Upgrade Your Roof with a Stylish Dormer
Are you looking to enhance your home’s roof and create more space? Consider adding a dormer. A dormer is a protrusion from the sloped side of your existing roof that not only increases natural light but also provides additional overhead room. At Daniel R. O’Brien Contracting LLC, we specialize in reinventing roofs with stylish dormers.
Our team will take care of every aspect of the project for you, starting from designing the dormer and completing all necessary drawings to obtaining permits. Rest assured, all our constructions are done in compliance with building codes. With us, you can sit back and relax, knowing that your dormer project is in capable hands.


Why Add a Dormer to Your Home?
- Additional Light: A dormer brings in more natural light, making your home a brighter and more welcoming space.
- Improved Ventilation: By adding an operable window, a dormer can enhance the ventilation in your home, ensuring fresh air circulates effectively.
- Increased Living Space: Dormers can transform your underutilized crawlspace or attic into a functional area. The additional square footage can be used for a reading nook, sleeping area, expanded storage, or any other creative purpose you desire.
- Upgraded Curb Appeal: Not only do dormers provide functional benefits, but they also enhance the aesthetic appeal of your home’s exterior. They add a touch of charm and character that can elevate your home’s overall look.
Various Dormer Styles
We offer a range of dormer styles to suit your preferences and complement your home’s architecture.
- Bonnet Dormer: This style features a curved roof surrounded by vertical walls on either side of the window, creating an elegant bonnet shape.
- Eyebrow Dormer: With a gentle, curved, and wave-like design, the eyebrow dormer adds a unique and whimsical touch to your roofline.
- Gable Dormer: The gable dormer is the most popular choice, characterized by its triangular shape that slopes evenly, seamlessly blending with the existing roof.
- Hipped Dormer: This type of dormer has three roof planes that slope upward and converge at a central point above your roof’s peak, adding a distinctive architectural element.
- Shed Dormer: Perfect for creating a flat, squared-off space, the shed dormer has a lower pitch than the rest of the roof, providing ample headroom and versatility.
