Know your roof
A layered roof built for low slopes.
Modified bitumen is an asphalt-based roofing system used on low-slope buildings. Reinforced sheets form the roof covering, with seams, flashing and drainage playing an important role in keeping water out. Lotus repairs and replaces these systems across DFW.
Roof replacement
Review the existing assembly and specify preparation, layers and installation for the chosen system.
Roof condition reports
Document visible wear, drainage concerns and maintenance needs to support building decisions.

Leaking flat roof?
Repair starts at the source.
Open seams, worn surfaces and damaged flashing can let water into a modified bitumen roof. Lotus inspects these trouble spots and recommends repair or replacement based on the condition of the roof.
Schedule a roof inspectionSeams, surfaces & flashing
We check for separation, splits and damage around edges, drains and penetrations. Localized defects may be repairable when the surrounding roof is sound.
Water below the surface
Recurring leaks and trapped moisture can point to problems beyond the visible covering. Those conditions need assessment before new roofing goes over them.
Repair or replace
A serviceable roof may need targeted repair. Widespread deterioration can require replacement of the covering and attention to damaged underlying components.
Your questions
A few useful answers.
Do all modified bitumen systems use the same installation method?
No. The method depends on the selected product and roof assembly. Review the actual proposed system and installation approach.
Can an older modified bitumen roof be repaired?
It may be repairable when the surrounding system remains sound. The inspection helps identify the cause, extent and suitability of a repair.
Is it suitable for every roof slope?
No roofing system is universal. Slope, drainage and the product’s installation requirements must be considered for the building.
