Gosport sits on a peninsula with water on three sides, and its roofs take weather from every direction. We repair and replace roofs across Gosport, Lee-on-the-Solent and Alverstoke with fixings and details chosen for coastal exposure.

Gosport's housing was built around the naval yards and the forts, which gives the town rows of Victorian and interwar terraces alongside large postwar estates and, in Alverstoke, Regency and early Victorian property on a much grander scale. Lee-on-the-Solent adds seafront bungalows and flat-roofed additions taking wind and salt straight off the water. Exposure is the theme here. With the Solent on one side and the harbour on the other there is very little shelter, and wind uplift is a real factor at ridges, verges and eaves. Salt attacks the fixings and the mortar before it touches the tiles, so a Gosport roof often fails at its edges and its details while the covering itself looks sound from the ground. We specify non-corroding fixings, mechanical dry ridge and dry verge systems where mortar has repeatedly failed, and we check the leadwork properly, because that is where coastal roofs give up first.
On the Gosport peninsula the tiles usually outlive everything holding them down. Nails corrode, ridge and verge bedding crumbles, lead goes brittle and gutter fixings rust through. So we specify for the exposure: non-corroding fixings, mechanical ridge and verge systems where mortar has failed before, and leadwork checked properly rather than patched. Fifteen years of roofing means we know which coastal repairs last and which come back next winter. You get photographs of the failure, an honest view on what needs doing now and a written quotation.
Our experienced team has worked on pitched roofs, flat roofs and roof structures across Hampshire, from minor domestic repairs to full replacements and specialist structural timber work.
We inspect, repair, replace and maintain the whole roof system, from tiles and flashing to timbers, ventilation and guttering, so you never need to appoint several different contractors for one roof.
We recommend the work your roof genuinely needs, never a full replacement by default. Every quotation is clear and written, with free, no-obligation advice to help you decide.
Wind, salt and storm damage drive most of what we are asked on the peninsula. These are the questions that come up across Gosport, Alverstoke and Lee-on-the-Solent.
Gosport, Alverstoke, Lee-on-the-Solent, Stubbington, Hill Head, Rowner, Bridgemary and across to Fareham and Portsmouth. Call with your postcode to confirm.
Yes. Flat roofs at Lee-on-the-Solent and along the front take heavy wind loading, so edge detail and fixing are as important as the membrane. We survey the deck and the perimeter before recommending GRP, EPDM or felt.
We provide the photographs, findings and written report that insurers normally ask for after storm damage, which is usually what holds a claim up. The claim itself stays between you and them.
Yes. We carry out emergency and storm damage repairs, temporary weatherproofing to stop water coming in, and permanent repair once the weather allows. We do not promise a fixed attendance time we cannot keep, so call and we will tell you honestly when we can be there.
It corrodes the metal and breaks down the mortar. Nails and clips give way, lead becomes brittle, ridge and verge bedding crumbles, and gutter fixings rust out. The tiles usually outlast all of it, which is why so much coastal roofing work is fixings and details rather than a new covering.
