No matter what your plan is for the building, one rule holds: you will reap what you cheap. Cut a corner today and you do not hand the bill to the next owner. You pay it, with interest, later.

‍

Your building wants to live a long time. Nobody feeds their own body junk on purpose and expects to run a marathon at 80. Yet when it comes to the one part of the building they cannot see, the roof, owners suddenly go hunting for the cheapest garbage bag they can staple up there. Let us fix that. Welcome to McRoofing. Four items on the menu, and you get to choose.

‍

Quick Answers

‍

Q.  What are my options besides a full roof replacement?

A.  Four of them. You can patch the trouble spots, coat the whole roof with a seamless liquid system, overlay a fresh layer over the existing roof, or tear everything off and start at the deck. Most owners only ever get a price on the last and most expensive one. The other three are often the smarter buy.

‍

Q.  Is it legal to put a new roof over my old roof?

A.  Yes, up to a point. The International Building Code allows a maximum of two roof layers. If you already have one roof, an overlay is on the table. If you already have two, code requires a full tear-off before anything new goes on. A quick core sample tells us which camp you are in.

‍

Q.  How much does a commercial roof tear-off cost?

A.  Plan on roughly $1 per square foot for the tear-off alone, and that is before dumpsters, disposal, and swapping out any deck boards that have gone soft. Tear-off is the most expensive path, which is exactly why we try to avoid it when a patch, coat, or overlay will do the job.

‍

Q.  What is a roof overlay, and will it really save me money?

A.  An overlay adds a fresh layer, often new insulation, right over your existing roof, then a new surface on top. Beyond the leak protection, that added insulation can trim your monthly energy bill. Sometimes the roof quietly pays for a piece of itself.

‍

Q.  Why do you steer owners away from rubber roofs?

A.  Because rubber looks cheap up front and gets expensive on the back end. It can hold up in the open field, but the seams, edges, and perimeters are where it lets go under heat, ice, and years of weather. When you add up the long term cost of ownership, the bargain disappears.

‍

Q.  I am planning to sell soon, so why fix the roof at all?

A.  Because the bill does not transfer as cleanly as you hope. Selling a commercial building takes time, and selling the business inside it is even harder. On the major platforms, the median close rate for a bundled business and real estate deal is around 6.5%. Buyers send inspectors, and a neglected roof shows up in the moisture, the rot, and the price they offer.

‍

Q.  How do I compare all these options fairly?

A.  You put real numbers next to each one. We measure, photograph, test for moisture, and hand you a patch price, a coating price, an overlay price, and a tear-off price, side by side. Then you decide with your eyes open instead of guessing.

The Short Version

‍

If your commercial roof is aging, you do not have one choice, you have four: patch it, coat it with a seamless liquid system, overlay a fresh layer, or tear it off and start over. Most owners only ever price the tear-off, get sticker shock, and stall. That is the expensive mistake. The building code lets you carry up to two roof layers, an overlay can even trim your energy bill, and rubber is usually the trap that costs more over time than the honest option would have. Whatever your plan, you will reap what you cheap, so the wise move is to get all four options priced side by side and choose with real numbers in hand.

‍

1   Welcome to McRoofing

‍

Picture a drive-through menu, but for your roof. Four items, four prices, and you get to choose. Most owners never see the full menu. Somebody quoted them the most expensive item once, they choked on the number, and they have been patching with buckets of tar and hope ever since. Let us put the whole menu in front of you.

‍

2   The Four Options, One by One

‍

1.  Patch. The smallest, cheapest move. We fix the specific trouble spots. Good for buying a little time, not for solving an aging roof.

‍

2.  Liquid coat. A seamless coating from edge to edge that erases the seams and gives you a solid, reflective surface, good for 20 years and up. This is the sweet spot for a roof that still has honest life left in it.

‍

3.  Overlay. We make the roof thicker. Add a fresh layer of insulation over the existing roof, then a new surface on top. Your roof was 2 inches thick, now it is 4 or 5. The added insulation can lower your energy bill, so part of it pays for itself. Legal as long as you do not already have two roofs up there.

‍

4.  Tear-off. The nuclear option. Rip everything down to the deck, haul it to the landfill, replace the soft boards, and build new. Around $1 per square foot just to tear off, before disposal. Sometimes a building truly needs it. Often it does not, and we work hard to keep you off this line of the menu.

‍

3   The Two-Roof Rule

‍

Here is a fact worth knowing before anyone sells you a tear-off you may not need. The International Building Code allows a maximum of two roof layers on a low slope roof. If you have one roof, an overlay is legal and usually smart. If you already have two, code requires a full tear-off before a new roof goes on. A simple core sample settles it in minutes. Do not let anyone skip this step.

‍

4   The Cheap Trap: Why Rubber Fails

‍

Rubber sounds great on the surface. It is cheap. But cheap up front is not the same as cheap to own. Rubber can be strong in the middle of the field, but a roof does not fail in the middle. It fails at the seams, the edges, and the perimeters, and that is exactly where rubber gives out. Heat pushes past 160 degrees up there. Ice, rain, grease, and years of sun go to work on the adhesive until the seams let go. Now you own a bargain that leaks. The cheapies to avoid all share that same story: strong-sounding, weak-lasting.

‍

5   The Car in the Parking Lot

‍

Let me sell you a $1,500 car. What is your first question? Probably, does it even run. Now let me sell you a $15,000 vehicle. Your questions change. How many owners? How many miles? Was it maintained? Here is the one question you cannot ask out loud, because nobody can answer it: how many miles does it have left? That is the real thing you are buying, the future miles you cannot see. Your building is the same. Every roof has future miles left in it, and the cheap choice quietly burns through them faster than you think.

‍

6   You Will Reap What You Cheap

‍

Owners love to believe the roof is the next guy's problem. It rarely works out that way. Selling a commercial building takes time, and selling the business that lives inside it is harder still. On the big listing platforms that bundle the company with its real estate, the median close rate sits around 6.5%. Read that again. Fewer than 1 in 15 make it from listed to sold.

‍

The shell, the building, is the easy part to move. The goodwill, the operating company, the owner who is the business, that is the anchor. So the plan to cut a corner now and hand the bill to a buyer usually ends with you still holding both the building and the bill. Inspectors find the rot, the moisture, the sag. You pay, now or at closing. Better to pay for wisdom than to pay for neglect.

‍

7   The Smart Move: Price All Four

‍

You would not choose a car, a floor, or a home by asking only what is the cheapest option that will not immediately fall apart. Do not choose your roof that way either. You owe it to yourself, your team, and the future owner to at least know the numbers. Let us put a real price next to patch, next to liquid coat, next to overlay, and next to tear-off. Four numbers, side by side. Then you make a wise choice with your eyes open.

The Bottomline

‍

Your roof has four honest options, not one. Patch, coat, overlay, tear-off. The building code, your energy bill, and the long term cost of ownership all reward the owner who reads the whole menu instead of flinching at the priciest item. You will reap what you cheap. So get all four priced, and choose like the wise owner you are.
