Average from 17 reviews on Google
- High standard of work
- On time
- Leaks sorted
- Polite staff
Altitude came recommended and lived up to it: quick to respond, polite and fairly priced. They put right a large shed roof that another company had already had two goes at.
Great from first call to finish. Jordan took the time to explain what was behind the cold spots in the house, kept us updated throughout, and the roof work itself was done to a high standard.
I had water coming in around the chimney and some very expensive quotes elsewhere. Jordan was honest, explained exactly what the repair needed and broke the cost down clearly.

FAQs
Roofer Portsmouth FAQs
Answers to the questions we are asked most often about roofing work in Portsmouth.
How much does a roof repair cost in Portsmouth?
It depends on what has failed and how easy it is to reach. A few slipped tiles that can be reached safely cost far less than a repair that needs scaffolding, new lead work or a section of underlay replacing. The type of tile or slate, the pitch and height of the roof all make a difference too. We look at the roof first and give you a free, no-obligation quote with the work explained, so you know exactly what you are paying for.
Do you offer emergency roof repairs in Portsmouth?
Yes. If a storm has lifted tiles, your ridge has come loose or water is coming through a ceiling, call us on 07525 253333. We will make the roof safe and watertight first, then come back to carry out a proper permanent repair once we know the full extent of the damage.
Which areas do you cover as a roofer in Portsmouth?
We cover the whole of Portsmouth, including Southsea, Fratton, North End, Copnor, Milton, Eastney, Cosham, Drayton and Paulsgrove, plus the surrounding towns such as Portchester, Fareham, Gosport, Havant, Waterlooville and Hayling Island. Our base is in Portchester, so the city is right on our doorstep.
Should I repair or replace my roof?
If the roof covering is generally sound and the problem is local, such as a few broken tiles, a failed flashing or a loose ridge, a repair is usually the sensible choice. When tiles or slates are failing across the roof, the underlay has perished or the battens are rotten, repeated repairs stop being good value and a replacement makes more sense. We will tell you honestly which applies to your roof.
Can you repair a leaking flat roof?
Often, yes. Splits, blisters and failed upstands can be repaired when the rest of the covering is in good condition. If water has been getting in for a long time and the deck underneath has gone soft, re-covering the whole roof is the longer-lasting fix. We check the deck as well as the surface before recommending either option.
Are your roofers qualified and insured?
Yes. Our roofers are trained to NVQ Level 2 in Roof Tiling and Slating and hold CSCS cards, with SMSTS and SSSTS site safety training. We are fully insured and carry out work in line with the Construction (Design and Management) Regulations 2015.
Do you provide free roofing quotes?
Yes, quotes are free and there is no obligation. Call 07525 253333 or use the Request a Callback form and we will arrange a convenient time to look at the roof.
How long does a new roof take to install?
It depends on the size and shape of the roof, the materials, access and, above all, the weather. A straightforward re-roof on an average house is usually measured in days rather than weeks once the scaffolding is up. We will give you a realistic timescale with your quote and keep you updated if the weather changes the plan.
Do I need planning permission to replace my roof?
Like-for-like re-roofing does not usually need planning permission. Listed buildings and properties in conservation areas can be different, and replacing a large area of roof can bring Building Regulations into play. We will flag anything that could apply to your property before any work starts.
Do you work on commercial roofs as well as homes?
Yes. Altitude Roofing South Ltd works for homeowners, landlords and commercial customers, on pitched roofs, flat roofs and cladding.
