What's the use of these scraps?
Jeff Howell gave it directly to you, and my garage has a flat roof of asphalt felt covered with stone debris.
These are annoying as they are washed away by heavy rain or blown away in strong winds and also provide a perfect environment for Moss and other plants to grow.
What's the use of these chips?
AC, by email, the stone crumbs on the felt flat roof have two purposes.
First, they act as "loading coats", providing weight to prevent felt from being lifted off by the wind.
This is more important than thought, as the rise of wind on a flat roof may be more powerful than on a sloping roof --
This effect is similar to the lift generated when air passes through the aircraft wing.
In addition to the weight of the debris, the only way to prevent the roof felt from being torn off is to fix the felt bottom coating on the nails on the wood deck, as the wood shrinks, these can work loosely in the past few years.
The second purpose is to provide protection of the sun's rays, which can soften and degrade felt.
Slicer, however, should not be easily blown off or washed off, as they should be carefully embedded in wet asphalt rather than simply dispersed on a dry surface.
If your roof is prone to excessive Moss or other plant growth, then this is usually a symptom of insufficient shedding on the surface of the roof, which is to allow rain to accumulate rather than drain quickly.
A "flat" roof should actually drop at least 1 time in 80 minutes, preferably more.
So it sounds like your problem is not caused by the presence of stone scraps, but by bad buildings.

How to remove bathroom tiles?
How should I remove the tiles from the door pillar partition wall of the bathroom?
I tried to cut them down and when the tiles came off I also removed some plaster and a plasterboard.
CC, Derby's attempt to remove tiles from plasterboard is a laborious task, and one of the huge flaws that goes without saying in modern house buildings.
You have two choices.
One is to leave the original tiles in place and re-Their tiles (
I assume you want to remove the tiles in order to replace them with a different pattern or color)
For this purpose, there is now specialized tile cement on the market.
This is still a hard job because there is no "suction" on the surface of the original tile and the new tile slides on it.
In addition, the increase in wall thickness can make things around the bathtub, basin and shower tray awkward.
Another option is to bite the teeth and tear off the entire area of the gypsum board.
Use water instead of replacing it with more plasterboard
Wear-resistant cement board (
For example, Aquapanel of Knauf can be bought from DIY store)
In wet conditions, its performance is better than plasterboard, and may even give future generations of DIYers an opportunity to remove the tiles without damaging the substrate.
Do I need to install the inhibitor?
I read your recent review (Nov 18)
Regarding damage to the water softener and the alleged boiler.
Please let me know
If my central heating system is filled with soft water through a water softener, do I need an inhibitor?
By email, DS is definitely.
The purpose of the inhibitor is not to prevent the formation of scale
From hard water, but to prevent corrosion, corrosion occurs mainly through the combination of different metals (
Copper, steel, casting
Iron, zinc, lead)
Connected by an electrolytic medium of water.
This can cause your central heating system to run like a car battery, the metal to slowly erode, and hydrogen is produced as a by-productproduct.
Inhibitors prevent this from happening.
