Gosport's naval terraces and Alverstoke villas both carry retrofit foam, and both sit in salt air. We strip it back by hand and hand over the evidence your lender wants.

Gosport sits on a peninsula with water on three sides and one road route in at the top. That geography shaped the town: dense Victorian and Edwardian terrace built for the naval establishments and the ferry trade, older Georgian property around Alverstoke, postwar housing filling in behind. Almost all of it stands within a couple of miles of open water. Proximity to the sea is the defining condition rather than a detail. Salt-laden air corrodes fixings faster, coverings weather harder, and ambient moisture in a roof space runs higher than anything inland. Foam applied over that seals the space, so damp sits against the timber year round instead of drying between weather events. The terraces add their own complication, with roof voids running between properties and scaffold access from a street rather than a driveway. Before quoting we establish where the foam stops and whether it crosses into a neighbour's void.
A roof two streets from the Solent does not behave like one in mid-Hampshire, and reading it right is most of the job. Higher ambient moisture, corroded fixings, coverings weathered beyond their age: all of it sits under the foam and none shows until the foam is off. That is why we log moisture readings through the whole strip-out on Gosport property rather than taking one at handover. A lender looking at a coastal property has good reason to ask harder questions, and a record across the job answers them better than a single figure.

We believe in straightforward recommendations, competitive pricing and no hidden costs. Every quotation is clear, with free, no-obligation advice to help you make the right decision for your property.
Salt exposure, terraced access and shared roof voids drive most questions here. The ones below come up on nearly every peninsula job.
We take it. Most household recycling centres will not accept spray foam in bulk, and moving it yourself without a registered waste carrier licence is against the law. It leaves under our own licence and you get the Waste Transfer Note as proof of where it went.
Most UK jobs run two to five working days. Where yours falls depends on the size of the roof, how much foam is there and how easy the space is to access. A small loft with a thin layer of open-cell foam sits at the short end, a detached roof bonded in closed-cell at the long end.
There is no flat rate we could give you before seeing the roof. Price turns on the foam type, how much of the roof it covers, the condition of the timber underneath and how hard the space is to reach. The survey is free, and the written figure it produces does not move once work starts.
We come out and get into the roof space. That tells us the foam type, how far it spreads, the condition of the timber underneath and how equipment will reach it. You then get a written quotation covering the whole job. The survey is free and carries no obligation.
On the peninsula, often yes. Salt air works on the fixings as well as the timber, and a nail that has lost its section will not hold a tile even if the rafter behind it is sound. We report on fixings alongside the timber condition.
It tends to. Higher airborne moisture and faster corrosion of fixings mean rot under foam here is frequently worse than its age would lead you to expect. That is why we log moisture readings across the whole job.
