Roofing Felt

If asked whether they think that they could lay a roof or not, most DIY enthusiasts would jump at the chance but those individuals with very little experience would probably balk at the idea. The thing is though that lying roof felt is nowhere near as difficult as you think it is. Whether you would be laying roofing felt on a storage shed or a full sized house, the process is the same and relatively easy if a little time consuming and can be found outlined below for you.

Before you even consider laying roofing felt on your home or storage shed, you do need to make sure that you have all of the right materials with you. For example, you need to make sure that you have the right roofing felt in advance. The lightweight shed roofing is not suitable for flat roofs because it is nowhere near heavy enough and will succumb to the elements over time, but it would be suitable for an outhouse roof that is slanted and slightly sheltered.

Accurate assessment is a must before you start for this reason. You will also need to have measured the roof you wish to lay roofing felt on and cleaned it well before you start. The former has to be done because if you do not have enough then you could be leaving yourself open to structural damage. The latter has to be done to make sure that you can lay it properly. When you have taken those three steps, it is time to move on to laying the felt.

Laying Roofing Felt

1. Lay The Underlay – The underlay is the first layer of roofing felt you need to lay and it should not be bonded to the roof with adhesive as some sources say. It needs to be able to move if the roof expands and contracts. Spread it over the roof and then secure it at the edges with nails before cutting any excess felt away afterwards.

2. Lay The Second Bonded Layer – Repeat the process for the first step but this time use adhesive to bond it to the underlay roofing felt. You should not attach the second layer with nails at all. When cutting the felt, leave approximately six inches hanging by the guttering sides. Leave the adhesive to dry for at least two or three hours before moving on to step four. In the meantime, go to step three.

3. Install Gutter Drips – Your guttering should already be in place. If it is not then install it before doing the gutter drips. Take the six inch overhang of felt and use nails to direct it vertically downwards. Attach it to the wall just below using nails again to ensure that all run off goes into the gutter.

4. Lay The Top Sheet – This is the same process for step two, with the exception of leaving the overhang slightly. You can either use adhesive or nails for this particular part. Providing that the roofing felt is perfectly fitted it will not matter which.

5. Seal The Roof – You will need to apply sealant to the roofing felt to make sure that it is completely protected from the elements but always be sure to follow the instructions on the can for this particular step because sealants are different.

6. Check Your Roof – Finally, go over your roofing felt, tidy up any loose edges and be sure to make sure that sealant has been applies evenly. If in doubt, apply another coat just to be on the safe side.
It really is that simple. You will need a day to complete this task and must make sure it is a warm and dry day before you do so. After that though, you should have a functional roof courtesy of a little time and roofing felt.
