How Long Does a Commercial Roof Repair Take in Dorset?

Minor repairs in Dorset like sealing cracks or replacing a few shingles can be completed in a few hours to a day, while moderate repairs requiring flashing replacement, drainage improvements, or leak repairs may take one to three days in Dorset.

When Should You Repair vs. Replace a Commercial Roof in Dorset?

Deciding between commercial roof repair in Dorset and full replacement depends on the extent of damage and long-term cost-effectiveness.

Repairs are sufficient when the roof structure is intact, damage is localised, and leaks or cracks are minor in Dorset.

However, if the roof has widespread leaks, severe material deterioration, or is near the end of its lifespan, a full replacement in Dorset may be more cost-effective in the long run.
