<p>As per ASRG quote ref: Q/11542/RGH</p>

<p>Specification<br />
To engage a roofing consultant to undertake an electronic leak detection test to the roof area,<br />
marking up defects as the test progresses and providing a photographic report upon completion.<br />
To have one roofing operative in attendance, to assist with the survey and to carry out suitable and<br />
durable repairs to all minor marked up defects, i.e. defective laps, small splits or damage to the<br />
membrane.<br />
Defects being repaired using an Eternabond &lsquo;single ply&rsquo; patch repair kit, the area being wiped clean<br />
then cleaned again using a spray applied EternaClean, applying Eternabond Primer and allow to<br />
cure, then applying EternaTape, all being applied in accordance with the manufacturers instructions,<br />
we allow for up to 12 no patch repairs.<br />
Safety harness with 15m lanyard being worn for inspection / works within 2m of any exposed<br />
eaves, these will be connected back to the existing roof mounted safety line.<br />
Total Cost: &pound; 925.00</p>

<p><br />
Please Note: We have assumed that the leaks are caused by minor defects that can be repaired<br />
during the course of the day, should more involved works be required we shall provide you with a<br />
specification and quotation.<br />
Likewise, if the consultant considers the roof to be nearing the end of its useful life, we shall<br />
provide a quotation for its refurbishment.<br />
We shall use our best endeavours to check the entire roof area, but areas underneath roof plant,<br />
solar panels or the like</p>

<p>Price from SOS Leak Detection</p>

<p style="margin-bottom:13px">We propose a tracer gas survey is carried out which involves use of a harmless mixture of Hydrogen (5%) and Nitrogen (95%) gas mix into the external elevation/underside of the roof areas to the affected area to be tested. The Nitrogen is used as a carrier for the Hydrogen molecules which will gradually rise and permeate through the external construction in the area(s) of leakage. Electronic detection equipment is then used either externally or internally to locate the Hydrogen molecules. The suspected area(s) of leakage are then recorded within our final report.</p>

<p style="margin-bottom:13px">In addition we may utilise a thermal imaging camera as heat sensitive areas can be located or areas of water ingress where water maintains its heat through thermal capacitance. The area of highest water concentration is often the point of entry. Flood testing may also be employed and simply consists of using a hosepipe to concentrate water to an area of suspected ingress and can be enhanced using a tracer dye. A water source will need to be readily available to carry pressurised water to the roof surface.</p>

<p style="margin-bottom:16px">Our fee for the investigation works would be &pound;1395.00+VAT and is inclusive of two surveyors for a full day and the preparation of our final report which will detail our findings and recommendations.</p>
