I think if you should ask here: Soil, Compost and Mulch Forum - GardenWeb - methods of composting and using mulches effectively - you will get some opinions.

First of all you only tarp whats really needed these roofing companies get paid by the square footage of tarp they use so there going to use as much as they can second the tarp should be put under the shingles approx 2 rows above the damage and use the least amount of nails to support tarp i cut off what excess of tarp you dint really need with a few nails above cut line you can use felt paper under shingles with nail holes and use roofing caulking to secure shingles

Contract types are frequently interchanged on this forum but are essential to understand as one does not get to treat their build like cost plus in one aspect, and then treat it like fixed price in another aspect. Which is this contract? One doesn’t know for sure but can assume with allowances it is likely a fixed price contract, so in this instance, one is getting a price for the job, not itemized lists of costs. Fixed price contracts can and often do provide fairly detailed bids, but this is not the same thing as the builder opening his books to you. If you want that, then proceed with cost plus. On the topic of markups, expect to pay markup on cost plus or fixed price contracts, as the home buyer should and does on any product they purchase. Trying to remove half the materials from mark-up as frequently suggested on this forum is asking the builder to work for less amount with greater risk. More expensive and complicated materials are frequently more to project manage, more effort in labor and skill to install, and CERTAINLY more risk for the builder should some of these materials need replaced during the build or the warranty period. If one paid markup on $5,000 worth of counter tops but changed to $25,000 worth of counter tops with no additional markup, it’s easy to see how the builder is in a terrible spot if he had to replace $25,000 worth of counter tops on a $5,000 worth of mark-up fee. Simple math really. Mark ups never cover all the potential things that can go wrong in a build, but they are a way to manage risk, which is real in any build. Increasing risk and work load to the builder by adding lots of expensive and complicated materials to manage without correspondingly applying the mark up fee is essentially asking them to take more risk for nothing in return. Many, especially those with sound business sense, will refuse to do it, rightfully so.

Here is a tiny half bath (former closet) where we did an inexpensive update. The previous sink and toilet were too large for the room and the walls were rough and damaged. I added shiplap made the from flooring underlay, a couple of $5 rolls of wallpaper and a shallow vanity on clearance. . biggest expense was a small round front Toto toilet. Big improvement, I think, and if someone wants to change it later it won't be difficult or expensive. The old room was so dingy and awkward to use that I discouraged guests from using it. Now it's cheerful and I smile when I go in there. Do what you like!
