Last February 2009 after the heavy snow the bitumen roof sheets on my
roof distorted directly above my Radial Arm saw position with the consequential water penetration.
This being the result. Taking down the celotex boards exposing the bitumen sheets.
I have stuck a paper clip into the joint in an attempt to highlight the defect
The saw is central to the workshops length so theres not much natural light therefore I leave the door open which can be a bit cold in winter.
This gave me an opertunity to install a roof light. The roof light is basicaly a ply box with a 2" x 1" frame screwed to its top.
A seperate hinged frame on top rebated to take double glazing
The hole is cut and the box inserted injecting ezpanding foam as temp weather proofing till I stripped the roof sheets.
View from beneath with box fixed
Ditto from above
The sheets are then stripped and insulation installed.
Ply deck laid
Counter Flasings fixed
The box is then flashed
Roof deck painted with bitumen paint and sheete replaced
And then double glazed. I did not change the rest of the roof as we had some pretty severe weather, lots of heavy rain and the workshop was snuff dry untill December the week before Christmas when it snowed
Unfortunatly we went away coming back this March to a flooded South East and I was left with another mess in the workshop to clear up and repair, Therefore I stripped the whole roof half the area at a time and completed what I should have done last year.
These are the processes. Deck, First coat of bitumen, second coat, Flashband and the finished roof. I think this is an easier way of applying a cheap roof covering other than the preferred hot laying of three layer roof felt. Lets see how long this method lasts. Fingers crossed. (As I speak outside the thunder is crashing and the lightning flashing and the rain is coming down in buckets)
