Commercial & residential low-slope roofs

Start with the roof condition and the building

Tell us about leaks, the existing roof and how the property is used. We look at affected areas, drainage, edges, penetrations and access before recommending a repair or replacement scope.

Assess the roof before choosing a system

TPO and modified bitumen are options to discuss alongside the condition of the existing roof and the building’s needs. The proposed materials, preparation and installation details should be clear before work is scheduled.

Details that deserve attention

Drains, roof edges, equipment curbs, flashing and transitions all belong in the scope conversation. Tell us where water appears inside, whether the problem returns after repairs and which parts of the building need to stay accessible.

Repairs are welcome

A leak does not automatically call for a new roof. We explain whether a focused repair can address the cause or why a larger scope makes sense. Homeowners with low-slope additions can reach us through the same request form.

Plan around the property

Send the property’s city, a description of the issue and useful roof photos. We discuss access and scheduling alongside the roofing work. Our service area includes San Antonio, Austin and surrounding communities.

Frequently asked questions

Commercial and low-slope questions

What is TPO roofing?

TPO is a single-ply roofing membrane used on low-slope roofs. Its seams are heat-welded. The membrane, attachment, insulation, drainage and flashing details need to work together as a roof system.

What is modified bitumen roofing?

Modified bitumen uses reinforced, polymer-modified asphalt sheets in a layered roof assembly. The selected products and installation method depend on the roof and the proposed scope.

Can you repair a commercial or low-slope roof?

Yes. Tell us where the leak appears, when it happens and what repairs have already been tried. We inspect the affected area and surrounding roof before recommending a focused repair or a larger scope.

Do you work on residential flat roofs too?

Yes. Homeowners with low-slope roofs, additions and porch roof concerns are welcome to contact us. We assess the roof and discuss suitable options for that part of the home.

What information helps you prepare an estimate?

Send the property's city, the issue you are seeing, any available roof photographs and your timing. For occupied buildings, tell us about access, business hours and areas that need to remain available during the work.
