Commercial Roofing FAQ (Part 2)

SPF is a liquid-applied foam that expands into a solid, seamless surface. It provides the highest R-value for insulation and is excellent for complex roofs with many penetrations.

Infrared cameras detect heat signatures. Since wet insulation holds heat longer than dry areas, we can "see" moisture trapped under the membrane at night, allowing for targeted repairs.

Silicone coatings are high-solids liquid membranes applied over existing roofs. They are highly UV-resistant and, unlike acrylics, will not degrade under ponding water.

A ballasted roof uses a membrane that is not fastened or glued but held in place by weight—usually large river stones or concrete pavers.

ELD uses low-voltage electricity to find breaches in a membrane. It is 100% accurate and often used to test new installations before they are finalized.

A scupper is an opening in the side wall (parapet) of a roof that allows water to drain off into a downspout. It acts as a primary or secondary drainage point.

Internal drains move water through the center of the building into the sewer system, preventing massive amounts of water from pouring off the edges and eroding the foundation.

A curb is a raised metal frame that acts as a pedestal for heavy HVAC units. It allows the roof membrane to be flashed upward, ensuring the unit doesn't become a leak source.

Tapered insulation is sloped foam board used on flat roofs to create an artificial grade, directing water toward the drains to prevent ponding.

These are backup drains set 2 inches higher than the main drains. If you see water coming out of an overflow pipe, it means your main drains are clogged.

Yes. Hail often causes "bruising" or fractures on the underside of the membrane that aren't visible from the top but will eventually lead to leaks.

It is a temporary waterproofing measure using heavy-duty tarps or specialized patches to protect the building interior immediately after storm damage.

Wind creates a vacuum at the edges of the roof. If the perimeter metal (fascia) isn't properly secured, the wind can peel the entire membrane off the deck.

This occurs when a roof's temperature drops 50+ degrees in minutes (like a cold summer storm). The rapid contraction can pull seams apart or split older membranes.

Take clear photos of the damage, any interior leaks, and debris on the roof. Keep the dates of the storm event and call a professional roofer for a detailed report.

It is a long-term strategy that tracks the condition, repair history, and remaining life of your roof, allowing you to budget for replacement years in advance.

An NDL warranty is a manufacturer guarantee that covers the full cost of labor and materials for a repair, regardless of how much those costs increase over time.

Under Section 179, many businesses can deduct the full cost of roof repairs or replacements in the year they are completed. Consult your tax advisor for specifics.

A new, warrantied commercial roof is a major selling point that reduces the buyer's risk, often allowing you to increase the asking price of the property.

Most manufacturer warranties are transferable, though they often require an inspection and a transfer fee within 30 days of the property sale.

In most cases, no. We coordinate with you to manage noise and foot traffic so your business can remain operational during the project.

We use specialized vacuum systems or protective sheeting inside the building to catch dust and debris if the roof deck has gaps or is being replaced.

Walkway pads are thick, reinforced rubber sheets installed in high-traffic areas (like the path to HVAC units) to prevent technicians from puncturing the roof.

Yes, for businesses like retail centers or hospitals where daytime noise is prohibited, we can schedule crews for night-shift installations.

A core sample is a small circular cut made through all layers of the roof. It tells us the type of insulation, how many roof layers exist, and if moisture is trapped inside.

This is a meeting between our project manager and your team to discuss the timeline, safety protocols, and staging areas before any work begins.

We provide on-site dumpsters and remove all debris daily. We also prioritize recycling materials like metal, wood, and certain membranes.

It ensures you are 100% satisfied with the work, confirms all debris has been removed, and allows us to verify that all flashings and drains are perfect.

We use specialized flashings called "boots" or "pitch pockets" that are sealed and clamped to ensure water cannot enter where pipes pass through the roof.

This is when the roofing membrane is secured to the roof deck using screws and plates rather than adhesives. It is very common and extremely durable.

A cool roof is a highly reflective surface (usually white TPO or PVC) that stays significantly cooler than traditional dark roofs, lowering your energy bills.

Yes! TPO is one of the best surfaces for solar because its reflective properties keep the panels cooler, which actually makes them more efficient.

A green roof is a waterproofed roof covered with soil and plants. They provide incredible insulation and help manage stormwater in urban areas.

Only if not done correctly. We ensure that any solar mounting system is properly flashed and approved by the roof manufacturer to keep your warranty intact.

These are high-performance skylights that diffuse sunlight to brighten large warehouses, allowing you to turn off electric lights during the day.

OSHA requires safety harnesses, guardrails, or safety monitors on all commercial projects to protect workers from falls. We strictly adhere to these federal laws.

It is a rating that measures how much wind force a roof can withstand. We design our roofs to meet or exceed the local building code for your specific area.

Yes. Beyond general liability, we carry workers' comp and specialized "open roof" coverage to protect your property during the installation process.

Most commercial buildings require a Class A fire rating, which means the roofing system is highly resistant to fire spreading from the outside.

We use specialized pipe supports that allow the lines to sit above the roof surface and move slightly with thermal expansion without damaging the membrane.

A parapet is a low wall that extends above the roofline. It must be properly waterproofed (flashed) and topped with a metal "coping cap."

Buildings move as they heat up and cool down. We use expansion joints and flexible membranes to ensure the roof doesn't crack as the building shifts.
