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.

L&L Roofing Systems LLC

Our Commercial Roofing Services in Swissvale, PA

We carefully examine all critical areas to identify potential issues before they turn into costly repairs. You’ll receive clear photos and a detailed, easy-to-understand report, so you know exactly what’s going on with your roof and can make confident, informed decisions.

We install every commercial roof to handle Swissvale’s heavy rainfall and drainage demands. The result is a durable, long-lasting roof that protects your building and reduces maintenance.

When damage is too widespread to repair, replacement becomes the only financially sound option. We strip the old system, address deck issues, and install code compliant roofing.

Seamless roof coatings create a continuous, watertight barrier over your existing roof. This added layer helps stop leaks, improve durability, and extend the life of your roof without a full replacement.

Storm damage demands immediate attention. We respond quickly to secure your roof and stop water intrusion before it reaches your equipment, inventory, or halts daily operations.

We make scheduled visits to clear drains, inspect seams, and catch early signs of wear before they turn into bigger issues. With twice-yearly service, your roof stays reliable and your warranty stays protected.

Our roofers track leaks back to their true source so we can fix the real problem, not just patch the visible damage. This approach stops recurring leaks and helps prevent further structural issues

Professional Grade Roofing Materials Built for Swissvale Businesses

Commercial PVC Membrane

Commercial PVC roofing gives Swissvale businesses strong leak protection during heavy rainstorms. Heat-welded seams are stronger than the material itself, keeping water out while resisting grease, chemicals, and exhaust common in restaurants and light industrial buildings. The reflective surface also helps reduce summer cooling costs.

Closed Cell Spray Foam

Spray foam roofing is ideal for older Swissvale buildings with gaps, cracks, and uneven surfaces. It expands to seal hard-to-reach areas, creating airtight insulation that cuts heating costs during cold Pittsburgh-area winters while reducing future leak points.

Reinforced Membranes

Reinforced membranes are built for durability in tough local conditions. The embedded fabric prevents small damage from spreading, stays flexible through freeze-thaw cycles, and stands up to foot traffic from HVAC maintenance without cracking.

Heat-Welded TPO Roofing

TPO roofing delivers reliable, cost-effective protection for offices and retail spaces. Permanently bonded seams block water even when ponding occurs after storms, and the white reflective surface helps control heat buildup and UV exposure.

Metal Roof Restoration Coatings

Metal roof coatings extend the life of aging commercial roofs across Swissvale. Elastomeric coatings seal rust, seams, and exposed fasteners, then expand and contract with seasonal temperature changes. They improve energy efficiency while avoiding the cost and disruption of a full roof replacement.

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

If you’re planning commercial roofing work in Swissvale, PA, a permit is required before construction begins. The borough enforces Pennsylvania’s Uniform Construction Code through the Swissvale Borough Fire Department, and non-permitted work can lead to costly delays and penalties.

Most commercial roofing projects require approval, including full roof replacements, new roofing systems, metal roof restoration or coating applications, waterproofing repairs, and any work involving more than 32 square feet of roof decking. If the project affects drainage, weatherproofing, or structural performance, a permit is typically mandatory.

Application Requirements, Fees, and Review

Permit applications must include detailed scope drawings, contractor license and insurance, roofing material specifications, and engineering calculations when structural changes are involved. Incomplete or incorrect submissions are the most common cause of permit delays.

Permit fees and review timelines vary based on project size and complexity. Requirements should be confirmed with the Building Inspector before work begins. Commercial roofing projects require progress and final inspections, including building inspections by CEA Code Enforcement Associates, electrical inspections by the borough’s electrical inspector, and plumbing inspections through the Allegheny County Health Department.

Where and How to Apply

Permit forms must be downloaded from the borough website and submitted in person or by mail to the Swissvale Borough Fire Department at 7560 Roslyn Street, Swissvale, PA 15218. Swissvale does not offer online permit submission.
