Read the guarantee informationCommon questions.
How do I know whether I need grp fibreglass?
Start with the problem you can see and how urgent it is. JDL will assess the roof, relevant details and access before setting out the appropriate work.
Can photographs help with the first assessment?
Yes. Ground-level or safely taken photographs can provide useful context. A final specification may still require an on-site roof survey.
