Commercial Roofing

Who Handles Commercial Roofing on the Grand Strand?

Waccamaw Roofing, LLC installs, repairs, and maintains commercial roofs for business owners and property managers across Myrtle Beach and the Grand Strand. We work on retail stores, offices, warehouses, and multi-unit buildings, and every project starts with a free inspection and a written estimate.

A commercial building has a lot riding on its roof. Stock, equipment, tenants, and daily sales all sit under it. When it leaks, the cost is more than a repair bill. That is why the right system, a careful install, and steady upkeep matter so much.

This page explains how commercial systems work, the main types, how to decide between repair and replacement, and what to expect when you call us.

What Does Coastal Weather Do to a Commercial Roof?

Buildings near the ocean face a mix of stress that inland buildings do not. Here is how each force shows up on a low slope roof.

Wind. Strong gusts try to lift the edges and corners of a membrane. If the edge metal or fasteners are weak, the wind can get under the sheet and peel it back.

Rain. Heavy summer storms dump a lot of water fast. If a drain is clogged or the deck has a low spot, water ponds and sits. Standing water finds every weak seam.

Salt. Salt air speeds up rust on metal edges, fasteners, and rooftop units. Rust around a flashing detail is a common starting point for leaks.

Sun and heat. Long, hot summers break down some surfaces over time. They also drive up cooling costs when the roof absorbs heat instead of reflecting it.

A good system, installed with care, handles all of this. The details at the edges, drains, and openings make the biggest difference.

How Is a Commercial Roof Different From a Home Roof?

Most homes have steep slopes covered in shingles. Most commercial buildings have flat or low slope roofs covered by a membrane or a built-up system. That one change affects almost everything else.

On a steep slope, water runs off fast. On a low slope, it moves slowly toward drains, scuppers, and gutters. Seams, flashing, and every opening carry more of the load. A small gap that would shed water on a house can hold a puddle on a flat deck.

Commercial roofs also carry more. Heating and cooling units, vents, pipes, and walkways all sit on top. Each one needs proper flashing and support. Crews and service techs walk the surface, so it has to handle foot traffic too.

Finally, a commercial system has to manage heat. A light, reflective surface can keep the space below cooler in our long summers. Insulation under the membrane plays a big part as well.

What Are the Warning Signs of a Failing Commercial Roof?

Many commercial leaks start well before anyone sees a drip. Watch for these signs, inside and on top.

Stains on ceiling tiles. A brown ring or a sagging tile is often the first clue.
Water that stays after rain. Puddles that last more than a day or two point to drainage or deck problems.
Blisters and bubbles. Raised spots in the surface can mean trapped air or moisture below.
Open or lifted seams. Gaps where two sheets meet let water run under the membrane.
Loose edge metal. Metal that rattles or lifts in the wind gives the next storm a place to start.
Soft spots underfoot. A spongy feel often means wet insulation below.
Higher cooling bills. Wet insulation stops working, and the building gets harder to keep cool.

If you notice any of these, call us for a free inspection. Finding the cause early keeps a small repair from turning into a large one, and it protects what sits under the roof.

Which Commercial Roofing Systems Do We Install?

We work with the main commercial systems used on the coast. Each one fits a different kind of building.

TPO. A white, single ply membrane with heat welded seams. It reflects sunlight, which helps keep the building cool.
PVC. Another single ply membrane with welded seams. It holds up well where grease or chemicals are present, such as near restaurant vents.
EPDM. A flexible rubber membrane with a long track record. It handles sun and swings in temperature well.
Modified bitumen. Layers of asphalt based sheets. It is tough and resists punctures, which helps on roofs with a lot of foot traffic.
Built-up systems. Several layers of asphalt and felt, often topped with gravel. They have served larger buildings for many years.
Standing seam metal. Metal panels with raised seams. They shed water well and stand up to wind when fastened right.

Salt air, strong sun, high winds, and humidity all shape the choice here. Strong seams, secure attachment, and a reflective surface tend to pay off over time. We look at the slope, the use of the building, the drains, and the deck, then explain the options in plain terms.

Should You Repair or Replace a Commercial Roof?

Start with the facts, not a guess. We look at four things: the age of the system, how often and where it leaks, the condition of the surface, and whether the insulation below is wet.

Repair usually makes sense when:

The leaks are in one area, such as around a unit or a drain.
The seams are failing in spots, but the rest of the membrane is sound.
The insulation below is dry.

Replacement is often the better choice when:

Leaks keep coming back in new places.
Large areas of insulation are wet. Wet insulation stops working and adds weight.
The surface is cracked, shrinking, or worn across most of the roof.

In some cases, part of the building needs new work while the rest only needs repairs. We explain each option and put it in a written estimate, so you can plan the budget with clear numbers.

What Upkeep Does a Commercial Roof Need?

A little care each year goes a long way. We suggest a check in the spring and again in the fall, plus one after any major storm.

Clear leaves, trash, and debris from drains, scuppers, and gutters.
Look for ponding water a day or two after rain.
Check the seams, the edges, and the flashing around every unit and pipe.
Look for rust on metal edges and fasteners.
Keep a log of each repair, with dates and photos.

Ask your tenants and staff to report any drips or stains right away. The sooner a leak is found, the less it costs. For guidance on good roofing practice, the National Roofing Contractors Association publishes resources for building owners and contractors.

What Should You Expect When You Call Us?

First, we set a time to walk your building. We check the surface, the edges, the drains, and every unit on top. We look inside for stains and signs of leaks. Then we talk with you about what we found.

Next, you get a written estimate. It spells out the work, the materials, and how the job will run. If the building stays open during the work, we plan around your hours and your tenants as best we can.

During the job, we keep the site clean and safe. When we finish, we walk the roof with you so you can see the work. After that, we are a phone call away for upkeep and repairs.

Commercial Roofing FAQs

What types of commercial roofing systems are there?

The main types are single ply membranes such as TPO, PVC, and EPDM, modified bitumen, built-up systems, and standing seam metal. The right one depends on the slope, the use of the building, and the budget.

What is the difference between TPO, PVC, and EPDM?

TPO is a white, reflective membrane with welded seams. PVC also has welded seams and resists grease and chemicals. EPDM is a flexible rubber membrane with a long track record. Each suits a different kind of building.

How long does a commercial roof last?

It depends on the system, the quality of the install, the weather it faces, and how well it is kept up. Regular checks and quick repairs help any system last longer.

When should a commercial roof be repaired instead of replaced?

Repair fits when the damage is in one area and the insulation is dry. Replacement is often better when leaks keep coming back, the insulation is wet, or the surface is worn across most of the roof.

What upkeep does a commercial roof need?

Keep drains clear, check the seams and flashing, watch for ponding water, and fix small problems fast. A check in spring and fall, plus one after big storms, is a good plan.

How is commercial roofing different from residential roofing?

Commercial roofs are usually larger and flat or low slope, with membranes and rooftop units. Home roofs are usually steep and covered in shingles. See our residential roofing page for homes.

What affects the cost of a commercial roofing project?

Size, the system you choose, the condition of the deck, insulation needs, and how many units and openings are on top. We give you a written estimate after a free inspection.

Do you work on commercial buildings outside Myrtle Beach?

Yes. We serve businesses across the Grand Strand, including Conway, North Myrtle Beach, Murrells Inlet, and Pawleys Island.
