Flat Roofing in Longview, Washington

Flat Roofing in Longview means roofing built for the Washington climate - the heat, the humidity, and the storms. The Washington humidity and the severe storm remnants test every roof, and the tree debris covers the surface.

Signs Your Longview Roof Needs Flat Roofing

• Ponding water that lasts more than 48 hours - the drainage is not enough
• Blisters or bubbles under the membrane - the trapped moisture expands in the heat
• Cracked or brittle surface - the UV has aged the material
• Leaks at the seams or the flashings - the thermal cycling has opened the gaps
• Granules or gravel in the downspouts - the surface is wearing away

Why Longview Roofs Need Flat Roofing

The heat is the main factor. The Washington sun heats the flat roof surface and the white TPO membrane reflects the heat. The dark materials would absorb the heat and shorten the roof life.

The storm rain is the second factor. The flat roof needs the right slope to the drains.

How We Do Flat Roofing in Longview

1. Inspect the deck and the slope - check the structure and the drainage
2. Install the insulation - the polyiso insulation for the thermal barrier
3. Lay the membrane - the TPO or the modified bitumen
4. Weld the seams - the heat-welded seams for the TPO, the torch-down for the modified bitumen
5. Flash the penetrations - the drains, the vents, and the HVAC curbs

Preventing Problems in Longview

• Check the drains after every storm - the debris blocks the flow
• Inspect the seams each spring - the thermal cycling stresses the welds
• Apply a reflective coating when the membrane ages - the UV protection buys more years
• Keep the HVAC units off the damaged areas - the foot traffic wears the surface

The flat roof in Longview is a cooling tool. The white TPO membrane reflects the Washington sun and the building stays cooler. The right slope and the clear drains are the key to the long life.
