<p>Further to our recent site visit please see the below quotation. We are concerned here with one roof leak in an office,the stained ceiling tile corresponds with the edge of an inverted felt roof, by a doorway leading onto another roof area weathered with a standing seam roof sheet, the standing appears in good order. The jamb and header around the door way are suspect as it is the associated mastic sealants which are in poor order. Replacing these may solve the problem, but as a precaution the checker base plate in the doorway should be lifted to enable the area below to be inspected and a small section of the inverted roof cleared to expose the felt membrane.</p><ul><li>Operatives to apply protective sheeting to work routes and working areas.</li><li>To attend site to replace 3 no defective drip flashings and 1 no flat jamb flashing with new, purpose made flashings manufactured from 0.7mm thick galvanized steel with a protective metallic silver colour coated finish to match the existing.</li><li>To install new sealants, low profile carbon-steel fixings and pop rivets (metallic silver finish). These were measured up during our initial visit.</li><li>To expose a 6sqm section of the inverted felt roof immediately outside the doorway, removing and setting aside pebbles, paving slabs, filter membrane and insulation, inspecting the felt membrane for any defects. If any defects are found then we can carry out minor repairs then and there by cutting out and re-sealing blisters, then priming and applying by gas torch a suitable felt patch, any defective laps can be repaired in a similar manner.</li><li>Upon completion replace the insulation, filter membrane, pebbles and slabs.</li><li>To lift the base plate in the doorway, inspect the area, repair if practical any defects found then replace the base plate.</li><li>Site to be left clean and tidy.</li></ul><p>We would use our best endeavors&nbsp;to trace and cure the current problems and we will report back with our findings, if the leak persists then more extensive investigations/ repairs would be required on which we would advise.</p><p>Our total cost to carry out the above works in&nbsp;normal working hours shall be</p><p>Labour - &pound;560.00 (2 Operatives)</p><p>Materials - &pound;970.00</p>
