Re: Structural evaluation
Dear Scott and Lisa:
This letter is in reference to the partially completed roof addition and other work at 6296 Hwy. 82
near Glenwood Springs, CO. The following comments are a result of a July 19th field visit and
follow up calculations. As background information to the reader of this letter, the new roof was
constructed entirely above an existing roof which leaked for obvious reasons. At the time of the
field visit, the rafters, plywood and roofing were complete; the walls which frame up to the new
roof were not constructed. The old roof will eventually be removed and the under side the new
roof will become the ceiling for the living space. Snow loading for this area is 40 psf.
The Roof Structure
The following comments pertain to the roof only. It is assumed the roof loads will transfer to the
foundation m the same manner as the old roof.
The roof structure (work completed before July 19th) is not adequate for the following reasons:
The 6x6 beam spanning 6'-6" which supports the north-east comer rafters is not capable of
supporting the roof rafters, Additionally, the north support for this beam is precariously
positioned on the column below. It is assumed that when the work is complete, framed
walls will extend to the under side of the beam rendering the beam unnecessary.
❑ The 3 1/2"x9 112" Paralam supporting the west edge of the roof is over -stressed where it
cantilevers 8 ft. at the north end of the house. Again, when the work is complete a wood
column in the framed wall below will support the cantilevered end of the beam thus
eliminating the problem. It is anticipated the wood column will transfer load directly to
the foundation.
❑ The 3 112"x9 1/2" Paralam supporting the west edge of the roof is over -stressed where it
spans 20 ft. The Paralam is only capable of supporting a span of up to 14 ft. Fora 20 ft.
span the beam should have been a 3 1/2"x14" deep Paralam. To correct this problem, it
may be possible to sister another 3 112"x9 1/2" Paralam to the existing if the supports are
properly framed.
❑ The 3 1/2"x9 1/2" Paralam is not recommended for exterior exposure. The south end of
this beam should be wrapped with weatherproof material.
❑ Due to the manner in which the new roof was extended above the existing, there is
currently very little lateral force transferred from the new roof to the house below. Lateral
forces are a result of wind applied to the structure; these forces are normally transferred
from roof to foundation via the sheathing in the walls, floor and roof At this point in time
the lateral loading on the new roof is small and the old roof is acting as a lateral diaphragm
distributing the wind load to the walls below.
When the old roof is removed and the ceiling is extended to the height of the new roof,
care should be exercised to ensure these wall diaphragms are continuous from the original
walls to the new roof above. The new walls should be sheathed with 1/2" plywood.
Ideally, the plywood should lap 1'-O" min. over the framing of the • original walls below.- -
Alternatively, mechanical connectors or strapping may be used depending on the situation.
I am available to discuss options in more detail. Likewise, the connection of the wall to
the roof above is critical. Simpson A35 clips should be installed at every 3rd rafter along
the east and west sides of the house. Along the north and south sides of the house, either
blocking or a continuous rafter should be used to positively connect the roof to the walls.
❑ Before the new roof is insulated, consideration should be given to how the new structure
will be ventilated. For cathedral type ceilings it is common to provide a 1" airspace for
positive air flow between the insulation and plywood of each rafter space. Soffit vents
between each rafter would also be required. Check with the building department to find
out weather or not rafter ventilation would be required. There are many philosophies
regarding the need and method of ventilation.
Enclosed Addition
Regarding the enclosed addition on the north-west corner of the house:
A 6x6 timber beam supporting 8 ft. long floor joists (no roof) will span up to 6 ft.
maximum. For this same loading condition, 2-2x12's will span 12 ft. max.
Foundation Comments
The posts along the west edge of the house have no foundation. As we discussed during
the field visit, it would be beneficial to construct a solid foundation for these columns. I
normally recommend 2 ft. sq. pads founded 3 ft. below grade. However, because
excavation in the rock would be very difficult, I recommend pouring concrete pads
directly on the rock at or around 1 ft. below grade. Since the pads would not be frost
protected, a certain amount of frost heave should be anticipated.
The concrete pads should be 1'-8" square x 12 inches thick reinforced with 3-#4 rebar in
each direction. The rebar should be 3" clear from the bottom of the footing. If the pads
are founded on sloping rock then four #4 rebar x 1'-0" long should be doweled into the
rock 6" minimum. Simpson connectors are available to connect the wood post above to
the concrete pad.
Because it is difficult to cover every detail necessary in letter form, I recommend a follow-up
field visit either during or near the completion of the work.
Should you have any questions, please call.
Sincerely,_..
Ernest Kollar, PE
