Will replacing my commercial roof disrupt my business?

It shouldn't. A professional commercial roofing contractor will work with you to stage materials safely, schedule loud tear-off work during off-hours if necessary, and ensure your daily operations and customer access are not interrupted.

How often should a commercial roof be inspected?

Commercial roofs should be inspected twice a year (spring and fall) and immediately after any severe weather event. Preventative maintenance is critical to catching small leaks before they damage inventory or equipment.

What voids a commercial roof warranty?

Common warranty voiders include unauthorized modifications (like adding new HVAC units without proper flashing), lack of documented routine maintenance, ponding water issues left unaddressed, and unauthorized foot traffic damage.

Can rooftop equipment damage a membrane?

Yes. Unprotected foot traffic from HVAC technicians, dropped tools, and improper equipment curbs are leading causes of membrane punctures. We install protective walkway pads around all mechanical units.

How long does TPO last?

With proper installation and bi-annual maintenance, a commercial TPO roof can last 20 to 30 years in Central Alabama.

Can roof coatings extend service life?

Yes. If your current roof is structurally sound and the insulation is dry, a silicone or acrylic roof coating can add 10 to 15 years of waterproof life at a fraction of the cost of a full replacement.

Is infrared scanning worth it?

Absolutely. Infrared (thermal) scanning detects hidden moisture trapped in the insulation underneath the membrane. This allows us to perform targeted repairs instead of tearing off the entire roof.

How do I know if insulation is wet?

Signs include a spongy feel when walking on the roof, localized membrane blistering, interior ceiling stains, and musty odors inside the building. An infrared scan provides definitive proof.

What's the difference between TPO and PVC?

Both are white, heat-welded single-ply membranes. TPO is generally more cost-effective and performs well in most situations. PVC is highly resistant to chemicals and grease, making it the required choice for restaurants and manufacturing facilities.

Should I repair or replace an aging roof?

If more than 25% of the roof requires repair or if the insulation is widely saturated, replacement is usually the most cost-effective long-term option. If the damage is localized and the membrane is still pliable, repair is recommended.

What is a roof overlay?

An overlay involves installing a new membrane directly over the old one. Building codes typically allow a maximum of two layers. It saves money on tear-off but is only an option if the existing insulation is dry.

Does commercial insurance cover roof replacement?

If the roof was damaged by a covered peril (like a severe hail or wind storm), insurance should cover the replacement. However, commercial policies often have complex deductibles and depreciation schedules.

What is an ACV vs. RCV commercial policy?

Actual Cash Value (ACV) pays only the depreciated value of your old roof. Replacement Cost Value (RCV) pays the full cost to install a brand new roof at today's prices.

How do you handle roof drainage?

We ensure proper slope using tapered insulation, clear all scuppers and internal drains, and install crickets around large HVAC units to divert water and prevent ponding.

Quick Answer: Best Commercial Material?

"For flat or low-slope commercial roofs in Alabama, TPO (Thermoplastic Polyolefin) is the industry standard. Its white, reflective surface significantly reduces cooling costs during our 100°F summers, and its heat-welded seams provide superior leak protection against torrential afternoon thunderstorms."
