Commercial Roofing Services for Pittsburgh Businesses

Commercial roofing in Pittsburgh has to protect more than a building. It protects inventory, equipment, tenants and the hours your business is open. Straight A Exterior Renovations provides commercial flat roofing, TPO, EPDM rubber roofing, roof coatings, roll roofing and commercial roof inspections for business owners and property managers across the Pittsburgh area.
Our commercial work covers new roof systems, replacements, repairs and restoration coatings on flat and low-slope roofs. That includes retail buildings, offices, small industrial and warehouse buildings, mixed-use properties and multi-unit buildings. We inspect the roof, explain its condition in plain terms, and recommend the system that fits the building and your plans for it.
Flat roofs face a particular set of problems here. Snow sits on them for weeks, freeze-thaw cycles work at seams and flashing, and summer storms test drainage all at once. Ponding water, blocked drains and failing seams are the issues we see most often. Left alone, a small membrane split can soak insulation across a large area before a leak ever shows inside.
Professional commercial roofing means planning around your operations, keeping the site safe and organized, and documenting the work so you have a clear record for owners, tenants or insurers. Our team brings over 30 years of combined roofing experience, and a dedicated project manager stays with your project from inspection to completion.

What's included
Commercial Roofing Systems We Install and Repair
Different buildings need different systems. These are the commercial services we provide.

Commercial flat roofing
We install and repair flat roof systems on commercial buildings of many kinds. The focus is on drainage, seams and edge details, which are where flat roofs usually fail.
TPO roofing
TPO is a single-ply membrane with heat-welded seams and a light-colored surface that reflects sunlight. It is a common choice for low-slope commercial roofs that need a durable, watertight surface.
EPDM rubber roofing
EPDM is a rubber membrane with a long track record on flat roofs. It stays flexible in cold weather, which suits Pittsburgh winters, and it can be repaired cleanly when damaged.
Roof coatings
On a roof that is worn but still sound, a coating can seal small cracks and extend its useful life. We inspect first and tell you honestly whether a coating makes sense or whether the roof is past that point.
Industrial roofing
Industrial and warehouse buildings often have large roof areas, rooftop equipment and many penetrations. We plan the work in sections and detail each penetration so the roof stays watertight.
Roll roofing
Roll roofing is a practical option for some low-slope outbuildings, sheds and secondary structures. We will tell you where it fits and where a membrane system is the better choice.
Low-slope roofing
Many commercial and mixed-use buildings have roofs that are not quite flat. We select and install systems rated for low slopes so water drains rather than sits.
Commercial roof inspections
A commercial roof inspection records the condition of the membrane, seams, flashing, drains and rooftop equipment curbs. You get photos and a plain-language summary to plan repairs or budget for replacement.
How it works
How Our Commercial Roofing Process Works
Here is how we take a commercial roof from first inspection to a finished, documented job.
- Step 1
Roof inspection and assessment
We inspect the roof surface, seams, drains, flashing and penetrations, and document what we find with photos.
- Step 2
System recommendation and proposal
We explain repair, coating and replacement options and send a written proposal with scope, materials and warranty details for that system.
- Step 3
Scheduling around operations
Your project manager plans timing, staging and access with you so the work fits around business hours, tenants and deliveries.
- Step 4
Installation
The crew installs the approved system in planned sections, keeping the building weather-tight at the end of each work day.
- Step 5
Final inspection and walkthrough
We inspect the finished roof, clear all debris, and walk the roof or review photos with you so you have a complete record.
FAQ
Commercial Roofing questions from Pittsburgh homeowners
What types of commercial roofs do you work on?
We work on flat and low-slope commercial roofs, including TPO, EPDM rubber, roll roofing and coated roof systems. We serve retail, office, industrial, warehouse, mixed-use and multi-unit buildings in the Pittsburgh area.
Should I repair, coat or replace my commercial roof?
It depends on the condition of the membrane and the insulation underneath. If the roof is sound with surface wear, a repair or coating may be enough. If water has soaked large areas, replacement is usually the better value. Our inspection gives you the facts to decide.
Can you work without shutting down my business?
In most cases, yes. We plan staging, access and noisy work with you ahead of time so customers, tenants and staff can keep using the building.
What warranty comes with a commercial roof?
Warranty coverage depends on the roofing system we install. The specific terms are spelled out in your written proposal so you know exactly what is covered before you approve the work.
TPO or EPDM: which is better for my building?
Both are proven flat roof membranes. TPO has a reflective surface and heat-welded seams, while EPDM is a flexible rubber that handles cold weather well. We recommend one based on your roof, its use and your plans for the building.
Do you handle emergency leaks on commercial roofs?
Yes. We offer 24/7 emergency roofing to stop active leaks and protect the building, followed by a permanent repair.
Can you help with an insurance claim for storm damage?
Yes. After a storm we document damage to the membrane, flashing and rooftop details with photos and notes, help you report it, and work with your carrier's adjuster through the claim. Commercial policies vary, so check your coverage and reporting requirements.
Do you provide commercial roof inspections for property managers?
Yes. We inspect the roof and give you photos and a plain-language summary of its condition, which helps with planning repairs, budgeting and reporting to owners.
