The Old House WebGutter Lining System is a custom made gutter lining system.
Wood framed supporting structures are used to build copper gutter linings.The copper lining should not fit tightly.The lining needs to be free to move.Positive drainage can be provided by the bottom of the frame.The inner edge of the lining should not be more than 2 inches above the outside edge.
The maximum length of copper linings should be 10'.The sheets have to be pre-tinned.Adjacent sheets are joined by riveted and soldered seams.If the gutter's girth is more than a sheet of copper, the cross seams should not be larger than the sheet width.
Expansion joints are placed at intervals.Table 10B shows the spacing of expansion joints and downspouts.If the gutter lining forms the leg of an inside or outside corner, expansion joints should be provided within a short distance of the downspout.The expansion joint should be constructed at the corner itself.
The lining of a wood box gutter frame is shown in special conditions.The edge strip can be secured to the masonry cornice with brass screws and lead shields.The edge strip is secured into the reglet with lead wedges and sealant.
For ease of soldering, built-in gutter should be fabricated outside of the gutter framing to allow soldered seams inspection and watertightness testing prior to final gutter system installation.
There is a one piece copper gutter lining and apron design that is suitable for use in areas with ice or snow.There is an apron on the roof.
If the lining meets the wall, provide at least 1/2 for expansion.Section 1 shows the dimensions, along with two methods of flashing.In areas with ice and snow, Method A shows a typical end condition with an expansion joint cap.In areas without ice and snow, Method B is used.
Section 2 shows a flashing method for the apron that rests on the roof.
A strip of 20 ounces.Cold rolled copper is attached to the gutter frame with copper nails or brass screws.The copper gutter lining hooks over the edge strip.
Expansion must be accommodated at the corner in this detail.The copper gutter, apron and flashing are not shown.The roofing extends beyond the edge of the apron.The corner has to allow movement in the copper linings.It is covered with a cap.The copper angle divertor is soldered onto the cap.
The copper lining and apron is shown.The apron is secured with cleats.It is suitable for areas with ice and snow.
Table 10B has more information on required dimensions.
There are various components at the outside corner.The expansion joint cap is placed on wood and folded over.The hip flashing is soldered into the upper edge.
Continuous copper cleats are used to secure the gutter lining in place.The cleat is anchored to the wood blocking with nails.There is a cleat just below the roof.The copper roofing system and gutter lining are closed with a stiffening ridge on a copper panel.The lock-strip is soldered to the gutter lining at the lower end of the panel.Potential leaks into the building can be prevented by the top of the gutter lining being higher than the front edge.
The only difference is that a continuous reglet is used to anchor a cleat.The installation of the gutter lining can be simplified if wood blocking is eliminated.The cleat is inserted into the reglet, held by lead wedges and sealed, or fastened with bronze screws and expansion shields.
