Nail roofing felt

The classic method of fixing roofing felt is nailing. While nailing in oblique roofs is already sufficient to protect against running water such as rain or snow, it is rarely used for flat roofs. Special roofing nails with wide heads prevent the tearing of nail holes. Often, prior fixing with a staple gun is a helpful advance to ensure proper nailing of the roofing felt. When driving the nails also fingertip feeling is needed.

Proper distances and depth are crucial

When unrolling the first web, a first fixation with a tacker or with two roofing nails should be made at the beginning of the run to avoid slippage during the rolling and laying process.

After the first track has been completely unrolled in its length, two nail levels must be applied. At the bottom edge of the track, the distance between the individual nails should not be more than forty centimeters. The edge must be kept at least five centimeters apart.

The second nail plane should be placed approximately half the width of the track parallel to the nails on the lower edge.

When nailing the roofing felt, pay attention to the force of the blows. The wide heads of the roofing nails must be placed on the surface and must not be pressed or injured. For this we recommend a lighter hammer.

Subsequent sealing of the nail heads

After laying the next web, first nail the overlapping webs lengthwise. Due to the double thickness of the roofing felt, the nail path is shorter and the risk of injury to the surface in case of too strong blows even higher.

After completion seal all nail heads with liquid bitumen, mastic or asphalt from the spray tube.
