Skylight Flashing: Step Flashing vs. Continuous Flashing Kits
Installing a skylight is an excellent way to bathe your interior spaces in natural light, but cutting a massive hole in your roof deck requires impeccable waterproofing. The interface between the asphalt shingles and the skylight frame is protected by a metal flashing kit. Depending on the brand and model of your skylight, your roofing contractor will use either step flashing or continuous flashing—and understanding the difference is vital for long-term leak prevention.
The Step Flashing Method
Most modern, deck-mounted skylights utilize a step flashing kit. This consists of several L-shaped metal brackets that are woven individually between each course of asphalt shingles as they run up the sides of the skylight. This "stepped" method ensures that any water running down the side of the skylight is immediately kicked out onto the top of the shingle below it. Because each piece can move independently, step flashing perfectly accommodates the natural expansion and contraction of the roof deck without buckling.
Continuous Flashing Vulnerabilities
Older or lower-end curb-mounted skylights sometimes use continuous flashing—a single, long piece of L-channel metal running the entire length of the skylight. While it is faster to install, it is far more rigid. Over time, as the house settles and the roof undergoes severe temperature swings, continuous flashing can warp or pull away from the curb. When a gap forms along a continuous run, water can easily track underneath it and rot the underlying wood. If you are replacing a roof with existing skylights, upgrading to a modern step-flashed kit is highly recommended.

The Truth About Roof Overhangs and Attic Intake Vents
When discussing attic ventilation, homeowners frequently fixate on the exhaust system—usually the ridge vent or powered attic fans. However, an exhaust vent cannot push hot air out if it cannot pull cool air in. The entire thermodynamic cycle of your roof relies on the intake vents, which are heavily dependent on the architectural design of your roof's overhangs (the eaves).
The Soffit Dilemma
Ideally, a home features wide eaves that extend 12 to 24 inches past the exterior walls. The underside of these eaves is called the soffit. In a well-ventilated roof, the soffit is covered in perforated aluminum or vinyl panels, providing massive square footage for cool, fresh air to enter the attic. This air sweeps up the underside of the roof deck, collecting heat and moisture, and exits through the peak.
Homes With No Overhangs
Many Cape Cod, Colonial, and modern minimalist homes are built with "flush eaves," meaning the roof ends abruptly at the exterior wall. Without a soffit, there is nowhere to install traditional intake vents. If your roofer simply installs a ridge vent on a home with no intake, the ridge vent will act as a vacuum, pulling conditioned air from inside your living space through the ceiling, causing your energy bills to skyrocket. To solve this, contractors must install specialized "drip-edge vents" or low-profile "fascia vents" to artificially create intake airflow at the very bottom edge of the roof.

Commercial Roof Drains: The Importance of Cast Iron Strainers
For commercial flat roofs in Hampton Roads, the internal drainage system is the central nervous system of water management. The drains located in the low points of the TPO or EPDM membrane funnel thousands of gallons of water straight through the building's interior plumbing. Protecting these drains from clogging is the single most important maintenance task a property manager can perform.
Why Plastic Domes Fail
At the top of every internal drain sits a strainer dome. In an attempt to cut costs, many building owners use cheap plastic or PVC domes. Over years of exposure to intense UV radiation, these plastic domes become incredibly brittle. A minor impact—such as a piece of hail, a dropped tool, or even a heavy seagull—can easily shatter the plastic. Once the dome breaks, leaves, plastic bags, and gravel wash directly into the plumbing, creating a massive internal blockage that often requires a costly visit from a commercial plumber to clear.
The Cast Iron Upgrade
To ensure absolute reliability, all internal commercial drains should be capped with heavy-duty cast iron strainers. These metal domes are practically indestructible. They easily withstand impacts, UV degradation, and the sheer weight of heavy, wet organic debris pressing against them during a hurricane. By ensuring your cast iron strainers are secured properly to the clamping ring, you guarantee that water can escape the roof while debris remains safely on the surface, preventing disastrous ponding and structural collapse.

Exterior Design: Choosing Siding Colors to Match Your Architectural Shingles
If you are planning a full exterior remodel, coordinating the colors of your new architectural shingles with your vinyl or fiber-cement siding is critical for maximizing curb appeal. Unlike paint, which can be easily changed, roofing and siding materials are semi-permanent fixtures that you will live with for decades. Developing a cohesive color palette ensures your Virginia Beach home looks modern and sophisticated.
High Contrast vs. Monochromatic
The most visually striking homes utilize the rule of high contrast. If you are installing crisp, white, or light gray siding, a dark "Charcoal" or "Moire Black" roof provides a beautiful, grounded anchor that draws the eye upward. This contrast highlights the architectural trim and makes the home appear larger. Conversely, if you prefer a subtle, monochromatic look, pairing deep blue or slate siding with a "Pewter" or "Estate Gray" roof creates a calming, cohesive aesthetic popular in coastal communities.
Working with Earth Tones
If your home features natural stone facades or warm-toned brick, you must avoid cool gray or blue shingles, as they will aggressively clash with the masonry. Instead, opt for "Weathered Wood," "Heather Blend," or "Burnt Sienna" architectural shingles. These blends feature multiple granular colors (browns, greens, and tans) that pull the natural, earthy elements out of the stone and brick, seamlessly blending your siding, roof, and landscaping into a unified design.

Roof Deck Fastening Codes: Preventing Wind Uplift in Coastal Virginia
During a major coastal hurricane, homeowners logically worry about the wind blowing their shingles off. However, structural engineers worry about something far more catastrophic: the wind blowing the entire plywood roof deck off the trusses. To prevent this, the Virginia building code strictly dictates exactly how OSB and plywood decking must be fastened to the underlying framing in high-wind zones.
The 8d Ring-Shank Requirement
In the past, roof decks were often attached using standard smooth-shank framing nails or heavy staples. Under extreme aerodynamic lift, these smooth fasteners could easily pull straight out of the wood. Today, codes require the use of 8d (eight-penny) "ring-shank" nails. These specialized nails feature aggressive ridges along the shaft. When driven into a wooden rafter, the wood fibers lock tightly into these rings, making the nail virtually impossible to pull out through brute force alone.
The 6-Inch Fastening Schedule
In addition to using the correct nail, contractors must adhere to a strict nailing schedule. Generally, building codes in coastal areas mandate that nails must be driven every 6 inches along the edges of the plywood panel, and every 6 to 12 inches in the field (the center) of the panel. During a professional roof replacement, if your contractor discovers your existing deck was secured with staples or smooth nails, they are legally required to re-nail the entire deck with ring-shank nails before the new underlayment can be installed.
