I have a 30 year old home with a cement tile roof. the tiles are brittle and the roof would need to be repointed and rebed with new valleys put. The cost would be approx $5,500. i do not want to pressure clean the roof as i have new insulation in the roof and dont want it to get damaged during the pressure clean.
Should i repoint the roof as above or should i re-roof with colorbond which would include the sarking and flashing but it woukd cost approx $18,000 but has a 40 year warranty.
