Benefits of Velux Skylights
Modern Velux skylights transform living spaces by maximizing natural light, reducing energy costs, improving indoor air quality, and enhancing architectural appeal.
Enhanced Natural Lighting
Velux skylights flood interior spaces with up to 30% more natural light compared to standard vertical windows. Natural daylight streams directly from above, reaching deeper into rooms and illuminating dark corners that traditional windows can't reach.
Our premium Velux installations feature advanced glass coatings that diffuse sunlight evenly throughout the space while blocking harmful UV rays. This balanced lighting creates an inviting atmosphere and reduces the need for artificial lighting during daylight hours.
Improvement in Energy Efficiency
Velux skylights contribute significantly to energy savings through passive solar heating and natural cooling. During winter months, solar heat gain helps warm interior spaces naturally, reducing heating costs by up to 10%.
The double-pane, low-E glass construction provides excellent insulation against heat loss. Advanced weather sealing and thermal breaks prevent air leakage and maintain consistent indoor temperatures.
Increased Ventilation and Air Quality
Electric venting skylights create effective air circulation by releasing stale air and drawing in fresh oxygen. The chimney effect pulls out humidity, cooking odors, and indoor pollutants through natural convection.

Remote-controlled operation allows easy ventilation management. Rain sensors automatically close the skylight at the first sign of precipitation.
Elevated Home Aesthetics
Velux skylights add architectural interest and contemporary appeal to both interior and exterior spaces. The sleek frames and expansive glass create dramatic focal points that enhance room designs.
Strategic placement can highlight architectural features or create stunning light wells in hallways and staircases. The added dimension of overhead glazing brings sophistication to any room.

FAQs
TPO roofing installations come with many common questions from our customers. We've gathered the most important information about costs, durability, brands, and maintenance to help you make informed decisions.
What are the factors influencing the cost of a TPO roof installation?
Several key elements affect TPO roofing costs. The size of your roof is the primary factor, as larger areas require more materials and labor.
The thickness of the TPO membrane impacts pricing significantly. We offer options ranging from 45 mil to 80 mil thickness, with thicker membranes costing more but providing enhanced durability.
Your roof's complexity matters too. Buildings with multiple penetrations, HVAC units, or unusual shapes require more detail work and flashing.
Accessibility affects labor costs. If your roof is difficult to reach or requires special equipment, this will increase the installation price.
How long does a TPO roof typically last under normal weather conditions?
TPO roofs installed by Washington DC Roofing Company typically last 20-30 years with proper maintenance. This lifespan depends on several factors including membrane thickness and local climate conditions.
The quality of installation significantly impacts longevity. Our certified installation team ensures all seams are properly welded and details are correctly finished.
Modern TPO formulations have improved UV and heat resistance compared to earlier generations. This enhancement helps maintain reflectivity and structural integrity over time.
Regular inspections can help identify and address small issues before they compromise the roof's lifespan.
Which TPO roofing brand shows the highest performance and reliability?
We primarily install GAF and Firestone TPO systems due to their consistent performance records and extensive warranties. These manufacturers have refined their formulations over decades.
GAF EverGuard TPO offers excellent heat and UV resistance with their advanced material science. Their products perform exceptionally well in Washington DC's varying climate conditions.
Firestone UltraPly TPO provides superior puncture resistance and flexibility, maintaining performance through seasonal temperature changes. Their seam strength is among the industry's best.
Both brands offer comprehensive warranty options that can extend up to 30 years when installed by certified contractors like us.
Are there any notable drawbacks when using TPO roofing for commercial buildings?
Installation quality is critical with TPO systems. Poorly welded seams can lead to leaks and premature failure, which is why we invest in ongoing training for our installation teams.
Some older TPO formulations had issues with premature aging and cracking. Today's improved materials have largely resolved these concerns, but choosing a quality manufacturer remains important.
TPO can be punctured by sharp objects, making regular roof inspections necessary. We recommend establishing maintenance protocols after installation.
While highly energy efficient, TPO's initial cost may be higher than some traditional roofing systems, though this is typically offset by energy savings over time.
Can a TPO roof be installed over an existing roofing system, and what are the considerations?
Yes, in many cases we can install TPO over existing roofing, potentially saving on removal costs and reducing landfill waste. This approach is called a "recover" installation.
The existing roof must be structurally sound and relatively dry. We conduct moisture scanning to detect any trapped water that could compromise the new system.
Building codes typically limit commercial buildings to two roof layers. We'll verify local regulations and assess your current roofing situation during consultation.
Proper preparation may include adding recovery board insulation to create a smooth, compatible surface for the new TPO membrane attachment.
