Flat Roof Systems for Southern Maine Businesses
A commercial roof rarely gives you the luxury of forgetting about it. When everything works, it protects inventory, equipment, employees, tenants, and the building’s day-to-day operations. When something goes wrong, even a relatively small leak can become a problem that reaches well beyond the roof.
For dependable York County commercial roofing, businesses and property owners can turn to LJ & Company. Based in Wells, Maine, our team installs and services EPDM and TPO membrane roofing systems for commercial buildings throughout Southern Maine. We take the time to look at the complete roof, not just the spot where water happened to show up inside.
Whether you are dealing with an aging flat roof, recurring leaks, drainage concerns, or planning a new membrane installation, we can help you understand what the roof needs and what your options are.
Drainage, insulation, penetrations, and existing layers
EPDM or TPO, fastening method, edge metals, tapered insulation
Manufacturer-spec prep, seam integrity, curb and penetration detailing
Water test where appropriate, final inspection, maintenance plan
We propose the right membrane, details, and warranty for your building. Contact us today to learn more about our commercial roofing services.
A proven black rubber membrane known for toughness and flexibility. Great for buildings that value long service life and simple maintenance.
Best when: You want a time-tested system and don’t need a reflective white surface.
A white, heat-welded membrane that reflects sunlight and helps manage cooling loads. Clean seams, sharp detailing, and efficient installs.
Best when: Energy savings and bright, reflective surfaces are priorities.
A commercial roof in York County has a demanding job.
Summer sun heats the membrane. Heavy rain tests drains and seams. Then winter brings freezing temperatures, snow, ice, and repeated freeze-thaw cycles. Coastal properties may also have strong winds and weather coming in from the Atlantic.
That makes the details especially important.
LJ & Company installs commercial roofing with the entire system in mind. During an assessment, we review drainage, insulation, penetrations, existing roofing layers, and the roof’s overall condition. From there, we can recommend an EPDM or TPO system along with appropriate fastening, edge metal, and insulation details for the building.
A membrane is only one part of a commercial roof. How you install that membrane around drains, curbs, walls, vents, HVAC equipment, and roof edges can make just as much difference over time.
EPDM has been used on commercial and low-slope roofs for decades, and for good reason.
It works.
EPDM, or ethylene propylene diene monomer, is a flexible rubber roofing membrane known for toughness and straightforward maintenance. LJ & Company recommends EPDM when a building owner wants a time-tested commercial roofing system and does not specifically need a white reflective surface.
Its flexibility can be especially useful in climates where temperatures range from hot summer days to freezing winter conditions.
EPDM may be a good fit for:
The right system still depends on the roof itself. Before choosing a membrane, consider existing materials, insulation, drainage, roof layout, and other conditions.
That is why we start with an assessment rather than assuming one roofing material fits every building.
TPO takes a different approach.
This single-ply commercial roofing membrane typically has a bright white surface that reflects sunlight rather than absorbing as much solar heat as a dark roof. Its seams are heat-welded to form a continuous roofing surface.
LJ & Company installs TPO for commercial property owners who want a reflective roof with clean seam detailing and efficient installation.
It is often worth considering when cooling loads and heat gain are concerns.
That does not mean TPO is automatically better than EPDM. The two systems have different strengths, and the building itself should drive the decision.
If you are not sure which one makes sense, you do not have to figure it out before calling us. We can look at the roof and explain the practical differences.
Not always.
Water has a habit of traveling.
The damp ceiling tile in the back office may be several feet from where water enters the roofing system. Water can follow insulation, decking, beams, or other components before it finally becomes visible inside.
That is why finding a commercial roof leak takes more than looking directly above the puddle.
During an inspection, we look for signs of problems around seams, penetrations, drainage areas, roof edges, curbs, flashing, and other vulnerable locations.
If the roof can be serviced rather than replaced, that’s worth knowing.
LJ & Company’s approach is to assess the problem, explain the available options, and provide a clear written scope rather than pushing every customer toward the same solution. The company offers free inspections or estimates and outlines the proposed materials, timeline, and pricing before work begins.
Commercial roofs may look flat from the parking lot, but water still needs somewhere to go.
Poor drainage can leave water sitting on sections of the roof after a storm. Over time, those wet areas can expose weak points in seams, flashing, penetrations, and the membrane itself.
Snowmelt creates another challenge in Maine. During periods of warming and refreezing, water needs a clear path toward the roof’s drainage system.
This is one reason LJ & Company evaluates drainage and tapered insulation as part of commercial roof planning. Tapered insulation can be incorporated where appropriate to help direct water toward drains and other intended outlets.
The roof needs to do more than keep rain from passing through the membrane. It needs to manage where that water goes afterward.
Definitely.
Commercial rooftops can get crowded.
There may be vents, HVAC equipment, pipes, drains, curbs, exhaust systems, and other equipment interrupting what would otherwise be one continuous roofing surface.
Each one creates another detail that has to be handled correctly.
We also pay close attention to these areas when servicing an existing roof. A membrane may still be in reasonable condition overall while a penetration or edge detail has begun causing trouble.
Careful detailing here can mean the difference between a dry building and a recurring leak that returns every time a hard rain moves through York County.
Roof work is disruptive enough. Business owners should not have to wonder what is happening next.
Our commercial process starts with an assessment. We look at the existing roof, drainage, insulation, penetrations, and other conditions that may affect the project.
Then we develop the system.
That may include EPDM or TPO, the fastening method, edge metals, insulation, and the details necessary around rooftop features. Installation follows manufacturer specifications, with particular attention paid to seam integrity and penetrations. LJ & Company completes the process with final quality-control checks and discusses ongoing maintenance needs.
The idea is simple: understand the roof before work begins and clarify the scope.
For a business owner trying to schedule roofing around employees, customers, deliveries, tenants, or daily operations, that planning matters.
York County includes everything from busy coastal communities to inland towns, and commercial properties are just as varied.
A retail building in York may have very different roofing concerns than a commercial property in Wells, an apartment building in Biddeford, or a facility farther inland in North Berwick.
LJ & Company is based at 956 Burnt Mill Road in Wells and serves Southern Maine communities throughout the surrounding region. Its service area includes Wells, Kennebunk, Biddeford, Saco, York County, and other nearby communities.
Being local also means understanding the conditions these roofs face.
We know Maine weather doesn’t politely wait until a convenient week to test a roof.
Commercial roofing is not a place for vague estimates and unclear expectations.
LJ & Company was founded in 2021 and has built its approach around straightforward pricing, clear communication, professional crews, and organized project planning. The company provides both residential and commercial roofing services throughout Southern Maine.
For commercial roofing, that means looking beyond the membrane itself.
We consider:
You should understand what is being installed on your building and why.
We are happy to explain it.
If your commercial roof is leaking, showing its age, or leaving you wondering how much life it has left, waiting for the next major storm usually doesn’t make the decision easier.
