<p>The existing waterproofing to the classroom roof is single ply. This waterproofing is starting to fail. The main areas of water ingress are the joiners in the classroom pods. These are allowing water into&nbsp;he roof buildup and causing the roof deck to rot. If this roof was to be completely stripped then a full insulated roof system would be required to comply with current regulations. We recommend that the most cost effective solution for this roof would be to peel back the single ply and locally repair the damaged sections of timber deck and then to install a recovery board over the existing roof and apply a 2 layer torch on waterproofing system. We would retain the existing rainwater goods but install a new perimeter trim.&nbsp;</p>

<ul>
	<li>Operatives to apply protective sheeting to work routes and working areas.</li>
	<li>To erect scaffolding to all 4 sides of the building with 60lm of double hand rail.&nbsp;</li>
	<li>To replace 15m2 of existing roof deck and recover.&nbsp;</li>
	<li>To overlay existing roof in 12mmOSB.&nbsp;</li>
	<li>Install GRP drip trims (61m) to perimeter of roof.&nbsp;</li>
	<li>Prime roof using fast drying bitumen primer at a rate of 0.5ltr/m2.&nbsp;</li>
	<li>Install 2 layer high performance torch-on waterproofing system, dressing into perimeter trims.&nbsp;</li>
	<li>Scaffolding to be dismantled.&nbsp;</li>
	<li>Site to be left clean and tidy.</li>
</ul>

<p>Project Note: We have made no&nbsp;provision for any structural works or replacement/ installation of new decking or roof timbers. This quote is based on the scaffolding being erected for a maximum of 4 weeks. Extra hires will be incured if required for longer.&nbsp;</p>
