Why pair windows with roofing work
Roofs and windows are both part of the envelope that keeps water out of a house. When the original windows on an Ashburn home are as old as the original roof, it can make sense to plan both at once: one contractor, one written scope, and one round of HOA paperwork instead of two. It also lets us look at the places where they interact, such as dormer windows that sit inside a roof plane or windows directly below a roof-to-wall intersection.
What window replacement includes
- Replacement window installation alongside roofing or exterior work
- Material and style selection
- Removal of the existing windows
- Flashing and sealing for weather protection
Flashing and sealing are where window jobs succeed or fail. A window that is not integrated with the weather barrier around it can let water into the wall, where it may not show for a long time. We treat window flashing with the same care as roof flashing.
HOA review for windows in Ashburn
Window color, grid pattern and style are visible from the street, so many Ashburn associations want to review them. Ashburn Village, for example, states that exterior changes to single-family homes and townhomes require association approval before installation. Requirements vary by community, so check your own association's guidelines before you order windows, and ask us for the product details you need for the application.
Dormers and windows near the roof
Many Ashburn homes have dormers or second-floor windows that sit just above a lower roof. When we replace a roof, we pay close attention to the flashing where those walls meet the roof, and if the windows in those walls are due, replacing them in the same project avoids disturbing new flashing later. The photo below shows a dormer during a re-roofing project in Reston, not Ashburn, with new underlayment going on around it.
Planning the order of work
When windows and a roof are both on the list, the order matters. Windows in a wall that meets the roof are easiest to replace before or along with the roof, so the new step flashing and counter-flashing are not disturbed afterward. Windows elsewhere on the house can usually be scheduled independently. We lay out the sequence in the written scope so you know what happens when, and so a single HOA application can cover everything that changes on the outside of the house.
If you are only replacing windows, we can still help, though our focus is on window replacement as part of roofing and exterior projects. Tell us what you have in mind when you request an estimate and we will be clear about whether it is a good fit.
Kenney Construction is licensed, insured and bonded in Virginia (DPOR #2705187519), and the same company handles window work that handles the roof, so there is one point of contact for the whole exterior project.
