We had such a great experience with L&L Doors and learned that Elmer’s son(s) also own L&L Roofing Systems. If the roofing company is anything like the quality, professionalism, and pride we experienced with this family, they’re definitely worth recommending! We love supporting family-owned businesses, and it’s clear that hard work and quality craftsmanship run in this family. Wishing L&L Roofing Systems continued success!

I can't say enough good about the entire L&L team. They put a high quality roof on our flat roof office building about 6 years ago and when they came for the yearly inspection they found severe hail damage from a storm. It was a complicated process mainly due to the insurance adjuster, but Josh greatly assisted me in speaking with the adjuster many times advocating for the full and complete replacement to be paid for, and he helped me to understand all involved with multiple aspects of the job. Wendell helped to coordinate the various steps in the installation of the flat roof, shingles portion, portico and gutters, and was very helpful asking where the vehicles, dumpsters, trailers and tools could be placed at a busy office building prior to the arrival. The men worked hard in extreme heat and even some in hard rain. They left the job site impeccably clean each night. They literally were running to keep a steady pace of their hard work. There was one issue and Wendell was there within 40 minutes of my call working to resolve the situation, and it was fully resolved. They should give seminars on how work should be completed from step 1-100. I could not be more pleased with the L& L Roofing team.

We had an intermittent leak in our rubber roof that I had several people attempt to repair. L&L came out promptly and sealed all potential leak spots. We have had several extreme rainstorms since their repair, and the leak is fixed! Thanks a bunch!

We have used them at several of our locations for a variety of roof situations. Top 4 things I loved: 1) Reliable service – they showed up on time every day and finished the job as promised. 2) Responsive communication – they answered my calls quickly and kept me updated throughout the commercial roof replacement. 3) High quality workmanship – the new roof looks great and the material feels solid. I hired L and L Roofing Systems for a flat roof repair on our building and was impressed by their punctuality and professionalism. Iwould recommend them to anyone looking for a commercial roofing contractor. 4) These are genuinely friendly and down to earth people.

I had a great experience with L and L Roofing Systems. The price was fair, the crew was professional and responded quickly to my calls. They showed up right on time, worked neatly and left the job site clean. I especially appreciated how they handled my commercial roof repair with no hassle. They have done multiple roof coatings. Always prompt and professional.

Commercial Roofing Services for Bellevue Businesses

Our commercial roof inspection gives Bellevue business owners a clear picture of their roof’s condition. We document problem areas with photos and provide a written report showing what needs attention now and what can be planned for later.

We install commercial roofing systems based on your building, budget, and energy goals. Our team plans around site access, material staging, and your business hours so work stays organized and disruption stays low.

When repairs are no longer enough, roof replacement gives Bellevue businesses a chance to stop spending on recurring problems and move to a more dependable system. We help you decide whether replacement is necessary, then complete the work with careful planning and a final quality check.

Roof coatings and restoration are a smart option for commercial roofs that are aging but not ready for replacement. Our coatings help seal out moisture, extend roof life, reduce tear-off waste, and limit disruption to your business. They also perform well in Bellevue’s wet weather and changing temperatures, and reflective coatings can help lower cooling costs.

We provide emergency response for storm damage and urgent roofing problems, including temporary protection when full repairs cannot be completed right away. Fast action helps limit water intrusion, protect interiors, and reduce business disruption.

In Bellevue’s wet, cold climate, regular maintenance helps catch roofing problems early before they turn into leaks or costly repairs. Our annual or bi-annual service includes inspections, leak checks, drainage review, gutter cleaning, and sealant or coating touch-ups as needed.

We handle patch work and leak repairs to stop water entry, slow roof deterioration, and help Bellevue businesses avoid larger repair costs later.

Do I Need a Permit for Commercial Roofing in Bellevue, PA?

Many commercial roofing projects in Bellevue need borough review before work begins. In Bellevue, permits are required for repairs, alterations, additions, and similar work on existing buildings. For commercial projects, applications must be submitted to Bellevue first, and third-party plan review is part of the process.

Because permit requirements depend on the scope of the work, it is best to check early before the project is scheduled. That helps avoid delays and keeps the job moving once work is approved.

We Do It For You

We make the process easier by inspecting the roof, documenting the issues, explaining your options, and giving you a clear proposal. Once the project is approved, we coordinate the work and keep the job moving with as little disruption to your business as possible.
