Flat Roofs & Repairs in Stevenage

Flat Roof Repairs in Stevenage

Post-war homes are common across Hertfordshire, and many have a flat-roofed garage or extension alongside the main pitched roof. TNR Roofing Services repairs and replaces these roofs across Stevenage, covering the SG1 and SG2 districts for both homeowners and commercial clients.

Not every tired flat roof needs replacing. Splits, blisters and failed joints can often be repaired if the deck beneath is dry and firm, and we tell you when that is the better option. When the covering has reached the end of its life, we replace it in felt, GRP fibreglass or EPDM rubber, with new edge trims and outlets so the roof sheds water as it should.

What's included

Flat Roof Replacement in Stevenage

The main parts of the job, each listed in your quote.

  • Full flat roof replacement in felt, GRP fibreglass or EPDM rubber, with the material chosen to suit how the roof is used.
  • Removal of the failed covering and a check of the timber deck beneath, so the new roof is laid on a sound base.
  • Repairs to splits, blisters and lifted joints where the rest of the roof still has plenty of life left in it.
  • New roofs for garages, extensions and dormers, with edges, trims and wall flashings finished to keep water out of the building.
  • Balcony surfaces that stand up to regular foot traffic as well as the weather.
  • Commercial flat roofs, with access and working areas planned so your premises can keep running.

Pricing

Stevenage Flat Roof Costs: What to Expect

Once we have surveyed your Stevenage flat roof, free of charge, the quote reflects whether a repair will do or a replacement is due. Prices vary with:

  • The size of the roof and how easily it can be reached.
  • Whether a targeted repair will do or the whole covering needs replacing.
  • The material chosen: felt, GRP fibreglass or EPDM rubber.
  • The condition of the timber deck once the old covering is lifted.
  • Details such as wall upstands, edge trims, outlets and roof lights.

How it works

How We Work on Stevenage Flat Roofs

What happens from your first call to the finished work.

  1. Free Roof Survey

    We inspect the covering, joints, edges, outlets and any junction with a wall, and check for ponding or soft areas in the deck, so the cause of a leak is clear before anything is priced.

  2. Repair or Replace Recommendation

    You receive a no-obligation quote explaining whether a repair will hold or a new roof is the better choice, and which of felt, GRP fibreglass or EPDM rubber suits the roof.

  3. Carrying Out the Work

    We protect the area around the roof, strip back failed material, make good the deck and lay the new covering with neatly formed edges, upstands and flashings.

  4. Final Review

    Once the roof is finished and the work area cleared, we review the completed work with you and confirm everything has been done as agreed.

FAQs

Common Stevenage Flat Roofing Questions

Can a blistered flat roof be repaired?

Often, yes. Blisters form when moisture or air is trapped under the covering. Small, isolated blisters can be cut out and patched, but widespread blistering usually means water is getting under the roof and replacement is the better long-term choice. A free survey anywhere in SG1 or SG2 will tell you which applies.

Do you fit EPDM rubber roofs on garages in Stevenage?

Yes. EPDM rubber suits garage roofs well, since a single sheet often covers the whole roof with no joints to maintain. We also fit felt and GRP fibreglass on garages in Stevenage where either suits the roof better.

Can you replace the flat roof on a commercial unit?

Yes. We replace commercial flat roofs in felt, GRP fibreglass and EPDM rubber, planning access and working areas with you so the business can keep running. Surveys for commercial premises are free.

Is TNR insured for flat roof work?

Yes. TNR Roofing Services is fully insured with public liability cover and is a Checkatrade member, which means the business was vetted before joining.
