Home additions & dormers in Hempstead, NY
Need more bedrooms, a bigger kitchen or real headroom upstairs? A dormer or home addition gives your family the space it needs without leaving the neighborhood you love. As roofers turned general contractors, we know exactly how to tie new construction into your existing home.
Add space and value without moving
For many Nassau County families, moving means higher costs, a new mortgage rate and leaving schools, neighbors and commutes behind. Building up or out is often the smarter way to get the space you need, and it adds lasting value to your home.
Additions and dormers are where our roofing background really matters. Tying a new roofline into an existing one, flashing it correctly and matching shingles and siding is what separates an addition that looks original from one that looks tacked on and leaks. We handle the structure, roof, exterior and interior finishes as one project.

Home Additions & Dormers FAQs
What is a dormer?
A dormer is a structure that projects from a sloped roof, usually with a window, to add headroom, light and usable floor space to an attic or upper floor. Common types include shed, gable and full dormers.
Do I need a permit for a dormer or addition?
Yes. Dormers and additions require permits and approved plans. We tell you upfront what's needed and coordinate the process with the Town of Hempstead or your incorporated village.
Can you match my existing roof and siding?
Yes. As experienced roofers and exterior contractors, we take care to match shingles, siding and trim so your addition blends in with the rest of the house.
Is it cheaper to build up or build out?
It depends on your lot, foundation and layout. Building up preserves yard space, while building out can be simpler structurally. We'll walk through the pros and cons for your home during a free consultation.
Can I stay in my home during construction?
Often, yes, especially for dormers and rear extensions. We'll discuss what to expect for your specific project, including any days when access may be limited.
