FAQs

How long does it last?

Usually 25–30 years. You'll likely forget you even had it done.

Do you rip the old roof off?

Sometimes — but often we can lay GRP over the top. We'll confirm after your survey.

Is it really instant?

Yep. No email required. Just pop your roof size in and see your quote.

Can I add insulation as part of my GRP roof?

Yes, but it's important to understand that this likely requires removing the existing roof structure. Doing so increases labour and material costs, and could disturb the ceiling below. Any repairs to the internal ceiling are not included in the standard estimate.
