Commercial Roof Repair in Murphy

Murphy's commercial buildings are mostly offices, retail centers, medical practices and schools, many built in the last twenty years or so. Their roofs are often single-ply or modified bitumen, with rooftop units scattered across them. When a leak appears near one of those units, it is easy to assume the roof failed. Sometimes it did. Sometimes the water is coming from the unit itself. A careful look saves money either way.

We also work in Wylie and Parker. On every call, we find the real source first and then recommend the right fix.

Hail and high wind are part of life in Collin County, so we also check for storm damage while we are on the roof.

Trace the leak before blaming the roof

Water near rooftop equipment can come from several places. The curb flashing may have pulled away. A pipe boot may have split. Or the unit's condensate line may be clogged and overflowing, or its drain pan may be cracked. From inside the building, all of these look the same.

A commercial roof inspection checks the roof details and the equipment around them. We look at curb flashing, counterflashing, pipe boots, the membrane around the unit and the condensate drain. If the water is coming from the unit, we tell you so your HVAC contractor can fix it.

We also check for water traveling along the deck. A leak near a unit might actually start at a seam several feet uphill, especially on a roof with poor drainage.

When we find the source, we photograph it and tie it to the interior location your team reported. If we are not certain, we say so and recommend a water test or a follow-up visit after the next rain.

Match the fix to the failure

Seams and flashing fail in different ways and need different repairs. A seam failure on an EPDM roof often means the seam tape or adhesive has let go along a stretch of the seam. The fix is to clean and prime the area and install a new cover strip over the full length of the weak seam, not just the spot that is leaking.

Flashing failures usually happen where the membrane turns up a wall or curb. The flashing may have shrunk, pulled loose or cracked at the corners. The fix is new flashing, properly adhered and terminated, with corners reinforced.

We match all repair materials to the existing roof. EPDM gets EPDM primer, tape and flashing. If a past contractor used an incompatible patch, we remove it first.

We also explain why the repair is the size it is, so you understand why a small leak can need a larger repair.

Decide what can stay

Sometimes a repair is the right call. Sometimes the roof has reached the point where a recover or replacement makes more sense. The answer depends on what is under the membrane.

We check the insulation with test cuts or cores. If it is mostly dry, the roof may be a candidate for repairs now and a recover or coating later. If large areas are wet, repairs will only buy a short time, and replacement may be the better investment.

For roof capital planning, we lay out each option with its scope, price range and assumptions. A recover, for example, assumes the existing insulation is dry enough to stay and that the roof does not already have too many layers. We tell you what we have confirmed and what still needs checking.

We do not push replacement when a repair will do the job. We also do not keep patching a roof that needs more.

Age alone is not the deciding factor. A twenty-year-old roof with dry insulation and sound seams may have plenty of life left with good maintenance, while a younger roof with poor drainage may already be failing.

Work around an occupied building

Most Murphy commercial buildings stay open while we work. On an office building, we ask about business hours, parking, tenant notification and any noise limits. Tear-off and fastening can be loud, so we schedule that work when it will disturb the fewest people.

We also check where the crew will access the roof, where materials will be staged and where debris goes. If the only access point is through a tenant space, we coordinate with that tenant ahead of time.

Odors are another concern. Some primers and adhesives have strong smells that can be pulled into the building through rooftop air intakes. We note intake locations and work with your HVAC contractor to shut them down or protect them while we work.

Weather plays a role too. If rain is forecast, we do not open the roof. We would rather reschedule than leave the building exposed.

Explain the price and the result

Our price is based on what we found. It lists each repair, its location and what is included. If the scope changes because we find wet insulation or damaged deck, we stop, show you photos and give you a revised price before continuing.

When the work is done, you get a report with the interior leak location, the roof source, any hidden damage, the finished repair and photos of each stage. If the leak was traced to HVAC equipment, the report says so clearly.

We also list nearby problem areas we did not repair, such as aging seams or a drain that holds water, so they can go on your maintenance list.

If we recommended considering a recover or replacement, the report includes our reasons and what still needs to be confirmed. That gives you and your finance team something solid to plan around.

Commercial Roofing Questions

Is water near rooftop equipment always a roof leak?

No. It can be a clogged condensate line, a cracked drain pan or failed curb flashing. We check both the roof and the equipment before pricing a repair.

How are seam repairs different from flashing repairs?

A seam repair covers the full weak length of the seam with new tape or cover strip. A flashing repair replaces the membrane where it turns up a wall or curb, with reinforced corners.

When should a recover or replacement be considered instead of repair?

When test cuts show large areas of wet insulation, or when the roof has too many failures to keep patching. We price each option so you can compare.

What can change a repair price?

Wet insulation, damaged deck or rotted wood found when the roof is opened. We photograph it and explain the added cost before continuing.

What should the final report show?

The interior leak location, the roof source, any hidden damage, the finished repair with photos and other areas worth watching.
