If there are no roof windows (opening these is the quickest and easiest way of providing ventilation in a loft) then follow the loft floor along to the point where the roof comes down to meet it. Quite often when remedial work is being carried out such as installing additional loft insulation or fitting PVC eaves cladding. This amount includes seller specified domestic postage charges as well as applicable international postage, dispatch, and other fees.

Well it’s true and I know because I worked as a roofer for 17 years and have fitted this product to hundreds of lofts but you don’t need to pay for a roofer.

I will use a bathroom as a comparison: What do you do after you shower and there’s condensation over the walls and windows in your bathroom? This can often be remedied quickly and easily if your loft has a traditional lapped membrane or roofing felt behind the tiles.We ask an expert with qualifications or extensive experience in the relevant area to fact-check and review the content, which we update accordingly, if applicable. Lofts shouldn’t be damp or smell musty and I’ve found that such issues are usually a sign of a roof leak, ventilation problem or other faults that will need investigating.

If you’ve got condensation issues in your loft it’s now relatively easy to resolve by adding additional loft ventilation. This is usually due to missing insulation under the roof tiles which causes cold spots where condensation forms. However if you’ve added anything that could have made the loft area cooler (such as increasing loft insulation) or reduced the effectiveness of the existing ventilation (such as fitting insulation that partially or completely blocks existing vents) then you’ll probably need additional ventilation.

These are the same tiles that provide a terminal for soil vent pipes or mechanical extraction units most commonly bathroom extraction.An incorrectly installed vapour barrier can cause condensation spots on the ceiling and I have seen cases where the condensation in the home went up after the barrier was fitted.
