Replace roof felt from inside.

If the roof felt has failed then that alone is likely to cause a leak if the amount of water on the roof is large and water gets in between the tiles. The air needs to come from outside the roof space. The holes in the felt won t lead directly outside only to the gap between the felt and the tiles which won t cause air to flow into the building. The whole roof felt doesn t always age evenly.

Where wind driven rain is working under the roof and causing leaks then the felt will need to be replaced. When the heat from your home melts snow or ice on your roof the water can then seep into. To replace a small section of roofing felt involves stripping the tiles from the roof and replacing felt between two joists. It provides backup protection in the event of ice or water damage in northern climates ice or snow dams are another common cause of residential water damage.

Roofing felt helps ensure the water drains off the roof and doesn t leak into your home. Of all major home repairs installing new roofing is arguably as important as it gets. The roof felt allows water to run down the roof into the guttering if it gets beneath the roof tiles which it often can especially with deep snow.
