Roof Installation in Windham, ME and Across Maine
Professional installation of new roofs using high-quality materials.

A new roof is one of the biggest investments you will make in your home, and in Maine it has to handle ice, wind off the water, heavy snow load, and long stretches of freeze and thaw. Spartan Roofing LLC installs complete roof systems for homeowners, builders, and business owners across the state, working out of Windham and traveling anywhere in Maine.
We install architectural asphalt shingles, standing seam and ribbed metal panels, and low slope systems for additions, garages, and light commercial buildings. Every installation starts with the deck. If we find soft or rotted sheathing once the old surface is off, we show you the damage, explain the options, and replace what needs replacing before anything new goes down.
Underneath the surface we install ice and water shield along eaves, valleys, and penetrations, synthetic underlayment across the field, new drip edge, and properly sized ventilation. That layered approach is what keeps ice dams from pushing water back under the shingles in February, and it is the part of the job most people never see.
New construction work is a regular part of what we do. We coordinate schedules with builders and general contractors so the structure gets dried in on time, and we keep the site clean between phases. For homeowners, we handle permits where required, protect landscaping, run a magnet over the yard and driveway at the end of each day, and haul all debris away.
Pricing is straightforward. We measure the roof, walk you through material choices with real samples, and give you a written estimate with no pressure attached. If a repair would serve you better than a full installation, we will tell you that too.

Roof Installation Questions
- How long does a new roof installation take?
- Most Maine homes are done in one to three days depending on size, pitch, and how much deck repair we find. Larger or steeper roofs and metal installs can take longer.
- What is the best time of year to install a roof in Maine?
- Late spring through fall is ideal because shingles seal best in warmer weather, but we install year round and adjust methods for cold weather work.
- Do you install metal roofs as well as shingles?
- Yes. We install both, and we will walk you through the cost, snow shedding, and lifespan differences so you can decide what fits your home and budget.
- Will you replace rotted roof decking?
- If we find rot or soft spots, we show you the area, quote the sheathing replacement before we proceed, and document the repair with photos.
