Going to reshingle my roof. What should I do about the tar paper and edging and ice shield?

Question

Should I leave these in place or is it normal practice to replace these items when reshingling?

Answer 1

Always replace the tar paper,there could be wood damage underneith also put drip edge on the sides or the sides will rot,and I helped my ex-hubby in roofing.So I do Know!

Answer 2

People do use d-edge on all sides of the roof. The ice and water shield which is the 4 foot sticky stuff [code]The felt has to be 30 lb I think.Then the d-edge goes on,the shingles should hang over the drip edge about 1/4". The felt goes under the drip edge.Good Luck

Answer 3

This is an issue I have wondered about; not the replacing asphalt felt - that you should do and it comes off easily, but what to do about the self-adhesive ice shield that is now required in many areas along the lower edge of the roof to prevent water damage from flooding behind ice dams.


This material sticks down tightly and I don't see how it can ever be removed. You will probably just have to put a new layer down over it. local codes may require this material to extend up three feet from the lower edge of a roof that is over an area heated in winter.

I think trying to remove this stuff would be an exercise in futility, as it is so sticky and having been on the roof for years will have stuck down permanently. it's not worth the effort to try to remove it, since about the only way to get it up would be to rip up the roof deck itself, and you'd only need to do that if parts of it are damaged or rotted.

Answer 4

Strip the roofing materials down to the bare boards.

Check roofing boards for rot, cracks, weak areas, raised nails

Fix/replace where necessary.

Check local building requirements for rain and ice shield.

Felt (tar) paper should be layed down an all parts to the roof where no rain and ice shield is used.

The underlays (felt Paper, rain and ice shield) should be started from the lower edge (facia) to the peak with about 6 " overlap.

Low slope roofs, areas where snow builds up and does not melt quickly, valleys, roof meets verticle wall and chimneys, etc should be completely covered with rain and ice shield.

Most shingle manufacturers do not guarantee their shingles if felt paper is not put down under the shingles.

If you are not doing this yourself heres is some extra information.

==============================================

Selecting contractors:

1/ Look up local contractors first. work out form the closest
to your location. If some you trust has had work done
similar to yours, ask them about the contractor they
used. If they were completely satisfied with their
contractor(s), ask for their telephone number.

2/ Select at least 5 your are interested

3/ Do a google/yahoo search on each of the contractors
you are interested in; look for praises (check who is
writing the praises to see if they have any connection to
the contractor work in groups> google/yahoo search the people giving
the praise or references)

4/ When you are satisfied with at least 3 contractors per job,
have the give you written estimates with details of work
to be done, terms, guarantee(s), cost of extras (how
much do they charge if they find something not covered
by the contract), paymant schedules if necessary and
whatever else you can think of to protect yourself.

5/ If the contractor tries to pressure you into signing the
contract immediately with a high deposit (more than
15%) reject that contractor. Be careful, high pressure
can be someone who sounds very convincing, but has
many reasons why you should sign on the dotted line
NOW.

6/ It is always good to have another adult with you when a
contractor inspects the work to be done.

7/ If you do not get at least 3 written estimates signed by the contractor - not you (do not sign yet) , go back to 1. repeat until you get written estimates signed by the contractor - not you (do not sign yet).

Read the estimates over with some who has some knowledge of the work that has to be done.

This may take longer than you thought; do not rush into it. Research, resaerch research, helps.

When you are ready choose by being informed.

Good Luck

Answer 5

Yes replace them, the old shingles have put nail holes through them. They are the last defence against a leak. You can go over them with new tar paper, but it is best remove and replace. This gives you the chance to inspect the condition of your roof structure. You don't want to cover up problems without knowing what you have up there.

Answer 6

Strip everything down to the bare wood and check out your roof. You may need to replace any bad wood. then start to re roof.

Answer 7

if the shingles are curled or More than 3 layers then you need to remove them if you do you will damage the underlayment and have to replace it

Answer 8
