Sealing Metal Roof Leaks

To the left a roof sealing in process.

A metal roof does not require a coating application to be leak free.

During the sealing application process a fluid applied seamless membrane is installed at every potential water entry point.  Fasteners, penetrations, transitions, ridge cap, and rake trim, are common roof areas requiring sealing.

Two coats of  acrylic coating is an classical example, however, if the budget isn’t sufficient, a sealing application can be a very good option.

Spot Sealing

We can provide a cost effective solution to stop a single persistent metal roof leak. Our vast experience has taught us the methods that work. With our test knowledge, we know which high grade polyurethane sealants and roof coatings that can stop the leaks panels.

Replace the roof or waterproof and coat? Cut and Paste.

When replacing a metal roof, some areas can be restored, and others require changed.   In the above, part of the metal roof was rotted out, and replaced with new panels.   The remainder waterproofed and coated.  Skylights were also replaced.

Metal roof coatings

The metal roof coating process includes arresting any rust, protecting the sealing products, and extending the life of your metal roof.

In addition, the coating provides a bright, fresh, new finish which has a high level of solar reflectivity.   We provide warranties up to 5 years.   Tough enough for metal building leaks.

Metal Building Renovation – From abandoned

to clean, bright, productive space!

The above services include steel replacement, industrial metal building painting, and insulation replacement.

Our metal building renovation projects range from simple inexpensive small projects to complete building renovations.  Before we begin some renovations the question being considered is should I tear down the building and start over or should I renovate it.  Also, we always put safety first.

When replacement panels are necessary, we know who to call.  We work with over 10 different metal building component manufacturers, if the profile of  your metal wall or roof panel is still being produced, we know where to find it.  We also know how to adjust if it is out of production.

Sometimes it is desirable to alter the structure of your building.  In the above, the end wall was aligned with the flow of the railroad track before we squared it off.  It had been angled to accommodate an old train track.

At completion, the renovated building looked like new, and at a fraction of the price of replacement!  Also, it can be completed in a fraction of the time, without the hassle of all of  permits required with new construction.

TYPICAL INSTALLATION

Concrete Floors Above D.P.C. Level

Cover concrete floorslab with a suitable damp proof membrane, ensuring adequate coverage at joints. Membrane should be taken up vertical surfaces to finished screed level. KIMMCO Building Slab is laid directly on top of the damp proof membrane with edges close butted and joints staggered. Edge insulation consisting of strips of insulation not more than 2.5 cm thick cut from standard slab with a width to suit the specified screed thickness should be placed vertifically against the walls, the bottom edge resting on top of the horizontal

and vertical insulation with care taken to ensure that laps are well covered. It is recommended that the screed should be 60 mm thick with a galvanised mesh reinforcement laid into it.

Cavity Walls

Use galvanized, stainless steel or nylon hangers with retaining washers for holding the insulation in correct position.

The 2″ FSK overlap of Building Slab to be positioned at the bottom of each slab in order to cover the top of the underlying slab to protect the insulation from accidental water spilling during the outside wall construction.

Cavity Walls With Ties

Construction methods are only slightly affected by the use of Building Slab. The inner leaf of the wall construction should be cleaned of mortar protrusions before fitting Building Slab between each horizontal run of wall ties. Mortar droppings should be removed from top edges of insulation before placing the next row in position. The insulation must be placed against the outer face of the inner leaf of the wall. A minimum air gap of 1 cm should be left between the insulation and the inner face of the external wall leaf. This ensures normal drainage and ventilation of the cavities. Joints between insulation slabs must be close butted with all vertical joints staggered.

Building Slabs are held back against the face of the inner leaf by the drip prong of the wall ties, special clips or adhesive. In applications using marble or stone facings, it is important that the facing be tied back to the main structure, the ties to be inserted at joints between the insulation. Type and frequency of fixing depends on size and weight of facing material specified.

Solid Wall Construction

Insulation can be applied to the back up wall in one of the following manners:

A. Batten out surface of wall to suit width of slabs ensuring that Building Slab can be fixed snugly between battens without gaps. Apply a vapour barrier over the Building Slab, fixing it to the battens with staples or flat head nails. Vapour barrier to be applied horizontally with each run overlapping previous by at least 15cm. Fix expanded metal, galvanized chicken mesh or plastic netting over the vapour barrier as a key for the rendering, fixing it into the vertical battens by staples or flat head nails. Some additional fixing may be required between battens to remove excess bellying. Apply external render coats or plaster board.

B. Apply foil faced Building Slab to the wall with recognized mechanical fastenings such as Hilti using large head washers. Insulation should be applied with staggered vertical joints. All boards to be close butted. Apply expanded metal, galvanized chicken mesh or plastic netting over the insulation using mechanical fasteners. External rendering or other facing can now be applied.

C. We recommends that metal wall ties or wires be used to tie the external wall finish (marble or stone) to the internal wall. This gives additional stability to the structure. Care should be taken to ensure that the wall ties are long enough to reach from the internal wall through the insulation to the external finish.

Concrete Roofs

The roof surface should be clean and dry. A perfectly smooth surface to the concrete is not necessary but care should be taken to ensure the boards do not rock.

Building Slab should be bedded in a bitumen compound on top of an approved continuous vapour barrier with well lapped joints. Weathering treatments should be laid in accordance with manufacturers instructions.

A reflective surface finish should be applied to reduce absorption of solar heat.

Building Slab can be used with synthetic membranes by sticking, in accordance with the membranes manufacturers specifications.

Metal Roofs

Building Slab may be applied to metal roof decks by bitumen adhesion or by mechanical fixings. For bitumen compound on top of a continuous vapour barrier, care must be taken to ensure that joints between boards are supported by the deck profiles and are not laid with the open flutes running continuously beneath. It is recommended that the insination be placed at a 45 deg. angle to the line of the deck flutes.

For mechanical fastening, one of several methods may be used, i.e. Lexscuco clips or screw and washer fixings. Washers should be 50 mm in diameter with a large countersink cup so that screw heads do not protrude above insulation.

False Ceiling

Falls should be incorporated in roof deck construction by contractor.

Access Roofs

Building Slab laid directly beneath weather proofing such as built up roofing is suitable for roofs carrying normal light maintenance traffic. A finish of concrete tiles or similar should be applied where continuous foot traffic is expected.

Building Slab should not be used for roof decks where heavy point loadings can be expected or where vehicles of any type will be used.

TYPICAL FIXING DETAILS

Wall construction of light weight metal sheeted buildings are frequently uninsulated, leading to extremely uncomfortable working conditions or excessive cooling requirements. Building Roll can be fitted to new and existing buildings to alleviate these problems.

New Construction

Building Roll is fixed at the head of the wall and allowed to drape down the length. The insulation roll may be fixed to sheeting rails with the faced side to the inside of the building if no lining sheets are to be used or alternatively by trapping the insulation between external and internal sheeting. Spacer bars of non compressible material should be used to prevent undue crushing of the insulation.

Existing Buildings

Building Roll may be installed from within existing buildings by using a “T” bar suspension gride and liner sheets, the insulation can be cut to suit the size of lining sheet and fixed to the back of the sheet with adhesive or mechanical fasteners. The lining is then installed in the grid system in the normal manner.

As an alternative to the above, timber packing strips may be cut to suit the sheeting rails and screwed in place, fix the Building Roll at the head of the wall by screws into the timber packer with a steel strip placed on top of the insulation directly over the packer. Repeat as required at other sheeting rail locations, ensuring that the Building Roll are closely butted to each other with the edge flanges overlapping.

Over Purlin Application

Fix end of Building Roll faced side down, at ridge and allow to unroll to eaves. At eaves, roll should be cut and pulled taut. Each subsequent roll should be overlapped or butted to avoid gaps.

Packing strips, equal in thickness to the insulation, should be placed along the line of each purlin and fixed through the roofliner to the purlin below. This avoids undue compression of the insulation.

The roof cladding should be carried out in conjunction with the insulation work to avoid accidental damage. Fixing should be through the crown profile of the roofing sheet and down through the spacer to the purlin below.

Weathering sheets should be fitted as insulation, work progresses in order to avoid unnecessary damage to the insulation. Holes for hook bolts sealed against water penetration.

Under Purlin Application

After application of roof covering, the internal lining and insulation can be carried out using a framework of light metal “T” sections suspended from the purlins by straps or hangers.

a) Cut Building Roll to size and lay on lining board. To assist in handling, the insulation may be adhered or stapled to the lining board. Erect lining board and insulation within the metal T grid securing as required.

b) Alternatively, the insulation can be applied from rolls initially secured at the ridge and allowed to unroll progressively towards the eave in conjunction with the application of lining boards. It is important that the adjacent layers of insulation are sufficiently overlapped to prevent heat loss or gain.

Sandwich Construction

Roofs which incorporate double sheeting can be easily insulated with KIMMCO Building Roll due to its flexible nature. After initial fixing of the inner or lining sheeting, KIMMCO Building Roll should be fitted by unrolling from ridge to eave, ensuring that each subsequent roll overlaps or butts the preceding roll to eliminate gaps and maintain the effective insulation values desired. Fit spacers in the form of timber battens or proprietary profiled strips or other compression resistant materials on top of the insulation directly over the purlins to avoid crushing the insulation when the external weathering sheet is fitted.

DEMOUNTABLE PARTITIONS

Generally, factory assembled with metal or plasterboard facings. The addition of KIMMCO Building Roll to the partition void reduces the level of sound transmissions.

“A” Purpose Built Light Weight Partitions

Due to the problems of load and the usual involvement of wet trades, heavy block partitions are commonly being replaced by purpose built light weight partitions. With careful design and construction, these partitions can provide adequate levels of sound transmission reduction.

Partitions should be constructed with as little mechanical linkage as possible, studs should be staggered to avoid direct transmission paths, with the insulation fitted or woven between them.

“B” Sound Absorption Treatment

In areas where sound absorption is required, KIMMCO Building Roll can be used to line the walls, behind a decorative or functional facing which will permit the passage of sound waves to the glass wool behind, thereby reducing the amount of sound reflected back. This type of treatment is commonly used in open plan offices, auditoriums, sports halls, sound studios, multi-purpose school halls and industrial areas.

The insulation should be fitted directly against the wall surface, between timber battens. A surface treatment of perforated hard board or sheet metal can be fixed to the timber battens. The area of perforation should be no less than 10% for most common treatments, though a 33% perforation is preferable, as this gives an optimum amount of absorption. Should a more decorative treatment be required, a good quality curtain grade hessian or other decorative fabric can be applied.
