"Great friendly service. Very efficient and clean job. Thanks again"
Complete roof replacement across Portsmouth, Fareham and Havant. New tiles or slates, properly stripped and re-battened, with a 20-year workmanship guarantee.
A roof replacement is one of the biggest investments a homeowner makes. Watertight Roofing gives you a detailed written quote, clear timeline and a 20-year guarantee - no surprises.
Submit a quote request and a real local roofer rings you back during working hours - not a call centre.
Every quote is a fixed total in writing. No hourly rates, no surprise extras after work begins.
Every roof replacement we carry out is covered by our 20-year workmanship guarantee, plus the manufacturer's material warranty so you have complete long-term protection.
Portsmouth's mix of Victorian terraces, post-war housing and coastal properties takes a real toll on roofs - salt air accelerates deterioration faster than inland areas. Shane and the team know every building type across the city.
Real reviews from real Portsmouth homeowners.

"I started Watertight Roofing with one simple rule - if I wouldn't accept it on my own house, it doesn't go on yours. Most of our work today comes from word of mouth and second jobs from happy customers. That's how I know we're doing it right."
If we haven't answered yours, just call - Shane or one of the team will help.
Pick up the phone or fill out the form - we'll call you back the same day during working hours.
