Its beautiful but it was a beast to install because the planks were thinner and brittle.

Which may not work trying to marry the new shingles with old brittle shingles.

there is a state test kit that's just $7 or something like that. or at HD, you can get test kits.lead paint is a son of a biscuit. i never test it, hope for the best. i know that's not an excuse, but i paint over it. i think kills would encapsulate pretty much anything.my realtor once said "lead paint just peels in sheets. like wall paper kind of sheets, not brittle like normal latex paint". i have never seen what she described.i dont think i am helping you though... just rambling along.

It becomes brittle and cracks.

Cleaned out a vacant unit today.At the back wall next to the slider doors on the inside is dry and brittle in the pics.Don't see any insects there.Don't know what this is.Any Guesses?

There is also the issue of it being more difficult to install as the shingle is more brittle, and its much easier for the nails to blow through the shingle during install.Temperature isn't the end-all if your roof is completely shot - shingles can be held in a heated tent until they are ready to be installed, handled more carefully, and hand-sealed.

You will be surprised how a broken pipe will hold its form and still work and could be ok for long time but if that spot is cracked it probably means the whole system is brittle and once dug up will just crumble.

(Bonus if you carry some plumbers tape or a few rubber washers in case some have broken or become old and brittle!)

It doesn't get all brittle like sheetrock.
