Pier and Beam Wooden Framed Foundation
A common misconception about this type of foundation is that if it is some-what old-fashioned type but believe it or not in a highly-competitive real-estate environment; builders prefer this type just to stand-out with a positive impression on homebuyers because of aesthetics and amnesties of raised floor homes.
In Pier and beam wooden framed foundation, as the name suggests, involves assemblage of girders, floor joists and floor sheathing that raise the floor of the building off the ground.
Pros

1. Allow fast construction; as it did not involve lengthy concrete slab delays due to poor weather, formwork fixing and curing.

7. Because it does not involve heavy digging; so no machinery needs to be hired and you can construct this foundation by going DIY as just 2 or 3 persons can do the job.
8. As the floor of this building is elevated above the ground so there would be no problem of dampness or pests etc.

Structural Slab Foundation

1. The wooden raised floors are bouncy and are sound making which are sometimes very annoying for the occupants. The floors require regular maintenance as sometimes they become saggy and deflected.
2. For the concrete slab floors there are minimal chances of drastic damage from termite and even you don’t have to call for the mold removal services.
3. With the concrete slab you don’t need to have insulation under the floor but for pier and beam wooden framework foundation you have to insulate the floors properly.
4.

The Bottom Line.
You would now be at ease with the selection of foundation type; but keeping in view the dictating and deciding factors we recommend you to hire services of a qualified professional firm that would be observing your site situations and your requirements.
But remember, not all structures are perfect and all have a life even if of 100 years but never expect that you would be in no need of repairing and refurbishing.

You are living in a zone of hefty rains and dense snowfall and that’s why you have this pitched or slanting roof above you. This is because you know that the best way to avoid ingress of precipitation is to drain it away as quickly as possible.

What if you were shown that regardless of having these lofty slopes, your roof is inundated by snow dams and water ponds? And icing-on-the-cake is that the culprit is chimney, the stack which vents out hot smoke from your home.

When would you require a chimney cricket on your roof?
When the chimney of your house is located at downward slope of your roof and is more than 30 inches in width; it is likely to form a chimney roof valley. This valley if left unattended would allow the seeping water to accumulate.
This accumulation is perilous for masonry of the chimney as well as for your roofing system. As this area is behind the chimney wall it is therefore least noticeable from the ground; because of this reason it is mostly overlooked by the property owners and realtors. The situation would even get worse when the temperature drops and in the time when the water pond behind chimney freezes.
Roofing experts have been using a remedy and a trick for avoiding it and shedding the rain water, snow and debris with the help of a raised and little crested roof top called a Chimney Cricket. This Chimney cricket (also termed as saddle) is introduced on the higher side i.e. the back side of the chimney. Depending on the type of material from which it is built; there are several types of chimney crickets.

In ordinary circumstances, the cricket can be built with aluminum, stainless steel or galvanized steel in a triangular shape in cross-section with sides angled in a way to divert / glide the splashing water. Although as a guideline it is recommended to have a chimney cricket even if the width of the chimney wall is less than 30 feet. There are many factors that contribute and you always don’t want to replace the complete roof assembly just by saving few bucks initially.

Importance of Flashing around Cricket of Chimney Roof Valley
Now that you have cricket on your chimney roof valley and still a property inspector informs you that you need complete roof repair due to damage done by the ingress of water and poor roof drainage. It is because the cricket of chimney roof valley has leaking spots and that is just because of improper flashing around the cricket-chimney-roof joints.

What is chimney flashing?
In the simplest of meanings, the flashing is the metal sheet that overlaps the roof chimney treatment and makes it watertight. In case of a chimney guarded against leakage by a cricket the problem with faulty flashing even makes it worse for you. The roof inspection for faulty flashing would be difficult to diagnose in such cases.
It is therefore of utmost importance, to use multi-layer flashing or step flashing in a section lapped up. In the absence of such a flashing, your roof sheathing and the ceiling below would be in a big irrecoverable trouble.
We recommend you to use flashing and counter-flashing, the metal sheet is woven with the shingle course and is then lapped with the side of the chimney followed by counter-flashing. In which metal is fixed with the chimney masonry joints and is overlapped with the previous step flashing.
​
Although in most of the areas, the flashing is carried out by galvanized steel and aluminum sheets but if your budget allows you can use one made of copper which has a longer life span. It actually depends on the type of area you are living in, your budget and the easy availability of flashing material.
