Local Testimonial from Washington, DC

"Lance and the team were great. We replaced the entire roof and it was completed professionally and efficiently over a two day span. With the harsh storms we’ve been having, I have peace of mind knowing that there will be no leaking inside of the house."
