When your existing torch down roof starts to blister, split along the seams, or pool water after every storm, you are looking at more than a cosmetic problem. Those symptoms point to a membrane that has reached the end of its service life, and patching alone rarely restores the waterproof barrier your flat or low-slope roof depends on. A full torch down roofing replacement gives you a fresh, monolithic surface that can stand up to the punishing heat, ultraviolet exposure, and sudden downpours that define our desert climate. As a Las Vegas based family owned company with over 20 years of experience, The Roofing Company handles this work from tear-off through final inspection.
Signs It Is Time to Replace Your Torch Down Roof
Modified bitumen roofs are tough, but they do not last forever. Once the granular top layer wears away and the asphalt underneath oxidizes, the membrane becomes brittle and loses its flexibility. Small cracks turn into open seams, and water finds its way into the insulation and decking below. When we inspect a failing torch-down roofing system, we look for a few telltale conditions.
- Alligatoring: a cracked, scaly surface that shows the membrane has dried out and lost elasticity.
- Standing water: ponding that lingers more than 48 hours and accelerates deterioration.
- Open or lifted seams: areas where the torch-welded laps have separated and allow moisture intrusion.
- Interior staining: water marks on ceilings or walls that confirm the leak has already reached the structure.
When several of these signs appear together, replacement is almost always more cost-effective than repeated repairs. A new 2-ply modified bitumen system resets the clock and gives you a warrantied, watertight roof.
Our Torch Down Replacement Process
We approach every re-roofing project methodically because shortcuts on a flat roof lead to leaks. Our crews are trained in proper torch application, fire-watch protocols, and the safety guidelines that protect your property and our employees. Below is the sequence we follow on a typical torch down roof replacement.
- Tear off: we remove the old modified bitumen down to the deck and dispose of the debris responsibly.
- Deck inspection: we check for rot, soft spots, or damaged sheathing and make repairs before anything else goes down.
- Base sheet installation: we mechanically fasten or adhere a base ply to create a stable foundation.
- Cap sheet torch application: we heat-weld the granulated cap sheet, fusing the laps into a continuous, waterproof surface.
- Flashing and detailing: we seal all penetrations, edges, and transitions where leaks most often begin.
Because a 2-ply system combines a base layer with a cap layer, it delivers redundant protection. Even if the top sheet is ever compromised, the base ply continues to keep water out while repairs are made.
Commercial and Residential Torch Down Applications
Torch down roofing serves a wide range of buildings across the valley. On commercial properties, flat roofs cover warehouses, retail centers, restaurants, and office buildings where foot traffic, rooftop equipment, and long spans demand a rugged surface. Commercial torch down replacement lets business owners keep their operations protected without the frequent maintenance that older built-up roofs require. The granulated cap sheet also reflects a portion of the sun’s energy, which helps reduce cooling loads during our long summers.
Residential torch re-roofing is equally valuable for homes with flat or low-slope sections, patio covers, and modern architectural designs. Homeowners appreciate that modified bitumen bonds tightly to the deck and resists the wind uplift that can peel back lesser materials. Whether we are re-roofing a single-story home or a multi-building complex, The Roofing Company brings the same attention to detail and the same commitment to durable results.
Technical Specifications That Matter
Modified bitumen membranes are engineered with polymer modifiers such as APP or SBS that improve flexibility and heat resistance. The torch application melts the asphalt backing so it flows into every contour of the substrate, creating a bond no adhesive can match. Cap sheets typically range from 160 to 250 mils in thickness, and the mineral granules add both ultraviolet protection and fire resistance.
