Free roof inspection, with a photo report of what we find.

Low-slope sections on homes

Porches, additions, garages and other low-slope sections on homes need materials suited to their pitch. Water moves off them more slowly than on steep roof planes, making seams, edges, wall junctions and outlets especially important.

Ponding water and persistent leaks

Water that remains on the roof after rain can reveal a drainage issue. Leaks may also start at a seam, an edge or the flashing where a low roof meets a wall. We look at both the visible leak and its water path; repeated surface patches alone may not correct the underlying cause.

Repair or replacement?

A localized defect may be repairable when the surrounding roof system and deck are sound. Widespread deterioration, repeated leaks or damaged decking can make replacement the more sensible choice. The inspection explains what can be repaired and what needs a broader scope.

Manufacturer product terms are separate from Matterhorn’s workmanship warranty; we make no lifetime product-warranty claim for low-slope materials.

FAQ

Flat & low-slope roof repair questions

Do you work on flat roofs on homes?

Yes. We offer residential flat and low-slope roof repair and replacement for porches, additions, garages and low-slope sections on homes.

Does ponding water mean I need a new roof?

Not automatically. We inspect the drainage, roof surface and supporting deck before recommending work. A drainage issue and a damaged roof surface may need different solutions.

What low-slope product do you install?

We install Flintlastic SA, a CertainTeed modified bitumen system. Suitability and the required installation details are assessed for the individual roof.

Can a leaking low-slope roof be repaired?

A targeted repair may be suitable when the problem is isolated and the surrounding system is sound. Repeated leaks, broad deterioration or deck damage may justify replacement instead.
