Whitchurch sits on the River Test, where valley damp makes a sealed roof worse. We take the foam off by hand and record the damp evidence your lender will want.

Whitchurch grew on the River Test around milling and silk weaving, and the silk mill still runs as a working museum. The town kept a good deal of older property, much of it altered and extended repeatedly over the last two centuries, which means a roof here is rarely one uniform structure. The Test valley is the reason moisture matters more in this work locally. Air near a chalk river carries more humidity than the downland above, and roof spaces in the valley run damp year round. Foam that seals such a space does not keep water out, it keeps it in, and the timber stays wet between cold nights instead of drying. Where a roof has also been extended at different dates, the foam may only cover part of it and the rest may be a different construction entirely. We survey the whole space before quoting so the price covers the roof as built rather than as it appears from the hatch.
A single moisture reading at handover tells a surveyor very little about a Test valley property. Humidity here is high enough year round that the useful evidence is a record across the whole job, showing what the timber was like when we exposed it and how it responded once the roof could breathe again. We log that throughout rather than at the end. Reading a roof that has been extended three times over two centuries also takes a roofer rather than a foam contractor, which is what fifteen years of Hampshire roofing gives us.
