Ponding water
Water that stays on the roof for a day or more after rain can shorten the life of the membrane.
TPO and EPDM flat roofing
Low-slope roofs drain differently, so they need different materials and detailing. We install and repair TPO and EPDM membranes on additions, porches, dormers and commercial buildings.
Overview
Flat roofing in Fredericksburg and Northern Virginia
Flat and low-slope roofs are common on home additions, porch roofs, and commercial, retail and industrial buildings. Because water drains slowly, seams, edges and penetrations have to be detailed carefully.
We work with the two membrane systems most used on low-slope roofs: TPO, the light-colored reflective membrane, and EPDM, the black rubber membrane with a long track record.
Warning signs
Signs a flat roof needs attention
Open or lifting seams
Seams that separate let water under the membrane.
Blisters, cracks or tears
Surface damage that exposes the layers below the membrane.
Leaks around penetrations
Vents, pipes, skylights and drains are the most common leak points.
Options
Flat roofing systems
Both are single-ply membranes. The right choice depends on your building and budget.
How it works
What to expect, start to finish
Free inspection
We look at the roof and the areas around it, and talk through what we find before anything is priced.
Estimate
We measure, look at drainage and penetrations, and recommend a system.
Installation or repair
We prepare the substrate, install the membrane and seal edges, seams and penetrations.
Maintenance advice
We tell you what to check and how often, so small issues get caught early.
Honest considerations
Things worth weighing
- Drainage matters more than material. If water cannot leave the roof, even a new membrane will have a shorter life.
- Dark membranes absorb more heat than light ones. TPO helps reduce cooling loads in summer.
- Flat roofs benefit from periodic inspection, especially after storms.
Questions
Flat roofing: common questions
What is TPO roofing?
TPO is a single-ply reflective membrane, usually white, that resists UV, chemicals and punctures. Its seams are heat-welded, and it is popular on commercial and industrial roofs.
What is EPDM roofing?
EPDM is a black synthetic rubber membrane known for its flexibility in extreme temperatures and a long track record. It can last 20 to 30 years with maintenance.
Can you fix a leak on a flat roof?
Often yes. Many flat roof leaks come from a failed seam, flashing or penetration. We find the source before recommending a repair or replacement.
Do you do flat roofs on homes or only commercial buildings?
Both. Flat roofs are common commercially, and we also do them on home additions, porches and dormers.
